Next Step After defeating Amaury's Attack

I think the nodes need to come together and come up with a statement of principles that they vow to not deviate from. I think they should also agree on a much slower upgrade schedule than once every 6 months. Thoughts?

Stakenet (XSN) - A DEX with interchain capabilities (BTC-ETH), Huge Potential [Full Writeup]

Preface
Full disclosure here; I am heavily invested in this. I have picked up some real gems from here and was only in the position to buy so much of this because of you guys so I thought it was time to give back. I only invest in Utility Coins. These are coins that actually DO something, and provide new/build upon the crypto infrastructure to work towards the end goal that Bitcoin itself set out to achieve(financial independence from the fiat banking system). This way, I avoid 99% of the scams in crypto that are functionless vapourware, and if you only invest in things that have strong fundamentals in the long term you are much more likely to make money.
Introduction
Stakenet is a Lightning Network-ready open-source platform for decentralized applications with its native cryptocurrency – XSN. It is powered by a Proof of Stake blockchain with trustless cold staking and Masternodes. Its use case is to provide a highly secure cross-chain infrastructure for these decentralized applications, where individuals can easily operate with any blockchain simply by using Stakenet and its native currency XSN.
Ok... but what does it actually do and solve?
The moonshot here is the DEX (Decentralised Exchange) that they are building. This is a lightning-network DEX with interchain capabilities. That means you could trade BTC directly for ETH; securely, instantly, cheaply and privately.
Right now, most crypto is traded to and from Centralised Exchanges like Binance. To buy and sell on these exchanges, you have to send your crypto wallets on that exchange. That means the exchanges have your private keys, and they have control over your funds. When you use a centralised exchange, you are no longer in control of your assets, and depend on the trustworthiness of middlemen. We have in the past of course seen infamous exit scams by centralised exchanges like Mt. Gox.
The alternative? Decentralised Exchanges. DEX's have no central authority and most importantly, your private keys(your crypto) never leavesYOUR possession and are never in anyone else's possession. So you can trade peer-to-peer without any of the drawbacks of Centralised Exchanges.
The problem is that this technology has not been perfected yet, and the DEX's that we have available to us now are not providing cheap, private, quick trading on a decentralised medium because of their technological inadequacies. Take Uniswap for example. This DEX accounts for over 60% of all DEX volume and facilitates trading of ERC-20 tokens, over the Ethereum blockchain. The problem? Because of the huge amount of transaction that are occurring over the Ethereum network, this has lead to congestion(too many transaction for the network to handle at one time) so the fees have increased dramatically. Another big problem? It's only for Ethereum. You cant for example, Buy LINK with BTC. You must use ETH.
The solution? Layer 2 protocols. These are layers built ON TOP of existing blockchains, that are designed to solve the transaction and scaling difficulties that crypto as a whole is facing today(and ultimately stopping mass adoption) The developers at Stakenet have seen the big picture, and have decided to implement the lightning network(a layer 2 protocol) into its DEX from the ground up. This will facilitate the functionalities of a DEX without any of the drawbacks of the CEX's and the DEX's we have today.
Heres someone much more qualified than me, Andreas Antonopoulos, to explain this
https://streamable.com/kzpimj
'Once we have efficient, well designed DEX's on layer 2, there wont even be any DEX's on layer 1'
Progress
The Stakenet team were the first to envision this grand solution and have been working on it since its conception in June 2019. They have been making steady progress ever since and right now, the DEX is in an open beta stage where rigorous testing is constant by themselves and the public. For a project of this scale, stress testing is paramount. If the product were to launch with any bugs/errors that would result in the loss of a users funds, this would obviously be very damaging to Stakenet's reputation. So I believe that the developers conservative approach is wise.
As of now the only pairs tradeable on the DEX are XSN/BTC and LTC/BTC. The DEX has only just launched as a public beta and is not in its full public release stage yet. As development moves forward more lightning network and atomic swap compatible coins will be added to the DEX, and of course, the team are hard at work on Raiden Integration - this will allow ETH and tokens on the Ethereum blockchain to be traded on the DEX between separate blockchains(instantly, cheaply, privately) This is where Stakenet enters top 50 territory on CMC if successful and is the true value here. Raiden Integration is well underway is being tested in a closed public group on Linux.
The full public DEX with Raiden Integration is expected to release by the end of the year. Given the state of development so far and the rate of progress, this seems realistic.
Tokenomics
2.6 Metrics overview (from whitepaper)
XSN is slightly inflationary, much like ETH as this is necessary for the economy to be adopted and work in the long term. There is however a deflationary mechanism in place - all trading fees on the DEX get converted to XSN and 10% of these fees are burned. This puts constant buying pressure on XSN and acts as a deflationary mechanism. XSN has inherent value because it makes up the infrastructure that the DEX will run off and as such Masternode operators and Stakers will see the fee's from the DEX.
Conclusion
We can clearly see that a layer 2 DEX is the future of crypto currency trading. It will facilitate secure, cheap, instant and private trading across all coins with lightning capabilities, thus solving the scaling and transaction issues that are holding back crypto today. I dont need to tell you the implications of this, and what it means for crypto as a whole. If Stakenet can launch a layer 2 DEX with Raiden Integration, It will become the primary DEX in terms of volume.
Stakenet DEX will most likely be the first layer 2 DEX(first mover advantage) and its blockchain is the infrastructure that will host this DEX and subsequently receive it's trading fee's. It is not difficult to envision a time in the next year when Stakenet DEX is functional and hosting hundreds of millions of dollars worth of trading every single day.
At $30 million market cap, I cant see any other potential investment right now with this much potential upside.
This post has merely served as in introduction and a heads up for this project, there is MUCH more to cover like vortex liquidity, masternodes, TOR integration... for now, here is some additional reading. Resources
TLDR; No. Do you want to make money? I'd start with learning how to read.

Comparison between Avalanche, Cosmos and Polkadot

Comparison between Avalanche, Cosmos and Polkadot
Reposting after was mistakenly removed by mods (since resolved - Thanks)
A frequent question I see being asked is how Cosmos, Polkadot and Avalanche compare? Whilst there are similarities there are also a lot of differences. This article is not intended to be an extensive in-depth list, but rather an overview based on some of the criteria that I feel are most important.

Overview

Cosmos

Cosmos is a heterogeneous network of many independent parallel blockchains, each powered by classical BFT consensus algorithms like Tendermint. Developers can easily build custom application specific blockchains, called Zones, through the Cosmos SDK framework. These Zones connect to Hubs, which are specifically designed to connect zones together.
The vision of Cosmos is to have thousands of Zones and Hubs that are Interoperable through the Inter-Blockchain Communication Protocol (IBC). Cosmos can also connect to other systems through peg zones, which are specifically designed zones that each are custom made to interact with another ecosystem such as Ethereum and Bitcoin. Cosmos does not use Sharding with each Zone and Hub being sovereign with their own validator set.
For a more in-depth look at Cosmos and provide more reference to points made in this article, please see my three part series — Part One, Part Two, Part Three
(There's a youtube video with a quick video overview of Cosmos on the medium article - https://medium.com/ava-hub/comparison-between-avalanche-cosmos-and-polkadot-a2a98f46c03b)

Polkadot

Polkadot is a heterogeneous blockchain protocol that connects multiple specialised blockchains into one unified network. It achieves scalability through a sharding infrastructure with multiple blockchains running in parallel, called parachains, that connect to a central chain called the Relay Chain. Developers can easily build custom application specific parachains through the Substrate development framework.
The relay chain validates the state transition of connected parachains, providing shared state across the entire ecosystem. If the Relay Chain must revert for any reason, then all of the parachains would also revert. This is to ensure that the validity of the entire system can persist, and no individual part is corruptible. The shared state makes it so that the trust assumptions when using parachains are only those of the Relay Chain validator set, and no other. Interoperability is enabled between parachains through Cross-Chain Message Passing (XCMP) protocol and is also possible to connect to other systems through bridges, which are specifically designed parachains or parathreads that each are custom made to interact with another ecosystem such as Ethereum and Bitcoin. The hope is to have 100 parachains connect to the relay chain.

(There's a youtube video with a quick video overview of Polkadot on the medium article - https://medium.com/ava-hub/comparison-between-avalanche-cosmos-and-polkadot-a2a98f46c03b)

Avalanche

Avalanche is a platform of platforms, ultimately consisting of thousands of subnets to form a heterogeneous interoperable network of many blockchains, that takes advantage of the revolutionary Avalanche Consensus protocols to provide a secure, globally distributed, interoperable and trustless framework offering unprecedented decentralisation whilst being able to comply with regulatory requirements.
Avalanche allows anyone to create their own tailor-made application specific blockchains, supporting multiple custom virtual machines such as EVM and WASM and written in popular languages like Go (with others coming in the future) rather than lightly used, poorly-understood languages like Solidity. This virtual machine can then be deployed on a custom blockchain network, called a subnet, which consist of a dynamic set of validators working together to achieve consensus on the state of a set of many blockchains where complex rulesets can be configured to meet regulatory compliance.
Avalanche was built with serving financial markets in mind. It has native support for easily creating and trading digital smart assets with complex custom rule sets that define how the asset is handled and traded to ensure regulatory compliance can be met. Interoperability is enabled between blockchains within a subnet as well as between subnets. Like Cosmos and Polkadot, Avalanche is also able to connect to other systems through bridges, through custom virtual machines made to interact with another ecosystem such as Ethereum and Bitcoin.

Comparison between Cosmos, Polkadot and Avalanche

A frequent question I see being asked is how Cosmos, Polkadot and Avalanche compare? Whilst there are similarities there are also a lot of differences. This article is not intended to be an extensive in-depth list, but rather an overview based on some of the criteria that I feel are most important. For a more in-depth view I recommend reading the articles for each of the projects linked above and coming to your own conclusions. I want to stress that it’s not a case of one platform being the killer of all other platforms, far from it. There won’t be one platform to rule them all, and too often the tribalism has plagued this space. Blockchains are going to completely revolutionise most industries and have a profound effect on the world we know today. It’s still very early in this space with most adoption limited to speculation and trading mainly due to the limitations of Blockchain and current iteration of Ethereum, which all three of these platforms hope to address. For those who just want a quick summary see the image at the bottom of the article. With that said let’s have a look

Scalability

Cosmos

Each Zone and Hub in Cosmos is capable of up to around 1000 transactions per second with bandwidth being the bottleneck in consensus. Cosmos aims to have thousands of Zones and Hubs all connected through IBC. There is no limit on the number of Zones / Hubs that can be created

Polkadot

Parachains in Polkadot are also capable of up to around 1500 transactions per second. A portion of the parachain slots on the Relay Chain will be designated as part of the parathread pool, the performance of a parachain is split between many parathreads offering lower performance and compete amongst themselves in a per-block auction to have their transactions included in the next relay chain block. The number of parachains is limited by the number of validators on the relay chain, they hope to be able to achieve 100 parachains.

Avalanche

Avalanche is capable of around 4500 transactions per second per subnet, this is based on modest hardware requirements to ensure maximum decentralisation of just 2 CPU cores and 4 GB of Memory and with a validator size of over 2,000 nodes. Performance is CPU-bound and if higher performance is required then more specialised subnets can be created with higher minimum requirements to be able to achieve 10,000 tps+ in a subnet. Avalanche aims to have thousands of subnets (each with multiple virtual machines / blockchains) all interoperable with each other. There is no limit on the number of Subnets that can be created.

Results

All three platforms offer vastly superior performance to the likes of Bitcoin and Ethereum 1.0. Avalanche with its higher transactions per second, no limit on the number of subnets / blockchains that can be created and the consensus can scale to potentially millions of validators all participating in consensus scores ✅✅✅. Polkadot claims to offer more tps than cosmos, but is limited to the number of parachains (around 100) whereas with Cosmos there is no limit on the number of hubs / zones that can be created. Cosmos is limited to a fairly small validator size of around 200 before performance degrades whereas Polkadot hopes to be able to reach 1000 validators in the relay chain (albeit only a small number of validators are assigned to each parachain). Thus Cosmos and Polkadot scores ✅✅
https://preview.redd.it/2o0brllyvpq51.png?width=1000&format=png&auto=webp&s=8f62bb696ecaafcf6184da005d5fe0129d504518

Decentralisation

Cosmos

Tendermint consensus is limited to around 200 validators before performance starts to degrade. Whilst there is the Cosmos Hub it is one of many hubs in the network and there is no central hub or limit on the number of zones / hubs that can be created.

Polkadot

Polkadot has 1000 validators in the relay chain and these are split up into a small number that validate each parachain (minimum of 14). The relay chain is a central point of failure as all parachains connect to it and the number of parachains is limited depending on the number of validators (they hope to achieve 100 parachains). Due to the limited number of parachain slots available, significant sums of DOT will need to be purchased to win an auction to lease the slot for up to 24 months at a time. Thus likely to lead to only those with enough funds to secure a parachain slot. Parathreads are however an alternative for those that require less and more varied performance for those that can’t secure a parachain slot.

Avalanche

Avalanche consensus scan scale to tens of thousands of validators, even potentially millions of validators all participating in consensus through repeated sub-sampling. The more validators, the faster the network becomes as the load is split between them. There are modest hardware requirements so anyone can run a node and there is no limit on the number of subnets / virtual machines that can be created.

Results

Avalanche offers unparalleled decentralisation using its revolutionary consensus protocols that can scale to millions of validators all participating in consensus at the same time. There is no limit to the number of subnets and virtual machines that can be created, and they can be created by anyone for a small fee, it scores ✅✅✅. Cosmos is limited to 200 validators but no limit on the number of zones / hubs that can be created, which anyone can create and scores ✅✅. Polkadot hopes to accommodate 1000 validators in the relay chain (albeit these are split amongst each of the parachains). The number of parachains is limited and maybe cost prohibitive for many and the relay chain is a ultimately a single point of failure. Whilst definitely not saying it’s centralised and it is more decentralised than many others, just in comparison between the three, it scores ✅
https://preview.redd.it/ckfamee0wpq51.png?width=1000&format=png&auto=webp&s=c4355f145d821fabf7785e238dbc96a5f5ce2846

Latency

Cosmos

Tendermint consensus used in Cosmos reaches finality within 6 seconds. Cosmos consists of many Zones and Hubs that connect to each other. Communication between 2 zones could pass through many hubs along the way, thus also can contribute to latency times depending on the path taken as explained in part two of the articles on Cosmos. It doesn’t need to wait for an extended period of time with risk of rollbacks.

Polkadot

Polkadot provides a Hybrid consensus protocol consisting of Block producing protocol, BABE, and then a finality gadget called GRANDPA that works to agree on a chain, out of many possible forks, by following some simpler fork choice rule. Rather than voting on every block, instead it reaches agreements on chains. As soon as more than 2/3 of validators attest to a chain containing a certain block, all blocks leading up to that one are finalized at once.
If an invalid block is detected after it has been finalised then the relay chain would need to be reverted along with every parachain. This is particularly important when connecting to external blockchains as those don’t share the state of the relay chain and thus can’t be rolled back. The longer the time period, the more secure the network is, as there is more time for additional checks to be performed and reported but at the expense of finality. Finality is reached within 60 seconds between parachains but for external ecosystems like Ethereum their state obviously can’t be rolled back like a parachain and so finality will need to be much longer (60 minutes was suggested in the whitepaper) and discussed in more detail in part three

Avalanche

Avalanche consensus achieves finality within 3 seconds, with most happening sub 1 second, immutable and completely irreversible. Any subnet can connect directly to another without having to go through multiple hops and any VM can talk to another VM within the same subnet as well as external subnets. It doesn’t need to wait for an extended period of time with risk of rollbacks.

Results

With regards to performance far too much emphasis is just put on tps as a metric, the other equally important metric, if not more important with regards to finance is latency. Throughput measures the amount of data at any given time that it can handle whereas latency is the amount of time it takes to perform an action. It’s pointless saying you can process more transactions per second than VISA when it takes 60 seconds for a transaction to complete. Low latency also greatly increases general usability and customer satisfaction, nowadays everyone expects card payments, online payments to happen instantly. Avalanche achieves the best results scoring ✅✅✅, Cosmos with comes in second with 6 second finality ✅✅ and Polkadot with 60 second finality (which may be 60 minutes for external blockchains) scores ✅
https://preview.redd.it/kzup5x42wpq51.png?width=1000&format=png&auto=webp&s=320eb4c25dc4fc0f443a7a2f7ff09567871648cd

Shared Security

Cosmos

Every Zone and Hub in Cosmos has their own validator set and different trust assumptions. Cosmos are researching a shared security model where a Hub can validate the state of connected zones for a fee but not released yet. Once available this will make shared security optional rather than mandatory.

Polkadot

Shared Security is mandatory with Polkadot which uses a Shared State infrastructure between the Relay Chain and all of the connected parachains. If the Relay Chain must revert for any reason, then all of the parachains would also revert. Every parachain makes the same trust assumptions, and as such the relay chain validates state transition and enables seamless interoperability between them. In return for this benefit, they have to purchase DOT and win an auction for one of the available parachain slots.
However, parachains can’t just rely on the relay chain for their security, they will also need to implement censorship resistance measures and utilise proof of work / proof of stake for each parachain as well as discussed in part three, thus parachains can’t just rely on the security of the relay chain, they need to ensure sybil resistance mechanisms using POW and POS are implemented on the parachain as well.

Avalanche

A subnet in Avalanche consists of a dynamic set of validators working together to achieve consensus on the state of a set of many blockchains where complex rulesets can be configured to meet regulatory compliance. So unlike in Cosmos where each zone / hub has their own validators, A subnet can validate a single or many virtual machines / blockchains with a single validator set. Shared security is optional

Results

Shared security is mandatory in polkadot and a key design decision in its infrastructure. The relay chain validates the state transition of all connected parachains and thus scores ✅✅✅. Subnets in Avalanche can validate state of either a single or many virtual machines. Each subnet can have their own token and shares a validator set, where complex rulesets can be configured to meet regulatory compliance. It scores ✅ ✅. Every Zone and Hub in cosmos has their own validator set / token but research is underway to have the hub validate the state transition of connected zones, but as this is still early in the research phase scores ✅ for now.

Current Adoption

Cosmos

The Cosmos project started in 2016 with an ICO held in April 2017. There are currently around 50 projects building on the Cosmos SDK with a full list can be seen here and filtering for Cosmos SDK . Not all of the projects will necessarily connect using native cosmos sdk and IBC and some have forked parts of the Cosmos SDK and utilise the tendermint consensus such as Binance Chain but have said they will connect in the future.

Polkadot

The Polkadot project started in 2016 with an ICO held in October 2017. There are currently around 70 projects building on Substrate and a full list can be seen here and filtering for Substrate Based. Like with Cosmos not all projects built using substrate will necessarily connect to Polkadot and parachains or parathreads aren’t currently implemented in either the Live or Test network (Kusama) as of the time of this writing.

Avalanche

Avalanche in comparison started much later with Ava Labs being founded in 2018. Avalanche held it’s ICO in July 2020. Due to lot shorter time it has been in development, the number of projects confirmed are smaller with around 14 projects currently building on Avalanche. Due to the customisability of the platform though, many virtual machines can be used within a subnet making the process incredibly easy to port projects over. As an example, it will launch with the Ethereum Virtual Machine which enables byte for byte compatibility and all the tooling like Metamask, Truffle etc. will work, so projects can easily move over to benefit from the performance, decentralisation and low gas fees offered. In the future Cosmos and Substrate virtual machines could be implemented on Avalanche.

Results

Whilst it’s still early for all 3 projects (and the entire blockchain space as a whole), there is currently more projects confirmed to be building on Cosmos and Polkadot, mostly due to their longer time in development. Whilst Cosmos has fewer projects, zones are implemented compared to Polkadot which doesn’t currently have parachains. IBC to connect zones and hubs together is due to launch Q2 2021, thus both score ✅✅✅. Avalanche has been in development for a lot shorter time period, but is launching with an impressive feature set right from the start with ability to create subnets, VMs, assets, NFTs, permissioned and permissionless blockchains, cross chain atomic swaps within a subnet, smart contracts, bridge to Ethereum etc. Applications can easily port over from other platforms and use all the existing tooling such as Metamask / Truffle etc but benefit from the performance, decentralisation and low gas fees offered. Currently though just based on the number of projects in comparison it scores ✅.

Enterprise Adoption

Cosmos

Cosmos enables permissioned and permissionless zones which can connect to each other with the ability to have full control over who validates the blockchain. For permissionless zones each zone / hub can have their own token and they are in control who validates.

Polkadot

With polkadot the state transition is performed by a small randomly selected assigned group of validators from the relay chain plus with the possibility that state is rolled back if an invalid transaction of any of the other parachains is found. This may pose a problem for enterprises that need complete control over who performs validation for regulatory reasons. In addition due to the limited number of parachain slots available Enterprises would have to acquire and lock up large amounts of a highly volatile asset (DOT) and have the possibility that they are outbid in future auctions and find they no longer can have their parachain validated and parathreads don’t provide the guaranteed performance requirements for the application to function.

Avalanche

Avalanche enables permissioned and permissionless subnets and complex rulesets can be configured to meet regulatory compliance. For example a subnet can be created where its mandatory that all validators are from a certain legal jurisdiction, or they hold a specific license and regulated by the SEC etc. Subnets are also able to scale to tens of thousands of validators, and even potentially millions of nodes, all participating in consensus so every enterprise can run their own node rather than only a small amount. Enterprises don’t have to hold large amounts of a highly volatile asset, but instead pay a fee in AVAX for the creation of the subnets and blockchains which is burnt.

Results

Avalanche provides the customisability to run private permissioned blockchains as well as permissionless where the enterprise is in control over who validates the blockchain, with the ability to use complex rulesets to meet regulatory compliance, thus scores ✅✅✅. Cosmos is also able to run permissioned and permissionless zones / hubs so enterprises have full control over who validates a blockchain and scores ✅✅. Polkadot requires locking up large amounts of a highly volatile asset with the possibility of being outbid by competitors and being unable to run the application if the guaranteed performance is required and having to migrate away. The relay chain validates the state transition and can roll back the parachain should an invalid block be detected on another parachain, thus scores ✅.
https://preview.redd.it/li5jy6u6wpq51.png?width=1000&format=png&auto=webp&s=e2a95f1f88e5efbcf9e23c789ae0f002c8eb73fc

Interoperability

Cosmos

Cosmos will connect Hubs and Zones together through its IBC protocol (due to release in Q1 2020). Connecting to blockchains outside of the Cosmos ecosystem would either require the connected blockchain to fork their code to implement IBC or more likely a custom “Peg Zone” will be created specific to work with a particular blockchain it’s trying to bridge to such as Ethereum etc. Each Zone and Hub has different trust levels and connectivity between 2 zones can have different trust depending on which path it takes (this is discussed more in this article). Finality time is low at 6 seconds, but depending on the number of hops, this can increase significantly.

Polkadot

Polkadot’s shared state means each parachain that connects shares the same trust assumptions, of the relay chain validators and that if one blockchain needs to be reverted, all of them will need to be reverted. Interoperability is enabled between parachains through Cross-Chain Message Passing (XCMP) protocol and is also possible to connect to other systems through bridges, which are specifically designed parachains or parathreads that each are custom made to interact with another ecosystem such as Ethereum and Bitcoin. Finality time between parachains is around 60 seconds, but longer will be needed (initial figures of 60 minutes in the whitepaper) for connecting to external blockchains. Thus limiting the appeal of connecting two external ecosystems together through Polkadot. Polkadot is also limited in the number of Parachain slots available, thus limiting the amount of blockchains that can be bridged. Parathreads could be used for lower performance bridges, but the speed of future blockchains is only going to increase.

Avalanche

A subnet can validate multiple virtual machines / blockchains and all blockchains within a subnet share the same trust assumptions / validator set, enabling cross chain interoperability. Interoperability is also possible between any other subnet, with the hope Avalanche will consist of thousands of subnets. Each subnet may have a different trust level, but as the primary network consists of all validators then this can be used as a source of trust if required. As Avalanche supports many virtual machines, bridges to other ecosystems are created by running the connected virtual machine. There will be an Ethereum bridge using the EVM shortly after mainnet. Finality time is much faster at sub 3 seconds (with most happening under 1 second) with no chance of rolling back so more appealing when connecting to external blockchains.

Results

All 3 systems are able to perform interoperability within their ecosystem and transfer assets as well as data, as well as use bridges to connect to external blockchains. Cosmos has different trust levels between its zones and hubs and can create issues depending on which path it takes and additional latency added. Polkadot provides the same trust assumptions for all connected parachains but has long finality and limited number of parachain slots available. Avalanche provides the same trust assumptions for all blockchains within a subnet, and different trust levels between subnets. However due to the primary network consisting of all validators it can be used for trust. Avalanche also has a much faster finality time with no limitation on the number of blockchains / subnets / bridges that can be created. Overall all three blockchains excel with interoperability within their ecosystem and each score ✅✅.

Tokenomics

Cosmos

The ATOM token is the native token for the Cosmos Hub. It is commonly mistaken by people that think it’s the token used throughout the cosmos ecosystem, whereas it’s just used for one of many hubs in Cosmos, each with their own token. Currently ATOM has little utility as IBC isn’t released and has no connections to other zones / hubs. Once IBC is released zones may prefer to connect to a different hub instead and so ATOM is not used. ATOM isn’t a fixed capped supply token and supply will continuously increase with a yearly inflation of around 10% depending on the % staked. The current market cap for ATOM as of the time of this writing is $1 Billion with 203 million circulating supply. Rewards can be earnt through staking to offset the dilution caused by inflation. Delegators can also get slashed and lose a portion of their ATOM should the validator misbehave.

Polkadot

Polkadot’s native token is DOT and it’s used to secure the Relay Chain. Each parachain needs to acquire sufficient DOT to win an auction on an available parachain lease period of up to 24 months at a time. Parathreads have a fixed fee for registration that would realistically be much lower than the cost of acquiring a parachain slot and compete with other parathreads in a per-block auction to have their transactions included in the next relay chain block. DOT isn’t a fixed capped supply token and supply will continuously increase with a yearly inflation of around 10% depending on the % staked. The current market cap for DOT as of the time of this writing is $4.4 Billion with 852 million circulating supply. Delegators can also get slashed and lose their DOT (potentially 100% of their DOT for serious attacks) should the validator misbehave.

Avalanche

AVAX is the native token for the primary network in Avalanche. Every validator of any subnet also has to validate the primary network and stake a minimum of 2000 AVAX. There is no limit to the number of validators like other consensus methods then this can cater for tens of thousands even potentially millions of validators. As every validator validates the primary network, this can be a source of trust for interoperability between subnets as well as connecting to other ecosystems, thus increasing amount of transaction fees of AVAX. There is no slashing in Avalanche, so there is no risk to lose your AVAX when selecting a validator, instead rewards earnt for staking can be slashed should the validator misbehave. Because Avalanche doesn’t have direct slashing, it is technically possible for someone to both stake AND deliver tokens for something like a flash loan, under the invariant that all tokens that are staked are returned, thus being able to make profit with staked tokens outside of staking itself.
There will also be a separate subnet for Athereum which is a ‘spoon,’ or friendly fork, of Ethereum, which benefits from the Avalanche consensus protocol and applications in the Ethereum ecosystem. It’s native token ATH will be airdropped to ETH holders as well as potentially AVAX holders as well. This can be done for other blockchains as well.
Transaction fees on the primary network for all 3 of the blockchains as well as subscription fees for creating a subnet and blockchain are paid in AVAX and are burnt, creating deflationary pressure. AVAX is a fixed capped supply of 720 million tokens, creating scarcity rather than an unlimited supply which continuously increase of tokens at a compounded rate each year like others. Initially there will be 360 tokens minted at Mainnet with vesting periods between 1 and 10 years, with tokens gradually unlocking each quarter. The Circulating supply is 24.5 million AVAX with tokens gradually released each quater. The current market cap of AVAX is around $100 million.

Results

Avalanche’s AVAX with its fixed capped supply, deflationary pressure, very strong utility, potential to receive air drops and low market cap, means it scores ✅✅✅. Polkadot’s DOT also has very strong utility with the need for auctions to acquire parachain slots, but has no deflationary mechanisms, no fixed capped supply and already valued at $3.8 billion, therefore scores ✅✅. Cosmos’s ATOM token is only for the Cosmos Hub, of which there will be many hubs in the ecosystem and has very little utility currently. (this may improve once IBC is released and if Cosmos hub actually becomes the hub that people want to connect to and not something like Binance instead. There is no fixed capped supply and currently valued at $1.1 Billion, so scores ✅.

All three are excellent projects and have similarities as well as many differences. Just to reiterate this article is not intended to be an extensive in-depth list, but rather an overview based on some of the criteria that I feel are most important. For a more in-depth view I recommend reading the articles for each of the projects linked above and coming to your own conclusions, you may have different criteria which is important to you, and score them differently. There won’t be one platform to rule them all however, with some uses cases better suited to one platform over another, and it’s not a zero-sum game. Blockchain is going to completely revolutionize industries and the Internet itself. The more projects researching and delivering breakthrough technology the better, each learning from each other and pushing each other to reach that goal earlier. The current market is a tiny speck of what’s in store in terms of value and adoption and it’s going to be exciting to watch it unfold.

Hans Moog [IF]어제 오후 2:45
So why don't we just copy Avalanche? Well that's pretty simple ...
📷
Hans Moog [IF]어제 오후 2:47
1. It doesn't scale very well with the amount of nodes in the network that have no say in the consensus process but are merely consensus consuming nodes (i.e. sensors, edge devices and so on). If you assume that the network will never have more than a few thousand nodes then thats fine but if you want to build a DLT that can cope with millions of devices then it wont work because of the message complexity.
2. If somebody starts spamming conflicts, then the whole network will stop to confirm any transactions and will grind to a halt until the conflict spamming stops. Avalanche thinks that this is not a huge problem because an attacker would have to spend fees for spamming conflicts which means that he couldn't do this forever and would at some point run out of funds.
IOTA tries to build a feeless protocol and a consensus that stops to function if somebody spams conflicts is really not an option for us.
3. If a medium sized validator goes offline due to whatever reason, then the whole network will again stop to confirm any transactions because whenever a query for a nodes opinion can not be answered they reset the counter for consecutive successful voting rounds which will prevent confirmations. Since nodes need to open some ports to be available for queries it is super easy to DDOS validators and again bring the network confirmations to 0.
📷
Hans Moog [IF]어제 오후 3:05
4. Avalanche still processes transactions in "chunks/blocks" by only applying them after they have gone through some consensus process (gathered enough successfull voting rounds), which means that the nodes will waste a significant amount of time where they "wait" for the next chunk to be finished before the transactions are applied to the ledger state. IOTA tries to streamline this process by decoupling consensus and the booking of transactions by using the "parallel reality based ledger state" which means that nodes in IOTA will never waste any time "waiting" for decisions to be made. This will give us much higher throughput numbers.
📷
Hans Moog [IF]어제 오후 3:11
5. Avalanche has some really severe game theoretic problems where nodes are incentivized to attach their transactions to the already decided parts of the DAG because then things like conflict spam won't affect these transactions as badly as the transactions issued by honest nodes. If however every node would follow this "better and selfish" tip selection mechanism then the network will stop to work at all.
Overall the "being able to stop consensus" might not be too bad since you can't really do anything really bad (i.e. double spend) which is why we might not see these kind of attacks in the immediate future but just wait until a few DeFi apps are running on their platform where smart contracts are actually relying on more or less real time execution of the contracts. Then there might be some actual financial gains to be made if the contract halts and we might see alot of these things appear (including selfish tip selection).
Avalanche is barely a top 100 project and nobody attacks these kind of low value networks unless there is something to be gained from such an attack. Saying that the fact that its live on mainnet and hasn't been attacked in 3 weeks is a proof for its security is completely wrong.
Especially considering that 95% of all stake are controlled by avalanche itself
If you control > 50% of the voting power then you essentially control the whole network and attacks can mostly be ignored
I guess there is a reason for avalanche only selling 10% of the token supply to the public because then some of the named problems are less likely to appear

Navin Ramachandran [IF]어제 오후 3:21
I have to say that wtf's suggestion is pretty condescending to all our researchers. It seems heavy on the troll aspect to suggest that we should ditch all our work because iota is only good at industrial adoption. Does wtf actually expect a response to this? Or is this grand standing?
📷
Hans Moog [IF]어제 오후 3:22
The whole argument of "why don't you just use X instead of trying to build a better version" is also a completely idiotic argument. Why did ETH write their own protocol if Bitcoin was already around? Well because they saw problems in Bitcoins approach and tried to improve it.
📷
Hans Moog [IF]어제 오후 3:27
u/Navin Ramachandran [IF] Its like most of his arguments ... remember when he said we should implement colored coins in 2nd layer smart contracts instead of the base layer because they would be more expressive (i.e. turing complete) completely discarding that 2nd layer smart contracts only really work if you have a consensus on data and therefore state for which you need the "traceability" of funds to create these kind of mini blockchains in the tangle?
Colored coins "enable" smart contracts and it wouldnt work the other way round - unless you have a platform that works exactly like ETH where all the nodes validate a single shared execution platform of the smart contracts which is not really scalable and is exactly what we are trying to solve with our approach.
📷
Navin Ramachandran [IF]어제 오후 3:28
Always easier to criticise than build something yourself. But yet he keeps posting these inflammatory posts.
At this point is there any doubt if he is making these comments constructively?
📷
Hans Moog [IF]어제 오후 3:43
If he at least would try to understand IOTAs vision ... then maybe he wouldn't have to ask things like "Why don't you just copy a tech that only works with fees"
📷
Hans Moog [IF]어제 오후 4:35
u/Shaar
I thought this would only be used to 'override' finality, eg if there were network splits. But not in normal consensus
That is not correct. Every single transaction gets booked on arrival using the parallel reality based ledger state. If there are conflicts then we create a "branch" (container in the ledger state) that represents the perception that this particular double spend would be accepted by consensus. After consensus is reached, the container is simply marked as "accepted" and all transactions that are associated with this branch are immediately confirmed as well. This allows us to make the node use all of its computing ressources 24/7 without having to wait for any kind of decision to be made and allows us to scale the throughput to its physical limits. That's the whole idea of the "parallel reality based ledger state" instead of designing a data structure that models the ledger state "after consensus" like everybody else is doing it is tailored to model the ledger state "before consensus" and then you just flip a flag to persist your decision. The "resync mechanism" also uses the branches to measure the amount of approval a certain perception of the ledger state receives. So if my own opinion is not in line with what the rest of the network has accepted (i.e. because I was eclipsed or because there was a network split), then I can use the weight of these branches to detect this "being out of sync" and can do another larger query to re-evaluate my decision.(수정됨)
Also what happens in IOTA if DRNG notes would fall out, does the network continue if no new RNGs appear for a while? Or will new nodes be added sufficiently fast to the DRNG committee that no one notices?
Its a comittee and not just a single DRNG provider. If a few nodes fail then it will still produce random numbers. And even if the whole comittee fails there are fallback RNG's that would be used instead
📷
Hans Moog [IF]어제 오후 4:58
And multiverse doesn't use FPC but only the weight of these branches in the same way as blockchain uses the longest chain wins consensus to choose between conflicts. So nodes simply attach their transactions to the transactions that they have seen first and if there are conflicts then you simply monitor which version received more approval and adjust your opinion accordingly.
📷
Hans Moog [IF]어제 오후 5:07
We started integrating some of the non-controversial concepts (like the approval reset switch) into FPC and are currently refactoring goshimmer to support this
We are also planning to make the big mana holders publish their opinion in the tangle as a public statement, which allows us to measure the rate of approval in a similar way as multiverse would do it
So its starting to converge a bit but we are still using FPC as a metastability breaking mechanism
Once the changes are implemented it should be pretty easy to simulate and test both approaches in parallel
📷
Serguei Popov [IF]어제 오후 5:53
So the ask is that we ditch all our work and fork Avalanche because it has not been attacked in the month or so it has been up?
u/Navin Ramachandran [IF] yeah, that's hilarious. Avalanche consensus (at least their WP version) is clearly scientifically unsound.
📷
Hans Moog [IF]어제 오후 9:43
u/wtf maybe you should research avalanche before proposing such a stupid idea
and you will see that what I wrote is actually true
📷
Hans Moog [IF]어제 오후 9:44
paying fees is what "protects" them atm
and simply the fact that nobody uses the network for anything of value yet
we cant rely on fees making attack vectors "inattractive"
📷
Serguei Popov [IF]어제 오후 10:17
well (1.) very obviously the metastability problems are not a problem in practice,
putting "very obviously" before questionable statements very obviously shows that you are seeking a constructive dialogue 📷 (to make metastability work, the adversary needs to more-or-less know the current opinion vectors of most of the honest participants; I don't see why a sufficiently well-connected adversary cannot query enough honest nodes frequently enough to achieve that)
(2.) .... you'd need an unpredictable number every few tens/hundreds milliseconds, but your DRNG can only produce one every O(seconds).
the above assumption (about "every few tens/hundreds milliseconds") is wrong
We've had this discussion before, where you argued that the assumptions in the FPC-BI paper (incl. "all nodes must be known") are not to be taken 100% strictly, and that the results are to be seen more of an indication of overall performance.
Aham, I see. So, unfortunately, all that time that I invested into explaining that stuff during our last conversation was for nothing. Again, very briefly. The contents of the FPC-BI paper is not "an indication of overall performance". It rather shows (to someone who actually read and understood the paper) why the approach is sound and robust, as it makes one understand what is the mechanism that causes the consensus phenomenon occur.
Yet you don't allow for that same argument to be valid for the "metastability" problem in avalanche,
Incorrect. It's not "that same argument". FPC-BI is a decent academic paper that has precisely formulated results and proofs. The Ava WP (the probabilistic part of it), on the other hand, does not contain proofs of what they call results. More importantly, they don't even show a clear path to those proofs. That's why their system is scientifically unsound.
even when there's a live network that shows that it doesn't matter.
No, it doesn't show that it doesn't matter. It only shows that it works when not properly attacked. Their WP doesn't contain any insight on why those attacks would be difficult/impossible.
📷
Hans Moog [IF]어제 오후 10:56
That proposal was so stupid - Avalanche does several things completely different and we are putting quite a bit og effort into our solution to pretty much fix all of Avalanches shortcomings
If we just wanted to have a working product and dont care about security or performance then we could have just forked a blockchaib
I am pretty confident that once we are done - its going to be extremely close to the besttheoretical thresholds that DLTs will ever be able to achieve for an unsharded baselayer

Yesterday I was asked how a reasonably big company no one has heard of could best move forward implementing Access for thousands of locations worldwide. (Sorry for the vagueness, it’s all confidential.) They read the article and want to implement it because it seems to fit a problem they’re currently trying to solve. Such moves will vastly increase the utility of protocols like IOTA, and is what the speculation is built on. I do not think you can overestimate what impact Access is going to have. It’s cutting out the middleman for simple things; no server or service needed. That’s huge.
So yes, I think this space will continue to grow u/Coinnave

In short: we are planning a new v0.3.0 release that should happen very soon. This version will bring fundamental changes to the structure of the entire codebase (but without additional features) so that progressing with the development will be easier and more consistent. We have also obtained outstanding results with the dRNG committee managed by the GoShimmer X-Team, so that will also be integral part of v0.3.0. After that, we will merge the Value Tangle with the Message Tangle, so to have only one Tangle and make the TSA and the orphanage easier to manage. And we are also progressing really well with Mana, that will be the focus after the merge. More or less this is what is going to happen this month.
We will release further details with the upcoming Research Status Update 📷

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Public Proposal TL;DR:

Dragonchain has demonstrated twice Reddit’s entire total daily volume (votes, comments, and posts per Reddit 2019 Year in Review) in a 24-hour demo on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. At the time, in January 2020, the entire cost of the demo was approximately $25K on a single system (transaction fees locked at $0.0001/txn). With current fees (lowest fee $0.0000025/txn), this would cost as little as $625.
Watch Joe walk through the entire proposal and answer questions on YouTube.
This proposal is also available on the Dragonchain blog.

Hello Reddit and Ethereum community!

I’m Joe Roets, Founder & CEO of Dragonchain. When the team and I first heard about The Great Reddit Scaling Bake-Off we were intrigued. We believe we have the solutions Reddit seeks for its community points system and we have them at scale.
For your consideration, we have submitted our proposal below. The team at Dragonchain and I welcome and look forward to your technical questions, philosophical feedback, and fair criticism, to build a scaling solution for Reddit that will empower its users. Because our architecture is unlike other blockchain platforms out there today, we expect to receive many questions while people try to grasp our project. I will answer all questions here in this thread on Reddit, and I've answered some questions in the stream on YouTube.
We have seen good discussions so far in the competition. We hope that Reddit’s scaling solution will emerge from The Great Reddit Scaling Bake-Off and that Reddit will have great success with the implementation.

Executive summary

Dragonchain is a robust open source hybrid blockchain platform that has proven to withstand the passing of time since our inception in 2014. We have continued to evolve to harness the scalability of private nodes, yet take full advantage of the security of public decentralized networks, like Ethereum. We have a live, operational, and fully functional Interchain network integrating Bitcoin, Ethereum, Ethereum Classic, and ~700 independent Dragonchain nodes. Every transaction is secured to Ethereum, Bitcoin, and Ethereum Classic. Transactions are immediately usable on chain, and the first decentralization is seen within 20 seconds on Dragon Net. Security increases further to public networks ETH, BTC, and ETC within 10 minutes to 2 hours. Smart contracts can be written in any executable language, offering full freedom to existing developers. We invite any developer to watch the demo, play with our SDK’s, review open source code, and to help us move forward. Dragonchain specializes in scalable loyalty & rewards solutions and has built a decentralized social network on chain, with very affordable transaction costs. This experience can be combined with the insights Reddit and the Ethereum community have gained in the past couple of months to roll out the solution at a rapid pace.

Response and PoC

In The Great Reddit Scaling Bake-Off post, Reddit has asked for a series of demonstrations, requirements, and other considerations. In this section, we will attempt to answer all of these requests.

Live Demo

A live proof of concept showing hundreds of thousands of transactions
On Jan 7, 2020, Dragonchain hosted a 24-hour live demonstration during which a quarter of a billion (250 million+) transactions executed fully on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. This means that every single transaction is secured by, and traceable to these networks. An attack on this system would require a simultaneous attack on all of the Interchained networks.
24 hours in 4 minutes (YouTube):
24 hours in 4 minutes
The demonstration was of a single business system, and any user is able to scale this further, by running multiple systems simultaneously. Our goals for the event were to demonstrate a consistent capacity greater than that of Visa over an extended time period.
Tooling to reproduce our demo is available here:
https://github.com/dragonchain/spirit-bomb

Source Code

Source code (for on & off-chain components as well tooling used for the PoC). The source code does not have to be shared publicly, but if Reddit decides to use a particular solution it will need to be shared with Reddit at some point.

Scaling

How it works & scales

Architectural Scaling

Dragonchain’s architecture attacks the scalability issue from multiple angles. Dragonchain is a hybrid blockchain platform, wherein every transaction is protected on a business node to the requirements of that business or purpose. A business node may be held completely private or may be exposed or replicated to any level of exposure desired.
Every node has its own blockchain and is independently scalable. Dragonchain established Context Based Verification as its consensus model. Every transaction is immediately usable on a trust basis, and in time is provable to an increasing level of decentralized consensus. A transaction will have a level of decentralization to independently owned and deployed Dragonchain nodes (~700 nodes) within seconds, and full decentralization to BTC and ETH within minutes or hours. Level 5 nodes (Interchain nodes) function to secure all transactions to public or otherwise external chains such as Bitcoin and Ethereum. These nodes scale the system by aggregating multiple blocks into a single Interchain transaction on a cadence. This timing is configurable based upon average fees for each respective chain. For detailed information about Dragonchain’s architecture, and Context Based Verification, please refer to the Dragonchain Architecture Document.

Economic Scaling

An interesting feature of Dragonchain’s network consensus is its economics and scarcity model. Since Dragon Net nodes (L2-L4) are independent staking nodes, deployment to cloud platforms would allow any of these nodes to scale to take on a large percentage of the verification work. This is great for scalability, but not good for the economy, because there is no scarcity, and pricing would develop a downward spiral and result in fewer verification nodes. For this reason, Dragonchain uses TIME as scarcity.
TIME is calculated as the number of Dragons held, multiplied by the number of days held. TIME influences the user’s access to features within the Dragonchain ecosystem. It takes into account both the Dragon balance and length of time each Dragon is held. TIME is staked by users against every verification node and dictates how much of the transaction fees are awarded to each participating node for every block.
TIME also dictates the transaction fee itself for the business node. TIME is staked against a business node to set a deterministic transaction fee level (see transaction fee table below in Cost section). This is very interesting in a discussion about scaling because it guarantees independence for business implementation. No matter how much traffic appears on the entire network, a business is guaranteed to not see an increased transaction fee rate.

Scaled Deployment

Dragonchain uses Docker and Kubernetes to allow the use of best practices traditional system scaling. Dragonchain offers managed nodes with an easy to use web based console interface. The user may also deploy a Dragonchain node within their own datacenter or favorite cloud platform. Users have deployed Dragonchain nodes on-prem on Amazon AWS, Google Cloud, MS Azure, and other hosting platforms around the world. Any executable code, anything you can write, can be written into a smart contract. This flexibility is what allows us to say that developers with no blockchain experience can use any code language to access the benefits of blockchain. Customers have used NodeJS, Python, Java, and even BASH shell script to write smart contracts on Dragonchain.
With Docker containers, we achieve better separation of concerns, faster deployment, higher reliability, and lower response times.
We chose Kubernetes for its self-healing features, ability to run multiple services on one server, and its large and thriving development community. It is resilient, scalable, and automated. OpenFaaS allows us to package smart contracts as Docker images for easy deployment.
Contract deployment time is now bounded only by the size of the Docker image being deployed but remains fast even for reasonably large images. We also take advantage of Docker’s flexibility and its ability to support any language that can run on x86 architecture. Any image, public or private, can be run as a smart contract using Dragonchain.

Flexibility in Scaling

Dragonchain’s architecture considers interoperability and integration as key features. From inception, we had a goal to increase adoption via integration with real business use cases and traditional systems.
We envision the ability for Reddit, in the future, to be able to integrate alternate content storage platforms or other financial services along with the token.
  • LBRY - To allow users to deploy content natively to LBRY
  • MakerDAO to allow users to lend small amounts backed by their Reddit community points.
  • STORJ/SIA to allow decentralized on chain storage of portions of content. These integrations or any other are relatively easy to integrate on Dragonchain with an Interchain implementation.

Cost

Cost estimates (on-chain and off-chain) For the purpose of this proposal, we assume that all transactions are on chain (posts, replies, and votes).
On the Dragonchain network, transaction costs are deterministic/predictable. By staking TIME on the business node (as described above) Reddit can reduce transaction costs to as low as $0.0000025 per transaction.
Dragonchain Fees Table

Getting Started

How to run it
Building on Dragonchain is simple and requires no blockchain experience. Spin up a business node (L1) in our managed environment (AWS), run it in your own cloud environment, or on-prem in your own datacenter. Clear documentation will walk you through the steps of spinning up your first Dragonchain Level 1 Business node.
Getting started is easy...
  1. Download Dragonchain’s dctl
  2. Input three commands into a terminal
  3. Build an image
  4. Run it
More information can be found in our Get started documents.

Architecture
Dragonchain is an open source hybrid platform. Through Dragon Net, each chain combines the power of a public blockchain (like Ethereum) with the privacy of a private blockchain.
Dragonchain organizes its network into five separate levels. A Level 1, or business node, is a totally private blockchain only accessible through the use of public/private keypairs. All business logic, including smart contracts, can be executed on this node directly and added to the chain.
After creating a block, the Level 1 business node broadcasts a version stripped of sensitive private data to Dragon Net. Three Level 2 Validating nodes validate the transaction based on guidelines determined from the business. A Level 3 Diversity node checks that the level 2 nodes are from a diverse array of locations. A Level 4 Notary node, hosted by a KYC partner, then signs the validation record received from the Level 3 node. The transaction hash is ledgered to the Level 5 public chain to take advantage of the hash power of massive public networks.
Dragon Net can be thought of as a “blockchain of blockchains”, where every level is a complete private blockchain. Because an L1 can send to multiple nodes on a single level, proof of existence is distributed among many places in the network. Eventually, proof of existence reaches level 5 and is published on a public network.

SDK Source

Nobody’s Perfect

Known issues or tradeoffs
  • Dragonchain is open source and even though the platform is easy enough for developers to code in any language they are comfortable with, we do not have so large a developer community as Ethereum. We would like to see the Ethereum developer community (and any other communities) become familiar with our SDK’s, our solutions, and our platform, to unlock the full potential of our Ethereum Interchain. Long ago we decided to prioritize both Bitcoin and Ethereum Interchains. We envision an ecosystem that encompasses different projects to give developers the ability to take full advantage of all the opportunities blockchain offers to create decentralized solutions not only for Reddit but for all of our current platforms and systems. We believe that together we will take the adoption of blockchain further. We currently have additional Interchain with Ethereum Classic. We look forward to Interchain with other blockchains in the future. We invite all blockchains projects who believe in decentralization and security to Interchain with Dragonchain.
  • While we only have 700 nodes compared to 8,000 Ethereum and 10,000 Bitcoin nodes. We harness those 18,000 nodes to scale to extremely high levels of security. See Dragonchain metrics.
  • Some may consider the centralization of Dragonchain’s business nodes as an issue at first glance, however, the model is by design to protect business data. We do not consider this a drawback as these nodes can make any, none, or all data public. Depending upon the implementation, every subreddit could have control of its own business node, for potential business and enterprise offerings, bringing new alternative revenue streams to Reddit.

Costs and resources

Summary of cost & resource information for both on-chain & off-chain components used in the PoC, as well as cost & resource estimates for further scaling. If your PoC is not on mainnet, make note of any mainnet caveats (such as congestion issues).
Every transaction on the PoC system had a transaction fee of $0.0001 (one-hundredth of a cent USD). At 256MM transactions, the demo cost $25,600. With current operational fees, the same demonstration would cost $640 USD.
For the demonstration, to achieve throughput to mimic a worldwide payments network, we modeled several clients in AWS and 4-5 business nodes to handle the traffic. The business nodes were tuned to handle higher throughput by adjusting memory and machine footprint on AWS. This flexibility is valuable to implementing a system such as envisioned by Reddit. Given that Reddit’s daily traffic (posts, replies, and votes) is less than half that of our demo, we would expect that the entire Reddit system could be handled on 2-5 business nodes using right-sized containers on AWS or similar environments.
Verification was accomplished on the operational Dragon Net network with over 700 independently owned verification nodes running around the world at no cost to the business other than paid transaction fees.

Requirements

Scaling

This PoC should scale to the numbers below with minimal costs (both on & off-chain). There should also be a clear path to supporting hundreds of millions of users.
Over a 5 day period, your scaling PoC should be able to handle:
*100,000 point claims (minting & distributing points) *25,000 subscriptions *75,000 one-off points burning *100,000 transfers
During Dragonchain’s 24 hour demo, the above required numbers were reached within the first few minutes.
Reddit’s total activity is 9000% more than Ethereum’s total transaction level. Even if you do not include votes, it is still 700% more than Ethereum’s current volume. Dragonchain has demonstrated that it can handle 250 million transactions a day, and it’s architecture allows for multiple systems to work at that level simultaneously. In our PoC, we demonstrate double the full capacity of Reddit, and every transaction was proven all the way to Bitcoin and Ethereum.
Reddit Scaling on Ethereum

Decentralization

Solutions should not depend on any single third-party provider. We prefer solutions that do not depend on specific entities such as Reddit or another provider, and solutions with no single point of control or failure in off-chain components but recognize there are numerous trade-offs to consider
Dragonchain’s architecture calls for a hybrid approach. Private business nodes hold the sensitive data while the validation and verification of transactions for the business are decentralized within seconds and secured to public blockchains within 10 minutes to 2 hours. Nodes could potentially be controlled by owners of individual subreddits for more organic decentralization.
  • Billing is currently centralized - there is a path to federation and decentralization of a scaled billing solution.
  • Operational multi-cloud
  • Operational on-premises capabilities
  • Operational deployment to any datacenter
  • Over 700 independent Community Verification Nodes with proof of ownership
  • Operational Interchain (Interoperable to Bitcoin, Ethereum, and Ethereum Classic, open to more)

Usability Scaling solutions should have a simple end user experience.

Users shouldn't have to maintain any extra state/proofs, regularly monitor activity, keep track of extra keys, or sign anything other than their normal transactions
Dragonchain and its customers have demonstrated extraordinary usability as a feature in many applications, where users do not need to know that the system is backed by a live blockchain. Lyceum is one of these examples, where the progress of academy courses is being tracked, and successful completion of courses is rewarded with certificates on chain. Our @Save_The_Tweet bot is popular on Twitter. When used with one of the following hashtags - #please, #blockchain, #ThankYou, or #eternalize the tweet is saved through Eternal to multiple blockchains. A proof report is available for future reference. Other examples in use are DEN, our decentralized social media platform, and our console, where users can track their node rewards, view their TIME, and operate a business node.
Examples:

Transactions complete in a reasonable amount of time (seconds or minutes, not hours or days)
All transactions are immediately usable on chain by the system. A transaction begins the path to decentralization at the conclusion of a 5-second block when it gets distributed across 5 separate community run nodes. Full decentralization occurs within 10 minutes to 2 hours depending on which interchain (Bitcoin, Ethereum, or Ethereum Classic) the transaction hits first. Within approximately 2 hours, the combined hash power of all interchained blockchains secures the transaction.

Free to use for end users (no gas fees, or fixed/minimal fees that Reddit can pay on their behalf)
With transaction pricing as low as $0.0000025 per transaction, it may be considered reasonable for Reddit to cover transaction fees for users.
All of Reddit's Transactions on Blockchain (month)
Community points can be earned by users and distributed directly to their Reddit account in batch (as per Reddit minting plan), and allow users to withdraw rewards to their Ethereum wallet whenever they wish. Withdrawal fees can be paid by either user or Reddit. This model has been operating inside the Dragonchain system since 2018, and many security and financial compliance features can be optionally added. We feel that this capability greatly enhances user experience because it is seamless to a regular user without cryptocurrency experience, yet flexible to a tech savvy user. With regard to currency or token transactions, these would occur on the Reddit network, verified to BTC and ETH. These transactions would incur the $0.0000025 transaction fee. To estimate this fee we use the monthly active Reddit users statista with a 60% adoption rate and an estimated 10 transactions per month average resulting in an approximate $720 cost across the system. Reddit could feasibly incur all associated internal network charges (mining/minting, transfer, burn) as these are very low and controllable fees.
Reddit Internal Token Transaction Fees

Reddit Ethereum Token Transaction Fees
When we consider further the Ethereum fees that might be incurred, we have a few choices for a solution.
  1. Offload all Ethereum transaction fees (user withdrawals) to interested users as they wish to withdraw tokens for external use or sale.
  2. Cover Ethereum transaction fees by aggregating them on a timed schedule. Users would request withdrawal (from Reddit or individual subreddits), and they would be transacted on the Ethereum network every hour (or some other schedule).
  3. In a combination of the above, customers could cover aggregated fees.
  4. Integrate with alternate Ethereum roll up solutions or other proposals to aggregate minting and distribution transactions onto Ethereum.

Bonus Points

Users should be able to view their balances & transactions via a blockchain explorer-style interface
From interfaces for users who have no knowledge of blockchain technology to users who are well versed in blockchain terms such as those present in a typical block explorer, a system powered by Dragonchain has flexibility on how to provide balances and transaction data to users. Transactions can be made viewable in an Eternal Proof Report, which displays raw data along with TIME staking information and traceability all the way to Bitcoin, Ethereum, and every other Interchained network. The report shows fields such as transaction ID, timestamp, block ID, multiple verifications, and Interchain proof. See example here.
Node payouts within the Dragonchain console are listed in chronological order and can be further seen in either Dragons or USD. See example here.
In our social media platform, Dragon Den, users can see, in real-time, their NRG and MTR balances. See example here.
A new influencer app powered by Dragonchain, Raiinmaker, breaks down data into a user friendly interface that shows coin portfolio, redeemed rewards, and social scores per campaign. See example here.

Exiting is fast & simple
Withdrawing funds on Dragonchain’s console requires three clicks, however, withdrawal scenarios with more enhanced security features per Reddit’s discretion are obtainable.

Interoperability Compatibility with third party apps (wallets/contracts/etc) is necessary.
Proven interoperability at scale that surpasses the required specifications. Our entire platform consists of interoperable blockchains connected to each other and traditional systems. APIs are well documented. Third party permissions are possible with a simple smart contract without the end user being aware. No need to learn any specialized proprietary language. Any code base (not subsets) is usable within a Docker container. Interoperable with any blockchain or traditional APIs. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js. Please see our source code and API documentation.

Scaling solutions should be extensible and allow third parties to build on top of it Open source and extensible
APIs should be well documented and stable

Documentation should be clear and complete
For full documentation, explore our docs, SDK’s, Github repo’s, architecture documents, original Disney documentation, and other links or resources provided in this proposal.

Third-party permissionless integrations should be possible & straightforward Smart contracts are Docker based, can be written in any language, use full language (not subsets), and can therefore be integrated with any system including traditional system APIs. Simple is better. Learning an uncommon or proprietary language should not be necessary.
Advanced knowledge of mathematics, cryptography, or L2 scaling should not be required. Compatibility with common utilities & toolchains is expected.
Dragonchain business nodes and smart contracts leverage Docker to allow the use of literally any language or executable code. No proprietary language is necessary. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js.

Bonus

Bonus Points: Show us how it works. Do you have an idea for a cool new use case for Community Points? Build it!

TIME

Community points could be awarded to Reddit users based upon TIME too, whereas the longer someone is part of a subreddit, the more community points someone naturally gained, even if not actively commenting or sharing new posts. A daily login could be required for these community points to be credited. This grants awards to readers too and incentivizes readers to create an account on Reddit if they browse the website often. This concept could also be leveraged to provide some level of reputation based upon duration and consistency of contribution to a community subreddit.

Dragon Den

Dragonchain has already built a social media platform that harnesses community involvement. Dragon Den is a decentralized community built on the Dragonchain blockchain platform. Dragon Den is Dragonchain’s answer to fake news, trolling, and censorship. It incentivizes the creation and evaluation of quality content within communities. It could be described as being a shareholder of a subreddit or Reddit in its entirety. The more your subreddit is thriving, the more rewarding it will be. Den is currently in a public beta and in active development, though the real token economy is not live yet. There are different tokens for various purposes. Two tokens are Lair Ownership Rights (LOR) and Lair Ownership Tokens (LOT). LOT is a non-fungible token for ownership of a specific Lair. LOT will only be created and converted from LOR.
Energy (NRG) and Matter (MTR) work jointly. Your MTR determines how much NRG you receive in a 24-hour period. Providing quality content, or evaluating content will earn MTR.

Security. Users have full ownership & control of their points.
All community points awarded based upon any type of activity or gift, are secured and provable to all Interchain networks (currently BTC, ETH, ETC). Users are free to spend and withdraw their points as they please, depending on the features Reddit wants to bring into production.

Balances and transactions cannot be forged, manipulated, or blocked by Reddit or anyone else
Users can withdraw their balance to their ERC20 wallet, directly through Reddit. Reddit can cover the fees on their behalf, or the user covers this with a portion of their balance.

Users should own their points and be able to get on-chain ERC20 tokens without permission from anyone else
Through our console users can withdraw their ERC20 rewards. This can be achieved on Reddit too. Here is a walkthrough of our console, though this does not show the quick withdrawal functionality, a user can withdraw at any time. https://www.youtube.com/watch?v=aNlTMxnfVHw

Points should be recoverable to on-chain ERC20 tokens even if all third-parties involved go offline
If necessary, signed transactions from the Reddit system (e.g. Reddit + Subreddit) can be sent to the Ethereum smart contract for minting.

A public, third-party review attesting to the soundness of the design should be available
To our knowledge, at least two large corporations, including a top 3 accounting firm, have conducted positive reviews. These reviews have never been made public, as Dragonchain did not pay or contract for these studies to be released.

Bonus points
Public, third-party implementation review available or in progress
See above

Compatibility with HSMs & hardware wallets
For the purpose of this proposal, all tokenization would be on the Ethereum network using standard token contracts and as such, would be able to leverage all hardware wallet and Ethereum ecosystem services.

Other Considerations

Minting/distributing tokens is not performed by Reddit directly
This operation can be automated by smart contract on Ethereum. Subreddits can if desired have a role to play.

One off point burning, as well as recurring, non-interactive point burning (for subreddit memberships) should be possible and scalable
This is possible and scalable with interaction between Dragonchain Reddit system and Ethereum token contract(s).

Fully open-source solutions are strongly preferred
Dragonchain is fully open source (see section on Disney release after conclusion).

Conclusion

Whether it is today, or in the future, we would like to work together to bring secure flexibility to the highest standards. It is our hope to be considered by Ethereum, Reddit, and other integrative solutions so we may further discuss the possibilities of implementation. In our public demonstration, 256 million transactions were handled in our operational network on chain in 24 hours, for the low cost of $25K, which if run today would cost $625. Dragonchain’s interoperable foundation provides the atmosphere necessary to implement a frictionless community points system. Thank you for your consideration of our proposal. We look forward to working with the community to make something great!

Disney Releases Blockchain Platform as Open Source

The team at Disney created the Disney Private Blockchain Platform. The system was a hybrid interoperable blockchain platform for ledgering and smart contract development geared toward solving problems with blockchain adoption and usability. All objective evaluation would consider the team’s output a success. We released a list of use cases that we explored in some capacity at Disney, and our input on blockchain standardization as part of our participation in the W3C Blockchain Community Group.
https://lists.w3.org/Archives/Public/public-blockchain/2016May/0052.html

Open Source

In 2016, Roets proposed to release the platform as open source to spread the technology outside of Disney, as others within the W3C group were interested in the solutions that had been created inside of Disney.
Following a long process, step by step, the team met requirements for release. Among the requirements, the team had to:
  • Obtain VP support and approval for the release
  • Verify ownership of the software to be released
  • Verify that no proprietary content would be released
  • Convince the organization that there was a value to the open source community
  • Convince the organization that there was a value to Disney
  • Offer the plan for ongoing maintenance of the project outside of Disney
  • Itemize competing projects
  • Verify no conflict of interest
  • Preferred license
  • Change the project name to not use the name Disney, any Disney character, or any other associated IP - proposed Dragonchain - approved
  • Obtain legal approval
  • Approval from corporate, parks, and other business units
  • Approval from multiple Disney patent groups Copyright holder defined by Disney (Disney Connected and Advanced Technologies)
  • Trademark searches conducted for the selected name Dragonchain
  • Obtain IT security approval
  • Manual review of OSS components conducted
  • OWASP Dependency and Vulnerability Check Conducted
  • Obtain technical (software) approval
  • Offer management, process, and financial plans for the maintenance of the project.
  • Meet list of items to be addressed before release
  • Remove all Disney project references and scripts
  • Create a public distribution list for email communications
  • Remove Roets’ direct and internal contact information
  • Create public Slack channel and move from Disney slack channels
  • Create proper labels for issue tracking
  • Rename internal private Github repository
  • Add informative description to Github page
  • Expand README.md with more specific information
  • Add information beyond current “Blockchains are Magic”
  • Add getting started sections and info on cloning/forking the project
  • Add installation details
  • Add uninstall process
  • Add unit, functional, and integration test information
  • Detail how to contribute and get involved
  • Describe the git workflow that the project will use
  • Move to public, non-Disney git repository (Github or Bitbucket)
  • Obtain Disney Open Source Committee approval for release
On top of meeting the above criteria, as part of the process, the maintainer of the project had to receive the codebase on their own personal email and create accounts for maintenance (e.g. Github) with non-Disney accounts. Given the fact that the project spanned multiple business units, Roets was individually responsible for its ongoing maintenance. Because of this, he proposed in the open source application to create a non-profit organization to hold the IP and maintain the project. This was approved by Disney.
The Disney Open Source Committee approved the application known as OSSRELEASE-10, and the code was released on October 2, 2016. Disney decided to not issue a press release.

Dragonchain Foundation

The Dragonchain Foundation was created on January 17, 2017. https://den.social/l/Dragonchain/24130078352e485d96d2125082151cf0/dragonchain-and-disney/

Update and Few Thoughts, a (Well-Typed) transcript: Liza&Charles the marketeers, Voltaire kick-off, PrisM and Ebb-and-Flow to fuck ETH2.0 Gasper, the (back)log of a man and a falcon, lots of companies, September Goguen time, Basho, 2021 Titans, Basho, Hydra and much more thoughts and prayers

Hi everybody this is Charles Hoskinson broadcasting live from warm sunny Colorado. I'm trying a new streaming service and it allows me to annotate a few things and simulcast to both periscope and youtube. Let's see how this works. I also get to put a little caption. I think for the future, I'm just for a while going to put: "I will never give away ada". So, when people repost my videos for giveaway scams they at least have that. First off, a thank you, a community member named Daryl had decided to carve a log and give his artistic impression of my twitter profile picture of me and the falcon so that always means a lot when I get these gifts from fans and also I just wanted to, on the back of the Catalyst presentation, express my profound gratitude and excitement to the community.
You know it's really really cool to see how much progress has been made in such a short period of time. It was only yesterday when we were saying "when Shelley"? Now Shelley's out and it's evolving rapidly. Voltaire is now starting to evolve rapidly and we're real close to Goguen. At the end of this month we'll be able to talk around some of the realities of Goguen and some of the ideas we have and give some dates for certain things and give you a sense of where that project is at. The good news is that we have gained an enormous amount of progress and knowledge about what we need to do and how to get that done and basically people are just executing and it's a much smaller task than getting us to Shelley. With Byron to Shelley we literally had to build a completely new cryptocurrency from the ground up. We had to have new ledger rules, new update system, we had to invent a way of transitioning from one system to another system and there's hundreds of other little innovations along the way: new network stack and so forth. Byron cosmetically looks like Shelley but under the hood it's completely different and the Shelley design was built with a lot of the things that we needed for Goguen in mind. For example, we built Shelley with the idea of extended UTXO and we built Shelley understanding what the realities were for the smart contract model and that's one of the advantages you get when you do this type of bespoke engineering. There's two consequences to that, one, the integration is significantly easier, and two, the integration is significantly faster. We won't look at that same complexity there.
The product update at the end of the month... We'll really start discussing around some of these things as well as talk about partners and talk about how the development ecosystem is going to evolve. There are a lot of threads throughout all three organizations that are happening simultaneously. Emurgo, they're really thinking deeply about DeFi and they've invited us to collaborate with them on things like stablecoins for example but we're also looking at oracles (oracle pools), DEX and these other things and because there are already people in market who have made mistakes, learned lessons, it gives us the benefit of hindsight. It means we can be much faster to market and we can build much more competitive things in market and the Cardano community gets first access to these next generation DeFi applications without a lot of the problems of the prior generations and that's super beneficial to us.
You know, the other side of it, is that Voltaire is going to have a systemic influence not just on community funding but also the overall evolution and direction of the platform. The longer it exists the more pervasive it will become. Probably first applied towards the Cardano foundation roadmap but later on it will definitely have a lot of influence and say over every element aspect of the system including the launch dApps and these other things. Basically, long term, the types of problems that Cardano solves so that's incredibly appealing to me and very exciting to me because it's like I have this giant community brain with the best and brightest of all of you working with us to get us where we need to go.
You know, another thing that was super encouraging, it's a small thing, but it shows us that we're definitely in the right direction was that we recently got a demo from Pramod (Viswanath) and his team out of university of Illinois on a protocol they create called PrisM which is a super fast proof-of-work protocol and they wrote this beautiful paper and they wrote code along with it that showed that PrisM is a ten thousand times faster than Nakamoto consensus. If you take the bitcoin proof-of-work protocol, you strip it out, you put PrisM in, you can run the entire bitcoin system 10000 times faster. They have these beautiful benchmarks to show that. Even in bad network conditions. (I'm) promoting this team, they're, they're real researchers, and they're real engineers, they use a lot of cool HPC concepts like springboarding and other things like that to accommodate that. Then I asked him in the presentation, I said well, how much faster if you replay the Ethereum chain? He says, well, that it takes a big performance hit, could be only maybe a hundred times because that model is not as easy to optimize and shard with standard computer science concepts. In fact in some cases there are limitations there that really can't be overcome. It turns out that we're more on that UTXO side than we are on the account side. As a coincidence or intent of the design of extended UTXO we're gonna have a lot easier time getting much higher performance where and when it's necessary.
I also approved this week a scaling up of the Basho project. In particular, to build a hydra prototype team. The science has gotten to a point where we can make a really competitive push in that particular direction. What does that mean? It means that in just a few short months we can de-risk technological approaches that long-term will give us a lot of fruit where and when the community decides that they need infrastructure like hydra. Now, here's the beautiful thing about hydra. If you watch my whiteboard back in September of 2017 when Cardano first hit market with Byron I talked about this concept of looking at scalability with a very simple test which is as you get more people in the system it stays at the same performance or it gets faster. We all experience systems that do this, for example, bittorrent, more people downloading something you tend to be able to get it faster and we all experience the converse which is, the system gets slower when you get more people. What does this mean? It means that hydra is an actual approach towards true scalability in the system and it's a lot easier to do than sharding even though we have a beautiful approach to get the sharding on the ledger side if we truly desire to go down that way. There's beautiful ideas that we are definitely in deep discussions about. That's a very complex thing. There was recently a paper ("Ebb-and-Flow Protocols: A Resolution of the Availability-Finality Dilemma") out of Stanford that showed that the Gasper protocol as proposed for ETH2.0 does have some security concerns and it's going to be the burden on the shoulders of the Ethereum 2.0 developers and Vitalik to address those concerns from those Stanford professors. Whenever you have these very complex protocols they have so many different ways they can break and things can go wrong so it's much more appealing when you don't have to embrace complexity to achieve the same. The elegance of hydra is that stake pool operators are very natural parties to put hydra channels on and every time we add one we get much more performance out of that and the system as it gets more valuable. The k factor increases which means you get more stake pull operators, which means you get more hydra channels, so with growth we get appreciation, with appreciation we get more decentralization, with more decentralization we get more performance. In essence, this spiritually speaking, is really what we meant when we said scalability. That the system will always grow to meet its particular needs and we have a very elegant way of moving in that direction that doesn't require us to embrace very sophisticated techniques. It's not to say that these techniques don't have a place and purpose but it says that the urgency of implementing these is gone and we then have the luxury to pick the best science when it's ready instead of rushing it to market to resolve a crisis of high fees. We'll never have that crisis so there's a beauty to Cardano that is missing, I in my view, from many cryptocurrencies and blockchains in the marketplace and we're now seeing that beauty shine through. Not only through our community who are so passionate and amazing but in the science and the engineering itself and how easy it is for us to navigate the concepts. How easy it is for us to add more things, to take some things away, to clean some things up here and there and our ability to move through.
I never imagined when in 2015 I signed up to go in on this crazy ride and try to build a world financial operating system we would have made as much progress as we made today. We've written more than 75 research papers as an organization many of which are directly applicable to Cardano. We've got great partners who work with Nasa and Boeing and Pfizer, massive companies, that have 10 years of history and millions of users to come in and help us grow better. We've worked with incredible organizations, major universities like university of Wyoming, university of Edinburgh, Tokyo, tech professors all across the world. We've worked with incredible engineering firms like VacuumLabs and AtixLabs and Twig and Well-Typed, runtime verification, QuviQ and dozens of others along the years and despite the fact that at times there's been delays and friction throughout this entire journey we've mostly been aligned and we keep learning and growing. It gives me so much hope that our best days are ahead of us and an almost fanatical belief that success is inevitable in a certain respect. You see because we always find a way to be here tomorrow and we always find a way to make tomorrow a better day than today and as long as that's the trend you're monotonically increasing towards a better tomorrow, you're always going to have that outcome, you're always going to be in a position where Cardano shines bright. Towards the end of the month we'll have a lot more to say about the development side and that'll be a beginning just like Voltaire is the beginning and then suddenly you now notice the beautiful parallelism of the roadmap. Shelley continues to evolve, partial delegation is coming, in fact, I signed the contract with vacuumlabs to bring that to Ledger (and Trezor). The Daedalus team is hard at work to make that feature apparent for everyone as is the Yoroi team.
You see that, with now Voltaire, and soon was Goguen, and these are not endpoints, rather they're just beginnings and they're never over. We can always make staking better, more diverse, more merit-based and entertain different control models, have better delegation mechanics, have better user experience. The same for smart contracts, that's an endless river and along the way what we've discovered is it's easy for us to work with great minds and great people. For example with testing of smart contracts I would love to diversify that conversation above and beyond what we can come up with and bring in some firms who have done this for a long time to basically take that part with us shoulder to shoulder and build beautiful frameworks to assist us. For example, runtime verification is doing this with, the EVM with a beautiful project called Firefly to replace Truffle. I believe that we can achieve similar ends with Plutus smart contracts.
When you ask yourself what makes a system competitive in the cryptocurrency space? In my view there are four dimensions and you have to have a good story for all four of those dimensions. You need security and correctness. A lot of people don't prioritize that but when they get that wrong it hurts retail people, it hurts everyday people, billions of dollars have been lost due to the incompetence and ineptitude of junior developers making very bad mistakes and oftentimes those developers faced no consequences. The people who lost money were innocent people who believed in cryptocurrencies and wanted to be part of the movement but didn't protect themselves adequately. That's a really sad thing and it's unethical to continue pushing a model that that is the standard or the likely outcome rather than a rare edge case. You have to as a platform, a third generation platformn invest heavily in giving the developers proper tools to ensure security and correctness. We've seen a whole industry there's been great innovations out of Quantstamp and ConsenSys and dozens of other firms in the space including runtime verification who have really made major leaps in the last few years of trying to improve that story. What's unique to Cardano is that we based our foundations on languages that were designed right the first time and there's over 35 years of history for the approach that we're following in the Haskell side that allows us to build high assurance systems and our developers in the ecosystem to build high assurance systems. We didn't reinvent the wheel, we found the best wheel and we're giving it to you.
I think we're going to be dominant in that respect as we enter 2021. Second, you look at things like ease of maintenance, ease of deployment, the life cycle of the software upgrades to the software and as we've demonstrated with things like the hard fork combinator and the fact that Voltaire is not just a governance layer for ada and Cardano but will eventually be reusable for any dApp deployed on our system. You have very natural tooling that's going to allow people to upgrade their smart contracts, their dApps and enable governance for their users at an incredibly low cost and not have to reinvent the governance wheel each and every application. This is another unique property to our system and it can be reused for the dApps that you deploy on your system as I've mentioned before. Performance is a significant concern and this was often corrupted by marketers especially ICO marketers who really wanted to differentiate (and) say: "our protocol tested on a single server in someone's basement is 500000 transactions per second" and somehow that translates to real life performance and that's antithetical to anyone who's ever to study distributed systems and understands the reality of these systems and where they go and what they do and in terms of performance. I think we have the most logical approach. You know, we have 10 years of history with bitcoin, it's a massive system, we've learned a huge amount and there's a lot of papers written about, a lot of practical projects and bitcoin is about to step into the world of smart contracts. We congratulate them on getting Schnorr sigs in and the success of Taproot. That means entering 2021, 2022, we are going to start seeing legitimate dApps DeFi projects, real applications, instead of choosing Ethereum or Algorand, EOS, Cardano, choosing bitcoin and they're adding a lot to that conversation. I think that ultimately that model has a lot of promise which is why we built a better one. There are still significant limitations with what bitcoin can accomplish from settlement time to the verbosity of contracts that can be written.
The extended UTXO model was designed to be the fastest accounting and most charitable accounting model ever, on and off chain, and hydra was designed to allow you to flex between those two systems seamlessly. When you look at the foundations of where we're at and how we can extend this from domain specific languages, for domain experts, such as Marlowe to financial experts, and the DSLs that will come later, for others, like lawyers and supply chain experts in medical databases and so forth and how easy it is to write and deploy these. Plutus being beautiful glue code for both on and off chain communications. I think we have an incredibly competitive offering for performance and when hydra comes, simply put, there'll be no one faster. If we need to shard, we're going to do that and definitely better than anybody else because we know where our security model sits and there won't be surprise Stanford papers to blindside us that require immediate addressing.
In terms of operating costs, this is the last component, in my view, and that's basically how much does it cost you the developer to run your application? There are really two dimensions, one is predictability and the other is amount. It's not just good enough to say: it's a penny per transaction today. You need to know that after you spend millions of dollars and months or years of effort building something and deploying something that you're not going to wake up tomorrow and now it's five dollars to do what used to cost a penny. You need that cost to be as low as possible and as predictable as possible and again the way that we architectured our system and as we turn things on towards the end of this year and as we enter into the next year we believe we have a great approach to achieve low operating cost. One person asks why Cardano? Well because we have great security and correctness in the development experience and tools with 35 years of legacy that were built right the first time and don't put the burdens of mistakes on your customers. They ask why Cardano and we say: well the chain itself is going to give you great solutions with identity value transformation and governance itself and as a consequence when you talk about upgrading your applications having a relationship with your customers of your applications and you talk about the ease of maintenance of those applications. There's going to be a good story there and we have beautiful frameworks like Voltaire that allow that story to evolve and we keep adding partners and who have decades of experience to get us along. We won't stop until it's much better. They asked why Cardano? We said because at the moment we're 10 times faster today than Ethereum today and that's all we really need for this year and next year to be honest and in the future we can be as fast as we need to be because we're truly scalable. As the system gets more decentralized the system improves performance and where and when we need to shard we can do that. We'll have the luxury of time to do it right, the Cardano way, and when people ask why Cardano? Because the reality is, it's very cheap to do things on our platform and the way we're building things. That's going to continue being the case and we have the governance mechanisms to allow the community to readjust fees and parameters so that it can continue being affordable for users. Everything in the system will eventually be customizable and parameterizable: from block size, to transaction fees and the community will be in a good position to dynamically allocate these things where and when needed so that we can enjoy as an ecosystem predictability in our cost.
In the coming weeks and months, especially in my company, we're going to invest a lot of time and effort into comparison marketing and product marketing. When I see people say, oh well, you've launched proof of stake, a lot of other people have done. I don't think those people fully appreciate the magnitude of what we actually accomplished as an ecosystem and the quality of the protocols that are in distribution. That's not their fault, it's our fault, because we didn't take the time in simplistic terms, not scientific papers and deep code and formal specifications, but rather everyday language, to really show why we're different. I admit that that's a product failing and that needs to be corrected so we hired a great marketing director, named Liza (Horowitz?) and she is going to work full time with me and others in the ecosystem, a great team of people, every single day to get out there and explain what we have done is novel, unique, competitive and special to our industry. Everything from Ouroboros and contrast to major other protocols from the EOSes and Algorands and the Tezos of the world. Why we're different, trade-offs we chose over them, to our network stack, to the extended UTXO model, to Plutus, to Marlowe and we're going to keep hammering away at that until we get it right and everybody acknowledges and sees what has been accomplished.
I've spent five years of my life, good years of my life, and missed a lot to get this project where it needs to go. All of our employees have invested huge sums of their personal lives, their time, their brand, their careers, in trying to make this the really most magical and special cryptocurrency and blockchain infrastructure around. No one ever signed up in this company or the other companies working on Cardano to work on a mediocre protocol. That's just another blockchain, they signed up to change the world, they signed up to build a system that legitimately can look at you in the face and say: one day we have the potential to have a billion users! That's what they signed up for and they showed up to play. They built technology that evolves in that direction with some certainty and great foundations and we have an obligation to market in a way that can show the world why, succinctly, with clarity. Understandably, this has been a failing in the past but you know what? You can always be better tomorrow that monotonically increasing make it better and that's what we're going to do. We recognized it and we're going to invest in it and with Voltaire if we can't do it. You the community can do it and we'll work with you. If you can do a better job and the funding will be there to get that done. In addition to this, we think about 2021 and we ask where does the future take us? I've thought a lot about this you know I've thought a lot about how do we get the next five years as we close out 2020 and here's the reality: we're not going to leave as a company until we have smart contracts and multi-asset and Voltaire has evolved to a point where the community can comfortably make decisions about the future of the protocol and that the staking experience has solidified and it's stable.
I don't care if this costs me millions or tens of millions of dollars out of my own pocket to make happen. I'm going to do that because that's my commitment to you, the community and every product update will keep pushing our way there. We'll continue to get more transparent, we'll continue to get more aggressive and hire more and parallelize more. Aware when we can, to deliver that experience so that Cardano gets where it needs to go. Then when we ask about where do we go next? The reality is that the science as an industry, the engineering as an industry has given a menu of incredibly unique attractive and sexy things that we can pursue. What we're going to do is work with the community and the very same tools that are turning on today, the Voltaire tools, the cardano.ideascale.com tools and we're going to propose a consortium and we're going to bring the best and brightest together and give a vision of where we can take the system in another five years. With the benefit of hindsight, massively improved processes, better estimation capabilities and the fact that we're not starting with two people at IOG. We're starting with 250 people and the best scientific division in our industry and the legacy of almost, nearly by the end of this year, 100 scientific papers. That's us, you know what, there's dozens of companies throughout the history who have worked on Cardano. It's about time to scale them up too and get client diversity. So come next year when the protocol has evolved to the point where it's ready for it, we'll have that conversation with you the community and that's going to be a beautiful conversation. At the conclusion of it, there's going to be certainty of how we're going to evolve over the next five years to get ourselves beyond the cryptocurrency space. I'm very tired of these conversations we have about: are you going to go to (coindesk's) consensus or not? Or who's going to be the big winner? What about Libra or what about this particular regulation and this crypto unicorn and this thing?
You know I've been in the space a long time and I've noticed that people keep saying the same things year after year in the same venues. Yes, the crowd sizes get larger and the amount of value at risk gets larger but I haven't seen a lot of progress in the places where I feel it is absolutely necessary for this technology to be permanent in the developing world. We need to see economic identity. People often ask what is the mission for Cardano? For us IOG, you look at economic identity and you take a look at a roadmap. For it, you scale up and down, and each and every step along the way, from open data, to self-sovereign identity, to financial inclusion. You can keep going down: to decentralized lending, decentralized insurance, decentralized banking. Each and every step along the way to economic identity. When you admit a blockchain tells you that, there's a collection of applications and infrastructure that you need to build.
My life's work is to get to a point where we have the technology to do that. The infrastructure to do that, with principles, and so we'll keep evolving Cardano and we'll keep evolving the space as a whole and the science as a whole until I can wake up and say: each box and that road to economic identity, for all people not just one group, we have a solution for that. I'm going to put those applications on Cardano and success for me is not about us being king of the crypto hill and having a higher market cap than bitcoin or being entrepreneur of the year coindesk's most influential person. It's meaningless noise, success for me is reflecting back at the things that we have accomplished together and recognizing that millions if not billions now live in a system where they all matter, they all have a voice, they all have an equal footing. The Jeff Bezos of the world have the very same experience as the person born in Rwanda and we're not done until that's the case. It's a long road, it's a hard road, but you know what? We're making progress, we have great people in Africa, we have great people in eastern Europe, we have great people in southeast Asia and great partners all along the way. Great people, Latin America, great people in south America, great people here in the United States.
When we talk about economic identity there are millions, if not tens of millions of Americans who don't have it. Same for Canadians, hundreds of thousands, who don't have it. Developed western cultures, it's the greatest blind spot of policy and as we enter into a depression as a result of coronavirus, add millions if not tens of millions more onto that list. Generations are being disenfranchised by this legacy system and we as an ecosystem, we as an entire community are offering a different way forward. Not hyper centralizationn not social credit but a way forward where you own your own money, your own identity, your own data. You're not a victim of surveillance capitalism, you're not a victim of civil asset forfeiture. When you say the wrong things, you get shut out of society. Each and every human being matters and I'm optimistic to believe that when you remind people that they matter they're gonna rise to the occasion. That is the point of my company. In the things that we do each and every day, that's our mission to give the platforms to the world so that those who don't have economic identity can get it and they can keep it and no one can take it from them and they can enjoy an ever increasing growth of standard of living wealth and prosperity.
However you want to measure that this is my goal post, I couldn't care less about the cryptocurrency space. It was a great place to start but the space needs to be reminded why it exists. Bitcoin was given a mandate on the back of the 2008 financial crisis to do something different. It was not given a mandate to go be a new settlement layer for central banks or a new way for the old guard to make more money and banks get bigger and for those who are in control to preserve their power. The whole point of doing something so crazy as to buy a coin that doesn't even exist in real life, that's just a bunch of numbers in the cloud, the whole point of that was so that we as a society could do something different than the way that we'd been doing things before. So, each and every member of the cryptocurrency space needs to remind everyone else from time to time why we're here and where did we come from and where are we going to go.
The beauty of Cardano is we have already achieved for the most part a decentralized brain and that momentum is pushing harder than ever. More and more scientists are waking up, more and more institutions are waking up, getting us there. The code we have, the right approach and I think we have a great competitive offering for 2021 as we go and battle the titans and that's going to be a lot of fun but we know who we are and where we're going and we're in the right places. It's so incredibly encouraging to see the stake pool operators not just be from California or Texas or New York or Canada. To see a lot of stake pool operators from the place that need the most, help everybody does matter and it means a lot to me for the people who are there but it means a lot to everybody to say that we have created an equal platform. It makes the participation of all of us so much more meaningful. We're not just talking to each other, we're talking to the world and by working together on this platform we're lifting the world up and giving people hope. That's the point, there's a lot more to do, we didn't get everything done. You never do you aspire, you work hard, you set a moon, shot and sometimes you can just get to orbit with the first go but you know what? When you build the next rocket you can go to Mars.
Thank you all for being with me, thank you all for being part of this. Today was a damn good day with the announcement of Voltaire. Go to cardano.ideascale.com. You can participate in that, so end of September is going to be a good day too. There's a lot of good days to come, in between a lot of hard days, doing tasks sometimes entirely forgettable but always necessary to keep the revolution going and the movement going. I cannot wait for 2021, our best days are ahead of us, because of you. You all take care now .

Syscoin Platform’s Great Reddit Scaling Bake-off Proposal

Syscoin Platform’s Great Reddit Scaling Bake-off Proposal

https://preview.redd.it/rqt2dldyg8e51.jpg?width=1044&format=pjpg&auto=webp&s=777ae9d4fbbb54c3540682b72700fc4ba3de0a44
We are excited to participate and present Syscoin Platform's ideal characteristics and capabilities towards a well-rounded Reddit Community Points solution!
Our scaling solution for Reddit Community Points involves 2-way peg interoperability with Ethereum. This will provide a scalable token layer built specifically for speed and high volumes of simple value transfers at a very low cost, while providing sovereign ownership and onchain finality.
Token transfers scale by taking advantage of a globally sorting mempool that provides for probabilistically secure assumptions of “as good as settled”. The opportunity here for token receivers is to have an app-layer interactivity on the speed/security tradeoff (99.9999% assurance within 10 seconds). We call this Z-DAG, and it achieves high-throughput across a mesh network topology presently composed of about 2,000 geographically dispersed full-nodes. Similar to Bitcoin, however, these nodes are incentivized to run full-nodes for the benefit of network security, through a bonded validator scheme. These nodes do not participate in the consensus of transactions or block validation any differently than other nodes and therefore do not degrade the security model of Bitcoin’s validate first then trust, across every node. Each token transfer settles on-chain. The protocol follows Bitcoin core policies so it has adequate code coverage and protocol hardening to be qualified as production quality software. It shares a significant portion of Bitcoin’s own hashpower through merged-mining.
This platform as a whole can serve token microtransactions, larger settlements, and store-of-value in an ideal fashion, providing probabilistic scalability whilst remaining decentralized according to Bitcoin design. It is accessible to ERC-20 via a permissionless and trust-minimized bridge that works in both directions. The bridge and token platform are currently available on the Syscoin mainnet. This has been gaining recent attention for use by loyalty point programs and stablecoins such as Binance USD.

Solutions

Syscoin Foundation identified a few paths for Reddit to leverage this infrastructure, each with trade-offs. The first provides the most cost-savings and scaling benefits at some sacrifice of token autonomy. The second offers more preservation of autonomy with a more narrow scope of cost savings than the first option, but savings even so. The third introduces more complexity than the previous two yet provides the most overall benefits. We consider the third as most viable as it enables Reddit to benefit even while retaining existing smart contract functionality. We will focus on the third option, and include the first two for good measure.
  1. Distribution, burns and user-to-user transfers of Reddit Points are entirely carried out on the Syscoin network. This full-on approach to utilizing the Syscoin network provides the most scalability and transaction cost benefits of these scenarios. The tradeoff here is distribution and subscription handling likely migrating away from smart contracts into the application layer.
  2. The Reddit Community Points ecosystem can continue to use existing smart contracts as they are used today on the Ethereum mainchain. Users migrate a portion of their tokens to Syscoin, the scaling network, to gain much lower fees, scalability, and a proven base layer, without sacrificing sovereign ownership. They would use Syscoin for user-to-user transfers. Tips redeemable in ten seconds or less, a high-throughput relay network, and onchain settlement at a block target of 60 seconds.
  3. Integration between Matic Network and Syscoin Platform - similar to Syscoin’s current integration with Ethereum - will provide Reddit Community Points with EVM scalability (including the Memberships ERC777 operator) on the Matic side, and performant simple value transfers, robust decentralized security, and sovereign store-of-value on the Syscoin side. It’s “the best of both worlds”. The trade-off is more complex interoperability.

Syscoin + Matic Integration

Matic and Blockchain Foundry Inc, the public company formed by the founders of Syscoin, recently entered a partnership for joint research and business development initiatives. This is ideal for all parties as Matic Network and Syscoin Platform provide complementary utility. Syscoin offers characteristics for sovereign ownership and security based on Bitcoin’s time-tested model, and shares a significant portion of Bitcoin’s own hashpower. Syscoin’s focus is on secure and scalable simple value transfers, trust-minimized interoperability, and opt-in regulatory compliance for tokenized assets rather than scalability for smart contract execution. On the other hand, Matic Network can provide scalable EVM for smart contract execution. Reddit Community Points can benefit from both.
Syscoin + Matic integration is actively being explored by both teams, as it is helpful to Reddit, Ethereum, and the industry as a whole.

Proving Performance & Cost Savings

Our POC focuses on 100,000 on-chain settlements of token transfers on the Syscoin Core blockchain. Transfers and burns perform equally with Syscoin. For POCs related to smart contracts (subscriptions, etc), refer to the Matic Network proposal.
On-chain settlement of 100k transactions was accomplished within roughly twelve minutes, well-exceeding Reddit’s expectation of five days. This was performed using six full-nodes operating on compute-optimized AWS c4.2xlarge instances which were geographically distributed (Virginia, London, Sao Paulo Brazil, Oregon, Singapore, Germany). A higher quantity of settlements could be reached within the same time-frame with more broadcasting nodes involved, or using hosts with more resources for faster execution of the process.
Addresses used: 100,014

It is important to note that this POC is not focused on Z-DAG. The performance of Z-DAG has been benchmarked within realistic network conditions: Whiteblock’s audit is publicly available. Network latency tests showed an average TPS around 15k with burst capacity up to 61k. Zero-latency control group exhibited ~150k TPS. Mainnet testing of the Z-DAG network is achievable and will require further coordination and additional resources.
Even further optimizations are expected in the upcoming Syscoin Core release which will implement a UTXO model for our token layer bringing further efficiency as well as open the door to additional scaling technology currently under research by our team and academic partners. At present our token layer is account-based, similar to Ethereum. Opt-in compliance structures will also be introduced soon which will offer some positive performance characteristics as well. It makes the most sense to implement these optimizations before performing another benchmark for Z-DAG, especially on the mainnet considering the resources required to stress-test this network.

Cost Savings

Total cost for these 100k transactions: $0.63 USD
See the live fee comparison for savings estimation between transactions on Ethereum and Syscoin. Below is a snapshot at time of writing:
ETH price: $318.55 ETH gas price: 55.00 Gwei ($0.37)
Syscoin price: $0.11
Snapshot of live fee comparison chart
Z-DAG provides a more efficient fee-market. A typical Z-DAG transaction costs 0.0000582 SYS. Tokens can be safely redeemed/re-spent within seconds or allowed to settle on-chain beforehand. The costs should remain about this low for microtransactions.
Syscoin will achieve further reduction of fees and even greater scalability with offchain payment channels for assets, with Z-DAG as a resilience fallback. New payment channel technology is one of the topics under research by the Syscoin development team with our academic partners at TU Delft. In line with the calculation in the Lightning Networks white paper, payment channels using assets with Syscoin Core will bring theoretical capacity for each person on Earth (7.8 billion) to have five on-chain transactions per year, per person, without requiring anyone to enter a fee market (aka “wait for a block”). This exceeds the minimum LN expectation of two transactions per person, per year; one to exist on-chain and one to settle aggregated value.

Benefits

  • Permissionless
  • No counterparties involved
  • No trading mechanisms involved
  • No third-party liquidity providers required
  • Cross-chain Fractional Supply - 2-way peg - Token supply maintained globally
  • ERC-20s gain vastly improved transactionality with the Syscoin Token Platform, along with the security of bitcoin-core-compliant PoW.
  • SPTs gain access to all the tooling, applications and capabilities of Ethereum for ERC-20, including smart contracts.

Developer & User Diligence

Trade-off

The Syscoin Ethereum Bridge is secured by Agent nodes participating in a decentralized and incentivized model that involves roles of Superblock challengers and submitters. This model is open to participation. The benefits here are trust-minimization, permissionless-ness, and potentially less legal/regulatory red-tape than interop mechanisms that involve liquidity providers and/or trading mechanisms.
The trade-off is that due to the decentralized nature there are cross-chain settlement times of one hour to cross from Ethereum to Syscoin, and three hours to cross from Syscoin to Ethereum. We are exploring ways to reduce this time while maintaining decentralization via zkp. Even so, an “instant bridge” experience could be provided by means of a third-party liquidity mechanism. That option exists but is not required for bridge functionality today. Typically bridges are used with batch value, not with high frequencies of smaller values, and generally it is advantageous to keep some value on both chains for maximum availability of utility. Even so, the cross-chain settlement time is good to mention here.

Cost

Ethereum -> Syscoin: Matic or Ethereum transaction fee for bridge contract interaction, negligible Syscoin transaction fee for minting tokens
Syscoin -> Ethereum: Negligible Syscoin transaction fee for burning tokens, 0.01% transaction fee paid to Bridge Agent in the form of the ERC-20, Matic or Ethereum transaction fee for contract interaction.

Z-DAG

Zero-Confirmation Directed Acyclic Graph is an instant settlement protocol that is used as a complementary system to proof-of-work (PoW) in the confirmation of Syscoin service transactions. In essence, a Z-DAG is simply a directed acyclic graph (DAG) where validating nodes verify the sequential ordering of transactions that are received in their memory pools. Z-DAG is used by the validating nodes across the network to ensure that there is absolute consensus on the ordering of transactions and no balances are overflowed (no double-spends).

Benefits

  • Unique fee-market that is more efficient for microtransaction redemption and settlement
  • Uses decentralized means to enable tokens with value transfer scalability that is comparable or exceeds that of credit card networks
  • Provides high throughput and secure fulfillment even if blocks are full
  • Probabilistic and interactive
  • 99.9999% security assurance within 10 seconds
  • Can serve payment channels as a resilience fallback that is faster and lower-cost than falling-back directly to a blockchain
  • Each Z-DAG transaction also settles onchain through Syscoin Core at 60-second block target using SHA-256 Proof of Work consensus

Z-DAG White Paper
Useful read: An in-depth Z-DAG discussion between Syscoin Core developer Jag Sidhu and Brave Software Research Engineer Gonçalo Pestana

Trade-off

Z-DAG enables the ideal speed/security tradeoff to be determined per use-case in the application layer. It minimizes the sacrifice required to accept and redeem fast transfers/payments while providing more-than-ample security for microtransactions. This is supported on the premise that a Reddit user receiving points does need security yet generally doesn’t want nor need to wait for the same level of security as a nation-state settling an international trade debt. In any case, each Z-DAG transaction settles onchain at a block target of 60 seconds.

Syscoin Specs

Syscoin 3.0 White Paper
(4.0 white paper is pending. For improved scalability and less blockchain bloat, some features of v3 no longer exist in current v4: Specifically Marketplace Offers, Aliases, Escrow, Certificates, Pruning, Encrypted Messaging)
  • 16MB block bandwidth per minute assuming segwit witness carrying transactions, and transactions ~200 bytes on average
  • SHA256 merge mined with Bitcoin
  • UTXO asset layer, with base Syscoin layer sharing identical security policies as Bitcoin Core
  • Z-DAG on asset layer, bridge to Ethereum on asset layer
  • On-chain scaling with prospect of enabling enterprise grade reliable trustless payment processing with on/offchain hybrid solution
  • Focus only on Simple Value Transfers. MVP of blockchain consensus footprint is balances and ownership of them. Everything else can reduce data availability in exchange for scale (Ethereum 2.0 model). We leave that to other designs, we focus on transfers.
  • Future integrations of MAST/Taproot to get more complex value transfers without trading off trustlessness or decentralization.
  • Zero-knowledge Proofs are a cryptographic new frontier. We are dabbling here to generalize the concept of bridging and also verify the state of a chain efficiently. We also apply it in our Digital Identity projects at Blockchain Foundry (a publicly traded company which develops Syscoin softwares for clients). We are also looking to integrate privacy preserving payment channels for off-chain payments through zkSNARK hub & spoke design which does not suffer from the HTLC attack vectors evident on LN. Much of the issues plaguing Lightning Network can be resolved using a zkSNARK design whilst also providing the ability to do a multi-asset payment channel system. Currently we found a showstopper attack (American Call Option) on LN if we were to use multiple-assets. This would not exist in a system such as this.

Wallets

Web3 and mobile wallets are under active development by Blockchain Foundry Inc as WebAssembly applications and expected for release not long after mainnet deployment of Syscoin Core 4.2. Both of these will be multi-coin wallets that support Syscoin, SPTs, Ethereum, and ERC-20 tokens. The Web3 wallet will provide functionality similar to Metamask.
Syscoin Platform and tokens are already integrated with Blockbook. Custom hardware wallet support currently exists via ElectrumSys. First-class HW wallet integration through apps such as Ledger Live will exist after 4.2.
Current supported wallets
Syscoin Spark Desktop
Syscoin-Qt

Thank you for close consideration of our proposal. We look forward to feedback, and to working with the Reddit community to implement an ideal solution using Syscoin Platform!
