Come-from-BeyondToday at 5:17 AM In IoT broadcasting is enough to prove that work has been done and that requires few microseconds That technique goes under "NBPoW" codename now
Come-from-BeyondToday at 5:23 AM [Wouldn't a system like this be vulnerable to interference of non-IoT devices?] jamming is possible
Come-from-BeyondToday at 5:25 AM [where is this magical IoT land] In prototyping phase -
Come-from-BeyondToday at 5:26 AM [That's a LiFi demo, no?] yes [simply a means of sending data already in use today?] yes, but noone offered a complete IoT solution yet
Come-from-BeyondToday at 5:36 AM [So, NBPoW with LiFi, is that like PoW based on keeping the sending party light emitter occupied with sending the data as a form of proof of work?] No [jamming is possible. is that not a big problem?] Yes, and it's not solved yet. Luckily for LiFi it's much easier to see the location of the jammer.
Eric Hop [IF]Today at 3:29 AM Abra is an intermediate language that is as close to assembler as you can get while still enabling translation to wildly different architectures like x86 and fpga I am in the process of writing a document that explains the Qubic Processing Model and describes Abra as part of that. May take a little while because I want it to be coherent and understandable. The concepts involved are alien enough as it is.
Eric Hop [IF]Today at 6:28 AM I'm currently sitting with Paul discussing things and clarifying things and the conclusions we are drawing about the possibilities of Qubic are staggering. @stanley Abra is not exactly a VM. A virtual machine is usually a piece of software that can be compiled to different hardware platforms and then interprets the virtual machine code. Abra uses JIT-compilation to actually generate target machine code, including hardware like CPU, GPU, and FPGA. There is a Supervisor component, but all that one does is instantiating, loading, JIT-compiling (if necessary), and triggering the code. The Supervisor also handles the sending of events between qubics.
Eric Hop [IF]Today at 6:48 AM Mind = blown. Paul just implemented Curl hash function in Abra as a real-world example of Abra code. Took him less than an hour, and most of it was fiddling with the editor to generate the correct tables. We're trying to get a feel for the language at the moment. Can't wait for the compiler to be ready.
Eric Hop [IF]Today at 7:20 AM Abra is badass. Seriously. Paul and I are deep-diving in what it can do. While discussing it all kinds of light bulbs were going off on both sides. You know how when you have a deep discussion and try to explain what you are thinking to someone else you yourself get a deeper understanding? We've had several of these breakthrough moments within the last 24 hours.
Eric Hop [IF]Today at 7:58 AM We're cleaning up some syntax rules in Abra at the moment. Actually using it in real life highlights where we want things to be simpler to do, or more readable. Once we have that we will probably incorporate those changes and post the Abra Curl function here. Just to throw you guys a bone until we have more extensive documentation.
Eric Hop [IF]Today at 8:55 AM @Werner We have no syntax highlighting modules yet if that's what you are hoping for
Eric Hop [IF]Today at 9:09 AM Right now it looks unlike pretty much anything I have ever seen and yet it seems familiar. We're trying to use familiar constructs as much as possible, yet some things are very different, even if they look like something you already know. The code looks familiar in that you see lots of lines of assignments, array-like tables, and function definitions. It looks unfamiliar in that the usual control statements are completely missing. No if-then-else, no loops. And yet it expresses the intent in a very simple and elegant way if you understand how it works.
Eric Hop [IF]Yesterday at 11:28 PM [Will Abra have an IDE?] @Zass Initially no IDE. Use your favorite code editor or dev environment. [@Eric Hop [IF] is it possible to use AOT compilation if you were to write something in Abra and distribute it in native code?] @Rajiv Shah Distributing in native code would limit the use of the qubic to the architecture it was compiled for.
Eric Hop [IF]Today at 5:53 AM These things is literally where our community can shine. Creating syntax-highlighting for Abra in multiple dev environments. I would love an IntelliJ syntax highlighter for Abra for example.
Ralf Rottmann [IF]Yesterday at 4:05 AM There is a modified (experimental) IRI node connected to the coordinator, and this node rejected valid transactions due to some minor issues. Once we understood the root cause, we fixed the code in this version of IRI and everything is back to normal.
Eric Hop [IF]Last Friday at 10:52 AM @Ganreizu Since it is a JIT compiler compilation only needs to be done once when a qubic is instantiated and could be cached for future usage. Abra source code will be translated into intermediate trit code representation called Handy, so any translation phase will only need to load that representation of the code tree (no parsing, syntax checking, etcetera is necessary) and then can directly map that code tree to LLVM or Verilog. So it's the qubic packaging process that does the translation from Abra source code into Handy and that happens only once on the side of the qubic creator. This will allow for all kinds of handy (pun intended) tools in the future. We imagine a decompiler that can turn Handy back into Abra source code for example, or an obfuscator that can obfuscate Handy similar to how Java byte code is obfuscated. We also have ideas (very future ideas) for IDE's that can directly emit Handy, or even Evolutionary Algorithms (EA) that can generate optimal Handy trit code directly for certain applications. @empler All this will be open source code. No patents. @thebruce44 It's a functional programming language. With a few twists. Definitely a paradigm shift. But on the other hand it turns out the code is simple and elegant. It's less problematic to directly code into it than we originally anticipated.
Eric Hop [IF]Today at 2:21 AM [@Eric Hop [IF] hi Eric :nerd: do you know what's happening with exchanges?] Nope. Haven't used exchanges in a while and am too busy with Qubic.
Eric Hop [IF]Today at 3:32 AM After last week I have revised my thoughts about this. Paul and I tried to implement 2 practical applications using Abra. We implemented the old Curl function just for laughs and it was possible and surprisingly easy without excessive bootstrap steps. We then proceeded to implement a key-value store and again it was entirely possible with hardly any bootstrapping, Practical applications will definitely be possible and we will demonstrate that with a cool idea we have for our PoC. Given these encouraging results I revised our chances of having a PoC by end of year from my original personal estimate of 50/50 to 95%. This does not mean Abra has been vetted. The compiler is still under development (80%). And after the compiler is done we will still need to build the Supervisor to be able to run the code as intended. We simply wrote source code that looked as if it should do what we want it to do, just like you can do in any language as a thought experiment without compiling.

microhashYesterday at 8:38 PM i bought iota a year ago back when most people just barely knew about bitcoin and iota had just been listed on the first major exchange. i held through all the fud while iota matured from a startup to an organized foundation. lots of new partnerships, more exchange listings and now we have ixi hub and a perfectly working wallet. and yet, it's still cheaper than a year ago. if you buy now, think about it like this: you are getting what people bought a year ago back when everything was unclear. and they are getting out at a loss after holding that high risk asset for an entire year. sounds like a fucking opportunity to me.

QuarkChain Testnet 2.0 Mining.

QuarkChain Testnet 1.0 was built based on standardized blockchain system requirements, which included network, wallet, browser, and virtual machine functionalities. Other than the fact that the token was a test currency, the environment was completely compatible with the main network. By enhancing the communication efficiency and security of the network, Testnet 2.0 further improves the openness of the network. In addition, Testnet 2.0 will allow community members (other than citizens or residents of the United States) to contribute directly to the network, i.e. running a full node and mining, and receive testnet tokens as rewards.
QuarkChain Testnet 2.0 will support multiple mining algorithms, including two typical algorithms: Ethash and Double SHA256, as well as QuarkChain’s unique algorithm called Qkchash – a customized ASIC-resistant, CPU mining algorithm, exclusively developed by QuarkChain. Mining is available both on the root chain and on shards due to QuarkChain’s two-layered blockchain structure. Miners can flexibly choose to mine on the root chain with higher computing power requirements or on shards based on their own computing power levels. Our Goal By allowing community members to participate in mining on Testnet 2.0, our goal is to enhance QuarkChain’s community consensus, encourage community members to participate in testing and building the QuarkChain network, and gain first-hand experience of QuarkChain’s high flexibility and usability. During this time, we hope that the community can develop a better understanding about our mining algorithms, sharding technologies, and governance structures, etc. Furthermore, this will be a more thorough challenge to QuarkChain’s design before the launch of mainnet! Thus, we sincerely invite you to join the Testnet 2.0 mining event and build QuarkChain’s infrastructure together!
Today, we’re pleased to announce that we are officially providing the CPU mining demo to the public (other than citizens and residents of the United States)! Everyone can participate in our mining event, and earn tQKC, which can be exchanged to real rewards by non-U.S. persons after the launch of our mainnet. Also, we expect to upgrade our testnet over time, and expect to allow GPU mining for Ethash, and ASIC mining for Double SHA256 in the future. In addition, in the near future, a mining pool that is compatible with all mining algorithms of QuarkChain is also expected to be supported.
We hope all the community members can join in with us, and work together to complete this milestone! 2 Introduction to Mining Algorithms 2.1 What is mining? Mining is the process of generating the new blocks, in which the records of current transactions are added to the record of past transactions. Miners use software that contribute their mining power to participate in the maintenance of a blockchain. In return, they obtain a certain amount of QKC per block, which is called coinbase reward. Like many other blockchain technologies, QuarkChain adopts the most widely used Proof of Work (PoW) consensus algorithm to secure the network.
A cryptographically-secure PoW is a costly and time-consuming process which is difficult to solve due to computation-intensity or memory intensity but easy for others to verify. For a block to be valid it must satisfy certain requirements and hash to a value less than the current target threshold. Reverting a block requires recreating all successor blocks and redoing the work they contain, which is costly.
By running a cluster, everyone can become a miner and participate in the mining process. The mining rewards are proportional to the number of blocks mined by each individual.
2.2 Introduction to QuarkChain Algorithms and Mining setup According to QuarkChain’s two-layered blockchain structure and Boson consensus, different shards can apply different consensus and mining algorithms. As part of the Boson consensus, each shard can adjust the difficulty dynamically to increase or decrease the hash power of each shard chain.
In order to fully test QuarkChain testnet 2.0, we adopt three different types of mining algorithms” Ethash, Double SHA256, and Qkchash, which is ASIC resistant and exclusively developed by QuarkChain founder Qi Zhou. These first two hash algorithms correspond to the mining algorithms dominantly conducted on the graphics processing unit (GPU) and application-specific integrated circuits (ASIC), respectively.
I. Ethash Ethash is the PoW mining algorithm for Ethereum. It is the latest version of earlier Dagger-Hashimoto. Ethash is memory intensive, which makes it require large amounts of memory space in the process of mining. The efficiency of mining is basically independent of the CPU, but directly related to memory size and bandwidth. Therefore, by design, building Ethash ASIC is relatively difficult. Currently, the Ethash mining is dominantly conducted on the GPU machines. Read more about Ethash:
II. Double SHA256 Double SHA256 is the PoW mining algorithms for Bitcoin. It is computational intensive hash algorithm, which uses two SHA256 iterations for the block header. If the hash result is less than the specific target, the mining is successful. ASIC machine has been developed by Bitmain to find more hashes with less electrical power usage. Read more about Double SHA256:
III. Qkchash Originally, Bitcoin mining was conducted on the CPU of individual computers, with more cores and greater speed resulting in more profitability. After that, the mining process became dominated by GPU machines, then field-programmable gate arrays (FPGA) and finally ASIC, in a race to achieve more hash rates with less electrical power usage. Due to this arms race, it has become increasingly harder for prospective new miners to join. This raises centralization concerns because the manufacturers of the high-performance ASIC are concentrated in a small few.
To solve this, after extensive research and development, QuarkChain founder Dr. Qi Zhou has developed mining algorithm — Qkchash, that is expected to be ASIC-resistant. The idea is motivated by the famous date structure orders-statistic tree. Based on this data structure, Qkchash requires to perform multiple search, insert, and delete operations in the tree, which tries to break the ASIC pipeline and makes the code execution path to be data-dependent and unpredictable besides random memory-access patterns. Thus, the mining efficiency is closely related to the CPU, which ensures the security of Boston consensus and encourges the mining decentralization.
Please refer to Dr. Qi’s paper for more details:
2.3 Testnet 2.0 mining configuration Numbers of Shards: 8 Cluster: According to the real-time online mining node The corresponding mining algorithm is Read more about Ethash with Guardian:
We will provide cluster software and the demo implementation of CPU mining to the public. Miners are able to arbitrarily select one shard or multiple shards to mine according to the mining difficulty and rewards of different shards. GPU / ASIC mining is allowed if the public manages to get it working with the current testnet. With the upgrade of our testnet, we will further provide the corresponding GPU / ASIC software.
QuarkChain’s two-layered blockchain structure, new P2P mode, and Boson consensus algorithm are expected tobe fully tested and verified in the QuarkChain testnet 2.0. 3 Mining Guidance In order to encourage all community members to participate in QuarkChain Testnet 2.0 mining event, we have prepared three mining guidances for community members of different backgrounds.
Today we are releasing the Docker Mining Tutorial first. This tutorial provides a command line configuration guide for developers and a docker image for multiple platforms, including a concise introduction of nodes and mining settings. Follow the instructions here: Quick Start with QuarkChain Mining.
Next we will continue to release: A tutorial for community members who don’t have programming background. In this tutorial, we will teach how to create private QuarkChain nodes using AWS, and how to mine QKC step by step. This tutorial is expected to be released in the next few days. Programs and APIs integrated with GPU / ASIC mining. This is expected to allow existing miners to switch to QKC mining more seamlessly. Frequently Asked Questions: 1. Can I use my laptop or personal computer to mine? Yes, we will provide cluster software and the demo implementation of CPU mining to the public. Miners will be able to arbitrarily select one shard or multiple shards to mine according to the work difficulty and rewards of different shards. 2. What is the minimum requirements for my laptop or personal computer to mine? Please prepare a Linux or MacOs machine with public IP address or port forwarding set up. 3. Can I mine with my GPU or an ASIC machine? For now, we will only be providing the demo implementation of CPU mining as our first step. Interested miners/developers can rewrite the corresponding GPU / ASIC mining program, according to the JSON RPC API we provided. With the upgrade of our testnet, we expect to provide the corresponding GPU / ASIC interface at a later date. 4. What is the difference among the different mining algorithms? Which one should I choose? Double SHA256 is a computational intensive algorithm, but Ethash and Qkchash are memory intensive algorithms, which have certain requirements on the computer’s memory. Since currently we only support CPU mining, the mining efficiency entirely depends on the cores and speed of CPU. 5. For testnet mining, what else should I know? First, the mining process will occupy a computer’s memory. Thus, it is recommended to use an idle computer for mining. In Testnet 2.0 settings, the target block time of root chain is 60 seconds, and the target block time of shard chain is 10 seconds. The mining is a completely random process, which will take some time and consume a certain amount of electricity. 6. What are the risks of testnet mining? Currently our testnet is still under the development stage and may not be 100% stable. Thus, there would be some risks for QuarkChain main chain forks in testnet, software upgrades and system reboots. These may cause your tQKC or block record to be lost despite our best efforts to ensure the stability and security of the testnet.
For more technical questions, welcome to join our developer community on Discard: 4 Reward Mechanism Testnet 2.0 and all rewards described herein, including mining, are not being offered and will not be available to any citizens or residents of the United States and certain other jurisdictions.

SUQA coin currency supporting X22i algorithm

SUQA coin currency supporting X22i algorithm
I want to tell you about a currency supporting an X22i algorithm; SUQA coin. SUQA team is confident that the algorithm will be stable enough to perform mining on a quantum computer, This will primarily involve the existence of a problem such as insufficient memory, typical of such devices. In addition to the ability to implement a new mining algorithm, SUQA will also feature a high transaction rate of more 530 transactions per second at low transaction costs. This is 75 times Bitcoin.
And about ecosystem, I would say that simply by reading this article or chatting with a friend about SUQA you have already begun to experience being a part of the ecosystem. An ecosystem as it pertains to blockchain technology is everything that works together to leverage the blockchain technology towards some meaningful purpose rather that be providing a service, product, or some other utility.

[UK] Selling loads of assorted parts, 5870s, 6990, processors, motherboards, ram, psus, fpga, tablets, ...

Hi all, I am obviously new here, but have good reputation elsewhere I am quite happy to jump through any hoops that give you additional peace of mind :)
If you live near Margate, UK you are welcome to pick up in person or I will ship (even internationally) as long as you cover the shipping costs.
Got lots of stuff I don't want, the prices I'm listing are just rough guidelines, If you can find any of my stuff cheaper elsewhere I will certainly lower my price. I pretty much did a rough price guestimate using eBay listings. Things with (boxed) mean that I have the original box for them. Some stuff I havn't priced up, just make sensible offers :)
I will accept pretty much any payment method if possible, Paypal, Bitcoin, BACS Transfer, etc. Just ask! :)
Without further ado, things:
£350 - Saphire AMD 6990
£70 - 7 x XFX ATI HD 5870 1GB (boxed) 1

2 x 1GB DDR 400Mhz Adata memory 7
If you are curious about where all this stuff has been / come from, here's some history on everything :)
1) All of this stuff was purchased for bitcoin mining back in May 2011. It's all been faithfully mining in my spare bedroom since then, has turned a nice little profit, and is now a bit too slow to compete with all the other miners, so it's gotta go! photo 1 photo 2
2) These used to be the monitors I used on my main desktop. I decided to upgrade to 2560x1440 monitors, so these are now sitting in the spare bedroom not doing much. They were always great monitors though! photo
3) Used to be the power supply in my main PC, however when I upgraded to a new motherboard I could no longer fit my SLi setup in since the PSU was right up against the bottom of the board and I needed to utilise the bottom slot. Remember that this is the new CPX form factor by Antec, so you'll either need an Antec case or a hacksaw to get it to fit ;)
4) Bought this for bitcoin experimentation but never ended up using it. It got took out of the box and I looked at it, that was about it. Never been used and in the original box with all the things.
5) These are great fun especially for the price, I bought it and used it as a bedside clock for a while (Yay Ubuntu+Conky). I use my Nexus 7 to do this job now though, so this has been relegated to the cupboard. Has a green stuck pixel right on the edge of the screen. You can find lots of info about hacking them here
6) Used to use this as my fan controller but switched to a couple of BitFenix recons because I fan control in software. Looks really cool though. Shame I can't have this and software control really! :P
7) Used to be my old gaming PC, got relegated to being the home theatre PC and then got relegated to the cupboard :P, Hasn't been used in a while but I assume it all still works, will test it before I send it off.
That's all, again feel free to ask me any questions. or negotiate on the prices (especially if your ordering more than one thing). I'm on IRC (Freenode) should you want to IM me. :)

FAQ#1: Can I mine Bitcoins using this old thing I found in my closet?

If you're wondering whether or not it is feasible to mine Bitcoin using your CPU, GPU (video card), cell phone, ps3, xbox, or original 1985 NES.
The true answer to that question if you are being pedantic is: Yes, you can!
The time required to get setup initially and the electrical efficiency of the hardware in question usually deduces the same answer from economically minded people, however. Which is: No!
Bitcoin mining is a highly competitive technological arms race, and you should never bring a knife to a gun fight.
The only two types of Bitcoin miners you want to be looking at right now are:
Feel free to kindly link any newbies asking a similar question to this post and downvote their original one, you can find this post stickied in the sidebar.

KNCminer to release 350 GH/s in September

A lot has happened in the last few weeks, so we thought it was time for a new update. The main focus of this newsletter will be around the following topics:
Jupiter’s performance increase. A new product called Saturn. More information on our approach to Litecoin mining devices. Things we are working on in the next few weeks. Update of Jupiter performance We have previously announced that Jupiter will have a minimum performance of 250GH/s. We can now be a little more accurate and say that it will be above 350GH/s. A few improvements have allowed this to happen. One of them is that we are now able to use the 28nm technology in our standard ASIC design.
Delivery is also important to our customers so we can also narrow down from saying autumn to the latter part of September 2013. This is still a compressed timeline but we are very confident we can meet our deadline. (Which in terms of Standard cell ASIC design is a very aggressive time frame.) We are able to commit to this deadline because of the experience that ORSoC brings.
The last update around Jupiter is the price. We previously stated that it would be between 7000 and 8000 USD per device. The final component costs are all in and we can confirm that the price will be 6995 USD.
So to recap. Jupiter now comes with:
350 GH/s. 28nm Standard Cell ASIC chips. Shipment in September 2013. 6995 USD price tag. Announcement of Saturn We have had many people asking for a cheaper ASIC device, which would still give great value for money in terms of hashes per dollar.
So we have listened. We have created Saturn, Saturn is a 4 blade device. (Jupiter is an 8 blade device) Saturn still offers great value in terms of hash per dollar, but has a much more favorable purchase price of 3795 USD. It will have a minimum performance of 175 GH/s and because it’s based on the same modular design as Jupiter, they will ship alongside each other in September 2013.
So to recap on Saturn:
175 GH/s. 28nm Standard Cell ASIC chips. Shipment in September 2013. 3795 USD price tag.
Litecoin device A common request arriving on our desks is around us producing a Litecoin mining device. We have stated that we are looking into it, to see if we can develop a device that would make sense for the Litecoin community. What we would like to say at this stage is that we are removing things form our plate which in any way delay the shipment of our ASIC based Bitcoin mining hardware, having said that if we have any space in our resources. (Which we may increase in the near future) They are being targeted at producing a Litecoin device. So as of today it’s on the plan but is second only to the ASIC Bitcoin devices. We will continue to conduct research into Litecoin devices and see exactly how challenging it would be to produce an FPGA type setup for mining Litecoins.
The coming weeks Next week we will have a demo video of our Mars device uploaded for everyone to see. So at this point we would like to invite the community to select people to come to our offices. Those people would be able to meet the engineering team and have a look at our prototype. If you would like an invite please send us an email. We will try to accommodate as many people as we can.
Above all we would like to say thanks again for all of your feedback. Keep it coming it allows us to produce better and more targeted products.

Open-Source FPGA Bitcoin Miner and ASIC conversion...

Hey Everyone,
So there has been a lot of talk about FPGA and ASIC miners recently, and I've been doing some of my own research. FPGA's are fully programmable, and mainly used in R&D where ASIC's cannot be programmed - but are cheap and have the potential to out preform FPGA's.
Here's where it gets interesting. There are multiple companies that do FPGA-to-ASIC migrations for this exact purpose. The "R&D lab" has a stable setup with their FPGA and want to get it into production. It would make little sense to use expensive and slower FPGA's, especially when the code (HDL) has been finalized. This is where these migration companies come in...
Now this is what I'm thinking, we already have the Open-Source FPGA Bitcoin Miner HDL - so what's stopping us with going into full production mode and getting our OWN ASIC's???
I've come across multiple companies that do this (it seems pretty common practice) such as this one that even offers pin compatibility which would make our lives even easier:
Any input is welcomed! I haven't messed around with FGPA's in 13 years so I'm probably off on a few things. Feel free to fill in the holes!

Home made soldered bitcoin miner with single transistors

I have read a lot about ASIC and even FPGA systems which allow for faster mining since they are specifically designed for the bitcoin mining program. Would it be possible to create and even fastecheaper bitcoin setup with single transistors and an electronic engineering background? This would be a discrete logic circuit, on a PCB.

ASIC miners i Danmark?

Hey Bitcoin DK,
Jeg er interesseret i Bitcoin (selvom jeg dog ikke ejer en eneste BTC), men jeg kunne godt tænke mig at vide om det var muligt at købe nogle af de nye ASIC miners og bruge dem i Danmark. Det er nogle dyre, men hurtige miners som ser ud til at (i worst case scenario) at tjene sig selv ind forholdsvis hurtigt.
Hvilke setups har i haft success med? Er det måske lettere at få skaffet sig en række FPGA miners i stedet for? Kan det overhovedet betale sig at investere i miners så "sent" inde i Bitcoin ræset?

Bitcoin Utopia Press Release

Bitcoin Utopia is a crowd-donation platform that uses Internet-connected computers to mine cryptocurrencies.
Bitcoin Utopia then donates, after a fee, the cryptocurrencies for various campaigns like incentive awards and science projects.
Scientific organizations looking for funding for incentive awards and science projects might want to create a campaign on Bitcoin Utopia. Four campaigns have already been started and the successful Aquaponics setup campaign has been documented very well with lots of pictures of the gear bought with the bitcoin donations.
Bitcoin Utopia has over 3700 users and is looking for new volunteers with CPUs, GPUs, FPGAs or ASIC devices ready to mine donations for the campaigns. The instructions how to setup the mining software can be found on the campaign pages.
Bitcoin Utopia is run by a Finnish company Consultum Finland Oy Ltd.

Bitcoin mining evolves from GPU to FPGA and now custom ASIC

Bitcoin mining used to be rows of consumer gpu's brute-forcing the sha-256 encryption (max 2000 Mhash/s). After that people and companies started using expensive fpga setups to do it faster (100-25000 Mhash/s). Now companies have developed custom ASIC for bitcoin mining. (Avalon , Bitforce , Deepbit). It has an impressive speed of 4.5K -> 1500K Mhash/s . This increase of computing ability will probably put the gpu mining out of business and shake up the market abit.
Some numbers:

KNCMiner open for preorder

Hi everyone, it’s time for another newsletter from us. Today we will cover: Online video demo of Mars The future of Mars More specifications of Jupiter and Saturn Our little lottery giveaway Order book opening
Online video demo of Mars We made a promise to you all not to take any payment of any device until we could show you a working prototype, well today it’s finally here. Our developers have been working almost round the clock to get this box hashing as fast as possible, we said Mars would hash at 6 GH/s and in the video you can see exactly how fast we managed to make it go. The Mars prototype is as the name suggests, a prototype. As you can see it doesn’t even have a case yet. The performance of our device is, and always will be, more important to us than the look. We know it won’t win any design awards but we are engineering for speed first and foremost. Please have a look at the video which can be found here. 100%
The Future of Mars Even with the new improvements of the Mars device it still has a few issues. It’s not anywhere near as efficient as Jupiter or Saturn in terms of $’s per Hash and it will really only mine Bitcoins. To sum up, we don’t think with the difficulty increasing at the current rate it’s good value for money and if it’s not good for you it’s not good for us. We will let our competitors sell devices with this kind of speed so we can concentrate on the ground breaking devices. We know a lot of people have ordered the device simply to gain a queue placement for Jupiter and quite a few people have asked us not to send them the device but to charge them and just allow them to use the queue placement. So given all of the above we have decided that we will remove Mars in its current form from sale. That leaves a few questions I’m sure. So let me try to alleviate your worries, anyone who has a registration for the Mars device will be able to use that queue placement for either a Jupiter or a Saturn, simply order one of those in the our shop with the same email address you registered your Mars device against and we will do the rest. Then there are the people who wanted the Mars device to mine other types of coins, what we will do is produce a new device based on the Mars type setup (with a case). It will be announced fully in the next few months but I can tell a few things today. We will target this new device against all the currencies we can. Not just litecoin, namecoin etc but also many others. The new FPGA based device will then have a much longer life expectancy and produce a much better ROI than Mars ever could. We will also be making updates available to the firmware if and when new types of coins come out. Removing Mars from sale will also free up some of our internal resources enabling them to work on Jupiter and Saturn and hopefully bring the delivery of those devices forward.
Order books now open for payment
The order books are now open for the first time allowing full ordering and payment of the Jupiter and Saturn devices. Everyone already has their place in the queue so we are giving everyone 7 days to pay and maintain that place. If there are any technical issues with our website or payment portals over the next 7 days we will of course increase this period accordingly. Once the 7 days are over we will provide everyone with their final shipping queue placement. We are able to ship hundreds of devices a week using the agreements we have in place with the factories so we still expect to be able to serve the vast majority of customers in September. Unlike others in this industry we will not be doing the assembly in house it will be done at the same professional assembly lines which ORSoC have been using for years. visit for more info
Our little lottery giveaway
for those of you who are able to pay in the first 48 hours starting from now. we will enter your email address into a lottery. After 48 hours we will randomly select three queue numbers, the first name chosen will get a free Jupiter and Saturn, the second will get a free Jupiter and the third will get a free Saturn. We will then contact you and ask if we can make your name and country/state public on our site. We will add the devices to your account and ship them free of charge to you along with your order.
We will also be offering tailored hosting of our own devices. Hosting packages offered will be specially made for each hosting customer. Please contact us at [email protected] for more information about hosting. Some benefits of hosting:
No costs for shipping/import taxes All costs included no hidden extra management fees Your hardware will be monitored 24/7 by our staff Your box will hash for you on day one 95% uptime guarantee For those of you interested in hosting please choose Stockholm pickup as the shipping method We will release final costs soon and if you want to use our hosting that’s fine, if you want to then have the box shipped you can simply pay for the shipping and we will ship your box instead. What’s next? What we will do over the next few weeks is provide more news on our Website/Facebook page and our Twitter feed. We will send out regular newsletters and keep the news section of our site up to date with all development.

[WTS] Altera DE2-115 FPGA board - capable of 100 MHash/s with incredibly low power!
Can count the number of times I've used this on one hand, never really bothered setting up a mining setup after my video card one - as I had planned to do with this board.
I can ship internationally for an extra 5 BTC.
Selling for a total of 30 BTC (shipping to Australia inclusive) or 35 BTC with shipping internationally inclusive. Worth $595 in non-crypto currency!
Open to negotiation!
