5 Best Bitcoin Mining Hardware ASIC Machines (2020 Rigs)
Bitcoin Mining Guide - Getting started with Bitcoin mining
Technical Questions: Mac Nodes & Servers
Hi guys, I posted this over at BitcoinBeginners but it hasn’t received a lot of useful input. I’ve read the FAQ there and searched around the web for answers, but could really use your help. I have a dedicated 2011 MacBook Pro running High Sierra that I’d like to use in support of Bitcoin. So far, I have installed and verified GPG Suite and Bitcoin Core following instructions from bitcoin.orf. It is now synced, and I hope to add block explorer, a lightning node, and an electrum server. Once complete, I’d like to create some tutorials and guides to help others who have old Macs, since there is already a lot of good info for Windows and Linux. I found this guide on Medium talking about Power Node Launcher, but it’s doesn’t have the same emphasis on security as the other tools I’ve setup. Before taking next steps, I’d like input from the community on the order of steps and trusted sources for installing the aforementioned programs. If there is anything else I can do with my computer and bandwidth to help Bitcoin, please let me know. Specifically, if I am able to setup a lightning node, would it help if I stored some bitcoin on it to support transactions? Should I setup a slow simple mining program or run an older ASIC miner that is not part of a pool just to help diversify the network? Should I setup a satellite connection as Andreas suggested in one of his older videos? Thanks for your input.
New England New England 6 States Songs: https://www.reddit.com/newengland/comments/er8wxd/new_england_6_states_songs/ NewEnglandcoin Symbol: NENG NewEnglandcoin is a clone of Bitcoin using scrypt as a proof-of-work algorithm with enhanced features to protect against 51% attack and decentralize on mining to allow diversified mining rigs across CPUs, GPUs, ASICs and Android phones. Mining Algorithm: Scrypt with RandomSpike. RandomSpike is 3rd generation of Dynamic Difficulty (DynDiff) algorithm on top of scrypt. 1 minute block targets base difficulty reset: every 1440 blocks subsidy halves in 2.1m blocks (~ 2 to 4 years) 84,000,000,000 total maximum NENG 20000 NENG per block Pre-mine: 1% - reserved for dev fund ICO: None RPCPort: 6376 Port: 6377 NewEnglandcoin has dogecoin like supply at 84 billion maximum NENG. This huge supply insures that NENG is suitable for retail transactions and daily use. The inflation schedule of NengEnglandcoin is actually identical to that of Litecoin. Bitcoin and Litecoin are already proven to be great long term store of value. The Litecoin-like NENG inflation schedule will make NewEnglandcoin ideal for long term investment appreciation as the supply is limited and capped at a fixed number Bitcoin Fork - Suitable for Home Hobbyists NewEnglandcoin core wallet continues to maintain version tag of "Satoshi v0.8.7.5" because NewEnglandcoin is very much an exact clone of bitcoin plus some mining feature changes with DynDiff algorithm. NewEnglandcoin is very suitable as lite version of bitcoin for educational purpose on desktop mining, full node running and bitcoin programming using bitcoin-json APIs. The NewEnglandcoin (NENG) mining algorithm original upgrade ideas were mainly designed for decentralization of mining rigs on scrypt, which is same algo as litecoin/dogecoin. The way it is going now is that NENG is very suitable for bitcoin/litecoin/dogecoin hobbyists who can not , will not spend huge money to run noisy ASIC/GPU mining equipments, but still want to mine NENG at home with quiet simple CPU/GPU or with a cheap ASIC like FutureBit Moonlander 2 USB or Apollo pod on solo mining setup to obtain very decent profitable results. NENG allows bitcoin litecoin hobbyists to experience full node running, solo mining, CPU/GPU/ASIC for a fun experience at home at cheap cost without breaking bank on equipment or electricity.

There is no boss on NewEnglandcoin. Nobody nor the dev owns NENG. We know a coin is worth nothing if there is no backing from community. Therefore, we as dev do not intend to make decision on this coin solely by ourselves. It is our expectation that NewEnglandcoin community will make majority of decisions on direction of this coin from now on. We as dev merely view our-self as coin creater and technical support of this coin while providing NENG a permanent home at ShorelineCrypto Exchange.

Welcome All to the GPUMining Crash Course! With the increase in prices in cryptocurrency, a lot of people are getting back into mining and a lot of people are brand new to the concept overall. So, I quickly wrote this crash course to help you understand what to expect and how to successfully mine your first cryptocurrency. This crash course isn't gonna have all of the fluff you'd see in a normal publication. This is just everything you need to know to get up and running on your first cryptocurrency mining rig.
What is cryptocurrency mining?
One of the main things about cryptocurrencies is that they are "decentralized". Sounds great, but WTF does that even mean? Well, the easiest way to explain it is... You know how if you want to send your friend/family money digitally, you can do so through your bank. Your bank likely takes a transaction fee and in a few days they will transfer the money. Since cryptocurrencies are decentralized, they don't have a bank or organization to fulfill the transfer of money. Instead, they outsource the computing power of their cryptocurrency network to miners (soon to be you). These miners are verifying transactions, securing the blockchain, and powering the cryptocurrency's specific network among other things. As an incentive, the miners collect transaction fees on the transactions that they verify and collect block rewards while new currency is still being introduced into the ecosystem.
What kind of rig should I build?
You can mine cryptocurrencies using your CPU, GPU, FPGA, or ASIC, but this is a GPU Mining subreddit, so I will cater this to GPUs. For building a great all-around GPU rig, there are two models of GPUs that I'd recommend:
Both of these GPUs have solid hashrates across most mining algorithms and for a decent price! You should be able to find both of these kinds of GPUs used for around $200-$250 each, which is a great price if you know what happened during the last mining craze! ($200 GPUs were out of stock everywhere and people were reselling them for $600+ each) There are also plenty of great AMD GPUs for mining, but I've worked mostly with Nvidia so that's why both of my recommendations are Nvidia and not AMD. Other parts to your rig that you'll need are listed below. Most of these can be pieces of crap and are just needed to make the rig actually run, but the one spot you DON'T want to cheap out on is the power supply unit. A decent power supply unit will keep your home from burning down while also keeping your rigs up and running smoothly. Here are my recommendations:
Motherboard - This Motherboard can hold up to 6 GPUs (considered a full rig) with the use of risers. It is decently priced and will fit nearly any mining rig upgrades that you make in the future.
CPU - You really just need the most basic CPU you can find, it's not very essential to mining unless you're CPU mining, but even then... CPU mining isn't very profitable for how expensive CPUs can be.
RAM - All you really need is about 4GB to keep this thing running. If you want more, go for it, but it's not neccessary in most cases.
Power Switch - Doesn't need to be fancy, just needs to turn the thing on and off
PowerSupply - Don't cheap out here! Pay for a quality PSU and save yourself the headache and be safe with a solid PSU. Get a GOLD quality PSU at a MINIMUM! Platinum is good too, but probably unnecessary. The linked 1300w PSU will support most 6 GPU rigs, if you're going for higher tier GPUs like a 1080ti and above or if you're having more than 6 GPUs on a single rig then you'll need something stronger.
GPU Risers - I use this kind. They work and they're not shitty. They do require 6pin for power. Use a Molex converter if needed, but going 6pin directly from your PSU is best. Your 8+6pin will probably be a little bit short, so you'll need some 6pin extenders. EVGA will sell them you for a few bucks each, but you have to call as they're not listed on the site. DON'T YOU DARE THINK OF USING A SATA CONNECTION UNLESS YOU WANT YOUR ENTIRE MINING OPERATION TO BURN DOWN AND TAKE EVERYTHING ELSE WITH IT! SATA IS NOT RATED FOR THE POWER THAT YOU NEED!!!!
Kilowatt Meter - So that you can monitor your power consumption from the wall (much more accurate than trying to calculate each piece of hardware individually). Also helps when overclocking for a higher efficiency.
120GB Solid State Drive - SSDs are pretty damn cheap now. Just get it instead of your prehistoric HDD. Also, make sure you get AT LEAST 120GB! Many of the popular cryptocurrencies like BEAM and GRIN will demand quite a bit of virtual memory, so you'll need the extra space on your SSD to compensate for that.
Something to put your rig on - This one seems to be popular, but pretty much anything will do. I literally used a shoe rack and zip ties. You just need something that will give the GPUs airflow to breathe and keep the rig organized as a whole.
Windows 10/Linux Operating System - Pretty self explanatory here. Don't go with any of the MAC OS or Apple Products. They're extremely over priced and nearly useless in the mining world.
She's built, now what?
Now you need to do a few things. I am a Windows miner, so I will be speaking to Windows here:
Update Windows - Do all of the updates. Just do it.
Update Drivers - Go to the EVGA website and download GeForce experience. It will keep your GPU drivers up to date.
Go to Windows Device Manager and make sure all of your GPUs show up under "Display Adapters". If it is there, but it isn't showing the Name/Model of the GPU as the name, right click it and select "Update Driver". This should fix it.
Assuming you've done all of this, you're ready to download a mining application.
There are tons to choose from! Claymore, Phoenix, EWBF, LolMiner, etc... It can be overwhelming pretty quickly since they all have different algorithm support, speeds, efficiencies, and a whole lot more. On top of that, in order to get them running you need to set up batch files to call the proper exe, point you to the correct pool, and a whole bunch of other stuff that can be confusing to a new user. Not to mention, you will probably need a separate miner, config file, batch file, etc. for each different algorithm that you're interested in mining on. Instead, I recommend that you download a miner management software that will take care of most of this tedious work for you. There are a few in the sidebar, but the /GPUMining favorite is AIOMiner. It was developed by our very own community member, xixspiderxix with the intention of making mining as easy as possible to do and without any fees. It supports over 100 different algorithms, so you'll be able to mine nearly ANY cryptocurrency you'd like. Just download it from their website and it will take you through a quick tutorial to help you get set up! You can also connect your rig to their website for remote monitoring and control. You've probably seen a few of their posts around this subreddit. Other Windows mining softwares include:
many more you can find from google searching
Note: Many mining softwares have fees built into them. Most are around 1%, but can go as high as 5% or greater! You want a mining software with little or no fees at all so that you get to keep as much cryptocurrency as possible. These fees aren't something you actively pay, the software will automatically take it by mining on the developers behalf for a given amount of time and then switching back to mining on your own behalf. So, please be diligent in the software that you evaluate and make sure it is reputable.
I keep hearing about NiceHash. What is that?
The asshole of the mining industry. Jk, but not really. NiceHash is a software program that allows you to sell your rig's hashing power to someone on their marketplace. They market themselves as profitable mining, but you're not really mining. You're selling your power in exchange for Bitcoin. They did a great job telling people that with them, you're always mining the most profitable coin, but that's just not true. Since it is a mining marketplace, they make you mine whatever their most expensive contract is. If their contracts are below market prices, then you're not operating as efficiently and profitably as you could be. NiceHash also has a sketchy history, which continues to this day. In 2017, they were hacked and lost $65M worth of Bitcoin. No one got paid out for MONTHS and many of their executives conveniently resigned. Their platform is also used to destroy cryptocurrencies. Since people are able to purchase mining power on their platform, people have used their platform to purchase enough mining power to control individual cryptocurrencies and duplicate coins, which increased the malicious user's wealth while completely destroying the integrity of the coin's blockchain. HoriZEN (formerly ZenCash), Ethereum Classic, and many other great cryptocurrencies have been the victim of NiceHash's platform. For this and many other reasons, we highly recommend that you stay AWAY from Nicehash. We understand that it is extremely easy to use and you get paid in bitcoin, but they are destroying the industry with their greed and lack of motivation to change their platform for the protection of cryptocurrencies.
This is pretty much everything you need to know to get started. We covered the hardware, setting up the software, which software to use, and AIOMiner's tutorial will get you up to speed on how to actually mine the cryptocurrency that you want better than I can explain it, so I'll leave that part to them. If you have any questions on this crash course, please leave a comment below where myself and other community members will be able to help you out.
What is Garlicoin? Garlicoin is a community-based cryptocurrency that was originally founded based on a meme of garlic bread that reached the front page of Reddit. The concept of a memecoin is similar to that of the more well-known Dogecoin, but Garlicoin is actually a fork of Litecoin, which is itself a fork of Bitcoin. What technology is behind Garlicoin? As it's just a fork of Litecoin, it's basically the same thing with how the addresses, wallets, etc. work but there are a few key differences. Most importantly, the mining algorithm is called "Allium," which was specially developed to be ASIC-resistant. Originally the coin was based on Scrypt-N but a hard-fork occurred on 2/16/2018 in order to solve the problem of ASICs that were discovered on the network. Another key difference is that Garlicoin only has a 40 second block time, so transactions confirm very fast. Who developed Garlicoin? Disclaimer: Most of the code was copy-pasted. However, there are a few developers that continue to work on the project. u/DigitalizedOrange was the founder, he likes anime. Most of the moderators are also part of the team. Should I invest in Garlicoin? Like any cryptocurrency, don't treat it as investing. Treat it like speculation or gambling. If you're not willing to lose that money, the answer is no. Garlicoin has even more risk behind it as it isn't trying to be at the forefront of technology or anything. All we have is meme appeal and garlic bread. Why did the price just moon? Or why did it just crash? With such a low volume in Garlicoin exchanges, the price can be easily manipulated. Trade with caution. How can I start mining? Check out the mining section in the links and tutorials down below. There's a great guide to setting everything up by Pandawan. Why does the explorer show a different value than my web-based wallet? Some web-based wallets, such as GarlicWallet.com, are shared wallets meaning that you don't own the private keys and the website will move your coins around between addresses. The address you receive just credits your online account so you can withdraw a specific amount however you technically do not own those coins and if the site goes down then you may lose access to them forever. For that reason, it's highly recommended that you use a wallet where you own the private keys. Paper wallets are the most secure for large values as long as you physically keep them in a safe place, as they cannot be hacked. What other Garlic Bread goodness can I get into? Check out GBDS (dating simulator) and GarlicBreadMemes if you can't get enough. I have another question that isn't answered here! First try using the search bar for this subreddit. If you can't find an answer then you can create a new thread and someone from the community will most likely help you. If I forgot to add a commonly asked question to this guide, or if there's anything else you'd like to see explained/linked here, please let me know in the comments.
New people please read this. [upvote for visibility please]
I am seeing too many new people come and and getting confused. Litecoin wiki isn't the greatest when it comes to summing up things so I will try to do things as best as I can. I will attempt to explain from what I have learned and answer some questions. Hopefully people smarter than me will also chime in. I will keep this post updated as much as I can. Preface Litecoin is a type to electronic currency. It is just like Bitcoin but it there are differences. Difference explained here. If you are starting to mine now chances are that you have missed the Bitcoin mining train. If you really want your time and processing power to not go to waste you should mine LTC because the access to BTC from there is much easier. Mining. What is it? Let's get this straight. When making any financial commitment to this be prepared to do it with "throw away" money. Mining is all about the hashrate and is measured in KH/s (KiloHash/sec). Unlike the powerful ASICs (Application Specific Integrated Circuit) that are used to mine bitcoins using hashrates in the GH/s and even TH/s, litecoin mining has only been able to achieve at the very best MH/s. I think the highest I've seen is 130 MH/s so far. Which leads us to our next section. Mining Hardware While CPU mining is still a thing it is not as powerful as GPU mining. Your laptop might be able to get 1 a month. However, I encourage you to consult this list first. List of hardware comparison You will find the highest of processors can maybe pull 100 KH/s and if we put this into a litecoin mining calculator it doesn't give us much. Another reason why you don't want to mine with your CPU is pretty simple. You are going to destroy it. So this leaves us with GPUs. Over the past few months (and years) the HD 7950 has been the favourite because it drains less power and has a pretty good hashrate. But recently the introduction of the R9 290 (not the x) has changed the game a bit. People are getting 850 KH/s - 900 KH/s with that card. It's crazy. Should I mine? Honestly given the current difficulty you can make a solid rig for about $1100 with a hashrate of 1700 KH/s which would give you your investment back in about a month and a half. I am sure people out there can create something for much cheaper. Here is a good example of a setup as suggested by dystopiats PCPartPicker part list / Price breakdown by merchant / Benchmarks
Prices include shipping, taxes, and discounts when available.

Estimated Hashrate (with GPU overclocking) : 1900 KH/s Hardware Fundamentals CPU - Do you need a powerful CPU? No but make sure it is a decent one. AMD CPUs are cheap to buy right now with tons of power. Feel free to use a Sempron or Celeron depending on what Motherboard you go with. RAM - Try to get at least 4 GB so as to not run into any trouble. Memory is cheap these days. I am saying 4 GB only because of Windoze. If you are plan to run this on Linux you can even get away with less memory. HDD Any good ol 7200 RPM hard drive will do. Make sure it is appropriate. No point in buying a 1TB hard drive. Since, this is a newbie's guide I assumed most won't know how to run linux, but incase you do you can get a USB flash drive and run linux from it thus removing the need for hard drive all toghether. (thanks dystopiats) GPU - Consult the list of hardware of hardware I posted above. Make sure you consider the KH/s/W ratio. To me the 290 is the best option but you can skimp down to 7950 if you like. PSU - THIS IS BLOODY IMPORTANT. Most modern GPUs are power hungry so please make sure you are well within the limits of your power consumption. MOTHERBOARD - Ok, so a pretty popular board right now is Gigabyte GA-990FXA-UD3 and the ASRock 970 Extreme4. Some people are even going for Gigabyte GA-990FXA-UD5 and even the mighty Gigabyte GA-990FXA-UD7 because it has more PCI-E slots. 6 to be exact. However you may not need that much. With risers you can get more shoved into less. PCI-E RISERS - These are called risers. They come in x16 to x16 and x1 to x16 connections. Here is the general rule of thumb. This is very important. Always get a POWERED riser otherwise you will burn a hole in your MoBo. A powered rise as a molex connector so that additional power from PSU can be supplied. When it comes to hardware I've provided the most basic knowledge you need. Also, take a look at cryptobader's website. This is very helpful. Please visit the mining section of Litecoin Forums and the litecoinmining subreddit for more indepth info. Mining Software Now that you have assembled your hardware now you need to get into a pool. But before you do that you need a mining software. There are many different ones but the one that is most popular is cgminer. Download it and make sure you read the README. It is a very robust piece of software. Please read this if you want to know more. (thanks BalzOnYer4Head) Mining Pools Now that your hardware and software is ready. I know nothing about solo mining other than the fact that you have to be very lucky and respectable amount of hashing power to decrypt a block. So it is better to join pools. I have been pool hopping for a bit and really liked give-me-coin previously known to the community as give-me-ltc. They have a nice mobile app and 0% pool fees. This is really a personal preference. Take a look at this list and try some yourself. How do I connect to a pool? Most pools will give you a tutorial on how to but the basics are as follows:
Signup for a pool
Create a worker for your account. Usually one worker per rig (Yes people have multiple rigs) is generally a good idea.
Create a .run file. Open up notepad and type cgminer.exe -o (address_to_the_miningpool:port_number) -u (yourusername.workername) -p (your_worker_password_if_you_made_one). Then File>Save As>runcgminer.run (Make sure the drop down is set to "All Files" and .txt document.) and save in the same folder as cgminer. That's it.
Double click on runcgminer.run (or whatever you named it) and have fun mining.
Mining Profitability This game is not easy. If it was, practically everyone would be doing it. This is strictly a numbers game and there are calculations available that can help you determine your risk on your investments. 4 variables you need to consider when you are starting to mine: Hardware cost: The cost of your physical hardware to run this whole operation. Power: Measured in $/KwH is also known as the operating cost. Difficulty rate: To put it in layman's terms the increase in difficulty is inversely proportional to amount of coin you can mine. The harder the difficulty the harder it is to mine coin. Right now difficulty is rising at about 18% per 3 days. This can and will change since all you miners are soon going to jump on the band wagon. Your sanity: I am not going to tell you to keep calm and chive on because quiet frankly that is stupid. What I will tell you not to get too carried away. You will pull you hair out. Seriously. Next thing you will need is a simple tool. A mining profitability calculator. I have two favourite ones. coinwarz I like this one cause it is simple. The fields are self explanatory. Try it. bitcoinwisdom I like this one because it is a more real life scenario calculator and more complicated one (not really). It also takes increasing difficulty into account. Please note: This is the absolute basic info you need. If you have more questions feel free to ask and or google it! More Below.
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: https://github.com/ethereum/wiki/wiki/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: https://en.bitcoin.it/wiki/Block_hashing_algorithm 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: https://medium.com/quarkchain-official/order-statistics-based-hash-algorithm-e40f108563c4 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: https://github.com/QuarkChain/pyquarkchain/wiki/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.
