How To Mine Ethereum And Use Pool? - Ethereumpool.co: Ethereum Mining Pool

That's it, you have installed c++ version of ethereum and ethminer included You dont neet to set up account on local, you can mine directly to exchange ethminer -G -F ethminer -G -F IN MHASH]@[ADDRESS]@[OPTIONAL RIG NAME] -G means mining on GPU, if you want try cpu, just do NOT put G Minimal hashrate = 0.01 MHash Please set valid hashrate in mining url, if you set higher, you may not earn anything, if you set too low, pool will adjust diff to avoid share flood(but you may get more stale shares, so keep values real) If you have multiple rigs connected here with the same declared hashrate, for example you have 2rigs x 60mhash, dont put [email protected] please use [email protected] and [email protected] since this parm is not only hashrate but also unique id for each mining address! You should get valid share average one per 2-3mins How does pool calculate revenue for each miner? PPLNS/Time Prop - If time between last mined and previous mined block is longer than 8 minutes then pool will split proportionally between all miners which submitted valid shares depending on their diff. But if time between mined blocks is smaller than 8 minutes, then we will take previous shares from last 8 minutes and split according to diff and number of shares submitted When your balance exceed 0.1 ether. Withdraws are processed once a day. Yes, we are verifying every miner step, we have implemented complex proof of work validation Run ethminer -G -M and result of test divide by 1000000 Contact us if you exprience any bug, or have any doubts or just cant set up your miner. Click support in right top corner! What if i want to mine directly to my local account ? We recommend to you install geth since it's more clear Continue reading >>

Ethereum Mining Guide For All Operating Systems

BestVPN Guides Ethereum Mining Guide for all Operating Systems Ethereum Mining Guide for all Operating Systems Ethereum mining can be difficult, I know! In this guide, Ive covered everything from the bottom up so whether youre a beginner or a pro you should be able to glean some useful insight and learn something new. It doesnt matter if youre planning to do mining using Linux, ethOS or Windows. Ive made sure to cover the steps for each. You will also find some great tips, tricks, optimizations, and solutions to common troubleshooting issues. If you dont have time to read all of it today, then bookmark this page, or sign up to our email list and receive it as a free ebook! Ethereum is an open blockchain platform similar to Bitcoin but with additional in-built flexibilities. With Ethereum, the blockchain can be considered to be intelligent thanks to the Ethereum Virtual Machine and Smart Contracts. Whereas with Bitcoin its a glorified ledger. With Ethereum you can execute code on the blockchain in a distributed way. These are called Smart Contracts. These allow you to set up a system, whereby a person will only receive payment under certain conditions. As Ethereum grows, the scale and complexities of these contracts are expected to increase. Smart Contracts is what has given Ethereum such a solid footing, as like with the blockchain has a functional use. If youre interested in about how Ethereum came about and wanted to find out more about it, then watch this YouTube video by COO, Stephan Tual . Before you determine if you should go on your Ethereum mining adventure; youll need to decide whether its going to be profitable or not. While, on the surface, this is incredibly easy, as Ill show below, you must be aware that mining is very much like trading. Cryptocurrency pri Continue reading >>

Heres How I Built A Private Blockchain Network, And You Cantoo

Heres how I built a private blockchain network, and you cantoo Nothing helps understand blockchains better than building oneyourself This is PART-4 of The Product Managers guide to the Blockchain series! If you somehow landed on my publication for the first time, Welcome! I recommend you start from part 1 , and then read part 2 and part3 before reading this post. However If you are the explorer type, read on! (Update: Heres the latest part 5 of the blockchain series ) In Part 3 of this series, we looked at the mechanics of Ethereum and also talked about the concept of Ethereum Accounts, Smart Contracts and Gas the fuel that helps all these pieces to work together. Its been a lot of reading so far, but while you can read all the blockchain content available on the internet, nothing helps understand blockchains better than building one yourself. So thats what I did. You can simply follow this post and build a little prototype to see how everything weve talked about so far comes together. Here is what we will accomplish in this post, Weve seen this before , but basically the Ethereum blockchain network is simply lots of EVM (Ethereum Virtual Machines) or nodes connected to every other node to create a mesh. Each node runs a copy of the entire blockchain and competes to mine the next block or validate a transaction. Whenever a new block is added, the blockchain updates and is propagated to the entire network, such that each node is in sync. To become a node in the Ethereum network, your computer will have to download and update a copy of the entire Ethereum blockchain. To achieve this Ethereum provides tools that you can download, connect to the Ethereum network with and then interact with it. These are: Geth if you have experience with web development and are interested i Continue reading >>

How To Build A Private Ethereum Blockchain

How To Build A Private Ethereum Blockchain

Step 5: Create an account to use as the coinbase for your blockchain node An Ethereum account is the public key that stores ether that will be used in your private blockchain to pay for gas fees. Before we start the blockchain, we need to create an account that the mining rewards will be deposited too. You will be prompted to set a password for the account, DONT FORGET YOUR PASSWORD, you will not be able to recover it later and wont be able to spend the ether you mine or unlock that account. After entering the password twice, you should expect to get a response back like this: Address: {941f1f0b08757457be0b52d83a1e3e566473ed61} This is the public key of the Ethereum account. Ethereum convention is to prefix accounts with 0x so the account is sometimes seen as 0x941f1fobo8757457be0b52d83a1e3e566473ed61. Step 6: Create JSON File for Genesis Block to Bootstrap Private Blockchain Using a text editor, create a file CustomGenesis.json with the following contents: Step 7: Initialize the blockchain from your CustomGenesis.json file go-ethereum/build/bin/geth init ./CustomGenesis.json You should expect to see output similar to this: INFO[0223|20:20:03] Allotted 128MB cache and 1024 file handles to /home/ubuntu/.ethereum/geth/chaindata INFO[0223|20:20:04] closed db:/home/ubuntu/.ethereum/geth/chaindata INFO[0223|20:20:04] Allotted 128MB cache and 1024 file handles to /home/ubuntu/.ethereum/geth/chaindata INFO[0223|20:20:04] successfully wrote genesis block and/or chain rule set: 5dd3be94dcbf5216aaa3e82700fb51a831257df5d45d984941a0a32ee0f960d8 Congratulations! You have initialized a private Ethereum blockchain!! Before we move on, lets take a break for some optional exploration of the files we have generated. In your home directory you will now see a hidden directory called.ether Continue reading >>

Choosing An Ethereum Client | Truffle Suite

Choosing An Ethereum Client | Truffle Suite

There are many Ethereum clients to choose from. We recommend different clients depending on whether you are developing or deploying. We recommend Ganache , a personal blockchain for Ethereum development that runs on your desktop. Part of the Truffle Suite, Ganache simplifies dapp development by placing your contracts and transactions front and center. Using Ganache you can quickly see how your application affects the blockchain, and introspect details like your accounts, balances, contract creations and gas costs. You can also fine tune Ganache's advanced mining controls to better suit your needs. Ganache is available for Windows, Mac and Linux, and you can download it here . Ganache, when launched runs on It will display the first 10 accounts and the mnemonic used to create those accounts. ( Read more about account mnemonics .) By default, Ganache will use the following mnemonic: candy maple cake sugar pudding cream honey rich smooth crumble sweet treat This mnemonic can be changed to be randomly generated, or you can input your own. Warning: Do not use this mnemonic on the main Ethereum network (mainnet). If you send ether to any account generated from this mnemonic, you will lose it all! We also recommend using Truffle Develop, a development blockchain built directly into Truffle. Truffle Develop helps you set up an integrated blockchain environment with a single command, no installation required. Run Truffle Develop by typing the following into a terminal: This will run the client on It will display the first 10 accounts and the mnemonic used to create those accounts. ( Read more about account mnemonics .) Truffle Develop uses the same mnemonic every time to make developing your applications as easy as possible: candy maple cake sugar pudding cream honey rich smoot Continue reading >>

Ethereum Mining 101: Your Complete Guide

Ethereum Mining 101: Your Complete Guide

The world has gone digital, from the development of smart homes to the development of innovations that promote seamless transactions. Every industry is feeling the impact of technology now more than ever. In every part of the world, the technologically driven goals remain the same: the maximization of profit and the promotion of sustainable development in all spheres of life. It is this yearning to make life as easy as possible that brought about the birth of cryptocurrency . Ethereum seeks to make these aspirations come true. The platform boasts of several applications that help users carry out everyday tasks in a simple fashion. What is Mining, Ethereum Mining and Where Does Ether Come From? Mining is a computationally intensive work that requires a lot of processing power and time. Mining is the act of participating in a given peer distributed cryptocurrency network in consensus. The miner is subsequently rewarded for providing solutions to challenging math problems. It is done by putting the computer's hardware to use with mining applications. All the information on cryptocurrency transactions must be embedded in data blocks. Each block is linked internally to several other blocks. This creates the blockchain . These blocks must be analyzed as fast as possible to ensure a smooth running of transactions on the platform. However, the issuers of such currencies do not have the processing capabilities to handle this alone. It is where miners come in. A miner is an investor that devotes time, computer space and energy to sorting through blocks. When the mining process hits the right harsh, they will submit their solutions to the issuer. After verification, the issuer of the currency offers rewards which are portions of the transactions they helped in verifying. They als Continue reading >>

Ether Mining First Attempt

Ether Mining First Attempt

Run geth in the screen session, which begins to download the blockchain: You can now detach from the screen session by hitting ctrl a and d and disconnect from the machine. Periodically check back on the progress of geth downloading the blockchain. Reattach to the screen session and check the process: You will see an output that looks like the output below. When geth has caught up with the block chain, you will see messages with 1 block per line. Now we will mine Ether using the default ethminer. This is not recommended according to etherminer.org , but we will see how bad it is. sudo apt-get updatesudo apt-get install cpp-ethereum sudo apt-get updatesudo apt-get install cpp-ethereum Benchmark the miner to measure its hash rate. You will need to run it twice. The first time it runs it builds a DAG. The second time it runs it will run the actual benchmark: I got about 19 MH/s (i.e. 19 million hashes per second) on the p2.xlarge instance. Create a new screen window by hitting ctrl-a and c. Now, mine some Ether in the new window. Use the -F option to send it to your account via ethermine.org: ethminer -F -G ethminer -F -G The long string that begins with 0x7B and ends right before . is my Ether wallet. You should obviously use your own. Now, you can detach from the screen session with ctrl-a and d and check back once in a while to see if it is still running. Also check if Ether accumulates in your wallet. Finally, you can check the dash board (mine) to see the progress. Now, lets tally the Ether that was generated and subtract the cost for the AWS instance. The AWS spot price for one p2.xlarge is about $0.2/hour. According to ethermine, my rig generates about $0.01 worth of Ether per hour. That gives a negative result of $0.01 $0.2 = -$0.19/hour. The AWS p2.xlarge instanc Continue reading >>

How To Connect To An Ethereum Mining Pool?

How To Connect To An Ethereum Mining Pool?

How to connect to an Ethereum mining pool? Ethereum mining is best done by joining a mining pool so that there is a steady stream of Ether's into your wallet and in this guide we will show you a step by step process to do just this. In our "How to Mine Ethereum on a Windows PC" we showed you how to install all the software to get your computer mining with its graphics card and failing that, with its CPU. However this isn't the whole process, as when you mine on your own the chance of finding a block is incredibly small considering the total amount of hashing power in the network - so the best option is to join a mining pool to smooth the volatility of returns - you can read about the benefits of joining a bitcoin or ethereum mining pool here . Step 1: If you have gone through our guide here on how to set up your computer to mine ethereum you are most of the way there - in fact all you need is an address which you can get from the EthDev wallet - which is basically a nice interface to doing exactly the same process. The reason you need a wallet or address is to tell the pool where to pay your money! You don't need to sync the blockchain - the mining pool provider will do this for you! Step 2: Once you have an address you need to start ethminer - and if you haven't installed this you can do so by following the section. 2.1Now you need to download Ethminer which makes your GPU or CPU run the hashing algorithm that is integral to securing the Ethereum network through proof of work. You can download this here and be sure to scroll down to the bottom of the page to get the right version - the latest and most up to date one is right at the end. 2.2 Click on the download and click install. Your firewall can cause issues but just click allow if it does so - the same is true of Continue reading >>

Getting Started With Ethereum Using Cpp-ethereum

Getting Started With Ethereum Using Cpp-ethereum

Getting Started with Ethereum Using cpp-ethereum Our previous guides regarding mining and using Ethereums Ether (ETH) coins were based on the Go Ethereum implementation ( source ) as we find it easier to be used than the C++ implementation of the Ethereum client ( source ) even though we are actually using ethminer for the actual mining which is a part of cpp-ethereum and not go-ethereum package. The Go Ethereum implementation (geth) only comes with built in support for CPU mining, while the C++ implementation (eth) contains support for OpenCL GPU mining both as a part of the client as well as a separate miner (ethminer) and there is also a fork of ethminer with CUDA support available ( source ). So now it is time to get started with using the cpp-ethereum (eth) client for creatng a local wallet and for mining both solo on a local system or on an Ethereum mining pool using eth and ethminer. Our guide is for using eth and ethminer on Windows with binaries provided only for that OS (version 0.9.40 64-bit), though the usage should be the same or very similar on other operating systems, but you will need to compile or get binaries for the respective OS. We have tried to make the guide easy and simple to follow, so that you can begin using Ethereum and mining Ether in just a couple of minutes. First we need to create a local wallet and this is the first thing you will do when you run the eth client software. But before that a word of warning, if you have a working geth installation you should know that both Ethereum clients will use the same folder for the blockchain data by default, though the contents of the folder will not be compatible. The key files that are needed for you Ethereum wallet however will be stored in different places and each client will use ts own wallet Continue reading >>

Mining Ethereum On Windows Tim Coulter Medium

Mining Ethereum On Windows Tim Coulter Medium

Everyday I'm travelin'. Do do do do doo do do. This is going to be a quick guide. Ive got things to do, people to see, food to digest. You get the point. Still, mining on Windows involved enough technical steps and a few random guesses along the way that its likely Ive forgotten something. Comment, and Ill attempt to fill in the spots I missed. Before I get started, most of what Ive learned comes from Geniols post on the GPU mining forum . Alot can be found there. If you have questions, its worth a read. In order to mine correctly, were going to need to run two programs. The first is ethminer, which talks to your GPUs and does all the hashing work. The second is geth, which talks to the network and keeps up-to-date with the blockchain. Ethminer is written in C++ and comes from the project cpp-ethereum , whereas geth is written in Go and comes from the project go-ethereum . Well talk about installing both, and then follow up with how youll run each together. Ethminer comes with a few mostly simple steps, but you are building from source. If you havent built anything from source before this could be daunting. Ill try to make it as easy as possible, but again, Ive got things to do and all that jazz. This should download a bunch of stuff. You just gotta wait for it to finish. Next, cd back into /cpp-ethereum, and run: cmake -DETHASHCL=1 -G Visual Studio 12 2013 Win64 This will prepare the project for compiling. Great, youre most of the way there. Next, open up Visual Studio, and then find the ethereum.sln solution file within the /cpp-ethereum directory. Open that up. Visual Studio might complain about some things being the wrong format if it does, say okay and just let it do its thing. After it opens, its gonna scan some files and do some projecty-type organizational thin Continue reading >>

Ethereum Client Platforms: Parity Versus Go-ethereum

Ethereum Client Platforms: Parity Versus Go-ethereum

Ethereum Client Platforms: Parity versus Go-Ethereum Senior Associate, Total Portfolio Management at CPP Investment Board The next step in the Ethereum world, after mastering the basics of the Solidity language and the smart contract development, is about developing simple production applications. The key ingredient here is client software. In this article, I reviewparity, the newer client software layer, and compare it togeth,the product of the Homestead project. What does the client software do? It downloads the whole blockchain onto your system on a regular basis, keeping the tab on the whole network. It verifies all transactions and contracts on the blockchain. If you are building your own contracts, it broadcasts them to the network so that they are included in the next block and confirmed by the miners. Client software can also do the mining but these days you may need a super-computer do make any ether this way. Why is this important? In order to successfully integrate blockchain transactions into a real-world application, a reliable client layer is needed. Just using or another chain scanner for the back-end would be to defeat the purpose of blockchain, a verified decentralized transaction ledger. Differently coded, independently running clients only can provide the robustness, or "antifragility" (@nntaleb) of the blockchain. With both clients, I recommend downloading the source and compiling the code. The code changes so often than any binaries are already old when you get to them. The situation is complicated by multiple spam attacks on the Ethereum blockchain, including "from Shanghai with love" and , . There is no such thing as stable geth or parity clients so the latest commit is the best call. Both geth and parity require 2-4GB of RAM and 50-100GB of hard Continue reading >>

The Ethereum Foundations mission is to promote and support research, development and education to bring decentralized protocols and tools to the world that empower developers to produce next generation decentralized applications (dapps), and together build a more globally accessible, more free and more trustworthy Internet. I amproposing to the contributors that the C++ Ethereum client runtime ( cpp-ethereum ) be re-licensed from thecopyleft GPLv3 license to the more permissive Apache 2.0 license,to enable Ethereum software to be used as broadly as possible ( a long-standing plan ). This proposal only addresses the C++ clientruntimeand doesnot include Solidity or Mix (the C++ tools). There is another blog post detailing the likely operational steps in that process. This document seeks to explain why I am making that proposal. When we think aboutEthereum, we usually think about public chain, and more specifically we think about the public chain (the mainnet). That is quite natural within the frame of reference of Ethereum purely as a cryptocurrency, butit is a limited view of the possibilities which this new decentralized computing platform offers. Ethereum is much more than a better cryptocurrency. Ether is the fuel for the engine, but it is the Ethereum engineitself which opens up these new possibilities. The fuel is just a means to an end. We have the opportunity to build a set of technologies in the next few years which could havesimilar societal impact as when the Internet, the World Wide Web and open source languages, databases, etc. became available. We are building a decentralized computing platform which every individualon Earth should benefit from. These technologies need to reach into every nook and cranny of our computing fabric: big and small, public and pr Continue reading >>

To restore an account on a different node than it was created upon, first install the Mist browser (and then locate the keystore folder. In a machine with Mist installed, this folder is usually located in the following directories: Mac: ~/Library/Ethereum/keystore Linux: ~/.ethereum/keystore Windows: %APPDATA%/Ethereum/keystore Restoring an Ethereum account in Mist simply involves copying a text file containing a private key inside the keystore folder, and restarting Mist. If you have the entire keyfile as it was created in Mist, with a filename that begins with a UTC timestamp, you can drop that into the keystore folder and restart Mist. Your balances should load as soon as Mist is finished updating, sometimes sooner. If you only have your private key, simply drop it into a plaintext file, name it whatever you like, and place that in the keystore folder. Continue reading >>

Gpu Mining | Ethereum Frontier Guide

The algorithm is memory hard and in order to fit the DAG into memory, it needs 1-2GB of RAM on each GPU. If you get Error GPU mining. GPU memory fragmentation? you havent got enough memory. The GPU miner is implemented in OpenCL, so AMD GPUs will be 'faster' than same-category NVIDIA GPUs. ASICs and FPGAs are relatively inefficient and therefore discouraged. To get openCL for your chipset and platform, try: download: ADL_SDK8.zip and AMD-APP-SDK-v2.9-1.599.381-GA-linux64.sh ./AMD-APP-SDK-v2.9-1.599.381-GA-linux64.shln -s /opt/AMDAPPSDK-2.9-1 /opt/AMDAPPln -s /opt/AMDAPP/include/CL /usr/includeln -s /opt/AMDAPP/lib/x86_64/* /usr/lib/ldconfigreboot apt-get install fglrx-updates// wget, tar, openclsudo aticonfig --adapter=all --initialsudo aticonfig --list-adapters* 0. 01:00.0 AMD Radeon R9 200 Series* - Default adapter The following instructions are, for the most part, relevant to any system with Ubuntu 14.04 and a Nvidia GPU.

Is There A Difference Between Geth And The Cpp-ethereum Cli?

Is There A Difference Between Geth And The Cpp-ethereum Cli?

Is there a difference between geth and the cpp-ethereum CLI? I am a cpp dev and i want to have a look at the ethereum code so i chose the cpp-ethereum repo. Do geth and cpp-ethereum have the same CLI commands? I wasn`t able to find a list of the commands for cpp-ethereum (I can look at the argv loop but I also need the command list for quick reference). One difference I have already noticed is that you have different commands for the JSON RPC, i.e. geth --rpc vs eth -j. Is there a reason the CLIs are not uniform across clients? And are there differences between the other clients as well, e.g. parity, python ethereum? rosul Oct 30 '17 at 15:17 I have extensively used Geth and Geth-CLI. As far as I know, the only way we can interact with ethereum-cpp is using one of the methods mentioned in the documentation . I didn't even expect geth and ethereum-cpp to have same/similar commands. Geth has a CLI based off the golang debugger. Although, all types of ethereum node can be interacted using the web3 libraries . Continue reading >>
