Then why would it know to use your files... @lambocrypt you should do eth --help first and read params if i just run eth then also it says command not found Likely you haven't added the exec flag for it in linux Yeah, so just replace eth with ./eth in the tutorial and it would work but I would just use ganache for testing a dApp i wants to use cpp_ethereum to create a cluster private net, but after addPeer, use admin.peers can find another,but admin.nodeInfo not found geth is easy to create a test cluster,but how cpp_eth to create a local cluster test net someone else had use cpp_ethereum to create a local cluster test successful? @wangmaodong one website says geth is slow but ethereumjs-testrpc is lightweight and fast so m using that now i used to ethconsole to add peer,but happens "DISABLE: Disabling capability ' eth '. Reason: Peer from another fork." Hi guys. Sorry to bother you. Is there some documentation about how to deploy a smart contract on ethereum-cpp , please - providing this is possible ? i updated ethconsole to use web3.js 1.0 and it works with sync calls, using repl-promise. So its latest web3 but still can be called like in the past. can you please test if your cppTestExample.js still works? I made some changes and am not sure if these tests still run, clone the repo an call node ./ cppTestExample.js Continue reading >>

How Can I Install Ethminer On Ubuntu 17.04

How Can I Install Ethminer On Ubuntu 17.04

I was following this guide. sudo apt-get install software-properties-commonsudo add-apt-repository ppa:ethereum/ethereumsudo apt-get updatesudo apt-get install ethereum ethminergeth account new# copy long character sequence within {}, that is your # if you lose the passphrase, you lose your coins!sudo apt-get install linux-headers-amd64 build-essentialchmod +x NVIDIA-Linux-x86_64-367.35.runsudo NVIDIA-Linux-x86_64-367.35.runethminer -G -F --farm-recheck 200 On the command sudo apt-get install ethereum ethminer it fails with the error: Reading package lists... DoneBuilding dependency tree Reading state information... DoneE: Unable to locate package ethminer I did follow the instruction of adding the ethereum ppa so I am not sure why it will cannot find the ethminer package. Is the guide just out of date? I think the ppa will only work properly on 16.04. Might have to build it from source. Its called cpp-ethereum. ethdocs.org/en/latest/ethereum-clients/cpp-ethereum/ bob Jun 2 at 6:17 No wonder knowing that you can't install ethminer directly from apt install command, when I try to find ethminer package on Etherum's launchpad page , return with no avail. So basically the ethminer package doesn't belong to the ppa, it's unknown either the instruction article is outdated or other reason. I suggest you to read this , there are tutorials available on how to install ethminer from source depending on OS, though I haven't tested this method. I got this to work in 17.04 by downloading the ethminer binary directly from I also had to install the nvidia cuda drivers with this command sudo apt-get install nvidia-cuda-dev nvidia-cuda-toolkit nvidia-nsight I currently understand you should use the following: sudo apt-get install software-properties-commonsudo add-a 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 >>

Install The Command Line Tools

Install The Command Line Tools

Command line tools for the Ethereum Network These are tools for blockchain developers. The command line tools will allow you to connect your server to or run your application on the Ethereum blockchain or your own private blockchain. For security purposes , three independent implementations were created for Ethereum. The clients have almost identical functionality, so the one you pick is left to personal choice on platform, language and what your planned use is for the network. If you are building a business that needs to have maximum uptime guarantees to the Ethereum network, we recommend that you run at least one instance of both clients to ensure reliability. The Go implementation is called Geth. Geth has been audited for security and will be the future basis for the enduser-facing Mist Browser, so if you have experience with web development and are interested in building frontends for dapps, you should experiment with Geth. Install Homebrew and make sure it's up to date: Then use these commands to install ethereum: brew tap ethereum/ethereumbrew install ethereum For more, see the full documentation on Mac OSX Geth Download the latest stable binary , extract it, download the zip file, extract geth.exe from zip, open a command terminal and type: chdir open geth.exe For more, see the full documentation on Windows Geth sudo apt-get install software-properties-commonsudo add-apt-repository -y ppa:ethereum/ethereumsudo apt-get updatesudo apt-get install ethereum For other environments and more instruction, see the full documentation on Geth The C++ implementation is simply called Eth. If you want added security by running two different implementations in parallel or are serious about GPU mining, then the C++ "Eth" client is for you. Install Homebrew and then make sure it Continue reading >>

Building And Installing Ethereum Compilers

Building And Installing Ethereum Compilers

Building and Installing Ethereum Compilers I recently created a screencast that describes the process of making two of Ethereums language compilers available to a developer. The work is all done at an Ubuntu command line. It starts at the point following a fresh OS install, continues through acquiring the source code and compiling it, and then describes how to install the resulting LLL and Solidity compiler binaries. This article expands a bit on the process illustrated in the screencast. Ill go through the same process, but Ill provide more detail than was possible in the video. Ill be using Ubuntu Server 16.04.2 LTS for this tutorial. For the most part, everything I discuss is portable aross Linux distributions except for updating the OS and installing software. Each distribution has its own package system, so youll have to translate my instructions according to your particular Linux distribution. Well start at a point immediately following the OS install. The first thing we need to do is update the system. You do this by executing apt update and apt upgrade. Note: Im assuming this is all being executed by the root account. If youre not logged in as root youll need to prepend sudo to the following apt commands. Specifying the -y parameter avoids us being asked yes/no questions and allows the installation to continue without interruption.This can be a lengthy process so you may want to prepare a beverage of your choice while you wait. Once the system has been upgraded we need to install some software packages that are necessary to compile the Solidity source code. # apt install -y build-essential cmake libboost-all-dev The build-essential Ubuntu package contains almost everything you need to develop software on Linux. It makes the process of setting up a development e 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 >>

Automation Setup For Cpp-ethereum

Automation Setup For Cpp-ethereum

At the time of writing all of the automation for cpp-ethereum is driven usinga Jenkins instance hosted at . There is a pretty alias to the setup at , but that isowned by Bob Summerwill personally, not by the Ethereum Foundation , and might end up pointing to something else at a later date. It runs in parallel with the Ethereum buildbot instance which is used for Go and Python builds. The fact that we have two different automation systems is not ideal, and is forhistorical reasons. It would make sense for us to consolidate all Ethereum Foundation projects into a single, consistentautomation setup, but that is a non-trivial amount of work. Were talking aboutthat. It will be much easier to assess that when we have completed the repo reorg for the C++ codebase. The current Jenkins setup is missing a canonical continuous integration target ,which is a major weakness. There is no single URL which you can visit to findout whether the C++ builds are working or broken at HEAD. There is not evena URL which you can visit per repository, to find if the individual repositoriesare working or broken. We are also missing automation for webthree-umbrella as a whole, to knowwhether the set of repositories which we are publishing is working or broken. What we do have is automation of our pull-requests. Those are built againstthe develop branches of the repositories which they depend on. There is amechanism for specifying alternative branches for those dependencies, when testingchanges which span multiple repositories. But it is broken . Here are the Jenkins projects for the PR automation. These are triggeredautomatically via Github webhooks whenever new PRs are created, or when the contentof the branches for existing PRs is updated: libethereum-prs - PR testing for libethereum libweb3cor Continue reading >>

Start Mining Ethereum: How To Download And Install Ethminer

Start Mining Ethereum: How To Download And Install Ethminer

Start Mining Ethereum: How to Download and Install Ethminer If youre like many other people who follow the cryptocurrency mining market then you have watched the meteoric rise in the value of Ethereum and Bitcoin mining. Many people are looking to cash in on this market trend through Bitcoin mining for themselves rather than buy the hot cryptocoin through online marketplaces. Ethminer is one of the recommended ways to mine Ethereum but installing it on Windows can be a little more complicated than simply hitting download then install. This step-by-step mining software instillation guide will help you through the process and get Ethminer up and running so you can dip your big toe into the mining pool. Ethminer requires you to build from source. If you have never done this before then the process may seem complicated. However, its really not too difficult to do as long as you follow the steps. A person who is relatively comfortable with working on their computer should be able to handle this. First of all, before you are able to download any cryptocurrency mining software and enter the mining pool, you will obviously need a computer. Visual Studio Express is a free compiler from Microsoft that will work just fine for what you need to do. Next, you need to download your GPU platforms OpenCL SDK. These can be found with a quick Google search. If you have AMD graphics cards then grab the AMD SDK and if you have NVidia cards then you would obviously opt for the NVidia SDK. Finding everything easy so far? Lets keep moving, then. If you dont already have Git you will need to install that as well. Also, you will have to install CMake for Windows as well. Once youve done all the above, use Git to look at cpp-ethereum. Open a command prompt, find a directory, and then type the co Continue reading >>

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.

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 >>

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 >>

Github - Ethereum/cpp-ethereum: Ethereum C++ Client

Github - Ethereum/cpp-ethereum: Ethereum C++ Client

Git and GitHub are used to maintain the source code. Clone the repository by: git clone --recursive cpp-ethereum The --recursive option is important. It orders git to clone additionalsubmodules to build the project.If you missed --recursive option you can correct your mistake with commandgit submodule update --init. CMake is used to control the build configuration of the project. Quite recentversion of CMake is required(at the time of writing 3.4.3 is the minimum ).We recommend installing CMake by downloading and unpacking the binarydistribution of the latest version available on the CMake download page . The CMake package available in your operating system can also be installedand used if it meets the minimum version requirement. The repository contains the scripts/install_cmake.sh script that downloadsa fixed version of CMake and unpacks it to the given directory prefix.Example usage: scripts/install_cmake.sh --prefix /usr/local. The following libraries are required to be installed in the system in theirdevelopment variant: They usually can be installed using system-specific package manager.Examples for some systems: We also support a "one-button" shell script scripts/install_deps.sh which attempts to aggregate dependencies installation instructions for Unix-likeoperating systems. It identifies your distro and installs the external packages.Supporting the script is non-trivial task so please inform us if it does not work for your use-case. We provide prebuilt dependencies to build the project. Download themwith the scripts/install_deps.bat script. Configure the project build with the following command to create thebuild directory with the configuration. mkdir build; cd build # Create a build directory.cmake .. # Configure the project.cmake --build . # Build all defau Continue reading >>
