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 >>

Ether Mining With Your Own Hardware | We Will Show You How To Do It

Ether Mining With Your Own Hardware | We Will Show You How To Do It

Anyone can buy Ether. We want to earn Ether ourselves and besides that, make the Ethereum network safer. Ether Mining is rewarded with 3 Ether each block. But this is not it. Furthermore, the gas which exists of fees for transactions and contracts, is declared in addition to these 3 Ether per block. It is assumed that, as time goes by, the reward of the gas with 3 Ether per block will exceed a lot. But it is getting even better. Further Ether for uncles will be declared every now and then, in addition to the 3 Ether per block and the reward for the gas. Which means, another up tp 7/8 of the 3 Ether from the block on top. So many Ether After all, we want to point out that Ether solo Mining requires a lot of luck. The computing power of the entire Ethereum Network is tremendous and therefore it will be pretty hard to snatch a block. Still, Ether solo Mining is an exciting thing. In the following, we will show you all the essential equipment you need for a successful start with Ether solo Mining with windows. 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 >>

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 >>

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 >>

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.

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 >>

Want to install CPP 1.2.7 on a Lubuntu 14.04 32-Bit system. It says to do that from terminal, but do I do that from the Geth console in terminal or just straight from the terminal. The guide I downloaded doesn't use "sudo" so I am wondering. This is our guide ... ... and these are commands to execute in a bash shell, or similar, not inside the geth Javascript console. @slothbag I'll just install myself right now, and see if I can replicate. Just to verify, you run this Windows installer, right? And you are sure that the solc you are running is in C:\Program Files\cpp-ethereum? yes, that is the guide I have, but lower down, it says to use "apt-get install cpp-ethereum" and I am wondering if I need to put "sudo" in front of that command or if it runs once I open Geth console. @bobsummerwill OK, will try from terminal, but if it doesn't run, will use "sudo" in front of command @agnewpickens sudo is just to do with whether you are running the package install using your own user account, or with elevated permissions globally. Looking again at , they all have sudo. Where is the line you are seeing WITHOUT that? Might just be a bug in the docs. From those instructions, I think we're going to want everything to be sudo'd. C:\Program Files\cpp-ethereum> solc --versionsolc, the solidity compiler commandline interfaceVersion: 0.3.4-dab8902/RelWithDebInfo-Windows/msvc/Interpreter had to use "sudo" and it says I have unmet dependencies after installing repository. And to be clear, @agnewpickens, was that an UPDATE, or a fresh install? Have you do the usual update/upgrade dance? just getting this machine up, it is running Geth 1.4.6 and Wallet 7.4 been having issues on sync around block 60-70K, errors and such OK ... please could you log a new Github issue for this against .

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 >>

IMPORTANT - If you have ever contributed code to cpp-ethereum, please look through #530 - Get to clarity on licensing and copyright and add an e-mail address for yourself to the pirate pad . Remove the Frontier canaries which we forgot to remove. This is the "Theymos fix" . Fixed security issue which meant that accounts stayed unlocked once their password has been entered until cpp-ethereum was closed. Reported by WhySoS3rious Switched to using the evmjit repo as a sub-module. Pawe Bylica is actively working on the JIT again. Enabled warnings-as-errors on all platforms. Merged most of the GCC and Clang compiler settings, for ease of maintenance Defaulted build configuration to RelWithDebInfo Support for Visual Studio 2015. We will be dropping VS2013 next release. Support for statically linked builds on Arch Linux and for partially-statically linked builds on OS X, from rainbeam . Support for building against musl C standard library. We previously implicitly assumed GLIBC, from rainbeam More work on Intel compiler support, courtesy of Robert Pancoast Fixed GCC 6 warnings for Arch Linux, by Robert Edstrm , Robert Pancoast , Christian Reitwiener , Bob Summerwill , mWo , rainbeam , WhySoS3rious The DMGs in the last few releases contained stale .app files for Mix. That has been resolved in this release. Other than that, the only change was a minor fix from RJ Catalano to match solidity changes. Many, many people are having issues with Mix crashing-at-boot on OS X. We are aware, but short of people to troubleshoot. If you can help, please do come to the mix gitter channel and we can coordinate. This release mainly makes libraries more flexible in that it allows internal functions to be called.

Beginner's Guide To Ethereum Mining In 2017 - How To Mine Ethereum On Your Pc?

Beginner's Guide To Ethereum Mining In 2017 - How To Mine Ethereum On Your Pc?

Last updated on August 15th, 2017 at 11:06 pm Getting Started with Ethereum Mining the video guide The good news is that getting started with Ethereum Mining is now easier than ever. You do not need to download the full Ethereum blockchain, which is now over 20+ GBs and still growing! You also do not need to manage clunky command line miners with manual instructions. For purposes of this guide, we are going to do a detailed walk-through of setting up and using the very popular Claymore Miner. Get the current version here from Claymores original Bitcointalk thread and then follow along with the steps in this video. The whole process of getting a wallet setup, downloading your miner, configuring things in Windows and setting up your batch file to run should take less than 10 minutes: If youre new to mining Ethereum , this guide covers all the important facts in a simple, low-jargon way. Lets start with some short answers to common questions about Ethereum mining: Q: Whyshould Imine Ethereum tokens (aka ether or ETH)? doesnt mining Ether take up a lot of electricity? A: If done properly, more money is earned by selling mined ETH than is spent on electricity. In other words, its profitable! You can check out the profitability with our Ethereum mining calculator . Q: Can I mine with my CPU (Personal computersprocessor) instead ofan expensive graphics card (GPU)? A: GPUs are so much faster that CPU-mining is no longer profitable or worthwhile. Even entry-level GPUs are about 200 times faster than CPUs for mining purposes. Q: Whats the best GPU to use for getting the most ETH for the least electricity? A: AMD cards tend to edge out similarly-priced NVidia cards in terms of efficiency. We cover the best cards to get under the heading GPU Hardware further down in this post. Q: 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 >>

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 >>
