How To Sync Entire Ethereum Client In 2-3 Hours For Testnets & Mainnet

How To Sync Entire Ethereum Client In 2-3 Hours For Testnets & Mainnet

Blockchain Council | Blockchain-council.org How To Sync Entire Ethereum Client in 2-3 hours for Testnets & Mainnet How To Sync Entire Ethereum Client in 2-3 hours for Testnets & Mainnet Most of the people spend hours & days to get their Go Ethereum client synced to start the Ethereum or Solidity development . But they face tons of problems in doing that and end up getting frustrated leading to no progress or huge delay in the development . Go Ethereum Client for Mainnet needs to sync the entire Blockchain which is in multiple GBs right now. Not everyone has the 1TB of HD, especially the MacBook owners. Sync is very very slow, for my Ubuntu based machine it took more than a month on EC2 server which has very fast internet. So its not the internet problem. Many sync bugs haltthe syncing leading to start from scratch. Too much confusion regarding on which testnet the node is running when the network is switched to Testnet as there is no clear name. Ropsten, Kovan, Rinkbey are some of the testnets which are good for the testing. Ethereum & Mist wallet does not show you the name of the test net easily. If all the above issues are frustrating you then you must switch to Ethereum s Parity node which is designed to overcome these issues. This not only syncs everything fast but also gives you very nice Dapp browser & web interface to interact with the Ethereum network along with other powerful features. Parity is the Ethereum node designed to overcome many of the issues which exist in the other Ethereum clients & wallets (Ethereum & Mist wallet ). As per their website fastest and lightest Ethereum client and integrated it directly into your web browser . Using it you can access all the features of the Ethereum network including powerful Decentralised applications and the multit Continue reading >>

How To Serve Up Web Content From Ethereum Part 4 Ethereum Mining On Testnet

How To Serve Up Web Content From Ethereum Part 4 Ethereum Mining On Testnet

How to Serve Up Web Content from Ethereum Part 4 Ethereum Mining on TestNet This tutorialis part of a series of blog postson getting a web page on your web server to communicate via web3 with your Ethereum test network on localhost. post, we created the first block in our testnet using a CustomGenesis.json. In the CustomGenesis.json, we set the difficulty attribute to a very low value, which will enable us to mine some Ether on our testnet quickly. In this tutorial, well describe how to mine for Ether on your testnet. In your Terminal, run the following command to create a new account on your testnet. All of the arguments should look familiar. Pay special attention to the account new, which will create a new user. Joels-MBP-4:Clients joelgarcia$ geth --networkid 200 --identity node1 --verbosity 3 --nodiscover --nat none --datadir=~/myBlockChain/node1 account new After you enter the password for this new user, youll be provided with the unique id for your new user. Copy and paste the address to a safe place. Address: {446e063b51d75ef76ab66c2307e04ced44f39ea6} You should also be able to see this user in your file system by opening up Finder to your myBlockChain directory. Next, were going to start up geth. Were going to start up geth to enable RPC so that Mist and our web pages in the future can access geth. geth --networkid 200 --identity node1 --datadir=~/myBlockChain/node1 --rpc --rpcaddr "127.0.0.1" --rpcport "8545" --rpccorsdomain "*" Most of the parameters should look familiar. Weve added arguments to enable RPC to enable remote procedure calls to 127.0.0.1, localhost, over port 8545, for all domains. You would not want to run this for a production environment as youre enabling any domain to access via RPC. In the subsequent results, you should see that the testnet Continue reading >>

How To Do An Ethereum Transaction, & Check Your Balance? | Cryptocompare.com

How to make an Ethereum Transaction, & check your balance? Once you have managed to set up an Ethereum Miner using either your GPU or your CPU its time to start checking your balance and start trading. Were going to show you how you can check your balance in Command Prompt, how to convert between all the different values of Ether , such as the base unit Wei, and how to make your first transaction! Once you have set up your miner via running the Geth program and Ethminer program (see our guide here on how to get started), you need to open up a third Command Prompt Window. Step 1: This can be done by right clicking on the command prompt in the taskbar at the bottom of your screen and then clicking on the command prompt that appears at the top of the menu. A third command prompt should now be open. Step 2: You now need to tell this Command Prompt where to look to get up and running. Usually the command Prompt window opens looking at your user profile. If this is the case you need to tell Command Prompt to go to wherever you installed geth. In our guide we installed it straight on the C Drive so we need to tell command prompt to get back to the C Drive which we do by typing in cd C:\ and pressing enter. Step 3: You then need to tell Command Prompt what to do. In this case you need to tell it to attach to Geth. So all you type in is geth attach which should look like this C:/>geth attach and then press enter. You now have a console up and running talking to geth so you can start asking it questions or telling it to do things. Remember for"geth attach" to work you need to have anotherCommand Prompt Window runningwith "geth --rpc". If you want to find out your address you type in eth.coinbase. This should look like this C:/>eth.coinbase. Press enter and you should see your ad Continue reading >>

Install Ethereum Wallet

Install Ethereum Wallet

Tutorials and jobs for Ethereum enthusiasts. If you dont have a clue about what is Ethereum or a smart contract, you should first read what is Ethereum . The fastest way to get started with Ethereum smart contract programing is Ethereum Wallet. Its a native application available for Windows, MacOSX and Linux. You can download it from the Github project . Before anything, Ethereum Wallet needs to connect to the block chain and synchronize. Once the sync is done choose the test network. On the test network any transaction will be done with test Ethereum so it does not cost you anything to develop. Keep in mind that while you are on the test network your contracts wont be accessible from the normal Ethereum network. Then you have to choose a password and dont forget it. You dont have to worry too much as the password will only affect the test network. Once this is done you should see the Ethereum Wallet main screen displaying your account address and current balance which should be 0. On the test network you can easily get Ethereum by selecting in the menu Start mining. Let the app run a little and youll see Ethereum in your account. It can takes around an hour to get your Ethereum. In the future, you will need a small amount of Ethereum to deploy your smart contracts to the blockchain and interact with them. You can now start writing your first smart contract . Continue reading >>

Transactions Web3j 3.1.1 Documentation

Mining it yourself in a private environment, or the public test environment (testnet) is verystraight forwards. However, in the main live environment (mainnet) it requires significantdedicated GPU time which is not likely to be feasible unless you already have a gaming PC withmultiple dedicated GPUs. If you wish to use a private environment, there is some guidance on the Homestead documentation . To purchase Ether you will need to go via an exchange. As different regions have differentexchanges, you will need to research the best location for this yourself. The Homestead documentation contains a number of exchanges which is a good place to start. There are a number of dedicated test networks in Ethereum, which are supported by various clients. For development, its recommended you use the Rinkeby or Kovan test networks. This is because theyuse a Proof of Authority (PoA) consensus mechanism, ensuring transactions and blocks are created ina consistent and timely manner. The Ropsten testnet, although closest to the Mainnet as it usesProof of Work (PoW) consensus, has been subject to attacks in the past and tends to be moreproblematic for developers. You can request Ether for the Rinkeby testnet via the Rinkeby Crypto Faucet, available at . Details of how to request Ether for the Kovan testnet are available here . If you need some Ether on the Ropsten testnet to get started, please post a message with yourwallet address to the web3j Gitter channel and you will besent some. In the Ethereum test environment (testnet), the mining difficulty is set lower then the mainenvironment (mainnet). This means that you can mine new Ether with a regular CPU, such as yourlaptop. What youll need to do is run an Ethereum client such as Geth or Parity to start buildingup reserves. Further ins Continue reading >>

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 >>

Mining - How To Get Ether On Public Testnet? - Ethereum Stack Exchange

I am a newbee to Ethereum and doing some research. I have installed the Ethereum Wallet app and synchronized the testnet. However, to deploy my first contract in testnet, it requires some Ether, so can someone guide how to get that? I have tried to mine in testnet but unable to earn anything yet. So, are there any other ways? Could you provide more details about the outputs you got when you started mining? I guess the accounts in test-net are pre-allocated with 10 ether each. Check this for getting more ether. galahad Jun 29 '16 at 15:45 1) Instant: an ether faucet here: 2) An hour or two: Switch on Mining from the menu Develop > Start Mining (Testnet only) or Command Shift M You'll instantly have 1 ETH for each address you send to the faucet, and 20 or 30 test ETH from mining in a few hours at least. 1) did not work for me - no ETH in my wallet even after 10mins david Aug 1 at 23:46 In Ethereum-Wallet, there is an option for CPU mining in the Develop menu. Use it to mine ethers (and win ethers). If you can't mine, you should have a problem (probably network). On Homestead (the production network), cpu mining is inefficient. Otherwise, i recommend you to create your own private blockchain. You could use our script to build one in two lines: With this script, you install a blockchain and can use Ethereum wallet. you could get ether on the testnet simply by using Metamask plugin. first install metamask plugin from here . then follow the steps shown in the following picture : 2- press the ropsten test faucet button : 3- you will be redirect to then request your free ethers.

Howto: Set Up An Ethereum Private Local Testnet

Howto: Set Up An Ethereum Private Local Testnet

Crypto, Products, and other Random Thoughts HowTo: Set up an Ethereum private local testnet howto blockchain ethereum guide osx crypto Ethereum is a decentralized blockchain platform for smart contracts. The protocol is designed in such a way that we can run Turing-complete (arbitrary length) applications. In this guide, we will go over how to set up our own private local testnet (Mac OS X). Questions, comments, and suggestions for improvements are always welcome. Anything published on the Ethereum public mainnet is immutable and consumes gas (Ether) to execute, which can be costly for testing purposes. Having our own Ethereum testnet allows us to test any smart contracts before we deploy it to either a public testnet or the public mainnet, which means we can catch as many errors as possible. It also happens to be a great learning experience. Guides already exist but are outdated or incomplete From my research there are three guides that seem to be the most authoritative and useful on setting up a testnet, listed below in #References . If we combine together the three guides and a few of the StackExchange solutions, then we arrive at this guide. There's lots to learn in this post. To help you remember, try my app Harvest : Take Notes and Learn Passively. You can write or highlight any notes, save them, and automatically receive reminders on an optimal learning schedule. There are a few steps we have to do first to get the necessary tooling. The easiest way to get set up with the Go implementation of Ethereum (the most popular and well-supported) is to use Mac's official unofficial package manager brew: brew updatebrew upgradebrew tap ethereum/ethereumbrew install ethereum Most of us will be running this on our laptops.

Creating A Private Chain/testnet

Creating A Private Chain/testnet

This guide is here to help you set-up a private blockchain in Ethereum using Geth. Information that helped me compile this guide: Tasha at Tech Lab has an excellent write up on the Ethereum genesis block and creating a private test network . Please go there for more detailed information about custom genesis blocks and what some of the lines in a custom genesis block mean. Ade Duke also has a great private Ethereum chain guide that helped me write this article. Geth is the CLI Ethereum client that runs on Windows, Mac, and Linux platforms. Geth is widely used to interact with Ethereum networks. Ethereum software enables a user to set up a "private" or "testnet" Ethereum chain that is separate from the main Ethereum chain. This is useful for testing distributed apps built on Ethereum without having to expose your apps or trials to the real Ethereum network using real Ether. You either pre-generate or mine your own Ether on your private Ethereum chain, so it is a much more cost effective way of trying out Ethereum.What are the components that tell Geth that we want to use/create a private Ethereum chain?The things that dictate a private Ethereum chain are: The Genesis block is the start block of the Blockchain - the first block, block 0, and the only block that does not point to a predecessor block. the genesis block is hard coded into clients, but in Ethereum it can be whatever you like. This gives us lots of options to create a customized, private blockchains based on our needs. Ethereum's consensus algorithm ensures that no other node will agree with your version of the blockchain unless they have the same genesis block. { "nonce": "0x0000000000000042", "timestamp": "0x0", "parentHash": "0x0000000000000000000000000000000000000000000000000000000000000000", "extraData": Continue reading >>

Your use of Stack Overflows Products and Services, including the Stack Overflow Network, is subject to these policies and terms. A private testnet is your own personal, local-to-your-machine blockchain to mess around with. Publishing to the public chain is slow and creates bloat. Plus, you have to use real ether to do anything. A private test net avoids these issues. Setting up a private testnet is easier than youd think. geth --rpc --rpcaddr "127.0.0.1" --rpcport "8545" --dev --mine This says, start a geth instance with JSON RPC (for web3.js interaction) at the given IP and port, create a private chain and start mining it. In the log, you should see lots of the hammer icons, signifying that youre mining your private chains blocks. (CPU-only mining is sufficient because the difficulty begins so low.) When you type geth attach per usual in another terminal window, youll see that all of your accounts balances are zero except your coinbase which is rapidly filling up with fake ether. Dont worry. Your accounts arent really zero. All their real values will be there if you connect to a real geth instance and the public blockchain. Now you can interact with your private test net just as you would the public one. Continue reading >>

The genesis block is the start of the blockchain - the firstblock, block 0, and the only block that does not point to a predecessorblock.

Thus you are advised to set a custom --datadir to keep the public networks chaindata from bing reset. Command line parameters for private network There are some command line options (also called flags) that arenecessary in order to make sure that your network is private. We already covered the genesis flag, but we need a few more. Note that all of the commands below are to be used in the geth Ethereum client. Use this to make sure that your node is not discoverable by people who do not manually add you. Otherwise, there is a chance that your node may be inadvertently added to a strangers blockchain if they have the same genesis file and network id. Use maxpeers 0 if you do not want anyone else connecting to your test chain. Alternatively, you can adjust this number if you know exactly how many peers you want connecting to your node. This will enable RPC interface on your node. Thi Continue reading >>

Choosing The Right Digital Wallet Before Building A Crypto-mining Pc

Choosing The Right Digital Wallet Before Building A Crypto-mining Pc

Choosing The Right Digital Wallet Before Building A Crypto-Mining PC Before you can start mining any cryptocurrency, you need a wallet address to store it in. There are a variety of wallet options, including the official Ethereum wallet (available on Ethereum.org), but that option consumes lots of storage space. The official wallet (for any crypto-coin) downloads a copy of the entire blockchain ledger to your hard drive, to the tune of several gigabytes of capacity, and a long download wait time. Local wallets are relatively safe, but you must backup your wallet file manually. If your hard drive fails and you dont have a copy of the wallet.dat file, youll lose all your crypto coins. If you dont want to waste time and hard drive space downloading the blockchain ledger, or you have a terrible track record with backups, consider a cloud-based coin wallet such as the one that Coinbase.com offers. A cloud-based wallet is easily accessible, there are no issues with downloads or drive space, nor with hardware failures. There are downsides: When you set up a Coinbase wallet, Coinbase retains the private key. If the company decides you shouldnt have access to your funds, it can revoke the account and you'd lose your coins. If you plan to invest in multiple crypto-currencies, consider a multi-coin wallet. Each crypto-coin needs a separate wallet, and you have to keep the client software up to date so you can access your holdings. Its much easier to run one application with addresses for multiple currencies than running multiple wallet apps in the background. I chose Jaxx Wallet . It's a free app for PC, Mac, iOS or Android. The software supports a variety of altcoins, including Bitcoin, Ethereum, Ethereum Classic (a forked branch of Ethereum), Dash, Litecoin, Zcash, REP, and RSK Continue reading >>
