Geth Change Blockchain Location

Ethereum Data Directory Path Hardwired To C:\users\user\appdata\roaming\ethereum #2828

Ethereum Data Directory Path Hardwired To C:\users\user\appdata\roaming\ethereum #2828

Geth should respect the correct OS roaming path and not default to the C: drive. Ethereum blockchain data is being written to C:\Users\user\AppData\Roaming\Ethereum even when the OS location had moved. The blockchain data was taking a lot of room on my C: drive so I changed the location of the path C:\Users\user\AppData\Roaming (which contains the Ethereum data folder for the blockchain data) to D:\Roaming. When I start the wallet there is a error message that it cannot find the node and so it begins to download the whole blockchain again to the path C:\Users\user\AppData\Roaming\Ethereum As the blockchain will get bigger and bigger a lot of people will want to move the data folder to a bigger drive as the C drive is to small and has all the OS programs and data.

Ethereum Wallet Syncing Problems

Ethereum Wallet Syncing Problems

One of the most common problems with the Ethereum Wallet application is keeping the blockchain in sync with the Ethereum network. This page describes some of the common issues users may encounter while trying to sync the blockchain and potential methods to work around the problems. Note that Ethereum Wallet will not display your account balance correctly when it is not synced fully or correctly. Check that your the clock on your computer is close to real time. Change your system settings so that your system clock is synced to an NTP (Network Time Protocol) server. Slow Syncing Between Blocks 2,283,397 And 2,717,576 You may be encountering some problems syncing Ethereum Wallet (or Mist) to the Mainnet blockchain. A common problem when syncing Ethereum Wallet's blockchain data is that the syncing slows down between blocks 2,283,397 and 2,620,384 due to the attack on the Ethereum network (reference Why is my node synchronization stuck/extremely slow at block 2,306,843? ). The syncing also slows down between blocks 2,675,055 and 2,717,576 due to the state clearing process to remove the 20 million empty accounts created by the network attack. If you have a problem with slow syncing, the easiest way to recover from this slowdown is to remove your blockchain data and restart Ethereum Wallet. Ethereum Wallet will then perform a fast sync which skips over these attack blocks. WARNING: Make sure you back up your keystore directory so you don't accidentally delete your account information. Depending on your operating system, you will find the chaindata subdirectory in: Alternatively, you can run geth removedb to remove the blockchain data. Start Ethereum Wallet. It should now start fast syncing the blockchain data. Alternatively, run geth --syncmode "fast" --cache 1024 console an 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.

Connecting Ethereum Wallet To Existing Geth Client (windows 10)

Connecting Ethereum Wallet To Existing Geth Client (windows 10)

talattufekci{at}gmail.com adresini kullanabilirsiniz. Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third-party interference. Forsecurity purposes, multiple independent implementations were created for Ethereum. The clients have almost identical functionality, so the one you pick is left to personal choice on a platform, language and what your planned use is for the network. TheGoimplementation is calledGeth. Geth has been audited for security and will be the future basis for the end-user-facingMist Browser, so if you have experience with web development and are interested in building frontends for dapps, you should experiment with Geth. TheC++implementation is simply calledEth. 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. ThePythonimplementation is called Pyethapp. If you are interested in understanding how it works and how to extend it, the code base of this client is probably the most readable and has a great contract tester library with fast development cycles. These are tools for blockchain developers. The command line tools will allow you to connect your server to or run your application on the main blockchain or your own private blockchain. The ethereum client we choose is geth. Initially, geth would sync and download the complete blockchain. Unfortunately, ethereum blockchain size is nearly 26 GB, and also many problems and sync problems could occur on windows environment. So I decided to run the geth client with the light mode. When we run geth with light mode the blockchain size is 500 MB. Which is fantastic. First of all download geth: I Continue reading >>

How To Run Private Ethereum Blockchain Onwindows

How To Run Private Ethereum Blockchain Onwindows

Decide on two data directory (folder location) for Geth because we want to run two instance of Geth. Here we use /1 and /2 directories. Open a Windows command window at a suitable folder. Copy genesis.json to this location. This folder should be the parent folder of the two data directories mentioned above. [NOTE: all the geth command flags uses double dashes ] First create a genesis block. Open a command window: geth datadir=./1 -verbosity 3 init genesis.json Then open a Geth console, type in the same command window: geth datadir=./1 -verbosity 3 port 30301 rpcport 8101 rpc rpcapi eth,web3,personal,net identity MyNode networkid 2001 console Note: personal management API must be open for communication with Mist wallet; as specified in the rpcapi flag. Keep the command window open. Open another command window, create a genesis block then open a console: geth datadir=./2 verbosity 3 init genesis.json geth datadir=./2 verbosity 3 port 30302 rpcport 8012 rpc rpcaddr 0.0.0.0 ipcdisable networkid 2001 console Note: You can multiple instance of the Geth on different ports using port flag and just run all Geth instance with ipcdisable flag At node 1, at the command window console type: You should see the enode address. Copy that address. For example: admin.addPeer(enode://4c63f59fb01374c40963685ff9df55c84cc7db63deee714bc4a7f7147bd315738[email protected]0.0.0.0:30301) Check that it works, at the console (any or both), type the following command separately (one after another): This will create a new account for each node. You can use this account to send or receive Ethereum tokens. Mining operations will also add this account. You have to remember the to send tokens. To unlock accounts for non-interactive use: To start mining at Get Continue reading >>

Change Path For Ethereum Wallet Folder

Change Path For Ethereum Wallet Folder "chaindata"

Hello, I just started out with Ethereum by downloading/installing the Ethereum Wallet from the Website. (Win7 64bit) First of all I am not sure about the category this question falls into, so I am sorry if I am in the wrong section of the forum... I need to know how to change the standard path to the 'chaindata' folder for my wallet since I do not have enough free space on my system partition (C:) and could not find any (obvious) settings/options/... in the UI of the wallet. I need to move the regular main folder (C:/ ... 'User'/Appdata/Roaming/Ethereum) or just the chaindata folder (?) to another drive since these (blockchain) files would just fill up my system partition. Any ideas on how to do that? I would appreciate any help or tips. Thank you. Continue reading >>

How To Delete Geth Chaindata & Resync

How To Delete Geth Chaindata & Resync

Home Guides Clients How To Delete Geth Chaindata & Resync Go-Ethereum (Geth)is one of the many Ethereum clients . It is developed by developers from the Ethereum Foundation . The core features of Ethereum web 3.0 stack are expected to arrive at Geth first. In this guide, the procedure for re-syncing Gethon Windows will be shown. I am usingGeth 1.5.4 (latest stable version as of 30 Nov) on my Windows 10 machine. Note: If you have not installed Geth, please install Geth using the instructions here: How To Install Geth In Windows . Resync of the blockchain has the benefit of reducing the amount of disk space used by Geth. The deletion of chaindata folder and resyncing of the blockchain will not be needed once Geth has employed state-tree pruning which will automatically archive old blocks to reduce disk usage. Until Geth has included this functionality, the regular deletion of chaindata folder and resyncing of blockchain is recommended to keep the disk usage at minimum. The chaindata folder is located atC:\Users\\AppData\Roaming\Ethereum\geth\. Yes, delete the whole folder. Do not worry. Your Ethereum account will NOT be deleted (they are stored in another location). Step 3: Run Geth with the -fast -cache=1024 flags If you do not know how to set the flags, please usethe instructions here (Under Step 4): How To Install Geth In Windows . Step 4: Wait for Geth to complete the fast sync Fast sync is completed when Geth starts to import 1 block at a time. Continue reading >>

I am running Windows Seven Enterprise: wondering if someone can advise me on the following. I had Ethereum Wallet on C:\ with only 12 GB free. I moved the Ethereum folder to E:\ and tried to setup the blockchaindir on E:\Ethereum Wallet using geth.exe --fast --cache=1024 datadir=E:\Etherdata The proces starts downloading and shows the following error/warning: and then quits / hard stop after like 2 minutes without any clear warning at the following screen: Any advice is greatly appreciated, thanks! Comments are not for extended discussion; this conversation has been moved to chat . 5chdn Mar 18 at 20:25 Cant you just create a link and point your windows directory to the one in E drive Believe by default Ethereum directory is present here C:\Users...\AppData\Roaming\Ethereum Rename the C drive Ethereum directory to something else lets sayEthereum-Backup If everything works fine you can take the decision to remove the Ethereum-Backup directory You can check the size of which chaindata folder as listed below is getting updated or not. You can check the latest file modified date. I believe you might be in the main network (i.e. homestead) due to which it is taking long time to sync. Also check which folder size is increasing. Main Network Data FolderC:\Users...\AppData\Roaming\Ethereum\geth\chaindata Test Network Data FolderC:\Users...\AppData\Roaming\Ethereum\testnet\geth\chaindata You can always start the getch client with a new genesis config file By the way if your intention is to practice Ethereum then you can use Testrpc. Testrpc basically simulates Ethereum block chain. You don't have to wait long for your deployments or synching issues. In addition Parity has developed a new testnet named Kovan which in similar lines much stable and good for developers. Thank you @ Continue reading >>

How To Run Multiple Geth Instances On A Private Ethereum Blockchain

How To Run Multiple Geth Instances On A Private Ethereum Blockchain

A private ethereum blockchain with multiple geth instances can be run over a network or on the same computer. We will explain how to do both, and also how to solve some common issues. We need to create a JSON file, which will represent the genesis block of our private blockchain. This file which we will name genesis.json will be used by all of our nodes, and is in fact what determines which chain that we are on. {"nonce": "0xdeadbeefdeadbeef","timestamp": "0x00","parentHash": "0x0000000000000000000000000000000000000000000000000000000000000000","extraData": "0x686f727365","gasLimit": "0x8000000","difficulty": "0x0400","mixhash": "0x0000000000000000000000000000000000000000000000000000000000000000","coinbase": "0x3333333333333333333333333333333333333333","alloc": {}} The gasLimit allows us to execute contracts, and by setting the mining difficulty extra low we can easily create our own ethers. If you have several computers on a network, copy this file so all of them have the same genesis.json. Each geth instance should be run with the following parameters: geth genesis networkid 321 nodiscover datadir port 30304 console What all the instances will have in common is the genesis path and the network identification. The nodes will only attempt to connect to other nodes with the same network identification, but we are also adding a nodiscover flag to avoid accidentally connecting to nodes outside our network. Each node will have a different data directory where the blocks data is stored and, if running on the same computer, also a different port. So if you plan on launching several instances on the same computer, you will need an empty folder to be used for each of the nodes. If you are running multiple geth instances on a Windows computer, add the flag ipcdisable, to avoid E Continue reading >>

Exceptionally Large Ethereum Blockchain Size

Exceptionally Large Ethereum Blockchain Size

Exceptionally Large Ethereum Blockchain Size I came to notice that my hard drive which is dedicated to blockchains reached maximum capacity and after a little investigation, I discovered that my "blocks" folder in my Ethereum directory weighs 74.5 GB (80,050,787,860 bytes) for 840,984 Files which seems extremely odd. There's also an "extra" & "state" folder which additionally weigh ~3.5 GB and ~13GB respectively. Cryptominingblog created a post a few hours ago stating that Ethereum's directory is about 16 GB so this only adds to my confusion. I invoke the following command to launch eth via a batfile [start eth -d Q:\the.MlNE\Ethereum] within Mist's subdirectories followed by Mist a few seconds later which is of the latest build. Advertised sites are not endorsed by the Bitcoin Forum. They may be unsafe, untrustworthy, or illegal in your jurisdiction. Advertise here. My Ethereum folder (C:\Users\\AppData\Roaming\Ethereum) is 10.4 GB, using the Mist wallet in win7. Almost all of it comes from the chaindata folder from inside. Wow, that's already messed up in itself. But it's even crazier when you consider Ethereum's launch wasn't even 10 months ago . Dash was released over 2 years ago and its blockchain is only 1.8 GB as of this writing. Just sayin'. Guess distributing a glorified calculator all over the world is taking its toll. Nonetheless ETH is gonna have a future on one datacenter or the other... Quote from: ICOcountdown.com on May 10, 2016, 09:48:56 PM It is because all smart contracts are stored in the blockchain. I did recently create a wallet which to my knowledge is a contract of very basic form. I do however remain a little reluctant to believe that my wallet accounts for over 70 GB of data. damn i need to download the wallet but if ur saying its so Continue reading >>

Actually in Windows there's JUNCTION and, just like Linux, you can create a link of the existing data folder to another one (even in another drive) as you see fit. You can download junction from microsoft technet here: . No installation required. So, in this case, you just need to stop geth, move the data folder to another drive/folder/path and create a junction from the original path to the new one. Move the contents of "%USERPROFILE%\AppData\Roaming\Etherium\Geth" to "G:\Data\Geth" and wait for it to finish. Then execute (on a cmd prompt): cd "%USERPROFILE%\AppData\Roaming\Etherium" If you list the contents (dir) it will show something like: 05/11/2017 20:52 Geth [??\G:\Data\geth] Continue reading >>

How To Backup Your Ethereum Wallet And The Blockchain

How To Backup Your Ethereum Wallet And The Blockchain

All About BTC, LTC, ETH mining as well as other alternative crypto currencies How to Backup Your Ethereum Wallet and the Blockchain Just like with Bitcoins wallet.dat file that contains your wallet address and keys and that you need to backup for safety reasons, Ethereum also has a similar wallet file that you should have a spare copy of. With Ethereum the wallet file has a bit weird name and is not just called wallet.dat, but it has essentially the same purpose and the file works essentially the same way as the wallet.dat with Bitcoin and many other alternative crypto coins. Ethereums wallet file is stored in the data directory used by the client to store the blockchain and other files, the default locations for the datadir on different operating systems are listed below. Windows: %USERPROFILE%\AppData\Roaming\Ethereum To get the full path of the data directory on your specific system you can run the geth console and type admin.datadir and you will see a result like on the screenshot above with the full path. Note that the wallet file is not stored in the main datadir folder, but is instead placed in a separate folder under it called keystore. Inside that folder you should see a file with a long name starting with UTC--2015..., this is the wallet file you need to backup. Do note that aside from the wallet file itself you will also need to remember the password (or also back it up along the wallet) that you set when creating your account, without the password needed to unlock it the wallet file wont be of much use. If you are moving your Ethereum installation over to a different computer or want to have a copy on another system for solo mining for example, aside from a copy of the wallet file you may also want to make a copy of the blockchain, so that the geth client w Continue reading >>
