Greg Wright: Relocating The Ethereum (block)chain Data To An External Drive For Linux / Mac Systems

Relocating the ethereum (block)chain data to an external drive for Linux / Mac systems With the ethereum blockchain now over 110GB, locating the chain data to a separate external drive has become necessary for me so just posting the steps taken as well as referencing to the original helpful post for other options that may be more appropriate for others: Soft Linking - chaindata Subdirectory Only Copy your ~/Library/Ethereum/chaindata subdirectory into your new location /Volumes/Drive2/Ethereum/chaindata using the following commands: A copy of your Ethereum chaindata subdirectory will now be located in /Volumes/Drive2/Ethereum/chaindata. Rename your default Ethereum chaindata subdirectory for testing: mv ~/Library/Ethereum/chaindata ~/Library/Ethereum/OldChaindata_to_delete_when_tested Soft link your new chaindata subdirectory back to the default location: ln -s /Volumes/Drive2/Ethereum/chaindata ~/Library/Ethereum/chaindata Test out your Mist browser and delete your old chaindata directory ONLY AFTER your testing is successful: rm -rf ~/Library/Ethereum/OldChaindata_to_delete_when_tested I'm a total novice at using Terminal. I have an external harddrive that I would like to move my Ethereum chain data to instead of having it stored on my mac's local harddrive. How do I do this? Is it possible to do without using Terminal or how do I set up new folder on the external harddrive using Terminal. What should the mkdir command look like? Please help! 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 >>

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 >>

The Endless Node Sync!!! #2466

The Endless Node Sync!!! #2466

Your ETH balance is still viewable on ethereum blockchain browsers like etherscan: etherscan.io/address/0x... Your local node with ethereum-wallet/mist is only accessing the public blockchain and is not necessary for the rest of the network to function. dear sathishvj -- I have the same issue with my wallet and the node never synching, and on top of that no ether I have sent to my wallet address shows up. Can you elaborate on why you say the local nodes "is not necessary for the rest of the network to function." I'm guessing I have received no ether because the download never completes, but I could be wrong of course. Can you help? So I used the myetherwallet.com route to send my ether to a different wallet. Worked just fine, and now I don't have the stress of wondering if I will ever see my ether due to an endless node sync. @matthewleising as a quite crude analogy, think of how email works. Somebody sends you an email while your computer was shut down. Is it still received? Yes, on your email account. But not your computer. You later start your computer, connect to the internet, and now the email sync happens. The email will then show up on your local client. In a somewhat similar way, somebody sending Eth to your account will be processed by the Ethereum network and it will be available against your account. However, your local node might still not have the latest until it is synced with the network. Hey guys, i have kind of the similar problem.. I bought some ethereum and transferred it to my mist wallet, not realising it was still synchronising... Now the Mist Wallet has been synchronizing for 10 days and is roughly at 66%. it moves as slow as one block a second and it already uses about 20Gb of space on my Macbook. I've read many advises on Geth and myethereumwal Continue reading >>

How To Properly Uninstall Ethereum Wallet

How To Properly Uninstall Ethereum Wallet

I hope you guys can help me on an issue I'm having with the ethereum wallet. I downloaded the wallet from the ethereum homepage and quickly noticed that it was slow as hell syncing the blockchain a problem many of you probably know. Because of that I deleted the chaindata folder as suggested in many threads. I still had the problem of a slow sync so I decided to start all over againg, to uninstall the wallet, install it and delete the chaindata folder again. To my surprise after uninstalling the wallet and installing it again I couldn't find the chaindata folder and other folders anymore. The folder structure seems to have changed. There is a chaindata folder, but it is now in the geth folder which wasn't the case at the beginning My folder structure looks like this since then: I think to remember that before my whole uninstall & reinstall chaos the Ethereum folder had more subdirectories in it Or am I just wrong? Nevertheless I would like to know how I can COMPLETELY uninstall the Ethereum wallet and everything connected to it, so that I can atempt to install it properly again (without it missing certain folders).

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 >>

Speeding Up Ethereum-wallet Initial Sync On Macos X

Speeding Up Ethereum-wallet Initial Sync On Macos X

Speeding up Ethereum-Wallet initial sync on MacOS X After experimenting with the Ethereum Wallet client on a linux machine I decided to install on my MacPro with OS X 10.11.5. I installed the latest Ethereum-Wallet 0.8.1 app from github and launched the app. I soon noticed that the sync would appear to freeze at various points and never achieved a full sync. This despite multiple force quits and restarts. After some poking around I found a nice summary of the problem and a workaround I wanted to share. StackEchange is my goto source when I have any problem and it paid off again today. Under the topic Help with slow mist sync I found several good answers and things to try. Caveat: what Im about the describe worked for me, but I am hardly a knowledgable expert and this may be wrong from a technical perspective. It turns out that, using the command line interface Ethereum client called geth, you can initiatea fast sync by setting certain flags when the program is run. Details are here . This will only work, however, if its the first attempt at a sync. I had made dozens of attempts, so I needed to delete all these files. The first thing I tried worked: I went to my user Library folder (Finder>Go>Go To Folder, then type ~/Library and select Go). Once there, locate the Ethereum folder and open it. Delete the folder called chaindata. (Dont worry. This folder will be recreated when you do the faster sync.) To be able to initiate a fast sync using the command line interface tool, we need to know where the geth program is located. What follows is the description for how to do this by user tayvano at the Ethereum StackExchange: Right click on the ethereum-wallet.app and select show package contents Open contents, then frameworks, then node, then geth Then you should right click o Continue reading >>

Ethereum/welcome - Gitter

Ethereum/welcome - Gitter

hi can anyone direct me to a good tutorial of a msi rx 570 bios mod Hi, I have started a single node with mining property enabled on private network and it started generating ethers, even there is not other node. Miner generate ethers only when it receives blocks from other nodes. how a single node in private network can generate ethers? I need help! I transferred funds from liqui.io to my Ethereum Wallet which in connected to the network but my ethereum I transferred won't show in my wallet because I cannot create a wallet because of a NODE error. What to do? I am using the Ethereum GUI after I downloaded the necessary scripts from git. How long does it usually take to create a contract? Haha I made this mistake when I first downloaded ethereum wallet @JosephIanF_twitter . First question, windows or mac? and also, at the top of ethereum wallet GUI, how many blocks does it say you have left to download? so good news is your coin has almost certainly been sent to your account already, and is very safe there. If you want to confirm, look up the address you sent it to on bad news is that youll have to download the whole blockchain before you can access those funds from within Ethereum Wallet. If youre getting a node error, youll need to delete the ~/Library/Ethereum/geth/chaindata folder (on a Mac) and start downloading the chain from scratch. That has your encrypted private key and if you delete that youll never be able to access the funds in that account. ok then what is use case of (--light) light client mode? geth --fast vs. geth --light geth --fast will find the best peer possible at the moment its run, and fast sync by downloading only the block headers & transaction receipts up to that peers furthest synced block. Depending on the best available peer at that time, Continue reading >>

Backup & Restore | Ethereum Frontier Guide

Backup & Restore | Ethereum Frontier Guide

DO NOT FORGET YOUR PASSWORD and BACKUP YOUR KEYSTORE Everything geth persists gets written inside its data directory (except for the PoW Ethash DAG, see note below).The default data directory locations are platform specific: Accounts are stored in the keystore subdirectory. The contents of this directories should be transportable between nodes, platforms, implementations (C++, Go, Python). To configure the location of the data directory, the --datadir parameter can be specified. See CLI Options for more details. Note: The Ethash DAG is stored at ~/.ethash (Mac/Linux) or ~/AppData/Ethash (Windows) so that it can be reused by all clients. You can store this in a different location by using a symbolic link. Sometimes the internal database formats need updating (for example, when upgrade from before 0.9.20). This can be run with the following command (geth should not be otherwise running): Geth's blockchain and state databases can be removed with: This is useful for deleting an old chain and sync'ing to a new one. It only affects data directories that can be re-created on synchronisation and does not touch the keystore. Export the blockchain in binary format with: Or if you want to back up portions of the chain over time, a first and last block can be specified. For example, to back up the first epoch: Note that when backing up a partial chain, the file will be appended rather than truncated.
