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 >>

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/mist - Gitter

Ethereum/mist - Gitter

Sweet, think as more nodes get up on the hardfork, things will speed up for everybody. Does anyone know why my mist UI is not fully loading? hmmm, could be that bad Mist file issue that has been mentioned before, mist.lciob or something like that, if you scroll up the file is listed @andrew-es , people have been having to delete the file and restart Mist. mist.lokidb is the file name in Mist folder @agnewpickens Just tried that, unfortunately that didn't help. The console in that image is however reporting 3 errors if anyone knows whether they could play a role in this or not Try to click in the upper right corner maybe the button is not showing. The console errors are not important Found a solution. Delete Mist folder completely. Load Mist. Works now Ethereum Wallet keeps seeming to lock up today. What does you node.log say? Is geth still syncing in the BG? It looks up if it's processing logs from, e. G. the DAO withdraw contract Just let it sit for a while just let it sit for a while Ok, thanks. The DAO strikes again. Any way to unwatch a contract without the UI working? As a last resort you can use 0.6.2 / this Yeah but 0.6.2 will not run the current chain. So only use it to unwatch ^^^ Good to know, DAO Watch has really slowed down my 0.8.1 Yeah very helpfull thanks, did a bit of housekeeping. hello :) How does Mist recognize a token contract? (Custom Token under Contracts) does anyone here have experience deploying Mist on Linux? the deployment steps in the wiki are for OS X only @jesuscript hey, there are currently no PPAs for Mist, only AUR for archlinux. Could you point me to the wiki you found? I will try to update/consolidate the info. @luclu i was wondering about the build environment i mean, if I run a linux box (e.g. ubuntu), is there a way to build Mist f Continue reading >>

Mac Osx - How Do I Recover The Disk Space Space After Uninstalling Ethereum Wallet On Os/x? - Ethereum Stack Exchange

How do I recover the disk space space after uninstalling Ethereum Wallet on OS/X? Just to preface, I am somewhat new to Ethereum, and I'm trying to learn my way around. So I recently downloaded the Ethereum Wallet from the Ethereum website, and I subsequently uninstalled it once I realized that it was downloading the entire blockchain, which I just don't have space for on my machine (on a mac). However, I noticed that I am missing about 9 gigs of space on my machine even after deleting the app and the data. Any idea why I'm missing space? Any files I should delete? On OS/X, Ethereum Wallet places the blockchain data in the chaindata subdirectory under $HOME/Library/Ethereum/geth. You can remove the chaindata subdirectory. If you want to save any private/public keys, copy $HOME/Library/Ethereum/keystore and it's contents to a backup location. If you have no use for Ethereum Wallet on your computer, you can remove the data from your computer (after saving your keystore if necessary) by deleting $HOME/Library/Ethereum and it's contents. Thanks for your response. It's very odd, but I did all those things and I'm still missing like 9 gigs of space. Really bizarre. Thank you though. w23 Mar 14 '17 at 3:38 Have you emptied your Trash folder? BokkyPooBah Mar 14 '17 at 3:39 Yes... It's really bizarre. w23 Mar 14 '17 at 3:54 Start terminal. Go to $HOME/Library . Type du -hs * to find the large directory. Go into the large directories and use the same commands to find where the large files are. If you cannot still find where the space went, start at '/' . BokkyPooBah Mar 14 '17 at 5:50 A little late to the game, but after deleting large files from mac, I learned that if one uses time machine, its local cache can be cleared to recover space. e.g. "sudo tmutil disablelocal" watch y Continue reading >>

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 >>

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. Import binary-format blockchain exports with: See for more info And finally: DO NOT FORGET YOUR PASSWORD and BACKUP YOUR KEYSTORE 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 >>

(This page covers an older version: Version 0.3.8, Beta 5. For a more recent version, select from the menu.) Versions of the Wallet App are available for Linux, Mac OS X, and Windows. For the Wallet App to work, it will need to connect with a running, fully synced Ethereum node. The Mac, Linux 64Bit and Windows 64Bit versions come with a bundled Ethereum node, the Golang implementation called Geth. As this user guide is targeted at non-technical users who will not want to separately install a Geth node, only these versions with the bundled node are covered in this guide. Note: The Mac OS X and Win 64Bit versions also include Eth, the C++ Ethereum client. However, only Geth is covered here. Downloading the Wallet App involves syncing a full copy of the Ethereum blockchain on your computer, requiring almost 6 GB of disk space as of early January, 2016. As such, be prepared to wait about an hour for the initial syncing process to complete. Note: In this example, I work through the installation of the Win 64Bit version. Select the version you require from the available options on this page . For this example, I select: Ethereum-Wallet-win64-0-3-8.zip After you unzip the downloaded folder, look for and launch the Ethereum-Wallet application/program file. When the blockchain has fully synced, you will see the Wallet Apps sparse (but beautiful!) opening screen: Note: If you previously downloaded and used a version of this Wallet App, you may see one or more Accounts displayed in the opening screen. This is because, when you update the Wallet App by downloading a new version, the app will continue to use data from the older version. More on this later. Most Wallet App operations will fail if your node is not fully synced, that is, if your copy of the blockchain is not up-to-da Continue reading >>
