Ethereum Wallet Blockchain Download Taking Ages - Ethereum

Ethereum Wallet Blockchain Download Taking Ages - Ethereum

Ethereum wallet blockchain download taking ages 2 days ago I downloaded Ethereum Wallet and it's still downloading the blockchain. Often it can only find 1, maybe 2 peers. Oh and sometimes it says it's connected to one peer, but it's downloading absolutely nothing for hours. This is the problem - you should have many more peers - there must be something wrong with your local set up - what version of geth/ Mist do you have ? I have Ethereum wallet version 0.8.10.1708 What version of geth is running in background ? Open command window and type geth --version If you know how to use the command line, there are much faster ways to sync a full node. With parity (my client of choice), it is parity --warp. With geth, I believe it is geth --fast. Geth also has a light client, which you can use with geth --light. This will sync in less than a minute. Your other option is to use a zero client, which requires no syncing at all. Check out myetherwallet.com or metamask.io Woah! Did not know that. I'll probably still continue to use it because I always kinda feel like Picard saying "engage" when I turn it on. How long should geth --fast take? It took me 5 hours before I stopped. I have a decent internet connection so I can't really tell what the issue is. You are not the only one with this problem, it's repeatedly posted here and elsewhere. We REALLY need a decent, reliable, secure wallet like Electrum for BTC. Until then you have two options, wait for the blockchain to finish or start again using the fast option. Good luck. What's the difference between BTC wallets and ETH wallets? BTC ones sync in less than 20 mins. I'm guessing that BTC ones have a lot more to download (assuming that age is directly proportional to length of blockchain) so shouldn't those take longer? Light wallet Continue reading >>

Ethereum Wallet Review Mist

Ethereum Wallet Review Mist

JP Buntinx June 25, 2017 Reviews , Wallet Not too long ago, we discussed a lot of Ethereum wallets people can use to store their coins in a safe and secure manner. One of the wallets on that list is the official Mist wallet for Ethereum, which has undergone some big changes over the past few months. Now is a good time to look at what this wallet looks like and whether or not it is suited for most people. The Mist Wallet for Ethereum Yay or Nay? From a security point of view, it makes a lot of sense to download the Mist wallet . It is the official Ethereum wallet client developed by the same people who are responsible for moving the Ethereum ecosystem along. Unlike some other solutions, this is not a third-party wallet. Instead, Mist is designed to put the user in full control of their funds at all times, which is nice to see. Moreover, the Mist wallet supports two types of wallet solutions, which is quite interesting. On the one hand, Ethereum users can set up a simple wallet, which does everything you would expect. The Mist wallet has a very nice user interface, which makes it quite easy and appealing to use. Do keep in mind this is a desktop client, which means users need to download it onto their computer manually. Mist also provides users with a multisignature wallet, should they require the extra security at any given time. As beautiful and convenient as the Mist wallet may sound, it is not without (significant) drawbacks, though. Mist is not a lightweight client by any means. This means users are forced to download the entire Ethereum blockchain before they can use the wallet. Right now, that blockchain is quite large, and it may even grow to 1 terabyte in size over the next year or so. Ethereum users need a lot of free hard drive space to synchronize with the bl Continue reading >>

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 >>

Synchronization - Time To Download Blockchain These Days? - Ethereum Stack Exchange

Synchronization - Time To Download Blockchain These Days? - Ethereum Stack Exchange

I'm trying to download the blockchain using geth. I started it around 10 days ago, without the --fast parameter. After about 7 days it got corrupted at block 1.800.000 or so. Then i tried starting over using the --fast prefix, it went a lot faster at first but now it is taking 5-10 minutes per block while previously it used to take 8 seconds per block. What causes this difference? Not sure if i'm doing something wrong or if it's normal to take multiple weeks to download the whole blockchain? When it comes to Ethereum, there are two things you got to consider unlike most cryptocurrencies: Your download speed, and your processing speed. That difference you're seeing is most likely because your node is stuck processing "busier" blocks that carry more transactions and contracts. Moreover, Ethereum has had to deal with spam attacks before , and your client still needs to process the transactions related to these attacks at some point or another. As a reference, I was unable to get much luck with geth at all, as my connection is not too reliable and as a security measure, upon the tiniest sign of trouble, the fast sync will be cancelled and geth will fall back to full block verification, to the point I ended up using Parity in Geth compatibility mode so I could keep using Ethereum Wallet. parity --geth --warp took just about two days or so to get the headers for the latest blocks so I could at least see the latest transactions, and around a week to process all blocks on my measly 3Mbps connection.

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 >>

Ethereum Node Needs To Sync, Taking Too Long #2508

Ethereum Node Needs To Sync, Taking Too Long #2508

It gets to the point where it downloads more blocks before it stalls and I have to usually force quit the app and restart it to get it going to download more blocks. My hard drive has more than enough space so don't think this is the issue. I've tried to run it all on it's own so don't think it is a computer resource issue. i'm seeing the same issue. i left my computer on for about 18 hours and still under 2.5 million blocks. i'm just recently learning about how all this works, so please don't mind my question if there's an obvious answer, but is there a reason wallet nodes on the network need the entire chain, instead of say, the most recent million? and then miner nodes could include the full chain for integrity Seeing a similar issue, blockchain takes a long time, gets nearly to 100%, then starts the sync over again. I tried deleting the l%APPDATA\Roaming\Ethereum\geth\chaindata directory and restarting. That made the sync download run faster, I assume because it was doing a --fast sync, but it still fails to complete. I am using a Windows 10 PC, running 0.8.8 so I will update the build and try again just in case that's contributing. I deleted my chaindata and am trying to get my wallet to fast sync. I am using a linux soft link to save my chaindata on a different hard drive. I am usingethereum wallet --fast --cache=1024 to run the wallet. Is that effective, or do I have to run geth first with the command? I am having an issue where my node is perpetually 50-100 blocks or so behind. I am not seeing any peers listed in the wallet GUI. Any ideas how to fix this? It also seems that if I leave the wallet in the loading screen (ie do not click 'launch application' to run the GUI) it syncs faster. Has anyone else noticed this? The lag of the network to i/o the disk is mea Continue reading >>

How Long To Download Ethereum Blockchain?

How Long To Download Ethereum Blockchain?

How long to download Ethereum Blockchain? So I downloaded the Ethereum-Wallet(MIST) because I want to get into altcoins as well as Bitcoin. When I started the Wallet, it started downloading the Ethereum Blockchain. This is more then 24h ago at it seems the closer I get to finish downloading the whole thing the slower the download I mean it's getting ridiciulous with this massive blockchain downloads and the wiaitng time, especially because I download around 15GB so far. 15GB I could download in less than an hour so why does this take so long with these blockchains I thought its like a p2p download, And o another note the number of total Blocks seem to be changing while downloading. I wouldn't have been surprised if it would grow bigger because of more transactions in the blockchain etc. but it is jumping frim 1,480,000ish to 1,580,000ish Blocks... back and forth...

Frequently Asked Questions

Frequently Asked Questions

How long should it take to download the blockchain? The Ethereum blockchain is constantly growing, and is nearing 10GB as of March 2016. The amount of time it will take to download depends on the amount of peers you are able to connect to, your internet connection speed, and other factors. See the download-the-blockchain-faster section for tips on syncing the blockchain more quickly. How do I get a list of transactions into/out of an address? You would have to pull the transactions manually out of the blockchain to achieve this. Alternatively, you can rely on third party explorers APIs like Etherchain . For contract execution transactions however, you can filter the contract logs to achieve this. Can a transaction be sent by a third party? i.e can transaction broadcasting be outsourced Technically yes, but there is an important restriction as opposed to bitcoin signed transactions: in ethereum the transaction has a nonce (more precisely, each account increases a counter when sending a transaction based on how many transactions total have been sent. If 3 transactions have ever been sent from the account, the account nonce would be 3). Can Ethereum contracts pull data using third-party APIs? No, Ethereum contracts cannot pull data from external information sources in this way. It is however possible to push data from external sites (e.g. weather sites, stock prices) to Ethereum contracts through transactions. There are oracle services that are compatible with the Ethereum network that will pull/push data to the Ethereum network for a fee. Is the content of the data and contracts sent over the Ethereum network encrypted? Data and contracts on the Ethereum network are encoded, but not encrypted. Everyone can audit the behavior of the contracts and the data sent to them. Ho Continue reading >>

Downloading The Full Ethereum Blockchain Takes A Fewweeks

Downloading The Full Ethereum Blockchain Takes A Fewweeks

Downloading the full Ethereum blockchain takes a fewweeks Recently I have been working with Ethereum and analyzing its blockchain. I have needed transaction traces (e.g. what EVM instructions are executed by a transaction) for the research problem Im working on. geth, Ethereums most popular (Go) implementation, supports a method called traceTransaction which computes transaction traces. All one needs to provide to the method is the transaction hash. By default, the output trace includes the state of the stack, memory, and storage after execution of each EVM instruction; however traceTransaction also provides a very flexible, JavaScript-based tracing mechanism to retrieve all sorts of other information. For example, one can obtain the current context (storage account) in which a transaction is executing, or its current depth. See more about the traceTransaction function here . While traceTransaction is useful method for analyzing transactions on the blockchain, I quickly learned that it order to execute this method, I needed the FULL blockchain. When running a geth node, there are two different ways of syncing it: via a fast sync or a full sync. For most people, a fast-synced node suffices if they want to mine blocks, exchange Ether, or publish smart contracts on the blockchain. At a high level, fast syncing works by pruning away old states in the blockchain, so that the blockchain occupies less space and database lookups are faster (there is a StackExchange thread discussing the difference between these two options, and a GitHub thread that describes fast syncing in more depth).A fast sync supposedly completes in a matter of hours, and takes roughly 30GB of space (at the time of this writing). However, since traceTransaction may need to look up old states in order to c 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 Ethereum-blockchain Size Will Not Exceed 1tb Anytime Soon.

The Ethereum-blockchain Size Will Not Exceed 1tb Anytime Soon.

The Ethereum-blockchain size will not exceed 1TB anytime soon. Before diving into this article, please read the two disclosures about my involvement (1,2) and the one on data accuracy (3) at the bottom of the article. At least once a month someone posts a chart on r/ethereum predicting the blockchain size of Ethereum will soon exceed 1 TB. I want to take that chance to clean up with some stories around the Ethereum-blockchain size in this article and try to explain why this chart is technically correct, but not the full picture. Let's have a look at this chart first. It shows the complete data directory size of an Ethereum node (red), Geth in this case, and a Bitcoin node (blue), probably Bitcoin-Core , plotted over time. While the Bitcoin graph is moving slightly upwards in a seemingly linear inclination, the Ethereum graph reminds the reader of an exponential growing slope. On Blocks, Block-History, States, and State-History Users accusing Ethereum of blockchain-bloat are not far off with their assumptions. But actually, not the chain is bloated but the Ethereum state. I want to examine some terminology from the Whitepaper before proceeding. Block. A bundle of transactions which, after proper execution, update the state. Each transaction-bundling block gets a number, has some difficulty, and contains the most recent state. State. The state is made up of all initialized Ethereum accounts. At the time of writing, there are around 12 million known accounts and contracts growing at a rate of roughly 100k new accounts per day . Block-History. A chain of all historical blocks, starting at the genesis block up to the latest best block, also known as the blockchain. State-History. The state of each historical block makes up the state history. I will get into the details on t Continue reading >>

How To Fix Ethereum Mist Wallet Never Ends Syncing

How To Fix Ethereum Mist Wallet Never Ends Syncing I had an issue with the Ethereum Mist wallet never finishing syncing the blockchain. Mist just kept downloading chain structure for two days, always stuck a couple of hundred blocks behind the most current one. Download the latest version of Geth and extract it to somewhere like C:\Geth ( ) Run CMD.exe (Command Prompt, the black terminal window in Windows) as Administrator (right-click -> Run as Administrator) Change directory to where you extracted Geth: Run the following command to start syncing the blockchain using the light syncmode: It should now start syncing. After a while (how long varies), you will notice it reaches the current block and becomes less active. You should now be able to run the Mist wallet without issues again. Download and run the latest Mist wallet to avoid other bugs/issues ( ) Hope this helps someone out there with the same annoying issue! Continue reading >>

Ethereum Blockchain Bloat Could Reach 1tb In 2017

Ethereum Blockchain Bloat Could Reach 1tb In 2017

Ethereum Blockchain Bloat Could Reach 1TB In 2017 Blockchain bloat is afflicting Ethereum with a user reporting a download taking more than a week to complete. Ethereums (ETH) blockchain is now larger than Bitcoins at around 180 gigabytes, with experts warning further increases may spell disaster. After one user reported downloading the backlog of transactions for over a week while syncing a node, cryptocurrency commentator and entrepreneur Tuur Demeester highlighted a source giving an overall figure of up to 180 GB. According to one source, the Ethereum blockchain has bloated by +700% in the past 12 months: now about 180 GB. pic.twitter.com/XfH5He4gRL Tuur Demeester (@TuurDemeester) June 12, 2017 Ethereum overtook Bitcoin sometime in February 2017, according to the source data, when both were around 130 GB. Further Twitter commentators added that the problem of so-called Blockchain bloat would be compounded by the fact that the relative free-for-all on Ethereum-linked wallets meant that many users had a considerable number of them. A huge range of altcoins are based on the Ethereum blockchain, many of which continue to see frantic trading activity with the completion of various ICOs . What the future holds for ETH itself meanwhile poses further issues. Continued upward trajectory could see the biggest altcoins blockchain hit one terabyte before 2018, making syncing a seriously unwieldy business. Based on that, the chain is projected to be over 1Tb in less than 12 months. If it continues that growth rate it'll die; space = $$$$ David Keenleyside (@Nuke_Bloodaxe) June 12, 2017 ETH prices meanwhile hit new highs over the weekend, capping a 3000% increase since the start of the year which is doing the rounds across mainstream media.
