Ethereum Wallet Does Not Synch (downloading Chain Structure Without End In Sight) #2749

Version: `0.8.10`OS & Version: osxNode type: `Geth 1.6.6 (Go)`Number of blocks synchronized: 4010159 I'm not a techie but wanted to try and download and synch a wallet to start to learn. It's been three days and the wallet has not synched. The "downloading chain structure" never ends. What options do i have? It usually does take a few hours. But if it's taking too long, you want to check other things like - is a firewall/antivirus blocking anything, are you behind a proxy and can you try on another network, any specific issues shown in the log file? Hey Sathish - i read your earlier responses on the same lines. No firewall/antivirus, no proxy, tried two networks too. No log file issues that i can see. The issue is that it's been 3 days and the chain structure just keeps on growing, just never ends. Same here. It looks like this isn't a priority for fixing or they just can't repro it. It's going to be up to us to fix it or abandon MIst/Wallets in Ethereum. I'm on my third day of trying to download the block chain for my wallet. I'm on Windows 10. I have no firewall/proxy/network issues. Here's the last entries in the log when it's stuck (nothing unusual except the retry): INFO [08-12|12:55:12] Imported new state entries count=1 flushed=1 elapsed=0s processed=19798 pending=3054 retry=1 duplicate=0 unexpected=2 INFO [08-12|12:55:14] Imported new state entries count=384 flushed=420 elapsed=114.308ms processed=20182 pending=3124 retry=2 duplicate=0 unexpected=2 INFO [08-12|12:55:15] Imported new state entries count=384 flushed=404 elapsed=22.045ms processed=20566 pending=2876 retry=2 duplicate=0 unexpected=2 INFO [08-12|12:55:17] Imported new state entries count=384 flushed=386 elapsed=92.248ms processed=20950 pending=2919 retry=264 duplicate=0 unexpected=2 It appears to ge Continue reading >>

Does The Ethereum Walled Download The Whole Blockchain To My Computer? Where Is It Downloaded To, And What Is The Size (as Of April 2017)?

Does The Ethereum Walled Download The Whole Blockchain To My Computer? Where Is It Downloaded To, And What Is The Size (as Of April 2017)?

Does the Ethereum walled download the whole blockchain to my computer? Where is it downloaded to, and what is the size (as of April 2017)? If you download an Ethereum wallet like Mist , then by default you are running the full client, which will download the entire blockchain. The default location of this chain in Windows 8 is: C:\User\\AppData\Roaming\Ethereum\geth\chaindata. As of April 19th, 2017, my blockchain size is 23.5 GB total. If you dont want to download a full client, I would highly recommend Metamask.io . Its a client that will create a wallet for you, but wont download the blockchain. It will also allow you to interact directly with Dapps. Ya, if you want to sync to the mainnet with your Ethereum Wallet you must download the entire blockchain. It saves each block into a folder called chaindata in a location that you specify. If you are a developer you can use APIs like Infura and Web3 to interact with the main Ethereum chain. You also have the option to connect your Ethereum Wallet to the testnet or to a private Ethereum blockchain that you can configure using Geth. Both of these options allow you to develop on a test chain to test applications, without needing to download and store the entire blockchain. You can use this walkthrough to connect an Ethereum blockchain locally , and this walkthrough to connect your Ethereum blockchain using AWS . 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 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 >>

Ethereum Blockchain Size - Crypto Mining Blog

Ethereum Blockchain Size - Crypto Mining Blog

All About BTC, LTC, ETH mining as well as other alternative crypto currencies Ethereums Blockchain Data Getting Close to 30GB The people that prefer to have full control over their Ethereum (ETH) addresses by running a local node with a full copy of the Ethereum blockchain could soon start having free space issues as the storage requirements continue to grow at a rapid rate. The Ethereum blockchain data is already getting close to 30GB in size and thanks to the Ethereum Classic (ETC) you may need to make a copy, so another 30GB of data for the ETC local wallet and blockchain. It may not be that big of an issue if you keep a single large blockchain on your computer, but people that use local crypto currency wallets usually have multiple of these and with the already huge Bitcoin (BTC) data getting close to 85GB in size as well as a few other more established older altcoins the free space required on your hard drive or let alone SSD if you use one can be over in no time Ethereums Blockchain Data Continues to Grow Rapidly in Size It is not even a year since the mining of Ethereums Ether (ETH) coins has started and due to the short block time and the huge user interest the total size of the blockchain data of Ethereum has already grown huge and continues to grow rapidly. The current size of the Ethereum blockchain data files is already over 16 GB and just about two months ago it was a bit over 9 GB . With the increasing demands for storage to host the full blockchain data as a part of a local wallet or a full network node more users might be switching to online wallets and other services that do not require the user to have a local copy of the data files such as exchanges for example. With more users getting into Ethereum the number of transactions on the network is also g Continue reading >>

Ethereum Blockchain Size

Ethereum Blockchain Size

I synchnorized Ethereum blockchain in my AWS Ubuntu 16.04 server with 110GB Hard Disk. The command I used is geth --syncmode=fast --cache=1024 According to bitinfocharts , the total size of Ethereum Blockchain is 103.10 GB total as of today (2017.11.26). After synchronization is completed, I typed dh -h to find out how much disk space it consumed. It is ONLY USED 38GB, which is 1/3 of the blockchain size! From this link , 5chdn answered that the Geth only offers database pruning on initial sync. Is that the reason? what If i want to synchronized full blockchain node? What command should I use to sync the full node? You do have the whole blockchain, you are not missing any information. It's true initial sync is done in "fast" mode and contains pruned information that you don't need. This also means that it's not a bad idea to delete the blockchain data and restart if you are low on disk storage and has been running a node for >6 months. The database will be much smaller (but again they both are full nodes). Thank you for your comment. But, i still don't understand why the blockchain size is a lot different from the bitinfocharts website ( bitinfocharts.com , right now the blockchain size is 121.79GB). If I have the whole blockchain, then i thought it should be closer to 121.79GB. JayB Kim Dec 3 '17 at 4:26 There are many details that I can go into to answer the question you have, but you will find better answers if you search for what the difference between a pruned and archived blockchain is for Ethereum. One analogy is compression. You can have a 10 MB file compressed to 1 MB, you still have all the needed information with the 1MB file (even if pruning is not the same as compression). xgabrielx Dec 3 '17 at 10:30 thank you! I will search more. Basically, since i used 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.

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 >>

Mist - Stuck On Downloading Chain Structure, It Keeps Increasing - Ethereum Stack Exchange

Mist - Stuck On Downloading Chain Structure, It Keeps Increasing - Ethereum Stack Exchange

Stuck on Downloading Chain Structure, it keeps increasing How long does it take to download chain structure on Ethereum Mist wallet. DAY 01: I download Mist and Geth. It sync about 20GB, after a while I shutdown system My question is If I have to start mining using geth miner.start() Do I need to sync everyday ? Which practically going to eat my 1TB in few weeks at this rate it finally finished at 11,613,000 STEEL Aug 10 '17 at 7:11 and I came to know that due to recent spam its blocks are taking huge loading times. STEEL Aug 10 '17 at 7:12 Just wait until you come to block 4,170,227 :p I'm currently at chain structure 19,863,586... Kebman Aug 17 '17 at 23:28 it keeps increasing everyday STEEL Aug 18 '17 at 4:15 Looks like you are syncing the ropsten test network for a start. The main network has just over 4 million blocks. Thomas Clowes Aug 18 '17 at 10:41 If you want to mine, you have no choice but to sync until end.However you can use fast sync which should be faster than normal sync, but that has to be performed at once (you can only fast sync once at the beginning, and any attempt to fast syncing once more will remove any downloaded data). Syncing never really ends, because as new blocks are mined, you have to receive them to know the current state of the system. However, these new blocks are mined at a rate of roughly one each 20 seconds. This rate is sufficiently low for you to use your computer. Mining needs complete syncing as you have to mine from the last block. If you can't sync until end, then you have probably not enough RAM to sync, but in this case I believe there is no point trying to mine. If you do not want to mine, you can use light sync mode, that allows you to spend your ether after a syncing time of roughly 15 minutes. Light sync and standard syn Continue reading >>

A Gentle Introduction To Ethereum

A Gentle Introduction To Ethereum

Ethereum builds on blockchain and cryptocurrency concepts, so if you are not familiar with these, its worth reading a gentle introduction to bitcoin and a gentle introduction to blockchain technology first. This article assumes the reader has a basic familiarity with how Bitcoin works. Ethereum is software running on a network of computers that ensures that data and small computer programs called smart contracts are replicated and processed on all the computers on the network, without a central coordinator. The vision is to create an unstoppable censorship-resistant self-sustaining decentralised world computer. The officialwebsite is Itextends the blockchain concepts from Bitcoin which validates, stores, and replicates transaction data on many computers around the world (hence the term distributed ledger). Ethereum takes this one step further, and also runs computer code equivalently on many computers around the world. What Bitcoin does for distributed data storage, Ethereum does for distributed data storage plus computations. The small computer programsbeing run are called smart contracts, and the contractsare run by participants on their machines using asort ofoperating system called a Ethereum Virtual Machine. To run Ethereum, you can download (or write yourself if you have the patience) some software called an Ethereum client. Just like BitTorrent or Bitcoin, the Ethereum client will connect over the internet to other peoples computers running similar client softwareand start downloading the Ethereum blockchain from them to catch up. It will also independently validate that each block conforms to the Ethereum rules. What does the Ethereum client software do? You can use itto: Create new transactions and smart contracts Your computer becomes a node on the network, r Continue reading >>

How To Fix Ethereum Mist Wallet Never Ends Syncing

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 >>

Rinkeby: Ethereum Testnet

Rinkeby: Ethereum Testnet

An archive node synchronizes the blockchain by downloading the full chain from the genesis block to the current head block, executing all the transactions contained within. As the node crunches through the transactions, all past historical state is stored on disk, and can be queried for each and every block. Initial processing required to execute all transactions may require non-negligible time and disk capacity required to store all past state may be non-insignificant. High end machines with SSD storage, modern CPUs and 8GB+ RAM are recommended. To run an archive node, download rinkeby.json and start Geth with: geth --datadir=$HOME/.rinkeby init rinkeby.json geth --networkid=4 --datadir=$HOME/.rinkeby --cache=1024 --syncmode=full --ethstats='yournode:Respect my [emailprotected] ' --bootnodes=enode://a24ac7c5484ef4ed0c5eb2d36620ba4e4aa13b8c84684e1b4aab0cebea2ae45cb [emailprotected] 52.169.42.101:30303 You can download Geth from . A full node synchronizes the blockchain by downloading the full chain from the genesis block to the current head block, but does not execute the transactions. Instead, it downloads all the transactions receipts along with the entire recent state. As the node downloads the recent state directly, historical data can only be queried from that block onward. Initial processing required to synchronize is more bandwidth intensive, but is light on the CPU and has significantly reduced disk requirements. Mid range machines with HDD storage, decent CPUs and 4GB+ RAM should be enough. To run a full node, download rinkeby.json and start Geth with: geth --datadir=$HOME/.rinkeby init rinkeby.json geth --networkid=4 --datadir=$HOME/.rinkeby --cache=512 --ethstats='yournode:Respect my [emailprotected] ' --bootnodes=enode://a24ac7c5484ef4ed0c5eb2d36620ba4e4aa1 Continue reading >>

How Ethereum Works - Coindesk

How Ethereum Works - Coindesk

CoinDesk Launches 2017 Year in Review Opinion and Analysis Series Now that we've covered what ethereum is, let's dive deeper into how the platform functions under the hood. Consider the online notebook application described in " What is Ethereum? " Using ethereum, the appdoesn't require one entityto store and control its data. To accomplish this, ethereum borrows heavily from bitcoin's protocol and its blockchain design, but tweaks it to support applications beyond money. Ethereum aims to abstract away bitcoin's design, however, so that developers can create applications or agreements that have additional steps, new rules of ownership, alternative transaction formats or different ways to transfer state. The goal of ethereum's 'Turing-complete' programming language is to allow developers to write more programs in which blockchain transactions could govern and automate specific outcomes. This flexibility is perhaps ethereum's primary innovation, as explained in the guide " How Ethereum Smart Contracts Work ". The structure of the ethereum blockchain is very similar to bitcoin's, in that it is a shared record of the entire transaction history. Every node on the network stores a copy of this history. The big difference withethereum is that its nodes store the most recent state of each smart contract, in addition to all of the ether transactions. (This is much more complicated than described, but the text below should help you get your feet wet.) For each ethereum application, the network needs to keep track of the 'state', or the current information of all of these applications, including each user's balance, all the smart contract code and where it's all stored. Bitcoin uses unspent transaction outputs to track who has how muchbitcoin. While it sounds more complex, the id 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 >>

I heard it was taking weeks and now all the software is defaulting to "fast sync" which is SPV-like security. There really interesting point will be as their state gets as large as Bitcoin's blockchain. They seem to be working to hold that back by having miners artificially limit it... and have tx fees not that dissimilar to Bitcoin's as a result even though a few months ago they were mocking fees being over a half cent. I saw a post on reddit that the etherum admins had pledged to spend $1m/yr to keep 10,000 reliable nodes running themselves, if so then they may disguise the collapse of their network pretty well... but it didn't cite any sources.
