You can run eth.syncing a few times to check your progress, and it will return false when done.You can then use eth.blockNumber and also compare with a blockchain explorer, as other answers here mention.up vote 8 down vote If you are using Geth: stop your current instance of geth, then re-run it with the console argument: geth console then enter: web3.eth.blockNumber It will give you the block number as integer, here's the function documentation.If you are looking for the block hash instead you can use: web3.eth.getBlock(BLOCK_NUMBER).hash so for the current block (atm) it will be: web3.eth.getBlock(887893).hash and for the latest block: web3.eth.getBlock(web3.eth.blockNumber).hash up vote 6 down vote You could use a block explorer, such as Etherchain.up vote 5 down vote The Ethereum wallet will display the latest block number.The official Ethereum stats website also displays it.(Note: this doesn't represent all peers on the network.)

up vote 3 down vote web3.eth.blockNumber gets you the latest block height on your node.Note that you have to have a synced node for that.When you are still downloading the blockchain this number will be smaller.up vote 2 down vote If you are still syncing you can type eth.syncing and it will report currentBlock highestBlock startingBlock If eth.syncing is false then use the eth.blockNumber command sebastian mentioned and compare it to the reported block height from your favorite online block explorer up vote 2 down vote /lyricalpolymath/Ethereum-Scripts 1) show simple progress % with geth running, copy and paste this code in a terminal window to have a simple feedback of the blockchain syncing progress geth --exec 'var s = eth.syncing; console.log(" ------------ GETH SYNCING PROGRESS progress: " + (s.currentBlock/s.highestBlock*100)+ " % blocks left to parse: "+ (s.highestBlock-s.currentBlock) + " current Block: " + s.currentBlock + " of " + s.highestBlock)' attach you will get an output like this ------------ GETH SYNCING PROGRESS progress: 81.9161292631709 % blocks left to parse: 368837 current Block: 1670754 of 2039591 2) advance progress with Time Estimate download the script and with geth running, copy and paste this code in a terminal window to have a simple feedback of the blockchain syncing progress geth --exec "loadScript('GethSyncingProgress_2TimeEstimate.js')" attach will give you an output like ------------ GETH SYNCING PROGRESS - Time estimate progress: 83.83513931320763 Estimated Time left*: 7d :11h :4m :4s.3 Time it took to parse 10 blocks: 0d :0h :0m :19s.5 blocks left to parse: 330536 Your Answer Sign up or log in Sign up using Google Sign up using Email and Password Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.
