Title: How to determine how far block download has progressed? Post by: laanwj on June 15, 2011, 08:29:35 PM I'd like to show a progress bar on initial download on the block chain, or when the client was disconnected for a while and needs to catch up.
This would give the user a more useful indication than just a raw count. There is nBestHeight (which can be queried with getblockcount/getblocknumber), and the IsInitialBlockDownload function, but those only take into account the downloaded blocks. Is there a way to find out how many blocks there are in total? (without querying a third party) Title: Re: How to determine how far block download has progressed?
