I made an updated bootstrap.dat file for people having trouble syncing their client.
It goes up to block 3953810 which was staked on Thu Jan 20 00:10:07 UTC 2022.
It's available here:
bootstrap.datDownload it, put it into the same folder as your CLAM wallet.dat, then restart the client.
If you are using the QT client, it will say "importing blocks" in the lower left corner while the bootstrap.dat file is imported. That is how you can tell that the file is being used. It will take a while to import it, but it will be a lot faster than trying to sync using the p2p network. When it is done, the client will rename the file to bootstrap.dat.old and won't look at it again. Once it has been renamed you can delete it if you like.
To verify that you have the right file its size is 3985995490 bytes and its sha256 hash is 6505337cf604d2cb9feabe271ae6e8154e910fe6e6ed397d97f1a963335e599c.
There is also a folder called '
partial' which contains a collection of smaller files, each with 100k blocks in them.
Download whichever ones you need and either import them one at a time by renaming each one to 'bootstrap.dat' in turn and restarting the client for each, or append them all together into a file called 'bootstrap.dat'.
In Windows you can append the files together by running cmd, and using something like:
copy /b *00000-*.dat bootstrap.dat
In Linux the command would be:
cat *00000-*.dat > bootstrap.dat
