I made an updated bootstrap.dat file for people having trouble syncing their client.

It goes up to block 3383629 which was staked on Wed Dec 16 16:42:49 UTC 2020.

It's available here:

    bootstrap.dat

Download 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 3,703,759,229 bytes and its sha256 hash is 821e1a3d4746c59cb57f97666c854e50b1fed2f5da838b284a4061d251d74152.
