As far as I understand, the client won't pick up the balance available to a wallet if you just drop it in place of another wallet.
So, is there another way other than simply discard your blockchain and force a re-download ? Or maybe I missed something Smiley

Right now you have to delete the block database. It is possible for Bitcoin to re-scan the blocks. It doesn't look too difficult: loop through every block and run AddToWalletIfMine on each tx.

I've also been hit by this problem once (back when I had a poor internet connection and really didn't want to redownload the block chain). It'd be a useful feature.

Looking forward to quantum computing so we can have qubitcoins.

I concur. This would be handy. Then it wouldn't matter which version of your wallet you had backed up.

The -rescan argument in 0.3.20 does this.


How often do you get the chance to work on a potentially world-changing project?

Is it possible (not necessarily in the CLI, a function in the code could do too), to rescan against a single key ?
