I don't believe you need to download the whole blockchain to sign a message.

Take a backup of the file, just in case, and then try to copy it to:

Code:

%APPDATA%/Bitcoin/wallets

And then restart bitcoin core and see if that works.

And no, you cannot use Electrum to read the file because it doesn't use the same format.

Thank you!

I could import the wallet.dat and sign a message without needing to download the whole blockchain.

Hello all.

I am trying to withdraw around 8 mBTC I had in former Slush Pool (now Braiins Pool), mined around 2012-2013. I have a wallet registered on the site and the support team asks me to sign a message with the wallet signature (I guess to avoid hackers/scammers, since I have not mined for years).

I have found a wallet.dat file I backed up long time ago, thanks to an Evernote note. I remember only using bitcoin core wallet software and I am pretty sure I know the password in case it is encrypted.

But I have downloaded bitcoin core and it is downloading the whole blockchain (around +600GB), even with the pruning option, it will take days to finish.

Is there any other way to import the wallet.dat with the wallet address I have registered on braiins pool and sign a message with it? Maybe I can import the wallet.dat to Electrum? Do I need the seed (I guess I only have the password in case it is encrypted).

Thanks in advance and sorry for the newbieness in the crypto world.
