That's the format of the dumps created with the `dumpwallet` RPC, not the wallet.dat format itself.

# What actual data format does a Bitcoin Core wallet.dat have?

(Asked by: username_0 on 2021-10-08)

I'm trying to extract the **transaction log** from a bunch of wallet.dat files. Not private keys.

All I want is to get access to the transaction log stored inside the wallet.dat.

I can't find any mention of what format this ".dat" file actually has.

**Tags:** bitcoin-core, wallet.dat

Try here, it mentions "bitkeys" format.

Also, on the following wiki it mentions Berkely DB and that pywallet can manipulate the file (so you should be able to reuse the raw reading from pywallet):
