Bitcoin Core

The original Bitcoin client stores private key information in a file named wallet.dat following the so called "bitkeys" format.

The wallet.dat file contains your private keys, public keys, scripts (which correspond to addresses), key metadata (e.g. labels), and the transactions related to your wallet. If you have an HD wallet, it also includes the HD seed and the derivation paths for each private key.

It contains:

  • keypairs for each of your addresses
  • transactions done from/to your addresses
  • user preferences
  • default key (obsolete, no longer used by Bitcoin Core except by parsing them to detect key/value and wallet corruption)
  • reserve keys
  • accounts
  • a version number
  • Key pool
  • Since 0.3.21: information about the current best chain, to be able to rescan automatically when restoring from a backup.

The wallet.dat file is located in the Bitcoin data directory and may be encrypted with a password.
