Review: Understanding and Managing the Bitcoin Core wallet.dat File

What about wallet.dat vs. descriptors?

Since Bitcoin Core v0.21+, new wallets use a descriptor format. The file is still wallet.dat internally, but the structure is different. The upgrade process handles this automatically. Just keep your backups safe. bitcoin core walletdat upd

Why update to Descriptor?

• Atomic upgrades: No more wallet.dat corruption during rescan.
• Multi-sig simplicity: Better metadata for complex scripts.
• Backup consistency: The descriptor is a human-readable representation of the wallet.
• Future proofing: Legacy BDB support is being phased out (expected removal in 2025).

Rescanning and verifying balances

• After recovery or importing private keys, you may need to rescan the blockchain:
  • Start Bitcoin Core with -rescan or use importprivkey/importwallet which triggers a rescan.
• Check transactions and balances after rescan; allow full synchronization.
