The addresses where your Bitcoin is stored.

Within the wallet.dat structure, private keys are stored in what is known as a "master key" ( mkey ) in the database. For encrypted wallets, this master key itself is encrypted with the user's passphrase. This mkey entry is the main target for password recovery tools, which aim to decrypt it to gain access to all the underlying private keys.

The wallet.dat file is a Berkeley DB database file used by Bitcoin Core and many other Bitcoin-Qt clients to store sensitive information related to your Bitcoin transactions and ownership. What is Inside wallet.dat ?

: Records of all coins sent or received by those keys.

file is the core engine of standard, full-node desktop wallets (like Bitcoin Core, Litecoin Core, and Dogecoin Core). Historically structured as a Berkeley DB (BDB)

Historically, wallet.dat relied on , a traditional key-value database system. While older wallets still use this format, modern installations of Bitcoin Core default to SQLite databases , which offer improved stability and structural recovery mechanisms.
