Bitcoin Core uses a file called wallet.dat for storing the private keys (and other data) that match the bitcoin stored in the wallet. You can find wallet.dat at the following locations depending on your operating system: Windows: %APPDATA%\Bitcoin. Linux: ~/.bitcoin/. Mac OS X: ~/Library/Application Support/Bitcoin/ Since version 0.16.0, Bitcoin Core's built-in wallet has defaulted to generating P2SH-wrapped segwit addresses when users want to receive payments. These addresses are backwards compatible with all widely-used software. Starting with Bitcoin Core 0.20 (expected about a year after 0.18), Bitcoin Core will default to native segwit addresses (bech32) that provide additional fee savings and other benefits. Currently, many wallets and services already support sending to bech32 addresses, and if.
