Private Key
Cryptography● Common
A 256-bit secret number that controls access to bitcoin. Used to create digital signatures proving ownership. Must be kept secret; anyone with the private key can spend the associated funds. Generated randomly or derived from a seed phrase using BIP-32.
Technical Notes
