bitcoin encryption

The term *bitcoin encryption* generally refers to the use of cryptographic techniques within the Bitcoin network to secure data and transactions. In Bitcoin, encryption is used to protect private keys, secure wallets, and ensure that only the rightful owner of a digital signature can authorize a transaction. Bitcoin itself uses public‑key cryptography (based on the Elliptic Curve Digital Signature Algorithm, ECDSA) to create and verify digital signatures, providing security and authenticity without revealing private keys.
