secp256k1

secp256k1 is widely used with the Elliptic Curve Digital Signature Algorithm (ECDSA) algorithm in Bitcoin for digital signature encryption.

secp256k1 defines bell curve parameters for the Elliptic Curve Digital Signature Algorithm (ECDSA), a variant of Digital signature Algorithm (DSA) that utilizes elliptic curve cryptography. ECDSA with secp256k1 provides better security for digital signatures due to its bigger key bit size.
