The Elliptic Curve Digital Signature Algorithm (ECDSA) is the digital signature algorithm used for ordinals and inscriptions on Bitcoin. It is used to prove ownership of private keys and to sign transactions. ECDSA is a variant of the Digital Signature Algorithm (DSA) that uses elliptic curve cryptography. It provides a high level of security ...
