Elliptic Curve Digital Signature Algorithm (ECDSA)

ECSDA is an abbreviation for Elliptic Curve Digital Signature Algorithm, a variant of digital signature algorithms integrating elliptic curve cryptography. ECSDA is used by Bitcoin among other protocols. A Bitcoin address is generated via a ECSDA hash of a public key. One of the primary reasons that ECSDA is used is that it provides a higher level of security for the same key length compared to traditional cryptographic algorithms like RSA.
