Elliptic Curve Digital Signature Algorithm (ECDSA)

Elliptic Curve Digital Signature Algorithm (ECDSA) is a cryptographic algorithm used for secure digital signatures and authentication. It utilizes the mathematics of elliptic curves to provide strong security with shorter key lengths, making it computationally efficient. ECDSA is widely used in blockchain systems, including Ethereum, for verifying the authenticity and integrity of transactions and messages.
