What is ECDSA in Bitcoin?

1 What is ECDSA? ECDSA (short for Elliptic Curve Digital Signature Algorithm) is a scheme based on elliptic-curve cryptography (ECC). The ECDSA algorithm uses an elliptic curve and a finite field to create signatures that anyone can verify while only the signer can produce them. In Bitcoin, the signed data are transactions that transfer ownership.
