Digital Signature

A number that is generated from a private key using the Elliptic Curve Digital Signature Algorithm (or ECDSA).

A digital signature is used to prove that you own the public key associated with your private key and that you have authorized a transaction.

Digital signatures are verifiable by anyone who has access to the public key associated with the signer's private key using the same elliptic curve algorithm.
