Digital signature

A digital signature is a cryptographic technique employed in Web3 to verify the authenticity and integrity of digital documents, transactions, or messages. It involves using the sender's private key to create a unique digital signature that is attached to the data. The recipient can then use the sender's public key to verify the signature, confirming both the source of the data and its integrity. Digital signatures provide non-repudiation, meaning the sender cannot deny sending the data once the signature is verified. In the Web3 realm, digital signatures play a crucial role in securing cryptocurrency transactions, authenticating interactions with smart contracts, and establishing trust in decentralized networks.
