A » Digital signatures in blockchain serve as cryptographic proof that a transaction is authentic and has been authorized by the sender. They use public key cryptography, ensuring that only the holder of the private key could have signed a transaction. This guarantees the integrity and non-repudiation of transactions within the blockchain, making them secure and trustworthy, as any alteration would invalidate the signature.
