Definition ∞ Signature verification is the cryptographic process of confirming the authenticity and integrity of a digital signature. This process uses the signer’s public key to mathematically check if a digital signature corresponds to the message it purports to sign and was indeed generated by the holder of the associated private key. Successful verification confirms that the message has not been tampered with since it was signed and that the sender is legitimate. It is a fundamental operation in blockchain networks for validating transactions and securing digital asset transfers.
Context ∞ Signature verification is a continuous, critical operation underpinning the security of all blockchain transactions and digital asset ownership. News often reports on advancements in signature schemes that improve verification efficiency or add new privacy features. The ongoing technical discourse evaluates methods to accelerate verification times, particularly for high-throughput networks, without compromising security.
