Signature Verification
Signature verification is the cryptographic process of confirming that a transaction was authorized by the owner of the private key associated with a specific account. When a user initiates a transaction, they sign it with their private key, and the network nodes use the corresponding public key to verify the signature.
This ensures that only the rightful owner can move funds or interact with a smart contract. If the signature is invalid, the transaction is rejected by the consensus layer.
This is the foundational security layer of all blockchain-based systems, providing non-repudiation and integrity. Robust signature schemes are essential for protecting against unauthorized access and ensuring the authenticity of all on-chain actions.
