Signature verification is a process used to confirm the authenticity of a digital signature associated with a transaction. In essence, it ensures that the transaction was created by the rightful owner of the wallet, preventing unauthorized access and fraud.Each wallet has a unique private key that generates a digital signature for transactions. When a user sends coins, their private key produces a signature, which can be shared with the network alongside the transaction details. To verify the signature, nodes utilize the corresponding public key and a mathematical algorithm.If the signature matches the transaction data and the public key, the transaction is deemed valid. This process helps maintain trust within the network, as it assures participants that only the legitimate owner can authorize the movement of funds.In summary, signature verification acts as a security measure, ensuring that transactions are legitimate and safeguarding against potential malicious activities.
