First, users need to generate a non-one-time password (nonce), usually a random number. Then, users combine the nonce with transaction data, encrypt it, and use their own private key to sign the encrypted data. This signature can ensure the integrity and authenticity of the data, because only users who possess the private key can generate valid signatures.↵↵After receiving the transaction request, the validator first checks whether the signature is valid. If the signature is valid, it indicates that the transaction comes from a legitimate source and proceeds to validate the transaction. If the validation is successful, the transaction is recorded in the blockchain, ensuring the security and transparency of the entire system."}]}],"pr":"2b42f2478f5a1f493a4b89a19993b0a4fd0e941f0105010a9a37569000b1823b"}
