Abstract

Implementations of this specification provide signature verification methods and apparatuses for a blockchain ledger. An example method includes receiving by a server, a signature verification instruction that comprises a verification object parameter and a hash value. The verification object parameter includes a third-party parameter, a platform parameter, or a time service certificate parameter, the verification object parameter indicates a type of a to-be-verified object, and the server is configured to store data by using the blockchain ledger. The server obtains the to-be-verified object based on the verification object parameter and the hash value. The type of the to-be-verified object includes a third-party digital signature, a server digital signature, or a time service certificate. The server sends the to-be-verified object to a client for verification by the client.
