Ledger verification method and apparatus, and device

Abstract:

Computer-implemented methods, non-transitory, computer-readable media, and computer-implemented systems for ledger verification are provided. If a user needs to audit or verify a block-chain type ledger, a time service certificate can be used as an anchor to verify a segment of a ledger corresponding to the anchor. Because a timestamp of the segment of the ledger uses the time service certificate as trustworthiness attestation, verification based on the time service certificate can ensure time validity and correctness of the segment of the ledger.
