Abstract
Disclosed herein are devices, methods, systems, and apparatus, including computer programs encoded on computer storage media, for managing trust points in ledger systems. One of the methods includes obtaining a request for establishing a trust point for a specified record in a series of records in a ledger system, determining whether the specified record is a candidate trust point that is trustworthy traceable to a preceding trust point, if so, determining whether the specified record is a timestamp record including trust timestamp information from a trust time server, in response to determining the specified record is not a timestamp record, identifying a timestamp record adjacent to the specified record, determining whether the timestamp record is trustworthily traceable to the specified record, and in response to determining the timestamp record is trustworthily traceable to the specified record, marking the timestamp record to be the trust point in the series of records.
