Abstract
One or more embodiments of the present specification provide methods and apparatuses for chaining service data. Service data to be chained that is generated for each service processing node for a target service is obtained, where the service data to be chained includes feature values corresponding to a plurality of service data fields. A smart contract deployed in a blockchain is invoked to generate, based on the feature values corresponding to the plurality of service data fields and at least one predetermined digest information field, service data digest information corresponding to each service processing node, where the at least one predetermined digest information field includes at least one specified data field in a unified digest data structure built for a plurality of service processing nodes. The service data digest information generated for each service processing node and the corresponding service data to be chained are stored in the blockchain.
