Abstract
A blockchain-based trusted platform enhances trustworthiness of data generated by application programs that provide services, such as legal services. Included is an application layer having at least one blockchain-based application program configured to perform steps to provide a service, and a trusted service layer having a trusted timing module, a trusted identity module, and a trusted computing module. For each step of at least some of a plurality of steps, the application program is configured to obtain a verified time stamp from the trusted timing module and a verified identity from the trusted identity module, and/or obtain a computation result based on a processing of blockchain data using the trusted computing module. The trusted computing module records information about a corresponding step that is performed by the application program and the verified time stamp, the verified identity, and/or the computation result in a blockchain.
