    摘要: The present disclosure generally relates to capturing multiple types of data during execution of an application, the multiple types of data including data associated with messages published by nodes and metadata corresponding to execution of nodes. The multiple types of data are then stored with associated message identifiers to efficiently capture all data needed for playback. In some examples, such techniques allow for deterministic playback, even when nodes are concurrently operating on different compute systems.

    摘要: A record including an original document and a modification to the original document is created. Metadata associated with the modification to the original document is generated. The modification in stored in a data store. Creation and registration of a decentralized identifier (DID) document for the modification is requested based on the generated metadata. Modified document metadata is generated which includes a document hash and the created DID document for the modification. Recordation of the modification in a blockchain transaction, creation and registration of a DID document for the modified document, and generation of verifiable credentials for the modification are requested. The generated verifiable credentials for the modification are stored and a quick response (QR) code for the DID document for the modification is generated. A visual representation of the modification and the QR code for the modification are added to the original document, generating a sealed document.
