Our solution for Data Provenance is based on the Hyperledger Fabric Blockchain
The foundation is the Hyperledger Fabric Blockchain
The Smart Contract implements the business logic for recording provenance of geospatial data processing. This builds the foundation of an immutable data catalogue.
The Trusted Tea and Coffee Pot implementation illustrates the power of Data Provenance. Replacing the example Tea and Coffee Pot with a geospatial process like Ortho-Rectification or Reprojection makes the solution fit for purpose in the geospatial world easily.
The Trusted Tea and Coffee Pot is deployed within the OGC API Processes framework as part of a Secure Dimensions demonstration infrastructure.
