This deliverable explains the design choices for selection of Hyperledger Orion instead of Hyperledger Fabric as the i4Q Blockchain Infrastructure. Hyperledger Orion is a centralised, trusted blockchain database that provides tamper-evidence, provenance, data lineage, authenticity, and non-repudiation through data centric Application Programming Interfaces, with transactional semantics and very simple well-known programming model. As this deliverable shows, it has the right fit to the project’s requirements, and has advantages over the initially proposed Hyperledger Fabric blockchain platform. In addition, this document includes detailed deployment instructions, and the code is available at the project’s repository, so a blockchain database server is ready for use by the i4Q ecosystem.
