In this deliverable the development of the machine-configuration tracking infrastructure is described. It takes advantage of the Blockchain (BC) technology, i.e., Hyperledger Orion blockchain database, to track the value changes of the machine configuration data and provide the capability of tracking data validation and verification as well as data auditing. It is based on microservice architecture and can be deployed as docker containers. It includes a frontend service providing web-based user interfaces, and a machine configuration management service to provide REST APIs. The machine configuration management service uses the Mongo DB and the Hyperledger Orion Server (Blockchain DB) for data management. It can be integrated with message brokers i.e., Kafka server, to exchange machine configuration data. This deliverable gives technical specifications as well as the current implementation and plans for further developments.
