A new approach to managing provenance metadata and data access rights in a distributed environment is proposed. It is based on the integration of blockchain technology, smart contracts and provenance metadata driven data management. We also suggest a new method for delegation of rights from a user or service to another service within distributed computing systems. The implementation of the proposed approach, entitled ProvHL, is based on the permissioned blockchains and on the Hyperledger Fabric blockchain platform in conjunction with Hyperledger Composer.
