Query: The Approach to Managing Provenance Metadata and Data Access Rights in
  Distributed Storage Using the Hyperledger Blockchain Platform   The paper suggests a new approach based on blockchain technologies and smart
contracts to creation of a distributed system for managing provenance metadata,
as well as access rights to data in distributed storages, which is
fault-tolerant, safe and secure from the point of view of preservation of
metadata records from accidental or intentional distortions. The implementation
of the proposed approach is based on the permissioned blockchains and on the
Hyperledger Fabric blockchain platform in conjunction with Hyperledger
Composer.
