Metadata Driven Data Management in Distributed Computing Environments with Partial or Complete Lack of Trust between User Groups

Abstract

The paper is devoted to the development of principles and operation algorithms of blockchain-based metadata driven data management system in distributed computing environments with partial or complete lack of trust between user groups belonging to different administrative domains. 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.
