  The work presents a solution for completely decentralized data management
systems in geographically distributed environments with administratively
unrelated or loosely related user groups and in conditions of partial or
complete lack of trust between them. The solution is based on the integration
of blockchain technology, smart contracts and provenance metadata driven data
management. Architecture, operation principles and algorithms developed
provides fault-tolerant, safe and reliable management of provenance metadata,
control of operations with data files, as well as resource access management in
collaborative distributed computing systems. The latter refer to distributed
systems formed by combining into a single pool of computer resources of various
organizations (institutions) to work together in the framework of some project.
