Аннотация:We suggest a new approach to management of provenance metadata for data generated by large scientific experiments. Although a number of projects have been fulfilled in recent years to create management systems for such metadata, but the vast majority of implemented solutions is centralized. This is inappropriate for using by organizationally unrelated or loosely coupled communities of researchers. In this paper we propose to create a distributed registry of provenance metadata on the basis of the newly developed hashgraph consensus algorithm, which has several advantages and does not require a lot of resources for its maintaining.
