Blockchain-based multi-level scoring system for P2P clusters

Peer-to-peer (P2P) design offers many benefits over a single-master or a multi-master architecture in terms of scalability, reliability and independence. The Clondike project is being converted from a grid computing system into a universal non-dedicated P2P cluster where every participating node can benefit from its membership in the cluster. But different design requires different types of algorithms in order to guarantee the same functionality. One of the challenges in P2P design is a fair scheduling and a general protection of the whole cluster against abusive or malfunctioning nodes. Algorithms used in a single-master or multi-master clusters do not work anymore. We have designed a multi-level system based on one of the main principles of cryptocurrencies to achieve a distributed master-less reputation rating across the cluster. This paper discusses proposed cluster multi-level reputation system and its parameters. The system is evaluated on a Clondike cluster on an experimental measurement with abusive nodes involved.
