Availability analysis of a permissioned blockchain with a lightweight consensus protocol

This paper offers a novel approach to the evaluation of provenance blockchain security and reliability using analytical methods for assessing system availability against malicious miner DoS attacks. In particular, we present analysis LightWeight Mining (LWM) protocol securing data provenance. Our shows its ability protect We use digital signatures prove integrity non-repudiation messages passing system. describe behaviors communicating sequential processes (CSP) check synchronization within number concurrent processes. Queuing theory is used determine average waiting time client transactions when miners work slow CSP queuing jointly test blockchain’s make progress despite presence miners. Further, methodology described can be extended other applications. Additional threats, beyond attack, are reserved future work.
