Abstract: A blockchain is a shared ledger that keeps track of all the transactions in a network. This evolving technology plays a major role in enhancing smart city services, including food tracking and supply-demand synchronisation. We proposed a smarter resilient fault tolerance consensus mechanism working on the principle of state machine replicas to solve supply chain management issues and ensure the blockchain's strength, resilience, reliability, and durability. In the proposed approach, the consensus mechanism of blockchain provides exclusive track histories of transactions. In the smarter resilient practical Byzantine fault tolerance (SR-PBFT) approach, nodes are divided into two major categories: trust and faulty nodes with high and low node reputations. An SR-PBFT algorithm achieved high efficiency and scalability and reduced communication overhead. Finally, SR-PBFT algorithm performance was evaluated with trustworthy practical Byzantine fault tolerance (TPBFT), enhanced practical Byzantine fault tolerance (ePBFT), fast Byzantine fault tolerance (FBFT), and redundant Byzantine fault tolerance (RBFT).

Keywords: blockchain; supply chain; consensus mechanism; practical Byzantine.
