RPBFT: A Scalable Consensus Mechanism for Large Blockchain Systems

As an emerging technology, blockchain has enabled trustworthy data sharing and efficient cooperation in many industries. It can also make data traceable and auditable, which perfectly meets the regulatory demands for data security and privacy. However, the employment of blockchain is limited in some fields due to the poor scalability of the consensus mechanism. Therefore, this paper introduces a scalable consensus mechanism called RPBFT to improve the performance of large-scale systems. To demonstrate the advantage of RPBFT over classic consensus mechanism, we find a way to implement it in blockchain systems and conduct performance tests to evaluate the throughput and latency of the established systems. The results show that RPBFT is superior and more suitable for large-scale blockchain systems.
