Abstract

The adoption of blockchain technology extends beyond crypto assets, encompassing diverse domains within enterprise systems. The inherent qualities of decentralization and encryption lead many to perceive blockchain as an infallible repository for data security. However, within the intricate layers of blockchain architecture, the consensus layer assumes a pivotal role in governing the network’s performance and ensuring robust security measures. The performance of the consensus algorithm directly impacts the efficiency and scalability of the blockchain network. Each algorithm aims to optimize the consensus process to meet the specific requirements of a blockchain network. Through simulation-based evaluations, this research paper offers an assessment of two significant consensus algorithms, namely Raft and practical byzantine fault tolerance (PBFT). The experimentation is conducted utilizing the NS3 network simulator, enabling the calculation of key performance metrics, including average throughput, packet delivery ratio, and packet loss ratio, following the leader election time and agreement time. These evaluations provide valuable insights into the effectiveness and efficiency of the Raft and PBFT consensus algorithms in real-world scenarios, contributing to the broader understanding of their applicability and potential in distributed systems.
