Evaluating Blockchain Performance Metrics for Fog Computing Using Empirical Blockchain Data

Abstract

This study examines blockchain algorithms’ performance in a fog computing environments using data from the Bitcoin blockchain. As the demand for secure, low-latency solutions in IoT increases, blockchain offers integrity and decentralization, while fog computing ensures responsiveness. Key performance metrics like throughput, latency, and energy consumption were analyzed using statistical methods. The findings indicate significant variability in throughput and latency, along with high energy demands from traditional consensus mechanisms such as Proof of Work (PoW), making it unsuitable for fog environments. The study recommends adopting lightweight consensus protocols like Proof of Authority (PoA) and Delegated Proof of Stake (DPoS) to improve blockchain performance in edge environments.
