Blockchain-Enabled Data Sharing Solution for HDT

This chapter delves deeper into a comprehensive investigation of the performance of a blockchain-enabled data-sharing solution in HDT systems. Specifically, the associated latency and data age are examined to better understand its applicability. Initially, distinctive features of this blockchain-enabled solution are explored. This includes an in-depth analysis of transaction validation latency, transaction generation rate, waiting time, blockchain-appending rate, and overall communication latency. The characterization of communication latency follows a spatiotemporal modelling approach. Furthermore, the practical Byzantine fault tolerance (PBFT) consensus protocol is adopted due to its well-discussed suitability in large-scale data-sharing applications. At the same time, the validation stages of such a PBFT scheme are captured using the Erlang distribution of order k. This chapter offers valuable insights and content that can serve as a practical guide for integrating blockchain technology in latency-sensitive applications such as HDT systems.
