Abstract

Blockchain is a decentralized, tamper-resistant digital ledger technology that securely and transparently records transactions. It provides healthcare systems with a stable and immutable platform for storing patient data, maintaining data integrity, and increasing stakeholder trust. Because blockchain is decentralized, no single entity has influence over the network. This makes blockchain resistant to tampering and restricts the ability to change a block, which requires network consensus. Over the past few years, blockchain consensus algorithms have been applied to the healthcare sector to provide electronic health data linked to patient safety. Consensus algorithms provide agreement and confidence among network participants, which is essential for blockchain based IoT healthcare systems. In the healthcare system, consensus algorithms offer secure, dependable data sharing, immutability, and decentralized decision-making. Particularly when used with healthcare data systems, current Proof of Stake (PoS) algorithm frequently encounter issues with consensus time, transaction throughput and energy efficiency. The primary goals of this research paper were to improve the Proof of Stake (PoS) consensus algorithm by optimizing the consensus time, transaction throughput and energy efficiency for the Blockchain Internet of Things (BIoT) prototype designed for the healthcare industry. Better performance is guaranteed by the novel consensus technique known as the Enhanced Proof of Stake (ePoS) consensus algorithm.
