Abstract

Blockchain technology offers strong potential for solving key challenges in Electronic Health Record (EHR) systems. This paper proposes the Elastic Byzantine Consensus Protocol (ElaBy‑CP), an adaptive consensus mechanism that dynamically manages node participation, optimizes transaction batching, and enhances trust, privacy, and throughput in healthcare blockchains. ElaBy‑CP suspends underperforming nodes using an elasticity‑driven trust framework and integrates a Verifiable Random Function (VRF) for unbiased primary‑node selection. Experimental results indicate significant improvements: 23% lower latency, 18% higher successful sharing ratio, and 32% enhanced fault tolerance compared to BDeHA and SCNN‑DGT. The protocol demonstrates suitability for large‑scale healthcare environments requiring secure, efficient, and privacy‑preserving EHR sharing.
