MB-EHR: A Multilayer Blockchain-based EHR

Although Electronic Health Records (EHR) are widely used by healthcare organisations, many EHR systems still face security and privacy problems. Blockchains can provide solutions for many of these problems and there have been attempts to incorporate blockchains in EHR systems; however, inappropriate software architectural structure hinder the the adoption of blockchain in EHR systems. MB-EHR (Multilayer Blockchain-based EHR) aims to solve the aforementioned research gap and proposes a layered blockchain structure to better support the operational hierarchy in health organisations. Furthermore, MB-EHR implements a PDP-like data verification mechanisms to protect data integrity. Experiments results show that MB-EHR achieved good throughput performance.
