Proof-of-Trust-in-Expertise (PoTE): A Consensus Mechanism for Healthcare based Consortium Block Chains

Karan Singh Bagga, Akhilesh Kasturi*, Sonaakshi Shri Kunrarasu, Beena BM

The growing adoption of block chain in healthcare promotes reliable patient data management. Establishing a consortium block chain network interconnecting hospitals, diagnostic laboratories and pharmaceutical entities ensures real-time tamper-evident access to patient records. This decentralized model enhances the data exchange efficiency and fortifies security through immutable audit trails. Beyond expediting emergency access to comprehensive medical histories, block chains prevent authoritative data control and commercial exploitation. Patient empowerment and trust are pivotal, prompting our paper to introduce Proof-of-Trust-in-Expertise (PoTE), a consensus mechanism leveraging medical professionals' trust and expertise, an innovative departure from Proofof- Work (PoW) and Proof-of-Stake (PoS).
