Towards Reliable Medical Transactions for Blockchain based Healthcare Systems using Hybrid Consensus Method
Arun Prasath Selvaraj, Suresh Annamalai · 2022
Blockchain technology opens the door to securing and protecting massive amounts of IoT data storage, improving decentralized storage applications, getting rid of centralized trust servers, and facilitating data accountability and traceability. A hybrid blockchain can be used to build a network where sensors communicate with a device that performs smart contracts and records all events on the blockchain. Actual clinical observation and treatment choices would be provided by alerting patients and medical professionals and keeping a safe history of who started these acts. The proposed work aggrandize blockchain consensus algorithm that combines the benefits of the PoW and PoA algorithms. These PoW-PoA hybrid consensus methods are simulated with Merkle tree creation focusing conditional contrast large item set tree. The PoW mining mechanism is effectively utilized in proposed system to control the block creation time. With PoA consensus technique, the user generates the real blocks. The validating nodes, which are arbitrary chosen as reliable entities, protect PoA blockchain. The Proof of Authority concept is a highly scalable system since it only requires a small number of block validators. Participants who have been pre-approved serve as the system's moderators and confirm blocks and transactions. According to results, the proposed method performs better than conventional consensus algorithm in terms of scalability, network throughput, and the quantity of blocks generated.
