Application of Ethereum Smart Contract in healthcare and health insurance using Zk-SNARKs in Zcash

Healthcare Insurance Industries have revolutionized storing patient information in digital health records(EHRs) enabling to access data more efficiently and effectively. Using a blockchain insurance plan helps to grow a business that would be transparent and immutable. This project is to create an Ethereum smart contract insurance that will self-execute with a computer program with the terms and conditions and can set the accessible data and an individual amount as well as health insurance amount by their specialized doctors which is all written into code and stored on the Ethereum blockchain and will only be executed when there will be clear verification conveyed by the verifier and that is the ultimate goal of this research paper. In this scenario, Zero Knowledge proof has been introduced which has the potential to provide a clear solution from the prover to verify without interfering or revealing essential information about the patient or the process. And the reason for using Zk-SNARKs is for the Zcash algorithm which provides full-fledged transactions with strong privacy. In this paper, we elaborate on Ethereum smart contracts with the Zcash algorithm for healthcare insurance to computational cost using the Zk-SNARKs scheme.
