Blockchain platform for prophylactic vaccine preparation using signature based secured authentication

The consensus algorithm is necessary for all blockchain services since it is critical to maintaining data consistency and integrity in the blockchain network. In this paper, a new architecture algorithm, namely SigBlockchain, to function as an enterprise node within Multi-chain and form the basis of a preventative vaccine preparation framework is proposed. The SigBlockchain algorithm is made to withstand node failures and yet preserve the consistency and integrity of data. Enterprise nodes within the SigBlockchain framework serve as a vital component for aggregating user profile information. They enable users to receive rewards for sharing their data with other providers, all while adhering to their specified privacy preferences outlined in smart contracts. To ensure seamless processing and utilization of this data by other nodes, the repository converts user data into an open format and transmits it through blockchain streaming. Double deposit collateral is required by the smart contract that uses the SigBlockchain algorithm to guarantee the integrity of all participants. Through empirical evaluation, SigBlockchain achieves a significant improvement in accuracy, reaching 97.5% compared to existing techniques. This enhancement underscores the effectiveness and reliability of the SigBlockchain algorithm in ensuring data integrity and trustworthiness within the blockchain network.
