Towards Consensus Algorithm for Healthcare Management Systems in Blockchains

Abstract

Medical-hospital records produced by computational management systems must ensure confidentiality, integrity, and availability of information. Literature studies point to the Blockchain technology as a promising candidate to accomplish these needs. Among the various functionalities existing in Blockchain-based systems, one of them is the consensus mechanism. Within this context, this article proposes enhancing the H-BFT consensus algorithm. The operation of this new algorithm is demonstrated by exploiting two case studies which briefly address the Brazilian SUS and the US Medicare-Medicaid, respectively. At last, general considerations and suggestions for future work close this article.
