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.
