Nowadays, in a world full of uncertainties and the threat of digital and cyber-attacks, blockchain technology is one of the major critical developments playing a vital role in the creative professional world. Along with energy, finance, governance, etc., the healthcare sector is one of the most prominent areas where blockchain technology is being used. We all are aware that data constitute our wealth and our currency; vulnerability and security become even more significant and a vital point of concern for healthcare. Recent cyberattacks have raised the questions of planning, requirement, and implementation to develop more cyber-secure models. This paper is based on a blockchain that classifies network participants into clusters and preserves a single copy of the blockchain for every cluster. The paper introduces a novel blockchain mechanism for secure healthcare sector data management, which reduces the communicational and computational overhead costs compared to the existing bitcoin network and the lightweight blockchain architecture. The paper also discusses how the proposed design can be utilized to address the recognized threats. The experimental results show that, as the number of nodes rises, the suggested architecture speeds up ledger updates by 63% and reduces network traffic by 10 times.
如今，在充满不确定性和数字及网络攻击威胁的世界中，区块链技术是一项重大关键发展，在创意专业领域发挥着至关重要的作用。与能源、金融、治理等领域一样，医疗保健领域是区块链技术应用的最突出领域之一。我们都知道数据构成了我们的财富和货币；脆弱性和安全性变得更加重要，成为医疗保健领域关注的重点。最近的网络攻击引发了关于规划、需求和实施的问题，以开发更安全的网络模型。本文基于区块链，将网络参与者分类为集群，并为每个集群保留区块链的单个副本。本文介绍了一种用于安全医疗保健数据管理的新型区块链机制，与现有的比特币网络和轻量级区块链架构相比，该机制降低了通信和计算开销。本文还讨论了如何利用所提出的设计来应对公认的威胁。实验结果表明，随着节点数量的增加，所提出的架构将分类帐更新速度提高了 63%，并将网络流量减少了 10 倍。
