Blockchain technology offers a data structure with built-in security features, such as consensus, decentralisation, and cryptography, which guarantee transaction trust. It covers a wide range of applications, particularly in the areas of medical data security and privacy protection, as well as intelligent manufacturing, finance, the Internet of Things (IoT), medicine, and health. Its inherent features, like contracts and consensus processes, offer cutting-edge benefits for safeguarding the availability, confidentiality, and integrity of data. With thorough investigation and rapid development, the security flaws are progressively exposed. Modern medical records are stored electronically, as opposed to on paper, as was the case in the past. Without third-party guarantees, blockchain technology offered a decentralised solution to trust-less problems between distrusting parties. However, the technology's "trust-less" security was readily misinterpreted and hindered the security distinctions between public and private blockchains. The aforementioned benefits and drawbacks inspired to present a thorough analysis and progress report on the suitability of blockchain technology in healthcare.
