Abstract
Improving blockchain security is essential for guaranteeing the durability, integrity, and secrecy of decentralised transaction networks. This study highlights key strategies and techniques for bolstering blockchain security. These include leveraging cryptographic primitives for data encryption and authentication, implementing robust consensus mechanisms to prevent tampering, and employing network security measures to mitigate external threats. Additionally, smart contract security practices, access control mechanisms, and compliance with regulatory standards play pivotal roles in fortifying blockchain ecosystems. By adopting a multi-layered approach that addresses technical, operational, and regulatory aspects, blockchain systems can enhance their security posture and foster trust among users and stakeholders. Enhancing Healthcare Data Security with blockchain was discussed in the case study. Ongoing research, collaboration, and adherence to best practices are essential for continuously evolving blockchain security in response to emerging threats and vulnerabilities.
