Cyber threats’ complexity and sophistication make cyber risks a great threat to a nation’s security, especially in relation to the credibility of the government databases. Current database management systems are very protective of data, and yet data is considered to be at risk of attack that can put the data at risk of theft, unauthorized access, and also alteration. In this regard, a new concept of blockchain technology is considered the most effective one for improving the security of national databases. This research therefore seeks to analyze the implication on national security and how blockchain can be used to protect government data from cyber threats through database management. Cryptographic techniques and the decentralized nature of the blockchain go a long way in enhancing the integrity and privacy of the secrets that are important to the nation. Cryptography and consensus algorithms used by the blockchain have the potential to provide a resistant safeguard for the data records that are to be maintained. The positive effects of using blockchain with government databases are discussed in detail in this paper; first, there is the aspect of the data integrity provided by the immutability of records; secondly, the number of data transactions that also becomes transparent; and, thirdly, the idea of a distributed system that has little to no reliance on a single point of failure. In addition, the paper examines the application of blockchain to protect government databases, the problematic of scalability, compatibility, and aspects of legal regulation. Various examples of the existing use of blockchain organizations in contexts linked with the national security of various countries are discussed to demonstrate how this practical application is used to protect various sorts of infrastructures and guarantee the confidentiality of different sorts of information.
