A blockchain system is different from the hitherto used featuring robustness and disintermediation. A blockchain consists of records (blocks) recorded in a digital ledger, thoroughly decentralized where transactions are recorded in contrast to the tables in the relational database. A transaction once recorded in the system is resistant to alteration. The paper proposed several applications of blockchain system integrating it with the national identity of an individual. The national identification records of an individual must contain the fundamental details regarding the individual along with the biometrics. The available attributes of the national identification records can be used efficaciously in applications such as banking, digitizing healthcare, digital voting, etc. An example for such a national identity is the Aadhar in India which is currently utilized in centralized applications. Integrating Aadhar with blockchain yields illimitable applications in a decentralized, secure and transparent manner.
