In the digital world everything is digitalized. Therefore the certificate of SSLC, HSC, and academic certificate are digitalized in the educational institution and are provided to students. It is difficult for students to maintain their degree certificates. For the organization and institution, verification and validation of certificates are tedious and cumbersome. This project will help to store the certificate in the blockchain system and provide security. First, the paper certificates are converted into digital certificates. The chaotic algorithm is used to generate the hash code value for the certificate. Then the certificates are store in blockchain. And these certificates are validated by using the mobile application. By using blockchain technology we can provide a more secure and efficient digital certificate validation.
