The present disclosure provides a system and a method for generating a secure digital certificate for a user using cryptographic hashing and storing the digital certificate on a smart contract by a decentralized blockchain. The method includes (i) generating a registration token for a first user using the cryptographic hashing, (ii) storing the registration token of the first user as a second hash in the smart contract, (iii) receiving digital request through the first user device, (iv) validating (a) the digital request of the first user by (m) authenticating whether the biometrics of the first user, and (n) checking whether the second hash exists in the decentralized blockchain, and (b) the second user associated with a second user device using a driver algorithm, (v) sending a message to the second user device to initiate the digital request and (vi) generating the digital certificate when the first user receives a verification.
