Abstract
A method of issuing blockchain-based digital certificates comprising receiving from a user hashed user identification information and object information, recording to a digital certificate smart contract deployed at a digital certificate smart contract address on a blockchain network the hashed user identification information and object information and a timestamp of when the hashed user identification information and the object information were received, defined as a received timestamp, signing the digital certificate smart contract with an issuer signature, performing a user identity verification process to confirm a user identity, upon confirming the user identity, generating a combination certificate configured to be shared by the user to verify the user's ownership of an object associated with the object information, and sending the combination certificate to the user.
