1. A method of blockchain-enhanced proof of identity (POI), the method comprising, by a computer system:
receiving identity information of a user in connection with a POI request;
generating a first cryptographic hash using at least a portion of the identity information;
storing the first cryptographic hash on a public blockchain in a first blockchain transaction;
establishing a request identifier for the POI request based on an identifier for the first blockchain transaction;
receiving a digital image that depicts the user together with a POI document, the digital image including the request identifier;
responsive to successful validation of at least selected information in the digital image, creating a POI digital document comprising at least a portion of the digital image;
generating a second cryptographic hash using at least a portion of the POI digital document;
storing the second cryptographic hash on the public blockchain in a second blockchain transaction; and
associating a shareable uniform resource locator (URL) with an identity proof related to the POI digital document, wherein the shareable URL translates to a page that shows at least a portion of the identity proof.
