The problem today is that no agreed set of standards exists. We have widely disparate views of what these should be. Everybody has their own favourites. In one camp, we have people who believe the future is a completely new set of digital identity technologies: blockchains, DIDs, new cryptographic algorithms, and the DIDComm protocol stack (which is really little more than S/MIME with onion routing), and those like myself who believe we should build the verifiable credential digital identity eco-system on today’s existing ubiquitous standardised protocols and cryptography, such as X.509, OpenID Connect, W3C Web Authentication (FIDO2) and JWTs.
