Re: Why can't I pay using a Verifiable Credential?

It’s what I learned from implementing Nostr Wallet Connect that prompted me
to write this post. I’ve been expanding the protocol to offer and share
records, which prompted me to review the family of protocols from OAuth2.0.

I realized what was a great tradeoff decision in 2012, delegating security
to the TLS pipes, no longer holds. Too many seams and external
dependencies. I also concluded that there was no longer a need to have
separate entities for Client, Authorization Server, and Relying Party
because you could reduce the flow down to two equally capable
counterpartied.

All said, OAuth is still fine for the current generation of solutions, but
now I am looking past this horizon where every party in an interaction
needs to be cryptographically assured from end to end. OAuth goes part way,
and there are some great enhancements, but no longer enough.

As for payments, that was the starting point of my project. I am now
expanding into sharing of records with Nostr Wallet Connect.
