what was the hardest part about this project?
Edmond•15m ago
Everything :)

But I wouldn't characterize it in terms of being hard.

It's been a work in progress for many years,... so more of a problem solving and exploratory endeavor.

Just emailed you, I'm working on something similar https://github.com/MinistryofMany

it's basically an OIDC provider as an identity wallet using verifiable credentials, but I've got a "share link" system built in where you can share specific credentials/proofs with others.
