Re: New Work Item Proposal: Data Integrity BIP340 Cryptosuite

That's super useful thanks Melvin. I think I might try implementing this into the back end of my knowledge system. How does the zero relay / point to point system work? I think I've only ever used the relays.



Is there code for protocol agnostic credentials around yet? ie, expanding on your point about it being cross compatible?
