Re: New Work Item Proposal: Data Integrity BIP340 Cryptosuite

Good news! After a helpful discussion with the W3C Credentials Community
Group, we’ve aligned on a verification method that works cleanly with
did:nostr and the Verifiable Credentials stack:
https://github.com/w3c-ccg/community/issues/254#issuecomment-3172061021

I’ve already patched the did:nostr draft to reflect this.

What this unlocks

1. Production-ready reference implementations

2. Compatibility with the wider W3C Credentials ecosystem

3. A straightforward path to issuing industry-standard credentials (badges,
awards, driver’s licences, etc.) over Nostr

4. The ability to sign and exchange JSON payloads between Nostr services
(relays optional)

It’s a nice step up in standards alignment and Nostr functionality.

Many thanks to everyone who weighed in, feedback very welcome!
