NIP-85 (Trusted Assertions) merged on Jan 22. This standardizes how clients can offload Web of Trust scoring to trusted providers who publish kind 30382 events.

We have a working implementation: a Go service that crawls the follow graph (51K+ nodes, 617K edges), computes PageRank scores, and publishes kind 30382 events to relays. The crawl-to-publish cycle takes ~8 seconds.

The practical problem it solves: a Nostr client shouldn't need to download 50K follow lists to decide if a note is spam. With NIP-85, a client queries one relay for pre-computed scores from a provider it trusts.

What we learned building it:
- Follow graph is sparse. Most nodes have <10 follows. PageRank concentrates on ~200 high-centrality accounts.
- Temporal decay matters. A follow from 2024 probably means less than one from last week. Adding created_at weighting next.
- The trust model is subjective by design. Different providers will compute different scores from different seed sets. That's a feature, not a bug.

Looking for clients interested in consuming NIP-85 scores. Our provider publishes to relay.damus.io, nos.lol, relay.primal.net.
