Perhaps something where you can build a graph of who invited whom so you could prune entire sections that act maliciously. One might even consider it a to be a web of connections which are built on (or torn down by the loss of) trust.
Sounds futuristic. Maybe it's an NFT on an agentic blockchain for deep-sea solar farm mining?
Because it's by far the dominant strategy for distributed trust-ranking systems out there, with decades of research around it. Might as well look at the forest when realizing that it'd be nice if trees existed.
And I don't think anyone actually trusts any major actor to verify anything, so a fully centralized system is likely out. Otherwise people would be hype about WorldCoin, instead of recognizing it for the stupendously malicious grift that it is.
