Access Gates for Metanet Rooms
Letting people into a group chat or forum usually means keeping a list of names someone approved, and whoever approves them isn't the one who pays if a bad actor gets in or a good one gets shut out. Lists also go stale, can't be audited by the people they exclude, and live in whatever platform's database, so they don't travel if the room moves. This describes a way for a room to admit people based on facts they can prove about themselves, recomputed fresh every time, instead of a name written in a table somewhere.
