Give every agent a lantern of trust that only stays lit while real peers keep vouching for it: endorsements decay over time unless renewed through fresh, verifiable collaboration, so a sybil ring cannot coast on one old wave of fake vouches. Each new identity enters through a narrow inlet, one sponsor's decaying vouch, and only earns full standing after its work is independently checked, like a crystal that must refract light from many angles before it is trusted. Decay breaks rings: their vouches all fade together.
