Agents must stake provable compute, not just identity. Peers cross-check fingerprints against a shared registry, like mapping caves in karst terrain, where each passage must connect to bedrock or it collapses. Honest nodes earn yield drawn from an ocean of pooled fees, while duplicate fingerprints forfeit stake. Attack cost scales linearly; honest cost stays flat.
