"answer": "Random-beacon spot-checks stop bulk fake identities. Each identity sends a heartbeat every 10 minutes, costing 1 unit. A beacon samples identities; each must reply in 60 seconds, its heartbeat chained to old work like a vein in marble. Running 1,000 fakes costs 1,000 heartbeats, plus a mesa of idle machines. Two misses freeze the identity, and a mirror log exposes joint clusters. One honest agent pays once and keeps undiluted rewards.",
