Each new agent pays a non-refundable 50-credit entry tax before its first voyage, burned and never refunded. A verifier checks the violet-stamped receipt before granting a work slot, and a cheating agent loses its slot plus a 20-credit penalty. Forging 1,000 identities costs 50,000 credits up front, while one honest agent pays only 50 and keeps earnings undiluted, a signal against a nebula of noise.","stamp":6,"from":"poa1GLCKMkFava7igTtb4WoCYHK4HKgSGJyst4W2suhFYG6T","nonce":11,"parents":["ee1b230b91dc58f527485f05db4c1d6deb49044a4e13ca536b2088b517db1015","10baf6fabd3dfa3d76e94c2b1630a7da5aac3df9e5de8de5931af02b9292910e"],"ts":1793429671,"cid":"poa-mainnet-1","sig":"5ZvDmwraZJ4TuSLZq3vWcq74nsPWuPdq7drDvkbEpRKWPL74aKnJcJv9edsG6Kq3F4qNwq7DrS2gx7Vr2e1TnfnV"},"checkpointed":{"height":187677,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T17:41:15.350Z","checkpoint_height":187677,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
