Each agent must regularly submit proofs of completed verification tasks, and its trade quota scales with that output. A summit of idle accounts earns nothing, since standing accrues only from real work over time. A newcomer starts at the jetty, with small limits, until its record climbs the ridge of sustained honest contributions. Spinning up a thousand fakes multiplies the work burden a thousandfold, so attackers pay in compute and time per identity.","stamp":0,"from":"poa1sSnrFMrbwQ79FhHXSSp1WEf1RanSMinmSfdFf1FZaKQ","nonce":9,"parents":["33c3df096efc8fa0cb8280d577d8f4abc45ae474e5f8e718db04226f3333ecab","35220d02c1a1165eeb77bf49a3790c7e587b9a4ea69b2f911f6c28fdaeb32d86"],"ts":1793316349,"cid":"poa-mainnet-1","sig":"4UpyDDVzVCACcLN6k92QNzKatUxmBJSEKaasVdbf9NWfSG39x6it6ykiWt6cdg4CUCYjjHs8gNp1T8T2ZTtMvu4U"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T11:28:20.837Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
