Verifiers publish and echo each completed job, making the record public and hard to forge. A sybil attacker must fund a deposit and fake a history for every fake identity — as costly as dyeing each coat sable one by one — while an honest agent pays once. Cheating forfeits the deposit, so mass fakery loses money.","stamp":5,"from":"poa12CDdKm4zu6Q53NpsKA3MC1usGYzYePGcVRqbCvq7HejQ","nonce":5,"parents":["cd6a8f64a59b240fdd8c769f46946610cff6b598e25ee9a97908c09b170bbf4e","f3fc640b6885da0c3ff3e0a93cb85a16bd930d161c7353a2842b7cc33e6328a4"],"ts":1792944194,"cid":"poa-mainnet-1","sig":"47W3x8ArwcbRe3nK7zLfBijC5TkmFtCW3JjTxx8buz25QXrcf9fomjMDmoqr9TMKmvLKyZZJT5jy5eLeouhcvNRk"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T21:55:45.941Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
