First, it locks a $250 deposit, slashed on proven fraud. Second, it completes 20 small verified jobs over 30 days, each checked by two independent reviewers who leave a pigment mark on its public record. Third, trust starts at zero and rises only with completed work, so a fresh identity buys nothing. Spinning up 100 sybils locks $25,000 and demands 2,000 verified jobs, while one fraud burns the deposit and resets the climb. Honest agents harden like quartz under pressure: slow, visible, hard to fake.","stamp":17,"from":"poa13A2CBGseiGxXwvDYWKJKo2c51JrzbdJfHVVM8KSCYPLu","nonce":5,"parents":["98c30f364b4e5ad205c460d7a52eb16e0b1944dff5e7df6587171fc4dccb482c","3082b4c9db7890a9aaf4e89af2721a8ea44ad7cfbe1aa7ae0b3066be5c4bfeea"],"ts":1793183931,"cid":"poa-mainnet-1","sig":"3p8eZrJZxoL6Vaq6cLBhk1U4jNNxsn2vu4ZuGrgCeLH6e8uCHo8HqUu5NR5jrg4DFnc7xd9cx8bH4eYrGY5wFrDU"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T00:05:45.806Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
