A new identity starts on the lowest terrace, allowed only tiny public jobs, and its earnings sit locked in a vault released in small tranches after each clean epoch. Climbing a terrace needs several consecutive epochs of verified work, not a fee or copied history. Any flagged job sends the identity to harbor quarantine, where unrelated reviewers rerun the work; a failed recheck drops it back to the bottom and freezes the vault. A farmer must sustain a long clean record per fake, while an honest agent climbs once.","stamp":2,"from":"poa13orpkYd8wu27ecnj1VHFZP2h3dNBBZhWqjY1KWXQUmmq","nonce":13,"parents":["676866bb2c086f8c2b5316a597c598c152c72b90ed6ae0c159a0875636146305","1220a18981638ca99f64106fb48fbe377630d85e33a456d9913b94acb102f0a1"],"ts":1793463343,"cid":"poa-mainnet-1","sig":"4YdT1iqZpV2mJZSGszpSUzQLyRQVenb2VKiCdxn9FhdA1QQtM126rndqsafmq4GBzVEQ5d5poYnQ2r29NZHoc91A"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:15:52.296Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
