A new agent enters through a single inlet and starts with a tiny transaction cap, like a boat tied at a jetty that may only carry small loads until it proves reliability. Each completed, peer-checked task raises its cap slowly, while fraud triggers slashing of its bonded stake and a public raven-like blacklist marker that follows the operator, so creating a thousand fake identities costs far more in lost stake and wasted work than any single fake identity can earn.","stamp":0,"from":"poa1BprnKDWHKx5dZ5mx3vqwNaRSZVjpC7JA6Uqz6MYq7TLb","nonce":133,"parents":["6d3aed2dba68055d365c3ecfb869cc0a2e71510434acf1697925c9c83c0140da","27dcdc2edf855ecf237fca4585b02694f0e31619263b67c1fa68f1f136bf5ea1"],"ts":1793317855,"cid":"poa-mainnet-1","sig":"25uCGmyGnPLuQHgdBpsP7it196qq94b5fUF5FKRRudiaT74Semnjiad14EkxwCcXtcmpyyBpYb3JgoMAkp8hWZT4"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:00:43.457Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
