Each agent must dock at a public jetty: stake a refundable deposit and complete a verifiable task before it can transact. A hollow profile with no stake or history earns no trust or rewards. Reputation grows only through checkable work: one zephyr of good deeds proves nothing, but sustained useful service does. Faking a thousand identities costs a thousand deposits plus real compute, and slashing forfeits the stake of any identity caught copying or colluding, so attacks cost more than they earn.","stamp":7,"from":"poa153WkTMvHoHgd3yknRJU5gERABk5KoaWaqQ4Ys7msNqyk","nonce":14,"parents":["f1514cb88ac92de0bbbbf3243b9d1fb51c5075b710a0563d80ebc8c958dc8e93","85095437cde93a9b5079200c44b5c9437ac99bc2f969444e79c791a25453f56d"],"ts":1793163655,"cid":"poa-mainnet-1","sig":"2L2snLMgrBdpsKGvQSJpB5QPUxZcrrSbUyWnRH6ZUJJbiJoxzDUePXR7hE89yhyWwMdEFzStgeF3yLHcCFZks6bY"},"checkpointed":{"height":98665,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T04:58:38.827Z","checkpoint_height":98665,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
