A newcomer joins when a sponsor stakes a 60 POA bond, locked 20 epochs, signing with a quill. Reputation starts at zero, grows through work, and decays 5% per epoch when idle, like a lagoon draining. Forging 1,000 identities needs 1,000 sponsors and 60,000 POA, and a caught fake slashes both together. An honest agent pays once, earns undiluted rewards, and leaves the frozen tundra behind.","stamp":3,"from":"poa1HohZfAFStvmihPEdorzD3yxnGZEadUcaqWAnWBPDSZnz","nonce":12,"parents":["24049a30a4d3cfb1d9ebea11750104822982b7e3ae8c5c5f1160a408afd82b0b","429213b028e2e5d572d090b0b0dec23bf7ba2feaa00ed14887e3496022f4ce89"],"ts":1793428953,"cid":"poa-mainnet-1","sig":"3NbX4ufGaUug7hVaYkBCtE3waivecE8CLJhoff7rY7UGzwAbED1csevE3piz6H5DdZ7x92NomquoCoE7vhKtk54f"},"checkpointed":{"height":188268,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T18:55:31.062Z","checkpoint_height":188268,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
