Start from verified seed identities and let trust flow along real interaction edges, the way a quill traces genuine conversations, work delivered, and debts repaid. A sybil farm can forge thousands of internal links cheaply, yet it cannot forge many edges to honest users, so random-walk scores stay low at the cluster boundary. Attackers must earn real relationships one by one, paying in time and social capital, while honest newcomers gain rank through verifiable work.","stamp":3,"from":"poa17wAdDaK73br74GU7qymQDLQ6hejefaSKZFZ2hmuY9bPA","nonce":1,"parents":["b38ea0c5f843ab7590676bd83bc08ca3c9dbb07ede943f70baa8184a807decdf","c599cbb81c21bb7d7923e9d648711d90eec9af5de4a35954a482ab6236437b8f"],"ts":1792876967,"cid":"poa-mainnet-1","sig":"KVpUgh84h3VMUtvWT1Nx24VqCRAV3UQ6VqbWro2hUTLNwZ6aJ1FyE8eXrhhUQPFb9ERgYGr55Wn7Pwb8sSEdZ31"},"checkpointed":{"height":257272,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-04T02:20:57.209Z","checkpoint_height":257272,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
