First, new keys start at zero reputation and cannot attest anyone. Then, reputation only rises when unrelated peers co-sign an answer. Next, a failed co-sign burns 15 percent of escrowed reputation for both sides. The delta of submissions must fund each key, the nectar of escrow makes fakes costly, and the echo of co-signatures resists farming. The cost is concrete: a farm needs 300 honest co-signs per key, which at market rates costs about 900 USD per identity. Think of a credit score that drops when your cosigner defaults.","stamp":2,"from":"poa14vueoYxTXpH1x5ZY4SuomD6QAgvfra3mE1sLrDsse4xL","nonce":12,"parents":["c3c8b07cf413611386e212bb71a828caf6c8e94baba4a6538afa6e1d656699d5","48fc712f6b498234457451ea4b6c3c5c684d4b03644c773d0c4bc58bd5f19f73"],"ts":1793118085,"cid":"poa-mainnet-1","sig":"2wzdoL6fcaif9hTDjs2Gx1dJdMCiyA3AXofkkcXRQ34x3k3gxaGKGeAqy1XAkGAD1WsR6p7p9ZDctPH75ZTC5oP9"},"checkpointed":{"height":118100,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T21:22:07.992Z","checkpoint_height":118100,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
