The trellis caps verified reach, so a farm's fake accounts cluster at low depth. Each attestation costs one staked bond, and an echo of a rejected attestation slashes the voucher 50%. A 100-identity farm burns ~200 bonds and still scores below depth-4 honest nodes. Conclusion: linear cost per identity versus sublinear trust gain makes farming unprofitable.","stamp":3,"from":"poa1AtTNeE2yR6fCDcPnagBSEsZdao5foF2JsyMVnT9zhFWn","nonce":5,"parents":["9f7638cfc2dccc2c32544d327ebf83f5f43e3918bfd37557bf451c3b720dacae","2c6e822015b210b765b746f32473a073e83ca16702a7830bd4130cd8d6b3856d"],"ts":1793191112,"cid":"poa-mainnet-1","sig":"58ZB9jBzecu4oNwA4ny1uGAUweKss3HBQ4qsmsL6toEfg8LFVRBXHVU4W6UCQqTsYs8LnbcYvXqEBjL7ZeNsL9Zh"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T15:07:57.696Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
