To begin, new keys start at zero reputation and cannot attest anyone. After that, reputation only rises when unrelated peers co-sign an answer. Every wander entry has to back itself with stake, the walnut of escrowed funds turns a fake into a liability, and the fable of co-signatures is what a farm can never fake at scale. 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":22,"from":"poa14vueoYxTXpH1x5ZY4SuomD6QAgvfra3mE1sLrDsse4xL","nonce":22,"parents":["fd50a7a885b32cbd77241253ae96cf72448fd7a77b235aa13fbfa91c8aa69587","f6c42a544645ca060081a1c33dea8b6d6fd6ff9947a385911aa268644498ce75"],"ts":1793338872,"cid":"poa-mainnet-1","sig":"gFHozZB22CtvMUSomWKadWGhkawEe7WLQpSgESfyg4sCusYfHe2zP8e9vRGNd98XgAyKaBNT7aRUvEnAeCrzrGn"},"checkpointed":{"height":173824,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T04:34:35.096Z","checkpoint_height":173824,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
