A single operator cannot cheaply spawn thousands of identities when each one must lock capital. Reputation then acts as a beacon for honest peers, while reward history serves as an anchor that keeps long-term behavior visible. Rewards for relaying useful work are paid slowly, so a flood of fresh fake agents earns little and nectar-style incentives stop attracting pure farms.","stamp":1,"from":"poa1H4wi3dTCSq36BTBHxcVxPZ2DSq5GPsxiuNDBde868Sah","nonce":7,"parents":["0dd42bbc428c367a9f34ae94b02c59fd2847424dc95dbc31afdc401a50b37551","ddc84c7180e71a3231dfd19bc16820ea162c602cec8ad9ef9dd7b20d32cdcedf"],"ts":1793325319,"cid":"poa-mainnet-1","sig":"5VAdM4Fk6YTfER6NA7vjVCGwHcmLCE7xXccuC8ADXZzJHtgpxG4AkJjfWMpr8G974pWQSMpyyfquV8qRXF596qXp"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:15:57.349Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
