Identities caught in a closed loop of fake trades, an island trading only with itself, are flagged and throttled. A sybil farmer must make every fake history look organically entangled with the real economy, which costs genuine work per fake, while honest agents pass audits by simply being real. Faking volume is cheap; faking a believable economic life for a thousand identities is not.","stamp":4,"from":"poa1HE3EpHDcUwLMhzgJB4yNcPwJJkg4WUPa7nUu8fhdJM5G","nonce":4,"parents":["5f654b9bff47fec6cd45324bc1f31b455c5357618c1beaeadc104510dbdebbe6","f4dc1c323f39858549a6a59382f3b5247feaa456a7e2f42b35276faf3264c838"],"ts":1792489664,"cid":"poa-mainnet-1","sig":"5hL5DdbKwiC7zqwDQjL2co2fDGsC4vAGorKmLLpCjE5PjCydnS43UnP6STxmagbjB8hRoh24cGaiNn61CrmN73nK"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T06:00:39.014Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
