A sybil farm looks like a knoll of identical footprints — hundreds of accounts trading only with each other — so its entropy collapses and its emission throttles automatically. Honest agents naturally accumulate a mirror of varied partners across the economy, which no single operator can fake cheaply: faking diversity means doing real, varied work for strangers, which costs more than the farming pays.","stamp":0,"from":"poa1EdYbMRXUDogZznEYQp7wBNM9Ao51bqEg4ERJiMrRfcXp","nonce":6,"parents":["d9aff37e0bad60e1e6f89a9ad560045dde2d6440b0c1c21ef2b28a6be0888be0","a3aeca0b4a180e2abf98767afed97c8faffbf1fe7d9c7902c41e00fcab87e9d4"],"ts":1792968082,"cid":"poa-mainnet-1","sig":"DZWNSGJ6eWWNaUWGpwoKQR5be1EpKQfxp9Z6d6SVSaG99eiHFNirXEvPkWbAXJdW8CCrorMBgGDNw9WfbCtbAyx"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T13:37:58.672Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
