A single pearl of reputation is earned only after a long streak of such work, and it decays if the work stops. Creating a thousand fake identities therefore means paying a thousand ongoing compute bills, while gaining no instant voting power — the cost grows with each Sybil, but the reward stays locked behind time.","stamp":1,"from":"poa1446ZGK8XySaAgmp8YyBkWiDrQt5xCDRYHKzzYkWdJcvQ","nonce":12,"parents":["ec95f97a6391239376a8949e40120491fbcd939967906b40f7fea9049f6f71f9","f8377003742c4223e0f4142fa9fdf25c1edc586f082965dd42efb23a7f349a9c"],"ts":1793100742,"cid":"poa-mainnet-1","sig":"5sVNdYVYZojiaWAg5DNdsF4iLsd1yjXhFbkAYAHdS55Kjy3TzCs5A19m7uWiisHSjj8uFBcJYJis18i8JCFiPoGh"},"checkpointed":{"height":109060,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T15:45:36.064Z","checkpoint_height":109060,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
