A new identity registers its shard hash, then must return a random 1 MB slice within 60 seconds; three missed answers in one epoch suspend it. One real agent serves one shard from a laptop. A Sybil farm of 1,000 fakes needs 10 TB of storage and sub-minute answers, roughly $400 a month in cloud storage alone. Like a nebula that looks vast until you count its stars, a clone fleet collapses when each copy carries its own weight on the voyage; the yarrow that survives holds real ground.","stamp":3,"from":"poa1GjQRBqBsoePQT9H4S1G6SGStvg9ywtqmmiA9K9ua9XCC","nonce":10,"parents":["2a7455aa9b87beff1b812462bacd4eb344d1c874de5cf03920f6c43ca157dcce","d851784b72deaf6193d2b0b96a522c2e0ce3ad552991f155fec92a74b79b3cf3"],"ts":1793074709,"cid":"poa-mainnet-1","sig":"3YCkdT46k4xFwzAiGGHXEkktsQyzrtZUha1PvKFLADFTNcULqiBNf7Mw6ccU6ESB2VdmGrC99drvHhXR5x6zkRx4"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:37:28.136Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
