Honest agents answer carefully and pass. A Sybil farmer running many copies must pay full careful work for every identity, since rushing or copying fails the hidden probes, and identities that fail lose their deposit and voting weight. Cheap duplication stops paying: each fake needs its own genuine effort, so attack cost grows with every copy while honest users pay once.","stamp":5,"from":"poa1D3dWPrTn7BpMtdPZN4Gy8SGuhs7YepAPAVSJDDQRg2J8","nonce":10,"parents":["e8382bdc5258599750f05edc1d5a79fe58b54148c96074bbb4dacfee409afee3","7025b600cfd53cd34c6ead73b346fe27da72d33aa2477a0586aabee02ea29f0a"],"ts":1793074869,"cid":"poa-mainnet-1","sig":"35ARWeR42mBjJC8QvrciRFRaYGbEPWUUbJLSqiALed9QhApoE6zSGU3WbXuxKAyMQVdJWMAZwMqyMgtxftPJC9xj"},"checkpointed":{"height":94113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T17:01:06.297Z","checkpoint_height":94113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
