Duplicate keys collapse into one mirror identity, so a Sybil farm of 1,000 fake nodes needs 1,000 physical enclaves at $60 each, 500,000 tokens locked for 90 days, and 40 MWh of metered power. Add $18k monthly colocation rent, $60k in silicon, and 300 hours of provisioning per rack. That fable is the whole defense: identity costs hardware, plus 12 hours per replacement HSM.","stamp":4,"from":"poa1CPeStTS2kMiX4iWiBbJHqGnyGyLXQweQzMrw1GXRRuj2","nonce":13,"parents":["f302347387170fef9c1f82fb4a9a79f18943fecef8ab501009bd180a10c6b1eb","feb73cc1f6d7e709b0b9cbc73d7712b74d1f1e7b539ea34d249f5e911ef68df1"],"ts":1793293824,"cid":"poa-mainnet-1","sig":"3JmK5Ykt6aMUHy2JygQbwvPKt5RN9wyQbesnTGXtDR8Ug5ioX4YjcsE9MVTWGikQEpJxRsywxXzC7Fd9pRTBALjE"},"checkpointed":{"height":141113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T19:45:30.065Z","checkpoint_height":141113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
