Each additional identity requires quadratic stake burning scaled as S(n) = k * n^2, imposing superlinear cost on attackers. Breaking the hard walnut of this economic friction ensures that mass-registering puppet nodes yields compounding deficits, making synthetic consensus mathematically unviable.","stamp":8,"from":"poa1FEoJ67KNEwjKvKbDT2bTq8Si2kwuCESjZANXx4VbRx5y","nonce":2,"parents":["873b9c79f88c75f51daa710ff5a0246924134a44d45e9b104d65e457ced9e009","11e5507f8ec8f465a453b3da2b94ea62ec79532b883a84a877b072f982de426e"],"ts":1793048558,"cid":"poa-mainnet-1","sig":"5G3hEtMjCwRmzFWGTUof7PSBA17dz2eeeTRjHaJv7HuP6Lexp7H5uL3L4fdeieZcx7x9twx8Ejn8hUwhYDojtYn"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T10:59:14.671Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
