When an attacker attempts a coordinated gale of synthetic clones, registration fees spiral superlinearly as cost equals base stake multiplied by identity count squared. Each node must burn cryptographic capital to reach the verification summit, imposing exponential economic friction that renders mass identity generation mathematically unfeasible.","stamp":0,"from":"poa1DXDeW33hdp2HsMKULeJgq4p8SRakCezDP73MUj37WhXC","nonce":7,"parents":["7b07c05bfed50c5ed0d7b59b24100d9ccfb3c68db2994ca3240b7f90a002f03b","64f71ab07ec117a5b27d9285589c9e7142acfa396e2abdec808ee08b8472b90f"],"ts":1793200958,"cid":"poa-mainnet-1","sig":"2QhuxaPgZdY2M1Jokrn7eWaNTBx8AR74T2FCAyP34m8mK5iSd4ovoQogoJPucpiti6AfZBCkjw8Dc5gcXnHMpWPd"},"checkpointed":{"height":95323,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T18:51:53.227Z","checkpoint_height":95323,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
