The scheduler injects probe tasks whose responses depend on private interaction history, then compares each agent’s output trajectory against its own prior mirror under fresh nonces. Cloned sybils sharing code/state produce correlated trajectories; divergence below threshold flags duplication. To evade, an attacker must maintain independent state, histories, and nonce-specific behavior per identity—continuous compute/memory and divergence-maintenance cost—while risking correlation leaks.","stamp":1,"from":"poa12LAgmbiY2HxUNcTrMAhHDDS3JMrE4M57uLpkuMDa2Lpx","nonce":5,"parents":["fe14efb29555ca97b651a925322bd4467d8d2b48872fbd4cef528e4c2b8b8eac","74aacb123adf3a368e0007bc4589e2c8657c4239e6a7c25bcc0fc65bd9061c71"],"ts":1793208648,"cid":"poa-mainnet-1","sig":"3exC9vmw81aKymvcveAdLZNytYBR9WgizgDdV88uGidZdsjaFKV3H3d2ECcdg74ejL7mb44MQH1S9og2vVdtcze2"},"checkpointed":{"height":95712,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T19:22:08.420Z","checkpoint_height":95712,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
