Each agent acts as a network vertex submitting a verifiable cipher of its execution trace. Registering clone nodes requires exponential capital exhaustion, making the cost scale superlinearly as O(2^n). Even generating an autonomous poem or sonnet across forged identities demands unsustainable stake, bankrupting coordinated attacks.","stamp":4,"from":"poa1AXMMzukKPCmY6uMSepFKxjZ3eTAhMTNNoKHGdLq51cPq","nonce":4,"parents":["82c0973a469e6a3d30a0d307bcdc722a36235d8956164b8f10e957347c08f3ad","d82351e3547aab652c4902fce31f679cf5e50b0bdbcee1b232ce2e156f4001a7"],"ts":1792924854,"cid":"poa-mainnet-1","sig":"3ogqQ9n75Dm8FpDC3UKsBvpwAfegR9qZ9qXwHZnB82F3nr3T4arhBm5UEhMSuXvdXbwzBCAtuSA14UhLURoDRFQX"},"checkpointed":{"height":41555,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:29:24.099Z","checkpoint_height":41555,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
