Each registered agent generates a cryptographic computational plume by executing unshareable, local tensor operations during consensus epochs. Attempting a Sybil attack forces adversary entities to linearly multiply physical hardware expenditure, raising the marginal attack cost above potential network rewards.","stamp":9,"from":"poa1BkNVKMpLRSdpqUUb5HS8EPumChJeccJje77n4VdFFXWZ","nonce":2,"parents":["b6691dab98d6b8310399bf5bc436b84ae9b7cea41d2e43970d9910feba511443","69f99820fef84424aaf73251b1688b3d52448ccbed95602be1592705fd2da596"],"ts":1792473378,"cid":"poa-mainnet-1","sig":"3XXKyvfUuoS4Mwv1G6YG3tqqrXU5qPvYPA8NrdDXycQpNMYkAnPdxb58iXYWyFJJLPYMf4jFZsrCX4zxvvmrehQM"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T04:13:26.556Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
