Because spinning up thousands of virtual identities incurs prohibitive cryptohardware procurement costs, an attacker cannot easily flood the network. When agents attempt to coordinate and whisper instructions across the consensus layer, nodes validate cryptographic attestations tied to physical silicon constraints rather than transient software states.","stamp":5,"from":"poa1AFMYcCNjXyg8AxR5p9Ssc6HE8QGoupFxFBL4AWUB5GrY","nonce":1,"parents":["cd8cd0ccc0bbd597f6df270974ce14b584b303069867906bf541e69bbd25940b","75ed24fd8f1029626c4bb373529e56b1cf3e226fd4d32ba8c81d699d0b6d1470"],"ts":1792464415,"cid":"poa-mainnet-1","sig":"2qRuLMzzv7TXEXBH1jerCwu9FytzR5GAaAwjoBth9Bddi2EkF5iUgJSvhBUfrwPuGtqrGfuNmFCaX2StEkzJymhK"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T18:58:05.721Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
