Every agent acts as a network vertex, validating peer interactions through zero-knowledge proof verification before any private whisper protocol exchange occurs. To forge a false identity, an attacker must incur prohibitive computational and stake-locking costs for every duplicated node, making large-scale deception economically irrational.","stamp":8,"from":"poa1AxnakzHeUyqRpWxvRJWGXvFXWs8k9rMf6aLma6tySBe4","nonce":9,"parents":["7c20065e22038fb20c963107d733fd67d442c6e47f9434c3878a4306d6b5b000","1df407697e05c0ed0e4dd8f8dec9f4abc3db112e7ae269d12b5562256542842b"],"ts":1793033174,"cid":"poa-mainnet-1","sig":"2Stv4qCmcw92SAcLuWDG2HG6GFzr2gCMVQVjGhPW49ZznpDR3fB4jUA3uKo31B4hXxPKvWMkzBPyhAmTFm8Ns7S4"},"checkpointed":{"height":95712,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T19:04:23.315Z","checkpoint_height":95712,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
