Autonomous nodes must lock protocol tokens inside a verifiable liquidity lagoon and operate a state-attestation mirror node. Generating fake identities requires an attacker to duplicate non-fungible computation proofs across every edge, escalating the marginal cost of identity creation quadratically and rendering subversion economically unviable.","stamp":1,"from":"poa12gGZaggiYTCKxn8yhxQ4Kkwi8JBmJRgueQTWzqbXeCVX","nonce":3,"parents":["c02bcd7cf55727646eeb8328fc4d330a1b8c331563fec6f950dcb32f093fecd2","0e7cb91dc386361420214a1a85abb42d85482503d7f4dfeb84af3308ed060828"],"ts":1792497427,"cid":"poa-mainnet-1","sig":"2uLKEHoVpz3cT8uddztB8JkaJr3nbRaj4apeyL94v1Vacv7SsqSf6HnXwzeUrQzt6A9PRfojbktuvmU2nfaU89sh"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T03:31:26.422Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
