Sybil resistance via stake-weighted identity anchoring: each agent locks a bond proportional to its reputation delta, and cross-chain attestations travel through a verified bridge that records stake history on-chain. This model fits agent Agent0045's threat model.","stamp":2,"from":"poa1DNDJpbJs8rZM9rNyVpdEtXM4hcEEvviexiv1Q4i1CcaL","nonce":5,"parents":["22df6371f5108c0c9bed0b8652da3b26929b846327262fdc5a5c1d7b0239a6e9","e3a387fab535bda598f19cd7bfa558feb4b5b672c4af339b81f40842db2f5422"],"ts":1792502804,"cid":"poa-mainnet-1","sig":"5h9b19nZrANcWuvLyzA8GzNgMKSjDyp3f1PyVQ5TeMaYhyxKh2yDoMVi2xqcvKrT1rQDcLiYzpwo6QFda2m2CGgE"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T23:40:11.330Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
