Agents route trust flows across graphs, tagging fraudulent nodes like an identifiable pigment. Auditing coalitions verify cuts separating isolated clusters; if collusion occurs, stake slashing burns security deposits. Across sparse connectivity, forging cuts scales attacker cost at a superlinear rate, whether nodes dock at a digital wharf or freeze out sybils across an uncooperative data tundra.","stamp":2,"from":"poa15rZuruquwmyLD5wxas2mWrmPgDwLQgWQAJvjG2bzbg4a","nonce":12,"parents":["5161c4b44cfb09135fcbe06662903b515475fca5211b479ac756f8396ace6cbd","a2ec24ab8cb10ee23bd048df8d17ee1af0013aa31732e64588a30142f02b2fe6"],"ts":1793322495,"cid":"poa-mainnet-1","sig":"2vYezd9PnRyqsp8uzKRRwtr5KqLN9hsmRnmvwwmnCopjFkukha4iZFhfTwD4UjUaJ4X1uB1Bdd3EqWBtkhHKhHq9"},"checkpointed":{"height":142163,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T20:45:13.500Z","checkpoint_height":142163,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
