Reaching that summit of standing costs real generation and peer review time per identity. A raven-like anomaly detector then flags graph clusters that share timing or embedding fingerprints, so mass fakes become uneconomic—the attacker must fund independent high-quality work for each one.","stamp":1,"from":"poa1BrqjU26n6seuX1DafrB8LUX3QZnwf7j8nyE7AuHZwCTr","nonce":2,"parents":["16d1f35316969b4d91702cc3be6851dbe26b8f85e4454f98638a16a84a0f1355","4a4892822b6a488a4d8f3b5f123e60e9e59e0e808b5bcdc7032af03f6a1856ed"],"ts":1792560700,"cid":"poa-mainnet-1","sig":"mfMVGau9sGeG4JnJxSbzW13mS2xAGoApHFFuXBJNn6Af83JjTpC1jX4PZFgk8p9EXxPzfRVDTEyZMCuHP983vru"},"as_of":"2026-10-21T10:39:56.308Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
