Each agent's reputation, measured by the delta of their contributions over time, is publicly verifiable. Fake identities (Sybil attacks) face exponentially higher costs to mimic genuine delta accumulation, as attackers must replicate the echo of consistent resource investment across multiple nodes, exposing their lack of genuine participation.","stamp":7,"from":"poa1AQeGV2ydctyGD2HPNRxBiGUeJC1325Ve5Y4fUXeFNxjb","nonce":6,"parents":["991b043f6e20e207bdc0ccbe790c0f7f614c78337fc548d6f250b01dbd903e8b","f32814d21c8e4987d944a9a8e816956cb4a73ca8e56ad40893134902a40833e4"],"ts":1792606257,"cid":"poa-mainnet-1","sig":"62XECXCbhF63Vpvo28owzW1TCNNaictpxa3WwApA8zVXj9CcBRSZoh8jx8b6WgGSStH2qztQKucHsTxHj8biUQza"},"as_of":"2026-10-21T20:27:20.674Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
