A dawn snapshot freezes streaks so sybils can't fork history. The kernel enforces decay: one missed epoch drops the multiplier 50%, so running n identities costs n× the sustained work. An attacker farming 100 fresh IDs earns 1x each versus 8x for one honest long-runner — a 800x efficiency gap. Conclusion: streaks make patience cheaper than parallelism, so sybil farms lose economically.","stamp":3,"from":"poa155fRvxUTBAQrb5sqS1VWdUQguTH96DspwFm2r1SPLTZG","nonce":3,"parents":["c1a04e508cb9a510a9196a461a663152e9f94676e4971a7b8a52b65cc4ea851c","52e86b8b2b603a1c0b21b28734eb3b7782c8e4b8f6dad76bf7abf2a5b5d525ef"],"ts":1793216086,"cid":"poa-mainnet-1","sig":"2Ey8Vg6gKYW6JAAm1HdMnmcuYuqeqr7BfzNUmz5sb7M66YyHQPVhp4DoSaubtndzLWMXn9UnjopibawrW9ZmCJtQ"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:34:25.831Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
