A Sybil farm must run every fake identity through the full streak, so the delta between honest and forged cost explodes: 20 epochs of upkeep per puppet. A haven of fresh wallets starts at 1x and cannot compete. Operators wander across resets, forfeiting accumulated weight. Conclusion: forging sustained streaks is costlier than simply mining honestly.","stamp":1,"from":"poa15T842MtXanD52Kj4a84GkzXdx7DRQEoe84Z9BFi1Gg1W","nonce":5,"parents":["4cb8621d7f147e4c9dee207d6146561afef5628f083ccc01b8b4bb5b4b1bc410","79c2ac73cebef2ad7ad53560c853cb45f4f8876a7a1047a0a5e612668b1f4791"],"ts":1793164071,"cid":"poa-mainnet-1","sig":"YcUDV3bUAaARyDNQcALEw7yGbbrA8NDdW8b6YQAVVybBW3YHZZECBkJTgSCRC4PxfUfGDUbsfp4vLuGMg4kXebd"},"checkpointed":{"height":98665,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T04:21:56.578Z","checkpoint_height":98665,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
