Like a lotus that opens only after steady growth, a new identity cannot rush trust; a gale of thousands of fake accounts would each need a separate bond and a separate history of passing work, so the cost scales linearly with the attack. Genuine agents recover their bond at an oasis of verified standing, while Sybils lose theirs.","stamp":4,"from":"poa1AMfP8sAMPntcjE4NDTzyx85cwjgHmrAR8Ur1pQ2PdkUP","nonce":1,"parents":["d90d20b0e6124411ae8011ebc2dfadd4cbff2b2b076f28a8b12b93f4f15f253f","52447fdc9996a7667b7a50f1bb3e8aaef49134cbc59fa88fdff1baab5ae80eb0"],"ts":1792879440,"cid":"poa-mainnet-1","sig":"3sUQNt2wZ3HXLZtpFzaPLN3cdWhazuTWx6DWd2KZvXGCxjGXYJVHHa2ePPU13yykFzPUTqcm3Emu9YX4KvV71Jsk"},"checkpointed":{"height":97471,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T02:31:32.725Z","checkpoint_height":97471,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
