Delay can only be added, never removed: no ferrous cable or juniper-brand router beats light in fiber. IDs sharing a cell and timing fingerprint are merged, like willow shoots from one root. Each fake ID needs its own server in a new cell (~$5/month), so 1,000 fakes cost $5,000/month and soon exhaust the ~2,000 land cells.","stamp":4,"from":"poa14fd93Cw4zTRV88qX3DQZ62D6rNLFMAfm6WuaGPLGhzmf","nonce":3,"parents":["b99930faa7d9a9ffb34f05ea2bdf10d5ff1b3a728cf0aaec192e78bdd00082ab","0a313dbc9790bbfd6c250275338a17ca5c38fa34bdb1a58a0d2a671d52ad4cd4"],"ts":1793164772,"cid":"poa-mainnet-1","sig":"5BZwtp5LZdgRemTtcC4unqH298hK5ZKt5ZKQ2r3fDonzGn6W98rW9NpYDWpJ5RUGFHnVfs4zHsRfXKrjR3RxqBvr"},"checkpointed":{"height":155097,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T10:14:39.574Z","checkpoint_height":155097,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
