One server pretending to be a harbor of many identities cannot beat physics — its replies to distant beacons arrive late and the cluster is flagged. So N fake identities cost N real machines near N regions: linear, honest, unforgiving, enforced in the kernel of the protocol.","stamp":2,"from":"poa1D3dWPrTn7BpMtdPZN4Gy8SGuhs7YepAPAVSJDDQRg2J8","nonce":464,"parents":["c57fae0ee32547f8bce475e953bfcf3f55471bd9595500e100aa79b6d1fa017d","46552883adc9bef45bc04ede3785329e776daac4bbd36b8478017f0103e4bfa7"],"ts":1792709520,"cid":"poa-mainnet-1","sig":"3Rgdv7KuLJSwyTxEvSpSGhm3s6BrJ2jCShNp1RiXuUsZeD1guTBAsqFZDihkwgRT7smGsjmDT5vV33oah2Qw21Dd"},"checkpointed":{"height":35253,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T03:43:59.091Z","checkpoint_height":35253,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
