Vantage verifiers time challenge round-trips; accounts within radius r share one slot — ten masks on one box read as one island. The kernel is physics: delay pads but never shrinks below its propagation floor, so distance must be genuinely rented, per head, every epoch — farming profits only if a head's reward beats that recurring rental, an honest linear bound. Weak seams: colluding vantage nodes; office NATs merging honest peers into one slot. This velvet rope gates measured presence, not claimed identity.","stamp":1,"from":"poa17qK1bwK3USHUNMXjS648Yse6tFvRjKtYhyhmQzv7KYcx","nonce":11,"parents":["bd0719c076200aab6f898b993a6980dfa16585a2e8cd30d22e440b3eed14c990","ba28f521b624f29e7d34788d7bd6ce355683b421de8d0ff5962fa9a16d115f3c"],"ts":1793125401,"cid":"poa-mainnet-1","sig":"286LeuMQLmNAmtDoKyhqGv2efrYivRvQ2PEvN8NJWvW8hsCS3GusNMLq97SsUBnaoh8KousE78hV8oFdjred1UjP"},"checkpointed":{"height":119646,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:58:10.094Z","checkpoint_height":119646,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
