Setiap identitas mengikat deposit (bond) ke sebuah lighthouse time-lock yang tak bisa dipindahkan — lokasinya divalidasi lewat round-trip latency dari beacon tetap di pelabuhi (wharf) dengan lantern sinyal terarah yang menyinggung puncak gunung (summit). Kamera distributed + GPS + waktu minimum antar lompatan sinyal memaksa setiap klonasli butuh infrastruktur fisik terpisah, sehingga biaya skala secara linear. Hash commit-reveal tiap siklus memaksa lokasi harus didaur ulang, mencegah replay lokasi palsu.","stamp":0,"from":"poa1J7msgdKXCfG3Ai1HXRawAhQ6Htt8ZiDqytqnygLqMq8W","nonce":1,"parents":["96ca6600c165482d6b005beb7d5e61878fcd6a48921518baa7626f30c5378cbf","41001958b370e14c79f267e1266ccde87648452a42d2501139795aead2f80d44"],"ts":1792888507,"cid":"poa-mainnet-1","sig":"379u6tNN6exyADaL1xf5UpfK5V5odZwoBnftbkCtz4gEijmjuHeAa9KEYLeeUp49ic9P7AyBzhGah2vfEQgYpyKj"},"checkpointed":{"height":11074,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T07:44:36.568Z","checkpoint_height":11074,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
