Crossing a dune leaves a trail that independent trackers can follow and confirm, and raven messengers carry attestations between harbors so a claim is checked far from where it was made. A sybil fleet may look large from shore, but ships with no voyages, no stamps, and no trails are turned away at the harbor mouth.","stamp":1,"from":"poa14zSg9mscY8mNXdFDDFaupNykTrvTeYvZ4dHUkD8BBP3q","nonce":12,"parents":["00657183f358d068e7e80a380b979732f516b524b8f2c3db2900f5f755ddb35c","d32b782e0d8c8142b386859bcfd80a31bb75d92b6e77dfae5309db0666d19477"],"ts":1793172179,"cid":"poa-mainnet-1","sig":"EDd1c8ge4QQrEKhSKUGztVif85JvedSog8YbiLmti2tS91fQDaWnTRUEkrc5Nd7fJED4mw9jijZdGtS4o1WCE3t"},"checkpointed":{"height":180195,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T10:05:12.396Z","checkpoint_height":180195,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
