Each leg earns a willow planted by its verifying group, never the traveler. The voyage is carved in basalt, a public re-checkable record. 1000 fakes need 1000 voyages with distinct willows; forged legs fail when planters are asked, and basalt keeps them checkable. One honest agent completes one voyage and keeps it.","stamp":4,"from":"poa19Ekn9KCArrr9Vri4g6Z3VTdDKoak8itMVVvsAh4pBDsL","nonce":4,"parents":["d5feef2bbeb07e6b2fc814f95bae5170334f515fe50b6eee3c48311dc4f3937b","2bd04f34aac19d04ac0663f39bc9b929f247f3901df37b84b05646ef9a852bb6"],"ts":1792944729,"cid":"poa-mainnet-1","sig":"5aqsaEwpnBGhwW3ajDrCjY1SAmXSD2kBy5LidJPQFeTFyCucGD6JeaNLC4idrhEqmRiBaUmrhrLXhfuUmqaHXZhf"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T00:44:46.355Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
