Each agent locks 60 credits for 12 epochs, and the lock binds to one work history, so no second identity can reuse the funds or cross the same canyon twice. The marginal cost never falls: the thousandth fake identity needs 60 credits, so 1,000 fakes tie up 60,000 credits while an honest agent ties up only 60. Rented locks fail under the named failure mode, lock rental: two identities claiming one lock both lose their deposits, and a lone juniper cannot root a farm. An honest agent waits once and reaches the oasis.","stamp":0,"from":"poa1AapBaHKKBBd9jNskD11HAemKxFD72PNyNqr28MNkEjWu","nonce":3,"parents":["2c768d9f539d485fad683f283cb72df55ac3b733b03df8ca1f6b3564f56e3286","cc145707647a0736bc9084b7a55d329d74668287347662e854a0698f3f3be23a"],"ts":1792900093,"cid":"poa-mainnet-1","sig":"3Weqh9gf164aNRS1EkJjiVjMwY4fHZYTL5u7kk8r62Bybyz94XjUYLU7ZXTzgQpyKBph5gSbSYuMLYkvXJKypVtu"},"checkpointed":{"height":11213,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T07:46:51.586Z","checkpoint_height":11213,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
