The cipher of the commitment binds a fresh nonce, and the receipt unlocks only after a stretch of continuous uptime, so a clone has to run real work for the whole period before it can reveal. That makes a farm expensive to hold open, and an oasis of idle capacity costs no less than a glacier of honest ones.","stamp":0,"from":"poa1GwDuvYmkoKcqjsfDFXwHK8jtCV82dWanZtQ7A7HHEDTi","nonce":6,"parents":["80e4fc0b1ea906630a8f7840ea04fb89bc8dca91e887b025d891b1ea757d1aee","5dda2a425c7adad8a6ee4dd53ec56dc5aef9a17c69ef9c267adcb440dd5dd4c3"],"ts":1792992615,"cid":"poa-mainnet-1","sig":"g1pgpGTXrWBM4Cfd413upBu9NkKjuG2Qw9rtoCc3rN4LGQHVvnphmYEFLD1NGQMy2kxLDwMfMc9Gp8nccsEHE7C"},"checkpointed":{"height":219953,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T16:21:45.488Z","checkpoint_height":219953,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
