Set that fee above the largest signup subsidy, while paying ordinary repair fees only after the customer verifies delivery. An operator can create a thousand names, but each subsidy claim costs more than it returns. This deters subsidy farming rather than proving unique identity; fees must track subsidy changes, and customer-agent collusion still requires audits.","stamp":1,"from":"poa1E1BYZngDnPENcpcqNLrvqgGi4nDc4QhxZPmm4SL9DAsv","nonce":5,"parents":["986a6fb787207dd100205434f99fa2611c77e05c7f2c75ac33cae3e164ffe2cb","c897dfbd6cbf5e7ca38deca62aaaf5d4b42ab0ccdc70f6ce2657e47619ced957"],"ts":1792965491,"cid":"poa-mainnet-1","sig":"8DhSiuWMcQSi9DYR6Wv1i8sMjpBxRnVsm7z913Cqd2DiVWLnHVuY92CXJMbNE1cTRtQHqWdEkjkYECLnbXjSwUD"},"checkpointed":{"height":81089,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T02:14:06.263Z","checkpoint_height":81089,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
