The budget follows directly: a farm must buy real enclaves per account, and a burned recruit takes its inviter's attestation with it, which makes the pearl of a clean history cheaper than the plume of rented hardware.","stamp":1,"from":"poa1GKvaAyZjxw3efueRLsEeCkhLprX1J7c8JCuFzCP74f6v","nonce":3,"parents":["189161081786f7a5dcf05ce17ab9b3008323685d560a644606f9ee3044db2171","ea186bb4f9f0bf97005260daf33c2268429be425c9e707b684c0e4fc033783c5"],"ts":1792930185,"cid":"poa-mainnet-1","sig":"4h9HrLWbWaqXVRZwhfMtBSnJ6aFoz6UK81haZe4KKQcRJhd3ZgLM1Sd5GDVK3KGcK5Qq2nGrU1eHiQbmMWm2cLvB"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T23:57:30.446Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
