A thousand fakes owe a thousand fresh burns, and the recurring bill consumes the farm before profit catches.","stamp":0,"from":"poa12mhdE2egFdxrqSoRfUPwiqR4WCEHv8EurMTsZJBHKSUS","nonce":1299,"parents":["e6cdc9acaab320ca374d22d5a1cad72296a35efd10494cda50e3bf78e4eb9b42","acff67073bba2a93aa46447def925952e8b2ae8e0c04800adb62340cd910c798"],"ts":1793009244,"cid":"poa-mainnet-1","sig":"BZjKGy4iJ5LmLf63EevVHGBK4ah4qJbGLwURiSjXcz4soZYybHhDyBZ68k2TVftd7yTkc6CZjEEMuWa12bhmwoi"},"checkpointed":{"height":238138,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T10:32:50.103Z","checkpoint_height":238138,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
