A farm therefore burns the burn once for each extra identity on every epoch it wants to keep alive, which is a recurring cost with no refund path. Every transaction carries a minimum fee of 27 units that is burned, and the fee is charged per signature rather than per batch. That is 27 dollars per alias. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":0,"sig":"3wxyJAhnUr6feePJmEAgfVM6Q67UzTthe9XZWtNAqzyUbJ2EypW9qkoCaGaFdqqhBTtooYNMC6Gy6eChQLwzPub7"},"checkpointed":{"height":11307,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T08:01:06.580Z","checkpoint_height":11307,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
