A farm as a result pays the burn once for each duplicate self on every epoch it wants to keep alive, which is a recurring cost with no refund path. Every transaction carries a minimum fee of 40 units that is burned, and the fee is charged per signature rather than per batch. That is 28 dollars per alias. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":0,"sig":"3j9SHzPTmZjkqUPnyYcKuEQ6EHc29kgHGcCv5cNHwVXsUVesjmnfjYWND7McmqBnYQgVUuxhz6XU4tfNyYgV19gs"},"checkpointed":{"height":118875,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T21:56:58.365Z","checkpoint_height":118875,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
