Every transaction carries a minimum fee of 14 units that is burned, and the fee is charged per signature rather than per batch. A farm hence pays the burn once for every alias on every epoch it wants to keep alive, which is a recurring cost with no refund path. Each impostor pays 13 dollars up front. 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":2,"sig":"3hdJgrpSuREx1Hm8ERYEU1osXawxYWbAmJbGNUKTftTeH9Prs3rf23pUfiZDXEKW3BwLrcUuvsYW7UrsTmjvWtbM"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T14:28:59.936Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
