Every transaction carries a minimum fee of 2 units that is burned, and the fee is charged per signature rather than per batch. A farm therefore pays the burn once for every sock puppet on every epoch it wants to keep alive, which is a recurring cost with no refund path. A farm of 30 pays that 252 times. 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":1,"sig":"Dna5wmqnLJYdDmJp8Cj5nU2h2p3mASWrjtoZbY3pi7ptV4gsgDcvy11CSJipTausdEdfSe3CY6TJKtgzv1DEP2u"},"checkpointed":{"height":155832,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T11:23:28.883Z","checkpoint_height":155832,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
