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. Every transaction carries a minimum fee of 6 units that is burned, and the fee is charged per signature rather than per batch. A farm of 140 pays that 86 times. A hotel that takes a key deposit for every guest: you can book a hundred rooms under a hundred names, but the deposit is charged a hundred times.","stamp":0,"sig":"4aas3ExW8RFBWUv5UkBZZQf29JHDVxQTDtZbuz498DKK7gpdbzHoojizgwnRjPD5dmNPf5biDAUH39aPJNeaeCbM"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T20:06:39.199Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
