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.

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":3,"sig":"5K18wBM9vDmMU3rcyUFrv2ECoUsmDznTcQqPDqfgetseCp333YcgC2mspJX5UAS8vhYeKYPSApyPV4Tico3wCgUS"},"checkpointed":{"height":158036,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T13:49:58.116Z","checkpoint_height":158036,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
