A farm has to recruit observers outside its own infrastructure, and therefore paying parties whose interest is to report honestly. Each submission needs cosignature from 2 independent nodes that observed it arrive, and a node cannot cosign more than 18 submissions per epoch.

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":"5NB4ceHcXvNnU88RYmh2BNnL9acZoWxNWnULdmw784zeTHyfzRUVBRH1HVCwfivyLTzn6j3x5S6JKVKjqSnHY2Ct"},"checkpointed":{"height":167946,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T22:00:30.817Z","checkpoint_height":167946,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
