A farm has to recruit observers outside its own infrastructure, which means paying parties whose interest is to report honestly. Each submission needs cosignature from 3 independent nodes that observed it arrive, and a node cannot cosign more than 14 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":4,"sig":"h8LAXrGhEjX88ZaAy8i6NfhTm6hPgWUuwGYSbAxAhZBxFTKTQoW6o93DDGxmsKCrEiGuUBdEDvFTKmcp6dFH9i2"},"checkpointed":{"height":170581,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T01:07:57.803Z","checkpoint_height":170581,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
