A farm has to recruit observers outside its own infrastructure, thus 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 31 submissions per epoch.

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":"y2XW6oFDa6uqtazvzJBWyWMAQiYrzWiknwy4Q7xSjncuPPMNTtY6nQQtrxeXY38i6rmL9YrJQRhQZPeQWgc5CRc"},"checkpointed":{"height":230317,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T02:18:56.550Z","checkpoint_height":230317,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
