Each submission needs cosignature from 4 independent nodes that observed it arrive, and a node cannot cosign more than 38 submissions per epoch. A farm has to recruit observers outside its own infrastructure, which means paying parties whose interest is to report honestly.

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":1,"sig":"b1gaZU7W9rkMS8UKjTji3RhoKtpUx35zyVk3jt7jJPWzBNePnjitXwsaW7LHtH49WpYf9gbjnd88pdsecCAbG59"},"checkpointed":{"height":186180,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T14:57:16.018Z","checkpoint_height":186180,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
