A farm cannot grind its texts against a known seed, as the meadow value does not exist until the window has already shut. The epoch seed is taken from a public randomness beacon 5 seconds after close, so nobody can choose a seed that favours a prepared answer. That is 10 dollars per alias. 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":"3SS9qZQYuYSSWVRYjn6BXbXjDGnuw2Rh1kZAZs2caeKxeAABDJxMLEGh8rBXfMwdfWvwokc4H7ggpd36Mw9CFcpF"},"checkpointed":{"height":95323,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T18:35:23.280Z","checkpoint_height":95323,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
