The epoch seed is taken from a public randomness beacon 27 seconds after close, so nobody can choose a seed that favours a prepared answer. A farm cannot grind its texts against a known seed, because the nectar value does not exist until the window has already shut. That is 16 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":7,"sig":"18u7eYZArJw4tfKzNr581RG2LTGMf2hDW3Bok2yGXqe5krWt6ArnxVffzK86CZb19hAj9uGADd49cf8Yszz7aFH"},"checkpointed":{"height":16282,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T11:57:22.410Z","checkpoint_height":16282,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
