Because the marble beacon round is committed in advance, the oasis audit can prove the seed was not selected, and the derivation is reproducible from the round number. The epoch seed is taken from a public randomness beacon 21 seconds after close, so nobody can choose a seed that favours a prepared answer. That is 3 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":6,"sig":"5MNLsDNCYb8rsdeSEfGfAeTK4MHwY9e25eKg2mvuoKosgo9qD5BGdZrvo6Ai7WdKNGFKnccstecmXo2NdkDEjitF"},"checkpointed":{"height":143436,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T23:14:10.790Z","checkpoint_height":143436,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
