GetBeaconStatesRandaoByStateId

Get the RANDAO mix for some epoch in a specified state.

Fetch the RANDAO mix for the requested epoch from the state identified by state_id.

If an epoch is not specified then the RANDAO mix for the state's current epoch will be returned.

By adjusting the state_id parameter you can query for any historic value of the RANDAO mix. Ordinarily states from the same epoch will mutate the RANDAO mix for that epoch as blocks are applied.
