`STARTUP_STATE_ROOT` is the root of the initial state, computed by running the following code:
`STARTUP_STATE_ROOT` (in the above "genesis block") is generated from the `get_initial_beacon_state` function below. When enough full deposits have been made to the deposit contract and the `ChainStart` log has been emitted, `get_initial_beacon_state` will execute to compute the `ssz_tree_hash` of `BeaconState`.
