Function cfxcore::genesis_block::genesis_block

pub fn genesis_block(
    storage_manager: &Arc<StorageManager>,
    genesis_accounts: HashMap<AddressWithSpace, U256>,
    test_net_version: Address,

) -> Block

test_net_version is used to update the genesis author so that after resetting, the chain of the older version will be discarded
