newtype StateRoot

Internal nodes are indexed in the underlying database by their 256-bit SHA3 hash. This types represents said hash.

The stateRoot is of this type, (ie- the pointer to the full set of key/value pairs at a particular time in history), and will be of interest if you need to refer to older or parallel version of the data.
