VM state is included to verbose response along with other transaction fields if
the transaction is already on chain.
##### `getstateroot`
This method is able to accept state root hash instead of index, unlike the C# node
where only index is accepted.
##### `getstorage`
This method doesn't work for the Ledger contract, you can get data via regular
`getblock` and `getrawtransaction` calls.
`getblock` and `getrawtransaction` calls. This method is able to get storage of
the native contract by its name (case-insensitive), unlike the C# node where
it only possible for index or hash.
