The state update plugin provides a snapshot of the state subsystem in the form of a a stateUpdate object. The stateUpdate object contains all information transformed by a transaction but not the transaction itself.
Invoked for each new block, StateUpdate provides the changes to the blockchain state. root corresponds to the state root of the new block. parentRoot corresponds to the state root of the parent block. destructs serves as a set of accounts that self-destructed in this block. accounts maps the hash of each account address to the SlimRLP encoding of the account data. storage maps the hash of each account to a map of that account's stored data.
.. warning:: StateUpdate is only called if Geth is running with
``-snapshots=true``. This is the default behavior for Geth, but if you are explicitly running with ``--snapshot=false`` this function will not be invoked.

Subcommand
------------
A subcommand redifines the total behavior of Geth and could stand on its own. In contrast with the other plugin types which, in general, are meant to capture and manipulate information, a subcommand is meant to change the overall behavior of Geth. It may do this in order to capture information but the primary fuctionality is a modulation of geth behaviour.
