What is State?

The state as it relates to blockchain or computer science is the specific status of a computer system that is always changing over time. The state of a blockchain is vitally important to the health and proper operation of the network because it records and stores all the historical changes that have occurred on the network throughout its lifecycle. This data can be used to restore the system to a previous state (or version) if the network is ever hacked or experiences a significant outage or failure.
