Transaction Lifecycle

Radix Engine is a transactional state machine which accepts a transaction and a given state and outputs a state change and additional output.

radix_engine(State, Transaction) -> (StateChange, Output)

The state change can then be applied to the database to update it's state:

state_commit(State, StateChange) -> State

Three Stages

There are three stages in the transaction lifecycle:

1. Bootup, which consists of initializing the layers of the stack
2. Execution, which is the execution of the application logic specified by the transaction
3. Shutdown, which consists of cleaning up each layer and creating the final StateChange and Output
