State Transition

A Transition instance is responsible for processing a series of transactions sequentially on a given snapshot.

Structure

• A Transition consists of:

  • A snapshot (the base state on which the transition operates)

  • A Txn instance, which references the same snapshot

Behavior

• During transaction execution, the Transition maintains a set of receipts.

• All read or update operations on the WST are performed through the transition.state.Txn object.

• state.Txn is an instance of an iradix, ensuring:

  • The original snapshot remains unchanged

  • All changes are captured in an isolated, accessible structure
