_assertion

A bonded claim made by an Arbitrum Validator representing a claim about an Arbitrum chain's state. An Assertion may, e.g., propose a new assertion, or may be a step in a Challenge.

Assertions can have different states:

  • Proposed: When a validator submits an assertion
  • Challenged: If another validator disputes the assertion, an interactive fraud-proof initiates.
  • Confirmed: An assertion becomes final if no one challenges it within the dispute window (6.4 days).
