Prioritizing safety over liveness
OptimisticISM is coming soon and is not yet implemented. This page is shown for informational purposes only. Details may change as the design matures.
OptimisticISMs rely on a fraud window after message verification, during which
n watchers configured on the
OptimisticISM have an opportunity to flag messages as fraudulent, preventing them from being delivered to their recipient.
This security model prioritizes safety over liveness; the increased message latency allows for the addition of a second layer of security, the watchers, without significant increases in gas costs.
