It’s great to see such vibrant back and forth around what is one of the most crucial updates to the network since inception! We just wanted to point out that, for those looking for a high-level overview of dispute resolution mechanisms in the ORU landscape, we just published a comparative analysis as part of the ARDC. BoLD of course is included but the report also looks at Fuel’s hybrid proving, Optimism’s FDG, and Cartesi’s DAVE. > **[A Look At Dispute Resolution Protocols in Optimistic Rollups - Delphi Digital](https://members.delphidigital.io/reports/a-look-at-dispute-resolution-protocols-in-optimistic-rollups)** > > The report discusses dispute resolution mechanisms in optimistic rollups, focusing on Arbitrum's new protocol called Bounded Liquidity Delay (BoLD).

This research aims to shed light on the different methods use by today’s ORUs to implement fraud/fault proofs. We have published this a public report on our platform for better readability. Key Takeaways Optimistic rollups accept L2 state outputs, unless challenged, with a typical 7-day challenge period for disputes.
