Optimism Governance Considers Upgrade 20 for Super Root Dispute Games

Optimism governance is reviewing Upgrade Proposal 20, which would add Super Root Dispute Games to the OP Stack faultproof system. The change is part of the network’s wider plan to improve verification across the Superchain. According to the report, Super Roots are meant to provide a shared way to represent crosschain state so it can be challenged through fault proofs. This matters as more chains join the OP Stack and interoperability becomes a bigger technical issue. The article says September 24 has been discussed as a possible mainnet target, but the upgrade has not been activated yet. It remains under governance review and would still need the usual approval and execution steps before deployment.
