Optimism approves Upgrade 20 with move to Super Root Dispute Games
- —The vote on Upgrade 20 was completed on September 16
- —The mainnet upgrade is scheduled for September 24 after a 7-day test
- —Permissioned networks move to game type 5, permissionless to game type 9
- —op-challenger and op-dispute-mon require Super Root support before the switch
Why it matters: The transition lays the groundwork for cross-chain Superchain interoperability without needing to change the security layer again.
