Optimism Proposal Changes Upgrade Control Authority
An Optimism governance proposal requires at least 30 days' public notice before transferring upgrade control from the shared Security Council. This change would allow users to assess changes to the network's security model and could result in the chain ceasing to be a Standard Rollup if the transfer goes ahead. The Security Council would no longer retain the same practical ability to enforce the Charter's policies on that chain through upgrade authority.
