Like @jessepollak said, I think this is a good v0 proposal that would benefit the entire rollup ecosystem. As more and more assets are held in rollups, it’s becoming increasingly important for users to have a clear understanding of the security model of the system they’re using. A standardized security framework is going to be a key part of this.
My primary feedback is that there are “nice to haves” that aren’t necessarily covered by a framework like this that can have a real impact on the overall security of the network. For example, the ability to easily preview and upgrade and understand its implications can be the deciding factor between a bug slipping through and a secure system. Of course, that’s not strictly required but, like I said, it’s a nice to have that has a real impact.
IMO a good v1 version of a framework like this looks sort of like a tech/skill tree. You have specific key requirements that are necessary for advancement to the next stage but you can also unlock bonus items that give you “points” but aren’t requirements for advancement. You might be able to extend this model by assigning points and required features such that the requirement for advancement is X number of points and some set of necessary features. Assigning points also reflects the relative value of different features (especially non-critical features) and can help teams prioritize their work.
I’d really like to see comments on this proposal from other rollup teams so we can start to build consensus. Generally, the sooner the better with a framework like this. Rollup risk is only increasing and this is a critical first step in pushing rollups towards real security.
