I'm really happy we have one unambiguously stage 1 rollup (and a couple more very-close-to-stage-1 rollups) this year.

Real decentralization.

Let's get to ten stage 1 rollups, and some degree of sequencer decentralization, in the next year.

You can see them here:

In a stage 2 rollup, you would have to prove directly to the smart contract that there is a bug to activate the Security Council at all. One simple example of this is: if the rollup has two proof systems, and someone provides a proof of system 1 proving one root and system 2 proving a different root.

> The Security Council’s actions are not confined to on-chain provable bugs

Who determines what is a provable “bug” and what is a “feature”? If there’s subjectivity to this does this not degrade back down to arbitrary upgrading?
