Hey Alex, long time no see. Happy New Year! First, congratulations to your success so far. From hackathon to zkSync payment to zkEVM to now ZK Stack, it has been a long way. Excited to see that you responded positively regarding [my previous concern regarding the significant cost of evaluating ZK Stack](https://forum.celo.org/t/matter-labs-proposal-for-celo-to-join-zk-nation-and-become-an-eth-l2-using-zk-stack/6629/7) and offered a $2.7M financial support. One follow-up question on this: are there any strings attached to this grant? If so, can you elaborate on details? One more question: Is ZK stack designed to easily switch the decentralized sequencer with another solution? As I replied in ARB’s proposal, [Celo has a battle-tested consensus layer and well positioned to transform it to become a decentralized sequencer](https://forum.celo.org/t/proposal-for-celo-to-migrate-to-ethereum-l2-leveraging-the-arbitrum-orbit-l2-sdk/7059/3). It will make more sense for CEL2 to use Celo’s own decentralized sequencer. In addition, my interpretation of the criteria - **Ongoing role for Celo node operator community** , is that existing Celo validators will perform new roles as L2 sequencers, validators, or DA providers, **but use CELO token to secure these networks**. --- _[View the full topic](https://forum.celo.org/t/applying-the-cel2-selection-framework-to-the-zk-stack-zksync/7178)._
