What are your thoughts on enhancing zk-Rollups with hardware-grade security? 

ZK proofs are already so robust, and adding Trusted Execution Environments as hardware-based 2FA for zk-Rollups could further boost their real-world security.

I read a blog post by Phala that spoke about an approach of using the Phala SGX-Prover, which integrates TEEs to boost both the security and performance of zk-Rollups. Their TEE-Proof system offers hardware-grade safety, minimal costs, and ensures high availability without disrupting existing zk-Rollup systems.

What do you think about using TEEs for zk-Rollups?
