Are you convinced that all Ethereum research is a scam? Offer me your sharpest criticism of ZK Sync. This construct here is phenomenal. From what I can tell, it is what sidechains were supposed to be, but better: offchain, trust-minimized, scalable, final.....
I actually think Ethereum should scrap sharding and focus on these types of solutions instead. Sharding is a hot mess. This thing is clean, elegant. Less confusing to reason about. I even think it can help scale bitcoin, I look forward to paying with tBTC-like things in ZK Sync.
It's bleeding-edge cryptography that enables this thing, and it still sits on Ethereum and inherits its issues, so those are reasons to be bearish on this, I guess. But can you come up with any other criticism? This is neat regardless. You could build it on any expressive chain.
