Thank you so much for the answer. A follow-up if you have time: Is there a path for zero-knowledge proof crypto to be regulated in a way that advances the industry?

Zk proofs are a really cool technology that still don’t have many big practical use cases yet imo. Zcash and Starknet would be the two but hope to find more at early stage
