Vitalik: ZK-VMs Not Implementing Privacy Because Current Client Provers Are Not Fast Enough

Vitalik, co-founder of Ethernet, replied on social media platforms about the irony that the only use case not implemented in ZK-VM is privacy. The discussion stated that the explanation is actually quite simple: the privacy use case requires client-side generation of proofs, but the current client-side provers are not fast enough to handle complex tasks other than Merkle branching.
