According to online reports, Solana co-founder toly said in a reply to netizens in X: "ZK is slower than traditional computing. So Solana is always faster than ZK because there is no religious reason to limit full-node capacity." Alex Gluchowski, CEO of ZKsync developer Matter Labs, responded: "ZK is always faster than Solana because it is protected by mathematics rather than validators, which means that one or a few validators (for redundancy) are enough, and you don't have to wait for thousands of nodes to reach consensus."
