Wu said that Solana co-founder Toly responded to a netizen by stating: "ZK is slower than traditional computing. So Solana is always faster than ZK because there are no religious reasons limiting the capacity of full nodes." In response, Alex Gluchowski, CEO of ZKsync developer Matter Labs, stated: "ZK is always faster than Solana because it is protected by mathematics rather than validators, which means one or a few validators (for redundancy) are sufficient, and you do not need to wait for thousands of nodes to reach consensus."
