According to Wu, Vitalik recently published an article discussing the dispute over Bitcoin block size. "The Battle of Block Capacity" supports small blocks and emphasizes the convenience of running nodes, while "Hijacking Bitcoin" supports large blocks and pays more attention to low transaction fees. This difference in belief is the key to the debate. Vitalik supports large blocks in a macro sense, but prefers small blocks in specific details. He believes that the block size dispute is actually a tragedy involving cryptocurrency, companies, and national politics. The ultimate solution to this problem is not conflict or compromise, but through new technologies, to find a brand new way for both sides to get more of what they want.
