According to Mars Finance, CZ issued a statement to discuss the choice between AI projects between L1 and L2. He pointed out that the core of AI projects is to use blockchain to optimize the AI ​​economy rather than build a better public chain. L1 provides higher sovereignty and decentralization, but requires running complete nodes and validators, which are work-intensive and may form an isolated ecosystem; L2 saves the complexity of maintaining infrastructure and can use existing DEX, derivatives markets and other tools to lose almost no value to L1 (such as ETH). CZ believes that L1 and L2 have their own advantages and disadvantages, and the key lies in how to provide a better economic and application environment for AI projects.
