According to BlockBeats on September 16th, Vitalik Buterin, the founder of Ethereum, stated in a post on X that Layer 2 (L2) technology has finally become affordable, which is key to the popularization of Decentralized Finance (DeFi). He proposed as early as 2020 that low transaction fees are the foundation for the success of the encryption industry, and this has only recently become a reality. Robert Sasu, the core engineer of MultiverseX, responded that L2 is currently only affordable in centralized situations. Vitalik disagrees with this view, pointing out that Taiko is a Decentralization-based rollup solution, indicating that the fees for Decentralization L2 solutions like Taiko have reached an affordable level. Sasu agreed, but added that rollup-based solutions are still in the minority, and hopes that more projects will migrate to this architecture.
