According to ChainCatcher, Vitalik Buterin tweeted that Layer 2 (L2) technology has finally become affordable, which is the key to popularizing decentralized finance (DeFi). As early as 2020, he proposed that low transaction fees are the basis for the success of the crypto industry, which has only recently become a reality.
Robert Sasu, a core engineer at MultiverseX, responded that L2 is currently only cheap in a centralized environment. Vitalik disagreed with this view and pointed out that Taiko is a decentralized rollup-based solution, indicating that the fees of decentralized L2s 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 can migrate to this architecture.
