Vitalik Buterin tweeted that Layer 2 (L2) technology is finally becoming affordable, which is the key to popularizing decentralized finance (DeFi). As early as 2020, he proposed that low transaction fees are fundamental to 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 situation. Vitalik disagrees with this view and points out that Taiko is a decentralized based rollup 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.
