**Ethereum founder Vitalik Buterin: Layer 2 technology is finally affordable! 🎉**

BlockBeats news, on September 16, Ethereum founder Vitalik Buterin posted on X (original Twitter) that Layer 2 (L2) technology has finally become affordable, which is the key to popularizing decentralized finance (DeFi). As early as 2020, Vitalik proposed that low transaction fees are the basis for the success of the crypto industry, which has only recently become a reality.

Vitalik's view has sparked widespread discussion. 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 L2 like Taiko have reached an affordable level. Sasu agreed, but added that rollup-based solutions are still a minority and hopes that more projects can migrate to this architecture.

**Breakthrough in L2 technology: the key to the popularization of DeFi**

Vitalik's views have undoubtedly injected a shot in the arm for the future of DeFi. Low transaction fees can not only attract more users to participate, but also promote the birth of more innovative projects. This is undoubtedly good news for those users who are deterred by high transaction fees.

**Debate on decentralization and centralization**

However, Sasu's response also reminds us that L2 technology still needs to find a balance between decentralization and centralization while achieving low fees. Although decentralized L2 solutions like Taiko have achieved some success, they are still a minority. In the future, more projects need to migrate to this architecture to truly realize the vision of decentralization.

**Summary**

In general, the advancement of L2 technology has brought new hope for the popularization of DeFi, but finding a balance between decentralization and centralization is still a challenge. I hope that more projects will adopt decentralized L2 solutions in the future, bringing more innovations and opportunities to the crypto industry.
