第三层网络：以太坊的未来是福还是祸？

在现有第 2 层 (L2) 协议之上出现第 3 层 (L3) 网络在以太坊社区内引发了争议。虽然有些人认为 L3 提供了专门的功能并促进了扩展，但其他人则认为它们降低了以太坊的价值并损害了其安全性。 Polygon Labs 首席执行官 Marc Boiron 对 L3 表示怀疑，认为它们将价值从以太坊转移到底层的 L2 上，从而损害了生态系统。

Layer-3 Networks: A Threat to Ethereum's Value or a Catalyst for Innovation?

第三层网络：对以太坊价值的威胁还是创新的催化剂？

The Ethereum ecosystem is undergoing a transformation, with the emergence of layer-3 (L3) networks sparking a heated debate within the cryptocurrency community. These innovative solutions, built atop layer-2 (L2) networks, have raised questions about their impact on Ethereum's value and the future of blockchain scaling.

以太坊生态系统正在经历变革，第三层 (L3) 网络的出现引发了加密货币社区的激烈争论。这些构建在第 2 层 (L2) 网络之上的创新解决方案引发了人们对其对以太坊价值和区块链扩展未来影响的质疑。

Polygon Labs CEO's Controversial Stance

Polygon Labs 首席执行官的争议立场

Marc Boiron, CEO of Polygon Labs, a leading L2 scaling network, has expressed his disapproval of L3 networks. In a recent blog post, he argued that L3s "exist only to take value away from Ethereum and onto the L2s on which the L3s are built." Boiron claims that L3s are unnecessary for scaling existing networks and that they could compromise Ethereum's security and overall value.

领先的 L2 扩展网络 Polygon Labs 的首席执行官 Marc Boiron 表达了他对 L3 网络的不满。在最近的一篇博客文章中，他认为 L3“存在只是为了将价值从以太坊转移到构建 L3 的 L2 上”。 Boiron 声称 L3 对于扩展现有网络来说是不必要的，并且它们可能会损害以太坊的安全性和整体价值。

"I'll say the quiet part out loud: L3s exist only to take value away from Ethereum and onto the L2s on which the L3s are built," wrote Boiron. "You do not need L3s to scale."

“我要大声说出安静的部分：L3 的存在只是为了将价值从以太坊转移到构建 L3 的 L2 上，”Boiron 写道。 “你不需要 L3 来扩展。”

Boiron's comments have ignited a fiery debate, with proponents and detractors alike weighing in on the merits of L3 networks.

Boiron 的言论引发了一场激烈的争论，支持者和反对者都对 L3 网络的优点进行了权衡。

The Benefits of L3 Networks

L3 网络的好处

Supporters of L3 networks argue that they offer several advantages that L2s cannot provide. Peter Haymond, senior partnership manager at Offchain Labs, highlighted the cost-effectiveness of native bridging from L2 rather than L1, the affordability of proving on-chain, the use of custom gas tokens, and specialized state transition functions as key benefits of L3s.

L3 网络的支持者认为，它们提供了 L2 无法提供的多项优势。 Offchain Labs 的高级合作伙伴经理 Peter Haymond 强调了 L2 而不是 L1 的本机桥接的成本效益、链上证明的可负担性、自定义 Gas 代币的使用以及专门的状态转换功能，这些都是 L3 的主要优势。

Arbitrum Foundation researcher Patrick McCorry expressed surprise at Boiron's viewpoint, emphasizing the significant advantages offered by L3s, particularly their ability to enable L2s to evolve into settlement layers. This, McCorry argues, reduces the cost of executing bridges and allows Ethereum to serve as a global ordering service and final arbiter of settlements.

Arbitrum 基金会研究员 Patrick McCorry 对 Boiron 的观点表示惊讶，强调 L3 提供的显着优势，特别是它们使 L2 演变成结算层的能力。麦考里认为，这降低了执行桥梁的成本，并使以太坊能够充当全球订购服务和结算的最终仲裁者。

Vitalik Buterin's Perspective

Vitalik Buterin 的观点

The debate over L3 networks was initially sparked by Ethereum co-founder Vitalik Buterin in late 2022. Buterin acknowledged the potential value of L3s, but emphasized that they should offer unique functions not provided by L2s.

关于 L3 网络的争论最初是由以太坊联合创始人 Vitalik Buterin 在 2022 年底引发的。Buterin 承认 L3 的潜在价值，但强调它们应该提供 L2 不提供的独特功能。

"A third layer on the blockchain would only be justified if it introduced unique functions not provided by layer-2s," Buterin wrote.

Buterin 写道：“区块链上的第三层只有引入第 2 层未提供的独特功能才是合理的。”

The Future of L3 Networks

L3 网络的未来

Despite the debate and differing opinions, the L3 ecosystem continues to grow and evolve. Orbs, zkSync Hyperchains, Xai, and Degen Chain are among the leading players in this emerging space. However, the sector remains relatively small, with only four L3 tokens currently listed on CoinGecko.

尽管存在争论和不同意见，L3 生态系统仍在不断发展和发展。 Orbs、zkSync Hyperchains、Xai 和 Degen Chain 是这个新兴领域的领先参与者。然而，该行业仍然相对较小，目前只有四种 L3 代币在 CoinGecko 上上市。

Whether or not L3 networks will ultimately detract from Ethereum's value remains to be seen. The ongoing debate highlights the dynamic and ever-evolving nature of the blockchain industry. As the technology matures and new applications are developed, the role of L3 networks within the Ethereum ecosystem will undoubtedly continue to be a topic of discussion and debate.

L3 网络最终是否会降低以太坊的价值还有待观察。持续不断的争论凸显了区块链行业的动态和不断发展的本质。随着技术的成熟和新应用的开发，L3网络在以太坊生态系统中的作用无疑将继续成为讨论和争论的话题。
