第 2 层 (L2) 解决方案：比特币的新时代

第 2 层解决方案曾经被认为是一个晦涩的技术概念，如今却被定位为比特币可扩展性的关键。

Layer 2 (L2) solutions are experiencing rapid adoption in the cryptocurrency industry, offering a way to enhance speed and reduce transaction costs on slower blockchains like Bitcoin.

第 2 层 (L2) 解决方案正在加密货币行业中得到快速采用，为比特币等较慢的区块链提供了一种提高速度并降低交易成本的方法。

Galaxy Research predicts a sevenfold increase in L2 projects for Bitcoin by 2024, attracting record investments.

Galaxy Research 预测，到 2024 年，比特币 L2 项目将增加七倍，吸引创纪录的投资。

According to their analysis, these infrastructures could witness a massive migration of $47 billion by 2030. This development could redefine Bitcoin’s role in the crypto ecosystem.

根据他们的分析，到 2030 年，这些基础设施可能会出现 470 亿美元的大规模迁移。这一发展可能会重新定义比特币在加密生态系统中的角色。

Why are Layer 2 solutions so attractive?

为什么第 2 层解决方案如此有吸引力？

Once perceived as an obscure technical concept, Layer 2 solutions are now positioned as the key to Bitcoin’s scalability.

Layer 2 解决方案一度被认为是一个晦涩的技术概念，但现在被定位为比特币可扩展性的关键。

They offer solutions to the historical limitations of the main network: slowness and high costs. But their rise is not limited to a simple technical question.

他们为主网的历史局限性提供了解决方案：速度慢和成本高。但它们的崛起并不仅仅局限于简单的技术问题。

First of all, the economic context plays a key role. In 2024, 44% of venture capital funds dedicated to Layer 2 across the crypto industry were captured by Bitcoin L2 projects.

首先，经济背景起着关键作用。 2024 年，整个加密行业 44% 的专注于 Layer 2 的风险投资基金被比特币 L2 项目吸引。

This dynamic is explained by a gradual awareness: the opportunities offered by Bitcoin go far beyond its status as “digital gold.” The ability to generate returns through Layer 2 attracts a new type of investor.

这种动态可以通过逐渐认识来解释：比特币提供的机会远远超出其“数字黄金”的地位。通过 Layer 2 产生回报的能力吸引了新型投资者。

Moreover, the diversity of L2 technologies contributes to their popularity. Sidechains, for example, captured $105 million in 2024, while rollups attracted $63 million. These tools offer various and complementary functionalities, appealing to both businesses and independent developers.

此外，L2 技术的多样性也促进了它们的流行。例如，侧链在 2024 年吸引了 1.05 亿美元，而 Rollups 则吸引了 6300 万美元。这些工具提供各种互补的功能，对企业和独立开发人员都有吸引力。

Finally, constant innovation works in favor of Bitcoin. BRC-20 tokens, which emerged in 2023, paved the way for unprecedented applications. These innovations have even prompted previously skeptical investors to reconsider their position. The result: Layer 2 is no longer a niche but a locomotive.

最后，持续的创新有利于比特币。 2023 年出现的 BRC-20 代币为前所未有的应用铺平了道路。这些创新甚至促使之前持怀疑态度的投资者重新考虑他们的立场。结果：Layer 2 不再是一个利基市场，而是一个机车。

A decade of promises

十年的承诺

With a total addressable market estimated at 47 billion dollars by 2030, Layer 2s are emerging as a strategic growth lever for Bitcoin. However, not everything is settled in advance. While 75 projects are currently building this ecosystem, Galaxy Research forecasts that only three to five actors will emerge as leaders by the end of the decade.

到 2030 年，潜在市场总额预计将达到 470 亿美元，Layer 2 正在成为比特币的战略增长杠杆。然而，并非所有事情都已提前解决。虽然目前有 75 个项目正在构建这个生态系统，但 Galaxy Research 预测，到本十年末，只有三到五个参与者将成为领导者。

This fierce competition, although risky, drives innovation. As the ecosystem matures, the interest of BTC holders in locking their assets on these networks will only increase.

这种激烈的竞争虽然有风险，但却推动了创新。随着生态系统的成熟，比特币持有者将其资产锁定在这些网络上的兴趣只会增加。

And if Bitcoin reaches 100,000 dollars, as some analysts predict, the promise of Layer 2s could well become an undeniable reality.

如果比特币如一些分析师预测的那样达到 10 万美元，那么 Layer 2 的承诺很可能成为不可否认的现实。

In summary, Layer 2s are transforming Bitcoin. They provide it with a new lease on life, unprecedented scalability, and above all, the ability to attract new users. More than just a technical adjustment, they are the future of the first cryptocurrency. And what if the best was yet to come while mass liquidations push Bitcoin to 97k?

总而言之，Layer 2 正在改变比特币。它们为其赋予了新的生命力、前所未有的可扩展性，最重要的是，它具有吸引新用户的能力。它们不仅仅是技术调整，更是第一种加密货币的未来。如果当大规模清算将比特币推至 97k 时，最好的时刻尚未到来怎么办？
