第 2 層 (L2) 解決方案：比特幣的新時代

第 2 層解決方案曾經被認為是一個晦澀的技術概念，如今卻被定位為比特幣可擴展性的關鍵。

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 層 (L2) 解決方案在加密貨幣行業中快速採用，為比特幣等較慢的區塊鏈提供了一種提高速度並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 預測，到 2024 年，比特幣 L2 專案將增加七倍，吸引創紀錄的投資。

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.

根據他們的分析，到 2030 年，這些基礎設施可能會出現 470 億美元的大規模遷移。

Why are Layer 2 solutions so attractive?

為什麼第 2 層解決方案如此有吸引力？

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

Layer 2 解決方案一度被認為是一個晦澀的技術概念，但現在被定位為比特幣可擴展性的關鍵。

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.

他們為主網的歷史限制提供了解決方案：速度慢和成本高。但它們的崛起並不僅限於簡單的技術問題。

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，經濟背景扮演關鍵角色。 2024 年，整個加密產業 44% 的專注於 Layer 2 的創投基金被比特幣 L2 專案吸引。

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.

這種動態可以透過逐漸認識來解釋：比特幣提供的機會遠遠超出其「數位黃金」的地位。透過 Layer 2 產生回報的能力吸引了新型投資者。

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 技術的多樣性也促進了它們的流行。例如，側鏈在 2024 年吸引了 1.05 億美元，而 Rollups 則吸引了 6,300 萬美元。這些工具提供各種互補的功能，對企業和獨立開發人員都有吸引力。

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.

最後，持續的創新有利於比特幣。 2023 年出現的 BRC-20 代幣為前所未有的應用鋪平了道路。這些創新甚至促使先前持懷疑態度的投資者重新考慮他們的立場。結果：Layer 2 不再是利基市場，而是一個機車。

A decade of promises

十年的承諾

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，潛在市場總額預計將達到 470 億美元，Layer 2 正成為比特幣的策略性成長槓桿。然而，並非所有事情都已提前解決。雖然目前有 75 個項目正在建立這個生態系統，但 Galaxy Research 預測，到本十年末，只有三到五個參與者將成為領導者。

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.

這種激烈的競爭雖然有風險，但卻推動了創新。隨著生態系統的成熟，比特幣持有者將其資產鎖定在這些網路上的興趣只會增加。

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

如果比特幣如一些分析師預測的那樣達到 10 萬美元，那麼 Layer 2 的承諾很可能成為不可否認的現實。

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?

總而言之，Layer 2 正在改變比特幣。它們為其賦予了新的生命力、前所未有的可擴展性，最重要的是，它具有吸引新用戶的能力。它們不僅是技術調整，更是第一種加密貨幣的未來。如果當大規模清算將比特幣推至 97k 時，最好的時刻尚未到來怎麼辦？
