比特幣現金的誕生：創新與進化之旅

加密貨幣的世界通常是由創新和進化來定義的。這趟旅程的關鍵一章是比特幣現金（BCH）的誕生

The world of cryptocurrencies is constantly evolving, and one pivotal moment in this journey was the birth of Bitcoin Cash (BCH). This digital currency emerged to address the rising congestion in Bitcoin's network, sparking a debate that would forever change the landscape of decentralized finance.

加密貨幣的世界不斷發展，這個過程中的一個關鍵時刻是比特幣現金（BCH）的誕生。這種數位貨幣的出現是為了解決比特幣網路日益擁擠的問題，引發了一場將永遠改變去中心化金融格局的爭論。

Bitcoin, the pioneering cryptocurrency, quickly gained massive popularity as it offered a decentralized alternative to traditional financial systems. However, as more users began transacting with Bitcoin, its network encountered a common pain point — high transaction fees and frustratingly slow confirmation times.

比特幣是一種開創性的加密貨幣，由於它提供了傳統金融系統的去中心化替代方案，因此迅速獲得了廣泛的歡迎。然而，隨著越來越多的用戶開始使用比特幣進行交易，其網路遇到了一個共同的痛點——高昂的交易費用和令人沮喪的緩慢確認時間。

These issues largely stemmed from Bitcoin's 1 MB block size limit, which dictated the total amount of transactions that could be processed every 10 minutes. As the volume of transactions increased exponentially, it became clear to some in the community that the original block size was no longer adequate for the network's growing user base.

這些問題很大程度上源於比特幣的 1 MB 區塊大小限制，該限制規定了每 10 分鐘可以處理的交易總量。隨著交易量呈指數級增長，社區中的一些人清楚地意識到，原始的區塊大小已不足以滿足網路不斷增長的用戶群。

This realization sparked a heated debate within the Bitcoin community, with two main camps forming around competing solutions. One group, led by Bitcoin creator Satoshi Nakamoto and several core developers, favored a more conservative approach, advocating for the implementation of off-chain scaling techniques such as the Lightning Network.

這一認識引發了比特幣社群內的激烈爭論，圍繞著相互競爭的解決方案形成了兩個主要陣營。由比特幣創造者中本聰和幾位核心開發人員領導的一個團體傾向於採取更保守的方法，主張實施閃電網路等鏈下擴容技術。

The other camp, spearheaded by influential figures like Roger Ver and Jihan Wu, prioritized on-chain scaling and pushed for an immediate increase in the block size. They argued that Nakamoto's original vision for Bitcoin was as a peer-to-peer electronic cash system, and that on-chain scaling was crucial to maintaining this vision.

另一個陣營由 Roger Ver 和吳忌寒等有影響力的人物帶頭，優先考慮鏈上擴容，並推動立即增加區塊大小。他們認為，中本聰對比特幣的最初願景是作為一個點對點的電子現金系統，而鏈上擴容對於維持這個願景至關重要。

This division of opinions culminated in a hard fork on August 1, 2017, leading to the creation of Bitcoin Cash. The new cryptocurrency inherited Bitcoin's transaction history up to the fork block but diverged from the main chain by increasing the block size to 8 MB. This change aimed to accommodate a significantly higher number of transactions per second.

這種意見分歧在 2017 年 8 月 1 日的硬分叉中達到頂峰，導致了比特幣現金的誕生。新的加密貨幣繼承了比特幣直到分叉區塊的交易歷史，但透過將區塊大小增加到 8 MB 與主鏈不同。這項變更旨在容納每秒顯著增加的交易數量。

With the larger block size, BCH transactions became faster and cheaper compared to BTC. However, the trade-off was a higher hardware requirement to participate in the BCH network, as larger blocks required more storage and computational power.

與 BTC 相比，隨著區塊大小的增大，BCH 交易變得更快、更便宜。然而，代價是參與 BCH 網路對硬體的要求更高，因為更大的區塊需要更多的儲存和運算能力。

This decision sparked contrasting reactions among the crypto community. Supporters of Bitcoin Cash praised it for prioritizing transaction efficiency and scalability, arguing that it remained faithful to Bitcoin's original design principles.

這項決定在加密貨幣社群中引發了截然不同的反應。比特幣現金的支持者稱讚它優先考慮交易效率和可擴展性，認為它仍然忠於比特幣的原始設計原則。

On the other hand, critics maintained that increasing the block size came at the cost of greater centralization. They argued that the larger block size would favor mining pools and large exchanges, as they possessed the necessary infrastructure to handle the increased block size and transaction volume.

另一方面，批評者認為，增加區塊大小是以更大的中心化為代價的。他們認為，較大的區塊大小將有利於礦池和大型交易所，因為它們擁有必要的基礎設施來處理增加的區塊大小和交易量。

This centralization concern stemmed from the fact that running a full Bitcoin node became more demanding with the increased block size. As a result, some believed that only a smaller group of entities would be able to actively participate in the network and contribute to the consensus process.

這種集中化擔憂源於這樣一個事實：隨著區塊大小的增加，運行完整的比特幣節點變得更加困難。因此，有些人認為只有一小部分實體能夠積極參與網路並為共識過程做出貢獻。

Despite the controversy surrounding its creation, Bitcoin Cash went on to carve out its space in the cryptocurrency ecosystem. It continues to offer users a fast, low-fee transaction experience, catering to those who prioritize speed and affordability in their digital currency transactions.

儘管圍繞其創建存在爭議，比特幣現金仍繼續在加密貨幣生態系統中開闢自己的空間。它繼續為用戶提供快速、低費用的交易體驗，迎合那些在數位貨幣交易中優先考慮速度和負擔能力的人。
