比特幣現金（BCH）：注重可擴展性的比特幣分叉

比特幣的快速崛起不僅帶來了全球關注，也帶來了成長的煩惱。隨著數百萬用戶加入網絡，比特幣面臨越來越多的問題

Bitcoin's rapid ascent not only brought global fanfare but also growing pains. As millions of users flocked to the network, Bitcoin faced mounting problems, including high transaction fees and slow confirmation times. This congestion sparked a heated debate among developers and miners, culminating in the creation of Bitcoin Cash (BCH) — a cryptocurrency designed to solve Bitcoin's scalability woes.

比特幣的快速崛起不僅帶來了全球的關注，也帶來了成長的煩惱。隨著數百萬用戶湧入網絡，比特幣面臨越來越多的問題，包括交易費用高和確認時間慢。這種擁塞引發了開發人員和礦工之間的激烈爭論，最終催生了比特幣現金（BCH）——一種旨在解決比特幣可擴展性問題的加密貨幣。

The Scalability Quandary

可擴展性的困境

Bitcoin was conceived to upend financial transactions by offering a decentralized alternative to legacy systems. However, the network's initial design limited each block to 1 MB of transaction data. While this size was adequate during Bitcoin's early days, it quickly became a bottleneck as adoption surged. Transaction backlogs piled up, fees soared, and confirmation times stretched, leaving users frustrated.

比特幣旨在透過提供傳統系統的去中心化替代方案來顛覆金融交易。然而，網路的初始設計將每個區塊的交易資料限制為 1 MB。雖然這個規模在比特幣早期已經足夠了，但隨著採用率的激增，它很快就成為了瓶頸。交易積壓堆積、費用飆漲、確認時間延長，讓用戶感到沮喪。

The community recognized that Bitcoin needed a way to scale efficiently. However, they were divided on the best approach.

社群認識到比特幣需要一種有效擴容的方法。然而，他們在最佳方法上存在分歧。

The Community Fork

社區分叉

Two main approaches emerged from the discussion:

討論中出現了兩種主要方法：

The philosophical divide between these two visions led to a historic decision—a hard fork in the Bitcoin network.

這兩種願景之間的哲學分歧導致了一個歷史性的決定——比特幣網路的硬分叉。

Enter Bitcoin Cash

On August 1, 2017, Bitcoin Cash was launched. By increasing the block size from Bitcoin's 1 MB to 8 MB, BCH could accommodate more transactions per block, offering users faster processing and lower fees. This increased block size was later expanded to 32 MB,大幅 boosting its transaction capacity.

2017 年 8 月 1 日，比特幣現金推出。透過將區塊大小從比特幣的 1 MB 增加到 8 MB，BCH 可以容納每個區塊的更多交易，為用戶提供更快的處理速度和更低的成本。增加的區塊大小後來擴展到 32 MB，大大提高了其交易能力。

Proponents of Bitcoin Cash touted it as a return to Bitcoin's original purpose: digital cash for everyday transactions. They viewed the larger block size as a pragmatic solution for enhancing scalability while maintaining decentralization.

比特幣現金的支持者將其吹捧為對比特幣最初目的的回歸：用於日常交易的數位現金。他們認為更大的區塊大小是一種實用的解決方案，可以在保持去中心化的同時增強可擴展性。

Critics, however, raised concerns about the potential for increased block size to lead to centralization. Larger blocks require more storage and computational resources, limiting the number of network participants who could run a full node.

然而，批評者對增加區塊大小可能導致中心化表示擔憂。較大的區塊需要更多的儲存和運算資源，從而限制了可以運行完整節點的網路參與者的數量。

Bitcoin Cash Today

Despite the differing perspectives, Bitcoin Cash has gone on to flourish as a high-speed, low-fee counterpart to Bitcoin. Its creation marked a pivotal moment in blockchain history, reflecting both the challenges and the innovation that define the cryptocurrency realm. The debate that gave birth to BCH highlights the continuous evolution of digital finance and the relentless quest for efficiency in a decentralized world.

儘管有不同的觀點，比特幣現金作為比特幣的高速、低費用的對應物繼續蓬勃發展。它的創建標誌著區塊鏈歷史上的關鍵時刻，反映了定義加密貨幣領域的挑戰和創新。催生 BCH 的論點凸顯了數位金融的不斷發展以及去中心化世界對效率的不懈追求。
