比特幣現金（BCH）的故事要比創建另一個加密貨幣要深得多

比特幣現金是由比特幣網絡中的硬叉創建的。比特幣現金網絡比比特幣更大的塊大小

The story of Bitcoin Cash (BCH) goes much deeper than just the creation of another cryptocurrency. It was actually one of the fiercest tests for Bitcoin’s decentralization.

比特幣現金（BCH）的故事要比創造另一種加密貨幣要深得多。它實際上是比特幣權力下放的最激烈的測試之一。

What is Bitcoin Cash Summary

什麼是比特幣現金摘要

Bitcoin Cash was created as a result of a hard fork in the Bitcoin network. The Bitcoin Cash network supports a larger block size than Bitcoin (currently 32mb as opposed to Bitcoin’s 1mb).

比特幣現金是由比特幣網絡中的硬叉創建的。比特幣現金網絡比比特幣（目前為32MB，而不是比特幣的1MB）支持更大的塊大小。

Later on, Bitcoin Cash forked into Bitcoin SV due to differences in how to carry on its developments.

後來，由於如何進行開發方面的差異，比特幣現金分配給比特幣SV。

That’s Bitcoin Cash in a nutshell. If you want a more detailed review keep on reading. Here’s what I’ll cover:

簡而言之，那是比特幣現金。如果您想進行更詳細的評論，請繼續閱讀。這是我要介紹的：

Hard Forks Explained

堅硬的叉子解釋了

A lot of people who are just starting out with Bitcoin or cryptocurrency in general, get confused when they see that there’s not just one “type” of Bitcoin. For example, Bitcoin Cash, Bitcoin Gold and Bitcoin Diamond are all forks of the original Bitcoin.

許多人通常從比特幣或加密貨幣開始時，當他們發現不僅有一種“類型”比特幣時會感到困惑。例如，比特幣現金，比特幣黃金和比特幣鑽石都是原始比特幣的叉子。

A fork can be described as an alternate version of an original coin. There are two types of forks: soft forks and hard forks.

叉子可以描述為原始硬幣的替代版本。叉子有兩種類型：軟叉和硬叉。

Soft forks – Versions that work well with both the original version and the alternate version of the coin, so as a user, you can choose which version to run without a lot of concern.

軟叉 - 與原始版本和硬幣的替代版本都很好的版本，因此，作為用戶，您可以選擇要運行的版本而無需擔心。

Hard forks – Don’t play well with the original version. This means that you need to choose whether to update your software to run the alternate version, or to stick with the original one.

硬叉 - 與原始版本不佳。這意味著您需要選擇是否更新軟件以運行替代版本或堅持原始版本。

In other words, with hard forks, if the alternative is not accepted by 100% of the users, then a sort of split will occur in the network and a new coin will emerge. One that is similar to the original but not identical.

換句話說，使用硬叉，如果替代方案不被100％的用戶接受，那麼網絡中將發生某種拆分，並且將出現新硬幣。一種與原始相似但不一樣的。

Bitcoin Cash and other Bitcoin versions are actually the results of suggested updates to the Bitcoin protocol that weren’t agreed to by everyone.

實際上，比特幣現金和其他比特幣版本是對比特幣協議的建議更新的結果，該計劃並非所有人都同意。

So what happened is that an alternate version, or a hard fork, stemming from the original Bitcoin was created and new coins came into existence.

因此，發生的事情是，創建了由原始比特幣的替代版本或硬叉，並存在新硬幣。

The Bitcoin Block Size Debate

比特幣大小辯論

So now we know that Bitcoin cash is actually a hard fork of Bitcoin, but why was it created?

因此，現在我們知道比特幣現金實際上是比特幣的堅硬分叉，但是為什麼會創建它？

To answer this question, we need to pause for a second and go back a few years to discuss one of the most controversial topics of Bitcoin’s code – the block size and scalability issue.

要回答這個問題，我們需要暫停一秒鐘，然後回去幾年，討論比特幣代碼中最具爭議的主題之一 - 塊大小和可伸縮性問題。

Bitcoin transactions don’t get confirmed instantly. In order for a transaction to be considered as confirmed it needs to be included as part of a block of transactions on the Bitcoin ledger, known as the blockchain.

比特幣交易不會立即確認。為了將交易視為確認的交易，必須將其作為比特幣分類帳（稱為區塊鏈）上交易的一部分。

A new block of transactions is added to the blockchain on average about every 10 minutes.

平均每10分鐘添加一個新的交易塊。

Similar to any type of digital data, adding Bitcoin transactions to a block requires storage space, and the maximum capacity for each block of transactions is 1 MB. When you consider the average Bitcoin transaction size, you’ll find that a block is able to hold about 2700 transactions.

與任何類型的數字數據類似，將比特幣交易添加到一個塊需要存儲空間，每個交易塊的最大容量為1 MB。當您考慮平均比特幣交易規模時，您會發現一個塊可以容納約2700筆交易。

2700 transactions every 10 minutes means 4.6 transactions a second, that’s not a lot. Visa, for comparison, can confirm 1,700 transactions per second.

每10分鐘2700次交易意味著每秒4.6次交易，這並不多。進行比較，簽證可以確認每秒1,700筆交易。

This means that when a lot of people want to send Bitcoin, during price rallies, for example, transactions get stuck in a very long queue inside the mempool, waiting to enter a block and get confirmed.

這意味著，當很多人想在價格集會期間發送比特幣時，交易被卡在孟買內部很長的隊列中，等待進入塊並得到確認。

Of course, Bitcoin allows you to pay a higher transaction fee if you want to jump the queue, but this might cause fees to reach ridiculous levels as more and more people try to “cut the line” with their transaction.

當然，如果您想跳出隊列，比特幣可以讓您支付更高的交易費用，但這可能會導致費用達到荒謬的水平，因為越來越多的人試圖通過交易“削減界限”。

This isn’t something you want to have happened if you’re building Bitcoin to become a global payment method. As a result of this scalability issue, two different camps emerged.

如果您要建造比特幣成為全球付款方式，這不是您想發生的事情。由於這個可擴展性問題，出現了兩個不同的營地。

Big Blocks Proponents

大塊支持者

The first camp was the “Big Blocks” camp. This camp was led by Chinese mining giant Bitmain and Roger Ver, an early Bitcoin investor who was involved with a number of startups when Bitcoin was just gaining initial adoption.

第一個營地是“大街區”營地。該營地由中國礦業巨頭比特曼（Bitmain）和羅傑·韋爾（Roger Ver）領導，後者是一個早期的比特幣投資者，當比特幣剛剛獲得初步採用時，他參與了許多初創企業。

Big blockers were afraid that Bitcoin’s scalability issue would prevent it from becoming what Satoshi Nakamoto, Bitcoin’s inventor, initially intended – a peer to peer payment system.

Big Blasser擔心比特幣的可伸縮性問題會阻止其成為比特幣的發明家Satoshi Nakamoto最初打算的東西 - 同行支付系統。

With such long confirmation times and high fees, people wouldn’t use Bitcoin for day to day transactions and would instead treat it as a store of value – like gold.

有瞭如此長的確認時間和高費用，人們不會在日常交易中使用比特幣，而是將其視為價值存儲，例如黃金。

The supporters of this camp suggested a very simple solution – Let’s increase the block size. If we increase Bitcoin’s block size to 8mb, we’ll be able to confirm as many as 8 times the number of transactions per second.

這個營地的支持者提出了一個非常簡單的解決方案 - 讓我們增加塊大小。如果我們將比特幣的塊大小增加到8MB，我們將能夠確認每秒交易數量的8倍。

This will reduce the existing congestion of the network, and in the future, we’ll increase the block size as much as needed

這將減少網絡的現有擁塞，將來，我們將根據需要增加塊大小
