比特币现金（BCH）的故事要比创建另一个加密货币要深得多

比特币现金是由比特币网络中的硬叉创建的。比特币现金网络比比特币更大的块大小

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.

比特币现金（BCH）的故事要比创造另一种加密货币要深得多。它实际上是比特币权力下放的最激烈的测试之一。

What is Bitcoin Cash Summary

什么是比特币现金摘要

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).

比特币现金是由比特币网络中的硬叉创建的。比特币现金网络比比特币（目前为32MB，而不是比特币的1MB）支持更大的块大小。

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

后来，由于如何进行开发方面的差异，比特币现金分配给比特币SV。

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

简而言之，那是比特币现金。如果您想进行更详细的评论，请继续阅读。这是我要介绍的：

Hard Forks Explained

坚硬的叉子解释了

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.

许多人通常从比特币或加密货币开始时，当他们发现不仅有一种“类型”比特币时会感到困惑。例如，比特币现金，比特币黄金和比特币钻石都是原始比特币的叉子。

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

叉子可以描述为原始硬币的替代版本。叉子有两种类型：软叉和硬叉。

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.

软叉 - 与原始版本和硬币的替代版本都很好的版本，因此，作为用户，您可以选择要运行的版本而无需担心。

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 - 与原始版本不佳。这意味着您需要选择是否更新软件以运行替代版本或坚持原始版本。

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.

换句话说，使用硬叉，如果替代方案不被100％的用户接受，那么网络中将发生某种拆分，并且将出现新硬币。一种与原始相似但不一样的。

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

实际上，比特币现金和其他比特币版本是对比特币协议的建议更新的结果，该计划并非所有人都同意。

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，发生的事情是，创建了由原始比特币的替代版本或硬叉，并存在新硬币。

The Bitcoin Block Size Debate

比特币大小辩论

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

因此，现在我们知道比特币现金实际上是比特币的坚硬分叉，但是为什么会创建它？

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.

要回答这个问题，我们需要暂停一秒钟，然后回去几年，讨论比特币代码中最具争议的主题之一 - 块大小和可伸缩性问题。

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.

比特币交易不会立即确认。为了将交易视为确认的交易，必须将其作为比特币分类帐（称为区块链）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分钟添加一个新的交易块。

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.

与任何类型的数字数据类似，将比特币交易添加到一个块需要存储空间，每个交易块的最大容量为1 MB。当您考虑平均比特币交易规模时，您会发现一个块可以容纳约2700笔交易。

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分钟2700次交易意味着每秒4.6次交易，这并不多。进行比较，签证可以确认每秒1,700笔交易。

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.

这意味着，当很多人想在价格集会期间发送比特币时，交易被卡在孟买内部很长的队列中，等待进入块并得到确认。

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.

当然，如果您想跳出队列，比特币可以让您支付更高的交易费用，但这可能会导致费用达到荒谬的水平，因为越来越多的人试图通过交易“削减界限”。

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.

如果您要建造比特币成为全球付款方式，这不是您想发生的事情。由于这个可扩展性问题，出现了两个不同的营地。

Big Blocks Proponents

大块支持者

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.

第一个营地是“大街区”营地。该营地由中国矿业巨头比特曼（Bitmain）和罗杰·韦尔（Roger Ver）领导，后者是一个早期的比特币投资者，当比特币刚刚获得初步采用时，他参与了许多初创企业。

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担心比特币的可伸缩性问题会阻止其成为比特币的发明家Satoshi Nakamoto最初打算的东西 - 同行支付系统。

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.

有了如此长的确认时间和高费用，人们不会在日常交易中使用比特币，而是将其视为价值存储，例如黄金。

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.

这个营地的支持者提出了一个非常简单的解决方案 - 让我们增加块大小。如果我们将比特币的块大小增加到8MB，我们将能够确认每秒交易数量的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

这将减少网络的现有拥塞，将来，我们将根据需要增加块大小
