区块链是比特币的一个重要概念，是利用块链式数据结构来验证与存储数据；利用分布式节点共识算法，来生成和更新数据；利用密码学的方式，保证数据传输和访问的安全；利用由自动化脚本代码组成的智能合约，来编程和操作数据的一种全新的分布式基础架构与计算方式。
The
它本质上是一个去中介化的数据库，同时作为比特币的底层技术，它还具备分布式数据存储、点对点传输、共识机制、加密算法等计算机技术的新型应用模式。
It is essentially a deintermediated database and, as a bottom technology for bitcoin, it also has new applications for distributed data storage, point-to-point transmission, consensus mechanisms, encryption algorithms, etc.
通过这种应用模式，区块链技术可以实现如下三个方面的功能：第一，保证链上数据不可篡改、不可伪造，提高数据的公信力和可信性；第二，实现交易的追溯,做到溯源监管和责任追踪；第三，智能合约可以基于契约自动执行，从而提高工作效率，降低运营成本。
Through this application model, block chain technology can achieve the following three functions: first, to enhance the credibility and credibility of data by ensuring that data on the chain are inflexible and non-false; secondly, to make transactions retroactive, with retroactive regulation and accountability tracking; and thirdly, to make smart contracts self-executing on the basis of contracts, thereby increasing efficiency and reducing operating costs.
回答这个问题的关键就是：先别管区块链是什么。
The key to answering this question is what the chain of blocks is.
很多人搞不懂区块链是什么就是因为上来就死抠“区块链是什么?”这个概念，然后被各种“区块”、“挖矿”、“去中心化”、“双花攻击”、“拜占庭将军问题”等等概念搞晕了。
Many people don't understand what a block chain is because it comes up and dies; what a block chain is? & & & & & & & ; & & & & & ; & & & & & Quo; & & & & & & & ; & & & & & & & ; & & & & & & & & & & & ; & & & & & & & & ; & & & & & & ; & & & & & & & & & ; & ; & & ; & & & & ; & & & & & & ; ; & & ; & & ; & & & ; & & & ; & & & & & ; & & & ; & & & & & & & & & & & & & & & & & & & ; ; & & & ; ; etc. ; etc ; etc.
就比如说我问你“手机是什么?”
Let's say I'm asking you & ldquao; what's a cell phone? & rdquao;
你先别往下看，你先想一想。定义一下“手机”。
Don't look down, think about it. Define & ldquao; mobile & rdquao;
你给出来的答案一定不是“可以在较广范围内使用的便携式电话终端”(取自百度百科)。这种定义我读都读不通畅。
The answer you give must not be & ldquo; it can be used in a wider range of portable telephone terminals & & rdquo (from encyclopedia). I can't even read that definition.
你会说：手机是用来打电话的，发微信的，刷抖音的，看朋友圈的。
You will say, "The cell phone is used to make phone calls, send e-mails, shivering, and watch the circle of friends."
同理，我们先不要纠结区块链的技术原理是什么，先问“区块链是用来干嘛的呢?”
By the same token, let's not dwell on the technical principles of the block chain, but ask & ldquo; what is the block chain for? & rdquao;
区块链是用来共同记录公共数据的，或者更狭义的说，用来记账的。
The
你说记账用电脑自己记就可以啊，为什么要区块链记呢?
You said you could just write the books on your own. Why do you have to write the chains?
因为你自己记的账别人不信。你谁啊?凭什么你记的别人就信?
Because you keep your own books and others don't believe. Who are you? Why do you keep your books and others believe?
比如，你在你的电脑里记了张三欠你1万块钱，张三说我电脑里还记了你欠我100万呢。那怎么办?
For example, you wrote down $10,000 in your computer and $10,000 in your computer and $1 million in my computer. What should I do?
以前这么解决：找一个公证人，你俩的账都记在公证人这里，出现纠纷以公证人的账本为准。比如银行就是干这个的。你俩的钱都存他那里，转账、借款都有记录。
This was the case before: finding a notary, you both keep your books with the notary, and there is a dispute with the notary's books. That's what banks do. You keep your money with him, you make transfers, you borrow loans.
区块链这么解决：你在自己的电脑里记账的时候，张三也在自己电脑里记一下同样的数据，记好之后，你俩互相检查一下，都认可了，这账就算正式记下了。中间不需要第三方或者所谓“权威机构”、“认证机构”的参与。
This is how the
大家共同记账的方式，也被称为“分布式”或“去中心化”，因为人人都记账，且账本的准确性由程式算法决定，而非某个权威机构。
You are also called &ldquao; distributed &rdquao; or &ldquao; decentralised & rdquao; because everyone is accounted for and the accuracy of the books is determined by the algorithm rather than by an authority.
这就是区块链，核心讲完了，区块链就这么简单，一个共同记账的账本。
This is the block chain. The core is finished. The block chain is as simple as that.
当然，区块链在实际应用中，参与人数可多可少，也会应用在包括数字金融、物联网、数字资产等等多个领域。比如应用在游戏领域就是大家一起记录游戏道具的所有权、道具属性等等。
Of course, block chains can be applied in a variety of ways, including digital finance, material networking, digital assets, and so on. For example, in the field of games they are used together to record the ownership, prop properties, and so on.
比特币，就是区块链在数字金融和数字货币领域最大的应用。
Bitcoin is the largest application of block chains in the fields of digital finance and digital money.
你说：啊?就这么简单吗?是的，就这么简单。
Say, ‘Ah, is it that simple?’ Yes, it is that simple.
剩下的都是技术怎么实现的问题，你不需要了解。就像你只要知道4G比3G快就行了，不需要知道4G是什么原理一样。只会把自己搞晕。
The rest is about how technology works, and you don't need to understand. Just like you need to know that 4G is faster than 3G, you don't need to know what 4G is. You just get dizzy.
现在要记账的不仅仅有你和张三了，还有李四王五赵六吴七以及他们数以百万计的子子孙孙们。几百万上千万个人要一起记账。
Now it's not just you and Zhang San, but Lee and his sons and grandchildren. Millions and millions of people need to be accounted for together.
怎么记?和前面一样，每转一笔账，所有人的电脑都记录一遍，然后相互检查，保证几百万台电脑的账都一模一样，这账就算正式记下了。
How? Like the previous one, every transfer, everyone's computer records it, and then checks each other to make sure that millions of computers are accounted for exactly the same, which is officially recorded.
这就是比特币，核心讲完了，比特币就这么简单。几百万台电脑一起记一本账，本本都一样，账上记录了每个人有多少钱(比特币)。
That's the bitcoin, that's the core, that's it. Millions of computers take one account together, this book is the same, and how much money is on the account for everyone.
剩下的都是技术怎么实现的问题。怎么实现的也不需要具体了解，你只要知道，比特币网络运行了10年，没出什么大问题就好了。
The rest is the question of how technology works. It doesn't need to be specific. You just know, the Bitcoin network has been running for 10 years, so there's no big problem.
你会说，按你这么说，比特币就记个账而已，为什么这么值钱啊?
You'd say, like you said, that bitcoin was just a bill. Why is it so valuable?
因为，金融世界本就只是一个巨大的账本啊。
Because the financial world was just a huge book of accounts.
你仔细想想，你的存款、你的股票、你的基金，都只是别人账本里的一串数字。
Think about it. Your savings, your shares, your funds are just a bunch of numbers in someone else's books.
不同的是，这支记账的笔，在谁的手里。
The difference is, the pen in the account is in whose hand.
稍微扯远一点，目前中美在区块链金融发力狂飙、军备竞赛的真正原因，就是要拿下给全世界记账的这支笔。这个我们后面详细解释。
A little further, the real reason why China and the United States are in the financial spiral of the block chain and the arms race is to take down the pen that accounts for the world. This is what we explained later.
你把钱存银行，这支记账的笔，就在银行手里。
You keep the money in the bank, this pen is in the bank's hand.
你可以深想一下，如果哪天，银行的系统出问题了，你账户里的钱余额变成了0，你怎么证明你账户里曾经有过那三万八千六?
You can think about it. If there's something wrong with the bank's system, the balance in your account turns zero, how do you prove that there were 386,000 in your account?
或者如果哪天，被人诬陷，所有银行账户被冻结，你该怎么办?明明是属于你的钱，如果不存进银行就不可能被冻结。现在存进去了反而就不再属于你的了。这种设定是不是很奇怪?
Or what would you do if, one day, all the bank accounts were framed and frozen? If it was your money, it wouldn't have been frozen if it had not been deposited in the bank. And now it's not yours. Isn't that odd?
当然，这种事情，是不会发生在法制健全、科技发达的我国的。不过在银行随时可能倒闭，本地货币随时可能一文不值的一些贫穷落后国家呢?
Of course, this is not going to happen in a country where the rule of law is strong and science and technology is advanced. But what about some poor and backward countries whose local currency is not worth anything at any time?
区块链可以如何改变这种情况呢?
How can the 如果这笔账是在运行正常的区块链上记录的，那么当银行说自己的电脑坏了查不到你的存款记录的时候，你可以告诉他，没关系，我的电脑里有记录，而且不仅仅我的电脑里有，另外的几百万台电脑里也有和我电脑一模一样的记录。 If this account is recorded on a well-functioning block chain, then when the bank says that it can't trace your deposit record, you can tell him that it's okay, that there's a record in my computer, not just in my computer, but in millions of computers, it's exactly the same as my computer. 同样，在正常运行的区块链上，银行也无法冻结你的账户。因为你的资产不再是只存在它电脑里的一串字符，而是在千万台电脑里都广泛被承认的。 Similarly, in a functional block chain, banks cannot freeze your accounts. Because your assets are no longer just a string of characters in its computer, but are widely recognized in tens of millions of computers. 同时，区块链具有极其顽强的生命力。比特币，之所以在被众多国家严令禁止的情况下还能够存活这么多年，并且价格越来越高，就是因为它太难被禁了。世界上数十万台记录着同一本比特币账本的计算机，分布在数十个国家的学校机房、普通民宅、深山老林、旷野深处。不管如何打击，只要世界上还有一台机器还在跑着比特币账本，它就不会真正死去。 At the same time, the chain of blocks is extremely tenacious. Bitcoin, which is still alive for so many years and has become more expensive because it is strictly forbidden by many countries, has hundreds of thousands of computers in the world that record the same bitcoin account, located in dozens of countries’ school rooms, common homes, deep mountain forests, and deep fields. 关于区块链是什么这个问题，到此就回答完毕了。下面是我关于中美未来在区块链金融领域发力的一些看法。这比区块链本身，要精彩的太多! Here's the answer to the question about what a block chain is. Here's what I think about the future of Central America in the financial sector of the block chain. It's much better than the block chain itself! 我在这里讲这么多区块链的优点，并不是为了给比特币唱赞歌。诚然，比特币是一个非常成功的经济学结合计算机技术的实验，它的成功也让这世界上最聪明的人看到了区块链颠覆当前世界货币体系和经济格局的可能性。比如说Facebook的扎克伯格。我们要理解昨天新闻的深刻用意，也需要将自己的眼光至少拔高到扎克伯格一样的高度。 I am here to speak of the virtues of so many block chains, not to sing a compliment to Bitcoin. Indeed, Bitcoin is a very successful experiment in combining economics with computer technology, and its success has made the world’s smartest man see the potential of block chains to destabilize the current world monetary system and economic landscape. For example, Facebook’s Zuckerberg. We need to understand the deep intentions of yesterday’s news, and we need to raise our eyes to at least the same height as Zuckerberg. 我们在提到区块链的洗钱风险、难以监管、难以控制的时候，往往会不自觉地想到国家一定会对其进行打压，因为它不利于国家的经济秩序。 When we refer to the risk of money-laundering in the chain of blocks, which is difficult to regulate and difficult to control, we tend to think unwittingly that the State will put pressure on them because it is not conducive to the economic order of the State. 但是，如果我们不是总想着怎么去防守它对我们可能的伤害，而是把它打磨成一柄利刃，用于开疆拓土、远播华夏文明呢?如果，我只是说如果，我们不把区块链金融用在本国经济体系中，而是用于整个世界经济体系呢? But what if we don't always think of how to defend ourselves against what it might do to us, but rather grind it into a blade that can be used to spread the land and spread the summer civilization? If, I'm just saying, what if we don't use block-chain finance in our own economic system, but in the world economy as a whole? 正如之前所述，区块链金融和银行相比，有三个非常突出的优势： As noted earlier, there are three distinct advantages to block chain finance and banks that are very : 1、一键开立账户，无需身份证明等任何手续 One, one key to open an account without any formalities such as identification. 2、发行量公开透明可控制，无需担心币价大幅贬值 2. Open and transparent distribution can be controlled without fear of significant devaluations of currency prices 3、抗审查、抗冻结 3. Counter censorship, counter-freezing 这三个特点对本国经济体系可能会带来负面影响，但如果用于进入他国经济体系，却是三把极其锋利的尖刀。 These three features may have a negative impact on the domestic economic system, but if used to enter the economic system of other countries, they are three sharp edges. 我们大胆的想象一下，无比方便好用的支付宝/微信移动支付加上杀不死的区块链金融/比特币，我们可以得到什么： Let's be bold and imagine what we can get from the conveniently useful payment treasures/micro-movements plus the indestructible block chain finance/bitcoin: 无需设立任何银行网点，无需和任何国家达成协议，就可以让全世界各个角落的人，仅通过一部手机，就使用人民币或者由中国控制的数字货币进行结算。而且最狠的是：其他国家想禁止也禁止不了。 There is no need to set up any banking point, and no need to reach an agreement with any country, to allow people from all corners of the world to settle through just one cell phone, using the renminbi or digital currency controlled by China. And, worst of all, other countries can’t ban it. 我们可以得到这么一种新型世界通用货币和新型APP产品： We can get a new world universal currency and a new APP product: 远的不说，这至少可以马上大幅改善全球数十亿尚无银行账户的人们的生活方式。他们将可以一键获得自己的全球通用免费账户，货币将无需担心突然贬值或账户被冻结。 Far from saying that this could at least immediately significantly improve the way of life of the billions of people around the world who do not have bank accounts. They would have access to their own universal free accounts at one key, and the currency would not have to worry about sudden devaluations or the freezing of accounts. 毋庸置疑，这个新型世界通用货币将是未来货币的新形态，也是这次数字世界货币战争的终极战利品。谁将是新的世界金融规则制定者? There is no doubt that this new universal currency of the world will be the new shape of the future currency and the ultimate prize of this digital world monetary war. Who will be the new world financial ruler? 人民币国际化已经进行了很多年，但其终究还是在原有世界格局下的存量竞争，需要一国一洲攻城拔寨。如果，我们能够成为新型世界货币的规则制定者，从下至上颠覆整个世界货币格局，会不会更有趣? The renminbi has been internationalized for many years, but it still competes in stocks in the old world, requiring one nation to take over the city. Wouldn’t it be more interesting if we could become the rule-makers of the new world currency, undermining the world’s currency from the bottom up? 就在两天前，美国国会对Facebook的数字货币Libra计划进行了长达六小时的问询。期间，扎克伯格说：“我不知道我能不能搞成，但支付宝和微信都在拼命搞区块链，我们再不搞，中国就搞出来了。” Just two days ago, the U.S. Congress questioned Facebook's digital money, Libra, for six hours. During that time, Zuckerberg said, "&ldquao; I don't know if I can do it, but payment treasures and micro-letters are working hard on block chains, and if we don't, China will." And & rdquao; 数字世界货币战争的号角已经吹响，各位勇士们，准备好了吗? The horns of the Digital World Monetary War have been blown. Are you ready, warriors? 看了大家的回复以及其他关于区块链的答案，想讨论一个问题： Looking at your responses and other answers to the block chain, I would like to discuss a question: 区块链真的去中心化吗?有多去中心化呢? Do you really have to centralize the block chain? How much? 我先给我的观点，区块链的去中心化是一个美好的设想，目前在实际应用中，远远没有大家想象的那么去中心化。 Let me start by saying that the de-centralization of the block chain is a good idea, and it is far from being so central in its practical application. 绝大多数情况，都是一个人，或者个位数的中心化组织或个人垄断了51%以上的算力。 In the vast majority of cases, more than 51 per cent of the computing power is monopolized by a person, or by a centralized organization or individual of a number. 就拿大家熟悉的比特币来说，几乎所有的人都在说比特币是去中心化的，有几万几十万台分布在世界各地的矿机，几乎杜绝了串谋舞弊的可能性。 In terms of the well-known bitcoin, almost all people are saying that bitcoin is decentralized, with tens of thousands of mine machines scattered around the world, virtually eliminating the possibility of complicity. 但真实情况果真如此吗?下图是我随手在网上找的2018年比特币矿池算力占比图。 But is that true? The next picture is the bitcoin pond arithmetic of 2018 that I've been looking for online. 算力分布的概念和矿池的概念我就不展开讲了。百度和知乎都有很好的答案。但通过这张图你可以很明显的看到，即使是被吹上了天的去中心化数字货币比特币，也并不是一个理想中人人平等，完全去中心化的状态，而是由几个资金实力极为雄厚的大矿池和大矿主垄断了算力。 The concept of arithmetic distribution and the concept of a pond is not open to me. There are good answers in both degrees and in terms of knowledge. But it is clear from this picture that even the decentralized digital currency, bitcoin, which is blown out of the sky, is not the ideal place for all to be equal and completely decentralized, but for a few very powerful big ponds and big miners to monopolize the calculus. 我无意去抨击矿池和矿场的老板，因为这其实是事物发展所必然的结果。而且他们很多都是区块链行业的先驱，为区块链的发展实实在在的做了很多贡献。但我只是想说明一个事实，即：区块链不等于极度分散和完全去中心化。也没有这个必要。 And many of them are pioneers in the block chain industry, making a real contribution to the development of the block chain. But I just want to make clear the fact that the block chain is not highly dispersed and completely de-centralized. 那么为什么无法完全去中心化会是比特币的必然结果呢? Why can't it be completely centralized as a logical consequence of Bitcoin? 因为比特币挖矿可以赚钱，而规模效益可以提高这个赚钱的效率。 Because bitcoin digs can make money, and economies of scale can increase the efficiency of this money. 最早的时候比特币卖不了钱，所以算力很分散，大家都是玩玩的。但随着比特币越来越值钱，越来越多的人就开始算经济账了。 Bitcoin couldn't sell the money at the earliest, so it's fragmented and everybody's playing. But as bitcoin gets more and more valuable, more and more people start counting. 比特币挖矿拼的是机器的算力，好的机器可以只用一百度电就可以挖100美元的比特币，不好的机器要一千度电才能挖100美元。而好的机器，需要资本投入去研发、生产。 Bitcoin digs the machine's arithmetic, and a good machine can dig $100 with 100 degrees of electricity, and a bad machine can dig $100 with 1,000 degrees of electricity. And a good machine needs capital to invest in research and development. 同理，挖矿所产生的电费，一般人是6毛钱一度，而有规模效应的大矿场，可以做到2毛到4毛。 Similarly, the cost of electricity generated by mining is typically 60 cents a day, while large mining sites with a scale effect can do between 20 and 40 cents. 在这种情况下，必然会造成强者恒强，弱者不断被淘汰，算力越来越集中。 In such cases, it is inevitable that the strong will be strong, the weak will be phased out and the counting will be increasingly concentrated. 那么你也许会问，比特币是这样，那其他的区块链项目呢? Then you might ask, "This is what Bitcoin is, what about the other block chain projects?" 很遗憾，都差不多。 Unfortunately, it's all about that. 而且每隔段时间就会有新的人跳出来说自己解决了这个问题，但一旦开始赚钱了，就还是逃不过规模效益这个简单又强大的经济学定律。 And every once in a while, new people come out and say they've solved the problem, but once they start making money, they can't escape the simple, powerful economic law of scale. 以上就是区块链到底是啥?区块链是什么通俗解释的详细内容，更多关于区块链通俗解释的资料请关注脚本之家其它相关文章！ That's what the block chain is.
