看到这个问题，相信很多投资者都想要了解，毕竟网传，数字货币区块链，是传说中猪都能飞起来的行业，数字货币区块链于2018迅速出现在大众的视野中，现在上到行业从业者，下到路边卖煎饼果子的大妈，都在讨论数字货币区块链，那么到底什么是数字货币区块链呢？下面币圈子小编就来给大家通俗的讲解一下数字货币区块链，希望通过本文的介绍，投资者对数字货币区块链有初步认知。
Looking at this problem, many investors believe they want to understand that, after all, the digital money block chain is an industry in which the legend says pigs can fly, that the digital currency block chain quickly appears in the public eye in 2018, and now goes up to industry practitioners, down to the road to sell pancakes, and the moms are talking about the digital currency block chain, so what is the digital currency block chain? Under the coin circle, the small editor will explain the digital currency block chain in a popular way, hoping that through this presentation investors will have a preliminary idea of the digital currency block chain.
数字货币是一种数字交易媒介，使用强大的密码学技术来确保金融交易的安全，控制额外单位的创建和验证资产的转移。
Digital money is a digital trading medium that uses powerful cryptography techniques to ensure the security of financial transactions and controls the creation of additional units and the transfer of proven assets.
这里有几块可以关注：数字、强密码、创建、交易和验证。
Here are a few pieces that can be noticed: numbers, powerful passwords, creation, transactions and authentication.
为什么比特币是一个如此革命性的技术?很大程度上是由于它的设计防止了一个叫 “双重消费 “的问题。
Why is Bitcoin such a revolutionary technology? Much because its design prevents a problem called & ldquo; double consumption & & ldquo;
为了让你知道你刚刚收到的1美元不会被你的发件人在另一笔交易中再次消费，我们通常需要相信有人来记录谁花了什么，收到了什么，通常是银行，在数字资产的情况下，或者是一元纸币本身实际离开你的钱包，永远不会回来。
In order for you to know that the dollar you have just received will not be consumed again by your sender in another transaction, we usually need to believe that someone records who spent what, what was received, usually a bank, in the case of digital assets, or that a dollar itself actually leaves your wallet and never comes back.
有了比特币，对这一问题的认识和预防，意味着我们再也不用怀疑刚刚给我们的一元钱是否真的可以被发币人花掉，也不需要中间人去验证。这就类似于你钱包里的现金。一旦你把它送出去了，你就可以亲眼看到它已经不在了。
With bitcoin, awareness and prevention of the problem means that we don't need to question whether the dollar money that we just gave us can really be spent by the sender, nor do we need an intermediary to verify it. It's similar to the cash in your wallet. Once you get it out, you can see it's gone.
这个概念是革命性的，因为这些都是数字资产，过去需要有人验证交易。
The concept is revolutionary, as these are digital assets that in the past required a validation of the transaction.
对于比特币来说，每一笔交易都会被添加到一个”区块 “中，然后被追加到一个区块链的末端，也就是 “区块链 “中，一旦被确认，任何人都无法篡改之前的区块。这是通过强加密技术，使用一种叫做SHA-256加密哈希函数的东西来完成的。
For Bitcoin, each transaction is added to a ” block & & ldquo; and then to the end of a block chain, i.e. & & & & & & ldquo; in which, once confirmed, no one can alter the previous block. This is done by means of a powerful encryption technique that uses an object called the SHA-256 encrypted Hashi function.
那么这些比特币到底是怎么来的呢?作为确认区块链上交易的过程的一部分，有一些人被称为矿工，他们运行计算机或芯片来解决密码学难题，竞相向区块链添加新的区块。为了奖励这些矿工在维护网络安全方面的贡献，每增加一个区块就会产生新的比特币。
So how did these bitcoins come? As part of the process of identifying transactions on the block chain, some people are called miners, who run computers or chips to solve cryptography problems and compete to add new blocks to the block chain. In order to reward the contribution of these miners in maintaining cyber security, each additional block will produce a new bitcoin.
我们之所以需要矿工作为区块链的一部分，是因为安全问题。在工作量证明系统下，必须花费现实世界的资产，如电力，来确认区块：在获得奖励之前，会产生成本。
The reason we need mining to be part of the block chain is because of security issues. Under the workload proof system, real-world assets, such as electricity, have to be spent to identify blocks: costs before getting incentives.
在这个系统下，不良行为者攻击区块链的成本变得很高，因为他们需要在攻击中花费大量的资源;由于其他人的行为是为了合法地接收比特币，以换取他们在挖矿中的努力，这些攻击者几乎没有机会接管51%的网络，并有效地控制大多数。
Under this system, the cost of attacks on the block chain by undesirable actors becomes high, as they need to spend a great deal of resources in the attack; as others act in order to legally receive bitcoin in exchange for their efforts in mining, the attackers have little opportunity to take over 51 per cent of the network and effectively control the majority.
还有其他形式的共识机制，比如权益证明、委托股权证明、授权证明、烧毁证明、开发者证明等等。每种机制都有自己的优点和缺点，所以要花时间通过自己最感兴趣的项目来了解每种机制。
There are other forms of consensus mechanisms, such as certificates of interest, certificates of ownership, certificates of authorization, certificates of burning, certificates of developers, and so on. Each mechanism has its own strengths and weaknesses, so it takes time to learn about each mechanism through its own projects of greatest interest.
区块链是保证数字货币安全性使用的一种技术，大家都知道区块链技术具有加密性及不可篡改性两大特点，能够将数字货币在使用过程中出现差错的几率降低到0。由于数字货币对加密性要求更高，故而一定要用到区块链技术对其进行支持的，目前，不仅我国多个行业都在使用区块链技术，乃至国外多个国家也在积极使用区块链技术。
