（干货）区块链的神秘特点，你知道吗？
别慌，就连马云都说，阿里巴巴刚开始投资区块链的时候，他根本就不懂这是什么。
Don't panic, even Maun said that when Ali Baba started investing in the chain , he didn't know what it was.
那么马云为什么愿意投入巨资研发区块链技术呢?今天CD就来帮大家科普一下区块链的魅力。
So why would Ma Yun want to invest heavily in developing block chain technology? Today CDs will help you find the charm of block chains.
区块链的神秘本质
The mysterious nature of the block chain.
我们先把神秘的密码学、数学、经济学概念和算法暂时放在一边，来看看区块链技术的一个显著特点——去中心化。
Let us first put aside mythology, mathematics, economic concepts and algorithms for the time being, and look at one of the salient features of block chain technology — de-centralization.
去中心化，就是每个人都是一个分布式的中心。
To centralize is that everyone is a distributed centre.
区块链在个人计算机网络上存储信息，使其不仅去中心化而且分布式。
Block chains store information on personal computer networks so that it is not only centralized but also distributed.
这个特性非常重要，因为这意味着任何一个人都很难垄断或破坏区块链上的账户和信息。
This feature is very important because it means that it is difficult for any one person to monopolize or destroy accounts and information in the chain of blocks.
这很重要，因为这意味着任何一个人都很难摧毁或破坏网络。
This is important because it means that it is difficult for anyone to destroy or destroy the network.
知乎上有个危险人物在线挑战支付宝底线，提了一个触犯刑法的问题↓↓
Knowing that there's a dangerous person online challenging the payment of the bottom line, there's a criminal offense problem.
支付宝工作人员用7个屏幕解释了他们为保障安全投入了多少人力物力，还挖出了2005年的一句承诺：如果支付宝账户被盗，造成损失，我们全额赔偿。
The paid treasure workers used seven screens to explain how much they had invested in security, and dug up a promise from 2005 that if the paid treasure account had been stolen and lost, we would pay in full.
如果应用区块链技术，这个问题基本上就不是什么大问题了，为什么呢？
If
账本并不掌握在支付宝这样的中央第三方手中，而是分散在众多点对点参与者手中。 The books are not in the hands of central third parties, such as payment treasures, but are dispersed among multiple point-to-point participants. 在区块链网络中，每个参与者都可以参与记账，系统会选取速度最快、质量最高的记账记录，将其内容写入账本，并发送给系统内所有人查看。 In the block chain network, each participant can participate in bookkeeping, and the system will pick up the fastest and highest-quality record-keeping records, write their contents into the accounts and send them to everyone in the system for viewing. 理论上，你必须销毁 51% 参与者的账户才能实施欺诈，但这基本上是不可能的。 Theoretically, you have to destroy 51 percent of the participants' accounts in order to commit fraud, but that's basically impossible. 这就是为什么专家说区块链非常安全，因为与公司或政府机构拥有的集中式数据库不同，区块链不受任何个人或实体控制，并且数据在多台计算机上完全复制（分布）。与集中式数据库不同，攻击者没有单一的入口点，数据更安全。 This is why experts say that block chains are very secure, because, unlike centralized databases owned by companies or government agencies, block chains are not controlled by any individual or entity, and data are fully copied (distributed) on multiple computers. Unlike centralized databases, the attackers have no single entry point and the data are safer. 所以区块链的应用就是建立点对点的信任，避免像支付宝这样的中心化，真正实现没有第三方赚取差价利润的交易。就这么简单吗？当然不是！ So the use of block chains is to build a point-to-point trust, to avoid centralization like payment treasures, and to make a real deal without a third party making a margin profit. Is that so simple? Of course not! 这是怎么做到的呢?这是由区块链的第二个特点决定的。 How does this happen? It's determined by the second characteristic of the block chain. 信息一旦进入区块链，以目前的计算能力来说，几乎是不可改变的，就连管理员也无法修改这些信息。 Once the information enters the block chain, it is almost immutable in its current computing capacity and cannot even be modified by the administrator. 区块链是由一组包含信息的信息块组成的信息链。区块链技术最初是由一组研究人员开发的，用于对数字文档进行时间戳记，以便它们无法追溯或篡改。区块链技术看起来像一个公证人。 The block chain is an information chain consisting of a set of information blocks. The block chain technology was originally developed by a group of researchers for time stamping digital files so that they cannot be traced or tampered with. The block chain technology looks like a notary public. 区块链是包含信息的区块链。这项技术最初由一组研究人员描述，最初旨在为数字文档添加时间戳，这样就不可能追溯或篡改它们。几乎就像公证人一样。 The block chain is the block chain that contains information. This technique was initially described by a group of researchers and was originally designed to add a time stamp to the digital file so that it was not possible to trace or tamper with them. Almost like a notary. 事物一旦出现，就永远无法改变，这一特性对于人类目前所处的瞬息万变、可修改的网络世界来说，具有重要意义。 As soon as things emerge, they will never change, a characteristic that is important to the instantaneous, modified networked world in which humankind is currently living. 谁来验证网上购买的奢侈品的真伪？ Who will verify the authenticity of luxury ? 多位奢侈品店工作人员表示，不少海外购物者都要到实体店比货、辨别真伪，有些人从实体店购买奢侈品，只是为了带回家比货，比完再退货。 According to several luxury shop staff, many overseas shoppers are required to compete with the real store and to identify the truth, while some buy luxury goods from the real shop only to bring home the match and return it. 虽然有各种权威机构为消费者提供支持，但收集证据、提起诉讼等一系列举证程序极其繁琐，许多人望而却步，宁愿默默忍受。 While there are various authorities that support consumers, a range of evidentiary procedures, such as evidence-gathering and litigation, are extremely cumbersome, and many are reluctant to accept it in silence. 如果区块链技术能够充分运用在贸易领域，那么这种客观的公证将会发挥极大的监督和取证作用。 This objective notarization will play a significant monitoring and evidentiary role if block chain technology is fully applied in the area of trade. 只需检查区块链中的货物和资金流是否同步即可。 It is sufficient to check whether the goods and financial flows in the block chain are synchronized. 当前各国的身份验证体系都需要投入大量的人力和物力进行审计和记录核实，而区块链技术不可复制、去中心化、不可篡改、透明化的特点无疑可以很好地弥补传统身份验证体系速度慢、成本高、存储复杂的不足。 Currently, national identification systems need to invest considerable human and material resources in auditing and record-checking, while block chain technology is not replicable, decentralized, non-manufacturing and transparent features can certainly well compensate for the slowness, high cost and complex storage of traditional identification systems. “我的妈妈就是我的妈妈”？ "My mother is my mother"? 区块链给你证明 I'll show you the chain of blocks. “我要怎么证明我妈妈就是我妈妈呢！” "How can I prove that my mother is my mother?" 在《区块链：重塑经济和世界》一书中，作者分享了这样一个例子： In the book " Block chains: reshaping the economy and the world ", the author shares such an example: 北京居民陈先生一家三口计划出国旅游chains是什么意思，需要确定亲属作为紧急联系人，于是他想到了母亲，但问题在于，他需要一份书面证明，证明他和母亲是母子。 What does Mr. Chen's three-member family plan to travel abroad 陈先生在北京的户口本上只显示了他本人和妻子、子女的信息，而他父母在江西老家的户口本上已经没有陈先生的信息。 就在陈先生为此苦恼不已时，有人指出了一个明确的解决办法：可以到父母户口所在地的派出所去办个证。 At a time when Mr. Chen was troubled by the problem, a clear solution was pointed out: a certificate could be issued at the police station where the parents' residence was located. 且不论派出所能不能顺利开具这张证明，光是想到要跑近千里路去办这张证明，就已经让人头疼、气愤不已。 Whether or not the police station can easily issue this certificate, the mere thought of running a thousand miles to do it is already a headache and an outrage. 利用区块链技术，例如采用分布式智能身份认证系统英语作文网，所有信息都可以被证明是不可篡改的，并被准确记录，这将防止私人信息被泄露给不法分子，并且在需要时可以立即提供所有信息的证明。 Using block chain technology, such as the distributed smart identification system English-language writing network , all information can be shown to be immutable and accurately recorded, which will prevent private information from being leaked to outlaws and, when needed, provide proof of all information immediately. 如果区块链技术得到广泛应用，每个人都可以通过家庭关系证明自己的存在和身份，个人信息被记录在区块链上，就像一个分布式公共账本。 If block chain technology is widely applied, each person can prove his or her existence and identity through family ties, and personal information is recorded on the block chain, like a distributed public account book. 还记得2016年8月那条震惊世界的新闻吗？吉林省人刘俊良因误会，被困在德国难民营12天。 Remember the news of August 2016 that shocked the world? Liu Junlian of Jilin province was trapped in a German refugee camp for 12 days because of a misunderstanding. 31岁的刘俊良作为一名背包客前往欧洲，没有任何同伴，没有翻译，没有词典，没有导游，更不懂英语。 Liu Jun Liang, 31 years old, travelled to Europe as a backpacker, without any companions, no interpreters, no dictionaries, no guided tours, and no English language. 刘俊良在德国斯图加特机场刚下飞机，钱包就被盗。 Liu Junlian just landed at Stuttgart airport in Germany and his wallet was stolen. 无奈之下，他决定向警察求助，但由于他不会说德语和英语，无法问路，只好摸索着来到一个像市政厅的地方，因为那里有很多穿着警服的人。 Unable to do so, he decided to turn to the police, but because he did not speak German or English and could not ask for directions, he had to go to a town hall, where there were many people in uniform. 此时此刻chains是什么意思，我可以想象那些语言不通的人们是如何交流的..&*%....#_*&%@`>…. At this point in time, what do you mean by strong'chains?.................................................................................................................... 于是，在茫然之中，他的护照被没收，并被送往距离斯图尔特约 220 英里（四小时车程）的多特蒙德。 As a result, his passport was confiscated and sent to Dotmond, some 220 miles from Stewart (four hours' drive). 然后，他被要求填写庇护申请表、采集指纹并接受体检。 He was then asked to fill out an asylum application form, take fingerprints and undergo a medical examination. 最后，由于刘俊良无法证明自己，他和其他50名难民被送往北威州小镇新建的杜尔门难民收容所。 Finally, as Liu Jun Liang was unable to prove himself, he and 50 other refugees were taken to the newly built Durmen refugee shelter in the town of North Wales. 理想情况下，如果区块链核心技术能够最大程度地得到有效合理利用，甚至在国际上得到应用，那么刘俊良证明自己不是难民将是轻而易举的事，并不是什么需要12天才能完成的艰巨任务。 Ideally, if the core technology of the block chain were to be used to the maximum extent effectively and rationally, and even internationally, it would be easy for Liu to prove that he was not a refugee and not a difficult task that would take 12 days to accomplish. 对区块链的误解 Misunderstanding of block chains
比特
Currently, the popular understanding of block chains is mainly through coin, which is easily mistaken for a “currency” because of the advantage of bitcoin, and because of the extreme volatility of bitcoins, many people mistakenly assume that the chain is an economic bubble.
马云曾经说过，区块链不是泡沫，比特币才是。而且区块链不是金矿，不可能一夜暴富。区块链要解决的是社会问题，是解决隐私和信用问题的技术。
Ma Yun once said that block chains are not bubbles, they are bitcoin. And that block chains are not gold mines, they can’t be rich overnight.
区块链创新发展已经上升为国家战略，我们要坚定决心，做好长远规划，决不能想着赚快钱，决不能脱离实体经济，成为投机的温床。
The innovative development of the block chain has risen to a national strategy, and we must be committed to long-term planning. We must not think of making quick money. We must not move away from the real economy and become a breeding ground for speculation.
在应用方面，我们也需要注意到，区块链并不是“包治百病”的良方，应重点发挥其优势，同时也要结合实际发展情况，找准需要解决的“痛点”。
In terms of application, we also need to note that the block chain is not a “one-size-fits-all” solution and that it should focus on its strengths, while at the same time identifying painful points that need to be addressed in the light of actual developments.
