区块链就是一种网络技术，通过程序员敲代码形成的网络，各方相互合作交易均可直接对接完成，不需要靠第三方平台，也就省去了中间的一些程序和费用(省时省力还省钱)，但为了合作或交易的安全，系统会将每一个参与者的动作广播给所有参与者，保障了整个过程的安全、透明，解决了信任问题。
区块链技术被认为是继蒸汽机、电力、互联网之后，下一代颠覆性的核心技术。 如果说蒸汽机释放了人们的生产力，电力解决了人们基本的生活需求，互联网彻底改变了信息传递的方式，那么区块链作为构造信任的机器，将可能彻底改变整个人类社会价值传递的方式。
Block chain technology is considered to be the core of the next generation of subversive technologies that follow steam machines, electricity, and the Internet. If the steam engine releases people’s productivity, electricity addresses people’s basic needs for life, and the Internet radically changes the way in which information is transmitted, the block chain, as a machine that builds trust, can radically change the way in which the values of human society as a whole are transmitted.
区块链是一种去中心化，去中介化，信息不可篡改，公开透明，集体维护，有可靠数据库的一种技术，通过增加信任，成本降低，效率提高，能发挥个人和个体的价值上链，这里的加密技术Hash（哈希算法），算力是权利。

我们用2个最通俗易懂的例子来解释。
We explain it with two of the most popular and understandable examples.
区块链就是一种去中心化的分布式账本数据库。这种分布式账本的好处就是，买家和卖家可直接交易，不需要任何中介。人人都有备份，哪怕你这份丢失了，也不受影响。如借贷事项如下：我向阿梅借了10块钱。阿梅在想：怎么能杜绝赖账呢？
The block chain is a decentralised database of distributed accounts. The advantage of this distribution is that buyers and sellers can deal directly without any intermediary. Everyone has a backup, even if you lose it. The lending is as follows: I borrowed 10 dollars from Ame. Ame wonders: How can we stop the default?
除了用传统文化摄持，借贷双方如何能杜绝赖账呢？
In addition to traditional culture, how can both lenders and borrowers put an end to debt?
全村所有人都记下了：乐仔向阿梅借了10块钱
Everyone in the village wrote: Lok borrowed $10 from May.
如此，村（系统）中的每个人，共同认定记录一笔交易。把“线下独立记账”升级为“线上全民记账”，这种方式称为区块链技术！（有点像在群里公布信息@所有人）
This is the case for everyone in the village, jointly, to record a transaction. To upgrade the word "underline independent accounts" to "online public accounts" is called block chain technology! (It's kind of like publishing information in a group @owner)
我们再用谈恋爱举例。
Let's give you another example of love.
建立一个简单的区块链模型，那么在这个区块链模型里面谈恋爱将会出现一下情况：
Create a simple block chain model, so that in this block chain model there will be a situation:
未来所有适龄男女恋爱，结婚的承诺全过程都被其他所有适龄男女共识，两个人在一起发生的所有故事就会形成区块。
In the future, all men and women of the right age fall in love and the commitment to marry is shared by all other men and women of the right age, and all the stories that happen between the two individuals form blocks.
其他所有男女就是链，如果有第三者来插足或自身违背另一半，其他人都能看到，以后就再也找不到对象了。
All other men and women are chains, and if there is a third person to intrude on or violate the other half, others will see it, and they will never find the target again.
区块链准确的说就是“全中心”体系，就是链上的每个节点都是中心。
试婚男女谈恋爱，晒朋友圈，秀恩爱，承诺相爱一生一世并被其他所有适婚男女所知就是区块链的应用。如果有一天某一方违背诺言，不要以为删除照片就有用，因为桩桩件件都被所有适婚男女记录在案。 If one day one of the parties breaks its promise, don’t think that it is useful to delete the photo, because the pieces of the plaque are recorded by all married men and women. 不可删除，不可更改，这就是区块链技术。 is irrevocable. This is block chain technology. 若将此技术应用至商业领域，其对商业环境的“净化”效果将可想而知，这也就解释了区块链技术为什么这么火。 The “purification” effect of this technology on the business environment would be expected if it were applied to the commercial sphere, which would explain why block chain technology is so hot. 应用场景：互联网进入生态时代，其应用已渗透到金融服务、物联网、供应链管理、数字资产交易、电子商务等多个领域。区块链的出现，使得互联网发展从信息互联网到价值互联网、秩序互联网转型，其以共享经济与价值链接为主要特征的“分布式商业”模式，将催生大量的跨机构新型创新合作场景，构建起以区块链技术为虚拟中心的新产业生态系统，将对经济社会治理、产业变革与创新产生颠覆式影响。 application: The Internet has entered an ecological era, and its applications have permeated multiple areas such as financial services, physical networking, supply chain management, digital asset trading, and e-commerce. The emergence of block chains has transformed the Internet from information Internet to value Internet, order Internet development, and its “distributive business” model, characterized by shared economic and value linkages, will generate a large number of innovative, inter-institutional collaborative scenarios, and will create a new industrial ecosystem with block-chain technology as a virtual centre that will have a destabilizing impact on economic and social governance, industrial change and innovation. 注：区块链世界里流行着一个“不可能三角理论”——一个区块链系统无法同时兼顾去中心化（Decentralization）、可扩展性（Scability）/ 效率、安全性（Security）。这也就意味着当你认定去中心化必须坚守时，你就被迫在效率和安全之间选择一个牺牲。 Note: a “triangular theory” is prevalent in the world of block chains — a block chain system that does not take into account decentralisation, scabilization/efficiency, security. 举个形象的例子。A 跟B借了100块钱，并要找C当公证人，按照市场价A和B两人一共要给C 10元中介费。于是A当着C的面向B承诺他下一个星期一定会还这100元。但是下个星期过完了A也没有向B还钱。B 很生气于是去找C希望C能证明A曾经向自己借过一百元。但是C却不承认A 曾向B借过100元。可能有这么几种原因：一是A向C行贿，说如果C不承认A和B之间的借约，那么A借来的100元可以跟C分。二是C因各种不可抗力因素失忆了，三是C打算以A和B之间的借约为筹码狠狠敲诈B一番，如果B不多给几块钱C就不承认A与B之间的借约，坐地起价。于是B就很倒霉地要么得多付钱，要么就失去了100元。另一种情景就是B耍赖反悔声称A向B借了不止100元。无论哪一种情形都是很不公平的。 For example, A borrowed $100 from B and asked C to be a notary to pay a total of C10 for mediation at the market price of A and B. So A promised him $100 in the next week. But he did not pay B next week. B was angry to look for C to prove that A had borrowed $100 from itself. But C denied that A had borrowed $100 from B. There might be several reasons: A bribed A to C, and if C did not recognize the loan between A and B, then A borrowed $100 from C, then he could split it with C. Second, C lost memory for various force majeure factors. Third, C was planning to blackmail B with some leverage between A and B. If B did not lend a few dollars, B did not recognize the loan between A and B, the price would have been much less than 100 dollars, or 100 dollars. 那么如果一开始A向B借钱时就采用区块链技术的原理来记录这次借约，情形又会是怎样的呢？ What would have happened if A had used the principle of block chain technology to record the loan in the first place? A去找B借100块钱。于是两人请来了字母世界除了他们以外的剩下24个字母，CDEFGHIJKLMNOPQRSTUVWXYZ，全部到现场见证A向B借钱，并且每个字母都把“某年某月某日某分某秒，A向B借了100元”这一事件及它发生的时间【时间戳】记录下来。所以如果AB中有一人想使诈，想让字母们记录错误的信息，他必须贿赂字母世界一半以上的字母（大于等于13个字母）才有可能实现，这就是【51%攻击】。因为贿赂成本极高，所以理论上来说没有人会这么做。“A找B借了100元”这一信息就会被真实地记录下来。 A went to B for a hundred dollars. So two people asked the Alphabet World to record the remaining 24 letters, except for them. So if one of the ABs wanted to trickle down and let the alphabets record the wrong information, he had to bribe more than half of the letters of the Alphabet World (more than 13 letters) to borrow money from A to B, and that's why 51% of the letters attacked . No one would do so in theory because of the high cost of bribery. A和B协商只花5块钱作为中介费，要把这5块钱分给24个字母，怎么分配也是问题。全部平均分的话，无法激励字母们提高工作效率，容易出现有的字母没有干劲，滥竽充数，随便乱记录（人民公社时期吃大锅饭）；所以要怎么分配这5块钱需要所有字母一起协商达成共识【共识机制】。所以说“共识机制”就是各方均同意认可的生产资料分配制度。目前区块链技术中比较有人气的分配方式有“工作量证明机制【POW】”, “权益证明机制【POS】”, “股份授权证明机制【DPOS】”,和“拜占庭容错算法”。 It is also a question of how to allocate the $5 as an intermediary fee. The average score is not enough to motivate the letters to work more efficiently. It is easy to record the existing letters without energy, effort, effort and effort. So how to allocate the $5 requires all letters to agree on a consensus mechanism . So the "consensus mechanism" is an agreed system of distribution of production information. The "strong" is the "strong" system. The current method of distribution of block technology is the "strong" workload certification mechanism < < strong > > ; and "strong < strong > > ; and "strong < < < strong > > ), share authorization mechanism < < < strong > > >. 因为记录事件是在数字世界中完成的，所以达成的共识以及记录的事件需要用计算机算法来表示。为了保护数据不被人盗取，保护用户的隐私，就需要把原来用明文表示的数据信息按某种算法进行处理，把明文信息转化成加密数据【加密算法】。
