区块链是一种去中心化的分布式账本数据库。通俗一点说，区块链技术就是一种全民参与记账的方式。
The block chain is a centralized distributed account database for 所有的系统背后都有一个数据库，可以把数据库看成就是一个大账本。那么，谁来记这个账本就变得很重要。 There's a database behind all of 我们当前的情况就是中心化的记账方式，即谁的系统谁来记账。 Our current situation is one of centralizing the way that accounts are kept, that is, who's the system that keeps the accounts. 比如：你们家里有个账本，让你来记账。在以前，就是爸爸妈妈把工资交给你，让你记到账本上。中间万一你贪吃，想买点好吃的，可能账本上的记录会少十几块。 For example, you have a book of accounts in your house that you can keep. In the past, Mom and Dad gave you your salary, so you could put it on the books. In case you want to buy something good, maybe you'll have a dozen less on the books. 用区块链解决问题的方法：如果用全家总动员的方式记账，上述说的问题就不会有了，因为你在记账，你爸爸也在记账，你妈妈也在记账，他们都能看到总账，你不能改，爸爸妈妈也不能改，这样想买烟抽的爸爸和想贪吃的你都没办法啦。 uses a block chain to solve the problem: can't be the problem because you're in charge, your father's in charge, your mother's in charge, they can see the general account, you can't change, your parents can't change, you can't buy a smoker's dad and you can't afford to eat. 也就是说，区块链这个分布式的数字账本，记录了所有曾经发生并经过系统一致认可的交易，每个区块就像一个硬盘，把以上这些信息全部保存下来，再通过密码学技术进行加密。这些被保存的信息就无法被篡改。 In other words, the distributed digital account of the 扩展资料： extensions: 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。 Bitcoin is a very successful experiment in combining economics with computer technology, and its success has shown the world's smartest people 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 look at ourselves at at least as high as Zuckerberg. 区块链金融和银行相比，有三个非常突出的优势： There are three distinct advantages to block-chain finance and banking: 1、一键开立账户，无需身份证明等任何手续。 1, 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。 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. 参考资料来源：百度百科-区块链
区块链是用来共同记录公共数据的，或者更狭义的说，用来记账的一种数据库。
过去，我们的信用需要一种中心化的权威背书，譬如一些权威只有政府才具备，譬如主权货币只有中央银行在国家的背书基础上才能充分民众获得信任。现在不同了，通过区块链技术，我们每个人之间都可以通过一种“标准”、“规则”来实现信任。
In the past, our credibility required a central and authoritative endorsement, for example, that some authorities were only government-owned, and that sovereign currencies could be trusted only by the central bank on the basis of a state-endorsed endorsement. Now, through block chain technology, trust can be achieved by a “standard” or “rule” between each of us.
譬如，现在你去市场买个螺丝帽，在知道螺丝型号后，你只要告诉商家你要购买螺丝帽型号，你就不必担心螺丝拧不上，因为螺丝型号国际标准化的，全世界都一样。这就是标准、规则的力量。区块链，本身就是基于计算机网络技术的标准化，是基于规则的标准化。通过计算机网络技术，使得这些规则、标准在所有相关事物的运行过程中成为准绳，从而让事情变得透明、可信，并据此形成信任逻辑。
For example, now you go to the market to buy a screw cap, and when you know the screw type, you just tell the merchant you want to buy the screw type, and you don't have to worry about it, because the screw type is internationally standardized, the same as the rest of the world. That is the power of standards and rules. The block chain is itself based on standardization of computer network technology, based on standardization of rules.
扩展资料： extensions: 多功能的区块链 multifunctional block chain 它不仅可以记录每一笔交易，还可以通过编程来记录几乎所有对人类有价值的事物：出生和死亡证明、结婚证、所有权契据、学位证、财务账户、就医历史、保险理赔单、选票、食品来源以及任何其他可以用代码表示的事物。 Not only can it record every transaction, but it can also be programmed to record almost all things of value to humanity: birth and death certificates, marriage certificates, title deeds, degree certificates, financial accounts, medical history, insurance claims, ballot papers, sources of food and anything else that can be coded. 比特币跟区块链的关系 The relationship between bitcoin and block chains 比特币的整个生态运用的就是区块链技术，比特币的产生，是因为通过某种巧妙的限制控制了比特币的增长数量和难度，因为比特币越来越值钱，也有越来越多的计算力去挖币，但是因为这种巧妙的限制，通过不断增加难度还是抑制了新的区块的增加。 The whole ecology of Bitcoin is based on block chain technology, and Bitcoin was created because of the fact that the growth of bitcoin was controlled by some subtle restriction, because bitcoin was becoming more valuable and more calculatory to dig for currency, but because of this subtle constraint, the growth of new blocks was curbed by increasing difficulty. 比特币的交易其实是运用一种不对称加密手段，每个比特币有一个地址，这个是公钥，持有者拥有私钥，通过私钥可以完成交易。因为区块链具有全网数据一致性的特点，所以每个人有哪些币，谁跟谁做了交易都是透明公开的，于是就有了整个生态和价值体系。 Bitcoin transactions actually use asymmetric encryption, with each bitcoin having an address, which is a public key, and the holder has a private key, which allows the transaction to be done through a private key. Because the block chain has the characteristics of full-network data consistency, everyone has what currency, who deals with whom is transparent and open, and there is an entire ecological and value system. 参考资料来源：百度百科-比特币
从技术的角度，架构的角度，用通俗的语言来跟大家讲讲，我对区块链的一些理解。
From a technical point of view, from a structural point of view, to speak in plain language, I have some understanding of the block chain.
究竟啥是区块链？Block chain，一句话来说，区块链是一个存储系统，存储系统更细一点，区块链是一个没有管理员，每个节点都拥有全部数据的分布式存储系统。
What is a block chain? Block chain, in short, is a storage system, with a more detailed storage system, and a block chain is an unsupervised system with all the data distributed at each node.
那常见的存储系统，是什么样子的呢？
What's a common storage system like?
