原标题：最近频频被点名的“区块链”，到底是个啥?
Original title: What is the "block chain" that has recently been named? & nbsp;
最近有一个词在网络上出现频率很高，看到这个词会让人觉得很厉害，但经常不确切知道是什么意思。这个词叫“区块链”。最近“区块链“又被公开点名，“区块链”到底是啥?
A term that has recently appeared on the web with a high frequency makes it feel good to see it, but it often doesn't know exactly what it means. The word is "block chain." Recently, the "block chain" has been “publicly named” and what is the “block chain”?
从学术角度来解释，区块链是分布式数据存储、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。区块链本质上是一个去中心化的数据库。
From an academic point of view, the block chain is a new application model for distributed data storage, point-to-point transmission, consensus mechanisms, encryption algorithms, etc. The block chain is essentially a decentralised database.
这么解释，很多人还是看不懂，那么小编做一个简单的比喻：
So many people still don't understand it, so make a simple metaphor:
假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。这只是举一个例子，小编相信小时候大家可能都想从爸爸妈妈的口袋里拿点钱来花。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。
If you had an account book in your family, you could keep it. In the past, Mom and Dad gave you their salary, so you could keep it on the books. In the middle of the day, if you wanted to eat something good, you might have 10 pieces less. This is just an example. The editor believed that when you were a kid, everyone might want to spend some money in his mother's pocket. The way to solve the problem was to use the block chain: if you did it with the whole family, there would be no problem, because you're in the books, your father is in the books, your mother is in the books, and they can see the books. You can't change them, you can't change them, you can't change them, you can't buy smoke dads 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一个区块就是一个账本它不仅能记录交易信息还有更多功能。
In other words, the distributed digital book of the block chain records every block of transactions that have occurred and that has been unanimously recognized by the system as an account book that not only records transaction information but also has more functionality.
多功能的“区块链”
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。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。
Not only can it record every transaction, but it can also be programmed to record almost all things of value to humans: birth and death certificates, marriage certificates, title deeds, degree certificates, financial accounts, medical history, insurance claims, ballot papers, food sources, and any other thing that can be coded. Each block is like a hard disk, saving all of this information and encrypting it through cryptography.
区块链系统每10分钟会检验期间产生的所有数据(比如交易记录以及该区块何时被编辑或创建的记录等)，并将这些数据储存在一个新的区块上，这个区块会与前一个区块连接，从而形成一根链条。每个区块都必须包含前一区块的相关信息才能生效。这么看来区块链拥有一些超强的技术特点。
The block chain system will test all the data generated during the 10-minute period (e.g. transaction records and when the block is edited or created) and store them on a new block, which will be connected to the previous block and thus form a chain. Each block must contain relevant information on the previous block in order to be effective.
区块链的特点
Features of the block chain
1、异常安全：不同于公司或政府机构拥有的集中化数据库，区块链不受任何人或实体的控制，数据在多台计算机上完整地复制(分发)。与集中式数据库不同，攻击者没有一个单一的入口点，数据的安全性更有保障。
Anomalous security: unlike centralized databases owned by companies or government agencies, block chains are not controlled by any person or entity, data are reproduced (distributed) in a complete manner on multiple computers. Unlike centralized databases, the attackers do not have a single entry point and the security of the data is more secure.
2、不可篡改性：一旦进入区块链，任何信息都无法更改，甚至管理员也无法修改此信息。一个东西一旦出现就再也没法改变，这种属性对于人类目前所处的可以更改、瞬息万变的网上世界而言意义重大。
II. Non-frozenness: Once you enter the block chain, no information can be changed, not even by the administrator. Once something appears, it can never change. This attribute is significant for the changing, rapidly changing online world in which human beings are currently living.
3、可访问：网络中的所有节点都可以轻松访问信息。
3. Accessible: All nodes in the network have easy access to information.
4、无第三方：因为区块链的去中心化，它可以帮助点对点交易，因此，无论您是在交易还是交换资金，都无需第三方的批准。区块链本身就是一个平台。
4. No third party: because the block chain is decentralised, it can help point-to-point transactions, so that you do not need a third party’s approval, regardless of whether you are trading or exchanging funds.
区块链的未来发展和应用场景，到底是什么样的?
What is the future of the development and application of the
1、数字身份
1, digital identity
很多人开各种证明时会遇到“证明我妈是我妈”的窘境，有了区块链，就再也不用担心了。原来我们的出生证、房产证、婚姻证等等，需要一个中心节点，大家才能承认。一旦跨国，合同和证书可能就失效了，因为缺少全球性的中心节点。区块链技术不可篡改的特性从根本上改变了这一情况，我们的出生证、房产证、婚姻证都可以在区块链上公证，变成全球都信任的东西，当然也可以轻松证明 “我妈是我妈”。
Many people come across the dilemma of proving that my mother is my mother, and with a block chain, they don't have to worry anymore. Our birth certificates, real estate certificates, marriage certificates, etc., need a central node to be recognized. Once transnational, contracts and certificates may lapse, because of the lack of a global node. The immutable nature of the block chain has fundamentally changed the situation, so that our birth certificates, real estate certificates, marriage certificates can be notarized on the block chain, become something that is globally trusted, and, of course, can easily prove that "my mother is my mother."
2、卫生保健
简单说就是利用区块链建立有时间戳的通用记录存储库，进而达到不同数据库都可提取数据信息的目的。例如你去看病，不用换个医院就反复检查，也不用为报销医保反复折腾，可以节省时间和开销。
Simply put, the block chain is used to create a time-stamped repository of common records, thereby achieving the purpose of which data can be extracted from different databases.
3、旅行消费
3, travel consumption
例如我们经常会用携程、美团等app来寻找并下单入住酒店和其他服务，各个平台从中获得提成。而区块链的应用正是除去中间商，并为服务提供商和客户创建安全、分散的方式，以达到直接进行连接和交易的目的。
For example, we often use hand-in-hand, legions, etc., to find and place single hotels and other services, from which platforms are drawn. The use of block chains is precisely to remove middlemen and to create a safe and decentralized way for service providers and customers to directly connect and trade.
4、更便捷的交易
4, easier transaction
区块链可以让支付和交易变得更高效、更便捷。区块链平台允许用户创建在满足某些条件时变为活动的智能合约，这意味着当交易双方同意满足其条件时，可以释放自动付款。
Block chains can make payments and transactions more efficient and easy. Block chain platforms allow users to create smart contracts that become active when certain conditions are met, which means that automatic payments can be released when the parties to the transaction agree to meet their conditions.
5、严把产品质量关
假如你买了一个苹果，在区块链技术下，你可以知道从果农的生产到流通环节的全过程。在这其中有政府的监管信息、有专业的检测数据、有企业的质量检验数据等等。智慧的供应链将使我们日常吃到的食物、用到的商品更加安全，让我们更加放心。
If you buy an apple, under block chain technology, you know the whole way from fruit farmers to the flow chain. Here's government regulatory information, professional testing data, quality testing data for businesses, and so on. Smart supply chains will make our daily foods, the goods we use, safer and more reassuring.
6、产权保护
6, Property Rights Protection
艺术创作者把自己的作品放在区块链上，有人使用了他的作品，他就能立刻知道。相应的版税也会自动支付给创作者。区块链技术既保护了版权，也有助于创作者更好更直接地向消费者售卖自己的作品，而不再需要发行公司的协助。
An artist puts his work on a block chain, and someone uses it, and he knows it. The corresponding royalties are paid automatically to the creator. The block chain technology protects copyrights and helps the creators sell their work better and more directly to consumers without the help of the distributors.
