“区块链”到底是啥
What the hell is a 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。
From an academic point of view, block chains are new applications of computer technology such as distributed data storage, point-to-point transmission, consensus mechanisms, encryption algorithms, etc.
区块链本质上是一个去中心化的数据库。
The block chain is essentially a decentralised database.
这么解释
That's an explanation.
很多人还是看不懂
A lot of people still don't understand.
那么小编做一个简单的比喻
So the editor makes a simple metaphor.
假设环境：
Assumption environment:
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。
If you had an account book in your house, you'd keep it. In the past, Mom and Dad gave it to you, so you could put it on the ledger. In the middle of the day, if you wanted to eat something good, maybe you'd have a dozen pieces less. That's just one example, the editor believed that when you were a kid, everyone might want to spend some money from Mom and Dad's pocket.
用区块链解决问题的方法：
The way to solve the problem using a block chain:
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 the whole family were to be mobilized, the problem would not be the same, because you're taking the books, your father is taking the books, your mother is taking the books, they can see the books, you can't change them, you can't change them, you can't change them, you can't buy them, you can't buy them and you can't eat them.
也就是说，区块链
In other words, the chain of blocks.
这个分布式的数字账本
This distributed digital account book
记录了所有曾经发生
It's a record of everything that's ever happened.
并经过系统一致认可的交易
And it's a system-sanctioned transaction.
每一个区块就是一个账本
Each block is a book of accounts.
它不仅能记录交易信息
It doesn't just record transactions.
还有更多功能
There's more to it.
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.
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。
Each block is like a hard disk, saving all of this information and encrypting it through cryptography. The stored information cannot be tampered with.
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。
The block chain system will test all data generated during the period (e.g. transaction records and when the block is edited or created) every 10 minutes 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 valid.
这么看来
That's what it looks like.
区块链拥有一些超强的技术特点
The block chain has some super-technical features.
区块链的特点
Features of block chains
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
Future development and application of the block chain
到底是什么样的？
What was it like?
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。
A lot of people get in the position of “prove my mother” when they write all kinds of certificates, and when they have a block chain, they don't have to worry about it anymore.
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。
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.
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”。
The immutable nature of block chain technology has fundamentally changed this situation, and our birth certificates, real estate certificates, marriage certificates can be notarized on block chains, become globally trusted things, and can easily prove that "my mother is my mother."
2、卫生保健
2. Health
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 transactions
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
5. Tighten the quality of the product
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. Protection of property rights
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.
