区块链到底是什么？一分钟看懂

2w刀/枚比特币？4.0互联网时代的革命性技术区块链？

2w knife/bitcoin? 4.0 Internet-era revolutionary technological blocks?

这两个突然爆火的名词真有这么厉害？它到底是个什么？

These two sudden fires are so powerful. What the hell is it?

理解区块链一句话：

understands a phrase from the block chain:

一个去中心化的分布式记账技术。

A decentralised distributed bookkeeping technique.

先了解什么是去中心化:

其实很简单，在过去，集中就像媒人介绍的相亲，或者中间的红绳老了。

In fact, in the past, concentration was like a matchmaking match or a red rope in the middle.

分散就是自由恋爱，然后结婚。

Fragmentation is free love and then marriage.

什么是分布式账簿：

What's a distributed book:

过去，每个人的生日八字和夫妻关系都只记在媒人或月老有了区块链技术，村里的科技发展迅速，每个家庭都有一本网络小本，每个人都可以记录村民结婚的信息。

In the past, every person's birthday and marital relationship had only been recorded in the media or in menstrual age with block-link technology, the technology in the village was growing rapidly, every family had a small web book, and everyone could record information about the villagers' marriage.

不能更改数据：

Unable to change data:

几天后，贵生的前女友雪莲，突然跳了出来，哭了起来，只是不相信贵生结婚了。这时，村里的其他人会好心劝她:姑娘，别傻了！

A few days later, your ex-girlfriend, Snow Lotus, jumped out and cried, but didn't believe you were married. At that point, the rest of the village would be nice to her: girl, don't be silly!

区块链技术也是如此。如果黑客想修改数据，除非他能修改51%村民的数据，否则：别傻了！因此，区块链的数据稳定性和可靠性极高。

The same is true of block chain technology. If hackers want to change the data, unless he can change 51% of the villagers' data: Don't be silly! Therefore, the data stability and reliability of the block chain are extremely high.

媒人和月老是中心；

Media and menstruation are centres;

公布结婚消息称为广播；

(b) The publication of the marriage information, known as the radio;

每个家庭，相当于一个分布在村里各个地方的网络账本，形成一个完整的分布式账本网络；

Each family, equivalent to a web-based account book distributed throughout the village, forms a fully distributed network of accounts;

村民们跑去告诉结婚消息，就是数据块的传递，直到最后一个朋友得到消息，完成数据备份。

The villagers went to tell the marriage story about the transfer of the data block until the last friend received the information and completed the backup of the data.

1、去中心化（第三方不需要信用背书）

1.

由于使用分布式存储和公开透明算法，不存在，也不需要第三方集中平台，每个人的权利和义务都是平等的，

As a result of the use of distributed storage and open transparency algorithms, which do not exist and do not require a centralized platform of third parties, everyone has equal rights and obligations,

2、不得篡改信息

2. must not tamper with information

集中记账虽然有效，但有可能被修改，比如银行记录有可能被修改。

While the centralization of accounts is valid, it may be modified, for example in the case of bank records.

在区块链中，一旦信息被验证并添加到区块链中，它将永久存储，信息数据将由所有人共同记录，每个人都有整个数据库的完整备份。

In the block chain, once the information is verified and added to the block chain, it will be permanently stored, the information data will be recorded jointly by all, each with a complete backup of the entire database.

3、透明信高度开放

3. Transparency is highly open

系统是开放的。除了加密交易方的私人信息外，区块链数据还向所有人披露。任何人都可以通过公共接口查询区块链数据并开发相关应用程序，因此整个系统信息高度透明。

The system is open. Block chain data are disclosed to everyone, in addition to private information about encrypted traders. Anyone can access block chain data and develop related applications through a public interface, thus making information throughout the system highly transparent.

1、效率过低

1. is inefficient

虽然分散化有很多好处，但每笔交易都应该记录在所有用户的账簿中，这将降低效率。信息量越大，参与者越多，性能问题就会随之而来。

While there are many benefits of decentralization, each transaction should be recorded in the books of all users, which reduces efficiency. The greater the volume of information, the greater the number of participants, the attendant performance problems.

2、不得篡改、撤销

2. may not be tampered with or revoked

一旦信息输入错误，就不可能改变，这不仅防止了篡改，也是一个缺点。

Once the information is entered wrong, it is impossible to change, not only to prevent tampering, but also to make a disadvantage.

3、交易账簿必须公开

3.

由于其所有的交易都是公开透明的，那么村头二狗子买了根腊肠，甚至买了条花裤衩，我也要把它写在本子上。

Because all of its transactions are open and transparent, the village son of a bitch buys a sausage and even a pair of flowers, which I will write on the book.

区块链技术的前景：

The future of block chain technology:

结合上述优缺点，区块链、数据篡改、永久保存等良好会计特点，在供应链金融（仓单、票据、应收账款）、医疗证明、股权交易、供应链可追溯性、保险（意外保险、互助保险）、公证（公益慈善、版权）等领域非常有前途，不适合在一些高效场景中使用。

In the context of these advantages and disadvantages, good accounting features, such as block chains, data manipulation and permanent preservation, are very promising in the areas of supply chain finance (ware receipt, notes, receivables), medical certification, equity trading, supply chain traceability, insurance (unforeseen insurance, mutual insurance), notarization (public good, copyright) and are not suitable for use in some efficient scenarios.

基于区块链技术的特性，其在金融领域的应用前景相当大。

Based on the characteristics of block chain technology, its application in the financial field is promising.

以区块链为底层技术实现比特币等数字货币。比特币的最高价值超过2w美元/枚比特币的普及在很大程度上推动了区块链技术的全球讨论。

The use of block chains as bottom-line technologies to achieve digital currencies such as bitcoins. The spread of bitcoins with a maximum value of more than $2w/bitcoins has contributed significantly to the global discussion of block chain technologies.

以上是对区块链技术的一些介绍。技术层面没有太多描述，主要集中在概念解释和应用前景上。更多区块链最新消息，请继续关注其金融。
