什么是区块链？
区块链本质上是一个去中心化的数据库。是指通过去中心化和去信任的方式集体维护一个可靠数据库的技术方案。
The block chain is essentially a decentralised database. It refers to a technical programme of collective maintenance of a reliable database through decentralisation and detrust.
区块链技术是一种不依赖第三方、通过自身分布式节点进行网络数据的存储、验证、传递和交流的一种技术方案。因此，有人从金融会计的角度，把区块链技术看成是一种分布式开放性去中心化的大型网络记账薄，任何人任何时间都可以采用相同的技术标准加入自己的信息，延伸区块链，持续满足各种需求带来的数据录入需要。
Block chain technology is a technology that does not rely on third parties for the storage, validation, transmission and exchange of network data through its own distributed nodes. Thus, from the point of view of financial accounting, block chain technology is seen as a distributed, open, decentralised, large network bookbook where anyone can use the same technical criteria to include their information at any given time, extend the block chain and continuously meet the data entry needs arising from various needs.
通俗一点说，区块链技术就指一种全民参与记账的方式。所有的系统背后都有一个数据库，可以把数据库看成是一个大账本。在区块链系统中，系统中的每个人都可以有机会参与记账。在一定时间段内如果有任何数据变化，系统中每个人都可以来进行记账，系统会评判这段时间内记账最快最好的人，把他记录的内容写到账本，并将这段时间内账本内容发给系统内所有的其他人进行备份。这样系统中的每个人都了一本完整的账本。这种方式，我们就称它为区块链技术。
In general, block chain technology refers to a way of recording accounts with universal participation. All systems have a database that can be seen as a large book of accounts. In block chain systems, everyone in the system has the opportunity to be involved in bookkeeping. If there is any change in data, everyone in the system can come to bookkeeping for a certain period of time, and the system will judge the fastest and best person in the period of time, write the contents of his records into the books, and send them back to all others in the system. In this way, everyone in the system has a complete book of accounts. In this way, we call it the block chain technology.
区块链技术被认为是互联网发明以来最具颠覆性的技术创新，它依靠密码学和数学巧妙的分布式算法，在无法建立信任关系的互联网上，无需借助任何第三方中心的介入就可以使参与者达成共识，以极低的成本解决了信任与价值的可靠传递难题。
Block chain technology is considered to be the most disruptive technological innovation since the Internet was invented, relying on cryptography and mathematically sophisticated distribution algorithms. On the Internet, where confidence-building is not possible, consensus can be achieved without the involvement of any third-party centre, resolving the challenge of reliable transmission of trust and value at very low cost.
区块链在持续延长，而且新区块一旦加入到区块链中，就不会再被移走。区块链实际上是一群分散的用户端节点，并由所有参与者组成的分布式数据库。
The block chain is continuously extended and once added to the block chain it will not be removed. The block chain is in fact a decentralized user endpoint with a distributed database of all participants.
区块链的特征
从区块链的形成过程看，区块链技术具有以下特征：
From the process of forming the block chain, the block chain technology has the following characteristics:
一、去中心化。区块链技术不依赖额外的第三方管理机构或硬件设施，没有中心管制，除了自成一体的区块链本身，通过分布式核算和存储，各个节点实现了信息自我验证、传递和管理。去中心化是区块链最突出最本质的特征。
(i) Decentralization. Block chain technology is not dependent on additional third-party management or hardware facilities; there is no central control; apart from the self-contained block chain itself, information self-validation, transmission and management are achieved at all nodes through distributed accounting and storage. Decentralization is the most prominent feature of the block chain.
二、开放性。区块链技术基础是开源的，除了交易各方的私有信息被加密外，区块链的数据对所有人开放，任何人都可以通过公开的接口查询区块链数据和开发相关应用，因此整个系统信息高度透明。
ii. Openness. The technical basis of the block chain is open-source, with data on the block chain open to all except private information of the parties to the transaction being encrypted, and anyone can access the block chain data and develop relevant applications through open interfaces, thus providing a high degree of transparency of information throughout the system.
三、独立性。基于协商一致的规范和协议（类似比特币采用的哈希算法等各种数学算法），整个区块链系统不依赖其他第三方，所有节点能够在系统内自动安全地验证、交换数据，不需要任何人为的干预。
III. Independence. Based on consensus norms and agreements (a variety of mathematical algorithms, such as the Hashi algorithm used in Bitcoin), the whole block chain system is not dependent on other third parties, and all nodes can automatically and safely validate and exchange data within the system without intervention by anyone.
四、安全性。只要不能掌控全部数据节点的51%，就无法肆意操控修改网络数据，这使区块链本身变得相对安全，避免了主观人为的数据变更。
IV. Security. As long as 51% of all data nodes are not controlled, network data cannot be manipulated arbitrarily, making the block chain itself relatively secure and avoiding subjective data changes.
五、匿名性。除非有法律规范要求，单从技术上来讲，各区块节点的身份信息不需要公开或验证，信息传递可以匿名进行。
Anonymity. Except as required by law, the identity information of each block node is not technically required to be published or authenticated, and the transmission of the information may be anonymous.
