区块链起源于中本聪的比特币，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。标志着上轮金融危机起点的雷曼兄弟倒闭后两周，2008年11月1日，一位自称中本聪的人发表了《比特币:一种点对点的电子现金系统》一文，阐述了基于P2P网络技术、加密技术、时间戳技术、区块链技术等的电子现金系统的构架理念，这标志着比特币的诞生。两个月后理论步入实践，2009年1月3日第一个序号为0的比特币创世区块诞生。几天后2009年1月9日出现序号为1的区块，并与序号为0的创世区块相连接形成了链，标志着区块链的诞生。
originated in a decentralised database, essentially a decentralised database. , which in essence marks the birth of a digital cash system based on P2P network technology, encryption technology, time-stamp technology, block-chain technology, etc. This marks the birth of a bitcoin. Two months later the theoretical step is followed by the birth of a zero-bit coin-breaking block on 3 January 2009.
区块链公司 155---0116---2665 近年来，世界对比特币的态度起起落落，但对区块链技术的关注度越来越高。在比特币形成过程中，区块是一个一个的存储单元，记录了一定时间内各个区块节点全部的交流信息。各个区块之间通过随机散列(也称哈希算法)实现链接(chain，后一个区块包含前一个区块的哈希值，随着信息交流的扩大，一个区块与一个区块相继接续，形成的结果就叫区块链。
& nbsp; & nbsp; block chain & nbsp; 155 - 0116 - 2665 & nbsp; in recent years, the attitude of the world's Bitcoin has risen and fell, but there has been increasing interest in block chain technology. During Bitcoin formation, blocks are a storage unit that records the full exchange of information by block nodes over time. As the exchange of information expands, one block is called the chain as it follows one block.
通俗一点说，区块链技术就指一种众人参与记账的方式。所有的系统背后都有一个数据库作为载体，可以把数据库看成是就是一个大账本。那么谁来记这个账本就变得很重要。目前就是谁的系统谁来记账，微信的账本就是腾讯在记，淘宝的账本就是阿里在记。但现在区块链系统中，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，系统里面的其他人也可以将这段时间内的消息记录进行备份，系统中的每个人可以查到完整信息的。
It is common to say that block chain technology refers to a way in which people are involved in bookkeeping. There is a database behind all systems as a vehicle that can be seen as a large account book. It becomes important who keeps this account book. Who's the one who's in the system at the moment, the notebook is in the system, and Ali is in the book. But now everyone in the system has an opportunity to be involved in bookkeeping. If there is any change in data in the system for a certain period of time, everyone in the system can record the account, and the system will judge the fastest and best person in the period of time, write the contents of his records into the account book, and others in the system can copy the information records for that period, and everyone in the system can find complete information.
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，是对所有比特币交易历史的记录。比特币的交易数据被打包到一个“数据块”或 “区块”(block)中后，交易就算初步确认了。当区块链接到前一个区块之后，交易会得到进一步的确认。在连续得到6个区块确认之后，这笔交易基本上就不可逆转地得到确认了。
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 recording the history of all bitcoin transactions. After Bitcoin transactions are packaged into a “data block” or “block” (block), the transaction is initially confirmed. When blocks are linked to the previous block, the transaction is further confirmed. After six consecutive blocks are confirmed, the transaction is essentially irreversibly confirmed.
区块链在网络上是公开的，可以在每一个离线比特币钱包数据中查询。轻量级比特币钱包使用在线确认，即不会下载区块链数据到设备存储中。
The block chain is publicly available on the network and can be consulted in every offline bitcoin wallet data.
从区块链的形成过程看，区块链技术具有以下特点。
From the process of forming the block chain, the block chain technology has the following characteristics.
一是去中心化。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。
The first is decentralization. Block chain technology is not dependent on additional third-party management or hardware facilities, has no central control, and apart from the self-contained block chain itself, through distributed accounting and storage, the information is self-validated, transmitted and managed at all nodes. Decentralized is the most prominent feature of the block chain.
二是开放性。区块链技术基础是开源的，除了交易各方的私有信心被加密外，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开放的。
The second is openness. The technical basis of the block chain is open-source, and the data in the block chain are open to everyone, with the exception of the confidence of the parties to the transaction that it is encrypted, and anyone can access the block chain data and develop relevant applications through open interfaces, so that the information throughout the system is highly transparent and open.
三是独立性。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。
Third is independence. On the basis of 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.
四是安全性。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。
The fourth is security. As long as 51% of all data nodes are not controlled, network data cannot be manipulated arbitrarily, making the blocks themselves relatively secure and avoiding subjective data changes.
五是匿名性。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。
The fifth is anonymity. Unless there is a legal norm to do so, the identity information of each block node does not technically need to be disclosed or authenticated, and the information may be transmitted anonymously.
区块链的发展趋势是全球性的。英国已经把区块链列为了国家战略，新加坡央行在2015年就已经支持了一个基于区块链的记录系统，日本目前在区块链领域也处于领先地位。R3CEV作为首个以创建分布式账本应用为目标而成立的商业联盟，目前在全世界范围内拥有包括花旗、摩根、富国、渣打等50多位成员。
The UK has included block chains as a national strategy, the Central Bank of Singapore has supported a block chain-based record system in 2015, and Japan is now in the lead in the block chain area. R3CEV, the first commercial alliance set up with the goal of creating distributed book applications, currently has more than 50 members worldwide, including flag, Morgan, rich countries, scum, etc.
而国内目前已成立了中国分布式总账基础协议联盟、中国区块链应用研究中心、金融区块链联盟等，以推动区块链产业研究与合作。继区块链被正式列入“十三五”国家信息化规划，区块链技术研究已然处于最好的触发点。
In China, a coalition of China’s basic master-account agreements, the China Centre for Applied Research in Block Chains, and the Financial Block Chain Alliance have been established to promote research and cooperation in block chain industries. The chain of blocks is officially included in the 13th Five-Year Plan for Informatization, and the technical study of the block chain is at its best trigger point.
然而目前国内的区块链创业项目基本还处于研究设想、小范围试验阶段，少有成型的商业模式，缺乏正式机构组织的推动。因此，建立大而强的联合体，推动并提高我国区块链技术领域的研究、应用和开发水平，促使我国相关产业走出去，在新一轮国际竞争中抢占技术标准和专利的制高点和话语权，将是未来我国在区块链技术领域的着重发力点。
However, the country’s block chain entrepreneurship project is still largely at the stage of research, small-scale pilot projects, few business models and lack of formal institutional organization. Therefore, the creation of a large and strong consortium to promote and enhance the level of research, application and development in the technical field of the block chain in our country, prompting the relevant industries to move out and seize technical standards and patents in the new round of international competition, with high-levels and voice rights, will be our future focus in the technical field of the block chain.
