区块链未来可能在哪些领域直接影响到我们普通人的生活呢？
& nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; in which areas could the future of the block chain directly affect the lives of our ordinary people?
数字货币
digital currency
如果你对区块链有过了解，你可能听说过比特币、以太坊等项目。这些区块链项目上都有自己发行的代币，但是都没有被世界上的任何国家所承认。那么有没有主权国家以国家信用为基础，发行一款国家数字货币呢？关于这个方面，我国走在了世界的前列。2014年，中国人民银行就开始对法定数字货币展开研究。2017年底，经国务院批准，中国人民银行组织部分商业银行和有关机构共同开展数字人民币体系（DC/EP）的研发。根据公开资料显示，数字人民币将先行在深圳、苏州、雄安新区、成都以及未来的冬奥场景进行封闭试点测试。
If you know the block chain, you may have heard of projects such as Bitcoin and Etheria. These projects have their own tokens, but they are not recognized by any country in the world. Is there a sovereign country that issues a national digital currency based on national credit? We are in the forefront of the world in this regard. , the People's Bank of China began researching the legal digital currency. , with the approval of the State Council, a number of commercial banks and related institutions of the People's Bank of China jointly developed the digital currency system ( DC/EP).
数字人民币和我们现在常用的微信、支付宝里的钱有什么区别？简单来说，央行数字货币就是纸币的数字形式，它保留了纸币的一些特点比如便携和匿名。在使用时，只要两个人都有数字钱包，手机都有电，那么不用网络可以完成两个手机间的转账或者支付，跟使用纸币非常类似。而微信或者支付宝，只是一种支付方式，并且需要严格的绑定账户，并不能满足民众便携和匿名支付的需求。
What's the difference between the digital renminbi and the amount of money in the micro-letters and payment treasures that we now use? To put it simply, the central bank's digital currency is the digital form of paper currency, which retains some of the features of paper money, such as port and anonymity. When it is used, as long as two people have digital wallets and mobile phones have electricity, it is very similar to the use of banknotes to make transfers or payments between two mobile phones without the Internet.
目前，瑞典、法国、韩国等许多国家已经公布了其央行数字货币测试计划或方案。
Currently, many countries, including Sweden, France and Korea, have published their central bank digital currency testing plans or programmes.
身份认证
ID
你有没有遇到过想要赶紧验票乘坐火车，却忽然发现没有带身份证的尴尬经历？你每次新下载一个应用或者登录一个网站，它都要求你去注册一个新账号，是不是不胜其扰？这时如果有一个身份信息区块链的话，基于区块链技术带来的高可靠性、可追溯和可协作等特性，上面的诸多问题都可以很方便地解决了。
Have you ever experienced an awkward experience when you wanted to get a ticket on a train without an I.D.? Every time you download a new application or log on a website, do you ask you to register a new account? If you have an I.D. block chain, many of the problems can be resolved easily, based on the high reliability, traceability and collaboration of block chain technology.
在这条区块链上，每个人都有一个数字身份证。针对每一个身份证，都对应着一个私钥，这个私钥由个人保管。有了数字身份证，以后无论你是坐高铁、寄快递，还是住酒店、开公司。你不用担心身份证没带或者消磁，也不用担心你的身份证被他人捡了之后去做坏事。因为私钥在你手里，每次使用身份证都需要你提供私钥来授权才可以。
On this block chain, each person has a digital identity card. For each identity card, it corresponds to a private key, which is held by a person. With a digital identity card, you'll be in a hotel, a hotel, and a company. You don't have to worry about not taking the identity card or dismigrating it or doing anything bad when someone picks it up. Because each time you have the key, you need a private key to authorize it.
目前，北京市依托区块链技术的“减证便民”行动已经开始展开，贵阳、云南玉溪和重庆等地方政府也分别通过打造“网络身份链凭证中心”等方式加快推进区块链在便民服务方面的应用。
Currently, a project to “assist people” in the technology of the Ito block chain has begun in Beijing, and local governments such as Guiyang, Yunnam Yui Creek and Chongqing have accelerated the application of the block chain in the service of the people, including through the creation of a “network-based identification chain voucher centre”.
溯源防伪
strong >
食品安全一直都是我们关心的大事，曾经“毒奶粉”、“苏丹红炸鸡腿”的新闻令人担忧，那么，区块链技术有没有可能在食品安全溯源方面做些什么？
Food security has always been a major concern for us, and the news of the “tox powder” and the “Sudanese red fried chicken legs” is worrying. Is there any way that the block chain technology can be used to trace food safety?
在没有区块链以前，传统的物联网手段虽然可以做到对产品的溯源，但是区块链技术的到来可以帮助信息在流转过程中不被篡改，起到了增信的作用。以顺丰推出的“步步鸡”为例，怎么证明一只鸡是纯正的生态土鸡？通过传感器，养鸡场的环境和鸡们的生活情况（比如吃的食材，每日步数等）都会自动将数据上传到区块链。后来这只鸡经过处理并运送到消费者的面前。这其中所有的数据，消费者都可以从区块链上查询。
In the absence of a block chain, traditional means of networking, although it can be traced back to the product, the advent of block chain technology can help to keep the information from being tampered with during the flow. How can it be proved that a chicken is a pure ecological rooster, for example? Through sensors, the environment of the chicken farm and the living conditions of the chickens (e.g. food, daily steps, etc.) automatically upload the data to the block chain. The chicken is processed and transported to the consumer. All of the data is accessible to consumers.
目前基于区块链的溯源体系已经开始逐步发展，比如阿里巴巴和五常市政府合作为五常大米溯源而建立了从生产到消费全链路的溯源体系，相信随着区块链技术在溯源领域的深入扩展，人们将可以更加放心的购买到安全合格的产品。
