May. Digital RMB does not need to rely on the network system when it makes payment. Therefore, the cost of payment will be lower. To a large extent, it may further enhance the convenience of payment and even the future universality of digital RMB. Moreover, digital RMB has the characteristics of legal compensation, that is to say, all public and private debts in our territory, any creditor, at any time, should not refuse to accept our digital currency, digital RMB, for any reason

support loose coupling of bank account

support loose coupling of bank account means that you can open a digital RMB wallet without a bank account

for some people in rural areas or remote mountainous areas, overseas tourists, etc., who can not or are inconvenient to hold bank accounts, they can also enjoy corresponding financial services through digital wallet, which is helpful to realize inclusive finance

2.

Generally, the excellent digital currencies are mostly imported procts, such as bitcoin, Leyte coin, ether coin and so on. However, the domestic Yuanbao coin, Ruitai coin, bitcoin and the tokens of different crowdfunding projects of European crowdfunding are excellent digital currencies

digital currency (English: digital currency) is an alternative currency in the form of electronic currency. At present, no central bank of any government has indicated that it will issue digital currency, and digital currency does not have to have a benchmark currency and a central bank

it is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold. Today's digital currency, such as bitcoin, lightcoin and ppcoin, is an electronic currency created, issued and circulated by check sum cryptography

3. Virtual currency ranking

the ranking of digital currency can be measured according to multiple dimensions, such as market value, technical ability, landing in Cheng, 24-hour rise and fall, 24-hour turnover list, 24-hour turnover rate, etc. For the sake of data accuracy, we list the ranking of virtual currencies in the market value list<

let's first look at the data to see how the Ministry of instry and information technology measures the value of digital currency:

saidI Research Institute of the Ministry of instry and information technology officially announced the first global public chain technology evaluation index and ranking. Eth ranked first with a total index of 129.4, while BTC only ranked 13th<

moreover, the ranking method this time is that CCID Research Institute of MIIT does not mention cryptocurrency, but only public chain. The first list of evaluation objects are: bitcoin, Ethereum, reborn, Leyte, bitcoin cash, Cardano, starcoin, Neo, eota, Monroe, dasey, Xinjing, Ethereum classic, quantum chain, Nanor, application chain Big zero coin, verge, stratis, cloud storage coin, stim coin, bitstock, byte coin, wave coin, deced, super cash hcash, Comodo coin, ark. The top ten in the list are eth, stem, LSK, Neo, KMD, XLM, ADA, iota, XmR and strat<

If ranked by market value, the results will be much different: the following data are based on Niuniu app, and the market value represents the first place at the time of writing: bitcoin (BTC)

current price: 26428 yuan, market value: 460.018 billion yuan, total amount of CDB: 21 million, circulation volume: 17.406 million, and circulation market value: 460.207 billion yuan, Issue time: 2009.01.03

second place: XRP

current price: 236 yuan, market value: 95.192 billion yuan, total issue volume: 100 billion yuan, circulation volume: 40.327 billion yuan, circulation market value: 95.181 billion yuan, issue time: 2011.04.18

third place: eth

current price: 734 yuan, market value: 76.136 billion yuan, total issue volume: 104 million yuan, Circulation volume: 104 million, circulation market value: 76.136 billion, issue time: July 24, 2014

fourth place: Star currency (XLM)

current price: 98 yuan, market value: 18.834 billion, total issue: 104.523 billion, circulation volume: 19.155 billion. Circulation market value: 188.43 yuan. Issue time: 2014.08.01

fifth place: bitcoin (BCH)

market value: RMB 137.700 billion, currency price: RMB 810.175, total currency: RMB 21 million, bitcoin cash released on August 1, 2017, jointly created by some bitcoin developers, belongs to the new version of bitcoin. From 2015 to 2017, the price of bitcoin rose rapidly. Different factions competed fiercely for more computer network resources. In order to get out of the competitive environment, one camp created another version and rebuilt the blockchain currency. Bitcoin cash modifies the code of bitcoin, increases the block size to 8m, adopts two-layer network, reces the workload of bitcoin network, and maximizes the efficiency of bitcoin network without damaging the original structure and security of bitcoin blockchain

with the integration of the two exchanges of okex and Huo yuan.com, yuanniuniu can share the trading depth and enjoy the treatment of zero handling charge fund transfer. It only needs to download an app to exchange transactions at both ends. At the same time, yuanniuniu is also a good market software tool, which can help speculators master the latest currency price trends and large positions.

4. The essence of quasi currency is decentralization, anonymity, security, open source, and so is blockchain. Because the price volatility of digital currency has always been large, it is impossible for users to put their digital currency in the centralized exchange for trading or let the centralized institution manage it on their behalf, because it is not convenient, and it also causes great security risks to users, so the virtual currency wallet developed with blockchain Technology has come into being
in the existing mainstream development enterprises, only a few of them can use the blockchain technology to develop the virtual currency related procts like Yingtang Zhongchuang, and there are many development schemes for reference.

5. [editor's note] some developers may still not understand how useful docker is to themselves, so this article will introce the use cases of docker in the development process of ordinary developers. Nowadays, docker has won a lot of attention. Many people think it is difficult to live up to its reputation because they still can't figure out the relationship between docker and ordinary developers. Many developers feel that docker is far away from themselves. Docker is a tool in the proction environment and has nothing to do with themselves. It took me a long time to figure out how to use docker in my own development as an ordinary developer. Frankly speaking, I am still in the process of learning. This article provides a list of docker use cases, which I hope will help you better understand docker and arouse your thinking. This article only describes the daily application of docker in ordinary developers, and does not provide a complete solution. Before introcing use cases, I hope you can remember this sentence: "docker is a portable application container". You may not know what docker means by "portable container", but you must know that docker can bring great efficiency improvement in daily life. When you need to run your own application (of course, any application) in the container, docker provides a basic system image as the basic system for running the application. In other words, any application on Linux system can run in docker. Can I run the database in docker? Certainly. Can I run node.js web server in docker? Certainly. Can I run API server in docker? Certainly. Docker doesn't care what your application is or does. Docker provides a set of methods for application packaging, transmission and deployment, so that you can better run any application in the container. I often use the following examples myself. Of course, you can share better examples with me. To try new software, it is necessary for developers to try all kinds of new technologies, but developers are not likely to build a good environment and test them one by one. Time is very precious. Thanks to docker, we can build the environment in one or several commands. Docker has a foolproof way to get software. The background of docker will automatically get the environment image and run the environment. It's not just about building a new technology environment to get docker. If you want to quickly run a MySQL database or a redis message queue on your laptop, you can do it very easily with docker. For example, docker only needs one command to run MySQL database: dockerrun-d-p3306:3306tutum / MySQL. Translator's note: Although MySQL database can be installed very quickly by using commands, docker is a very good choice when using the latest technology or very complex technology. For example, gitlab takes ordinary users about one day to build gitlab platform, while docker only needs one command. Now I often need to do one or two demonstrations to customers and others with my own development results on weekends. The process of building demonstration environment is very troublesome. Now I find that docker has become the most reasonable way for me to demonstrate these tools. Meanwhile, for customers as like as two peas, I can directly provide Docker images to them without having to do any work of environmental configuration, and the effect will be exactly the same as they can see in their presentation, without worrying about their environmental configuration that will cause our procts to be unable to run. Avoid "I can run on my machine." this is mentioned in both the enterprise deployment docker described in the previous article and the personal docker use case in this article. Because of the different environment configuration, many people will encounter this situation in the development, and even the developed software can not run on the tester's machine. But that's not the point. The point is that if we had a reliable and distributable standard development environment, our development would not be as painful as it is now. Docker can solve this problem. Docker image will not be unable to run because of the change of environment, nor will it have different running results on different computers. It can submit docker images containing applications to testers, so that "it can run on my machine" will no longer happen, which greatly reces the time cost of developers and testers checking machine environment settings with each other. Another area where docker can be useful is training classes. In addition to the isolation of docker container, we can realize that the advantage of docker lies in environment construction. Everyone who is new to the training class has to spend a lot of time on setting up the environment, but if docker is applied here, we just need to distribute the standard running environment image, and then we can start the class. Using docker is as simple as using virtual machine, but docker is more convenient and lightweight. At the same time, we can also tell the students: "at the same time of training, we will also learn the most popular technology - docker". This win-win outcome, why not. Learning Linux scripts may seem strange, but it's a good opportunity for people who are not familiar with Linux operating system and shell scripts. Even if this article is not about Linux, the importance of Linux is still self-evident. If you are using windows, then I give you a suggestion: rent a virtual machine from the virtual machine provider: I recommend using the virtual machine of coreos system. Although this will not let you become a professional Linux operation and maintenance, it can let you quickly learn the basic knowledge of Linux, fall in love with the command line operation, and graally start to be familiar with and appreciate Linux. To make better use of resources, the granularity of virtual machine is "virtual machine", while the granularity of docker is "restricted application". Comparatively speaking, docker occupies less memory and is more lightweight. For me, this is an advantage of docker: because I often run multiple docker applications on my own computer, using docker is simpler, more convenient and more granular than using virtual machine, and can continuously track the state of containers. If you've been following technology news, you've heard of the concept of "microservices.". Docker can be well combined with micro services. Conceptually, a microservice is a part of the function that provides a whole set of applications. Docker can always act as a container for microservices in the process of development, testing and deployment. Even the proction environment can deploy micro services in docker. Migrating between cloud service providers, most of the cloud host providers have fully supported docker. For developers, this means that you can easily switch cloud service providers, and of course, you can also easily move your local development environment to the virtual machine. There is no need to configure the local running environment and the running environment on the virtual machine once. Fully deploying docker (docker here and docker there) as a standard running environment can greatly rece the workload and generate bugs when the application is online.

6. We should be cautious. Now the platform only allows funds to enter, not to come out<
the CBRC, the Ministry of instry and information technology, the people's Bank of China and the State Administration for Instry and Commerce suggest that in recent years, in the name of "financial mutual assistance", the behavior of promising high returns and luring the public to invest funds has appeared in many places in China. Its main characteristics include: 1
first, there are many names. Common are: "XX financial mutual aid community", "XX financial mutual aid platform", "XX financial mutual aid financing", "XX charity financial mutual aid platform", "XX financial mutual aid investment", "XX mutual aid community", "XX wealth mutual aid platform", etc< Second, it develops rapidly. Relying on the Internet, through the website, blog, wechat, QQ and other platforms, the publicity has a wide range
thirdly, it is confusing. Under the banner of "overseas celebrities", some claim to "destroy the unfair world financial system, break the control of financiers, and create a community for ordinary people" as the goal. Through the establishment of the so-called "fair, just, mutually beneficial and honest financial platform for people to help others", the public can get more help by subsidizing others. At the same time, he falsely claimed that "after market test, he has been mature in many countries for many years, and has hundreds of millions of members in the world" and so on
4. Strong incement. It claims that the investment threshold is low, the cycle is short and the income is high. For example, after free registration, the investment of RMB 60000-60000 can be withdrawn after 15 days, with daily income of 1%, monthly income of 30%, annual income of 23 times, and no handling charge. In addition, if participants develop others to join, they can also get extra income such as recommendation Award (10% of offline investment) and Management Award (the corresponding proportion is determined according to the membership level). There is no upper limit for development personnel and no upper limit for rebate< 5. Strong concealment. Most of them are controlled remotely by overseas personnel, and the investment funds are often transferred through personal bank accounts or through third-party payment platforms
this kind of operation mode violates the law of value, and it is difficult to maintain the capital operation for a long time. Once the capital chain breaks, investors will face serious losses. The general public is requested to raise their awareness of risks, invest rationally and prudently, and prevent their interests from being damaged. At the same time, we can actively report to the relevant departments the clues we have learned about crimes
bitcoin home and many mainstream media have reported similar virtual money pyramid schemes.
