2. blockchain is a technology, but it is not a single technology, but the result of the integration of a variety of technologies, including cryptography, mathematics, economics, network science and so on. You can think of it as a distributed shared accounting technology, or as a database, but the database is jointly maintained by all nodes in the chain, and each node has an account book. Because the account books of all nodes are consistent, different nodes can trust each other, and there is no doubt about the data, so we all say that the blockchain has realized trust technically. For detailed professional technology, you can consult some professional technology companies, such as Jinbo technology, which focuses on the development of blockchain related procts, professional R & D team and perfect after-sales service, and you can consult by telephone.

pay attention to
it has been four days since the end of postgraate entrance examination, After a few days of natural and unrestrained time, I still want to share with you some of the process of my postgraate entrance examination. In the past half a year, many people thought that I spent most of my time on the postgraate entrance examination. In fact, I did some other interesting things. For example, in the postgraate entrance examination process, I went to participate in the computer design competition, also honored to win the national first prize, still a little proud. Now let's get down to business. Let me talk about the experience of participating in the competition As for the experience of the postgraate entrance examination, I would like to share with you after the results of the preliminary examination)

as a senior who participated in the two competitions, I want to tell you that this competition is still very routine, and once you master the routine, it is good to win the prize

about the judges and evaluation criteria of the competition: it is worth noting that the evaluation criteria of the judges of the school competition, the city competition and the national competition are slightly different, so naturally the results are also very different, but the evaluation of the school competition and the national competition are similar, and the standards of the city competition are slightly different. In fact, the author thinks that there are two main points in game planning: innovation and algorithm. In particular, the city competition pays more attention to the compilation of algorithm, while the national competition pays more attention to innovation. What's more, it's worth noting that many of the judges of the National Games are professors of the older generation, so we have to figure out how to convince the judges of the older generation that your project is very practical and important

suggestions on topic selection: I believe there are still many students who still don't know what to do or where to start, so I want to tell you that the judges of the national championship are aging, and most of them like to see some relatively new technologies and topics. So we can combine the hot technology on the market with our daily life to determine the goal of our software. For example, this year's competition software of the author is an attendance system that applies living face recognition technology and geographic information positioning to class roll call. It also uses NLP natural language processing and emotion recognition of network AI to make a comment system, which mainly solves the problems of absenteeism rate, late rate and substitute rate in our daily learning; A friend of the author also won the first prize for a system with the characteristics of blockchain, bill market and Finance University. So I still suggest that you use some new technology now, and make a useful system with a problem in your life. Remember to be new. If the topic is not new, the teacher will easily ask why I want to use your software instead of the more mature software on the market

about how to learn and choose novel technology: the author here can provide you with some relatively novel technology websites for you to consider, and there are many ready-made APIs for you to consider. 1. Internet AI, website: http://ai..com/ 2. Tencent AI, website: https://ai.qq.com/ 3. Ethereum, website: https://ethfans.org/ 4. Turing robot, website: http://biz.turingos.cn/home 5. Tencent big data platform, website: https://data.qq.com/ 6. Knowledge workshop, website: http://kw.fudan.e.cn/ . Readers recommend that you consider the knowledge workshop. After all, knowledge mapping is a hot topic, which can be well applied to practical projects, and it can be done in a dazzling way. Few people who participate in the competition use knowledge mapping, which is a relatively new technology

about team division: This is a very important point. Because the general project team has three people, so in my opinion, the best match is a front-end, a back-end, a dedicated document writing Document writing is really troublesome)

front end: if you participate in the design of the web site, the author's suggestion is that you should at least use a simple version of the mobile terminal, because in the first year of the competition, the author was asked: now is the era of mobile Internet, your idea of this project is OK, but it's too troublesome to use. So the next year, the author made a mobile terminal (small program), and the judges didn't say that we were inconvenient to use. For the proction of mobile terminal, the author's suggestion is to make a small program, because the small program is really easy to learn, and the code is very similar to HTML, CSS and JavaScript. It's very simple. The key is that its advantage is that it is suitable for both Android and IOS App learning website: https://developers.weixin.qq.com/miniprogram/dev/index.html

back end: I suggest you still use the framework to write code, because it's really convenient to use the framework. Many predecessors have written a lot of very useful interfaces in advance, such as the storage of pictures, videos, etc., if you use the native code to write, If you don't use the cache, it will run very slowly, but if you use the framework, there won't be such a problem, because the predecessors have designed excellent ready-made interfaces for you to use, and you can learn from the source code they wrote when you have time. The most important thing is that the enterprise recruits people who can use the framework. Of course, I'm not saying that the original is not good. The original is an internal skill, and we should pay attention to it. However, there may be some problems in the learning of framework at the beginning, but I believe you can solve this problem very well! Here I recommend you to learn several frameworks: ThinkPHP, Django, springboot. The first two are relatively easy to learn, which are PHP and python frameworks, while the latter one is relatively difficult, which is Java. For those who want to learn crawler, they can learn Django, because it is very similar to the crawler framework scrapy, which is easy to master at the same time. It is said that Django and scrapy are developed by the same development team, so they are very similar. Of course, I just heard that I don't know what the actual situation is, hahaha

documents: the preparation of documents is really cumbersome, because there are many documents, so it's better to have a special person to write documents, especially to be able to build UML diagrams, mind maps and so on. When writing a document, you must pay attention to the time node. If you miss the time node, it's a pity

about programming language learning: I believe many students can't find a better programming language or framework learning website at present. Here I recommend several websites that I think are better: 1. MOOCS website, website: https://www.imooc.com/ 2. Laboratory building, website: https://www.shiyanlou.com/ 3. MOOC of China, website: https://www.icourse163.org/ 4. CSDN, website: https://www.csdn.net/ 5. GitHub, website: https://github.com/ . Now, we need to buy money in the Mogao class network and the experimental building. We need to buy money now. It's more expensive. You can go to salty fish and turn around to find a screen lesson. A treasure has been forced by some treasure official account. Of course, if you really can't find it, you can ask me some frames of learning videos in the background of public numbers. I still have some video stock of courses. The disadvantage of Chinese MOOCS lies in its timeliness. It can't be seen after the learning time of the course. It may be to protect teachers' rights and interests of knowledge labor. CSDN is very important. For beginners, CSDN should be able to cover all your problems. GitHub, as we all know, is mainly used to search for ready-made projects to learn other people's ideas of building software, or to search for some useful plug-ins, such as IP agent pool and fake user agent, which are commonly used in crawlers.

Digital asset wallets include imtoken, bitpai, Kushen, Hufu and so on. Let's talk about it in detail:

when it comes to blockchain digital assets, you can't do without digital wallets. With the continuous development of blockchain technology, digital wallets play an increasingly important role in the blockchain ecology. In the early days, only basic functions such as transfer, storage, and collection were available, Nowadays, digital wallet can not only manage assets, but also manage financial affairs, trade digital assets and guide DAPP of public chain< digital wallet has become an important entry into the blockchain world

we often hear about hot wallets, cold wallets and hardware wallets. What's the difference between them? According to different standards, digital wallets can be classified in different ways. Let's talk about several common classification methods of digital wallets

03 according to the degree of decentralization of wallets, digital wallets can be divided into full node wallets, light node wallets and centralized wallets

all node wallet refers to the wallet that synchronizes all data on the blockchain . For example, bitcoin's all node data has reached several hundred gigabytes. Bitcoin's all node wallet needs to synchronize all data. Although the all node wallet occupies a large storage space, it can achieve complete decentralization

the light node wallet relies on other full node wallets on the blockchain and only synchronizes its own related data, thus realizing partial decentralization for example, our commonly used bitcoin wallets are light node wallets. When using these wallets, it is unrealistic to download only data related to our own bitcoin account, and it is also unrealistic to download hundreds of gigabytes of data

centralized wallet means that all data are obtained from its own centralized server , and the data depends on the wallet service provider's own account book. Its transaction efficiency is very high, and it can basically achieve real-time account arrival. For example, our wallet in the transaction platform is a centralized wallet
