Zhejiang University blockchain
this has also aroused many questions, such as whether students will inlge in "speculation" after taking this course
blockchain technology is a way to make all participants in the system work together to record and maintain a reliable data log, which is more stable, more secure and more efficient, without mutual trust. The application of blockchain technology is not only in banking, but also in manufacturing, Internet of things, insurance and so on
according to the relevant statistics, the global demand for blockchain talents showed an explosive growth from 2016 to 2017. The demand for blockchain talents in computer software instry and financial instry is increasing. At present, a number of central banks or financial regulators, top consulting companies or investment banks around the world have said that blockchain is the main promising project in the field of financial technology in the future. But at present, its proportion in the total demand of the global talent market is still very low
blockchain course is nothing new in foreign countries. Many universities have opened blockchain courses. As a matter of fact, the purpose of the courses offered by colleges and universities is to cultivate useful talents in society, not to look at people's faces. In recent years, China's ecation structure is unbalanced and unreasonable, and the talent training of many universities does not meet the social needs, resulting in the disconnection between learning and application
today, the application prospect of block chain has been proved to be very broad. What's more, although there are some bubbles in the domestic chain, there is nothing wrong with opening block chain courses in universities. p>
a survey shows that among the parents of the students interviewed, 62% of them think that the university teaching, curriculum and social derailment are the biggest drawbacks of the University at present. There is a serious phenomenon of assimilation in major setting and homogenization of talents. In those years, many colleges and universities set up such unpopular majors as nanny major and electronic competition major. At first, people didn't understand them, but practice has proved that they need them. For example, the major of E-sports was once known as the major of playing games. Who would have expected that it has indeed cultivated the "talent of playing games" needed by the country, and has become a "sweet cake"
Therefore, it is not necessary for colleges and universities to be timid in specialty and curriculum setting, but to actively integrate with the development of the times, connect with the market demand, scientifically set up specialties, and make efforts to cultivate competitive talents(1) distributed ledger, that is, transaction bookkeeping is completed by multiple nodes distributed in different places, and each node records complete accounts, so they can participate in monitoring the legitimacy of transactions, At the same time, they can testify together
different from traditional distributed storage, the uniqueness of distributed storage of blockchain is mainly reflected in two aspects: one is that each node of blockchain stores complete data according to block chain structure, while traditional distributed storage generally stores data in multiple copies according to certain rules. Second, the storage of each node in the blockchain is independent and has the same status, which relies on the consensus mechanism to ensure the consistency of storage, while the traditional distributed storage generally synchronizes data from the central node to other backup nodes[ 8]
no single node can record the account data separately, so as to avoid the possibility that a single bookkeeper is controlled or bribed to record false accounts. In theory, unless all the nodes are destroyed, the accounts will not be lost, so as to ensure the security of the account data
(2) asymmetric encryption and authorization technology, the transaction information stored on the blockchain is public, but the account identity information is highly encrypted, which can only be accessed under the authorization of the data owner, thus ensuring the data security and personal privacy
(3) consensus mechanism is how to reach a consensus among all accounting nodes to determine the validity of a record, which is not only a means of identification, but also a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and achieve a balance between efficiency and security
the consensus mechanism of blockchain has the characteristics of "the minority is subordinate to the majority" and "everyone is equal", in which "the minority is subordinate to the majority" does not completely refer to the number of nodes, but also can be the computing power, the number of shares or other characteristics that can be compared by computers“ "Everyone is equal" means that when the nodes meet the conditions, all nodes have the right to put forward the consensus results first, and then directly recognized by other nodes, and finally may become the final consensus results. Taking bitcoin as an example, the workload proof is adopted. Only when more than 51% of the accounting nodes in the whole network are controlled can a nonexistent record be forged. When there are enough nodes in the blockchain, this is basically impossible, thus eliminating the possibility of fraud.
(4) smart contract, which is based on these trusted and tamperable data, can automatically execute some pre-defined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and reliable, it is easy to carry out automatic claim settlement in some standardized insurance procts
Blockchain is the general trend of the tuyere project, but when choosing blockchain projects, we must shine our eyes and find a team with technology, application and real down-to-earth work. Otherwise, it may come to nothing, because since it is a trend, naturally there are a lot of speculation and fraud projects
here, we mainly introce utispace, the first blockchain distributed storage project with perfect technology and real application in the world
investment highlights
a brief introction to utispace: is 5g coming? Have big data, artificial intelligence, wearable devices, Internet of things and AI entered our lives? Is the phone running out of memory
stuck
the high-speed information flow inevitably needs infinite storage space, but the current storage space is never enough
for example, the storage space of 4G mobile phone determines the price of mobile phone, but what about 5g mobile phone? More to 10 times the demand for 4G space storage, the price will be expensive
where there is demand, there is market. In the past, we need to build a big data storage base station for big data storage. The cost is very high. It costs 10 billion yuan at any time, and the security is very low (the base station will be hot and prone to fire and earthquake, what should we do? If hackers attack all data, they will be paralyzed). In addition, no matter how big the base station is, its storage capacity is limited, and it can never meet the demand of doubling the amount of data generated by the market, resulting in a large number of useful data homeless. At present, 67% of the data has been deleted, which is a great loss
so who can solve the data storage with large storage, high security, low cost and low energy consumption
today, the decentralized distributed storage space of China's own brand utispace, together with the digital pulse chain Laboratory of Zhejiang University, has solved this worldwide problem. Thus, it takes the lead in occupying the big cake of distributed data storage
The current hot area of blockchain entrepreneurship also attracts the participation of domestic universities. Yesterday, the reporter learned from Zhejiang University that the school of computer science and the school of software of Zhejiang University will set up a course called "blockchain and digital currency" for some senior undergraates and postgraates this autumn. It is reported that this is the first university in China to offer such courses
according to media reports, more than 10 universities in the United States, including Carnegie Mellon University and Massachusetts Institute of technology, have offered courses related to digital currency and blockchain technology for students
Xiong Bingqi, an ecation expert, believes that colleges and universities should keep up with the social hot spots and adjust their courses, which will help to promote the connection between colleges and universities, students and the outside world and cultivate competitive talents. At the same time, blockchain related courses should pay attention to the scientificity of textbook compilation and the systematicness of teaching, so as to avoid becoming a gimmickZhejiang University will set up a course named "blockchain and digital assets" for some senior undergraates and postgraates in the autumn semester of 2018
in April this year, China's first 10 billion yuan blockchain innovation fund was established in Hangzhou. According to incomplete statistics, Hangzhou has 193 blockchain patents

2. Teachers. First of all, the soft college is not a tutorial system. Although it is said that there will be tutors, take the soft major of China Mobile. There are three teachers and more than 100 students... So, tutors really don't have much meaning. As for the environment of the laboratory, I think it's average. For example, air-conditioning network is the standard configuration. Apart from that, there is a kind of compartment in the undergraate laboratory. There is no compartment here, just a few tables. Desktop? It doesn't exist. Before, someone on the Internet said to send a notebook? It doesn't exist. monitor? Only one or two, our classmates really can't stand blind, to the teacher to display fruitless, can only buy their own, resentment. The big data lab is better, basically similar to the common office, display, desktop and so on
3. Professional. This year's major has been merged and cancelled. Many people report big data, and there is no sister in other majors... My major is mobile soft, which was called mobile travel before. I think you have also learned about it on the college website. Maybe some people want to come to Zhejiang soft learning game development? It doesn't exist. Do traditional colleges and universities in China have the development of Zhenger Bajing ecation games? Maybe Beida Qingniao will. Before I heard a person say that he refused an offer to Zhejiang soft just to learn games. It's funny. If you have this idea, you'd better wake up. After all, the name has been changed now, which means that the college also realizes that this is a ridiculous thing. I don't know much about other majors. Big data is very popular now. Many people report that if they want to find a girl, they should fill in big data and complain. The design is in Hangzhou this year, not Ningbo. I don't understand Internet of things finance
4. Students. Baoyan's classmates would talk about their treatment before. I could only keep silent. There are 40000 tuition fees in the soft Institute, and there are no scholarships for those who guarantee research. However, there will be a subsidy of 700 yuan per month. After all, it is given by the state. Think of other places where there are still hundreds of students left after the tuition fee is paid for the scholarship. Besides the state subsidy, there will be money every month... As for the source of students, it's very common. The best should be the two Zhejiang University undergraate students, and one or two Tongji, one or two Chengdian. Others are 211 or double non. But it seems that there are also some big guys, such as one who used to talk in the group, it is said that he created anycodes site
4. Internship. Two years in soft college, but one year in school, one year internship, you should know. So if you're at the beginning of school, maybe you'll stay here for eight months. As for the school enterprise cooperation, there are a lot of enterprises listed on the official website that cooperate very well, and there are a lot of powerful signs at the entrance of the college. In fact, it's useless at all, and it doesn't have any sense of existence for students. Because at that time or go to social enterprise to submit resume interview, there is no college introction. However, there is a company in the college, which is a "fun chain" opened by teachers in Hangzhou and does blockchain. There are a lot of big data to learn from, and there are also some to move soft
5. Projects. There are not many projects. At least our laboratory is in the state of self-study now, because we are not interested in the interest chain of teachers, because there is something wrong with our majors. Why should we do big data for those who move soft. There are a lot of big data, and a lot of people go to the fun chain. As for other laboratories, it is not clear. I would like to say that instead of doing a project that is far from my own plan, or helping the teacher do some miscellaneous and irrelevant things (I love a classmate), it's better to study by myself quietly
6. Further study. Students who want to further their studies should not come here, because the soft college is a springboard for you to find a job. In less than a year, most of the water courses (as the predecessors said, I haven't started the course yet, but you can also learn a little about the courses and books on the website) are self-taught. Of course, last year there was a big bull who read a blog, a bunch of paper or something, but it was just an example, otherwise it would not have been publicized. There are two cooperation projects going abroad, one is a neon country, and the other is a maple leaf country. One of the predecessors took this road before. However, tuition fees need to be taken care of by themselves and are very expensive. Let's forget about the children from working families
7. Life. Dormitory conditions are good, maybe because I am in the north, I was hurt by the conditions there. Four people, single bathroom, single bath, electric water heater, water dispenser. Air conditioners need to be rented by themselves, with a deposit of 1200 + 400. In addition, this is a very suburban place, there is no direct subway station is very hurt. There is only one barber shop around the dormitory, and the drugstore and hospital are far away. Usually, if you want to watch a movie or have a dinner together, you have to take the bus to the city
canteen, I'm really speechless in this canteen. Let's talk about it. The canteen here is very small, only one and a half floors. Big pot rice several windows + 34 other windows, no, a long time is easy to get tired of. This is understandable. After all, there are few people here. But the canteen is not the logistics of the school, it is outsourced. According to the undergraate experience, the big pot window is cheap and affordable, but here my life experience has been completely subverted. For the first time, I saw a canteen that could combine the three points of low weight, high price and bad taste. Here, the rice is in a bowl, a very small bowl, and the dishes are in a dish, a very small dish. I order a bowl of rice with one meat and one vegetable, which often reaches 11
I hope I can help you
