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 talentsdigital economy and blockchain Technology: he is one of the earliest scholars engaged in blockchain technology in China. He has proposed and developed such theoretical methods as smart contract engineering (SCE), legal code technology, verification as a service (VAAs), etc. in the fields of combination of digital economy and blockchain, planning and consulting of digital economic Park, digital governance of blockchain, and so on Blockchain scalability, Multi Chain interconnection and blockchain formal verification technology have in-depth research and patent achievements. He presided over the research and development of Beihang blockchain series procts, including various forms of blockchain systems with independent intellectual property rights, browsers, monitors, deployment tools and blockchain big data management system (opendata)
distributed parallel computing and network: he has been engaged in cluster computing system, high-performance computing, aerospace electronic bus, and integrated network information technology research in complex computing environment for a long time. He proposed and studied the theory of reconfigurable multi cluster computing based on wolf pack and applied it to practice, and developed several application software systems
formal design and verification methods: in close cooperation with irit and INRIA, we have established a Sino French joint research laboratory for formal methods, studied model driven formal design and verification methods, proposed a number of innovative extension technologies based on AADL and synchronous language signal, and developed a number of model transformation, model validation and verification methods Verification and automatic code generation tools
in recent years, he has published more than 60 papers on SCI / EI retrieval in important academic journals at home and abroad, edited new technologies of network computing (416 pages, published by Science Press in 2001), and cooperatively completed the national authoritative textbook introction to distributed computing system (490 pages, published by Tsinghua University Press in 2014), which won the first prize of 2016 textbook, It has been adopted by more than ten key universities. He has successively presided over and participated in a number of National Natural Science Fund, national key R & D projects, 863 major projects, Junkou 863 project, National Nuclear high-tech foundation project, aerospace fund, and a number of important engineering projects in aerospace field. He won more than 30 national invention patents and soft works, won the five-year achievement award of aviation fund in 2015, and won the second-class innovation achievement award of Instry University Research Institute in 2018.
(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
With all walks of life have begun to enter the blockchain instry, blockchain has undoubtedly become the world's largest wind in 2018. Since 2014, more than a dozen top universities in Europe and America, including MIT, Stanford University and Princeton University, have successively opened blockchain courses
now, it is no longer limited to the teaching of blockchain technology, and some people are ready to challenge the traditional ecation mode with blockchain technology. According to the times of higher ecation, a group of scholars from Oxford University announced that they would establish the world's first blockchain University, Woolf University
{rrrrrrr}
Course Platform demo according to the official website of Woolf University
actively promote the block chain credit certification
"hope the degree certificate will be widely recognized in the future"
however, there are no doubt many problems to be solved when applying an emerging technology to a new concept. Professor Michael sharens, a professor at the Open University of the UK, said that although the founding of Woolf university is a subversive force in the field of ecation, how to ensure high standards of teaching is a big problem. Although blockchain can ensure the teaching interaction between teachers and students, it can not guarantee the quality of teaching
in this regard, Dr. blocky told the media that the key to the quality of ecation is not whether there is a physical campus, but the ability of teachers. Of course, the school will also have relevant teaching quality supervision measures. First of all, only scholars with real doctoral degrees can join the platform as teachers, and they must upload certificates for verification
secondly, the top five colleges of the university will be composed of scholars with doctoral degrees from world-class universities. After the establishment of five high-quality colleges, Woolf will be open to other scholars one after another
in addition, a ranking system was established among colleges according to the number of teaching and the average score of students. Finally, the university will set up a review system for academic fraud and cheating, which will be regularly reviewed by the dean of the college
then, in addition to ensuring the quality of teaching, how can the academic records of blockchain obtain formal academic recognition
Dr. brocky said that blockchain can help the credit certification process, because the information records it provides are highly accurate and completely reliable. The European Commission has recently published a report on blockchain in ecation, but it will take some time to complete this process
before obtaining official permission, blockchain records will be temporarily used as a part of the application process. For the degree certification of early-stage students, the university will cooperate with existing universities and still use the traditional way to certify credits. In addition, at the initial stage of its establishment, the university will invite ecational institutions such as Oxford college to join the platform and make full use of their existing degree certification mechanism. At the same time, the University of Virginia Woolf has begun to actively seek ecation certification in the European Union and the United States, hoping that in the next 10 years, the degree certificate of Virginia Woolf University will be widely recognized
Dr. blocky said that Woolf university is the future ecation model, which combines online and offline ecation, and connects the world's outstanding students and teachers by building a global talent network“ I hope this model can improve the overall quality of ecation and provide a new way for students to acquire knowledge and achieve success, no matter where they are
Zhejiang 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
