Blockchain of Computer Institute
Although the blockchain technology is still in the early stage of development, the corresponding talents are in short supply
Computer (software engineering, information and computing science, information technology, information security, etc.)2, mathematics related majors
3, economics related majors
4, cryptography
at present, various well-known institutions around the world are competing to launch blockchain teaching courses, Some universities have even set up corresponding completion certificates for blockchain courses
an overview of blockchain Technology: architecture, consensus, and future trends
artificial intelligence technology involves a lot of algorithms and has high requirements for mathematics! Also need learners to have a certain understanding of computer
for the above two, you need to know something about the computer major, but nothing is difficult in the world. If you want to learn, you can do it.
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 P>
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 talentsblockchain (English: blockchain or block chain) is a kind of distributed database . You may have heard about bitcoin, which is the core technology. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a network transaction, which is used to verify the validity of the information and generate the next block. In a popular concept, blockchain is an account that everyone can keep. In a company or organization, most people only have the right to keep accounts, while only a few people with professional training have the right to keep accounts. Of course, blockchain is not an account book in the traditional sense. It has the following three key points in technical principle: first, decentralization. In a network practicing blockchain technology, each computer covered by it can read and add records. From the perspective of account book, they are the people who keep accounts together, and there is no authoritative person to guide and correct them. Second, asymmetric encryption. Although everyone can remember this account, they will not be able to read it unless they are in the Bureau. Because, in the accounting process, everyone follows the unified encryption rules, but when reading, they must use their own unique decryption method. Therefore, although everyone keeps this constantly updated account, the part they can read is only the one they can decrypt, that is, the part related to themselves. Third, time stamp. That is, time stamp (English: timestamp), refers to the string or coded information used to identify the recorded time and date. Each block on the blockchain is arranged in sequence according to the time it is generated, and is confirmed by collective authentication. Moreover, previous records cannot be modified. Just like in an account, we can index and verify the previous content through the records after a point in time. Once these contents are confirmed, it will be more difficult to tamper with them
blockchain technology is to maintain a growing distributed database of data records. These data are associated with all the data written before through cryptography technology, which makes it difficult for the third party or even the owner of the node to tamper with. Block contains the data that need to be saved in the database, and these data are written into the database through block organization. Chain usually refers to the use of Merkle tree and other methods to check whether all the current blocks have been modified. This is familiar to code farmers who have used git for a long time. Recall how to modify git's history
blockchain technology is mainly divided into three categories, which are open, collaborative and private
public blockchain
example: bitcoin, Ethereum frontier. The data on the public blockchain can be accessed by all people, and all people can issue transactions waiting to be written into the blockchain. Participants in the consensus process (corresponding to the miners in bitcoin) maintain the security of the database through cryptography technology and built-in economic incentives. Open blockchain is completely distributed
highlights and pain points: the open blockchain is completely distributed and has all the characteristics of bitcoin. However, it needs sufficient cost to maintain the system operation and relies on built-in incentives. At present, only bitcoin in the public blockchain is safe enough. If the algorithm is the same as bitcoin, it will be safe; There are no built-in rewards, but they are not; It's easy to concentrate on the attack of computing power (for example, as long as the raid sweeps goods and a large number of graphics cards), and take jujube pills. The more valuable the data on the open blockchain is, the more important it is to examine its security, transaction cost and system scalability
federated blockchain
example: audit system tried by hyperledger and Deloitte. The nodes participating in the blockchain are selected in advance, and there is likely to be a good network connection between the nodes. Other consensus algorithms without workload proof can be used on such a blockchain. For example, a blockchain has been established among 100 financial institutions, and more than 67 institutions must agree to reach a consensus. The data on such a blockchain can be public or internal to these node participants. Distributed in a partial sense
highlights and pain points: collaborative blockchain can achieve a good connection between nodes, only need a little cost to maintain operation, provide rapid transaction processing and low transaction costs, has good scalability (but the scalability will decline with the increase of nodes), and data can have certain privacy. Developers have the ability to change the protocol under the consensus. There is no problem with bitcoin hard fork, but it also means that everyone can tamper with the data together under the consensus. Collaborative blockchain also means that the application scope of this blockchain will not be too wide, lacking the network propagation effect of bitcoin
private blockchain
example: Eris instries. The participating nodes are only users themselves, and the access and use of data have strict authority management. Most of the blockchain technologies recently announced by some financial institutions for internal use are vague, but they are probably all within this scope
highlights and pain points: private blockchain is actually a confusing term. Such a system is nothing more than a shared database in the traditional sense. Merkle tree and other methods are used to try to show that the data in it is verifiable. There are already mature solutions for such databases, and Merkle tree is only one of many mature solutions. It's easy for these projects to be "like eggs". Because the user has the final say, the data inside can not be changed, and there is not much protection for the third party. Therefore, many private blockchains exist by attaching to bitcoin, such as recording system snapshots to bitcoin regularly
