1.
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
2. Liu Dahong, founder of Lord technology, first proposed the concept of "contract engineer" of blockchain in his speech at Peking University. Intelligent contract engineer will become the rule designer of contract society
in the future, contract engineers will design rules with unlimited granularity, publish them to the blockchain, and then intelligently execute them by countless other small contracts according to the rules, so as to solve the global problems of complex networks in a complex society. Contract designers and developers with "contract engineers" as super nodes will become Internet evangelists in the era of blockchain. Issue a talent call order: recruit blockchain contract engineers with an annual salary of 30 bitcoins.

3. At present, blockchain is still in its early stage, and then the early (since 2013) research on blockchain contracts are basically multimillionaires, so now basically there is a price without market, and the price rises naturally. By the way, blockchain is the technology behind bitcoin, and contracts are the first and most successful projects of TaiFang, and their prices have increased by at least several thousand times
4. To help prevent novel coronavirus pneumonia, we should do a solid job in "six stability", fully implement the "six guarantees" task, and promote employment and expand jobs. Recently, the joint supervision and Administration Bureau of the Ministry of human resources and social security and the National Bureau of statistics have released a number of new occupation to the society recently. Including: "blockchain engineering and technical personnel", "urban management grid member", "Internet Marketer", "information security tester", "blockchain application operator", "online learning service engineer", "community health assistant", "ability evaluator for the elderly" and "additive manufacturing equipment operator". This is the third batch of new occupations issued since the promulgation of the people's Republic of China occupational classification dictionary (2015 Edition). In addition, five types of work, such as "live broadcast salesman" and "Internet information auditor", were released, and three types of work, such as "epidemic prevention", "disinfector" and "public health administrator" under the occupation of "public health assistant attendant", were upgraded to occupation
the Ministry of human resources and social security collected the new jobs from the public, organized the experts to evaluate and demonstrate the new jobs in strict accordance with the principles, standards and proceres of job classification, and publicized them to the public through Internet media. The new occupation occupation mainly involves novel coronavirus pneumonia areas, and the new format of adapting to the needs of employment and Entrepreneurship of graates. It also has the following characteristics to help the poor and the rural transfer workers. Second, the development of Internet technology has given birth to a variety of entrepreneurship and employment models; Third, the development of information technology puts forward new requirements for network credit and security
What do the two new blockchain professions do

5. Blockchain mainly solves the trust and security problems of transactions, so it proposes four technological innovations to solve this problem:
(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

6. After the fire of new infrastructure, the blockchain instry will certainly have a good development. In the new infrastructure, data is becoming more and more important. Because the combination of blockchain and these technologies can ensure the credibility of data and ownership
an obvious phenomenon is that many provinces and cities are vigorously promoting the implementation of blockchain government service applications. For example, in Hunan, there are SMIC (Changsha) blockchain public platform, Loudi blockchain real estate registration platform and so on, which are blockchain government applications that have been implemented and well done.

7. At present, blockchain technology is mainly used in finance, medical treatment, authentication, smart contract, sharing economy, digital assets and other fields. In the future, it may break through the application of all walks of life, such as Internet, energy, proof of existence, social media, government departments, kindness, health, music right, etc Applications in many fields such as consumers:
there are relatively few blockchain technology R & D companies, and Heshu software is an innovative company for blockchain technology R & D
according to the relevant data report of the UK, at present, more than half of the world's large companies (with more than 20000 employees) are considering and actively deploying blockchain technology. In addition, among all the enterprises surveyed, two thirds of them said that they would incorporate this technology into their systems by the end of 2018. This also confirms the unlimited potential of blockchain in the future development of enterprises.

8. Blockchain can be involved in all walks of life, such as food, medical, health, manufacturing, franchise, ecation and many other fields. Due to the characteristics of unchangeable data, decentralization and multidimensional judgment and analysis of information recorded by blockchain. Blockchain is more convincing to investors and users than big data mobile phone, and it is highly recognized by the world at all levels. This black technology is bound to set off a wave of technological revolution in the world.
9. I think it should be that the courses based on software engineering have added some content related to blockchain technology, which can be regarded as the implementation of some specific content
