2. Is it easy to find a job in the blockchain direction?

Professional talents in the blockchain direction are currently very easy to find jobs. This aspect is an area that the country currently attaches great importance to in price comparison, and it has increased There are many national-level projects and blockchain companies currently have a huge demand for talents. For example, Qulian Technology, a relatively well-developed blockchain technology company in China, has been recruiting in schools across the country a while ago. Dear, you can; Blockchain What is the future of blockchain technology? The following content is just my personal experience and opinion, for reference and learning only. I have been exposed to the blockchain industry for many years, and have my own opinions and understanding from its ups and downs. I personally think that blockchain technology The reason why it is still very good is that blockchain technology is the next generation after the Internet.
Knowledge expansion:
As an underlying protocol or technical solution, blockchain can effectively solve the trust problem, realize the free transfer of value, and provide digital government certificate storage and anti-counterfeiting data services in the transaction settlement of digital currency financial assets. Digital currency has broad prospects in other fields. After experiencing physical precious metal banknotes and other forms, digital currency has already been developed. Blockchain technology also has a vitality, which is that it is a relatively perfect thing under the premise of current computer technology, but These architectural computing models will be vulnerable to the impact of quantum computer models, so even if there are broad application prospects, if quantum computer technology develops rapidly, blockchain technology may be there.
In addition, blockchain technology is deriving into new business formats and becoming a new driving force for economic development. Blockchain technology is promoting a new round of business model changes and becoming an important support for building an honest social system. 3 Future application prospects are broad In the past, the circulation of physical banknotes was difficult to trace, but with the application of blockchain technology.
Blockchain engineering employment prospects and directions:
1. In addition, as an emerging technology, there are still many technical difficulties when applying blockchain in the actual production environment of the financial industry, such as throughput. Technological innovations such as blockchain, such as scalable consensus mechanism, privacy and security manageability, are of great significance to the financial industry and are expected to accelerate the process of "trusted digitization" and continue.
2. Research strength has increased and research results have been significant. As of the end of 2019, the number of blockchain research institutions in my country has reached 97. In addition, domestic universities have deployed blockchain technology research, strengthened innovation in theoretical knowledge of blockchain technology, and improved university campuses. Blockchain technology research and development capabilities. As of the end of 2019, my country’s universities have participated in strengthening blockchain technology research and development.
3. In 2020, blockchain will be included in the category of “new infrastructure” by the country, with at least 7 provincesIn the same year that the blockchain support policy was introduced, blockchain technology is gradually moving from concept to implementation, with more application scenarios blooming. "Blockchain+" various industry applications have become a symbol of the continuous maturity of blockchain. In 2020, "Blockchain+" Chain+".
4. Excellent talents can inject fresh blood into the development of the industry. More and more cities are stepping up the introduction of blockchain talents. The demand for technical talents ranks first. From the perspective of job distribution, my country’s blockchain in 2019 Technical talent demand accounts for the largest proportion of the industry's talent demand, reaching about 445%, far exceeding other types of work. At the same time.

3. Blockchain employment direction and prospects

5. Why is it said that recruiting people for blockchain positions is all based on deception

However, where are the opportunities for these innocent employees? To put it bluntly, some blockchain entrepreneurs only want to be "empty-handed" and exploit them layer by layer through "fooling". The use of asymmetric industry information has caused projects such as blockchain and digital currency to be over-packaged, giving people a feeling of "hope". The inherent "bad roots" of these blockchain entrepreneurs have, to a certain extent, led to the "sick" development trend of the industry.

Some blockchain entrepreneurs clamor to embrace the times, embrace changes, and embrace the future, emphasizing the charm of decentralized “fairness”. But in reality, it is done for personal gain and harms the interests of job seekers and other related groups. This in itself is a great injustice.

The asymmetry of information does not last forever. Blockchain, digital currency, etc. are all areas worthy of attention, but they cannot always be regarded as unlimited squandering capital by some entrepreneurs. And for wantingJob seekers who join it must keep their eyes open, otherwise they may be "surprised" if they are not careful.
