JD blockchain white paper

1.

At noon, 31 year old Guo Yang (not his real name) had just finished his morning technical meeting, and then he had seven or eight hours of technical discussion waiting for him. He rarely had time to get out of his work and have a meal with his friends. When he heard the other party say "blockchain technical director's annual salary is 1.5 million", his hand trembled and the bowl almost turned over

Zhang Zuoyi's goal now is to complete the transformation of blockchain technology in other scenarios in the same way. He said that as the team has done more and more, we can see that there are more than 300 online brands, and there are nearly 8000 procts. Just like building blocks, he is building his cooperation relationship on the basis of the cooperation of some brands

Guo Yang is also full of ambition at the moment. At 9 p.m., he finished his shift and had dinner with friends in the company canteen. While talking about the latest progress of the blockchain project, he experienced the ups and downs of the blockchain instry and heard some sad or happy news. On the contrary, he felt that the blockchain technology had more vitality and was worth exploring. Thinking of this, I feel that my ambition has been released by my current work, and I am looking forward to establishing a career that really belongs to blockchain technology

Blockchain is the hot spot at present. Taking advantage of this heat, blockchain companies and block platforms are pouring out from all directions. Blockchain talents instantly become the biggest recruitment outlet, with an average salary of 25000 yuan. The demand for talents is still in short supply

on the recruitment website, Shanghai, Beijing and Hangzhou have a large demand for talents, and the conditions and annual salary given by the companies that recruit talents related to "blockchain" are about 500000 to 800000 yuan, and even millions of annual salary. However, the current recruitment demand is still biased towards technical talents, such as blockchain system engineer, blockchain technical director and blockchain architect

enterprises recruit blockchain talents one after another, but the demand for talents is still insufficient. According to the talent trend report of 2018 peak season, in the first two months of 2018, the recruitment demand for blockchain related talents has reached 9.7 times of the same period in 2017. Meanwhile, the number of companies publishing blockchain related positions has increased by 4.6 times and the talent supply has increased by 235% year on year, but the stock is far lower than the actual demand

A: the main application fields of blockchain technology are finance, Internet of things and logistics, public service, digital right, insurance and public welfare

First, in the field of finance,

blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields

Second, the Internet of things and logistics

blockchain can also be naturally combined in the field of Internet of things and logistics. Through blockchain, we can rece logistics costs, trace the proction and delivery process of goods, and improve the efficiency of supply chain management

Third, in the field of public service, blockchain is closely related to people's proction and life in the fields of public management, energy and transportation. However, the centralization of these fields also brings some problems, which can be transformed by blockchain

Fourthly, in the field of digital right, through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works and ensure the authenticity and uniqueness of ownership

In the field of insurance, insurance institutions are responsible for fund collection, investment and claim settlement, and often have higher management and operation costs

Sixth, the data stored on the public welfare field

blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios. The relevant information in the public welfare process, such as donation project, collection details, fund flow, recipient feedback, etc., can be stored on the blockchain, and can be made transparent and public, which is convenient for social supervision

5. What you see and understand is completely correct. Now all those who are playing blockchain are all such deceptive things. They are just playing a slogan instead of a real blockchain. Big regular companies are playing this slogan to cheat people. They are very speechless

6. 1060 graphics card with other configuration, can run computing, quite a lot of people use this model of mining
if you can't operate, it is recommended that you see if there is a problem with the software, if there is no problem with the software, it is the problem of the graphics card itself, it is recommended to change the graphics card, or carry out reverse factory maintenance

7. First, you need to know what chips are
a chip is definitely not a technical indicator, but refers to who controls most of the circulating capital stock of a stock, and who plans to compete with these stocks next, that is, chips
then, to put it simply, the chips are in the hands of the company faction or the market faction, so the stock price is easy to rise but hard to fall. But if it is in the hands of retail investors, it is easy to fall but difficult to rise
finally, it is necessary to subdivide the characteristics of chips held by different main players. For example, the holding of foreign funds by national team legal institutions will be a medium and long-term trend, while hot money will be mainly short-term speculation

I don't think you should feel much. Let me give you a practical example
February 10 this year. Tongli cement trading that day, you see the main shipping finished
from any technical analysis knowledge you can find on the Internet, I can tell you for sure that I can't see it
it can only be judged from the chip side
at the end of 2014 and the beginning of 2015, Tongli cement had a continuous and intensive block trading record for a period of time. You can make your own inquiry. What you buy is the business department on Huayuan road in Zhengzhou, and then Tongli cement company is in Zhengzhou. From this, you can guess that what you buy in this block transaction is internal members of the company
of course, it's just a conjecture, but in the first quarter of 2015, only the second largest shareholder of Tongli cement increased the purchase amount of this block transaction. So here's 100% evidence
on February 10, this year, in the dragon and tiger list of Tongli cement, you can see for yourself who is the number one seller
Garden Road, Zhengzhou
if the main force sells its seats in the dragon and tiger list, it means that the shipment has been finished. Otherwise, when others know how to continue to sell
so that night, you can understand the hot money that caused the trading limit to rise when you buy on the same day. On the second trading day, you have to kill more and run away regardless of the cost. For this, you can compare the list of the top five in the dragon and tiger list on February 10 with the list of the top five in the next trading day
then Tongli cement has been falling now
each of these conditions is real data, not illusory figures or indicators. You can feel it for yourself

8. The Clarification Announcement of EasySoft is that the company is engaged in factoring business, not blockchain business.

9. Such a large number of stocks, after more listed companies, this is the normal. It's not what it used to be: it's gone. It's not so easy to stay away from junk stocks and turn junk into Phoenix.
