Leaving blockchain startups

Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information about bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

if such technology wants to be put into application, the biggest problem is the "Impossible Triangle problem"

that is, scalability, decentralization and security cannot be achieved at the same time, and only two of them can be achieved

most of the existing public chain projects in the market are difficult to put into use on a large scale

Because the blockchain technology is not mature at this stage, and the infrastructure is not perfect, many applications are limited, and the overall application is still in a very early stage

Pure blockchain technology can also be applied in non-financial fields. Here are some examples of blockchain technology application:

1. cross center sharing of provident fund blacklist
   ant financial blockchain and Huaxin Yong build "cloud platform of joint dishonesty punishment and deposit proof", Hainan province takes the lead in sharing the black list and deposit certificate of provident fund across centers and regions through the platform

2. business service blockchain platform
   the platform uses blockchain technology to open the service mode of "all-weather, zero meeting, one click" and applicants can apply for business license through the "blockchain + AI" platform, which takes only one and a half hours

3. Jingdong Logistics creates a blockchain traceability platform with one click traceability of beef and mutton

there are many areas where blockchain technology can be applied, and it does not have to be related to digital currency. Cryptography focuses on blockchain information< br />

In August 2014, the University of science and technology of China's new Alumni Foundation and the youth class Alumni Association jointly completed and released a survey of alumni professors in the youth class of University of science and technology of China. The survey shows that since the founding of the youth class of University of science and technology of China, more than 212 professors have been cultivated. Compared with before 2005, the proportion of "youth class professors" at home and abroad is higher, It has changed from "great contrast" to "extremely close"

"now the situation is different, and the number of people who stay in China for development and return home after study is increasing." Pang Huadong, who resigned from all his ties on Wall Street and returned home to start a business, said that the year he returned home to start a business has brought back his long lost enthusiasm

Pang Huadong

students of grade 95 junior class of University of science and technology of China. The picture provided by the interviewee

because the students in the junior class are younger, their self-care ability is weak, and they are under great learning pressure, many students, like Pang Huadong, do not pay attention to the details of life. In the first semester, Pang Huadong didn't have a haircut, and his clothes couldn't be cleaned. When he came home ring the winter vacation, his parents were shocked by his appearance“ Long hair, ragged and dirty clothes, like a beggar. " Pang Huadong couldn't help laughing when he told Red Star news about this

through one year's adaptation, the students in the junior class found their own research directions. The University of science and technology is very free to choose a major, and students can change it at any time if they don't get used to it. Pang Huadong has been to biology department and computer department, but finally returned to his favorite mathematics department. A large part of the reason for learning mathematics is that he has to find self-confidence in the strong young class. Pang Huadong won the first place in the 5th mathematics competition of China University of science and technology. He regained his confidence“ At that time, I thought that I could finally get the first place in one subject. " Pang Huadong said

it's a trend to start a business in China

in 1999, Pang applied for the master's degree in the University of science and technology of China before he graated from the University of science and technology. Then he went on to study for a doctorate and went abroad for further study, and made enviable achievements in research and work

in 2017, Pang Huadong was elected as the new chairman of the Council of the Alumni Foundation of University of science and technology of China, so he had to find time to take care of Alumni Affairs. In Pang Huadong's view, this work can reach tens of thousands of alumni of China University of science and technology, guide younger students and younger students, and at the same time, open up new horizons and new ideas“ Alumni are involved in all walks of life. I don't have any strange fields now. Even if I have, I'll get it by calling my alumni. "

Pang Huadong said that according to his observation, most of the more than 1700 students who graated from the junior class set foot in more cutting-edge majors. Even if they did not engage in research, those who returned home to start their own businesses were also in the fields of Internet, artificial intelligence, bitcoin, blockchain and so on

he said that in the past, ecation in China was relatively backward, so most of the students in the junior class chose to go abroad for further study. Now the situation has changed, and the number of students who stay in China for development and return home is increasing

in the year of returning home to start a business, Pang Huadong said that he had recovered his long lost enthusiasm and was excited every day. He said that he is now in a "gale". Like the arrival of the Internet era, he believes that a new era of blockchain will soon come, "I have to seize it."
