1. Centralized storage and distributed storage
most of the current storage is centralized storage, which is stored in the traditional centralized server. If the server goes down or fails, or the server stops operating, a lot of data will be lost
blockchain, as a distributed database, can solve this problem well. This is determined by the technical characteristics of blockchain. The digital records on the blockchain can not be tampered with or forged. The smart contract enables us to work together more efficiently, so as to establish a credible digital economic order, improve the efficiency of data flow, break the isolated island of data, and create a new storage mode.

2. Ueex blockchain technology application summit, through keynote speeches, round table forums, innovative projects and other forms,
3. IBM, Microsoft, Oracle, Accenture, Tencent, Alibaba, Jingdong, network, etc. have all done it. Many large banks, including Ping An Bank, have also launched their own blockchain solution platforms or solutions. However, it should be added that large companies do not mean strong technical strength, because blockchain is still in the hot stage of concept in the world. Unicorn blockchain companies are likely to emerge in the future, such as EOS abroad and Binhe Yun patent technology and application landing in China are much higher than those of large companies.
4. There are two ways to connect the core switch to the general switch in the computer room:
the first way is through the "optical fiber + optical mole", that is, the general switch is connected to the optical port of the core switch through the uplink optical port, combined with the optical mole and optical fiber
the second way is through the network cable, which generally requires the core switch to have an optical multiplexer port. At this time, the general switch can directly connect with the RJ45 port on the core switch through the network cable.

the margin ratio and handling charge are stipulated by the exchange, but different companies add different amount on the exchange
our company adds the least amount: if the margin is not added, the handling charge is only 0.01 0.01
6. How blockchain can bring about a "revolution" in personal data protection
US media disclosed on the evening of 17 local time that Cambridge analysis, a British company deeply involved in the scandal of abusing personal privacy data, originally planned to launch a personal privacy data storage service and sell it in the form of encrypted currency through blockchain technology. The concept of personal information encryption and monetization is not new. The key to this idea is everyone's autonomy of personal information. Some people in the instry believe that blockchain technology may bring a "revolution" in personal data protection
in the era of big data, personal data is considered as precious as gold. Personal data leakage is worrying, but the vast majority of people can't be cut off from the Internet because of the fear of data collection. At present, enterprises, schools, hotels, social networking sites, etc., which are responsible for keeping personal information, often fail to take the responsibility. Experts believe that blockchain technology, as a "middleware" with encryption, trust, point-to-point, and difficult to tamper, is expected to solve this problem
the emergence of blockchain technology makes it possible for everyone to control their own personal data by transferring the control of personal data from Internet companies to users themselves. Through it, users' personal data can be associated with their personal digital ID card. Users can choose whether their digital ID card is anonymous, pseudonym or public. They can also access the blockchain application platform from any device anytime and anywhere to control their Internet personal data
for example, the information on the block chain of someone's ID number may be converted to a series of ciphertext, and the face image information is also encrypted. When he checked in at the hotel, he only sent the cipher ID number to the hotel through application. The hotel compares the information with the encrypted data on the block chain application, and does not need to know any real information of him, but as long as the encrypted data match the result, it can guarantee the check in.
at the same time, the development of big data and artificial intelligence needs a lot of user data resources. Users can selectively sell their personal data as cryptocurrency and receive certain returns. For example, if e-commerce needs user data to develop a new application, users can choose to sell their own shopping history data, but their address, account number and other information can still be kept confidential
in the field of gene sequencing, blockchain applications have begun to challenge the "way to make money" of traditional gene sequencing companies selling personal data
in recent years, gene sequencing services for ordinary people have been popular. Take "23 and me" chromosome biotechnology company in the United States as an example. Consumers only need less than $100 and a few mouthfuls of saliva to get family genetic information. If they pay another $80, they can get in-depth analysis of genetic health risks and other aspects based on the original data. However, the company was not satisfied with the revenue from sequencing services. It also sold millions of customer genetic data to pharmaceutical companies by classification and packaging. The Parkinson's disease data sold in early 2015 alone amounted to $60 million. Many similar biotech companies, while obtaining service income from consumers, resell the data of consumers to "earn double money"
in February this year, George church, a geneticist at Harvard University in the United States, founded "nebula gene", hoping to break this pattern through blockchain technology. The company plans to complete the whole genome sequencing at a price of less than US $1000. The cost is borne by the customers. In return, the customers can intuitively understand their own genetic information and corresponding disease risks, and also have the autonomy of sequencing data. The security of genetic information will be guaranteed by blockchain technology. At the same time, it will be encrypted and monetized, and it will be stored and sold according to customers' wishes
the company plans to launch a kind of "Xingyun coin" as the trading medium. Customers can exchange their genetic information into "Xingyun coin", and they can also use "Xingyun coin" to pay for their own sequencing expenses. Pharmaceutical companies can purchase "Xingyun coin" with traditional currency to obtain the genetic information data of ordinary people. The whole trading process is completed through the blockchain platform, Encryption is transparent and secure
chech said that after integrating the cost of sequencing, genetic information protection, data management, genome big data processing and other factors, blockchain technology allows more people to truly "own" their own genetic information.

7. School of Geology and exploration engineering of Xinjiang University
the predecessor of School of Geology and exploration engineering of Xinjiang University is a teaching and research group of metal Department of Sino Soviet School of mining technology established in 1953. The teaching and research group was changed to geology department when Urumqi mining school was established in 1955, and to mining department when Xinjiang mining and Metallurgy College was established in 1958. In September 1979, two undergraate majors, mining and mining machinery, were abolished. After the geology major was left, the Department of mining was renamed the Department of geology. In 1998, it was renamed the Department of resources and environmental engineering of Xinjiang Institute of Technology (hereinafter referred to as the former Department of geology of Xinjiang Institute of Technology). The development of the College of Geology and exploration engineering of Xinjiang university can be divided into three stages: ① the former Department of geology of Xinjiang Institute of Technology (1953-2000); ② School of resources and Environmental Sciences of Xinjiang University after the merger of former Xinjiang Institute of technology and former Xinjiang University (from 2000 to January 2008); ③ College of Geology and exploration engineering, Xinjiang University (January 2008 to present). The first section is the evolution of the College of Geology and exploration engineering. The Department of resource and environmental engineering of the former Institute of technology is the same age as the former Xinjiang Institute of technology, and has gone through several merging processes. The Department of resources and environmental engineering was first established as a teaching and research group of the metals department of the mining technology school jointly run by China and the Soviet Union in 1953. It was the Geology Department of Urumqi mining school in 1955. In 1958, the "technical school" was renamed as "Xinjiang Institute of mining and metallurgy". Based on the specialty of "metal mineral and petroleum geological exploration", the Department of mining was established. The key teachers are: Li yaozeng, Zhu Xingnan, Wang Gongke Xu Zhongping, Zhang Xidong, etc. Two majors of "metal mineral and petroleum geological exploration" were set up, and "707 geological team" was set up at the same time, which led to the teaching road of combining theory with practice. Mine geology, regional geological survey and mineral general survey were carried out. In 1958, it began to recruit undergraates. In 1966, the "Xinjiang Institute of mining and metallurgy" was renamed as "Xinjiang Institute of technology". The original Department of geology was changed into the Department of mining, under which there are two majors: Mineral Survey and exploration and underground mining of metal minerals. In 1981, the major of underground mining of metallic minerals was abolished, and the Department of mining was changed to the Department of geology again, and the major of mineral survey and exploration was still set up. With the reform and opening up and the demand for talents in Xinjiang, in 1998, with the approval of the Ecation Committee of Xinjiang Autonomous Region, the original Department of geology was changed to the Department of resources and environmental engineering, with three specialties: resources exploration engineering and Technology (mineral survey and Exploration), resources exploration technology and Engineering (hydrological and Geological Engineering) and environmental geological engineering and technology. In 1978, the subject "mineral survey and exploration" was the first master program approved by the state in Xinjiang. Today's College of Geology and exploration engineering has gone through three stages of development: the Department of geology of the former Xinjiang Institute of Technology (1953-2000), the College of resources and Environmental Sciences of Xinjiang University (2000-2008) after the merger of the former Xinjiang Institute of technology and the former Xinjiang University, and the College of geology and exploration engineering of Xinjiang University (2008-now), It has become an important base for professional ecation, high-level personnel training and scientific research in the field of resource exploration and Engineering Science in Xinjiang. In teaching, it has formed a relatively complete training system for undergraates and postgraates. In teaching and scientific research, they undertake different teaching and research tasks, and have basic teaching laboratories with complete equipment. We have trained and formed a reasonable number of academic leaders and young teachers with high ecation level, which has laid a solid foundation for the cultivation of talents in the field of geological resources and geological engineering. He has made outstanding achievements in personnel training. Led by the late Professor Li yaozeng, he has trained more than 1000 undergraate professionals and more than 200 master professionals, including academician Jia Chengzao, academician of Chinese Academy of Sciences and vice president of PetroChina. He has made certain contributions to the economic construction of the autonomous region and the country. At present, the College of Geology and exploration engineering has a strong comprehensive strength in the field of geological resources and geological engineering, and will create a brilliant future in the new century. The second section is the general situation of the college. The College of Geology and exploration engineering of Xinjiang University is the earliest teaching and scientific research institution in Colleges and universities in China. At present, the teaching specialties of the college include: resource exploration engineering, exploration technology and engineering, and mining engineering; There are three master's degree awarding points: "mineral survey and exploration", "Earth exploration and information technology", "mineralogy, petrology and deposit science". It has a relatively complete undergraate and postgraate training system from bachelor's degree to master's degree. At present, there are 33 teaching staff in the hospital, including 5 professors, 14 associate professors, 9 lecturers, 9 doctoral degree teachers (the other 4 are studying), and 7 master's degree teachers. There are 417 undergraate students, 58 master students and 5 postdoctoral project researchers in the "geological and mineral research direction" of Xinjiang University. The College of Geology and exploration engineering has formed a new system of teaching and scientific research. At present, there are basic geology teaching and research section, resource exploration teaching and research section, exploration technology and engineering teaching and research section and mining engineering teaching and research section. The college has nearly ten million yuan worth of scientific research and teaching equipment, good infrastructure, complete laboratory construction, which provides good conditions for teaching and scientific research. Since the College of Geology and exploration engineering was separated from the College of resources and Environmental Sciences in January 2008 and established a new college, the college reference room is still under construction. At present, there are more than 5000 books and periodicals in Chinese and foreign languages. In 2003, the subject of "mineral survey and exploration" was listed as the key subject of the autonomous region; At the same time was included in our school & quot; 211 Project & quot; Focus on the construction of disciplines. Since then, the autonomous region and the school have invested in discipline construction funds every year, and the discipline has entered a period of leapfrog development. There are three main research directions: (1) Central Asian orogeny and mineralization 2) Identification and prediction of large ore concentration area 3) Application of "3S" and multi-source information synthesis technology in geological prospecting. In recent five years, Professor Zhang Xiaofan, Professor Sun Baosheng and others have undertaken the national key basic research project "973" sub project, and 9 scientific research projects above the provincial and ministerial level, such as the projects supported by the Ministry of science and technology. In the past five years, it has undertaken 53 vertical and horizontal projects at all levels, with a total fund of 15.8379 million yuan; Published 27 high-quality papers in core journals at home and abroad, 4 of which were included in SCI, 1 in EI and 2 in ISTP. In the past five years, a series of research achievements have been made in the fields of identification and prediction of large-scale ore concentration areas, application of "3S" and multi-source information comprehensive technology in geological prospecting, among which, three second and one third prizes have been awarded for excellent academic papers in natural sciences of the Autonomous Region, and one third prize for excellent academic papers in natural sciences of Urumqi, Xinjiang University Natural Science Achievement special prize once. Won the third prize of excellent teaching achievement in the autonomous region once; In the evaluation of excellent teaching achievements of Xinjiang University, he won two special prizes and one second prize. One monograph and one college characteristic textbook were published. The college always takes "ecation should face modernization, the future and the world" as the guiding ideology, earnestly implements the party's ecational policy, takes "seeking truth, striving, unity and innovation" as the ecational philosophy, and takes cultivating qualified talents with good moral quality and comprehensive quality as its own responsibility. Over the past few years, the college has always focused on the identification and prediction of large ore concentration areas in Xinjiang and Central Asia, contributing to the economic construction of Xinjiang and the scientific implementation of the western development strategy.

8. Friends, the 2021 Internet Yuelu summit · Wanbao blockchain forum was held in Loudi City, the "chain city". The theme of this forum is "blockchain and national / national data strategy".
9. For your problem, its coverage is too large and profound! At present, the existence of QQ coin and all network virtual exchange items is to make the company
profitable, and its cost can not be superficial. Who knows or stipulates how much a hat and a dress in QQ embroidery are worth? How much do I sell
it is not the same as a real commodity
you need to estimate its value and how much benefit it can bring to employees. No matter how to determine its cost, it is also virtual. In principle, as long as I meet my
profit goal, this is its cost! It's hard for such a huge system to analyze experts, not to mention you and me? I have a brief understanding as follows
first of all, in Tencent, q-coin virtual transaction phenomenon, a variety of payment means of goods have been derived from a single commodity consumption payment in disguise.
when it is used as the equivalent exchange virtual circulation in the way of RMB, he already has the concept of currency, as a value measure, which is
the intrinsic value measure of goods, In Tencent's website, q-coin can be used to buy virtual goods, such as a virtual QQ show clothes is better than a few q-coins, a virtual avatar is also better than a few q-coins, senior members can use q-coin to pay es, a senior QQ group needs 30 q-coins every month. Q-coin and other virtual currencies can not only purchase various network services provided by their own home, but also purchase network services provided by other enterprises on the Internet, such as Jiangmin antivirus software and other popular software on the network
with such a premise that interests cover a wide range and profits are rampant, all kinds of activities of q-coin trading become more and more interesting
on taobao.com, the seller's quotation for RMB to q is 0.5 yuan to 1q yuan, and the buyer's quotation is generally 0.45 to 0.47 yuan to 1q yuan in private. In addition, the method of purchasing q-coin has been simple
from dealers. It has developed to be able to apply for q-coin with face value of 1
, 2, 5, 10 yuan each time by dialing voice phone or mobile phone, which is equivalent to 1, 2, 5, 10 yuan dected from the telephone fee# Then how to get the source of goods at a low price, there are some new problems, such as the current market price of the serial number is 10000 numbers. If it is first-hand, the price is about 220 yuan. Then we can check the number through the serial number tools: jqq, PQQ, etc. the machine is fast and the network is good. We can check more than 10000 numbers in an hour, Can automatically find out each number
how many Q coins, game currency, level, whether there is password protection, points and so on can be at a glance
generally only sell 1-9. Some people sell 1-4, 5-9 separately. The price is about 1-4.14 yuan and 5-9.23 yuan respectively. It can be said that Q coin has the most negative nature of
but it is not difficult to find that in the case of incomplete relevant laws in China, the hidden dangers can not be ignored
the above is limited to space, and I only talk about some rough and obvious things. I hope you can study them together!
