market formation

the Internet has led to the emergence of a new market, which is a virtual market based on cyberspace. The Internet provides a lot of communication places for consumers, and also provides business market for enterprises. Enterprises must change from proct centered to service centered to customer centered. With the development of computer artificial intelligence technology and database technology, enterprises can conveniently collect customers' information, understand customers' needs in time, change business strategies and grasp economic arteries in real time

With the rapid development of computer and network communication technology, the application of Internet technology has graally penetrated into various fields of human activities, and the unlimited business opportunities that it contains make businesses turn their eyes to e-commerce. E-commerce is penetrating into all aspects of social and economic life at a speed that people can hardly imagine

the traditional finance is also closely watching this irresistible trend of global economic integration and networking. As a result, value-added services take art as the selling point and can be regarded as commodities; The sword in the game is not a brand-new financial services business philosophy - e-finance came into being

from the historical development process, to understand e-finance, we must start from the electronic finance and e-commerce. The so-called e-financialization means that financial enterprises adopt modern communication, computer, network and other information technology means in addition to Internet technology to improve the work efficiency of traditional financial service business, rece operating costs, realize the automation of financial business processing, informatization of financial enterprise management and scientific decision-making, and provide customers with faster and more convenient services, And then enhance the financial enterprise is the behavior of market competitive advantage

e-finance is a transcendence of financial electronization. Different from the electronic finance, the main technical basis of e-finance operation is the increasingly perfect Internet technology. Due to the characteristics of global connectivity, openness, quickness and low marginal cost of Internet technology, e-finance strengthens the restructuring and innovation of financial services business based on Internet technology, so that customers are free from the restrictions of business hours and places, and enjoy all kinds of high-quality and low-cost services provided by financial enterprises anytime and anywhere

with the development of Internet, the form of money is becoming more virtual, and there is an electronic money that only exists in the form of electronic signal

Virtual currency is the currency used for electronic circulation. Now the scope of virtual currency is very large, including q-coin, bitcoin and so on. With the development of digital currency, virtual currency is becoming more and more abundant, which may become the mainstream in the future. For example, BTC, EOS, bcbot and so on are not only virtual currencies, but also algorithms, landing projects and technologies

virtual currency is mainly issued by online game service providers to purchase game props, such as equipment, clothing, etc. But at present, the use of virtual currency has gone far beyond this category. Virtual currency can be used to buy game cards, physical objects and download services of some movies and software

real risk

as the proct of e-commerce, virtual currency has begun to play an increasingly important role, and it is more and more connected with the real world. However, with the growth of virtual currency, the relevant laws and regulations are lagging behind, which has laid many hidden dangers

fraud

the private transaction of online virtual currency has realized the two-way circulation between virtual currency and RMB to a certain extent. The activity of these traders is to buy all kinds of virtual currencies and procts at a low price, and then sell them at a high price to earn profits. With the increase of such transactions, there are even virtual mints. In addition to the virtual currency provided by the main company, there are also some people who specialize in "virtual coin making" to obtain virtual currency by playing games and then resell it to other players

Taking Wenzhou as an example, there are about seven or eight such "virtual mints" with four or five hundred practitioners. This not only creates a bubble for the price of the virtual currency itself, but also causes trouble for the normal sale of the issuing company. It also provides a platform for selling and collecting money and money laundering for various cyber crimes. p>

impact system

in modern financial system, the issuers of money are generally central banks, which are responsible for the management and supervision of money operation. As the equivalent exchange goods used to replace the real currency circulation on the Internet, the virtual currency on the Internet is essentially the same as the real currency. The difference is that the issuers are no longer central banks, but Internet companies

if the development of virtual currency makes it form a unified market, each company can exchange with each other, or virtual currency is integrated and unified, and all of them are based on the same standard and price, then in a sense, virtual currency is currency, which is likely to form a threat impact on the traditional financial system or economic operation

A vigorous "blockchain movement" is sweeping like a wave, threatening everyone around. From last year to this year, the debate over blockchain has never stopped. Is blockchain, as its advocate Chen Weixing said, the "spring of mankind", the "antidote to the global economic collapse", or as his doubter Zhu Xiaohu said, "blockchain is a fake outlet, and there is nothing left except currency speculation"

we think that this instry needs standards, otherwise we will talk about blockchain for a long time, and the concept of talking is not the same, and even some enterprises claim to make their own blockchain, and they just change the database. With the authoritative standard of trusted blockchain, we can screen out the enterprises that obviously sell dog meat, and let the enterprises that really do blockchain technology get endorsement

Ce: how does Tencent solve the problem of talent scarcity in the blockchain field

CAI Yige: our technical talents are basically transformed from Tencent. The blockchain instry is very new, and few people have done blockchain. Just like the arrival of mobile network in those years, it's very difficult for you to recruit Android and IOS developers. We all cultivate ourselves

Eth is the Federal Institute of technology of Zurich, located in Zurich, Switzerland. It is a world-renowned top research university. For many years, it has ranked first in European universities and enjoys the reputation of "the first university in Europe". It ranks sixth in the world in the comprehensive ranking of QS World Universities in 2020

The Federal Institute of technology in Zurich was founded by the Swiss Federation in 1854 and began to teach as a technical college in 1855. Initially, it consisted of six faculties of architecture, civil engineering, mechanical engineering, chemistry and forestry, as well as an organization integrating mathematics, natural sciences, literature, social sciences and politics

the Federal Institute of technology of Zurich ranked 9th in the world in the 2016 QS World University comprehensive ranking; In 2017, QS ranked the eighth in the world; Ranked 10th in the world in the comprehensive ranking of QS World Universities in 2018; Ranked 7th in the world in the comprehensive ranking of QS World Universities in 2019; In 2020, QS ranked the sixth in the world

the development status of eth

the Swiss Federal Institute of technology was established by the Swiss Federal Government in 1855 for the needs of national instrialization, which is a Federal University. It is not only for its own development, but also for the whole country, Europe and even the world to engage in scientific research. At the beginning, the university only had civil engineering, forest science, mechanical engineering and chemistry, and then added humanities, sociology and political science

the school has 26000 teachers and students from more than 100 countries in 16 departments, and its teaching and research fields include architecture, engineering, mathematics, natural science, social science and management science. For eth, the number of students enrolled and tuition fees are not considered at all. With the support of the federal government, the college receives as much as 9.2 billion Swiss francs a year for ecation, which does not include the use of property management and new teaching facilities

the college has also received up to 3 billion Swiss francs from third-party funding and its own technology transformation. All these funds are used for school running and scientific research, or most of them are directly used for more than 20000 students and 500 professors (full-time equivalent personnel of more than 9000 person years)

Even so, ETH continues to say that it is short of money in its annual reports in recent two years, and the reason is very simple. In order to compete with other institutions (universities), our independence is the most important, so we need a long-term sustainable financial support

last year, we expanded the enrollment of 4% of the students. At present, the number of students is 156% of that ten years ago, the number of professors has increased by 23%, and the number of scientific research personnel has increased by 53%. However, the government's scientific research funding has only increased by 42%, and the available area for ecation has only increased by 7%. We are facing great challenges

However, it is not surprising in Switzerland. Due to its unique ecation system, all resources in Switzerland are concentrated in 10 universities and 2 federal polytechnics. In other words, there are only 12 universities at the level of higher ecation, and the country is not short of money, so the current situation is formed

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

1. Q coin

Q coin, referred to as QB, also known as QQ coin, Tencent Q coin, etc. Usually its exchange rate is 1q currency = 1 RMB, with Tencent paipai net transactions are generally 10% off

QB is a virtual currency launched by Tencent, which can be used to pay for QQ bank number, QQ member service and other services. Tencent q-coin, through the purchase of QQ card, telephone recharge, bank card recharge, network recharge, mobile phone recharge card, one card recharge card and other ways to obtain

The face value of QQ card is 10 yuan, 15 yuan, 30 yuan, 60 yuan, 100 yuan and 200 yuan respectively

there is another kind of electronic cryptocurrency, qqcoin, which is not related to each other

2. Litecoin

litecoin, abbreviated as LTC, currency symbol: Ł; It is a kind of network currency based on "peer-to-peer" technology. It is also an open source software project under MIT / X11 license. It can help users make instant payments to anyone in the world

lightcoin is inspired by bitcoin (BTC) and has the same implementation principle in technology. The creation and transfer of lightcoin is based on an open source encryption protocol and is not managed by any central organization

3, infinite coin

infinite coin (hereinafter referred to as IFC) is a new digital currency, which has more circulation advantages than bitcoin, and fills the short board of bitcoin in the field of commercial circulation and promoting commercial operation. The positioning of unlimited money is to serve the daily life of small transaction payment

one transaction of infinite coin needs three confirmations, each confirmation takes three seconds, and the transaction confirmation speed is very fast. Because bitcoin transaction needs 6 confirmations, which takes about 1 hour, and lightcoin transaction takes 15 minutes, infinite coin is used in daily common transactions, which is more practical

infinite coin was released on June 5, 2013. Based on scrypt POW algorithm. A block is generated in 30 seconds. In the initial block, there are 524288 infinite coins in each block. After that, for every 86400 blocks generated, the number of coins in the block is halved, with a total of 90.6 billion. The difficulty of mining is adjusted every hour

Quark coin is not the currency in real life, it exists safely in the computer of global network

quark network is protected by six most advanced encryption algorithms to ensure that it can become a digital ledger. The whole network uses each of the six functions to generate a proof of work, and the coin maker must "verify" these transactions to ensure that each coin increase is real and effective

only regular computer can participate in ensuring that it can maintain a highly secure peer-to-peer network, which makes it more decentralized

quark coins can only be g up through the CPU of regular computers. In the first 36 weeks, a total of 247605120 quark coins will be g out. Since March 30, 2014, the annual quark coins set at 1050000 can enter the market through "digging", and the block reward will never be less than one, which is currently two

Zetacoin is an open-source digital currency based on SHA-256 algorithm. The initial coin mining is 160 million coins, and the subsequent annual inflation is a better incentive, To keep the hash of the network is not pure transaction cost

The total number of

zetacoin is 160 million, 1000 zets per block and half of 80640 zets per block

8. In the first half of Tencent's blockchain security report, technical experts believe that the current security problems caused by blockchain cryptocurrency mainly stem from three aspects: first, the mechanism of blockchain itself. There are loopholes in the design of blockchain smart contract represented by Ethereum, which brings serious economic losses
