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

It's not against the law

The laws and administrative regulations in China do not prohibit the proction, holding and legal circulation of bitcoin, nor do they prohibit the sale of bitcoin mining machines

2. The investment and transaction of "virtual currency" represented by bitcoin are on the rise. For this kind of virtual goods generated in the Internet environment after the development of Internet technology, there are policy and commercial risks in related transactions. However, under the premise of not violating the mandatory provisions of laws and administrative regulations, the contract signed by the parties is a valid contract

3. Bitcoin is generated by "miner" and "mining", and "miner" can be assumed by anyone in any place in the world. "Mining" is a process in which "miner" provides certain computer computing power according to the open source software provided by the designer, and obtains the special solution of the equation through complex mathematical operations, The miner who gets the special solution gets a certain amount of bitcoin reward

Because bitcoin is based on workload proof, it is related to computing power. To have computing power, we need to consume power, so its power consumption is very large. It is precisely because of such a large power consumption that the safe and stable operation of bitcoin system can be guaranteed

extended information:

according to the data of btc.com website, up to now, the computing power of the whole bitcoin network is about 51.65 eh / s, which is equivalent to 1.84 million bitcoin S15 (28T computing power, 1596w power) mining machines in operation, and the daily power consumption is about 69.92 million kwh. Divided by the current proction of 1800 bitcoins per day, excluding other costs, each bitcoin will consume 38800 kwh of electricity. "

from this point of view, although the current price of bitcoin is expensive, the cryptocurrency market website coinmarketcap.com shows that the current unit price is about $7900, but the cost of mining a bitcoin is not low at all

3. To understand the operation of nine trading platforms, "bitcoin trading network", domestic major platforms have either suspended the withdrawal of bitcoin and dogcoin, and the inspection team of the business management department of the people's Bank of China has also investigated other counterfeit currencies engaged in bitcoin trading, such as "China bitcoin", "cloud coin network", "good bitcoin", "btc100", Ethereum, etc., which are less affected, "Yuanbao network"
however. At present, the main persons in charge of nine bitcoin trading platforms in Beijing, such as "jucoin.com" and "dahonghuo.com", have an interview with "coin shell.com" to report the problems existing in the bitcoin trading platform, Ruibo currency, policy risks and technical risks, and to prompt the legal risks that may exist in the trading platform, The information on the official website of the people's Bank of China shows that on the afternoon of February 8, cash can be withdrawn and traded normally

4. In June last year, the Dao, the hottest project of Ethereum, was used by hackers to exploit the loophole of smart contract and transfer 50 million US dollars worth of Ethereum currency. In order to recover the investors' assets, the Ethereum community finally voted, and most of the participants agreed to change the Ethereum code, hoping to recover the funds. To this end, Ethereum makes a hard fork and makes a backward incompatible change, so that all Ethereum coins, including those occupied by hackers, return to their original places
it is necessary to introce what is hard bifurcation. blockchain is not an unchangeable program. It will also upgrade system rules and change some codes. In the process of system upgrade, if some nodes do not accept the upgrade, the whole network can not reach a unified consensus. At this time, two blockchains will appear, which is called hard fork. The hard bifurcations of bitcoin that will take place on August 1 are the same. We will not explain them here
some people in Ethereum do not agree with the hard bifurcation. They think that the essence of blockchain is decentralization, openness and unchangeable, which is its value, so they refuse to modify transaction records. The website of Ethereum classic wrote: "the way Ethereum foundation responds is probably the worst. We believe that the original version of Ethereum, as a world computer, will not fall down, it runs an irreversible smart contract." By remaining in the unchanging version of Ethereum to continue mining, these people are protecting these values in their own way. It sounds like something to do with feelings
as the hard fork is carried out openly through the blockchain, although there are objections, as more and more people support the hard fork, Ethereum's hard fork succeeded on July 21, 2016< At present, ETH, the "official" version of Ethereum, is maintained by its original developers; Ethernet classic etc is maintained by a new team. This is the first time that the mainstream blockchain has changed the transaction records by forking in order to compensate investors. People who hold ether money before the split will hold both Eth and etc after the split, and ether money stored in exchanges or online wallets is no exception. The total value of the two markets derived from this bifurcation is more than US $1.2 billion
at present, more and more Ethereum miners have invested a lot of computing power in this classic blockchain, and the trading volume of etc has increased not only because of the consistency in concept, but also because they have seen the value of protecting transaction security and winning relevant mining awards. One or two days after the introction of Ethereum classic, the hash rate of Ethereum network is 544gh / s, accounting for 13% of the total amount of Ethereum network hash
"currency exchange" was the first exchange to accept the currency of etc. subsequently, most of the exchanges supporting eth began to support etc. Okcoin opened etc recharge on July 15, and formally launched etc spot trading on July 17

Li Yuanba is a fictional character in shuotang, xingtangzhuan and Wagang hero< in shuotang, Li Yuanba is the first Liangshan hero in the world, and the first of the eighteen Liangshan heroes in Sui Dynasty the arms are like the hands of Dan. A pair of hammers weighs 800 Jin. Li Yuanba in the book is called Linfan, the golden winged bird of the Mirs in the realms. He was granted the title of King Zhao by Emperor Yang and called the king of Zhao in Xifu. The description of him in the book is as follows:

< blockquote >

at the age of 12, he was born with a pointed mouth and a red hair in the middle. Wearing a black gold crown, his face looks like a sick ghost; Bony and powerful. With four elephants in both arms, he is more brave than Xiang Yu, the overlord of Western Chu in Chu Han Dynasty. A bucket of rice is ten jin of meat. With two hammers, each weighs 400 kg. The two hammers are 800 kg, which is as big as a jar. No one can beat you when you ride a cloud

Generally speaking, the prototype of Li Yuanba is Li xuanba

Li xuanba (599-614), whose name is Desheng, was the third son of Li Yuan, Emperor Gaozu of the Tang Dynasty. Li Jiancheng and Li Shimin were the same mother and brother of Emperor Taizong of the Tang Dynasty, and Li Yuanji was the same mother and brother. His mother was the Dou family, the empress of Taimu, who was Li Yuan's wife. Yuan is Xuan. The two characters can be used in general. To avoid Emperor Kangxi's taboo, the Qing Dynasty changed Li xuanba in historical records into Li Yuanba. Li xuanba is close to Li Yuanba in terms of his real identity and age, seems to be a well deserved prototype historical records:

< blockquote >

you Bianhui, born in the 10th year of Daye in Sui Dynasty, was 16 years old and had no offspring. During the reign of Wude, he was granted the title of King Wei Huai and presented it to the director of Qinzhou and Sikong. Ethereum Zong Zi Tai was the king of Yi, worshipping him and burying Zhiyang. Later, he moved to Vietnam and became the heir of Baoding City, King qiongzi of Xiping. Hong, no children, except the state

negligence means that Li xuanba argued about Hui from a young age. Ten years after the great cause of the Yuan Dynasty, Li xuanba passed away. He was only 16 years old and had no children. During the reign of Wude (618), after the founding of the Tang Dynasty, Li Yuan, Emperor Gaozu of the Tang Dynasty, was granted the title of King Wei. He was also the director of Qinzhou and Sikong. In the fourth year of Wude, Li Yuan, the emperor of Tang Dynasty, took Li Bing, the fourth son of Li Shimin, the king of Qin, as the king of Yi and the heir of Li xuanba. Li xuanba was buried in Zhiyang. There are so many historical records about Li xuanba. Because he died young and only lived more than 16 years old, he did not do much that can be recorded by historians

According to the historical records, Li xuan was prudent and generous, skilled in martial arts, modest and polite, prudent and generous, modest and polite, of course, which was not in harmony with Li Yuanba's style it is more consistent with the formation of young people who die early Li xuan followed Tang Taizong for several times in his crusade. Tang Taizong deeply regretted the death of his cousin and said to people:
< / blockquote >

< blockquote >

he often followed me in his crusade. Seeing my deep enemy camp, he was envious that if he wanted to follow my example, he would do so

< / blockquote >

and cried bitterly for Li xuan's sacrifice. The reason for Li xuan's sacrifice is his discord with his deputy general Shi Longsheng. At that time, Li xuan led the light cavalry to rush into the enemy's camp first, and ordered Shi Longsheng to lead his elite troops to follow. Shi Longsheng sat back and watched the success or failure, and said to his confidants:

< blockquote >

I received the imperial edict written by the emperor, which said that the king of Huaiyang was a pet dog, the army operations were authorized to entrust the old man to me now Huaiyang King attacks with clumsy mouth and tongue. If he attacks with clumsy tongue, he will not succeed together and cause destruction. it can't compare with using Huaiyang king as t to lure his opponent. If Huaiyang king doesn't succeed, his opponent will race forward. If I stick to myself, I can defeat my opponent

< blockquote >

in this way, Li xuan went deep into the enemy camp alone and lost his life. Shi Longsheng led the troops to prepare for the battle ahead of time, but the soldiers had no morale, so the Tang army was defeated. There is no accurate direct evidence to prove whether Shi Longsheng has written an edict that emperor Gaozu Li Yuan of the Tang Dynasty appointed him as the specific commander, but at least the trick of "using Huaiyang king as t to lure opponents" is a complete failure

< / blockquote >

therefore, there is a conspiracy about the mystery of Li xuan's death, in which Shi Longsheng's behavior is very big. However, as a leading general, Li xuan did not follow Sun Bin's standard of "immobility like a mountain" and was eager for success, so he had some obligations. Fortunately, his brave and fearless, with a unique brand image, has left a mark in everyone's memory
