When the global financial crisis broke out in 2008, someone published a paper under the pseudonym of "Nakamoto Tsung", describing the mode of bitcoin

many bitcoin players are attracted by the fact that bitcoin can not be issued at will. Contrary to the attitude of bitcoin players, economists have a polarized attitude towards the fixed amount of 21 million bitcoin

Economists of Keynesian school believe that the government should actively regulate the total amount of money, and use the tightness of monetary policy to timely fuel or brake the economy. As a result, they believe that bitcoin's fixed aggregate currency sacrifices its adjustability, and worse still, it will inevitably lead to deflation, thereby harming the overall economy. Austrian economists hold the opposite view. They think that the less the government intervenes in money, the better. The deflation caused by the fixed amount of money is not a big deal, even a sign of social progress

bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system. Bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network will get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as a reward to reward the person who gets the answer

when bitcoin was born in 2009, each reward was 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the bounty will be halved to 25. When the total amount reached 15.75 million (5.25 million new output, or 50% of 1050), the bounty was further halved to 12.5

first of all, according to its design principle, the total amount of bitcoin will continue to grow until it reaches 21 million more than 100 years later. But the total amount of bitcoin will grow very slowly in the later period. In fact, 87.5% of bitcoin will be "g up" in the first 12 years. Therefore, in terms of the total amount of money, bitcoin will not reach a fixed amount, and its total amount of money will continue to expand, although the speed is getting slower and slower. So it looks like bitcoin is the inflation currency

However, the judgment of deflation or inflation is not based on whether the total amount of money is decreasing or increasing, but on whether the overall price level is falling or rising. The rise of overall price is inflation, and vice versa. In the long run, the issuing mechanism of bitcoin determines that the growth rate of its total amount of money will be far lower than that of social wealth

Economists of Keynesian school believe that the continuous decline of prices will make people tend to postpone consumption, because the same dollar can buy more things tomorrow. The rection of consumption will further lead to shrinking demand, unsalable goods, lower prices and a vicious circle of "deflation spiral". Similarly, the deflationary currency itself can appreciate even if it is not deposited in the bank (the purchasing power becomes stronger and stronger), people's willingness to invest will increase, and social proction will fall into a downturn[ 5] Therefore, bitcoin is a currency with deflationary tendency. In bitcoin economies, commodity prices priced with bitcoin will continue to fall

bitcoin is a kind of network virtual currency with limited quantity, but it can be used to cash out: it can be converted into the currency of most countries. You can use bitcoin to buy some virtual items, such as clothes, hats, equipment, etc. in online games. As long as someone accepts it, you can also use bitcoin to buy real-life items

4. Human flesh search is a kind of network query mechanism that uses human participation to provide pure search engine information. In short, the so-called "human flesh search" is a network way to search other people's privacy information. Obviously, human flesh search inevitably involves personal privacy, and the disputes about human flesh search are also legal issues. What legal issues does human flesh search touch? How can legal science diagnose human flesh search? From the definition and operation practice of human flesh search, the main motive of this engine technology is to mine other people's privacy information, which is also the main function of human flesh search. Therefore, human flesh search will first touch personal privacy. The right of privacy is one of the specific personality rights enjoyed by natural persons (citizens), which takes personal natural information and behavior information as the right object. The right to privacy is protected by law and shall not be infringed upon by others. The main forms of infringement of privacy are prying, leaking, spreading and abusing. Once the right of privacy is infringed, it constitutes a tort and should bear the corresponding tort liability. The activity mechanism of human flesh search is as follows: once the human flesh object is found, the Internet people can search its privacy information as widely as they can, and then provide search convenience for users. It can be seen that the privacy of those who are "human flesh" may be infringed
What's abominable is that human flesh search not only discloses other people's privacy, but also fabricates facts, insults, slanders, exaggerates and denounces human flesh objects. Such behavior can easily touch other people's right to reputation. The right of reputation is also one of the specific personality rights enjoyed by natural persons (citizens). It takes the rection of social evaluation as the judgment standard of infringement, and the main means leading to the rection of social evaluation are insult and slander. In the process of human flesh search, many netizens, out of indignation, describe the object of human flesh search poorly and speak rudely, and a large number of abusive and insulting words pervade the Internet. This will cause the adverse consequences of reputation damage to the parties. Whether the right of privacy is violated or the right of reputation is damaged, it will inevitably cause the loss of personality to the protagonist of "human flesh gate"

the harm of human flesh search is not limited to the direct infringement mentioned above. What's more serious is that with the help of human flesh search information, intrusive behaviors are implemented in reality, such as making harassing phone calls, posting newspapers with indecent words on the door, etc. Obviously, the harm of human flesh search has spread from cyberspace to the real world. Such a series of infringement followed, and finally staged China's "first case of human flesh search", the victims eventually sued the perpetrators and related websites in court, and finally won[ 1]

it is not difficult to see that human flesh search can almost be equated with tort. Many people even call for severe punishment of human flesh searchers, and even advocate banning human flesh search. It is true that legal science can diagnose specific cases of human flesh search, and can give legal technology analysis and value evaluation, but the emergence and development of human flesh search and its practice seem to prove that human flesh search is not only a legal problem. In the period of social transformation, especially the information explosion in the Internet age, people's curiosity about new things and the psychological depression accumulated by the fast-paced life are easy to break out instantaneously. Human flesh searchers would rather bear the pressure of legal risk and public opinion condemnation, but also play the Internet carnival that hurts the parties, and experience the stimulation brought by human flesh search game

despite the rapid development of human flesh search in China in recent years, foreign human flesh search has been growing healthily and soundly. It not only has considerable commercial profits, but also consciously abides by the legal rules, making human flesh search develop rationally along the road of legalization and commercialization, Its users naturally regard human flesh search as a normal and necessary human interactive help service. In contrast, in China, when people hear about human flesh search, they don't seem to regard it as a good thing at all. In most people's eyes, human flesh search may be a bad online game or a boring online farce. The reason why human flesh search is so biased is that the search engine is almost at the edge of the law

in fact, as a new thing, human flesh search should not be knocked down. We should dialectically analyze the advantages and disadvantages of human flesh search and comprehensively understand its impact on people and society. As a way to provide information, human flesh search undoubtedly provides convenience for Internet users in many aspects. With the development of society, it is a legitimate right for people to obtain and possess a certain amount of information, which is also an internal demand of people as a member of the social system. In the field of human rights and public interests, people not only have the right to know, but also have the right and obligation to exercise social supervision and public opinion supervision. When the infringement and even the criminal act or the events that affect the national interests and social interests occur, it is necessary to verify and condemn the parties. At this time, with the help of human flesh search, by absorbing the insiders to participate in the shortcut provided by information, the parties are often easy to be accurately "human flesh" out. The positive function of human flesh search is not only reflected in the supervision of the perpetrators of the search, such as looking for relatives and good people to find stakeholders in the action, human flesh search can also perform extraordinary, with the help of public power, effectively screen information resources, show the search results that people need. In addition, from the development practice of human flesh search, its function has not only been limited to the search of people, but also penetrated into the search field of other information, gathering netizens' enthusiasm and displaying its search skills

if we say that as a network search method or technology, human flesh search shows its value because of its positive functions, then people's use of human flesh search may make its own functions deviate from the track and slide into the negative field which is easy to cause condemnation and resentment. Judging from the cases of human flesh search that have happened in reality, the reason why human flesh search has encountered a lot of criticism is not that human flesh search itself has inherent infringement toxin, but that the operators of this game ignore the legitimate rights and interests of human flesh search objects, and consider the value of the event itself and the legitimacy of the rights and interests of search objects, It seems that netizens have shifted the balance of interests to the degree of condemnation of the event itself, and without thinking, they think that the value of condemning and exposing human flesh search objects is far more important than the protection of their legitimate rights and interests. At this time, the moral trial goes beyond the legal bottom line. When more and more people regard themselves as moral judges, the rights and obligations endowed by law are completely ignored. As a result, once encounter human flesh search events, often instantly gathered a large number of people, in full swing to expose the abominable face of human flesh search

at this moment, the search objects who have been collectively investigated and tried are undoubtedly suffering from privacy disclosure and rights erosion. The culprit of this result is not human flesh search, but all kinds of tort mentioned at the beginning of this article. In other words, it is not the human flesh search itself that leads to infringement, but the human flesh searcher's behavior angers the victim. To be fair, human flesh searchers are not born with infringement motivation. In many cases, human flesh searchers may not do it intentionally, but connive at the madness of human flesh searchers because of the lack of guidelines for their behavior. This is exactly the case in reality. The laws and regulations directly related to human flesh search are in a blank state. In case of infringement cases caused by human flesh search, we have to apply the general norms of tort liability. It can be said that human flesh search is drifting away from the edge of the law

is the "human flesh search", which is on the edge of the law, a ban or a legislative gap[ 2] According to the previous interpretation of the positive function of human flesh search, combined with the healthy operation practice of foreign human flesh search, starting from the development space and actual needs of human flesh search in China, rather than stifling this new thing by banning human flesh search, it is better to reasonably regulate the behavior of human flesh search through scientific legislation. This is almost a consensus[ 3] Moreover, from the perspective of the current legal norms, it is not lack of legal basis to identify the composition of tort. From the perspective of the general adjustment function of law, China's current law is not powerless in regulating the tort of human flesh search. The first case of human flesh search, which has made a judgment and has been partially implemented, also invokes the current tort legal norms. However, human flesh search as a type of network infringement, because of its own particularity, can not but urge legislators to pay special attention to its responsibility distribution

in this regard, an effective way should be to reasonably define the liability space of human flesh search infringement. In terms of the liability involved in human flesh search infringement, both the website and the specific behavior of human flesh search are likely to be responsible. However, the key to determine the subject of responsibility lies in the elements of responsibility. Therefore, it is very important to design the review system and imputation principle. According to the existing tort laws and regulations, the responsibility of the specific operators of human flesh search can be adjusted. There is no doubt that the organizers, privacy information providers and other forms of infringers who are in line with the composition of tort liability will be subject to tort liability. What kind of attitude should be adopted to determine the responsibility of the website? In view of the consideration of the overall development of the Internet and the positive function of human flesh search, it is more appropriate to impose the ty of ex post review on the websites involved in human flesh search. The so-called "post review" is mainly after the plaintiff considers that his rights and interests are infringed by the human flesh search behavior of the website and issues a relief request to him, or there is sufficient evidence to show that the website can take measures to stop it[ 4] It can be seen that the rule of review after the event contains the principle of fault imputation, that is, only when the website is at fault can it become the subject of liability and bear joint and several tort liability[ 5]

of course, from the perspective of legal norms of human flesh search, legislation should not only be limited to tort liability, but also make reasonable norms on the scope of application, search content, rights and obligations of relevant parties, supervision and management of human flesh search. Incidentally, some members of the Standing Committee and deputies of the National People's Congress have suggested that the criminal law should be used to regulate human flesh search and the criminal responsibility of the perpetrators of human flesh search should be investigated. The author does not agree with this. In recent years, human flesh search has just started in China, which is still a new thing. To deal with this means of network search, we should not completely eliminate human flesh search by means of strict prohibition, and we should not let human flesh search expand infinitely. However, as a legislative act, the regulation and adjustment of human flesh search behavior should be carried out step by step. According to the specific operation practice of human flesh search behavior, the corresponding legislation should be introced timely, instead of taking a heavy attack from the beginning, regarding human flesh search as a criminal tool and demoting the human flesh search actor as a "criminal". China's criminal legislation declares the principle of a legally prescribed punishment for a specified crime

7. Nowadays, pets are all the same, whether they are elites or not, and they can learn their skills after upgrading, which is much simpler than in the past. Think about that year, tiger king bangjialashi, blood bat, broken tooth, Rubus
now it's only divided into wild, cunning and tenacity, which are shown in the BB talent panel. It's better to use wild pets for level training. This kind of pets have high output, such as leopard, wolf, Velociraptor and so on. This kind of BB's talent skill level is high, such as wild call, frenzy, heart of Phoenix (2 lives). If you point out bloodthirsty, you don't need to feed it. There is no need to manage so much in the early stage, just use a leopard

if you have talent, don't think about group A, as long as you have strong continuity. The talent of the king of beasts is almost the same. If you practice level, think about the output first.

8. The purpose of studying this problem is to summarize the problems in the development of e-money in China, and put forward corresponding solutions in various aspects, so as to lay a theoretical foundation for the improvement of the application level of e-money in China.

9. Previous barter -- the emergence of money (shell money) -- the perfection of money (metal money, unified system and weight) -- the perfection and optimization of money (the emergence of banknotes and stocks) -- the evolution of money (from substance to number, that is, the emergence of capital account makes people's real money into a pile of numbers)

just this outline.... In these aspects

remember to give points.
