The significance of blockchain receivables to risk control

1.

Although driven by the influx of capital and talents, the blockchain instry ushered in rapid development, but as an emerging instry, the frequent warning of its security vulnerabilities caused people to worry about the risk of blockchain

Yu Kequn, director of the national information technology security research center, pointed out that the emergence of blockchain has brought people a lot of expectations for privacy exposure, data leakage, information tampering, network fraud and other issues. However, there are still many challenges in the security of blockchain

Li Bin, assistant director of China Information Security Evaluation Center, analyzed that the current blockchain is divided into three types: public chain, private chain and alliance chain. No matter which type, it faces security challenges in algorithm, protocol, use, time limit and system. What is particularly critical is that the current blockchain is still facing 51% attack problem, that is, nodes can successfully tamper and forge blockchain data by mastering more than 51% of the network examples

it is worth noting that in addition to external malicious attack risk, blockchain also faces the threat of its endogenous risk. Yu Kequn reminded that how to build a complete security application system around the equipment, data, application, encryption, authentication and authority of the application system of the whole blockchain is an important problem that all parties must face

Wu Jia also analyzed that as an emerging instry, employees in the blockchain instry are lack of safety awareness, which leads to the low safety factor of the software and hardware related to the blockchain and a large number of security loopholes. In addition, there are many ecological links in the whole blockchain. In contrast, the strength of the relevant security employees is scattered and it is difficult to form a joint force to solve the problem. A systematic solution is needed to meet the above challenges

2. Forget the private key, the mnemonic note lost... This is the most basic. When it comes to the essence of investment, it is the investment risk caused by the fluctuation of currency price. GRE global risk trading all specialized insurance can be bought to avoid the risk of digital money market.

3. Many relationships between people are based on trust, such as friend relationship, cooperation relationship, transaction relationship, etc
take trading activities as an example. In the past, the two sides who did not trust each other usually chose an intermediary to guarantee a transaction. In the mobile Internet era, we chose Taobao shopping because Alipay provided us with an intermediate guarantee. We chose to drop dripping because it provided us with information matching.
however, these intermediaries are centralized and have their own interests. Sometimes they are not so reliable and trustworthy. Theoretically, Alipay's centralization of accounting has been artificially falsified. Part of the reason for Didi's troubles is that they only think from their own standpoint
what blockchain does is the machine of trust, which replaces the role of trust intermediary with code, ensures the fairness and justice of the whole system through consensus mechanism and distributed accounting, and provides a trust without trust
for example, in the future, people can abandon the intermediate platform and realize point-to-point docking and free trading through blockchain. Shopping does not need to go through an intermediary, and taking a taxi does not need to go through Didi. In this way, we can really achieve "no middleman to earn the price difference" and rece the cost.

5. Of course, the butterfly effect exists, but your experience is not just the butterfly effect
the butterfly effect is about a butterfly in South America flapping its wings and eventually causing a storm in North America through a series of chain effects. It emphasizes that a very small change will have a tremendous impact on the whole system after a period of time. This concept was put forward by a meteorologist after studying the weather forecast for a period of time when the weather forecast was not developed decades ago, because he found that he could not accurately forecast the weather for many days in any case, Even a very small change can make things completely deviate from the expected track after a period of time
far away. Tell me about your troubles. Although I don't know that you are the "bad self" now; Is it because of your mother's behavior when you were a child, but I can be sure that it must have a great impact, which I deeply understand
since I was a child, I have been very smart, mischievous and playful, but my academic performance has been very good, so my mother is very proud when she talks about me with her friends. Unfortunately, my mother was a very irascible person, so I suffered from domestic violence from childhood to the age of 16< In fact, there are three stages of rapid development in a person's life. About three years after the age of two, it is a period of rapid development of the brain's logical cognition, language and image processing ability. Since then, the child has changed from an instinctive animal who can only eat and drink Lhasa to a child who can speak, sing, dance and shout for his parents. The next step is from the age of eleven or twelve to the age of five or six. This period of time is particularly concerned. Why? During this period of time, people began to have an ability called "Introspective intelligence". They would often think about what kind of person I am and what I came to this world for. They also became vulnerable and rebellious, which was the focus of conflicts between parents and children. This period is the shaping stage of children's EQ and character. The last period of high-speed brain development is about 18 to 22 years old, which is the last climax of the development of Comprehensive Brain ability. After the age of 22, people's brain development has basically taken shape and started to reach the peak of their life. However, it is a pity that many young people have played in the golden age from 20 to 30, and only when they wake up at the age of 30 do they have to think about starting a family. Let's not show this for the time being. Why do I say this? What I want to say is that what kind of person a child will become is closely related to the ecation of his parents. Because when a child's brain is not shaped, it is his parents who get along with him most. In the process of children's growth, the role of parents is even decisive. This is not a small action like a butterfly flapping its wings in the atmospheric system, but the hands of pottery makers
even though my academic performance has been very good, but I have not been very disciplined, like mischievous, do not do homework at home, often running around to play, so my mother this kind of parents who discipline their children very strictly and use violence to solve problems, the impact on me is really very big
when I was 13 years old in the second year of junior high school, I had already suffered from a considerable degree of depression. In fact, I didn't see a doctor at that time, so why did I know? Because at that time, in addition to feeling depressed and cranky, I had physical symptoms, such as insomnia, unexplained dryness and heat, sweating all over the body, getting wet all over the body, sometimes chest tightness, shortness of breath and so on. But after the third day of junior high school, I changed my living environment. Although I still live with my mother, my symptoms have improved. Until some time ago, I went to the mental health center for half a month because of insomnia. The doctor told me that I had mild depression. I found out that the disease had not improved after seven years
I said this to tell you the answer to your question. Is your life influenced by your parents and how much. I believe you can probably get the answer from my above words
but it is worth noting that parents, after all, are parents, which is not our choice. We should not blame our parents because they play a less active role in our life. Today I can write such a big article for you without any emotional fluctuation, which proves that my attitude towards my mother is not the same as that of the past. At that time, I wish I was a motherless child. It's true that adolescent children are like this. This is their personality shaping period. At this time, how you treat your children, the children will treat you, and the influence will last for a lifetime. Some of them are serious, and the impact is even worse. Because parents beat and scold their children, their children become more rebellious, and their parents beat and scold their children more severely, and they still can't figure out why I'm good for them, and he's still so ignorant. But the child is like this, he also knows what he is doing is wrong, should not skip class, should not secretly go to the Internet bar, but in the face of such strict parents, his mood is against the parents, so the more he plays, the more disobedient he is. Sometimes it may work for a period of time if he plays too hard, but in the end, it will cure the symptoms rather than the root cause, and aggravate the contradiction
I used to feel incredible and furious when I saw the news that children killed their own parents. But later on, as long as anything happens, there must be a reason. Children can't be born to want to kill their parents. There is a saying that one slap can't make a sound. It's always because parents have a very bad attitude towards their children ring their development, so children also treat their parents in a bad way, so the vicious circle is getting worse and worse, which eventually leads to tragedy
at that time, I had such a feeling about my mother that I hated her and she hated me. From the very beginning, there was a contradiction because of the real principle of whether to do homework or not, to the later because of the trivial matter of whether to put pepper in some fried vegetables
what I don't know is that at that time, I was very irritable and sometimes hurt my classmates and friends. But at that time, I didn't think so. I felt that as long as I didn't see my mother and went to school, I got along well with everyone. Although it was true, I ignored that sometimes I lost my temper with my classmates, which was totally unnecessary. Most of the time is playing the game, when my teammates do not perform well, I will try my best to complain, but I don't realize how bad my attitude is. This is a very bad situation, even if I don't do well, and I don't know how bad I am
fortunately, after I went to university, I graally understood a lot, began to understand a lot of things, and began to become a better person. In fact, it has something to do with my good academic performance, reading a lot of books and being very fond of thinking
a lot of things that seem to be useless after learning, things that seem to have no influence after experiencing, and the Daze time when we think for a long time but don't want to understand anything, in fact, we have been shaping ourselves
how to be a better person< br /> Keep learning and thinking

6. Ivan (Ashton Kutch) is a college student who looks very ordinary, but recently he seems to have a lot on his mind. There are always pictures of unfortunate childhood looming in my mind, just like the black hole theory in physics, no matter what it is, I can't find its origin. These terrible and vague meetings have always tormented Ivan's thoughts and life. I can only vaguely remember the names of my friends: Kailei (Amy Smart), LiNi (Alton Hansen) and Tommy (William Lee Scott). However, for his relationship with him and the things he has experienced together, he can only rely on some fragments to connect them. For the complete things, he can't recall them. Ivan was coached by a psychologist in his childhood, who advised him to record everything that happened every day. In this way, by the time he was in college, Ivan had already written down several big diaries., Whenever he looks at these things he has experienced, a terrible idea always comes to his mind. He always thinks that what he did in his childhood hurt his friends and classmates. But he recalled that when he pursued his classmate Kailei, some of the warmth and sweetness in his life filled Ivan's thinking. He decided to find his own childhood happiness. He entered his body and environment in the same year with his present consciousness, hoping to change the past, find back the friends he hurt and lost contact with, and enter into a love again with the girl he loved. But he was wrong, but when he returned to his present "self", things became much beyond his expectation, and many things became inconceivable. No matter what friends he hoped for, love or problems he didn't find in the show, all burst out. He realized that this behavior failed. If he continued, life would be on the verge of collapse. Ivan, who has taken the first step, has chosen to go back to the past and change the status quo a little bit. But just like the butterfly effect, some factors in the environment that he can't estimate are changing the direction of things at the same time. I don't know if it's all the good things in the imagination that wait for Ivan, or whether it's going to continue to subvert life and bring him to a state of collapse Behind the scenes 1. What is the butterfly effect? Why should such a suspense film be named after a theory? These questions must be your initial reflection after seeing the title. The butterfly effect is a problem and hypothesis discovered by American scientist Lorenz in an accident. In a calculation, because the fourth decimal place of the initial input data is rounded, the output result deviates from the last one rapidly, and the similarity of the two curves before and after the calculation is completely disappeared. Twenty years later, Lorenz raised this issue in a speech, which is called "Butterfly Effect". He believes that in the process of atmospheric motion, even if the errors and uncertainties are very small, it is possible to accumulate the results in the process and enlarge them step by step to form a huge atmospheric motion“ The meaning of "Butterfly Effect" is "sensitive dependence on initial conditions", which was later extended to a seemingly unrelated, very small thing, which may bring great changes. This kind of scientific theory can be attributed to the two screenwriters Eric Blaise and J. markye. Although they are the first to know the feature film, they should not think that they are the new generation. They are the golden playwrights in the film and television instry. In that year, the "dead end station 2" has highlighted their advantages and strength in the plot, The "Butterfly Effect" directed this time can be regarded as a work carefully planned by two people. We have made great efforts in both plot and plot setting. We should really believe in the ability of the two "new" Directors to control the film. 2. It's said that Ashton Kutcher is the latest representative of Hollywood's handsome little boy. It's no wonder that in the recent series of roles he plays, handsome little boy accounts for more than half of the total. Coupled with his love affair with the old female star Demi Moore, he quickly occupies a prominent position in the entertainment space. However, he should be the kind of actor who is not satisfied with the status quo. Just like Tom Cruise, he is always looking for opportunities to prove his strength. He is not only satisfied with showing his face in front of the screen, but also impresses others. This "Butterfly Effect" gives Kutcher a good chance, in which he not only has a beard, but also becomes decadent and confused. Speaking of his role, Kutch said: & quot; Ivan is a man who has lost himself& quot; His life was shrouded in the shadow of childhood trauma. At the end of the film, a series of things happened, which finally made him understand that it was not necessary to find out what he was doing& quot; It seems that from the "that &" 39; 70s Show，Punk' d Along the way, the Iowa boy is moving in the direction he yearns for. Whether it's his original image of cream or gossip with female stars, we should be glad to see his efforts and achievements in his romance career. It seems that Hollywood will add another actor. If I ask you a question: what kind of horror movies are most afraid of? It is estimated that most people will answer: psychological terror. Indeed, with the continuous development of new technologies and new technologies, the terrorist environment that can be displayed by using technological means has basically reached the limit. So now the films involving horror and suspense are developing in the direction of excavating the inner fear. The butterfly effect is a good example. It uses the hero's thinking activities to drive the audience to experience such and such scenes and events together, which makes the audience feel ups and downs with the development of the plot. So whether you are interested in the name, content, or hero of the film, you should start the spiritual journey with Ivan in the film.
