Decentralized insurance picture
what is centralization
the so-called centralization means "ownership" or ownership by the company. For example, Tencent's q-coin, which is issued by Tencent, is a kind of centralized electronic currency, including the total amount and the issuing method, is supervised and controlled by Tencent. You can use it, trade and go shopping, but you always have to operate in the framework of Tencent, and the final right of interpretation belongs to Tencent
the issuing mode of bitcoin is preset by the program and encryption algorithm, and runs on multiple nodes all over the world. No one or organization can modify it (everyone has his own account book, so it is impossible for one person to control everyone's account book at the same time. If there is such a technology, why should it be so complicated, If you want to blackmail money into your account, you will be the richest man in the world. There is no one left, And it is not controlled by any single person or organization
take an example: for example, Lao Zhang borrows 100 yuan from Lao Li, but Lao Li is afraid that he will default, so he asks the village head to do notarization and write down the account. This is called centralization. But if you don't find the village head, you can use the loudspeaker to shout in the village: "I Lao Li lent Lao Zhang 100 yuan! Please put it in the account book. "We all put this account in our own account book. This is called decentralization
anyone who transfers money between them will release information through loudspeakers. After receiving the information, everyone will record the transaction in their own account book. With distributed ledgers, it doesn't matter if Lao Zhang or Lao Li's ledgers are lost, because Lao Zhao, Lao Ma, Lao Wang and other families have ledgers
the main advantages of blockchain are that it does not need intermediary participation, the whole process is open and transparent, and the cost is low, and the data security is high
at present, blockchain is in a stage where everyone talks about blockchain, but can't perceive its actual technical charm. Since 2017, it has graally come into our sight, and we have graally realized that bitcoin is more fierce than real estate speculation (the price of mining machinery has skyrocketed! The news is on the screen But I still don't know
so, in which fields can blockchain be applied, what kind of changes will it bring to our future life
the core key: everyone has an account book, everyone has an account book, and the information recorded in each person's account book is consistent and synchronous, and the information is completely transparent. If it is fake, it will be the public enemy of the whole people, which greatly increases the cost of data fraud
core key 2: decentralization, which does not need a central system to manage data, prevents some people from changing data and damages the interests of the majority of people
Application:
1. Account security and privacy protection: currency transfer, exchange, payment system. Blockchain can help prevent data manipulation and fraud, prevent distributed denial of service attacks (DDoS), and effectively protect users' network privacy. Key words: anti counterfeiting, anti-counterfeiting, loan payment
2. Copyright regulation and interest disputes: for example, when a song is downloaded, from the author to the procer and then to the singer, they can get payment in real time through the blockchain, without having to wait for a long time like the traditional way, or even get no reward e to right disputes. Instead of waiting for publishers to provide royalty checks, creators can freely control the process from publishing to payment through blockchain application. Key words: real time receipt, no property dispute
3. Internet of things + artificial intelligence: the intelligent devices in the Internet of things based on the blockchain will be used to monitor the real-time situation of urban infrastructure such as bridges, roads, power grids, etc. the blockchain can connect these intelligent devices together for unified management to help them monitor more efficiently. This will help people better understand how to build a smart city in the future. Key words: unified monitoring, intelligent city
4: proof of existence: in life, once you are asked to prove that you are you, that your mother is your mother, that you have never been married, that the house belongs to you, and so on, things seem very simple. Once it falls on you, it is a great trouble. The application of blockchain technology can perfectly solve the above embarrassment. At that time, all the information that belongs to you will be recorded accurately and can not be tampered with. No one has the right to change it. When the technology develops to a certain stage, birth certificate and marriage certificate may be recorded on the blockchain. Keywords: no keywords
in addition to the application scenarios mentioned above, blockchain technology can also be applied to e-commerce, data storage, logistics and other fields. As long as we grasp the characteristics of blockchain technology, it will become easy to understand.
because those who come in after mobile phone mining will be cut leeks
precautions:
1. In the past two years, various myths about blockchain "overnight wealth" have been constantly staged, and "mining" cryptocurrency has become a new trend of wealth, and mobile phone mining is becoming more and more popular
2. There will be special mining machines for real mining. After all, every mining machine is not cheap now. Mobile phone automatic mining can be obtained at a very low price. What you dig is not bitcoin. Basically, the counterfeit coin you send is not worth money. At that time, you will still be cut leeks
Bitcoin is a virtual cryptocurrency based on decentralization, peer-to-peer network and consensus initiative, open source, and blockchain as the underlying technology. It was proposed by Nakamoto in 2008 and born in 2009
bitcoin does not have a centralized issuer, which is generated by the calculation of network nodes. It can be bought and sold on any computer connected to the Internet, and has a strong scarcity
The first surprise is that I know that "altruism"
giving advice, getting feedback and readjusting suggestions day after day will soon make the economy in a dilemma. I also need to live. It's really hard to rely on others to reward those soft girls, so I want to do something. I started a buddy group with online partners, and started planning for some enterprises, serving well-known chain restaurants, shaking MCN tiktok, TOP3 in children's programming field, etc. p>
but every case is not very easy. It requires a strong team cooperation ability. Everyone in the online team is trained in planning and operation, and the communication efficiency is low. It is much more convenient to do some skills by themselves than outsourcing. The team must have someone to do it, so I was forced to learn how to build a website, design pictures, aff and so on. Although the learning process was very painful, looking back on myself now, I was really surprised
< H2 > the second surprise, I became a "dragon"telecommuting for more than half a year, I gained 30 jin, my mother said to me with a smile, you are going to be a pig son. My object also patted my little belly and laughed happily
working at home for a long time makes my body not only fat, but also a little uncomfortable. The good body shape I've developed in my line of work has disappeared completely, leaving a body fat wrapped with only the remaining muscles, and shaking it twice from time to time, as if mocking me: hey, you fat boy
man, it can't work. Look in the mirror, it's a rowing boat! Thick beard all over the face, huge face full of mirrors, strong arm a top two, all this tells me, to! Minus! Fat! It's over! In order to make myself more healthy, I run a fitness card in the gym every two days for three or five kilometers. The effect is very obvious. Although I didn't lose more than ten kilograms at a time, I restrained the soaring of my weight, and even lost a little. It's good! At the same time, the soaring weight also means that my life is unrestrained. I began to consciously divide my work and life into three parts: shaving when my beard grows, going out for a walk with my partner after dinner, going out to explore the shop together, going back to my parents' house to chat with my mother from time to time... All these things I would not do even when I worked in the company, and graally adjusted the balance between work and life, It's good that my happiness is soaring
< H2 > the third surprise, I understand that "balance"telecommuting brings me many surprises, such as "pragmatism", "team", "contract spirit", "self-control" and so on. I believe that telecommuting will bring me more surprises in the future. Now I have set up my own telecommuting team. I don't plan for others, but do it myself. Telecommuting is a trend. In the future, enterprises need this ability too much. At the same time, I think I will telecommuting in the future, and even become a digital vagrant
once the motion was put forward, it caused a lot of attention and Discussion on the Internet. The goal of "building a well-off society in an all-round way" put forward by Wang Xuekun is to let farmers over 65 enjoy the fruits of a well-off society in an all-round way. For several generations of hard-working farmers, retirement has been their distant dream. If they can "wash their feet and go to the fields" after the age of 65, receive the state pension and enjoy their old age life comfortably, maybe this is the spring of Chinese farmers< In fact, this is not the first time that Wang Xuekun's proposal has appeared in the "two sessions". During the two sessions in 2018, Zhang Yazhong, member of the National Committee of the Chinese people's Political Consultative Conference, once said that as practitioners of the primary instry, compared with other instries, farmers should also retire and change jobs. Two years later, the "two sessions" made such a sound again. With such a strong response, it seems that the time is almost ripe to solve the problem of providing for the aged, and farmers' wishes may come true< br />
for farmers, retirement at the age of 65 means that they can enjoy their old age like city people. In this way, old farmers will no longer have to farm. We can see that in some rural areas, not to mention those over 60 years old, and even some 70 years old, because of the pressure of life, they still have to go to work in the fields, still in order to earn money. Until the day when they can't work on the Kang, they will give up their "work" all their life. It's self-evident that farmers suffer from hardship and tiredness
most netizens also supported and agreed with the proposal, praising it as a "warm" proposal and focusing on a major and realistic social problem. For Chinese people, farmers have always been a word full of emotion. How many generations of Chinese people have passed on? Who is not a peasant? So the question is, if the state gives pension to farmers over 65 years old, how much does it need to pay each month to make a living< br />
e to different levels of economic development and consumption, it is impossible to unify the standards. However, we can refer to the local minimum living standard and take corresponding supporting measures to meet the reality and be sustainable
as far as the whole country is concerned, e to the different levels of economic development and consumption in different regions, there are also great differences in the minimum living standard. For example, the minimum living standard for urban and rural residents in Shanghai is 790 yuan / month, and that for Beijing is 710 yuan / month. For example, in places where there is no integration of urban and rural minimum living security, the minimum living security standard is 540 / month in Tianjin and 290 / month in Zhengzhou. The reason why there is such a big difference is mainly related to the level of local economic development (fiscal revenue capacity) and consumption level. Therefore, the monthly pension payment of the rural elderly over 65 years old must be determined according to the local economic development level and consumption level< br />
farmers' friends have been dealing with land all their lives, especially the older ones. If they can live a more considerate and warm life in their old age, it is also the need of building a well-off society in an all-round way. As the proposal is still under discussion, the specific situation is not known. However, the welfare policy for the rural elderly over 60 years old has been implemented. There are old people's friends at home. Don't miss them.
