Decentralization to solve information asymmetry
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.
1. The central node grasps the information of distributed nodes
2. The sub nodes do not master the information of other nodes (centralization, non-public transactions)
moreover, the pain point of centralization is that the security of the system depends on the security of the central node, and the distributed node has no control over it.
Blockchain is a term in the field of information technology. In essence, it is a shared database. The data or information stored in it is characterized by "unforgeability", "trace in the whole process", "traceability", "openness and transparency" and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid "trust" foundation, created a reliable "cooperation" mechanism, and has broad application prospects
on January 10, 2019, the state Internet Information Office issued the regulations on the management of blockchain information services. In October 24, 2019, ring the eighteenth collective learning of the Central Political Bureau, general secretary Xi Jinping stressed that "block chain as an important breakthrough in core technology and independent innovation", "accelerating the development of block chain technology and instrial innovation". "Blockchain" has entered the public field of vision and become the focus of social attention
on December 2, 2019, the word was selected into the top ten catchwords of "biting words" in 2019

Application of blockchain Finance:
since 2016, the major financial giants have also carried out blockchain innovation projects to explore the possibility of applying blockchain Technology in various financial scenarios. In particular, Puyin group took the lead in creating a "blockchain +" standard digital currency
standard digital currency refers to the process of assets identification, evaluation, right confirmation and insurance completed by a third party organization, which is written into the blockchain through careful digital algorithm to form the standard corresponding relationship between assets and digital currency, which is called standard digital currency
in order to realize the great leap forward development of blockchain finance, promote the new development of China's economy, accelerate the circulation of global assets, and realize the dream of rejuvenation that has been struggling for generations, Puyin group will hold the Guiyang strategic development ceremony of Puyin blockchain finance in Guizhou on December 9, 2016
the meeting will discuss the realization of digital circulation of assets by blockchain, the financial transaction mode of blockchain, and the application of blockchain services and social public instry. This conference will mark the beginning of the application of blockchain finance and the change and development of the new financial ecology
okcoin, fire coin and bitcoin China are known as the three major bitcoin trading platforms in China
okcoin marketing is particularly good. At the same time, there is also the angel group of the devil three - Xu Mingxing, Zhao Peng and He Yi
of course, in the mining machinery instry, Avalon has always been the leader in this instry, and has created countless instry firsts.
there are many different opinions about the essence of the Internet in the instry, and they tend to the view that if one word is used to summarize the essence of the Internet, it is two words - "connection". The tremendous influence of the Internet in the past ten years is e to the higher connection efficiency of the Internet and the connection of more people, money and things, which has changed the business rules of the whole world
you can understand that the Internet connects people with information, Tencent connects people with people, and Alibaba connects people with goods. This is also the core reason why they are known as the three giants of China's Internet "bat", and their market value and instrial control are far ahead of the others. Because the essence of the Internet is connection, the Internet must have the characteristics of decentralization, deproctization, disintermediation and breaking the information asymmetry
the difference between the pre Internet era and the Post Internet era
the biggest difference is that the scope of connection has changed greatly. Take bat as an example: they connect people and information, people and people, and people and goods, which is a typical feature of the pre Internet era; In the Post Internet era, everything is interconnected. On the basis of the existing connection, countless terminals and hardware are connected to the Internet. Therefore, for home appliances and other terminals and hardware to be connected to the Internet will become common, while not being connected to the Internet will become unique. The change of connection scope will bring great changes to our way of life. With the support of big data, All things are connected to the Internet, and the era of all things intelligence is coming.

what is a blockchain? From the perspective of science and technology, blockchain involves many scientific and technological issues such as mathematics, cryptography, Internet and computer programming. From the perspective of application, in short, blockchain is a distributed shared ledger and database, which is decentralized, tamper proof, traceable, collective maintenance, open and transparent. These features ensure the "honesty" and "transparency" of the blockchain, and lay the foundation for creating trust in the blockchain. The rich application scenarios of blockchain are basically based on the fact that blockchain can solve the problem of information asymmetry, and realize the cooperative trust and concerted action among multiple agents
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
as an important breakthrough for independent innovation of core technology, the security risk of blockchain is regarded as a major weakness restricting the healthy development of the instry, and frequent security incidents ring an alarm for the instry. To embrace the blockchain, we need to accelerate the exploration and establishment of a security system suitable for the blockchain technical mechanism
Smart earth NAT is decentralized, and smart earth NAT belongs to real blockchain
the smart earth is divided into three elements, namely "3I": IOT, interconnection and intellectualization, which refers to fully applying the new generation of it and Internet technology to all walks of life, and embedding and equipping sensors into hospitals, power grids, railways, bridges, tunnels, highways, construction, water supply systems, dams and oil and gas pipelines all over the world
the smart earth forms the Internet of things through the Internet; The Internet plus the Internet of things is the world's most intelligent and intelligent world. It is a shared database, and the data or information stored in it is the core feature of blockchain
