Why did you mention blockchain all of a sudden
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
Blockchain is on fire! It's so hot that I have no friends! In recent days, it has been swished by various popular science jokes of blockchain, just like crowdfunding, equity and original stocks in the past two years. If you go out and chat with others, you will be embarrassed to chat with others if you don't talk about blockchain. Textbook like explanation: an intelligent peer-to-peer network that uses distributed database to identify, disseminate and record information. It is a distributed database system with different nodes and an open ledger
the concept of "after the rules are settled, everyone will register spontaneously" in wechat organization corresponds to the concept of "decentralization, no single user can control it" in the blockchain. "Registration in wechat group" in wechat group corresponds to the concept of "peer-to-peer network" in blockchain. "As long as the network is connected, we can know the latest progress" in wechat organization Bureau, corresponding to the concept in blockchain, namely "game mechanism"
Abstract: developed countries and technology companies have been ahead in the research and application of blockchain technology. From the perspective of patent application, there may be a gap of about one and a half years between China and the United States in terms of blockchain technology. Based on the above situation, how can China achieve "asymmetric" catch-up? First of all, we should see the situation clearly, seize the opportunity and meet the challenge. Secondly, after understanding the necessity of building the bottom layer of the blockchain for the existing business and future development of the financial instry, a consensus of "China's financial blockchain alliance" was reached among financial enterprises. Finally, we should work together to meet the change
how to understand blockchain
bitcoin: a peer-to-peer e-cash system. In 2009, after the paper was published, bitcoin was born as a virtual currency in the digital world of the Internet. At present, bitcoin's total market value is about US $6.5 billion. Although its market value is constantly changing, it is still the largest virtual currency in the world
another important concept is blockchain. Blockchain is an underlying technology of bitcoin, and bitcoin is only an application of blockchain. As we all know, bitcoin can achieve point-to-point value transmission. In addition to bitcoin blockchain, there are many other blockchains, such as Ethereum blockchain. Therefore, we should distinguish the concepts of bitcoin, bitcoin blockchain, blockchain and blockchain technology
at present, there are several misunderstandings about blockchain. Blockchain can be described in English as "decentralized blockchain", in which decentralized is translated as "decentralized". However, I think that the blockchain has realized the value dissemination without intermediary, that is, the point-to-point value dissemination. This does not mean that after entering the era of blockchain, there is no need for the center, but it should develop from a single centralization to the parallel between centers. Then, the existing center is likely to become a sub center or weak center. At present, all banks have their own data centers. If the financial blockchain alliance is established in the future, they can become the nodes in the blockchain alliance, so the blockchain does not need a center<
blockchain does not need credit
we often see some articles that think that blockchain is to "de credit". In fact, blockchain is to build trust through consensus algorithm and ensure the correctness of transactions through consensus among nodes. Build trust with low cost through mathematics and algorithm, rather than "de credit". However, the digital asset transaction between people does not need two people to know each other, or trust each other, and does not need a third-party credit institution. It only needs everyone to trust the trusted network of blockchain
why is it credible? Because it is a distributed database, there is a set of consensus based mechanism: a set of encryption algorithm, making it tamperable. On the one hand, the public key makes the information transparent and traceable; On the other hand, private key can protect privacy
blockchain is not a mature technology, nor is it omnipotent. At present, blockchain technology is still in the early stage of development. At the beginning of this year, we sent a delegation to study in the blockchain Research Laboratory of Barclays in South Africa. At the seminar, experts on the African blockchain of Barclays believed that it would take at least five to ten years for the blockchain technology to become a truly mature technology. At present, blockchain has the disadvantages of relatively slow computing speed and small storage space, and not all data processing needs to use blockchain
the research and application of blockchain in foreign countries
we find that the old financial developed countries have been ahead in the research of blockchain technology. The British government believes that it is very important for the government to participate in the legislation of digital currency and blockchain network, and encourages in-depth research on blockchain technology. The UK government is actively evaluating the potential of blockchain technology and considering using it to rece financial fraud and cost. In addition, the UK government plans to develop applications that can be used between the government and public institutions
in February this year, the European Commission put crypto digital currency at the top of the fast development target area, which promoted the policy research of various institutions on digital currency. Technology companies are also ahead in the research of blockchain technology
IBM launched the "open ledger project" to develop enterprise level blockchain software structure, promote the commercial use of blockchain technology, and support the docking of external data through the bluemix and API infrastructure of IBM cloud computing platform. IBM still has a lot of practice in blockchain technology. Recently, it and a South Korean company have made creative experiments using blockchain technology and Internet of things, and achieved some results
Microsoft uses Azure Platform to provide users with "blockchain as a service", which enables R3 and its bank members to speed up the process of experiment and learning, and accelerate the development, testing and deployment of distributed accounts
Intel also released sawtoothlake, an efficient molar platform for building, deploying and running distributed ledger; At the same time, Intel also studies to create a trusted execution environment for hardware chips of blockchain applications, providing higher security and privacy< At the same time, Wall Street is taking positive actions. Although it was established relatively late, the core function of R3 is to formulate instry standards for the development of banking blockchain technology, explore practical uses, and establish banking blockchain alliance
from what we know, in addition to these two new companies catering to the arrival of digital finance era, large financial institutions are studying blockchain technology and building their own blockchain concept and technical team
at present, there are practical application cases of blockchain technology
in Canada, blockchain start-up blockchain Tech Ltd has been listed on the growth enterprise market of Toronto Stock Exchange; The Estonian government will launch the government's blockchain healthcare record
domestic attention and Research on blockchain technology
blockchain is an optional technology. Prior to that, the people's Bank of China also held a seminar on digital currency. In addition to the central bank, Zhejiang Province, Beijing and other relevant departments also expressed their support for blockchain application research last year
from the perspective of enterprises, Bubi blockchain has been applied to equity, supply chain, points and other fields, and is concting experiments and application tests with exchanges and banks. Bubi blockchain focuses on the innovation of blockchain technology and procts, has a number of core technologies, and has developed its own blockchain service platform. Moreover, many blockchain innovation and entrepreneurship enterprises continue to emerge
in addition, a number of instry alliances are being established. In terms of financial institutions, the cases of blockchain application by large banks and financial institutions in China still need to be solved
by the end of 2015, Bank of America had obtained 15 patents on blockchain. There may be a gap of about a year and a half between China and the United States in blockchain technology
the application of blockchain finance is entering a new stage in an all-round way, various applications will be more and more in-depth, and the relevant changes will be more and more attention, and a great new trend will be formed.
I believe most people have heard of cryptocurrency bitcoin. Blockchain is the underlying technology of bitcoin. It is a chained data structure composed of data blocks connected in sequence according to the time sequence, and it is a distributed account book that can not be tampered with and forged by cryptography
there are a lot of blockchain landing applications, and those who are interested can have a look. Cryptography focuses on blockchain messages.
in this & quot; Money is not everything, but without money, you can't do anything; In today's society, we rack our brains every day to think about how to make money, but how much can we make enough to spend? Let's take the results of a survey of 500 people based on the price in 2016 to find out how much money we need to earn if we want to live a life with quality
I'm not Gao Fu Shuai or Bai Fu Mei. So it can be seen from the figure that a person's life will cost nearly 3.8 million. If you work for 35 years in your life, your annual income will be about 110000. Other consumption includes clothing, hobbies, interpersonal communication and tourism
doctor: if people eat grains, they will inevitably get sick, so they still need to buy a medical insurance
food: food is the most important thing for the people, and the eaters certainly can't imagine that a person can eat more than 600000 yuan in his lifetime...
Housing: This is a big expense, and there must be a house. Congratulations to those who already have a house, you can subtract nearly 1.7 million yuan from the above goal
OK: 596000. If you buy a car at the age of 25 and drive to the age of 55 without changing the car, except for 30 years' insurance, maintenance and fuel, it is recommended that you buy a car with less than 200000 yuan
Learning: personally, I think the most important thing is this. This money is not much compared with other projects, but it is an investment in self appreciation, which can make you use this lever to raise 3.8 million yuan of income. Students who are still studying, study hard, and don't waste their good youth. There are still many challenges in the future
finally, Tucao, according to the above picture, if you are in the two or three tier city, you can really make complaints about 5 million lottery tickets.
