President of blockchain
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

related extension: blockchain financial application:
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
on June 1, 2020, Xinhua news agency was authorized to broadcast the "overall plan for the construction of Hainan free trade port" issued by the CPC Central Committee and the State Council, which will "actively participate in the formulation of international rules for cross-border data flow, and establish standards and rules for data rights confirmation, data trading, data security and blockchain finance" as one of the key tasks of Hainan free trade port before 2035

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

Ten instry application scenarios of blockchain are listed on Oracle's website, including finance, proction, ecation, media, entertainment, government, retail business, health, medical care, supply chain, insurance and public utilities. Is it very tall? But what I want to say is that these application scenarios, in front of real high-energy blockchain applications, can only hide in the corner and shiver
now the real high-energy application scenario of blockchain is Ponzi application, commonly known as "Ponzi scheme". It is a smart contract type Qianbao, a blockchain game for rolling in and out of money, an ICO for trading, and a global pension platform
Ponzi scheme is one of the oldest application scenarios of our human beings. After Internet plus, the Ponzi scheme has upgraded the Internet + "Internet plus Ponzi scheme". The Internet enabled the Ponzi scheme, so there was an event similar to the 10 billion level of Qianbao. Before the Internet era, there were few Ponzi schemes on such a large scale. They were enabled through the Internet, and paid through mobile app. Finally, they rolled for several years and reached the 10 billion level
the Internet has broken the geographical restrictions, physical restrictions, capital flow restrictions and communication restrictions. As long as you have a mobile phone, you can play Qianbao app. Everyone participates in it, everyone gets into the money, and everyone gives out the money. According to the data of the people involved, it has reached the level of one million. Relatively speaking, the online pyramid scheme (Ponzi scheme 1.0), which still stays on the top of the list, has meetings every day, can't stop brainwashing, and uses violence and illegal means. It's simple and weak. With the rise of blockchain technology, the Ponzi scheme enabled by "blockchain +" can no longer be described as adding wings like a tiger. It is like a chicken changing into a tiger. Like the Internet, the "block chaining +" technology is a solid application to enhance the application scenario. Ponzi's fraud is further upgraded in the two generation of the Internet plus, because of the major improvement and improvement of the scene, turning into Ponzi scheme 3, whose characteristics are mainly in the following aspects:
1, centralization and no summit. The smart contract of blockchain runs automatically, and it does not need human intervention, nor can it be interrupted by human. Code rules are dead and cannot be tampered with. In terms of scene improvement, it solves the biggest pain point of Ponzi scheme for thousands of years, that is, the problem of head running away. Because the head is a program and code, the program of blockchain can exist forever, and no one can delete it. I think this is the biggest breakthrough. This virtual leader is always there. He can't run away, he can't run, he can't change. The rules will never change. He will stick to the Ponzi line for 100 years, 1000 years and 10000 years. It may be said that smart contracts can be iterated, and they can also be manipulated to leave a back door. Yes, but it can be done without iteration. Even if iteration is transparent and visible, it can be seen at a glance with a back door. This is the characteristic of the blockchain smart contract. If you cheat on it, you will get out a under the teacher's eyes. No one will participate in such a smart contract when it is online. Therefore, after technical review and verification, there is no backdoor, fair rules and irreversible smart contract, which can be realized by using blockchain technology. Such reliability, once verified, will never change. This is the certainty of the smart contract. A program or a character's code will not change. It will run one million times and one trillion times, and the result will be consistent and certain
2. The process was transparent. The number, address, account number, amount and time of deposit; Number, address, account number, amount and time of payment; All visible. Blockchain has a public ledger function, which can be viewed by everyone in the world, and the ledger data viewed by everyone is completely consistent. Why does Qianbao burst? Because we can't see his background account, how much money he goes in and how much money he comes out every day, and the details of each transaction. In this way, you can see the assessment of cashing ability before you pay in, and the assessment result is absolutely certain, that is, it will not change after you pay in
3. Complete anonymization. If you've ever heard of zero proof of knowledge. This part can be skipped. In short, some of the things we used to have in the mathematical knowledge base did not have application scenarios after many inventions. Later, it was found that it was easy to use these knowledge for anonymization. The cryptography technology in the blockchain can achieve identity hiding. As we all know, Zhihu can't achieve anonymity in a real sense in terms of technical structure, and blockchain can
The rules are open and fair to all. One yuan in gold, ten yuan in rebate. Everyone is the same rule. It will never change. If you pay one yuan, go to the front and pay for it, then the back will pay for it, and then pay for it. Fair, right? I have reflected on this many times, and I think it is fair5. Sustainable iteration. In the low-level Ponzi scheme, the leader, proct designer, benefit distributor and benefit receiver are often four in one, while the blockchain Ponzi scheme can completely logically separate the four roles. Achieve sustainable iteration. Through collaboration based on socialization, these projects can be iterated on forever. There are now 400 senior engineers who are developing around bitcoin and constantly updating the code. These people can not know anyone. As long as the application is valuable, they can continue to iterate. Which centralized project can be achieved? Even bat level companies can't employ so many professionals scattered around the world. This kind of social iteration is not affected by the changes of a specific person or organization
"blockchain" enabled Ponzi scheme uses different range of blockchain technology, because the technology in this field is still constantly updated, and the application of smart contract has only increased in the past two years. The earliest application of blockchain is bitcoin. Some people think that bitcoin itself has the characteristics of Ponzi scheme. In 2013, I wrote a reply and implicitly pointed out that this new type of Ponzi scheme will have great lethality, because it has the characteristics of no head, open account book, no running away, open and fair rules. Later, I also found that many people around me like Ponzi scheme much more than blockchain technology. As soon as I hear that bitcoin is not a Ponzi scheme, before I start talking about blockchain technology, I usually walk away in silence. On the contrary, you tell him it's a Ponzi scheme, and then they will ask, where can I buy it? Of course, there is a lot of controversy about whether bitcoin is a Ponzi scheme, because the practical application scenarios of bitcoin have been expanding
in the ICO boom, there are a lot of air coins, such as the bogus Ponzi scheme, which has no application scenarios. The buyers probably know that these air coins are Ponzi schemes, but they buy them because the packaging is good. It is estimated that there are hundreds or thousands of such air coins. The scope of the case is all over the world, and the amount involved is more than 10 billion. These ICOS use smart contracts for subscription and distribution, and then circulate in the secondary market by themselves. In this case, there is no guarantee that the money will be paid out, and some people will lose all their money. Many people, blockchain professionals, have always wanted to draw a clear line with these applications, because although these air coins use part of the blockchain technology, they are still a centralized organization or indivial behind them. There are few network nodes, and users directly converge to a certain organization or indivial when they are paid (so they will be swept away), but there is no doubt that, Air money still uses blockchain to make money and raise funds, which solves part of the problem of running away and improves the scope and communication ability of Ponzi scheme. This is an objective situation
and from this year, with the development of technology, the Ponzi scheme, which uses smart contracts to achieve more decentralization, began to surface. Smart contract locking is used for fund in and fund out to complete a complete closed loop of fund in, fund subscription and fund out. It can already be a very pure blockchain application. Some blockchain games can freely admit that they are a Ponzi game after their release. He said: you see, the rules are transparent, the code is visible, the gold entry contract is locked, they can't run away, no one intervenes, and the gold is automatically paid. Early play, early gain. This is a key breakthrough. It's a way to publicly admit that you are a Ponzi scheme, which can't be done by Ponzi scheme 1.0 and Ponzi scheme 2.0 before. Great. It's simple and rough
this solves the major obstacles in the promotion process of Ponzi scheme, which used to rely on brainwashing, but now it depends on code. You see, "this program doesn't run on its own. There's no back door in it, right? Is the leader gone? The capture of Nakamoto does not affect the continued implementation of the program, does it Therefore, the first batch of blockchain Ponzi scams are hooked by code farmers who can understand the code, and then these code farmers stand up again and say that after technical verification, it is really such an effect, driving other people who do not read the code to join
in addition to realizing the Ponzi scheme application scenarios of entertainment, gambling and fraud, blockchain also has the opportunity to make a big show in the Ponzi scheme application scenarios involving the national economy and the people's livelihood and public utilities, which can even greatly enhance people's sense of gain and happiness, and actually improve people's life. For example, the application of national or global public pension platform based on blockchain can solve several major drawbacks of pension: fund misappropriation. The account book is open, the funds are not centralized and locked, and no one can unlock it, except the recipients who meet the rules can pay out the money. There is no possibility of misappropriation
2. Inflation. The current pension system adjusts the coefficient every year according to a series of complex algorithms such as inflation. After adjustment, the recipients are often dissatisfied because the total amount has increased, but the purchasing power has decreased. Using the feature that virtual currency can't be issued, we can control the inflation rate and ensure that we get real money3. Unpredictable problems. It is very difficult for us to predict the pension payment after 30 years, and we can predict it in advance through smart contract. Stimulate the enthusiasm of paying
4. Policy loopholes and fairness. There will be unfairness in the diversification of groups that any pension policy faces. Everyone wants to pay less and get more, pay later and raise earlier. The transparency of blockchain is refined to each account, rather than a set of general policies to plug the loopholes in the implementation process. Everyone is the same, pay more, pay earlier, pay earlier. It can even be inherited and never lostthis has greatly reced the burden and cost of the state's pension management. What the existing pension system can do, after using the blockchain technology, can still be done, such as the state subsidies, just pay money into the contract, lock it in, there will be no fake, such as compulsory payment, and every record is real and traceable. In a word, all the existing systems and rules can be linked to the chain. On the basis of not affecting the existing effect, the efficiency and output level are improved, and fairness is guaranteed. Moreover, because the cost of the huge management system is reced, the absolute number that everyone can get may be increased by a large part. This has played a real effect on improving people's lives, and also has a positive effect
Although the current blockchain technology is still in the initial stage, the advantages of this technology have begun to be reflected. In many fields, blockchain can proce great value, and I believe there will be more landing application scenarios in the future,
blockchain + cross border payment
at present, the mainstream way of cross-border remittance is wire transfer, and its cycle is generally as long as three to five working days. In addition to certain handling charges, intermediary banks will charge certain handling charges, Swift (Global Interbank Financial Telecommunication Association) will also charge a higher fee for the message exchange of its system. In China, a single fee of 150 yuan will be charged for cross-border remittance through the Bank of China
and the use of blockchain technology allows the remitter and the payee to pay and settle directly, eliminating all intermediate costs, so that cross-border payment and settlement can be completed point-to-point quickly. While improving the speed of settlement, it can also achieve all-weather payment, real-time arrival, simple embodiment and no hidden cost
Ma Yun's confidential project was restarted 19 years ago, which is a new international trade and financial services platform trust . The name of trustle comes from "trust made simple". It is a confidential project to solve the problem of International Trust proposed by Ma Yun at the initial stage of his business. After 19 years, the design was completed by relying on new technology
On the afternoon of September 25, when Jiang Guofei, vice president of ant group and President of Intelligent Technology Group, released the trustle platform at the Bund conference, he revealed that "trustle platform uses blockchain technology to restart a confidential project within us 19 years ago, and solves the trust problem between buyers and sellers in international trade.", like Alipay's original intention to launch secured transactions, Trusple is also designed to solve the problem of transaction trust. The difference is that because of the outstanding characteristics of block chain technology in solving complex process trust, Trusple is better able to meet the needs of international trade trust. Jiang Guofei said
extended information:
the landlady of Hubei Xianning glass factory attended the global financial conference
Yuan Jing from Xianning, Hubei Province, took the stage to speak as the first user of the trustle platform. Just a few days before the Bund convention, she sent a single crystal glass proct to Mexico through trustle
Yuan Jing's glass factory is located in Luguo village, henggouqiao Town, Xianning City, Hubei Province, where the factory helps poor households get rid of poverty and increase their income. As a result of long-term foreign trade business, Yuan Jing has set up an office in Yiwu, and all the glass procts proced by Xianning factory are sold abroad
in September this year, as the first user of the trustle platform, she sold the company's main crystal jewelry to Mexico, and received the payment the next day. In the past, trading alone often took a week
in the past international trade process, the procts proced by Yuan Jing factory are basically 30% down payment by the customer, 40% after seeing the bill of lading, and the remaining 30% is completely relying on the credit line to the customer, and the customer agreed to pay the money in 1-2 months
if the customer's goods are not sold well or for other uncontrollable reasons, Yuan Jing will face the risk of not being able to recover the full payment. Due to the low profit of the proct itself, once there is the risk of default, it will be in vain in recent years
"we have always been used to this way, but we didn't expect that technology could bring new models." Yuan Jing said, "at that time, Ali came to me and asked me if I wanted to have a try. I didn't know what blockchain was, but I believed in Alibaba and thought that if I had a try, I would have a try. When you think about the international trade situation this year, the emergence of trustle is definitely a surprise. "
"through trustle, as long as the agreement is signed with the bank, the customer only needs a few steps." Yuan Jing said that with the blockchain technology, she no longer worries that international buyers will not pay the balance
in the bottleneck period of world economic development, Xiaomei consumes the world's wool with its biggest scam
don't participate, don't listen, set up the national force to prohibit it, don't participate in the construction of any digital asset transactions, and don't be the eternal sinner of the motherland
blockchain technology is a waste of resources, not in line with the development of intensive economy! Simple things are complicated, and small resource consumption becomes multi resource consumption
data storage doesn't need money, and servers don't need money. And who can guarantee that the server data will not be lost. Natural and man-made disasters, natural strain. Does it make sense to play the virtual game of wasting the resources of the real economy? After all, there are so many people who don't have enough to eat!!!
a day ago, Sheng Songcheng, counselor of the people's Bank of China and executive vice president of China Europe Lujiazui Institute of international finance, also said that the future of blockchain is to serve the real economy“ If blockchain and virtual currency are combined, and blockchain is mainly focused on virtual currency, I don't think blockchain will have a future. " Sheng Songcheng said
Li Lihui, head of the blockchain research working group of China mutual Finance Association and former president of Bank of China, believes that the future development direction of blockchain is large-scale application. In his view, how to achieve large-scale application depends on four factors: efficiency, cost, reliability and safety, and system
Zhu Min, former vice president of Bank of China, central bank and IMF, and now president of National Institute of finance of Tsinghua University, said at the Boao Forum: "when talking about blockchain, we should first separate blockchain from bitcoin, which is not a concept. As a technology, blockchain is revolutionary and unlimited in the future. Blockchain technology will have great application prospects in the future, and the future is very good. "
"the combination of blockchain and virtual currency has no future"
as early as 2014, Sheng Songcheng published an article in an authoritative journal, explaining that virtual currency is not currency in essence from the origin and essence of currency
in his view, if virtual currency overflows, monetary policy can not be implemented, and monetary policy is one of the main means of macroeconomic regulation and control in the world
according to him, when virtual currency first came out, the attitude of central banks was not unified“ But up to now, we have basically unified our views, at least we do not recognize it as currency, because it will hinder the implementation of the whole monetary policy. " Sheng Songcheng said< As early as November 20, 2013, Yi Gang, who was also vice president of the people's Bank of China, first talked about bitcoin at a forum. At that time, he said that from the perspective of the central bank, it was impossible to recognize the legitimacy of bitcoin in the near future. However, he also believes that bitcoin trading, as a kind of trading behavior on the Internet, ordinary people have the freedom to participate
at that time, Yi Gang's statement was interpreted as good news by some bitcoin investors. They believed that although the regulatory authorities did not recognize the legitimacy of bitcoin, they did not characterize it as illegal and would not directly interfere in the trading of bitcoin. But unexpectedly, the price of bitcoin fell to 4150 yuan the next day.
Oracle is involved in the field of blockchain, is mainly to expand its own business
Oracle, a database software giant, has officially become a member of the blockchain field. The technology giant officially announced its enterprise blockchain cloud platform at the OpenWorld conference 2017 in San Francisco. With this debut, which is expected to be officially launched sometime next year, Oracle has become the latest entrant to the "blockchain as a service" ecosystem, joining two technology giants, IBM and Microsoft, which are currently attracting enterprise customers to use their own cloud distributed ledger resources. According to Oracle executives' statements and statements, Oracle is trying to use cloud computing technology to expand (simplify) existing cloud procts, mainly for digitization of various businesses
he explained that the data of the blockchain network needs to be saved by all nodes. The increasing adoption of blockchain by Oracle's core customers will actually bring new requirements to the company's traditional data storage solutions. " In traditional computer science, there is only one of a database. For blockchain, all ledgers are distributed, so in fact, everyone has a of the data. This will only expand the demand for data storage. "
