Tencent blockchain scene landing application

1. There are many applications that have been implemented in blockchain. Although they can not be adapted to all application scenarios, there are many applications on the market, such as micro three cloud. Their blockchain integral system has many application scenarios such as e-commerce and content payment, and has been certified by many businesses.

2.

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 fair

5. 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 money

3. 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 lost

this 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

3.

In the field of blockchain, Tencent's blockchain is developing relatively fast. As early as 2015, Tencent's blockchain team has begun to pay attention to blockchain technology, and has carried out independent research and development. As of December 31, 2019, the number of Chinese invention patent applications related to Tencent's blockchain has reached 990, ranking first among Chinese application enterprises. After several years of research and development and exploration, Tencent blockchain has achieved good results in both the development of underlying technology and the construction of instrial ecology

the history of Tencent blockchain development:

there are no technical problems, just whether to do it or not. "

CAI Yige, the head of Tencent's blockchain, replied when asked what technical problems he encountered. On reflection, he added that technologies that have made breakthroughs in theory, such as secure multiparty computing and zero knowledge proof, have not yet been engineered. This is a problem for the whole instry

for Tencent blockchain, the bigger problem seems to be finding more scenarios“ "Blockchain + supply chain finance" is the scene Tencent vigorously promotes this year

at the end of last year, the supply chain financial service platform Xingbei cloud chain was released, and its underlying blockchain technology is the support provided by Tencent blockchain. In addition, Tencent also invested in uniifnance, which is Tencent's only strategic investment in supply chain finance

in the past nearly a year, how has the scene and Tencent blockchain progressed

today, after the founding meeting of the blockchain policy and law research group and the release of the white paper on blockchain and supply chain finance, odaily planet daily interviewed Cai Yige, general manager of Tencent's blockchain business, and Ji Kun, general manager of lianyirong company

according to the two people, in less than a year of operation, the flow of micro enterprise chain platform on the chain is about tens of billions of transactions, 12 banks are connected, and more than 70 enterprises are involved, involving energy, automobile, manufacturing and other instries. Now the penetration supplier level is about level 1 and level 2, which can rece the interest rate by 2-8 points compared with the traditional bank loans

micro enterprise chain platform is a key case of Tencent in supply chain finance. Tencent mainly provides the underlying technology infrastructure, including the underlying self research alliance chain, real-time clearing and account receiving capabilities; Lianyirong is mainly responsible for integrating resources and promoting the platform

supply chain finance is the head scene of blockchain, but in fact, the real implementation is still very slow, which makes people doubt the real change it brings. The two do not deny that this business is in a very early stage, and it will take some time to promote enterprises to join. However, they both believe that "after joining the blockchain, supply chain finance will actually have a very big change."

what the daily planet wants to know more is that with the addition of the supply chain finance after the blockchain, will enterprises and financial institutions be more willing to join? And can this rece the balance of SME loans and increase the number of enterprises that get loans

"(Supply Chain Finance) the biggest difficulty lies in the participation of financial institutions, because they can provide funds in the market." Ji Kun believes that the addition of blockchain can enhance the willingness of banks to enter the supply chain finance

in his opinion, the traditional banks of the four major banks are quite keen on the layout of blockchain. He said that the decentralization of supply chain finance itself and the authenticity of underlying assets are very difficult to check. Traditional financial institutions are not the mainstream, and there is no way to achieve penetration before. Therefore, banks can only get the data of primary suppliers, but the secondary and tertiary suppliers may need financing most. Now blockchain + supply chain finance has changed the credibility of multi-level data flow, strong credit can not be separated, and the synchronization efficiency of information, so that small, medium and micro enterprises which were difficult to obtain loans from financial institutions in the supply chain in the past can also obtain loans. The bank has always wanted to do the business of secondary and tertiary suppliers, and joined the blockchain to better control its own data

as for promoting enterprise use, Ji Kun said that many enterprises need some time to accept it, but because the block chain of supply chain finance mainly replaces the original role of commercial bills, the circulation of commercial bills itself has some pain points, such as counterfeiting, so they are relatively easy to accept

when the daily planet asked about how to ensure the authenticity of the information on the chain, Cai Yige said that different information can be cross verified, but he also thought that this was a problem indeed, and the use of blockchain could not guarantee the authenticity of the information on the chain. Therefore, the first step of the micro enterprise chain is actually accounts receivable. It is true to use invoices to protect the underlying assets. With the electronic business system of small and medium-sized enterprises, it will go deeper in the future

he added that blockchain can also improve the efficiency of information synchronization“ I think it's the control of information. In the case of centralization, even if you have information, you can tamper with it. "

with the focus of Tencent blockchain this year, we naturally want to know the future plan. However, Cai Yige's answer is the same as that at the beginning: "we can't talk about the plan. We will continue to think about the scenarios under which the blockchain can play its value."

about the development of this area:

first, we must choose the right scene, and we must find experts in this instry

Secondly, it should be in line with the nature of technology and have commercial value

Thirdly, it should meet the needs of future development

Fourthly, the architecture should be fully integrated with other technologies to solve the problem

the concept of blockchain should be a new outlet, specifically more use of network search, increase knowledge, network search results - Tencent blockchain development to you

4. Blockchain and digital currency are two independent indivials, and the term blockchain currency does not exist. At present, the mainstream digital currencies include bitcoin, Ethereum, bitcoin, cash, grapefruit, etc. the corresponding subtitle abbreviations are BTC / eth /

5. The application of pre blockchain technology is in an exploratory period, with more conceptual things and less real transactions and projects actually implemented. However, now some instries have begun to try blockchain technology. According to the analysis of jinwowo network technology, within three years, blockchain technology can be deeply integrated with the instry, and blockchain may be implemented in the three fields of sharing economy, supply chain management and digital asset management.

6.

A: the practical application of blockchain technology

I. in financial field

blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields

the application of blockchain technology in the financial instry can save the third-party intermediary link and realize the point-to-point direct docking, so as to greatly rece the cost and quickly complete the transaction payment

Second, the Internet of things and logistics

blockchain can also be naturally combined in the field of Internet of things and logistics. Through blockchain, we can rece logistics costs, trace the proction and delivery process of goods, and improve the efficiency of supply chain management. This field is considered as a promising application direction of blockchain

Third, in the field of public service, blockchain is closely related to people's proction and life in the fields of public management, energy and transportation. However, the centralization of these fields also brings some problems, which can be transformed by blockchain

Fourthly, in the field of digital right, through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works and ensure the authenticity and uniqueness of ownership

In the field of insurance, insurance institutions are responsible for fund collection, investment and claim settlement, and often have higher management and operation costs

Sixth, the data stored on the public welfare field

blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios

7. Tourism: triporg travel is a blockchain tourism service application, which can provide people with air tickets, train tickets and other tourism services.

8. Blockchain is a disruptive technology that will change many instries in the future, just like the Internet many years ago. Blockchain search on the Internet, Tencent's blockchain invoice and Alibaba's rookie logistics are all using blockchain. At present, there are companies specialized in providing this kind of blockchain landing service for enterprises, and the small area is one of the representatives

9. Specifically, a large number of distributed points are used to record transactions instead of central records. In this way, the data can not be changed and trust is generated. Further, mediation is used. Logic comes step by step. Now, there are a lot of online blockchain training, which are the most basic contents. No one raised or answered the problems of distributed storage. Through research, I think the most important point for blockchain to be implemented is whether distributed storage can be realized? This problem is actually a problem, at least for now. Is the capacity of the storage point sufficient? Many training institutions often use Taobao to do the case. Buyers and sellers have data on Taobao. Alipay makes intermediary guarantees to ensure that both parties can trade normally. Blockchain technology allows each distribution point to keep accounts, so the storage capacity of each distribution point is estimated to be less than 1 / 100 million of Taobao. How can it be stored? It is impossible to make every point prepare the same storage as Taobao. From the scale, capital are not allowed, even if it can, it can not, because this rendancy is too large, you can imagine, millions of Taobao storage scale, how a waste of resources. The storage space of home computers is not enough for blockchain data storage. So, how to solve this problem? First of all, we should reach a consensus on the scale of bookkeeping. For example, 10000 is the upper limit. In this way, bookkeeping can not be unlimited. Secondly, storage and sharing. Nowadays, computers in many families are hardly used, and the rich space can be shared. Thirdly, the storage technology has made great progress, and the storage capacity is growing exponentially.
