Blockchain of College Students' innovation project

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

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

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

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

With all walks of life have begun to enter the blockchain instry, blockchain has undoubtedly become the world's largest wind in 2018. Since 2014, more than a dozen top universities in Europe and America, including MIT, Stanford University and Princeton University, have successively opened blockchain courses

now, it is no longer limited to the teaching of blockchain technology, and some people are ready to challenge the traditional ecation mode with blockchain technology. According to the times of higher ecation, a group of scholars from Oxford University announced that they would establish the world's first blockchain University, Woolf University

{rrrrrrr}

Course Platform demo according to the official website of Woolf University

actively promote the block chain credit certification

"hope the degree certificate will be widely recognized in the future"

however, there are no doubt many problems to be solved when applying an emerging technology to a new concept. Professor Michael sharens, a professor at the Open University of the UK, said that although the founding of Woolf university is a subversive force in the field of ecation, how to ensure high standards of teaching is a big problem. Although blockchain can ensure the teaching interaction between teachers and students, it can not guarantee the quality of teaching

in this regard, Dr. blocky told the media that the key to the quality of ecation is not whether there is a physical campus, but the ability of teachers. Of course, the school will also have relevant teaching quality supervision measures. First of all, only scholars with real doctoral degrees can join the platform as teachers, and they must upload certificates for verification

secondly, the top five colleges of the university will be composed of scholars with doctoral degrees from world-class universities. After the establishment of five high-quality colleges, Woolf will be open to other scholars one after another

in addition, a ranking system was established among colleges according to the number of teaching and the average score of students. Finally, the university will set up a review system for academic fraud and cheating, which will be regularly reviewed by the dean of the college

then, in addition to ensuring the quality of teaching, how can the academic records of blockchain obtain formal academic recognition

Dr. brocky said that blockchain can help the credit certification process, because the information records it provides are highly accurate and completely reliable. The European Commission has recently published a report on blockchain in ecation, but it will take some time to complete this process

before obtaining official permission, blockchain records will be temporarily used as a part of the application process. For the degree certification of early-stage students, the university will cooperate with existing universities and still use the traditional way to certify credits. In addition, at the initial stage of its establishment, the university will invite ecational institutions such as Oxford college to join the platform and make full use of their existing degree certification mechanism. At the same time, the University of Virginia Woolf has begun to actively seek ecation certification in the European Union and the United States, hoping that in the next 10 years, the degree certificate of Virginia Woolf University will be widely recognized

Dr. blocky said that Woolf university is the future ecation model, which combines online and offline ecation, and connects the world's outstanding students and teachers by building a global talent network“ I hope this model can improve the overall quality of ecation and provide a new way for students to acquire knowledge and achieve success, no matter where they are

Blockchain is the general trend of the tuyere project, but when choosing blockchain projects, we must shine our eyes and find a team with technology, application and real down-to-earth work. Otherwise, it may come to nothing, because since it is a trend, naturally there are a lot of speculation and fraud projects

here, we mainly introce utispace, the first blockchain distributed storage project with perfect technology and real application in the world
