Blockchain 30 times PE
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
The most important reason why blockchain is questioned is that there is no practical application scenario, and ordinary people can't see the possible value. In the eyes of these experts, where are the most likely application scenarios of blockchain
Shuai Chu, the founder of quantum chain, said: at present, the evolution of the whole blockchain technology is still at an early stage, just like the Internet era 20 years ago. At that time, we could not imagine that there would be applications like Uber on the Internet. The development of technology would give you more diversity. The possibility is the future According to the technical characteristics of blockchain, Zeng Ming, Dean of Hupan University, gave several possible answers:1. The most important advantage of blockchain is transparent, unchangeable and distributed ledger. Some areas have never been covered by the Internet, such as acceptance bills
2. Another big advantage of blockchain is that from the perspective of smart contract, it is possible to form more efficient network collaboration at the point-to-point level. Like crowdfunding
3. In the field of innovation, blockchain will definitely be closely combined with the development of Internet of things, artificial intelligence and other fields, including cloud computing, edge computing and so on
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
1. Decentralization
the core advantage of blockchain technology is that it does not need a traditional centralized organization, and does not rely on the point-to-point transaction, coordination and cooperation of a credit center in the distributed system, so as to avoid the common problems of data security, collaborative efficiency and risk control of centralized organizations
2. High security
in blockchain technology, data is difficult to tamper with. Anyone can access the database that records transactions. In this transparent and open mode, everyone can act as a supervisor. We can see at a glance what changes have taken place in the data, which is more secure than traditional technology
3. More reliable
the blockchain technology is connected by multiple nodes in different places. The nodes in the blockchain interact through the point-to-point communication protocol. Under the condition of ensuring the consistency of the communication protocol, different nodes can be processed by different developers using different programming languages and different versions of the whole node
in short, when a node encounters network problems, hardware failures, software errors or is controlled by hackers, the operation of other participating nodes and systems will not be affected
therefore, blockchain is more reliable than traditional technology
therefore, I firmly believe that the application of blockchain must be the development trend in the future.

Xiaobian brings you a complete collection of adventure and mining hero personal skills to help you have a comprehensive understanding of the advantages and disadvantages of skills. If you are interested, please accept it as soon as possible
Pure: the strongest and most practical skills at present, with King PVP one & quot; Dad;, It is the mainstream from the middle to the later stage. The pure advantage, first of all, is stability, second, pure disregard for defense and evasion, and finally, many copies are pure to pass, which is really IMBA. If we really want to talk about the pure weakness, it is the weakness in the early stage, but this stage is very short and harmless
Critical hit: the pioneers of the web version have summarized that the best lineup in the early stage is to attack critical hit stream first. It's true that in the early stage, when everyone's defense is not high enough, the benefit of critical hit is far greater than that of pure attack. In the middle and later stage, when everyone's defense is high enough, critical hit is more likely to catch chickens
Recovery: there are two kinds of recovery skills (self and opponent). The two kinds can be divided into four kinds (self maximum health value, self current health value, opponent's maximum health value, opponent's current health value). Recovery is different from blood sucking. You can recover blood whether you hit or not. In the two categories, those related to their own health value are suitable for PVP, and those related to their opponents are suitable for PVE (some levels must have this skill). I won't go into details
Blood sucking: blood sucking is very weak, yes, very weak. Among the skills of blood sucking, the only one that can be put on the table is the strategy of the two soldiers and guards. The others are weak. However, Zika has been eliminated in the middle and late period, and everyone's defense is high in the middle and late period, so it can't suck much blood. The specific weakness of blood sucking lies in the following points. First, blood sucking can only be profitable if it is hit. Second, most of the blood sucking cards have low absorption rate, with only two soldier guards as high as 200% (but there is no egg use). Finally, blood sucking is a tragedy if it is hit on high defense, with less damage and less blood sucking
Disabled (weak): pvppve are practical, there is only one disadvantage, not necessarily (except Xiuji)
Seal: at present, there are too few and weak seal cards, so people who use seal are very rare, but this does not mean that the seal is weak. In fact, the seal is very strong. In PVP, who seals the other party first will get a great advantage, but the disadvantage is also very obvious. Seal is not a must, and the early effect is very small, and it can not be printed, so we can only wait and see the seal card coming out later
Copy: the stronger the enemy is, the stronger I am
Percentages: there are two kinds of percentages: the opponent's current level and the upper limit of the opponent's level. Among them, the current level is relatively funny (only Satan is OK). The percentage PVP is very weak, and the PVE is passable. It is not recommended to use this skill
Slash: PvE and PvP are very awkward. If you can't hit a person, you don't say it first, and the damage after hitting a person is often lower than that of general attack. There are only two cards available in this series
Backwater: it's similar to chopping, but it's more embarrassing than chopping. It can be defined as useless
Multiplier: note that this multiplier has nothing to do with critical hit. Even 350% is not critical hit. Very simple skills are generally attached to other skills. They can be regarded as a common attack with high damage. They can be used in the early stage, but they are weak in the middle stage
