What are the application scenarios for blockchain?

Ten categories of industry application scenarios for blockchain are listed on Oracle's website

Including finance, production, education, media, entertainment, government, retail commerce, health, healthcare, supply chain, insurance, and public **** business. Isn't that grand? But what I want to say is that these application scenarios can only hide in the corner first and shiver in front of the real high-powered blockchain applications.

The real high-powered application scenarios of blockchain now are Ponzi applications, commonly known as "Ponzi schemes". It's a smart-contract Moneyball, a blockchain game with rolling deposits and withdrawals, an ICO for trading purposes, and a global pension platform.

The Ponzi scheme is one of the oldest application scenarios of our human race, and after the emergence of the Internet, the Ponzi scheme has been upgraded with an "Internet+", i.e., "Internet+Ponzi Scheme". The Internet empowers Ponzi schemes, so similar to the Qianbao tens of billions of level of events, in the Internet era before, there are few such large-scale Ponzi schemes, through the Internet empowered by the cell phone APP deposit and withdrawal of gold, and finally rolling a few years, to reach a tens of billions of level of scale.

The Internet has realized the breaking of geographical restrictions, physical restrictions, restrictions on the flow of funds, and restrictions on dissemination. As long as there is a cell phone can play money treasure APP, everyone participates, everyone into the gold, everyone out of the gold, involved in the human data said to reach the level of millions of levels, in contrast, also stayed offline to pull the head of the pyramid scheme (Ponzi scheme 1.0), every day to meet the brainwashing can not be stopped, the use of violence and illegal means, it is simply weak. With the rise of blockchain technology, the use of "blockchain +" empowered Ponzi scheme, can not be used as a tiger with wings to describe it, it is simply like a chicken into a tiger. As with the Internet, the "blockchain +" technology to enhance the application of the scene is real, Ponzi scheme in the "Internet +" the second generation of the basis for further upgrading, because there are significant scene enhancement and improvement of breakthroughs into the Ponzi scheme 3.0, which is characterized mainly in the The following aspects are reflected:

1, decentralization, no head. The smart contract of the blockchain runs automatically without human intervention and cannot be interrupted by humans. The code rules are written to death and cannot be tampered with. In terms of scenario improvement, it solves the biggest pain point of Ponzi schemes over the past thousands of years, that is, the problem of the head running away. Because the head is the program, is the code, the blockchain program can do permanent existence, no one can delete it. I think this is the biggest breakthrough. This virtual head is always there, can not run away, will not run, will not change, the rules will always be the same, adhere to the Ponzi route for a hundred years, a thousand years, ten thousand years. There may be people who say that smart contracts can be iterated, and can also be manipulated to leave a back door. That's right, but it can be done without iteration, and even if it is iterated, it is transparent and visible, and if a backdoor is left in, it is also obvious at a glance. This is the characteristic of the blockchain smart contract, you cheat on it, it is equal to taking out a cheat sheet under the eyes of the teacher, such a smart contract, no one participates when it is online. So after technical review, verification, no backdoor, fair rules, irrevocable smart contracts, can be realized using blockchain technology. Such reliability, once verified and passed, is permanent. This is the determinism of the smart contract, a program, a character of code are unchanged, run a million times a trillion times, the result is consistent determinism.

2, process transparency. The number of deposits, address account, amount, time; the number of withdrawals, address account, amount, time; all visible. Blockchain has a public **** ledger function, everyone in the world can view, everyone view the ledger data is completely consistent. Why is Moneyball bursting? Because we can't see his background account, how much money goes in every day, how much money comes out, and the specific details of each one. So that before the deposit can see the assessment of the ability to pay, and the results of this assessment is also absolute certainty, that is, will not change after you deposit money.

3. Complete anonymity. If you've heard of any zero-knowledge proof technology. This part can be skipped. Simply put, before we are inside the mathematical knowledge base of some things, many of the invention is no application scenarios, and then was found that this knowledge is used to do anonymization is very good to use. The cryptography technology inside the blockchain is able to realize identity concealment very well. As we all know, knowledge in the technical structure can not realize the real meaning of anonymity, blockchain can.

4. The rules are open and fair to all. Deposit a dollar, rebate out of ten dollars, everyone is this rule, permanent. You deposit a dollar, first go to the person in front of you out of the gold, and then the person behind you to deposit, and then give you out of the gold. Fair, right? It's something I've reflected on many times, and I think it's still fair.

5, sustainable iteration. Low-level Ponzi scheme, the head, product designers, benefit distributors, benefit recipients are often four in one, and blockchain Ponzi scheme, can be completely logical separation of the four roles. Enabling perpetual iteration. Through social-based collaboration, these projects can iterate forever. There are now 400 senior engineers developing around Bitcoin who are still updating the code, and these people can know no one and iterate as long as the application has value. What centralized project can do that? Even a BAT-level company can't hire this many professionals scattered around the world. This social iteration approach is not affected by changes in a specific person or a specific organization.

"Blockchain" empowered Ponzi scheme, the use of blockchain technology varies in scope, because the technology in this field is still being updated, like smart contracts this piece of the application is only in the past two years more. The earliest blockchain application is Bitcoin, some people think that Bitcoin itself has the characteristics of a Ponzi scheme, in 2013, I wrote a reply to implicitly pointed out that this new type of Ponzi scheme will kill a lot of people, because of the characteristics of no head, open books, will not run, and the rules of the open and fair. Later, I also realized that many people around me have a much higher preference for Ponzi schemes than for blockchain technology. As soon as I heard that Bitcoin is not a Ponzi scheme, before I started to talk a little bit about the technology of the blockchain, usually silently walked away, on the contrary, you tell him that it is a Ponzi scheme, and then they will then ask, where to buy? Of course, there's a lot of debate about whether or not Bitcoin counts as a Ponzi scheme, because the practical application scenarios for Bitcoin are expanding all the time.

While inside the ICO boom, there are a lot of air coins, which are Ponzi schemes as in fake, there is no application scenario, these air coins, the people who buy them probably know that it is a Ponzi scheme, but look at the packaging is good, so they buy it. There are estimated to be hundreds or thousands of such air coins. The cases involved are spread all over the world and amount to more than tens of billions of dollars. These ICOs use smart contracts for pledging and distribution and then circulate themselves to the secondary market. In this case, there is no guarantee of withdrawal, and some people lose their money. Many people blockchain professionals, have been trying to draw a line with these applications, because these air coins, although they use part of the technology of the blockchain, but behind it is still a centralized organization or individual, the network nodes are very few, the user deposits are directly aggregated to a certain organization or individual (and therefore will be rolled away), but there is no doubt that the air coins are still the use of the blockchain for depositing and distributing chips, which solves some of the runaway problem, boosting the scope and spread of the Ponzi scheme. This is what is objectively happening.

Beginning this year, as technology advances, more decentralized Ponzi schemes using smart contracts are beginning to surface. Deposit and issue chips are locked using smart contracts to complete a complete closed loop of deposit, pledge and withdrawal. It can already be a very pure blockchain application, and there are some blockchain games that can already be admitted graciously, publicly claiming that they are a Ponzi game after issuance, and he said, "Look, the rules are transparent, the code is visible, the deposit contract is locked, it won't run out of the way, there is no human intervention, and it will be automatically withdrawn from the fund. Early play early earnings. This is a very critical step in the breakthrough, publicly recognize themselves as a Ponzi scheme, this play is the previous Ponzi scheme 1.0 and 2.0 can not do (not dare to publicly recognize themselves as a Ponzi scheme). Awesome. What a simple and crude way to play.

This solves a major obstacle in the promotion process of previous Ponzi schemes, which used to rely on brainwashing to pull heads, and now rely on the code to speak. You see, "This program will not run away by itself, there is no backdoor in it, right? The head has disappeared, right? Satoshi Nakamoto's capture doesn't affect the program's continued execution, right?" So the first batch of blockchain Ponzi scheme hooked is the code farmers who can read the code, and then these code farmers come forward to say, after technical verification, it is really such an effect, to drive other people who do not read the code to join.

Blockchain in addition to the realization of entertainment, gambling, fraud nature of the Ponzi scheme application scenarios, in relation to the national economy and people's livelihood, the public **** cause of the nature of the Ponzi scheme application scenarios also have the opportunity to make a splash, and even greatly enhance the people's sense of access, a sense of well-being, as well as the actual improvement of people's lives. For example, the blockchain-based national or global public **** pension platform application, this kind of platform because based on the blockchain, can solve several major drawbacks of the pension:

1, the problem of misappropriation of funds. The books are open, the funds are locked non-centrally, and no one can unlock them, except for the recipients who meet the rules to get out of the money. There is no possibility of misappropriation.

2. Inflation problem. The current pension system every year according to a series of complex algorithms such as inflation, adjust the coefficients, after the adjustment, the recipients are often dissatisfied, because the total amount went up, but the purchasing power decreased. The use of virtual currency can not be increased, the characteristics of the rate of inflation can be restrained, to ensure that the receipt of real money.

3. The problem of unpredictability. It is difficult to predict the pension situation after 30 years, through smart contracts can be realized in advance prediction. Stimulate the motivation to pay.

4, policy loopholes and fairness. Any pension policy oriented to the diversity of groups, there will be unfair situations inside, anyone thinking of paying less and getting more, late payment and early withdrawal. The transparency of the blockchain is fine-tuned to each account, rather than a set of generalized policies to plug the loopholes in the implementation process. Everyone is the same, contribute more and withdraw sooner. It can even be inherited and never lost.

Doing so greatly reduces the burden and cost of managing pensions for the state, and what the existing pension system can do, it can still do after using blockchain technology, such as state subsidies, playing money into the contract on the line, and when you play it in, it's locked in, and it won't be fake, such as mandatory contributions, and every record is also real and traceable. In short, the existing system and rules can all be on the chain, without affecting the existing effect on the basis of improving the efficiency and output level, to ensure fairness, and because of the reduction of the cost of the huge management system, each person can receive the absolute number of may be able to rise by a large margin, which plays a real improvement in people's lives, or in other words, there is a sense of access, sense of well-being enhancement. In the matter of pensions, the main body of our trust from a single national government, to the national government + blockchain, more than 50% of the process into a fixed software program, we are not more trusting in this way? If a 100% on-chain pension system is realized, then it could even break the country-wide limitations, by an honest piece of code that doesn't cheat and can't be tampered with, with automatic deposits and withdrawals, and trusting in it is like trusting in a dead person, with no mistakes.

The design of the next generation to support the current generation is a great invention of our human evolution, accelerating the speed of social development, so that on the surface it looks as if the last generation of the earth will be at a greater disadvantage, but it won't be, because the last generation of the earth doesn't necessarily know that it is the last generation (it may know it in the last few seconds, but what the hell), and what's more, with the earth gone, the last generation still need to contribute to retirement? Apparently, no.

Ponzi scheme, the biggest drawback is to run away in the middle of the road, the funds broke, blockchain in solving this problem, there is a clear technical solution, but also can be proved, also able to be disproved, so the technology is scientific. With the drawbacks eliminated and the benefits gradually emerging, the Ponzi scheme will make even more progress in the future.

I would also like to ask a question, in the history of mankind, is there anything that was originally negative, or useless, and then with the development of technology, the drawbacks were eliminated or circumvented, and the role was discovered, and then became more and more useful and important?
