Application of quantum blockchain system in business
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 biggest feature of blockchain technology is decentralization, which will rece a lot of costs for the banking instry
First of all, decentralization means that the trust building mechanism between banking systems no longer needs intermediary, which saves the cost of intermediary Secondly, the development of digital currency will realize the real-time digital transaction of banks. For example, in bill transaction, bank's bill transaction always relies on the third party to realize the transfer of valuable documents. Even for electronic bill transaction, it also needs the information of central bank's ECDs system for mutual authentication. The blockchain technology can realize the point-to-point value transmission, which no longer needs centralized system control. This not only speeds up the bill transmission speed, but also reces the mistakes caused by human factors. The rection of process will naturally rece the demand of the bank for personnel and save the labor cost of the bankfinally, it will also have an impact on clearing and settlement. The bank's clearing and settlement business has always been completed by the central settlement, with low efficiency. Settlement through blockchain technology will greatly improve the efficiency of banks
blockchain technology also plays an important role in the cross-border payment business of banks. Today, with the highly developed global trade, cross-border payment is becoming more and more frequent. Banks often act as third-party services in cross-border trade, such as electronic transfer, asset custody and so on. However, cross-border payment generally takes about two days to get to the account, which is inefficient and reces the utilization rate of funds in transit. In the blockchain technology, both sides of cross-border payment can complete through the point-to-point way, realize all-weather payment and real-time arrival, thus speeding up the speed of clearing and settlement, and improving the efficiency of bank business processing
another feature of blockchain technology is de risking. Banks can establish their own blockchain, which can ensure that the transaction information and transaction records of bank customers are true and effective, and will not be tampered with arbitrarily. Banks can effectively identify customers' information, understand all aspects of customers' situation, identify abnormal transactions of customers, and prevent being cheated by customers, So as to rece the cost of bank supervision
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
The mechanism of mineral refresh in the original God is 72 hours (3 days) refresh. Four people form a team to dig the mine, and rotate every day. They can also dig all the mines of four people at one time, once every 4 days. But they still have to go to the blacksmith's place to make iron every day. Crystal ore is refreshed every 3 days, white iron ore is refreshed every 2 days, and iron ore is refreshed every 1 day
for the mining mechanism, there is no upper limit (or the upper limit is very high) for mining every day after the public beta, but the weapon experience materials obtained by forging in different ways at the blacksmith every day have a common upper limit of 300000 (equivalent to 120 crystal minerals, except weapons), which means that iron ore, white iron ore and crystal ore share the upper limit
extended data:
it is suggested that three people should take turns to dig one person's world's mine a day; Suppose we dig a on Monday; Dig B on Tuesday; Dig C on Wednesday; Thursday dig a; By analogy, there will be mines every day. Similarly, Xiaobian suggests that the resources with a brush of 48 hours should be mined once every three days
in the game of the original God, the more advanced the ore, the longer the refresh time. For example, for low-grade ore such as iron ore, the refresh rule is once a day; Pyrite, yeposhi and perlite are refreshed every two days, while crystal ores are refreshed every three days
Yesterday I played for 12 hours. I would like to say that it's very important what planet you arrived at. It took almost an hour to repair the plane at the beginning of the game. Because I found the required isotope and repaired the spaceship, I knew that there was material to dig next to the spaceship. The radar even instructed me to dig (sweat) in the mining area 3 minutes away It's easy to collect meteorites from space.
2. Plutonium can replenish life support devices, mining beams and drive fuel. It can save a little more
< 3. Dig the place It's a mine with small proction on the planet. If you dig too much at one time, the patrolmen will attack you. So half of the patrolmen will come to scan you. Stop mining immediately
4. As long as you enter the house, the patrolmen who attack you will retreat. So there are rare mines in need. As long as there is a room nearby, dig carefully. If the patrolmen attack, just run into the house Break the door and rush into the house. The patrolman will go. But only the house that can't use weapons looks useful. For example, the launch mole should not hide from the patrolman
5. The point of the launch mole on the planet. A launch mole can spend money to increase the space of a suit. I currently drive to 26 spaces. I don't know if the suit is full of 30 spaces
6. Abandoned spaceships can be found on the planet If it's better than the existing one, you should pay attention to it before changing. You need to transfer the goods. Also, the abandoned spaceship needs to be repaired. Pay attention before changing the spaceship. Otherwise, you can't fly after changing the spaceship (but your original spaceship will be left nearby after changing the ship. You can change it back first)
7< /p>
8. The NPC spaceships in the space station and the trade station can interact. They can buy or sell, or buy each other's airplanes
9. If you find the place you want to go to, how can the distance and time keep increasing and decreasing? The representative place is on the other side of the planet. So flying out of the atmosphere and moving, you can accurately find
