⑴ What are the application scenarios of blockchain
On Oracle’s website, ten types of industry application scenarios of blockchain are listed
Including finance, production, education, media, entertainment, government, retail commerce, health, medical care, supply chain, insurance, and public utilities. Isn’t it very noble? But what I want to say is these application scenarios. In the face of truly high-powered blockchain applications, these application scenarios can only hide in the corner and tremble.
Nowadays, the truly high-powered application scenario of blockchain is Ponzi application, commonly known as "Ponzi scheme". It is a smart contract-type Qianbao, a blockchain game with rolling deposits and withdrawals, an ICO for transaction purposes, and a global pension platform.
Ponzi scheme is one of the oldest application scenarios of our mankind. After the emergence of the Internet, Ponzi scheme has been upgraded to "Internet +", that is, "Internet + Ponzi scheme". The Internet empowers Ponzi schemes, so events like Qianbao's tens of billions occurred. Before the Internet era, there were few Ponzi schemes of this scale. Empowered by the Internet, deposits and withdrawals were made through mobile APPs, and finally rolled In a few years, it has reached a scale of tens of billions.
The Internet has broken down geographical restrictions, physical restrictions, capital flow restrictions, and communication restrictions. As long as you have a mobile phone, you can play the Qianbao APP. Everyone participates, everyone deposits money, and everyone withdraws money. The number of people involved in the case is said to be in the millions. Relatively speaking, it is still an online pyramid scheme (Ponzi scheme 1.0), every day. The brainwashing cannot be stopped during meetings, and violent and illegal means are used, which is simply too weak. With the rise of blockchain technology, Ponzi schemes empowered by "blockchain+" can no longer be described as becoming more powerful than a tiger. It is simply like a chicken becoming a tiger. Like the Internet, "Blockchain+" technology has truly improved application scenarios. Ponzi schemes have further upgraded on the second generation basis of "Internet+". Because of major breakthroughs in scenario enhancements and improvements, they have become Ponzi Scheme 3.0. , its characteristics are mainly reflected in the following aspects:
1. Decentralization, no leadership. The smart contract of the blockchain runs automatically, does not require human intervention, and cannot be interrupted by humans. Code rules are hard-coded and cannot be tampered with. In terms of scene improvement, it has solved the biggest pain point of Ponzi schemes for thousands of years, that is, the problem of the leader running away. Because the leader is a program and a code, the blockchain program can exist permanently and no one can delete it. I think this is the biggest breakthrough. This virtual leader is always there. He cannot run away, will not run away, and will not change. The rules will never change, and he will adhere to the Ponzi line for one hundred, one thousand, and ten thousand years. Some people may say that smart contracts can be iterated and can also be manipulated to leave backdoors. That's right, but it can also be done without iteration. Even if it is iterated, it will be transparent and visible, and it will be clear at a glance if there is a backdoor. This is the characteristic of blockchain smart contracts. If you cheat on it, it is equivalent to taking out cheat sheets under the nose of the teacher. No one will participate in such a smart contract once it is online. soAfter technical review and verification, there are no backdoors, fair rules, and irrevocable smart contracts, which can be implemented using blockchain technology. Such reliability, once verified, remains unchanged forever. This is the certainty of smart contracts. For a program, even one character of the code remains unchanged. If it is run a million or a trillion times, the result will be consistent and deterministic.
2. Process transparency. The number of depositors, address account, amount, and time; the number of withdrawals, address account, amount, and time; all are visible. The blockchain has a public ledger function, which can be viewed by everyone around the world, and the ledger data viewed by everyone is exactly the same. Why did Qian Bao lose his position? Because we can't see his backend account, how much money goes in every day, how much money comes out, and the specific details of each transaction. In this way, you can see the evaluation of your redemption ability before depositing money, and the evaluation result is absolutely certain, that is, it will not change after you deposit.
3. Complete anonymity. If you have heard of zero-knowledge proof technology. You can skip this part. To put it simply, many of the things we had in the mathematical knowledge base in the past had no application scenarios after invention. Later, it was discovered that this knowledge is very useful for anonymization. The cryptography technology in the blockchain can effectively achieve identity concealment. As we all know, Zhihu cannot achieve true anonymity in terms of technical structure, but blockchain can.
4. The rules are open and fair to everyone. Deposit one yuan, and withdraw ten yuan as rebate. This rule applies to everyone and will never change. You deposit one dollar, and first withdraw money to the person in front of you, and then the person behind you deposits money, and then withdraws money to you. Fair, right? I have reflected on this many times and think it is still fair.
5. Sustainable iteration. In low-level Ponzi schemes, the leader, product designer, profit distributor, and benefit recipient are often four in one. However, in a blockchain Ponzi scheme, the four roles can be completely separated logically. Achieve sustainable iteration. Through social-based collaboration, 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 don’t need to know anyone. As long as the application is valuable, they can keep iterating. Which centralized project can do this? Even a BAT-level company cannot hire so many professionals scattered around the world. This iterative method of socialization is not affected by changes in a specific person or organization.
Ponzi schemes empowered by "blockchain" use blockchain technology in different scopes, because the technology in this field is still constantly being updated. The applications of smart contracts are these two. The years just add up. The earliest blockchain application is Bitcoin. Some people think that Bitcoin itself has the characteristics of a Ponzi scheme. In 2013, I wrote an answer and pointed out implicitly that this new type of Ponzi scheme will be very lethal because it has the characteristics of a Ponzi scheme. It has the characteristics of no leader, open ledgers, no escape, and open and fair rules. Later, I also discovered that many people around me were much more interested in Ponzi schemes than in blockchain technology.interest. Once they hear that Bitcoin is not a Ponzi scheme, they usually walk away silently before I start talking about blockchain technology. On the contrary, if you tell them that it is a Ponzi scheme, they will then ask where to buy it. ? Of course, there is a lot of controversy over whether Bitcoin is a Ponzi scheme, because the actual application scenarios of Bitcoin are constantly expanding.
In the ICO craze, there are many air coins, which are fake Ponzi schemes and have no application scenarios. People who buy these air coins probably know that they are Ponzi schemes. , but seeing that the packaging was good, I bought it. There are estimated to be hundreds or thousands of such air coins. The scope of the cases involved spans the world, and the amount exceeds tens of billions. These ICOs use smart contracts for subscription and distribution, and then circulate on their own in the secondary market. In this case, withdrawals are not guaranteed, and some people may lose all their money. Many blockchain professionals have always wanted to draw a clear line between these applications, because although these air coins use part of the blockchain technology, there is still a centralized organization or individual behind them, with very few network nodes, and users cannot deposit funds. At that time, it was directly aggregated to an organization or individual (and therefore would be swept away). However, there is no doubt that Aircoin still uses the blockchain for deposits and raising funds, which solves part of the problem of running away and increases the scope and scope of the Ponzi scheme. Communication ability. This is what happens objectively.
Since this year, with the advancement of technology, Ponzi schemes that use smart contracts to achieve more decentralization have begun to surface. Deposits and raises are locked using smart contracts to complete a complete closed loop of deposit, subscription and withdrawal. It can already be a very pure blockchain application. There are some blockchain games that can be openly admitted. After their release, they publicly claimed that they were a Ponzi game. He said: Look, the rules are transparent, the code is visible, and the deposit contract is Locked, no escape, no human intervention, automatic withdrawal. Play early and earn early. This is a crucial breakthrough, publicly admitting that you are a Ponzi scheme, which is something that Ponzi schemes 1.0 and 2.0 could not do before (they did not dare to openly admit that you are a Ponzi scheme). incredible. The gameplay is simple and crude.
This solves a major obstacle in the previous Ponzi scheme promotion process. In the past, it relied on brainwashing to win people's heads, but now it relies on code to speak for itself. You see, "This program won't run away on its own, right? There's no backdoor in it, right? Has the leader disappeared? Even if Satoshi Nakamoto is caught, it won't affect the continued execution of the program, right?" So the first batch of blockchain Ponzi schemes fell into the trap, right? What is important are coders who understand the code, and then these coders stand up and say that after technical verification, it is indeed such an effect, driving other people who do not read the code to join.
In addition to Ponzi scheme application scenarios involving entertainment, gambling, and fraud, blockchain also has opportunities to flex its muscles in Ponzi scheme application scenarios involving the national economy and people's livelihood, and public utilities, and can even be used extremely Dadi enhances people's sense of gain and happiness, and actually improves people's lives. For example, the application of national or global public pension platforms based on blockchain. Because this platform is based on blockchain, it can solve several major shortcomings of pension funds:
1. The problem of fund misappropriation. The ledger is open, and the funds are locked in a decentralized manner. No one can unlock it, except recipients who meet the rules and can withdraw funds. No possibility of appropriation.
2. Inflation problem. The current pension system adjusts coefficients every year based on a series of complex algorithms such as inflation. After adjustment, recipients are often dissatisfied because the total amount has increased, but their purchasing power has decreased. By taking advantage of the fact that virtual currency cannot be issued additionally, the inflation rate can be restrained and all the money received can be guaranteed to be real money.
3. Unpredictable problems. It is difficult for us to predict the pension withdrawal situation in 30 years, but it can be predicted in advance through smart contracts. Stimulate payment enthusiasm.
4. Policy loopholes and fairness issues. Any pension policy targets diverse groups, and there will be unfair situations. Everyone wants to pay less and get more, pay later and withdraw early. The transparency of the blockchain is down to each account, rather than a set of general policies that plug loopholes in the implementation process. Everyone is the same, pay more and get out more, pay early and get out early. It can even be inherited and never lost.
This greatly reduces the burden and cost of managing pensions by the state. Things that the existing pension system can do can still be done after using blockchain technology, such as state subsidies. Just put money into the contract, and it will be locked. There will be no fakes, such as forced payment, and every record will be true and traceable. All in all, all existing systems and rules can be put on the chain, which improves efficiency and output levels and ensures fairness without affecting the existing effects. Moreover, because the cost of the huge management system is reduced, everyone can receive The absolute number may increase a lot, which will have the effect of actually improving people's lives. Again, it will increase the sense of gain and happiness. In the matter of pensions, the subject of our trust has changed from a single national government to a national government + blockchain, and more than 50% of the process has become a fixed software program. Aren’t we more trusting in this way? If the on-chain pension system is 100% implemented, it can even break the national restrictions and be implemented by a piece of code that is honest, cannot cheat, and cannot be tampered with. Automatic deposits and automatic withdrawals. Trusting it is like trusting a dead person. There will be no mistakes.
The design of the next generation to support this generation is a great invention of our human evolution, which has accelerated the speed of social development. On the surface, it seems that the last generation on earth will suffer more, but in fact it is not. Yes, because the last generation of people on earth may not necessarily know that they are the last generation (maybe they know it in the last few seconds, but so what). What’s more, the earth has disappeared, does the last generation of people still need to withdraw funds for retirement? Obviously, no need.
The biggest disadvantage of a Ponzi scheme is that it runs away midway and the funds are broken. Blockchain has a clear technical solution to solve this problem, and it can also be proven and falsified, so , this technology is scientific. Once the disadvantages are eliminated and the benefits gradually emerge, the Ponzi scheme will achieve greater development in the future.
I also want to ask a question. In human history, are there any things that were originally negative or useless? Later, with the development of technology, the disadvantages were eliminated or circumvented, and their functions were discovered, and then they became Be more and more useful and important?
⑵ What is smart parking
Smart parking refers to the comprehensive application of wireless communication technology, mobile terminal technology, GPS positioning technology, GIS technology, etc. to the collection, management, and management of urban parking spaces. Query, reservation and navigation services realize real-time updating of parking space resources, integration of query, reservation and navigation services to maximize the utilization of parking space resources, maximize parking lot profits and optimize parking services for car owners.
The "wisdom" of smart parking is reflected in: "smart parking space + automatic payment of parking fees." Serving car owners' daily parking, staggered parking, parking space rental, car aftermarket services, reverse car search, and parking space navigation.
(2) Extended reading on the application of blockchain in smart parking:
The purpose of smart parking is to make it easier for car owners to find parking spaces, including parking spaces. Wisdom in both offline and online aspects. Online intelligence is reflected in car owners using mobile APP, WeChat, and Alipay to obtain parking lots at designated locations, parking space availability information, charging standards, availability of reservations, charging, sharing and other services, and realize pre-payment and online checkout functions. .
Smart parking is not a new concept. 2015 is known as the first year of smart parking in China. This concept attempts to realize online inquiries and parking reservations through technical support, and supports induced parking, reverse car search, and smart payment. The primary purpose of developing smart parking is to solve parking information asymmetry.
Accelerating the development of smart parking has become an important sub-topic in building smart cities, testing the technological innovation capabilities of enterprises and also testing the city's modern governance capabilities using Internet + traffic management. If every city can implement city-level smart parking solutions, it will not only help resolve the congestion caused by parking inconvenience, but also hope to alleviate urban traffic congestion and make the city more calm.
⑶ How to apply blockchain How to apply blockchain
1. Financial field:
Blockchain is used in international exchange, letters of credit, equity registration and stock exchanges It has potential huge application value in other financial fields. The application of blockchain technology in the financial industry can eliminate the need for third-party intermediaries and achieve direct point-to-point connection, thereby greatly reducing costs and quickly completing transaction payments.
2. Internet of Things and Logistics Fields:
Blockchain can also be naturally combined in the Internet of Things and logistics fields. Through blockchain, logistics costs can be reduced, the production and delivery process of items can be traced, and the efficiency of supply chain management can be improved. This field is considered a promising application direction of blockchain.
3. Public service field:
Blockchain is closely related to people’s production and life in public management, energy, transportation and other fields, but the centralized nature of these fields also bringsSome problems can be solved using blockchain. The decentralized, fully distributed DNS service provided by the blockchain can realize domain name query and resolution through point-to-point data transmission services between various nodes in the network, and can be used to ensure that the operating system and firmware of an important infrastructure are not Tampered, you can monitor the status and integrity of the software, detect bad tampering, and ensure that the data transmitted by systems using IoT technology has not been tampered with.
4. Digital copyright field:
Through blockchain technology, works can be authenticated, proving the existence of text, video, audio and other works, and ensuring the authenticity and uniqueness of ownership. After the rights of the work are confirmed on the blockchain, subsequent transactions will be recorded in real time, realizing the full life cycle management of digital copyright and also serving as a technical guarantee in judicial evidence collection. For example, MineLabs, a startup company in New York, USA, has developed a blockchain-based metadata protocol. This system called Mediachain uses the IPFS file system to realize copyright protection of digital works, mainly for copyright protection applications of digital pictures.
5. Insurance field:
In terms of insurance claims, insurance institutions are responsible for fund collection, investment, and claims settlement, and often have high management and operating costs. Through the application of smart contracts, Can Thanh Orange does not require the policy holder to apply or the insurance company to approve it. As long as the claim settlement conditions are triggered, the policy will realize automatic claim settlement. A typical application case is LenderBot, which was launched in 2016 by the blockchain company Stratumn, Deloitte and the payment service provider Lemonway. It allows people to register customized micro-insurance products through the chat function of Facebook Messenger to provide insurance services between individuals. The high-value items exchanged are insured, and the blockchain replaces the third-party role in the loan contract.
6. Public welfare field:
The data stored on the blockchain is highly reliable and cannot be tampered with, so it is naturally suitable for use in social welfare scenarios. Relevant information in the public welfare process, such as donation projects, fundraising details, fund flows, recipient feedback, etc., can be stored on the blockchain and transparently and publicly disclosed conditionally to facilitate social supervision.
⑷ Can blockchain technology be applied in the transportation industry
Yes, Chongqing Jinwowo analysis:
Blockchain can enable smart cities for the Internet of Things Create potential. Road signs, traffic lights, cars and other moving and stationary objects will be embedded with sensors that will collect data and send it to a system that will reroute buses, streetcars, emergency vehicles and other municipal vehicles , to find the fastest route and avoid traffic jams.
Ultimately reduce traffic congestion, speed up commuting and reduce carbon emissions. Blockchain-secured sensor data could also help drivers find open parking spaces or charging terminals, pay traffic tickets, and report crashes or maintenance issues.
⑸ What is blockchain technology and how it changes business and financial models
What is blockchain arbitration technology and how does it change business and financial models? Joining the EU and NATO is just a cake-cake given by the West to satisfy hunger. In fact, at least in the current conflict between Russia and Ukraine, and before Russia and Ukraine fail to completely resolve the border issue, the dreams of the EU and NATO are just a dream for Ukraine! In Zhuang Ci's view, the positioning of basic subject research centers should be high enough and can be built on the basis of research institutes or universities with good foundations. The government should provide sufficient and stable support funds. An ideal operating model is to follow the example of Japan. "World's Top International Research Center (WPI)" program.
⑹ What is the principle of smart parking system
Smart parking system will inevitably become a major trend in the future. The specific principles are as follows:
1. The parking lot is installed with geomagnetic induction (parking induction) to connect the smartphone entering the parking lot.
2. Establish an integrated parking lot backend management system and integrate real-time data from major parking lots.
3. Realize intelligent services such as automatic parking navigation and online payment of parking fees in the parking lot, and fully deploy a fully automated parking management system to rationally divert traffic flow.
Currently, Dimeng Intelligent Transportation System relies on Dimeng Technology’s rich development experience and strong technology accumulation in the fields of cloud computing, Internet of Things, big data, financial technology and other fields. It already has relatively mature system assistance in smart parking.
⑺ Blockchain applications are in full swing. What scenarios can be deployed in the automotive industry?
In the past 10 years, the automotive industry has been undergoing the most drastic changes in half a century: One is the consumer demand for The demand for electrification and intelligent driving services has increased significantly; the other is that the industry, empowered by the technological revolution, is undergoing a drastic transformation towards the new three modernizations and digitalization represented by "connection, intelligence and sharing".
So how do car companies carry out digital transformation? Judging from the trend of technological changes in the automotive industry in recent years, blockchain technology is becoming the technical base for the automotive industry to build basic trust capabilities in solving consumer technical doubts, strengthening trust, and responding to data security issues.
BMW uses blockchain technology to improve the visibility of automotive raw materials and parts in the global supply chain; Volvo uses blockchain to trace the origin of cobalt materials in lithium-ion batteries, thereby avoiding Purchase cobalt materials from companies that are unethical or have excessive carbon emissions.
The odometer system developed based on the blockchain increases the difficulty of modifying the odometer, because each odometer reading will be permanently stored on the blockchain. In the second-hand car market, the mileage of a car will become more secure and transparent, which will help brands better preserve value.
Empowered by blockchain technology, the vehicle’s charging behavior, driving records, battery consumption and other information are continuously recorded to form a complete life cycle record, laying the foundation for improving battery technology and improving car owner services. Can also be used for carbonTransactions provide sufficient and credible data to contribute to my country’s “carbon neutrality” cause.
Generally speaking, the practice of blockchain in the automotive industry focuses more on tracking and visibility, traceability, and data applications. Car companies regard blockchain as a breakthrough for independent innovation of core technologies, which can accelerate the development of blockchain technology and industrial innovation. We believe that in the near future, more and more car companies will integrate blockchain technology into the innovation and development of enterprises, so as not to fall behind in the wave of digital and intelligent transformation.
⑻ What role can the now popular blockchain technology play in the automotive industry?
Blockchain technology plays an important role in the development of the automotive industry, such as: in the automotive industry The formation of ecological alliances in the supply chain, applications in the second-hand car market, applications in automotive safety, etc.
1. Automotive industry supply chain financial alliance ecology based on blockchain technology
The integrated supply chain information platform based on blockchain technology connects enterprises in the automotive supply network with alliance chains Through the SDPOs consensus mechanism, a chain information system is established to establish a multi-center efficient supply system. Auto parts sources, production processes, sales channel tracking, maintenance records and other important information are all recorded in this chain. The information generated in the automobile manufacturing process will automatically trigger the corresponding smart contract, realize the automatic recording of the transaction information of upstream and downstream enterprises in the power supply chain, and automatically transfer the payment, and ultimately form a system with the automobile product information flow as the main body, the business flow and the logistics flow as the flow and The information structure supported by capital flow enables efficient and accurate storage and traceability of product information.
⑼ Which fields are blockchain suitable for?
The first one is the information security industry.
The second one is the bill business field
The third one is the payment and settlement business.
Fourth, identity/account authentication business.
Fifth, each node participating in the maintenance of the equity proof blockchain can obtain a complete data record. Using the characteristics of reliable and collective maintenance of the blockchain, the rights of the owners of equity can be confirmed.
Blockchain technology is really powerful. With the advancement of the times, this technology may change the development direction and trend of the financial industry, and because the blockchain technology itself has large capacity, high-speed computing, security, and convenience And other characteristics have laid a strong foundation for the advancement and popularization of technology.
⑽ What are the applications of blockchain in the industry
Taking the tourism industry as an example, blockchain applications are mainly concentrated in travel, travel community reviews, digital identity management, credit consumption management, Tracking pilots' professional certificates and qualifications, hotel and airline loyalty programs, reservation management, and consumer points management are several application areas. In addition, with the development of blockchain, many related top domain names have been registered, which has had a relatively large impact on the domain name industry. In addition, blockchain also has applications in finance, games, entertainment and other fields.
