1. How to define blockchain and what are its application scenarios
Many people now think that blockchain is a universal technology that can do anything. It’s a bit of a myth about blockchain technology!
Regarding the definition of blockchain technology, American scholar Melanie Swann defined blockchain technology as an open, transparent and decentralized technology in her book "Blockchain: A New Economic Blueprint and Introduction" database.
Definition of Blockchain: Narrow VS Broad
As for the application scenarios of blockchain technology, it is natural to combine the differences between blockchain and other technologies. In terms of system characteristics.
Blockchain technology features include:
Blockchain is a global A database storage system that can be operated collaboratively in various places is different from traditional database operations where read and write permissions are in the hands of a company or a centralized authority (a characteristic of centralization). Blockchain believes that anyone with the ability to set up a server can participate. Nuggets from all over the world have deployed their own servers locally and connected to the blockchain network to become a node in this distributed database storage system; once joined, the node enjoys exactly the same rights as all other nodes and obligations (decentralized, distributed characteristics).
At the same time, people who provide services on the blockchain can perform read and write operations on any node in the system. In the end, all nodes around the world will complete the process again and again according to a certain mechanism. Synchronize in sequence to achieve complete consistency of data in all nodes in the blockchain network.
At the beginning of this year, the term blockchain began to enter everyone’s lives. From national leaders to aunts who dance square dances, everyone knows this term. This term is widely known by Bit Brought by coins.
As we all know, the first few dozen bitcoins could only be exchanged for one pizza. At its peak, it was more than 20,000 US dollars each, which has skyrocketed by more than a thousand times, which has also benefited a large number of wealthy people. Currently, there are blockchain The virtual currency generated by technology is gradually entering into everyone's life, and many people have joined the ranks of currency speculation. I often hear people say that if you buy the right currency a hundred times, a bicycle will become a sports car, and one coin will turn a young model. You can imagine how many of them are involved. Attractive.
Since 2008, various games applying blockchain technology have also become popular, such as development games (Network Letts Dog, 360 Block Cat), mining games (NetEase Planet, Virtual Earth, Gongxinbao), these are attracting everyone to join in the name of blockchain, and of course there are some that are really reliable, which requires everyone to identify them carefully.
The three words "blockchain" were completely ignited during the Spring Festival that just passed, and the limelight overshadowed everything else. Some people said that this is the arrival of a new era, and the past has becomeClassical, and some people say that everything is hype and is ultimately a bubble.
In fact, blockchain technology is not a new concept. It has been applied to many industries, such as electronic signatures, as early as the past two years. Recently, the third-party electronic signature platform eShanbao revealed the latest progress of blockchain applications to NewSeed.
Currently, blockchain technology is mainly used in e-signing products for certificate deposit and certificate issuance. The application scenarios include copyright protection and online signing. , web page forensics, phone recording, email storage of evidence, etc.
Take the rights protection of online works as an example. Since online rights protection generally adopts the method of collecting evidence after the fact, real-time confirmation of rights is not carried out in the process of evidence generation, so the entire confirmation process is difficult. The copyright process is time-consuming, difficult and costly to obtain evidence, and extremely difficult to prove and trace the source. It cannot meet the characteristics of rapid dissemination and large quantity of online works.
eShanbao's new intellectual property protection solution based on timestamp + blockchain starts from the user's real-name authentication and solidifies the information generated in the process in real time. Electronic data, and through the time source service synchronized with the National Time Service Center, online works are stamped with legally valid timestamps to prove that electronic files have not been tampered with in a certain period of time. Blockchain technology can establish point-to-point trust in the network, ensuring that all blockchain nodes can record complete copyright confirmation and transaction records, and can trace their origins, truly realizing anti-repudiation and anti-tampering, and realizing a kind of distribution. trust infrastructure.
Founder and CEO Jin Hongzhou believes that the application of decentralized blockchain technology has greatly improved the efficiency of data storage and certification, and The credibility of the identity of the parties reduces the cost of trust, but it cannot replace the original centralized public key encryption technology. The two should complement each other. Through the combination of the two, it can provide users with real-time and reliable Confirmation plan.
Next, e-Shanbao will also focus on building a smart contract platform based on blockchain technology. Jin Hongzhou said that data storage, Issuing certificates is only a relatively superficial application based on blockchain technology. It is the first step to implement blockchain technology, and the realization of real smart contracts is the second step. "Smart contracts cannot simply be understood as electronic contracts. They refer to a process, from the conclusion of the contract to the confirmation to the final execution." Jin Hongzhou explained.
Through the following limited cases, I hope everyone can understand the actual performance of blockchain technology, thereby stimulating interest in such solutions.
1. Administrative Services
Over the centuries, the role and functions of public administrationAccountability has not changed significantly – rather, what has changed is the size of the data and the specific ways in which public agencies handle it. Although various digital technologies already exist to help collect and process data, issues such as anonymization, portability, and the immutability of large amounts of data remain unresolved.
Sasha Ivanov, founder, entrepreneur and CEO of Waves Platform and Vostok projects, said, "What the public administration currently lacks is a more convenient user experience (UX) for data use. To improve the user experience , we should introduce some kind of layer to it that acts as a trusted public environment that is transparent and can store data anonymously and immutably."
Governments are working on this by launching the U.S. Federal agency and enterprise-level initiatives such as the Federal Blockchain Initiative are gradually confronting the existence of such problems. The United States held its first federal government blockchain forum in July 2017, and the U.S. General Services Administration currently has more than 200 related use case repositories. Ivanov explained, “Distributed systems can really help us build such a reliable environment, improve our big data work, and even integrate all emerging technologies – including artificial intelligence and the Internet of Things. In fact, , whenever we face any kind of technology, it always embodies the sum of certain other technologies."
Now, the system supported by the blockchain can actually work - this This view has been unanimously recognized by all experts and has become the most important theoretical basis. In other words, what we need to do next is create more production-ready solutions.
2. Payment services
The government needs to process transactions, many of which involve the exchange of funds with citizens. Blockchain technology has huge potential application value in reducing the cost of fund transfers - including using new blockchain-based cryptocurrencies as intermediate transaction carriers, or using blockchain as a means of fund transfer, etc. Once a perfect solution is discovered, the business opportunities will be endless - especially for those who need to conduct frequent cross-border or Internet transactions.
The Jasper project was developed by the Bank of Canada to help it further think about how central banks and other financial institutions should implement payment operations between different banks based on distributed ledgers. The Bank of Canada has also developed its own digital currency variant, “CAD Coin,” to test the feasibility of using a national currency on top of the blockchain.
This project brings to an interesting conclusion that we should say no to proof-of-work public chain systems. In a paper titled "Project Jasper: Is a Distributed Batch Payment System Feasible?" the author observes that "proof-of-work systems are not suitable for such large transaction processing systems because they assume that allTransactions require openness and observability to a certain extent. ”
3. Digitization and Intellectual Property
The government is responsible for maintaining copyright records and databases. These records prove the ownership of intellectual property. A blockchain-based system allows various artists, Performers and writers can time-stamp their works and theoretically detect copyright infringements and even retain permanent records of rights. In fact, many governments have taken important exploratory steps in this direction.
Iran recently announced that it will deploy this technology. "Iran Financial Tribune" quoted Morteza Mousavian as saying that "the Digital Media Department of the Ministry of Culture has reached an agreement with a blockchain company to jointly design a usable A system for protecting online copyright. "He also added, "Relevant programs will soon be released to users in an easy-to-use manner. ”
This work is still in the early stages of exploration, but it provides corporate customers with the possibility of preserving records through replication technology. From a theoretical level, companies can use blockchain solutions for financial accounting, And discover the errors in real time.
4. Welfare distribution
The government has the responsibility to create a level playing field for citizens. Citizens who are chronically poor or economically disadvantaged certainly Government support and assistance is needed to ensure that they are able to maintain their lives and acquire the ability to continue to develop. However, welfare distribution is neither simple nor often straightforward. Problems such as corruption and imposters have been seriously undermining government programs. Various distribution channels.
In China, the National Council of Social Security Fund is conducting early research on how to use blockchain technology to improve the delivery of national benefits to citizens. At the same time, India is also taking action , Andhra Pradesh and Telangana are already using blockchain to support their civilian resource supply systems.
It is said that many companies, including Microsoft, are also considering using the same technology. These solutions, which will touch individual employees and functional roles, are expected to gradually appear in small businesses in the near future.
5. Tendering activities
In order to build public infrastructure or provide For related services, governments hope to achieve economies of scale and competitive gains through tendering as much as possible. However, the tendering process is often not fair or transparent. Public procurement has long been a major scene of rampant corruption around the world. Transparency International pointed out, “Many governments will award project contracts to one supplier in the absence of fair competition. This allows companies with greater political resources to unfairly outcompete competitors; or companies in the same industry negotiate bids in advance to ensure that each company gets a piece of the tender pie. This will significantly increase the number of services provided to the publicCost – We have found that corruption issues can increase project costs by 50%. ”
So, how can blockchain technology solve the bidding problem? According to Ivanov, “Unlike decentralized centralized systems, independent ledgers powered by blockchain will be able to improve bidding or Transparency of any other financial processes that need to be tracked. The intervention of blockchain technology will help track the use of funds and ensure that they are paid out as expected and within the allowed time. ”
Currently, Japan’s Ministry of Interior and Communications has announced a blockchain-based bidding system, which means that in industries with serious collusion problems, small and medium-sized enterprises are expected to usher in a more transparent bidding method and Brighter development prospects.
Although quite a few of the cases mentioned previously are far from finalized, they do provide many possibilities for enterprises and governments. Of course, the key lies in implementation; and we All this should also be viewed with optimism, that is, although blockchain technology is often misunderstood by people, it is and will eventually find a direction in which it can exert its own energy!
In layman's terms, blockchain is like There are more than a dozen beacon towers on the Great Wall. If an enemy comes at one place, they will send out smoke. The other beacon towers will know about it and enter a defensive state together. In technical language, it is a distributed ledger, and each node will keep accounts separately. The failure of a single node will not affect the entire network.
How is this distributed network different from the distributed servers of Google Network? Google Network and others The distributed servers still belong to the Google network and are controlled by their central scheduling algorithm. The distributed nodes in the blockchain do not know each other and have no legal affiliation. If you want to go offline and shut down That's fine, but because of the currency rewards, there will always be people who will start up as new nodes to support this network.
After the popular and technical explanation, I hope You already understand. Then the first application scenario is finance. I put the money in Alipay. If Alipay doesn't recognize it one day, there is nothing you can do. But on the blockchain, it is useless if a node does not recognize it. Because other nodes still have my records. The second one is the contract. Nowadays, contracts are signed on paper, which is easy to forge, but it cannot be forged if it is placed on the blockchain.
There are more application scenarios. It is recommended to check the top 100 digital Huobi online to understand the corresponding projects behind them and become a blockchain expert.
Area Blockchain technology was first used in Bitcoin. Blockchain provides a reliable and credible means of organizing data for cross-subject business scenarios. JD.com is essentially a supply chain company, and blockchain technology will first be used in the supply chain in many scenarios.
Blockchain is a decentralized technology. At present, the InternetBlockchain can be applied to all products that can be covered.
The most popular application industry at present is the financial industry.
An application that has been implemented is product traceability. Alibaba and JD.com are already using blockchain technology to fully trace the origin of some of the products they sell. Consumers can trace the origin of the purchased products. There are also many blockchain applications in the digital advertising industry. Since traffic fraud in digital advertising causes losses of tens of billions of dollars every year, there are already blockchain application projects based on digital advertising, such as DCAD, which is based on blockchain. The digital advertising application of blockchain technology mainly solves the problem of traffic fraud
In the future, as the application of blockchain technology becomes more mature, it will be applied in many industries, creating a new ecosystem based on technological trust. Mode
The characteristics of blockchain are distributed accounting and decentralization, but the ultimate goal is to make people get along more equally. Technology is meaningful only when it serves human values, and technology that meets human value needs will develop. Therefore, blockchain is in line with human pursuit of freedom and equality, so its trend to become mainstream is unstoppable.
Currently, there are many blockchain gimmicks, which are basically used to issue coins. The newly launched ono is a decentralized, free and global social platform. Due to decentralization, your chat communication information is peer-to-peer and cannot be viewed by others. In other words, your every word and deed will no longer be recorded and reviewed at any time like it is now on WeChat, QQ, and Facebook, freeing you from the trouble of surveillance.
In fact, blockchain technology can be used in any field. Information that previously required third-party confirmation can be completed online and confirmed at multiple nodes, making it difficult (almost impossible) to delete.
At present, blockchain is still in its infancy, and the technology is not mature enough, but it is also a better time to enter.
What is blockchain If you use non-technical terms to explain blockchain, blockchain is a place where data is stored. However, the data stored in the blockchain is safe and reliable and does not need to be managed by anyone, so In the Internet, a place where data and information are exploding, having such a place would be like a magical treasure.
If you ask what the blockchain can do, it is better to say what applications require the use of the blockchain. As mentioned earlier, blockchain is a safe place, so wherever data needs to be protected securely on the Internet, blockchain technology needs to be used. For example:
Because the use of blockchain technology can better protect the data of policyholders, in today’s Internet, data is value and wealth, so value protection and value transmission are the future development directions of the Internet. And blockchain technology can really do just that.
If there are any deficiencies, you are welcome to comment and correct me.
In a narrow sense, blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is distributed cryptographically to ensure that it cannot be tampered with or forged. Account book.
The two parties involved in the transaction do not need to know who the other party is, nor do they need a third party for trust endorsement. They only need to trust a common algorithm to establish mutual trust and conduct direct transactions.
Its characteristics are trustlessness and decentralization. The destruction of each node's ledger has no impact on the entire blockchain. The blockchain runs point-to-point payments without a center that may cheat, and the security is greatly improved. Improved, the entire transaction network has changed from a star structure to a point-to-point P2P structure.
In the future, blockchain will be used in many fields and will have a great impact on human life. . It can be widely used in fields ranging from digital currency to securities and financial contracts, medical care, games, artificial intelligence, smart contracts, Internet of Things, e-commerce, file storage and other fields.
1. Cloud storage
This is the statistics of current cloud storage on the Internet. In terms of volume, Google has the largest volume, which is 8,000PB. So what if we share the idle data on the Internet?
Starlight Cloud builds a blockchain data computing and storage lake through Starlight Chain, with a total storage capacity of 15,000P (approximately 15.72864 billion G) in the future. This will be more than 10 times that of Alibaba Cloud's 1500PB! It is also more than four times the size of the Taizhou Storage Center, the largest storage lake in the world after expansion.
2. Medical aspects
Using blockchain technology to save personal medical records also retains personal medical historical data, which can be used when seeing a doctor or planning for your own health in the future. Historical data can be called directly. These data are highly private, and the use of blockchain technology also helps protect patient privacy.
2. What is the popular explanation of blockchain? You must know these five application scenarios of blockchain!
Recently, blockchain has become popular overnight, and everyone around is discussing blockchain.
So, is the blockchain the same as Bitcoin?
In fact, Bitcoin and blockchain are not the same thing.
Blockchain is the underlying technology of Bitcoin, but the first usage scenario after the birth of blockchain is Bitcoin.
Bitcoin is just a string of data in a computer. Compared with paper currency, it is also called a "virtual currency". To put it simply, you can understand that Bitcoin is just a string of numbers with cash value, similar to Q coins. In other words, Bitcoin has no actual value; it currentlyThe value of Bitcoin is supported by the faith of currency speculators. If the faith is gone, the value of Bitcoin will collapse.
What is blockchain? What are the characteristics of blockchain technology?
Let’s first take a look, why is blockchain called blockchain?
Data is stored piece by piece, and the data stored piece by piece is called a block. Different blocks are linked to the previous block, which is called a blockchain.
For example:
On a certain day of a certain year, Lao Wang lent Xiao Wang 10,000 yuan. Lao Wang told everyone around him the news , the transfer records were posted on WeChat Moments, and everyone helped them testify to the existence of this transaction.
Lao Wang and Xiao Wang are two nodes. These two nodes generate transaction time, location, person and other information, and they are packaged to form a "block". Lao Wang’s friends are also nodes. These nodes jointly record the transaction status and details (blocks) of the two nodes Lao Wang and Xiao Wang. These blocks are connected to form a blockchain.
Fundamentally, blockchain is a distributed ledger database.
What does distributed ledger mean?
Let’s take a look at the traditional accounting method.
The traditional accounting method is a centralized accounting method. For example, if Lao Wang lent 10,000 yuan to Xiao Wang, if Lao Wang did not tell the world about this money, then this amount would Only Lao Wang knows about the money transactions, Xiao Wang knows, God knows, and Earth knows. This accounting method is a centralized accounting method. This method has a very fatal shortcoming: what should I do if the other party does not acknowledge the account? In fact, in real life, in spontaneous private lending relationships, there is no evidence when the lending relationship occurs, resulting in many cases where the other party does not acknowledge the debt afterwards.
The accounting method adopted by Lao Wang from the beginning has prevented future troubles. This method is the blockchain distributed ledger, which has the characteristics of decentralization and allows everyone to It is the center and everyone can testify to the existence of this deal.
In addition to the characteristics of decentralization, blockchain also has the characteristics of being immutable. In the blockchain, if the data in any one block changes, even if it only changes a punctuation mark, it will become invalid and needs to be recalculated. Therefore, in the blockchain technology, once a piece of data changes, the cost will be Very big. Unless all nodes in this blockchain have 51% control. Therefore, the blockchain system will be stable and secure.
It’s still Lao Wang and Xiao Wang. If Xiao Wang wants to default on his debt, he can’t tamper with it unless he bribes everyone in the world who knows about the transaction.
Blockchain is also open and transparent.
In blockchain technology, all data is public, which is still the case of Lao Wang and Xiao Wang.
If Xiao Wang does not accept the money, once this news is released, then Xiao Wang’s reputation will be ruined. He can only pay back the money to release new news and wash out the money. Clear your own identity.
Some people say that if the blockchain is so powerful, will my identity information be revealed and there will be no privacy? In fact, the blockchain has the characteristics of anonymity, which protects our privacy very well. Unless required by legal regulations, technically speaking, the identity of each block node does not need to be disclosed or verified, and can be done anonymously.
What are the applications of blockchain?
The origin of blockchain is to solve the problem of trust, and one of the most successful applications of blockchain is digital currency. Bitcoin is arguably the most successful application of blockchain so far.
In addition to digital currency, the future applications of Bitcoin are still very wide, and blockchain technology has been widely used in different industries. Such as product traceability, copyright protection and transactions, payment and settlement, Internet of Things, digital marketing, medical care, etc., promoting different industries to quickly enter the "blockchain+" era.
1. Payment and clearing
The role of the intermediary bank can be abandoned, point-to-point payment can be realized, intermediary fees can be reduced, and fund utilization can be accelerated.
2. Product traceability
For example, if we buy a piece of clothing on a certain website, we can see the past and present life of this piece of clothing.
3. Securities trading
Traditional securities trading requires the coordination of four major institutions, which is inefficient and costly. Blockchain technology can independently complete one-stop services.
4. Supply chain
Introduce blockchain technology into the supply chain system, synchronize information within the system, control all links, and better complete division of labor and collaboration. , to facilitate accountability afterwards.
5. Intellectual property rights
With copyright on the chain, our photographic works, musical works, literary works, etc. will become our information, and the ownership of the information will be confirmed and become our property.
3. What is blockchain ppt
From an academic perspective, blockchain is a new type of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Application mode. Blockchain is essentially a decentralized database.
For example, if you are a woman, every time your boyfriend says something disgusting to you or promises to buy you something, you immediately record it and send it to all your best friends, classmates, Colleagues, as well as various groups and circles of friends, he can no longer deny it. This is called a district.Blockchain.
The core advantage of blockchain technology is decentralization. It can achieve decentralized credit in a distributed system where nodes do not need to trust each other by using data encryption, timestamps, distributed consensus and economic incentives. Point-to-point transactions, coordination and collaboration, thus providing solutions to the problems of high cost, low efficiency and insecure data storage common in centralized institutions.
The application fields of blockchain include digital currency, certificates, finance, anti-counterfeiting and traceability, privacy protection, supply chain, entertainment, etc. With the popularity of blockchain and Bitcoin, many related top domain names have been registered. , which has had a relatively large impact on the domain name industry.
4. 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 firstThe brain 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. Therefore, after 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 logically separated. 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 social iteration method is not subject to a certainThe impact of changes to specific people and specific organizations.
Ponzi schemes empowered by "blockchain" use blockchain technology in different scopes, because the technology in this field is still constantly being updated. Applications such as 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 that implicitly pointed out 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 more interested in Ponzi schemes than in blockchain technology. 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 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? The leader has disappeared, right? Even if Satoshi Nakamoto is caught, it won't affect the continued execution of the program, right?" SoThe first batch of people to be hooked in the blockchain Ponzi scheme were coders who could understand the code. Then these coders stood up and said that after technical verification, it was indeed such an effect, driving other people who did 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 enthusiasm for payment.
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.It has accelerated the speed of social development. On the surface, it seems that the last generation of people on the earth will suffer more. In fact, it will not, because the last generation of people on the earth may not necessarily know that they are the last generation (maybe they will know it in the last few seconds, but So what), not to mention that the earth has disappeared, will the last generation 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 avoided, and the functions were discovered. And then become more and more useful and important?
