⑴ What are the application scenarios of blockchain
Major companies in the industry: Ping An of China (601318), Donggang Co., Ltd. (002117), Information Development (300469), Yuanguang Software ( 002063), Boss Software (300525), Feitian Integrity (300386), Sifang Jinchuang (300468), Industrial and Commercial Bank of China (601398), SF Holding (002352)
The core data of this article: China’s blockchain downstream applications Structure and scale of China’s blockchain market
The enthusiasm for blockchain investment has eased
The frequency and amount of investment and financing increased sharply from 2016 to 2018. As of October 2018, China’s The number of blockchain company/project financings reached 349, with the total financing reaching 17.078 billion yuan. In 2019, the number of financing events was 149, a year-on-year decrease of 50%, and the financing amount was 3.49 billion yuan, a year-on-year decrease of 75%. Capital investors’ investment in blockchain companies has gradually become more rational. After entering 2020, capital's enthusiasm for investment in blockchain has further declined. In 2020, there were a total of 114 financing events in the blockchain industry, with a financing amount of 6.5 billion yuan.
The above data refers to the "China Blockchain Industry Market Foresight and Investment Strategic Planning Analysis Report" by the Qianzhan Industry Research Institute.
⑵ What important role does blockchain play in mutual aid platforms?
Network mutual aid applications developed based on blockchain platforms can maximize the guarantee of funds and agreements , the absolute security of information and improve risk control capabilities.
1. Transparent fund flow
All fund flow details are recorded on the blockchain. The data cannot be forged or tampered to ensure the authenticity and validity of the data. All regulatory units, public media, and ordinary users can view it at any time. and supervision.
2. Efficient execution of rules
All fund transfers are executed in accordance with public and non-tamperable smart contracts. Once determined, they can be executed accurately and no one can intervene or artificially misappropriate or intervene. Improvement improve the efficiency of rule enforcement.
3. User information security
All personal sensitive information is highly encrypted and stored. Unless authorized by the user, others cannot access or steal it.
4. The service will never go down
The network mutual aid running on the public chain does not depend on whether a certain central server is online, and it can ensure that the services provided will never go down.
At present, Tongxin Huzhu, the first network mutual aid platform to implement blockchain applications in China, will fully apply blockchain technology to network mutual assistance to maximize the security of users’ sensitive information while enhancing the transparency of network mutual assistance and enhancing Trust between mutual aid providers, trust between mutual aid providers and companies, and trust between mutual aid providers and third-party organizations.
⑶ What fields are blockchain suitable for?
The first one is the information security industry.
Second, receipt of bill businessDomain
The third one is payment and settlement business.
Fourth, identity/account authentication business.
Fifth, each node participating in the maintenance of the proof of equity blockchain can obtain a complete data record. Using the characteristics of reliable and collective maintenance of the blockchain, the rights of the owner of the 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.
⑷ What exactly is blockchain? Which blockchains have physical applications
What is blockchain?
Official definition: Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission consensus mechanism encryption algorithm, etc. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.
Vernacular understanding: A block is to package all the data generated within a time period in chronological order. Generally, the length of a block is 10 minutes, which means that within 10 minutes, all the data on the Internet will The data is packed into a complete package, and this complete data package is called a block. The blockchain links these data packages in order to form a structure, and cryptographically ensures that it cannot be tampered with or forged to form a distribution. ledger, this is the blockchain.
It seems that everyone has a preliminary knowledge and understanding of the blockchain. So whether the blockchain has any practical application in daily life, the answer is yes, the current practical application There are mainly the following aspects. Of course, I may not know some of them. Friends are welcome to leave messages to add.
Financial Industry
Blockchain should be used the most in the financial industry.
For example, in May 2017, OMG (Omise Coin) announced that it would cooperate with Alipay to launch an electronic wallet, integrating the "Alipay" payment solution into its own payment service suite to help local electronics in Thailand. Business merchants accept online payment transactions from Chinese tourists.
Another example is PPT, which is a financial transaction system for bills based on blockchain.
Gaming
The gambling industry entered the blockchain probably last year. Why does gambling favor blockchain? Because blockchain provides a relatively fair betting system. Why? It is relatively fair. As can be seen from the previous introduction, the blockchain cannot be tampered with or forged.
For example, WICC (WikiChain) can realize rich application scenarios such as asset issuance, betting applications, copyright traceability, mutual insurance, decentralized exchanges, and cross-border settlement.
For example, the STX (King of Fighters Token) stox application is designed to provide the full functionality of a prediction market application without the need for any central server. Prediction markets require events such as event planning, market production, andTraders provide information and analysis, reporting event results, and of course collection and payment functions.
I believe that if the current lottery industry is built on the blockchain, people will become more and more enthusiastic about buying, because there are too many insider tips that make people give up.
Internet of Things
The Internet of Things still has many applications on the blockchain, because the traceability and immediacy of blocks are very suitable for this industry.
For example, DATA is the concept of the Internet of Things. It is a decentralized p2p network. Data sources can connect to any node in the entire network, then publish data, and the network will immediately send it to subscribers. Horizontal scalability is achieved through sharding pattern. This timeliness and accuracy are very important in IoT applications.
Game industry
For example, GTC (G coin) is a decentralized digital asset based on Ethereum erc20 issued by Game Global. G coin is committed to becoming a universal number in the global game industry. Monetary standards.
For example, MANA is a distributed shared virtual platform. On this platform, users can browse and discover content and interact with other people and entities. Users can also claim ownership of virtual territories through a blockchain-based land ledger. The territory is demarcated by rectangular coordinates (x, y), and its owner can decide the content published on the territory, including static 3D scenes to interactive systems such as games.
There are many other industries. The emperor did not list them one by one, but listed a few representative ones. What is the purpose? It shows that the blockchain is definitely not just a currency transaction, it is a real implementation project, and it is a product of the changes of the times with real practical uses.
The development of human society is actually like the blockchain, it is irreversible and unstoppable. As far as I feel, the blockchain will enter thousands of households sooner or later. Regardless of whether it is bull or bear, hold it in your hands. Value coins and Flush have started quoting digital currencies, which shows that society is accepting it step by step. The power of social development cannot be blocked by any country or person.
⑸ How to define blockchain and what are the application scenarios of blockchain?
Nowadays, many people think that blockchain is a universal technology that can do anything, which is somewhat different. Blockchain technology is a myth!
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 distributionA database storage system that can operate collaboratively around the world is different from traditional database operations where read and write permissions are in the hands of a company or a centralized authority (centralized characteristics). Blockchain believes that anyone with the ability to set up a server Everyone 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, those 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 worth more than 20,000 US dollars, which has skyrocketed by more than a thousand times. This has also benefited a large number of wealthy people. Currently, there are blockchain The virtual currency generated by technology is gradually entering 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 become classic, and others To say that everything is hype 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 rights process takes a long time,Obtaining evidence is difficult and costly, and it is 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 roles and responsibilities of public administration have not changed significantly – or rather, what has changed dramatically is actually the scale 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 facing this issue head-on.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 observed that "Proof-of-work systems are not suitable for such large transaction processing systems because they assume that all transactions in the system are There is a need for openness and observability to a certain extent.”
3. Digitization and intellectual property
Governments are responsible for maintaining copyright records and databases. These records prove ownership of intellectual property. A blockchain-based system would allow artists, performers and writers of all kinds to time-stamp their works and theoretically detect copyright infringements and even keep a permanent record of their rights. In fact, many governments have already 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 system that can be used to protect online copyrights." He also added that "the relevant procedures will Released soon to users in an easy-to-use format."
This work is still in the early exploratory stages, but it offers enterprise customers the possibility of preserving records through replication technology. From a theoretical level, companies can use blockchain solutions to conduct financial accounting and discover 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 need government support and assistance to ensure that they are able to sustain themselves and develop. However, welfare distribution is neither simple nor often straightforward. Problems such as corruption and impersonation have been wreaking havoc on various distribution channels within government schemes.
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. Bidding activities
In order to build public infrastructure or provide related services, the government hopes to achieve economies of scale and competitive gains through bidding as much as possible. However, the bidding process is often not fair or transparent. Public procurement has long been a major scene of rampant corruption around the world. Transparency International noted that “many governments will award project contracts to a certain supplier in the absence of fair competition. This allows companies with greater political resources to improperly win over competitors; or companies in the same industry Bids will be negotiated in advance between companies, ensuring that each company gets a share of the tender. This will significantly increase the cost of delivering services to the public - 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 anything else that needs to be tracked. Transparency of financial processes. 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 internal affairs and The Ministry of 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 companies and governments. The key here, of course, is implementation;And we should also look at all this 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!
Blockchain in layman’s terms Just like the 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. Each node keeps accounts separately. The failure of one or two nodes will not affect the entire network.
How is this distributed network different from the distributed servers of Google Network? Google Network's distributed servers still belong to 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 someone who will turn on the machine as a new node to support the network.
After the popular and technical explanation, I hope you understand. So the first application scenario is finance. I put my money in Alipay. If Alipay doesn't recognize it one day, there's nothing you can do. But on the blockchain, it is useless if one node does not acknowledge it, because other nodes still have my records. The second is the contract. Nowadays, contracts are made on paper and are easy to be faked. But if they are put on the blockchain, they cannot be faked.
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. .
Blockchain technology was first used in Bitcoin. Blockchain provides a reliable and trustworthy means of organizing data for cross-subject business scenarios. JD.com is essentially a supply chain company, and blockchain technology will be first used in many scenarios of the supply chain.
Blockchain is a decentralized technology. Blockchain can be applied to all products currently covered by the Internet.
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 digital advertising traffic fraud 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 toPeople get along with each other 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 we 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 cryptographically guaranteed to be non-tamperable and non-tamperable. Fake distributed ledger.
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. . From digital currency to securities and financial contracts, medical care, and games, artificial intelligence, smart contracts, Internet of Things, e-commerce, file storage and other fields can be widely used.
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.
⑹ What are the specific application scenarios of blockchain?
Taking the tourism industry as an example, blockchain applications are mainly concentrated in tourism. Application areas include travel, travel community reviews, digital identity management, credit consumption management, tracking professional certificates and qualifications of pilots, hotel and airline loyalty programs, reservation management, and consumption points management
< p>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 industryIn addition, blockchain also has applications in finance, games, entertainment and other fields< /p>
⑺ In what scenarios will blockchain be applied?
According to reports, blockchain finance has made great progress in these two aspects in recent years. The first The breakthrough is to be able to establish a multi-dimensional three-dimensional interactive architecture. The second breakthrough is to be able to establish an open source, public and trustworthy data registration and certificate storage platform.
In the future, the financial field should be one of the most important areas for blockchain applications. In addition, Li Lihui believes that with the scale of blockchain, blockchain will be used in logistics, public services and The field of social management can also be widely used. This kind of system can provide services for both finance and non-financial services.
In terms of future development, there are actually two forms: multi-center and decentralization." Li Lihui said that the decentralized distributed system will be applied in some small-scale virtual communities, including the Ethereum community. , Bitcoin community, and large-scale applications should be a multi-center distributed ledger system.
However, the value of a single blockchain application is limited, and blockchain technology must Only when integrated with big data, artificial intelligence, cloud computing, and 5G and 6G technologies can we be more efficient and create more value for society.value.
