1. What are the service applications that use blockchain technology?

Blockchain technology has a distributed ledger that cannot be tampered with, ensuring the transparency and sharing of information, thus making The cost of establishing trust and reaching consensus between peers in business activities has dropped significantly. This article provides an in-depth interpretation of four typical business scenarios: supply chain finance, commodity traceability, technology and medical care, and industrial Internet.
1. Blockchain adds supply chain finance. Today, the supply chain of most commodities, from the provision of raw materials to the manufacturing of finished products, involves several upstream and downstream small and medium-sized enterprises; and these enterprises are faced with the challenge of unlocking supply chain working capital. pressure. Supply chain finance refers to banks and other financial institutions making systematic financing arrangements for all member companies of the supply chain, thereby forming a win-win situation for core buyer companies and suppliers: the buyer optimizes working capital, and the supplier generates additional operating cash flow, thus Minimize risk throughout the supply chain. There are three pain points in traditional supply chain finance: 1. Information cannot be shared, efficiency is low, and credibility is poor; 2. Bill circulation is inconvenient, contract settlement is slow, and there are often financial risks; 3. Credit cannot be transferred and financing is difficult. The blockchain can realize the following functions: 1. Sharing transaction data, receivables and payables data among core enterprises, multi-level suppliers, and financial institutions while protecting commercial privacy; 2. Transfer of corporate claims and automatic settlement of funds, accelerating corporate recovery. Payment and repayment; 3. The core enterprise's payment commitments flow among multi-level suppliers and financial institutions to convey the core enterprise's credit.
2. Blockchain traceability In the field of commodity traceability, blockchain and Internet of Things technology are combined to trace the entire process of commodity circulation to prevent unscrupulous traders from taking advantage of the information asymmetry in the commodity chain to produce counterfeit and inferior commodities. Shoddy goods. This prevents certain participants from tampering with data or falsely claiming that information is lost when circumstances are detrimental to them, making it difficult to provide evidence and pursue accountability. In addition, blockchain traceability can open up information islands in different links of the supply chain and improve the collaboration efficiency of the supply chain.
3. Blockchain helps medical services Blockchain technology can open up multiple links such as hospital prescription issuance, pharmacist review, drug distribution, drug payment, and process supervision. Through blockchain distributed storage and accurate matching of information on the chain with patients, the one-time dispensing effectiveness of prescriptions is ensured, prescription modification or abuse is prevented, and supervision is facilitated. In the future, patient information, prescription information, drug circulation information, etc. will be encrypted and desensitized through blockchain technology, which can open up more medical application scenarios.
4. Integration of Blockchain and IoT Industrial Internet At the 5th World Internet Conference, the supET Industrial Internet platform, which integrates Internet of Things and blockchain technology, was selected as the world's leading Internet scientific and technological achievement and became the only The award-winning industrial Internet platform.

In addition, blockchain data sharing, blockchain judicial chain, blockchain charity, trusted digital content copyright services, etc. In areas such as government, finance, industry and logistics, healthcare, retailand the Internet industry, blocks have a wide range of business application scenarios.

2. What are the application examples of blockchain technology

Application of blockchain technology in voting
Kuaishang is the first to apply blockchain technology nationwide In the field of voting, it effectively solves the problem of trust in voting data, provides the most authentic and effective data to activists, protects the rights and interests of real voting users, and at the same time makes blockchain technology "people-friendly" so that ordinary people can quickly perceive and enjoy it in the field of life services. The convenience brought by blockchain technology.
The application of blockchain technology in digital asset registration
The Golden Master Digital Asset Service Platform is the first to use blockchain technology. This technology is a global distributed ledger technology that is traceable and non-transitory. Tamper-proof and unforgeable properties. The digital assets of the platform come from regulated digital asset issuers, and the value of the assets is determined through the open market to avoid overestimation or underestimation of value.
The application of blockchain technology in the financial industry
Ant Financial’s independently controllable financial-grade commercial blockchain platform has been deployed globally in multiple institutions and countries in multiple social and commercial application scenarios. Ant Blockchain Chain platform transactions support second-level confirmation, and the consensus mechanism uses an efficient parallel consensus algorithm to ensure the high performance of the blockchain platform. Ant Blockchain has already had multiple production-level applications, applying leading technology to people's livelihood and business. , finance and other fields.

3. What are the current applications of blockchain?

What is blockchain technology? People in each industry have different understandings, and relevant explanations are gradually emerging due to more and more real-life applications. With the popularization of this blockchain technology, the related results are getting bigger and bigger. If we want to understand this technology, we must have an in-depth understanding of reality.

my country's current economic and social credit environment is still relatively weak and credit costs are high. Blockchain technology proposes a set of lower-cost "trust" solutions to reduce the credit costs of the whole society, which is very important for promoting our country. The development of credit economy is of great significance. Although this technological innovation in the field of Internet finance is not yet mature, many large international banks have rushed to invest resources in research and development, which should attract the attention of my country's banking industry and regulatory authorities.
(1) As for commercial banks, they should prepare technology and talent reserves and actively participate in the formulation of international standards.
In order to prevent digital currency risks, my country’s commercial banks are currently unable to conduct digital currency transactions, and research on the technological innovation behind digital currencies is also lagging behind. This is slightly asymmetrical with my country’s private enthusiasm for blockchain research and development. . Nowadays, the development of emerging models of disintermediation such as blockchain technology and P2P is gradually moving from concept to application, driven by the joint innovation of large global financial institutions. my country's major banks should also pay close attention to the latest innovation trends of international peers and join the research as soon as possible. , develop the ranks of blockchain products and promptly adjust development strategies to adapt to the business operation model of Internet finance under the new situation. First, an R&D laboratory can be established, or it can be combined with financial technologyCorporate cooperation. In addition to developing different blockchain application scenarios, it can also be combined with national conditions and inclusive finance, such as studying how to use blockchain technology to achieve low-cost fund transfer payments in economically underdeveloped areas and improve financial services in these areas. The second is to actively participate in the formulation of international standards and agreements, strive for the right to speak, and avoid being a passive follower.
(2) Regulatory agencies also need to continue to pay attention to the development of the latest Internet technology and be prepared to respond.
First, the "decentralization" brought by blockchain technology does not mean that centralized organizations are not needed in economic operations. Blockchain technology hopes to break privileges and human manipulation and allow computer algorithms to achieve "free credit notarization." But from a practical point of view, theoretical deductions cannot be completely mapped to real life. For example, due to the lack of supervision, digital currency transactions such as Bitcoin face high risks of speculation and money laundering. Therefore, if blockchain technology wants to become a new channel for capital circulation, it needs supervision and implementation standards to protect the interests of all parties in the market. In this regard, regulatory authorities should formulate relevant standards and specifications, especially operating specifications, and use their power to ensure that financial innovative products are used rationally; at the same time, they should also improve the protection of consumer rights and interests, strengthen education on the protection of financial consumer rights and interests, and improve consumer awareness. Risk prevention awareness. In short, even in a "decentralized" business system, centralized departments are needed to provide normative and guarantee support.
Second, regulatory authorities must be prepared to respond to possible changes in regulatory methods. At present, new technologies have a profound impact on the monetary systems of various countries, and the traditional policy framework and means of regulating economic and financial affairs are increasingly unable to keep up with the changes in the situation. Regulatory authorities should keep pace with the times and make full use of the convenience of financial technology to improve supervision methods and improve supervision methods. For example, if securities lending, repurchases, and margin trading can all be traded through a transparent and open blockchain in the future, then regulatory authorities can consider using this public ledger information to monitor systemic risks in the market, which is not only efficient but also reliable.
Third, regulatory agencies can proactively embrace new technologies in Internet finance. Central banks can respond in two ways to a financial landscape transformed by technology: monitor and respond to developments or take a proactive approach. U.S. Securities and Exchange Commission member Kara Stein believes that regulatory agencies need to be in a leading position to take advantage of the advantages of blockchain technology and respond quickly to its potential weaknesses. The Bank of England's research further stated that the central bank may consider issuing blockchain-based digital currencies in the future, which if done properly can increase financial stability.

Blockchain was first launched and recognized by people to support the formation and circulation of Bitcoin. However, unlike the controversial Bitcoin, the introduction of blockchain technology has adapted to the development of the Internet. After entering a new era of mobile Internet, Internet of Everything, and anytime Internet, a large number of online transactions are in urgent need of party identity verification and transaction confirmation. , greatly improve the efficiency of transaction settlement and clearing, and ensure the urgent needs of fund and information security. Therefore, blockchain technologyIt has received increasing attention and attention, and attracted more and more people to explore, innovate and apply.
By the end of 2015, more than 20 of the world's top financial institutions have begun to explore the application of blockchain technology at the financial level. More and more people believe that blockchain technology uses new encryption authentication technology and decentralized mechanisms to maintain a complete distributed, non-tamperable, continuous ledger database, which allows participants in the blockchain to The security of funds and information is ensured through a unified ledger system without the need for mutual recognition and trust. This is of extremely great significance to financial institutions and financial innovation.
First, blockchain technology can reduce trust risks.
Blockchain technology is open source and transparent, and system participants can know the operating rules of the system. Under blockchain technology, since each data node can verify the authenticity and integrity of the ledger content and ledger construction history, it ensures that the transaction history is reliable and has not been tampered with, which is equivalent to improving the accountability of the system. , reducing the trust risk of the system.

Second, from an enterprise perspective, Bubi blockchain has been used in equity, supply chain, points and other fields, and is conducting trials and application tests with exchanges and banks. Bubi Blockchain focuses on the innovation of blockchain technology and products. It already possesses a number of core technologies and has developed its own blockchain service platform. And many blockchain innovative and entrepreneurial companies are constantly emerging.

Third, blockchain can drive the birth of new business models.
The characteristics of blockchain technology enable it to realize some business models that are difficult to achieve in a centralized model. For example, in the Internet of Things industry, some organizations have proposed using blockchain technology to manage the identity, payment and maintenance tasks of tens of billions of Internet of Things devices. Using blockchain technology, IoT device manufacturers can greatly extend the life cycle of products and reduce the cost of IoT maintenance.
Fourth, blockchain technology has a flexible architecture.
Based on different application scenarios and user needs, blockchain technology can be divided into several types: public chain, private chain and alliance chain, which can be selected according to the actual use of the organization.
Fifth, blockchain technology is a beneficial tool for realizing shared finance.
The essence of shared finance is to achieve the purpose of optimizing the allocation of financial resources by reducing the asymmetry of financial information, and through strict third-party certification and supervision mechanisms to ensure the implementation of the rights and interests of both parties to the transaction and facilitate the completion of the transaction. By using blockchain technology, financial information and financial value can be more strictly protected, enabling more efficient and lower-cost flows, thereby realizing the sharing of value and information.
Sixth, the openness of blockchain technology encourages innovation and collaboration.
Through the openness and collaboration of source code, blockchain technology can promote collaboration among different developers, researchers, and institutions and learn from each other's strengths to achieve more efficient and safer solutions.. In recent years, many overseas financial institutions and commercial institutions have tried to use blockchain technology to improve business models. In China, although this technology has not yet been widely recognized and applied, it has begun to attract more and more widespread attention. Attention, its influence is rapidly increasing. Now blockchain technology has been regarded as one of the basic protocols for the next generation of global credit certification and value Internet. The importance of blockchain technology to my country's financial industry and financial system cannot be ignored.
Of course, we must know that the development of blockchain technology is still in its early stages globally, and various technical solutions, application scenarios and business models need to be further explored and improved. Especially in our country, blockchain is a brand-new concept and theory, and people's cognition, research and practice have just begun. If we want to overtake in this field, catch up with the advanced, and lead the world, we still need enough attention. More investment requires the active investment and positive interaction of theoretical researchers, network technicians, financial practitioners, and regulatory authorities, and the courage to explore and innovate.

What is blockchain technology? People will definitely understand more and more about such technology, and it will play an increasingly important role in reality, and will be supported by many institutions, thus bringing the popularization of blockchain into a new application stage in reality.

4. What are the application fields of blockchain technology?

Application fields: financial field, Internet of Things and logistics field, public service field, digital copyright field, insurance field, and public welfare field.

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.

Blockchain is closely related to people’s production and life in the fields of public management, energy, transportation, etc. However, the centralized nature of these fields also brings some problems, which can be transformed with blockchain.

5. How to apply blockchain How to apply blockchain

1. Financial field: < br>Blockchain has potential huge application value in financial fields such as international exchange, letters of credit, equity registration and stock exchanges. 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 completing transactions quickly.Easy to pay.
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. However, the centralized nature of these fields also brings some problems. Blockchain can be used chain to transform. 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.

6. What are the applications of blockchain in the industry?

Take the tourism industry as an example. Blockchain applications are mainly concentrated in travel, travel community reviews, digital identity management, and credit consumption management. , tracking pilot professional certificates and qualifications, hotel and airline loyalty programs, reservation management, consumption points managementthese 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.

7. 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. 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 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, 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 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. Of course, there are some that are really reliable, which requires everyone to be careful.discerned.

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, 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 during the real-time solidification process. 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 blockpractical performance of chain 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 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 an article titled "JIn the paper "Asper Project: 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 require publicity to a certain extent. and observability.”

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 It will soon be released 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 pointed out that “many governments will award project contracts to a certain supplier in the absence of fair competition. This makes companies with more political resourcesUnfairly beating competitors; or companies in the same industry negotiating bids in advance to ensure each company gets a share of the tender pie. 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 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 is a method that provides reliable and trustworthy organizational data for cross-subject business scenarios.part. 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 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 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.

What can the blockchain do?

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 collect the data of low-income policyholders, in today’s Internet, data is value and wealth.Therefore, value protection and value transmission are the future development directions of the Internet, and blockchain technology can truly achieve this.

If there are any deficiencies, you are welcome to comment and correct me.

In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-transformable. 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. . 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 15,728.64 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.

8. In which fields is blockchain suitable for application?

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 and high-speed computing, safety, convenience and other characteristics have laid a strong foundation for the advancement and popularization of technology.

9. What are the fields involved in blockchain applications, and what are the specific scenarios?

Blockchain technology is widely used, and with the integration of new technologies, the main The application scenarios cover many fields such as finance and insurance, intelligent manufacturing, intelligent environmental protection, energy and electricity, medical and health care, education, cultural and creative industries, smart cities, social welfare, agriculture and many other fields.
