1. 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. Application areas include consumption management, tracking pilots’ professional certificates and qualifications, hotel and airline loyalty programs, reservation management, and consumption points management. 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.

2. In what fields can blockchain be applied?

Financial applications: Blockchain has inherent advantages in the financial field. On the Internet, this is the gene of blockchain. decided.
(1) Insurance business: With the development of blockchain technology, in the future, personal health status, accident records and other information may be uploaded to the blockchain, allowing insurance companies to be more timely and accurate when customers apply for insurance. Accurately obtain risk information to reduce underwriting costs and improve efficiency. The shared and transparent characteristics of the blockchain reduce information asymmetry and the risk of adverse selection; while its historical traceability characteristics are conducive to reducing moral hazard, thereby reducing the difficulty and cost of insurance management.
(2) Asset securitization: The pain point of business in this field is that the authenticity of the underlying assets cannot be guaranteed; there are many participating entities, many operating links, low transaction transparency, and information asymmetry, making it difficult to control risks. The pain point of data lies in the low efficiency of transfers between participants, the clearing and reconciliation of funds between parties’ trading systems often requires a lot of manpower and material resources, and there are multiple online and offline channels for asset repayment, making it impossible to monitor the true status of assets, and there are still assets After the package is formed, the trust of all parties in the transaction chain in the authenticity and accuracy of the underlying asset data is an issue.
(3) Digital bills: The pain points in this field lie in three risk issues. Operational risk, due to the centralization of the system, once the central server has a problem, the entire market will be paralyzed; market risk, according to statistics, in 2016, there were seven risk events involving hundreds of millions of dollars, involving multiple banks; moral hazard , there are incidents such as "one ticket selling more" and false commercial bills in the market. Blockchain's disintermediation, system stability, consensus mechanism, and non-tampering characteristics reduce operational risks, market risks, and moral hazards in traditional centralized systems (4) Cross-border payments: The pain point in this field is the long payment cycle , high fees and low transaction transparency. The third-party payment company is the center to complete the accounting, settlement and liquidation in the payment process, and the payment cycle is long. For example, the payment cycle for cross-border payments is more than three days, and the cost is high. The blockchain is deintermediated, the transactions are open, transparent and cannot be tampered with. There is no third-party payment institution to join, which shortens the payment cycle, reduces fees and increases transaction transparency.
(5) Credit information management: The pain points in this field are the lack of data sharing and the asymmetry of information between credit information agencies and users; formal market-oriented data collection channelsLimited, the battle for data sources consumes a lot of costs; data privacy protection issues are prominent, and traditional technical architecture is difficult to meet new requirements. In the field of credit reporting, blockchain has the characteristics of decentralization, trustlessness, timestamps, asymmetric encryption and smart contracts. At the technical level, it ensures that limited and controllable credit can be achieved on the basis of effectively protecting data privacy. Data sharing and verification.
(6) Supply chain finance: The pain points in this field are the long financing cycle and high costs. Centered on the core enterprise system of the supply chain, it is difficult for third-party credit enhancement institutions to authenticate the authenticity of various relevant vouchers in the supply chain, resulting in long manual review times and high financing costs. The blockchain's deintermediation, consensus mechanism, and non-tampering characteristics eliminate the need for third-party credit enhancement agencies to verify the authenticity of various relevant certificates in the supply chain, reducing financing costs and shortening the financing cycle.
(7) Asset securitization: The business pain point in this field lies in the fact that the authenticity of the underlying assets cannot be guaranteed; there are many participating entities, multiple operating links, low transaction transparency, and information asymmetry, making it difficult to control risks. The pain point of data lies in the low efficiency of transfers between participants, the clearing and reconciliation of funds between parties’ trading systems often requires a lot of manpower and material resources, and there are multiple online and offline channels for asset repayment, making it impossible to monitor the true status of assets, and there are still assets After the package is formed, the trust of all parties in the transaction chain in the authenticity and accuracy of the underlying asset data is an issue. Blockchain's deintermediation, consensus mechanism, and non-tampering characteristics increase data flow efficiency, reduce costs, monitor the true status of assets in real time, and ensure the trust of all parties in the transaction chain in the underlying assets.
Applications:
(1) Blockchain + Medical: In the medical field, blockchain can use its anonymity, decentralization and other characteristics to protect patient privacy. Electronic health records (EHR), DNA wallets, drug anti-counterfeiting, etc. are all possible application areas of blockchain technology. IBM predicted in last year's report that 56% of medical institutions around the world will invest in blockchain technology by 2020.
(2) Blockchain + Internet of Things: The Internet of Things is a very broad concept. If communications, energy management, supply chain management, sharing economy, etc. are included, the Internet of Things application of blockchain technology will has become a very important application field.
(3) Blockchain + IP Copyright & Culture and Entertainment: The Internet is developing better and better, and digital music, digital books, digital videos, digital games, etc. have gradually become mainstream. The rise of the knowledge economy has made intellectual property rights a core element of market competition. However, intellectual property infringement is serious in the current Internet ecosystem, and the copyright protection of digital assets has become a pain point in the industry. Blockchain features disintermediation, consensus mechanism, and non-tampering. Blockchain technology can effectively integrate all aspects of the cultural and entertainment value chain, accelerate circulation, and shorten the value creation cycle; at the same time, the value of digital content can be realized Transfer, and ensure that the transfer process is credible, auditable and transparent, effectively preventing piracy and other behaviors.
(4) Blockchain + Public Services& Education: In the fields of public services, education, charity and public welfare, issues such as file management, identity (qualification) certification, and public trust all exist objectively. The traditional method is to rely on a credible third party for credit endorsement, but fraud and lack of The problem still exists. Blockchain technology can ensure the integrity, permanence and unchangeability of all data, and thus can effectively solve the difficulties and pain points in these industries in terms of certificate storage, tracking, association, and backtracking.

3. How blockchain is used in industries

Blockchain can be applied to many industries and can bring great changes to the industry.
1. Payment and cash transactions
Blockchain uses its decentralized advantage to create a more direct payment flow for payments and cash transactions. It can be domestic or cross-border and does not require intermediaries. Super low rates and almost instantaneous speeds for payment.
2. Banking Industry
Essentially, a bank is a secure storage warehouse and value exchange center, and blockchain, as a digital, secure and tamper-proof general ledger, can achieve the same effect.
3. Games
The core value of the blockchain application game field: returning game rights to game players. The technical features of blockchain technology such as decentralization, smart contracts, and asset transactions can well solve the problem of privacy leakage of game data and user data in the current gaming industry, promote the preservation of the value of virtual digital currencies in games, and realize the development of users and games. Fair value sharing through channels.
4. Internet of Things
As an anonymous and decentralized peer-to-peer remote sensing technology, blockchain can become a public account book for a large number of devices, and they will no longer need to have a centralized routing between them. Intermediate traffic. Without a central control system to authenticate, devices will be able to anonymously transmit between themselves and manage software updates, errors, or energy management.
5. Supply chain finance
Blockchain can alleviate the problem of information asymmetry and is very suitable for the development of supply chain finance. In the supply chain, goods are accompanied by monetary payment activities from sellers to buyers. In the context of high credit costs and corporate cash flow needs, financial services companies provide goods transfer and payment protection. The characteristics of supply chain traceability, anti-counterfeiting, transaction authenticity, and timely liquidation will solve many pain points in the existing trade finance network and shape the infrastructure of the next generation of supply chain finance.
6. Copyright protection
In the blockchain technology environment, every copyright transaction will produce an irreversible transaction record, which means that it includes an idea, story, script or character. Once recorded on the blockchain, the asset will always be tracked even if ownership is exchanged, transferred, sold, etc., thus solving copyright issues.
7. Cross-border payment
Cross-border payment involves multiple currencies, has exchange rate issues, cumbersome processes, and long settlement cycles: traditional cross-border payments are basically non-real-time, and banks conduct transactions in batches at the end of the day. deal with, usually a lump sumTransactions take more than 24 hours to complete; some banks' cross-border payments appear to be real-time, but in fact, the receiving bank advances a certain amount based on the credit of the remitting bank, and then performs fund settlement and reconciliation at the end of the day. Account, business processing speed is slow.
8. Cloud Computing
The core value of blockchain application in the field of cloud computing: Promote the construction process of public trust infrastructure.
The my country Academy of Information and Communications Technology believes that the combination of blockchain and cloud is also an inevitable trend. There are two ways to combine blockchain and cloud, one is blockchain on the cloud, and the other is blockchain in the cloud.
9. File Storage
The decentralization of blockchain can store data in a safe, high-performance and cheap way, spreading the data across many nodes. As for data security, the blockchain approach means that each file is shredded and encrypted using your own key, then spread across the network until you are ready to use the file again and need to retrieve it. , the files are decrypted and quickly and seamlessly reassembled.
There are too many usage scenarios for blockchain. Here are just some of them. More industries can read related books.

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.

8. Applications of blockchain

The main application scope of blockchain includes: digital currency, financial asset transaction settlement, digital government affairs, certificate deposit and anti-counterfeiting data services and other fields . Blockchain is a database technology that links data blocks in an orderly manner. Each block is responsible for recording a file data and encrypting it to ensure that the data cannot be modified or forged.

Blockchain is essentially a distributed database system that uses cryptography technology for multi-party participation, joint maintenance, and continuous growth. It is also called distributed sharing.Ledger. Each page in the shared ledger is a block, and each block is filled with transaction records. The anonymity, decentralization, openness, transparency, and non-tamperability of blockchain technology make it highly favored by enterprises and has gained More extensive application attempts.

Blockchain application scope 1. Financial field

Blockchain can provide a trust mechanism and has the potential to change the financial infrastructure. Various financial assets such as equity, bonds, bills, warehouse receipts, fund shares, etc. It can be integrated into the blockchain technology system and become a digital asset on the chain, which can be stored, transferred and traded on the blockchain.

The decentralization of blockchain technology can reduce transaction costs and make financial transactions more convenient, intuitive and secure. The combination of blockchain technology and the financial industry will inevitably create more and more business models, service scenarios, business processes and financial products, thereby bringing more impact to the development of financial markets, financial institutions, financial services and financial formats. . With the improvement of blockchain technology and the combination of blockchain technology with other financial technologies, blockchain technology will gradually adapt to the application of large-scale financial scenarios.

2. Public service field

Traditional public services rely on limited data dimensions, and the information obtained may not be comprehensive enough and have a certain lag. The non-tamperable nature of the blockchain makes the digital certification on the chain highly credible. It can be used to establish new authentication mechanisms in the fields of property rights, notarization and public welfare, and improve the management level of public services.

Relevant information in the public welfare process, such as donation projects, fundraising details, fund flows, recipient feedback, etc., can be stored on the blockchain to meet the privacy protection of project participants and other relevant laws and regulations. Under the premise of requirements, public disclosure will be made conditionally to facilitate public and social supervision.

3. Information security field

Using the traceability and non-tampering characteristics of blockchain, we can ensure the authenticity of data sources and ensure the non-forgery of data. Blockchain technology will fundamentally change information Security issues of the propagation path.

Blockchain is reflected in the following three points in the field of information security:

User identity authentication protects data integrity and effectively prevents DDoS attacks

The distributed storage architecture of blockchain will make Hackers are at a loss as to what to do. Some companies have begun to develop a distributed Internet domain name system based on blockchain to eliminate the root cause of the current DNS registration shortcomings and make the network system cleaner and more transparent.

4. Internet of Things field

Blockchain + Internet of Things can allow each device on the Internet of Things to operate independently, and the information generated by the entire network can be protected through smart contracts in the blockchain.

Security: Traditional IoT devices are highly vulnerable to attacks, data loss and maintenance costs are high. Typical information security risk issues for IoT devices include low firmware versions, lack of security patches, permission loopholes, too many device network ports, and unencrypted information transmission. The blockchain's consensus mechanism for network-wide node verification, asymmetric encryption technology and distributed data storage will significantly reduce the risk of hacker attacks.risk.

Trustability: The traditional Internet of Things is managed and controlled by a centralized cloud server. Due to the security of the device and the opacity of the centralized server, it is difficult to effectively protect user privacy data. The blockchain is a distributed account book. Each block is interconnected and has its own independent working ability, ensuring that the information on the chain will not be tampered with at will. Distributed ledgers can therefore provide trust, ownership records, transparency and communication support for the Internet of Things.

Effectiveness: Limited by cloud services and maintenance costs, the Internet of Things is difficult to achieve large-scale commercial use. The traditional Internet of Things realizes communication between things through centralized cloud servers. The disadvantage of this model is that as the number of access devices increases, the server faces more load, requiring enterprises to invest a lot of money to maintain the normal operation of the IoT system.

Blockchain technology can directly realize point-to-point transactions, omitting the labor expenditure of other intermediaries or personnel, which can effectively reduce the costs incurred by third-party services and maximize benefits.

5. Supply chain field

The supply chain consists of many participating entities, with a large amount of interaction and collaboration. Information is discretely stored in their own systems, lacking transparency. The lack of smooth information makes it difficult for various participating entities to accurately understand the real-time status and existing problems of related matters, affecting the collaborative efficiency of the supply chain. When disputes arise between parties, it is time-consuming and laborious to provide evidence and pursue accountability.

Blockchain can make data open and transparent among various entities, thereby forming a complete, smooth, and non-tamperable information flow throughout the entire supply chain. This can ensure that all entities promptly discover problems arising during the operation of the supply chain system and find targeted solutions, thus improving the overall efficiency of supply chain management.

6. Automotive Industry

Last year announced a partnership using blockchain to build a proof of concept to streamline the car rental process and build it into a “click, sign up, and drive” process. Future customers choose what they want The rented car enters the public ledger of the blockchain; then, sitting in the driver's seat, the customer signs the rental agreement and insurance policy, and the blockchain updates the information simultaneously. This is not an imagination, for car sales and car registration Said, this type of process may also develop into reality.

7. Stock Trading

For many years, many companies have worked to make the process of buying, selling, and trading stocks easy. Emerging Blockchain Chain startups believe that blockchain technology can make this process more secure and automated than any previous solution. At the same time, blockchain startup Chain is working with Nasdaq to enable private companies through blockchain. Equity transfer

8. Government management

Government information, project bidding and other information are open and transparent. Government work is usually subject to public attention and supervision. Since blockchain technology can ensure the transparency and immutability of information, it is very important to the government. The implementation of transparent management plays a great role. There is a certain degree of information opacity in government project bidding, and enterprises also have the risk of information leakage during the sealed bidding process. Blockchain can ensure that bidding information isThe information cannot be tampered with and can ensure the transparency of the information, forming a shared trust among competitors who do not trust each other. And it can arrange subsequent smart contracts through the blockchain to ensure the construction progress of the project and prevent the growth of corruption to a certain extent.

There are many more applications of blockchain technology, and this is just a fulcrum of blockchain applications. In the future, blockchain technology will be applied everywhere
