A. What are the classifications and applications of blockchain projects

From the current mainstream blockchain projects, blockchain projects mainly fall into four categories: First Category: Currency; Category 2: Platform Category; Category 3: Application Category; Category 4: Asset Tokenization.

Coins mainly serve as the "medium of exchange" in the field of blockchain assets. The medium of exchange refers to general equivalents, such as gold and silver notes in the past. (Trade blockchain assets on "Bihui Exchange")

Platform projects refer to the establishment of technology platforms to meet the development of various blockchain applications, which can reduce the cost of developing applications on the blockchain. threshold.

The scope of application projects is relatively wide, covering many fields such as finance, social networking, games, property rights protection, etc. It is also the fastest growing field of blockchain assets at present.

The asset tokenization project refers to the blockchain mapping of physical assets, that is, the physical assets are put on the chain. Currently, there are no more than 10 varieties.

01 Currency

The first category is currency projects, which are also the earliest blockchain projects. Currency projects mainly include projects such as Bitcoin and Litecoin. In addition, there is another type of asset that has the characteristics of anonymity. Its main functions include realizing payment while protecting the privacy of both parties. The well-known ones include Dash, Monero and Big Zero that use zero-knowledge proof. Coin (Zcash), etc. Currency mainly serves as the "medium of exchange" in the blockchain asset field. The medium of exchange is the general equivalent that you use to exchange for goods. For example, in the past, gold, silver, and banknotes could be used as media of exchange. There are currently more than 2,100 types of digital assets in the world, and the number of currency blockchain projects has grown rapidly recently. As of June 2018, Bitcoin still has the largest market value.

02 Platform Category

The second category is platform blockchain projects. The main function of platform blockchain projects is to establish a technology platform to meet the needs of various blockchain application development. The required technical requirements; simply put, platform applications allow developers to directly issue digital assets on the blockchain, write smart contracts, etc. A smart contract is a computer program that runs on a blockchain database and can be automatically executed under conditions set by its source code.

For example, if you develop a smart contract based on a house rental agreement on the blockchain, when the owner receives the rent, it will trigger automatic execution and give the apartment's security key to the tenant.

The main function of platform blockchain projects is to establish an underlying technology platform to allow developers to develop applications on the underlying technology platform. A considerable number of platforms are still under development. As of June 2018 , the one with the largest market value is Ethereum.

03 Application Category

The third category is application blockchain projects. Application projects are developed based on blockchain development platforms (such as Ethereum) and can solve various problems in the real economy. Blockchain projects that address many issues in the field.

For example, the blockchain-based prediction platform Augur, based on the blockchainGolem, a computing power trading platform, VeChain, a luxury goods traceability platform based on blockchain, and OmiseGo, which provides asset exchange and transfer services based on blockchain. Using blockchain technology, these projects can better solve trust issues, cross-border circulation and other issues. At the same time, using smart contracts and tokens on the blockchain, automatic execution can be better realized, greatly improving the efficiency of social and economic activities. efficiency. The scope of applied blockchain projects is relatively wide, covering many fields such as finance, social networking, games, property rights protection, etc. It is also the field where the market value of blockchain projects is increasing the fastest.

04 Asset Tokenization

The fourth category is asset tokenization blockchain projects. Asset tokenization refers to linking blockchain assets to physical assets such as gold and U.S. dollars. , is a blockchain mapping of physical assets. As of February 2018, there are no more than 10 varieties. The more typical representatives are USDT, which is benchmarked against the US dollar, and Digix Dao, which is benchmarked against gold. Each DigixDAO token represents 1 gram of London gold. Silver Market Association certified gold. Asset tokenization has the advantages of convenient transactions and safekeeping. First, asset tokenization makes transactions easier. Because blockchain assets can be split, they have better liquidity.

For example, currently the real estate needs to be transferred as a whole. If the real estate can be tokenized, it can be purchased in pieces, making transactions more convenient. Secondly, tokenization of physical assets is more conducive to safekeeping. In physical transactions such as gold, it is easy to cause wear and tear and cause losses. However, after tokenization of physical assets, there is no need for physical transfer, which is more conducive to the custody of physical assets.

D. In what fields is the blockchain suitable for application?

There are many applicable fields for the blockchain. Just like when the Internet just started, some people would ask which fields the Internet is suitable for. In the future it will apply to every aspect of our lives. Now we have seen applications in medical, education, aviation, finance, social networking, games and other fields.

E. Blockchain applications include

Blockchain applications include:

(1) Blockchain + Medical: 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 IoT of blockchain technology Networked applications will 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 the core of market competition.elements. 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 has the characteristics of disintermediation, consensus mechanism, and non-tampering. Using blockchain technology, it can effectively integrate all aspects of the cultural and entertainment value chain, accelerate circulation, and shorten the value creation cycle; at the same time , can realize the value transfer of digital content, ensure the credibility, auditability and transparency of the transfer process, and effectively prevent 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. Traditional The method is to rely on a credible third party for credit endorsement, but problems such as fraud and deficiencies still exist. 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.

F. What are the applications of blockchain

Briefly introduce the application of blockchain technology in the financial field

1. The application of blockchain technology in the banking industry

The biggest feature of blockchain technology is decentralization, and this feature will reduce a lot of costs for the banking industry.

First of all, decentralization means that the establishment of a trust mechanism between banking systems no longer requires an intermediary, saving intermediary costs.

Secondly, the development of digital currency will make it possible to realize real-time digital transactions in banks. For example, in bill transactions, bank bill transactions have always relied on a third party to realize the transfer of valuable certificates. Even electronic bill transactions require interactive authentication through information from the central bank's ECDS system. Blockchain technology can realize point-to-point transfer of value and no longer requires centralized system control. This not only speeds up the speed of ticket transfer, but more importantly, it can reduce errors caused by human factors and reduce processes. Naturally, it will reduce the bank's demand for personnel and save the bank's labor costs.

Finally, it will also have an impact on clearing and settlement. The bank's clearing and settlement business has always been completed by central clearing, which is inefficient. Settlement through blockchain technology will greatly improve the efficiency of banks.

Blockchain technology also plays a major role in banks’ cross-border payment services. Today, when global trade is highly developed, cross-border payments are becoming more and more frequent, and banks often act as third-party services in cross-border trade, such as electronic transfers, asset custody, etc. However, cross-border payments generally take about 2 days to arrive, which is very inefficient and reduces the utilization of funds in transit. In blockchain technology, both parties of cross-border payments can be completed in a point-to-point manner, achieving round-the-clock payment and real-time arrival, thereby speeding up clearing and settlement, thereby improving the efficiency of bank processing business.

Another characteristic of blockchain technology is thatTo de-risk, banks can build their own blockchain, which can ensure that the transaction information and transaction records of bank customers are true and valid and will not be arbitrarily tampered with. Banks can effectively identify customer information and understand their customers. Various aspects of the situation can be used to identify abnormal transactions of customers to prevent being deceived by customers. It can also promptly detect criminal activities such as illegal money laundering and transfer of funds, thereby reducing the bank's supervision costs.

2. Application of blockchain technology in the insurance industry

Blockchain technology also has incomparable advantages in the insurance industry. From the perspective of data management, the application of blockchain technology by insurance companies can effectively improve risk management and control capabilities, including the risk supervision of insurance companies and the risk management of policyholders.

The application of blockchain technology in the insurance industry can strengthen the internal risk supervision of insurance companies. Blockchain technology can record the daily operating processes of insurance companies on nodes, and can achieve in-process control over the company's capital flow, investment status, compensation payments and other businesses, and improve the company's risk management and control capabilities.

In addition, blockchain technology is safe, reliable, and cannot be tampered with at will, ensuring that the information obtained by the policy holder is true and effective, thereby enhancing the policy holder's risk management capabilities.

3. Application of blockchain technology in the securities industry

The application of blockchain technology in the securities industry can increase the flexibility of securities issuance. Companies issuing securities can use smart contracts , by setting the method and time of securities issuance, securities can even be issued 24 hours a day under the most ideal condition.

Under the operation of smart contracts, automatic matching of buyers and sellers is realized, and settlement and clearing steps are automatically completed through the distributed digital registration system. The transaction records on the blockchain will not be changed arbitrarily, so the entered information actually has a publicity effect, so there will be no dispute in the stock exchange's ownership confirmation.

In addition, blockchain technology makes the securities trading process more open and transparent. Through blockchain technology, the securities industry does not need a central organization to operate and manage, nor does it require investment banks to underwrite, to achieve true peer-to-peer transactions, reduce illegal activities such as black-box operations and insider trading in securities transactions, and realize the control of securities. Effective supervision of the industry.

4. Blockchain technology and financial infrastructure

Blockchain technology uses a decentralized mechanism to exchange value, which will lead to a modern world characterized by centralization. Some financial infrastructures have undergone earth-shaking changes.

Assets such as collateral, pledges, stocks, bonds, and derivatives usually require a trustworthy central organization to register or keep them, but blockchain can record and save these in a new way. Product data will have an impact on the registration system for these products.

The blockchain can receive and react to information and value through smart contracts, automatically complete the transfer of value, and automatically complete transactions, clearing and settlement, which will impactExisting financial infrastructure such as large-value trading systems, central securities depositories, securities settlement and over-the-counter derivatives trading.

5. Application of blockchain technology in supply chain

The application of blockchain technology in supply chain first provides credit guarantee, and the blockchain records Commodity circulation information, etc., can prove the authenticity and reliability of commodities and their circulation, thereby enabling a comprehensive evaluation of the utility of enterprises on the chain, and becoming an effective guarantee for corporate bank loan credit, financing credit, and transaction credit. .

First of all, the blockchain can time-stamp all the transaction data in the supply chain and cannot be tampered with at will. Even if the transaction data of a certain node can be tampered with, it cannot cover the sky with one hand, so the area Blockchain solves banks' concerns about corporate information being tampered with. For some small businesses, as long as they have good credit, the possibility of borrowing from banks will be greatly increased.

Secondly, through effective integration, the information between upstream and downstream enterprises recorded in the blockchain can not only provide support for enterprises in production, sales and other links, but also provide downstream enterprises with the ability to analyze customer preferences. , so that targeted services can be developed.

G. What is blockchain technology and what areas may it be used in the future

What is blockchain technology? Blockchain is a distributed shared accounting technology that allows all parties involved to establish a trust relationship at the technical level. Blockchain can be roughly divided into two levels: one is the underlying technology of the blockchain; the other is the upper-layer application of the blockchain, that is, the transformation, optimization or innovative application based on the blockchain.
Blockchain has been applied in several fields. In the first field of digital assets, in addition to some points and check-in cards we have seen, it also includes various other assets, and there is a process of asset digitization.
The second area is the field of trade finance. Because the field of trade finance is originally a multi-link and multi-party participation method, blockchain can greatly improve the efficiency of the middle, making many of the original substitutes effective.
The third area uses equity, which is a company's equity like some regional equity trading centers. The purpose is to facilitate equity-to-transactions and facilitate relative circulation. At present, the multi-center blockchain system can indeed improve efficiency and reduce costs.
Xinlian is an information platform for news and data mining that is vertical in the field of blockchain. We hope it will be helpful to you.

H. In what fields is blockchain applied?

The benefits brought by Bitcoin and blockchain technology in the economic, political, humanitarian and legal systems clearly show that it It has the potential to become a disruptive innovative technology that can reshape all aspects of society and the way it operates. If the applications of blockchain are divided into 1.0, 2.0, and 3.0. Blockchain 1.0 is currency, and its applications are related to cash, such as currency transfer, exchange and payment systems. Blockchain 2.0 is a contract, such as stocks, bonds, futures, loans, mortgages, property rights, intellectual property, etc.Energy assets and smart contracts. Blockchain 3.0 is an application beyond currency, finance, and markets, especially in the fields of government, health, science, literature, culture, and art. In the end, blockchain technology will organically combine big data and artificial intelligence, allowing the entire Internet era to leap into the next era of more precise connections.

I. Applications of Blockchain

The main application scope of Blockchain includes: digital currency, transaction settlement of financial assets, 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 a distributed shared 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, data integrity protection, and effective prevention of DDoS attacks

The distributed storage architecture of the blockchain will make hackers at a loss. Some companies have begun to develop a distributed Internet domain name system based on the 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.

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 say, thisThis 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 easier. Emerging blockchain 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 achieve this through blockchain. Equity transfer of private companies

8. Government management

Government information, project bidding and other information are open and transparent. Government work is usually subject to public attention and supervision, because blockchain technology can ensure the transparency and immutability of information. , which plays a great role in the implementation of transparent government management. There is a certain degree of information opacity in government project bidding, and companies also have the risk of information leakage during the sealed bidding process. Blockchain can ensure that bidding information cannot be tampered with, and can ensure the transparency of 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 in various places

J. What are the main application scopes of blockchain

What are the main application scopes of blockchain? : Digital currency, transaction settlement of financial assets, digital government affairs, supply chain field, automobile industry, public service field, information security field, certificate storage and anti-counterfeiting data services and other fields. Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. It is an important concept of Bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each data block contains The information of a batch of Bitcoin network transactions is used to verify the validity of its information (anti-counterfeiting) and generate the next block.
