⑴ What should the phenomenon and application of blockchain look like

1. The revolution of blockchain

Until the 7th year after the emergence of Bitcoin In this year, its underlying core technology blockchain has only begun to become known to people. With the wealth effect caused by Bitcoin’s multi-million-fold increase, blockchain is becoming more and more popular. Its value is widely recognized and it is generally considered to be the core technology leading the fourth industrial revolution.

In 2018, Xu Xiaoping, a well-known angel investor, raised his arms and shouted: "The blockchain revolution has arrived! We must embrace this revolution!" With one stone, it caused thousands of waves, and soon the official blockchain learning book was launched online , official media interpreted that a wave of entrepreneurship and recruitment are coming one after another. In 2019, blockchain was officially designated as “an important breakthrough for independent innovation in core technology.”

Under this situation, blockchain has become an out-and-out "new trend", and blockchain application has become a keyword. It has significant advantages in optimizing business processes and building trustworthy systems. How can we use these advantages of blockchain technology to empower the real economy?

Not only blockchain project parties are trying, but also Chinese Internet companies represented by BAT, financial systems and mobile operators represented by China Merchants Bank, Bank of China, and Ping An Insurance, etc. They are all actively carrying out "blockchain+", and it is also in full swing overseas. Facebook, Goldman Sachs, JPMorgan Chase, etc. are all actively promoting it.

2. Blockchain+

On August 10, 2018, Tencent issued the first blockchain electronic invoice. As of July 3, 2020, invoices were issued Volume reaches 25 million. Blockchain electronic invoices have the advantages of simple invoicing, on-demand supply, low cost, high efficiency, and anti-counterfeiting. Tencent Blockchain quickly occupied the market with first-mover advantages in blockchain + government affairs and blockchain + taxation.

Ant Financial, owned by Alibaba, began to deploy blockchain as early as 2015. So far, Ant Blockchain has open alliance chain, BaaS platform and other products covering dozens of application scenarios. It has reached on-chain cooperation with many well-known global companies such as Intel, Jingdezhen Porcelain, and Bayer. The Internet also entered the blockchain very early and launched blockchain games, blockchain certificate storage and other services. Currently, the number of certificates stored on the chain has exceeded 100 million.

In 2019, the scale of China's blockchain industry alone reached 1.2 billion yuan. Data from the research institution Research and Markets shows that the output value of blockchain technology in the telecommunications field will surge from 4.66 million US dollars in 2018 to 2023. 993.8 billion US dollars in the year. Against this background, 2020 will usher in multiple policy benefits.

1. Officials include blockchain in the scope of new infrastructure and new technology infrastructure;

2. Released by Hunan"Three-year Action Plan for the Development of the Blockchain Industry in Hunan Province (2020-2022)";

3. Guangzhou launched the "Implementation Opinions of Guangzhou City on Promoting the Innovation and Development of the Blockchain Industry (2020-2022)" )";

4. Beijing issued the "Beijing Blockchain Innovation Development Action Plan (2020-2022)";

5. Jiangxi launched blockchain services online Hall;

6. Wuhan holds a special event for the transformation of blockchain technology and scientific and technological achievements;

7. Chongqing Smart Expo Blockchain Application Innovation Competition plans to invest a huge investment of 50 million yuan as investment incentives.

However, although the implementation of blockchain in financial, government affairs, charity, games, agriculture, manufacturing, medical care, copyright and other physical fields has achieved remarkable results, it has also played an active role in fighting the new crown epidemic. role.

However, due to the influence of the general environment, more funds, resources, and attention have been attracted to the direction of blockchain empowering the real economy, but the core native applications of blockchain have been ignored.

3. Blockchain native applications

The Internet has opened an era of information explosion, and blockchain will bring a future where value flows freely. In today's global economic and financial system, affected by many factors such as ideology, cultural systems, business models, and technological levels, the cost of value transfer is high and the efficiency is low, especially in cross-border payment scenarios.

In the future blockchain era, value transfer will be like information transfer: global, instant, free, and equally enjoyed by everyone. All offline assets such as stocks, securities, identities, and real estate can be freely converted on the chain.

Moreover, the impact of blockchain technology has far exceeded the technical category itself. It is also an idea. The soul of blockchain lies in consensus. In the era of blockchain, truly powerful vitality will be born in community consensus and application implementation, and community and consensus will become the main body and soul of the industry.

In a community with consensus, individual energy and value will be fully stimulated, offsetting the fission effect of traditional centralization, breaking the original solid underlying structure, and reshaping new business and social values.

Therefore, blockchain native applications should be based on community and consensus, give individuals a path to realize their value, and be able to maximize the application ecosystem that stimulates individual energy and creativity, ultimately breaking monopoly and forming Decentralized free value exchange network.

Individual energy and value are multi-dimensional and highly subjective. These blockchain model designs obviously cannot fully stimulate individual energy, and are even far from it.

True to the blockThe native application of Chain Spirit should be grand and comprehensive in the design of the application model, taking into account all the online and offline value-creating behaviors of individuals, and providing them with personalized use. Each individual's areas of expertise are different.

Borrowing from the Pareto optimal solution theory, each individual's energy can be maximized to maximize the overall energy, break the original centralized business model, and form a free flow of global individuals. A peer-to-peer value transmission network builds a new decentralized business infrastructure, changes the value creation and delivery model, and reshapes the values ​​of the entire society.

⑵ What are the technological innovations and applications of blockchain

1. Blockchain system

As the underlying technology of Bitcoin, the blockchain system generally consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer.

1. Data layer

The data layer encapsulates basic data and basic algorithms such as underlying data blocks and related data encryption and timestamps. It mainly describes the physics of the blockchain. The form is the chain structure on the blockchain starting from the genesis block. It includes the block data and chain structure of the blockchain, as well as the random numbers, timestamps, public and private key data on the blocks, etc. It is the underlying data structure in the entire blockchain technology.

2. Network layer

The network layer mainly implements distributed network mechanisms through P2P technology, including P2P networking mechanisms, data dissemination mechanisms and data verification mechanisms. Therefore, in essence, the blockchain is a P2P network with an automatic networking mechanism, and nodes maintain communication by maintaining a common blockchain structure.

3. Consensus layer

The consensus layer includes consensus algorithms and consensus mechanisms. The consensus layer allows highly dispersed nodes to efficiently reach consensus on the validity of block data in a decentralized blockchain network. It is one of the core technologies of the blockchain and is also the governance mechanism of the blockchain community. There are currently dozens of consensus mechanism algorithms, including proof of work, proof of equity, proof of equity authorization, proof of burning, proof of importance, etc.

4. Incentive layer

The incentive layer mainly includes the issuance system and distribution system of economic incentives. Its function is to provide certain incentives to encourage nodes to participate in the security of the blockchain. Verification work, and incorporating economic factors into the blockchain technology system, incentivizing nodes that abide by the rules to participate in accounting, and punishing nodes that do not abide by the rules.

5. Contract layer

The contract layer mainly includes scripts, codes, algorithm mechanisms and smart contracts, and is the basis for blockchain programmability. It embeds code into the blockchain orIn tokens, customized smart contracts can be implemented. When certain constraints are met, they can be automatically executed without going through a third party, which is the basis for trust in the blockchain.

6. Application layer

The application layer encapsulates various application scenarios and cases, similar to applications on computer operating systems, portals on Internet browsers, search Engine, e-mall or APP on mobile phone. It deploys blockchain technology applications on Ethereum, EOS, QTUM, etc., and implements them in real life scenarios. In the future, programmable finance and programmable society will be built on the application layer.

The data layer, network layer and consensus layer are necessary elements to build blockchain technology. Without any layer, it cannot be called blockchain technology in the true sense; the incentive layer, contract layer and The application layer is not a necessary factor for every blockchain application, and some blockchain applications do not completely include this three-layer structure.

From a business perspective, blockchain technology has its own characteristics, that is, it is sufficiently digital, it is cross-border, cross-time and space, and cross-organization. The flow of data has no boundaries, so the blockchain is distributed at the same time, it is self-organized and decentralized.

So the origin of blockchain and the application of any new disruptive technology have always had two routes, or two methods. One way is to regard it as a tool and use it to improve the traditional business model and obtain an improvement in marginal benefits. The other is to treat it as a system to reconstruct the underlying logic of business.

There is a good example of these two application methods in the past few years. When Internet companies are promoting "Internet +", we also see many traditional business organizations saying that it is not "Internet +" but "+Internet". So where are those people who shout "+Internet" now? Some people think that the Internet is just a technology used to improve traditional things, and some Internet technologies can be added to traditional things. For example, if you use the Internet as email, you build an email system and think it is the Internet. But some people treat the Internet as a system and reconstruct the business from the bottom up. In the end, you will find that you are unemployed.

The second is decentralization. Why go to the center? Regional center technology in business has brought about business decentralization, which is an inevitable trend in history. Where is this trend? I think there are two points. One is economic globalization and entering version 2.0. Now through the Internet, it is no longer the company that is globalizing, nor the company turning itself into a multinational company, but the Internet is empowering any individual, so that it can sell its products through the Internet in a small county in China. worldwide. When economic globalization develops to personal globalization, solving point-to-point transactions and point-to-point services becomes a prominent issue. So the real-time clearing and settlement brought by blockchain technologyIt is estimated that these characteristics of point-to-point transaction settlement can help the globalization of personal business activities.

The third is the digitalization of the economy. When data is collected to a certain extent, its circulation is basically across time and space. The demand for financial payments from commercial activities is carried with them anytime and anywhere, and it is impossible to provide scenario-based and virtualized payment settlement anytime, anywhere and on demand. Services will eventually be eliminated by technology and the market.

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. 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.

⑸ In what fields can blockchain be applied?

According to incomplete statistics from Capital Lab, there will be a total of 1,290 global blockchain application cases in 2021. The number of cases is the same as 1,304 in 2020. Basically the same as before. These cases cover three major application types: financial applications, government applications and industry applications. Among them, financial applications account for 25%, and government applications account for 25%.Service applications account for 12%; except for the financial industry, applications in other industries account for 63%. Blockchain technology is accelerating its expansion into the industrial application market.
Take the blockchain unicorn company Qulian Technology as an example. Qulian Technology’s products are widely used in key fields such as finance, people’s livelihood, government affairs, justice, energy, manufacturing and other key fields. With 180+ typical applications, it is one of the best in the industry. The blockchain enterprise with the richest implementation scenarios.

⑹ What are the applications in the blockchain field?

Blockchain application fields:
1. Financial field. Blockchain has potentially 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 quickly completing transaction payments.

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 to be a promising application direction of blockchain.

3. Public service field. 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. 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 bePerform authentication to prove the existence of text, video, audio and other works to ensure 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 full life cycle management of digital copyright, and can also be used as a technical guarantee in judicial evidence collection. For example, Mine Labs, 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, there is no need for the policy holder to apply or the insurance company to approve it. As long as the claim settlement conditions are triggered, the insurance policy can automatically settle claims. 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 and exchange between individuals. high-value items are insured, and blockchain replaces the role of a third party 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.

⑺ What are the practical applications of blockchain technology

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

⑼ Application aspects 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, and can be publicly disclosed conditionally to facilitate public and social supervision on the premise of meeting the privacy protection of project participants and other relevant laws and regulations.

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.

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 ensures that each ownerThe organization promptly discovers problems arising during the operation of the supply chain system and finds targeted solutions, thereby 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 That 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 cannot be tampered with and can ensure the transparency of information nature, forming a common trust among competitors who do not trust each other. It can also 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
