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 or token, and can implement customized smart contracts. When certain constraints are reached, there is no need to go through the thirdThe three parties can automatically execute it, which is the basis for trustlessness 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 it. 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. Then the real-time clearing and settlement and point-to-point transaction settlement brought by blockchain technology can just 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, but 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.

⑶ What is the application of blockchain and what is the technical field

1. Application of blockchain

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

2. Blockchain technology field

1. Financial field

Block chain technology is used in international exchange, letters of credit, equity registration and securities transactions It has potential huge application value in other financial fields.

Internet of Things and Logistics Fields

Blockchain can also be naturally combined in the Internet of Things and logistics fields.

2. Public service fields

Blockchain is closely related to people’s production and life in public management, energy, transportation and other fields, but the centralized nature of these fields also brings Some problems can be solved using blockchain.

3. Digital copyright field

Through blockchain technology, works can be authenticated, proving the existence of text, video, audio and other works, and ensuring the authenticity of the copyright owner. , uniqueness. 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.

4. 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.

5. 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.

⑷Which book is "Blockchain Technology and Application" about the application and development of blockchain technology and digital currency?

According to relevant query information, "Blockchain Technology and Applications" is a book published by Higher Education Press on May 1, 2022, and is China's first blockchain textbook. Blockchain is a chain composed of blocks one after another. Each block stores certain information and is connected into a chain according to the time sequence of their respective generation.

⑸ What to study in the blockchain technology application major

The blockchain technology application major studies the financial field, insurance field, Internet of Things and logistics field, digital version field, and public service field. It can be seen that the development prospects and employment fields of the blockchain engineering major are relatively broad.

Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it is "unforgeable", "full traces" and "traceable"Features such as “openness and transparency” and “collective maintenance”. Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.

Blockchain technology:

This major cultivates the comprehensive development of moral, intellectual, physical, artistic and labor skills, and masters the basic knowledge of natural sciences, humanities and social sciences, and the basics of computer science Theory, basic theory and application knowledge of blockchain technology and application, competition and team awareness and craftsman spirit, high-quality and high-level technical skills talents who can engage in blockchain technology design, management, service and other work.

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.
