以上就是关于区块链技术如何拓展三个相关关键词：去中心化，智能合约和共识机制的介绍。区块链技术可以改善传统的业务流程，提高数据安全性，降低交易成本，防止欺诈行为，保护系统的完整性，并有效地降低系统运行的成本。

① How is blockchain developing now

In 2020, blockchain was included in the category of "new infrastructure" by the country, and at least 7 provinces introduced blockchain Support policies. In the same year, blockchain technology was gradually moving from concept to implementation, with many application scenarios blooming. "Blockchain+" various industry applications have become a symbol of the continuous maturity of blockchain.

The development status of "Blockchain+" in 2020

In 2020, the COVID-19 epidemic swept the world, and the uncertainty of world economic development increased significantly. Governments and enterprises of various countries are exploring the use of emerging technologies to reduce economic and social operating costs, improve the operating efficiency of the real economy, and further find new growth points for economic development.

At present, blockchain is cross-innovating with new technology infrastructure such as cloud computing and artificial intelligence. More and more vertical fields of the real economy are showing the development pattern of "blockchain +" and "escape from reality". The good momentum of "Towards Reality".

In order to avoid turning reality into fiction, in addition to continuing to severely crack down on speculation, we must also guide the deep integration of blockchain technology with practical application scenarios. Therefore, "blockchain+" various industrial application scenarios have become one of the inevitable trends in the development of blockchain.

According to the "Blockchain White Paper (2020)" recently released by the China Academy of Information and Communications Technology, as of October 2020, more than 262 listed companies have been involved in the blockchain field, each from insurance , real estate, commercial department stores, security equipment, packaging materials, telecommunications operations and other 39 fields. In the blockchain information service registration list released by the State Internet Information Office, there are 45 listed company blockchain projects.

Among them, finance is the most explored scenario among blockchain technology application scenarios, with specific projects implemented in subdivisions such as supply chain finance, trade finance, payment and settlement, and fund management. The white paper shows that as of November 2020, among the domestically registered blockchain information services, the number of projects in the financial (including supply chain finance) field ranks first, accounting for as high as 36%.

As the implementation of blockchain applications accelerates, "blockchain +" business has become the focus of development for Internet backbone enterprises to enter the blockchain industry. In addition to financial business, they actively deploy the Internet, traceability, Applications in supply chain & logistics, digital assets, government affairs and public services, intellectual property, law, medical and other fields.

At the same time, the industry is gradually understanding that blockchain is the basic component of trusted transactions, but this does not mean that blockchain can conquer the world. Blockchain needs to be combined with other technologies such as artificial intelligence, Internet of Things, big data, 5G, etc. to use synergy to form integrated solutions to jointly promote digital transformation.

According to relevant data, the current application of blockchain is mainly in the field of certificate storage. Blockchain has entered into how to make it better from an engineering perspective, more credible, more stable, and more scalable. Well, a stage that can accommodate more nodes. He Baohong, Director of the Institute of Cloud Computing and Big Data, China Academy of Information and Communications TechnologyIt is believed that this process will continue for some time or longer, and the next step is for blockchain technology competition to shift from engineering optimization and improvement to technology ecology and business ecology.

In addition, it is understood that the blockchain industry is improving in the long term, and industry cognition has returned to rationality. With the central government's planning and guidance for the development of blockchain technology, my country's blockchain has clarified the development ideas based on the alliance chain, focusing on serving the real economy and optimizing public services, and the direction of industrial development has become clearer. At this stage, the confidence of the majority of practitioners in blockchain continues to improve, and the long-term strategic value of blockchain is generally recognized.

What is the prospect of "Blockchain+" in 2021?

As my country’s blockchain industry chain gradually improves, most blockchain companies not only focus on one aspect, but also show a trend of coordinated development in multiple fields. According to statistics, among the 801 blockchain information service registration lists released by the Cyberspace Administration of China, Beijing, Guangzhou, Shanghai, Zhejiang, Jiangsu, and Shandong are the provinces and cities with the most registered companies.

The core role of blockchain corresponding to its technical characteristics is mainly reflected in the three aspects of certificate storage, automated collaboration and value transfer. As its value potential is constantly being explored, application scenarios have evolved from the breakthrough point of finance. , and gradually expanded into many fields such as the real economy, government affairs and people's livelihood.

The core value of blockchain for the real economy is to promote efficient collaboration between upstream and downstream industries and improve the efficiency of industry-finance integration. In the early stages of development, the blockchain application model mainly focused on the storage of documents, contracts, etc. At this stage, blockchain industry applications are gradually moving towards automated collaboration and value interconnection such as government data sharing, supply chain collaboration, and cross-border trade.

2020 is the warm-up for 2021. In 2021, the use of blockchain, distributed ledgers, and smart contract tools will continue to grow as it did in 2020. With the continuous deepening of blockchain technology, the foundation of the blockchain industry will become better and better, the industrial ecology will also develop rapidly, and the industrial chain will become increasingly widespread.

From the perspective of industrial structure, the blockchain industry is mainly divided into four parts: underlying technology, platform services, industrial applications, and peripheral services.

The first three parts show a relatively obvious upstream and downstream relationship. The underlying technology part provides the necessary technical products and components of the blockchain respectively. The platform service part builds an area that can run corresponding industry applications based on the underlying technology. The industrial application part of the blockchain platform mainly uses blockchain technology to develop industry applications based on the actual scenarios of various industries and realize the innovation of business collaboration models within the industry.

The peripheral services part provides supporting services to the industry, including industry organizations, market research, standard formulation, system evaluation and certification, industry media, etc., to provide impetus for the development of industrial ecology.

Among them, as far as the industrial application of blockchain is concerned: Blockchain is the innovative development result of information technology, and it is also the main booster for the reconstruction of business processes and the innovation of industrial interaction models in various industries.

Blockchain has gradually expanded from the initial digital finance to supply chain finance, product traceability and other fields.It has been widely used in government affairs, people's livelihood, industrial management and other industries. Its application scenarios are becoming increasingly rich, showing a development trend of deep integration with other industries.

At present, domestic enterprises are focusing on the development of applications related to serving the real economy and improving government affairs and people's livelihood. Among them, supply chain finance and product traceability have accounted for half of all applications. Others, such as government affairs and people's livelihood, have become the future of manufacturers. Key layout areas are about to experience explosive growth.

After blockchain investment cooled down in 2020, the blockchain industry may begin to gradually become more rational in 2021. However, a relatively complete industrial chain and active market entities provide a good foundation for the integrated development of the blockchain industry. The blockchain industry will also show a positive development trend in terms of policy support, ecological construction, platform services, application implementation, and integrated innovation.
