㈠ How to integrate blockchain and sharing economy

In general, grasping the essence of blockchain should be weak control, decentralization, autonomous mechanism, and network architecture and coupled connections. The essence of blockchain should be a new social structure in the information society era that is completely different from industrial society. The five core points about blockchain have something in common with the sharing economy. The essence of the sharing economy is to abandon the old development mechanism and no longer emphasize concentration. Instead, use decentralized social resources in a peer-to-peer manner to allow participants to participate and contribute in different ways. to gain.
Blockchain and sharing economy, two mutually relevant Internet hotspots, happen to have ample "space for cooperation." From theory to practice, there have been many bold explorations in the industry, and there have even been some phenomena that challenge traditional business models. In this way, the sharing economy tied to the blockchain will be a brand new business model and a new subversion of interpersonal relationships. I plan to invest in the blockchain industry. After all, in the Internet era, I searched for Guangzhou Xuanling Technology Co., Ltd. and looked at the web page. They are a company that develops software blockchain smart contracts. There are many cases developed and the team is strong.

㈡ What are the practical applications of blockchain technology in the field of economics

Because the digital currency first produced by blockchain technology has had a huge impact on the financial field, research and application areas Blockchain technology has become an important task in today’s financial field. In essence, blockchain technology is still a technical means and tool. Its application in the financial field and its application in the real economy are both parallel. They have their own relative independence, but there is a certain overlap, that is, It is said that the promotion effect on the real economy is indirect. 1. Regardless of finance or entity, one of the foundations of transactions between supply and demand is trust. The current banks, enterprises, enterprises, people, etc. all use currency as a link. The right to issue currency lies with the state, and the right to operate lies with banks. With the further popularization and widespread application of blockchain technology, in the future, enterprises and enterprises, or individuals and individuals can self-organize the issuance of digital currencies (digital credit). Banks’ The status will change from the current monopoly operation to an equal competition operation in the market. Therefore, the widespread application of blockchain technology in the financial field has an indirect impact on the real economy. 2. Blockchain technology is the bridge between reality (entity) and virtuality. Through blockchain technology, the real world can be recreated, reconstructed and redefined in the virtual world. For example, real banknotes are digital currencies in the virtual world, real stock transactions are digital stock transactions in the virtual world, and real import and export trade are digital settlements, digital customs clearance, digital documents, bills, etc. in the virtual world. It greatly improves the efficiency of business processes and saves transaction costs. At present, all transactions are inseparable from banks. Banks play the role of central hubs in transactions. Banks’ application of blockchain technology will definitely improve the efficiency of their settlement and indirectly promote the efficiency of the real economy. However,This impact will gradually weaken in the future. Because the biggest feature of blockchain technology is decentralization, its distributed accounting system is a centerless network system. 3. The application of blockchain technology is actually to valorize and credit the information currently flowing on the Internet, and to reorganize and restructure the information in the Internet (use value, exchange value, cultural value) through the blockchain. The formation of the Internet of Value is of great significance and will bring revolutionary promotion to both the financial industry and the real economy.

㈢ Blockchain and Digital Economy

The top ten mainstream predictions for the development trend of the digital economy after the epidemic. See the figure for details.

Jeff briefly talks about his views:

1. The general trend of national and global economic development is the digital economy. This direction is undoubtedly certain!

2. Blockchain is not enough to be compared with the digital economy, Internet economy, and industrial economy, and the concept is wrong. Blockchain is a technology that can be discussed together with information technologies such as the Internet, cloud computing, 5G communications, and the Internet of Things, and should also be used in combination!

3. The product of the coupling of blockchain technology with tokens, token economy, and community governance may not necessarily be the current currency circle in the eyes of currency people. All the above mentioned must empower the real economy in order to exert its positive energy and generate new value.

4. There is a natural fit between the digital economy and blockchain technology. Therefore, it is recommended that blockchain practitioners de-monetize tokens and apply them to multiple applications to truly take advantage of the distributed advantages of blockchain.

Blockchain technology is finally easy to use!

㈣ How to understand the blockchain economy in a popular way

The principle of blockchain: decentralized distributed accounting system
The core of blockchain technology is all The currently participating nodes jointly maintain transactions and databases, which makes transactions based on cryptographic principles rather than trust, so that any two parties that reach an agreement can directly conduct payment transactions without the participation of a third party.
?
Technically speaking, a block is a data structure that records transactions, reflecting the flow of funds for a transaction. The blocks of transactions that have been reached in the system are connected together to form a main chain, and all nodes participating in the calculation record the main chain or part of the main chain. A block contains the following three parts: transaction information, hash hash formed by the previous block, and random number. Transaction information is the task data carried by the block, specifically including the private keys of both parties to the transaction, the number of transactions, the digital signature of electronic currency, etc.; the hash formed by the previous block is used to connect the blocks to realize the past The order of transactions; random numbers are the core of transaction completion. All miner nodes compete to calculate the answer to the random number. The node that gets the answer the fastest generates a new block and broadcasts it to all nodes for update, thus completing a transaction.

1.1 What is blockchain

BlockChain refers to a technical solution that collectively maintains a reliable database through decentralization and trustlessness. This technical solution mainly allows any number of nodes participating in the system to associate and generate a series of data blocks (blocks) using cryptographic methods. Each data block contains all the information exchange data of the system within a certain period of time, and generates The data fingerprint is used to verify the validity of its information and chain to the next database block.
?
In layman’s terms, blockchain technology refers to a way for all people to participate in accounting. Behind all systems there is a database, which is a big ledger. Then who will keep this ledger becomes very important. At present, it is whoever owns the system who keeps the accounts. The account books of each bank are kept by each bank, and the account books of each bank are kept by Alibaba. But now in the blockchain system, everyone in the system has the opportunity to participate in accounting. If there are new transaction data changes within a certain period of time, everyone in the system can do accounting. The system will judge the person who has the fastest and best accounting during this period, write the recorded content to the ledger, and Send the contents of the ledger during this period to all other people in the system for backup. In this way, everyone in the system has a complete ledger. Therefore, this data becomes very safe. A tamperer needs to modify more than half of the system node data at the same time to truly tamper with the data. Such tampering would be extremely costly, making it nearly impossible. For example, Bitcoin has been running for more than 7 years. Countless hackers around the world have tried to attack Bitcoin, but so far there have been no transaction errors. It can be considered that the Bitcoin blockchain has been proven to be a safe and reliable system.
?

1.2 Why is there blockchain innovation

Human beings need to communicate during their activities, and communication is based on information. In the past, information circulated It was not convenient enough to meet the information needs of market participants, so intermediaries and centers were born. This centralized system has problems such as high cost, low efficiency, value dispersion, "information islands" and insecure data storage. However, due to technical and environmental factors, this system continued to operate for many years until the emergence of the Internet. The starting point of the first generation of the Internet is the TCP/IP protocol, which is an open code that implements a unified format for peer-to-peer transmission of information by all nodes on the network, and brings the basic values ​​of freedom and equality required by a global unified market into programmed, protocol-based, and reliably Execution. The Internet eliminates low-value, high-cost intermediate chains and achieves low-cost and high-efficiency global information transmission in a decentralized manner.
?
However, the first generation of the Internet did not solve the problem of information credibility. Activities that can be decentralized on the Internet must be activities that do not require credit endorsement, and activities that require credit guarantee must be centralized activities involving third-party intermediaries. Therefore, Internet technology that cannot establish global credit has encountered great obstacles in its progress-people cannot use decentralized systems on the Internet.way to participate in any value exchange activities. To realize value exchange, people still need third-party intermediaries based on credit (such as banks, clearing houses, exchanges). The global centralized credit system still has problems such as high operating costs, low efficiency, and vulnerability to attacks and damage. For example, each country's legal currency has different credit values ​​and incompatible clearing systems, which adds a lot of cost to global trade.
?
Therefore, what the second generation Internet must break through is: how to establish global credit in a decentralized manner? Let value delivery be carried out at low cost and with high efficiency. We need to create a technology in the Internet that can engage in value exchange activities without ensuring that people trust each other, so as to achieve true decentralization and third-party intermediaries, and realize the transformation from the information Internet to The transformation of the Internet of Value.

1.3 Blockchain Application

Bubi Blockchain has been used in equity, supply chain, points and other fields, and is conducting trials and application tests with exchanges and banks. .
Shubei wallet, as a points application on the Bubi blockchain, has recently been launched, which is a good example for the application of blockchain technology in various industries.

1.4 Why the financial industry needs blockchain

Trust is the foundation of the financial industry. In order to maintain trust, the development of the financial industry has spawned a large number of high-cost, inefficient, and single-point-of-failure intermediaries, including custody, third-party payment, notaries, banks, exchanges, etc. Blockchain technology uses new encryption authentication technology and decentralized consensus mechanisms to maintain a complete, distributed, and tamper-proof ledger, allowing participants to communicate through a unified The ledger system ensures the security of funds and information. This has huge implications for finance. Therefore, global financial giants are exploring blockchain applications. On the one hand, they are to prevent the risk of being subverted. On the other hand, they are also "for my own use" to improve efficiency and reduce costs, thereby consolidating, optimizing and expanding existing power.
?
First, blockchain can reduce trust risks. Blockchain technology is open source and transparent. Participants in the system can know the operating rules of the system, verify the authenticity and integrity of the ledger content and ledger construction history, and ensure that the transaction history is reliable and has not been tampered with, which is equivalent to It improves the accountability of the system and reduces the trust risk of the system. For example, blockchain can avoid current Internet financial P2P scams, fraud and other incidents.
?
Second, blockchain can improve the efficiency of payment, transaction, and settlement. On the blockchain, the process of transaction confirmation is the process of clearing, settlement and auditing. Blockchain uses distributed accounting, and all transactions are displayed in real time on a spreadsheet similar to global sharing, and are settled in real time, greatly improving efficiency. For example, the U.S. securities settlement system is T+3, but blockchain can increase efficiency to the minute level, which can reduce settlement risks by 99%, thus effectivelyReduce capital costs and systemic risks.
?
Third, blockchain can reduce operating costs. Various financial business systems and back-end work often face long processes and multiple links. Today, both Visa and Master are centralized operations, and currency transfers must go through a third party. This makes cross-border transactions, currency exchange rates, internal accounting, and time costs too high, and brings risks to capital. Blockchain can simplify and automate lengthy financial service processes, reduce front-end and back-end interactions, and save a lot of manpower and material resources. This is of great significance to optimizing financial business processes and improving financial competitiveness. The Bank of Spain believes that blockchain technology will help the financial industry reduce bookkeeping costs by $20 billion by 2022.
?
Fourth, blockchain can effectively prevent failures and attacks. The traditional financial model is centered on finance such as exchanges or banks. Once the center fails or is attacked, it may cause the entire network to be paralyzed and transactions to be suspended. The blockchain is supported by many distributed nodes and computer servers on a peer-to-peer network. Problems in any part will not affect the overall operation, and each node saves a copy of the blockchain data. Therefore, the blockchain has built-in business continuity and has extremely high reliability and fault tolerance.
?
Fifth, blockchain can improve the level of automation. Since all files or assets can be embodied in the form of codes or ledgers, smart contracts and automated transactions can be implemented on the blockchain by setting up data processing programs on the blockchain. For example, smart contracts can write a set of financial terms into the agreement to ensure automatic execution of the contract and payment of breach of contract.
?
Sixth, blockchain can meet regulatory and auditing requirements. Records stored on the blockchain have the characteristics of transparency, traceability, and immutability. Any record, once written to the blockchain, is permanently saved and cannot be tampered with. Any transaction between two parties can be tracked and queried.
?
In addition to the above positive effects on existing systems and business models, blockchain can also drive the birth of new business models. On the one hand, the characteristics of blockchain technology enable it to realize some business models that are difficult to achieve in a centralized model. On the other hand, blockchain greatly encourages innovation and collaboration in the whole society through the openness and collaboration of source code. Of course, there will be many problems and challenges in the financial application of blockchain, and the article also considers them in specific applications.

The working principle of blockchain technology is not difficult to understand. If we focus on the application research of specific blockchain technology, we can find that the working principle of this blockchain technology is ubiquitous.

㈤ What signals does the Blockchain 3.0 era give us?

In 2020, blockchain was included in the category of "new infrastructure" by the country, and at least 7 provinces introduced district Blockchain support policy. In the same year, blockchain technology was gradually moving from concept to implementation, with many application scenarios blooming. "Blockchain" various industriesIndustrial applications have become a symbol of the continued 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 the "elimination trend". "real" good momentum.

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, various industrial application scenarios of "blockchain" 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 blockchain projects of listed companies.

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, and supply. Applications in 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 of the China Academy of Information and Communications Technology, believes that this process will continue for some time or longer. In the next step, blockchain technology competition will 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 clearly defined the alliance chain as theBased on the development idea of ​​serving the real economy and optimizing public services, the direction of industrial development has been further clarified. 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 sales 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. Now it has been explored and applied in government affairs, people's livelihood, industrial management and other industries, and its application scenarios are becoming increasingly rich, presenting It has shown 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 account for half of all applications. Others such as government affairs,People's livelihood and other areas have become key areas for manufacturers to deploy in the future and 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.

㈥ How blockchain technology can play a greater role in economic and social development

As the construction of a transportation power continues

In September 2019, the Central Committee of the Communist Party of China and the State Council The "Outline for Building a Powerful Transportation Nation" was issued, and it is planned to basically build a strong transportation country by 2035. In the "Outline for Building a Powerful Transportation Nation", in addition to "reducing costs and increasing efficiency" in my country's transportation based on existing infrastructure, advanced transportation equipment plays an "innovative" role, mainly transforming the incremental growth of my country's transportation. In the "Outline for Building a Powerful Transportation Nation", advanced equipment mainly includes large-scale carriers and special equipment to promote the upgrading of equipment technology; research and development of autonomous driving, vehicle-road collaboration, underwater robots, large-scale deep-sea multi-functional rescue ships, etc.; and the widespread use of smart high-speed rail , smart roads, smart shipping, etc.

㈦ What is blockchain technology? What exactly is blockchain?

In a narrow sense, blockchain is a Time sequence combines data blocks into a chained data structure in a sequential manner, and is cryptographically guaranteed to be a distributed ledger that cannot be tampered with or forged.

Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure data transmission and access. It is a new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data securely.

[Infrastructure]

Generally speaking, the blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer composition. Among them, the data layer encapsulates the underlying data blocks and related basic data and basic algorithms such as data encryption and timestamps; the network layer includes distributed networking mechanisms, data dissemination mechanisms, and data verification mechanisms; the consensus layer mainly encapsulates network nodes Various consensus algorithms; the incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives; the contract layer mainly encapsulates various scripts, algorithms and smart contracts, and is the core of the blockchain The basis of programmable features; the application layer encapsulates various application scenarios and cases of the blockchain. In this model, the chain block structure based on timestamps, the consensus mechanism of distributed nodes, economic incentives based on consensus computing power, and flexible programmable smart contracts are the most representative innovations of blockchain technology.

Extended information:

[Blockchain core technology]

Blockchain mainly solves the trust and security issues of transactions, so it proposes four technological innovations to address this issue:

1. Distributed ledger, which means transaction accounting is distributed among Multiple nodes in different places complete it together, and each node records a complete account, so they can all participate in supervising the legality of the transaction and can also jointly testify for it.

The uniqueness of blockchain's distributed storage is mainly reflected in two aspects: First, each node of the blockchain stores complete data according to the block chain structure. Traditional distributed storage generally stores The data is divided into multiple parts for storage according to certain rules. Second, the storage of each node in the blockchain is independent and of equal status, relying on the consensus mechanism to ensure storage consistency, while traditional distributed storage generally synchronizes data to other backup nodes through the central node.

No node can record ledger data independently, thus avoiding the possibility of a single bookkeeper being controlled or bribed to record false accounts. Also because there are enough accounting nodes, theoretically speaking, the accounts will not be lost unless all nodes are destroyed, thereby ensuring the security of the accounting data.

2. Asymmetric encryption and authorization technology. Transaction information stored on the blockchain is public, but account identity information is highly encrypted and can only be accessed with authorization from the data owner. , thus ensuring data security and personal privacy.

3. The consensus mechanism is how all accounting nodes reach a consensus to determine the validity of a record. This is both a means of identification and a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and strike a balance between efficiency and security.

The consensus mechanism of the blockchain has the characteristics of "the minority obeys the majority" and "everyone is equal". "The minority obeys the majority" does not entirely refer to the number of nodes, but can also be the computing power and the number of shares. Or other characteristic quantities that the computer can compare. "Everyone is equal" means that when a node meets the conditions, all nodes have the right to give priority to the consensus result, which will be directly recognized by other nodes and may eventually become the final consensus result.

4. Smart contracts. Smart contracts are based on these trustworthy and non-tamperable data and can automatically execute some predefined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and trustworthy, it will be easy to automate claims settlement in some standardized insurance products.

In the daily business of insurance companies, although transactions are not as frequent as those in the banking and securities industries, the reliance on trusted data continues unabated. Therefore, the author believes that using blockchain technology from the perspective of data management can effectively help insurance companies improve their risk management capabilities. Specifically speaking, it is mainly divided into risk management of policyholders and risk supervision of insurance companies.

Blockchain-Network

㈧ Digital Economic EraBlockchain innovation application scenarios continue to expand

In the era of digital economy, blockchain, as a new driving force for economic growth, is leading a new round of global technological revolution and industrial transformation. At present, blockchain is developing rapidly and penetrating into all areas of our country's economy, which not only strengthens the resource allocation capabilities of the digital economy, but is also of great significance for promoting high-quality economic development and improving the modernization of the national governance system and governance capabilities.

Blockchain is the new engine driving digital development

As the role of blockchain in the digital economy grows, its innovative applications continue to expand. According to the "China Mobile Internet Development Report (2021)", "There were nearly 2,000 blockchain projects across the country last year, and the blockchain market size exceeded 3.2 billion yuan."

China Academy of Information and Communications Technology Industrial Internet and Liu Yang, deputy chief engineer of the Internet of Things Research Institute, once said that blockchain is a trust infrastructure necessary for the development of economic activities. It provides inclusive public services for finance, agriculture, industry, energy and other industries and the public. It is also a Collaboration tools, transforming production relations, and integrating with the real economy will improve collaboration efficiency and reduce costs.

In fact, blockchain is called "the next generation of Internet-level technology" because of its disruptive innovation, and is considered the most revolutionary among strategic emerging technologies. In October 2019, blockchain was elevated to a national strategic level. In April 2020, blockchain was included in the new infrastructure and was listed as one of the seven "key digital economy industries" in the "14th Five-Year Plan". In the future, blockchain will usher in new opportunities for innovation and development.

However, Zhang Chao said that currently, data governance on the blockchain is still a huge challenge at a global level. First, data governance requires a clear regulatory subject, but in blockchains or distributed ledgers (or public chains) other than alliance chains, a relatively clear object may not be found as a regulatory subject; secondly, due to the The data on the chain cannot be easily tampered with, which means that during the data governance process, the rights of the data owner to modify and delete the data may not be fully protected.

Blockchain innovative application scenarios continue to expand

Driven by favorable policies and market demand, blockchain innovative application scenarios continue to expand. In recent years, in addition to the two major outbreak scenarios of finance and government affairs, there is even more promise in empowering the field of rule of law. On the one hand, the multi-faceted and multi-field application of "blockchain + rule of law" can effectively improve the efficiency of rule of law construction; on the other hand, blockchain technology can also help public prosecutors and law enforcement agencies crack new criminal cases.

Industry insiders believe that based on the analysis and tracking of massive on-chain data, blockchain technology provides governments, enterprises and users with on-chain data monitoring, transaction maps and on-chain address analysis. In response to suspected criminal activities such as virtual currency,The blockchain browser provides on-chain data tracking, combats virtual currency crimes, maintains national financial security, and provides "blockchain power" for the construction of Digital China.
