⑴ What is digital currency, digital finance and why blockchain digital currency is so important

From a financial perspective, blockchain and digital currency are actually a new generation digital financial system. The digital financial system is built on the financial infrastructure of blockchain digital currency.

From the perspective of an enterprise, how do we understand the digital economy?

We know that the driver of the industrial economy is fossil fuels, and the driver of the digital economy is data. So how does data drive a business? I summarize it as computer modeling of data, using algorithms to organize the data, and at the same time computer programming of the enterprise's business processes, turning the data into algorithm models, and then stringing together the algorithm models to turn the business processes into computer programs. Or become a smart contract, which is digital technology. This digital economy is not the digital economy from an economist’s perspective.

How to integrate these things requires a series of digital technologies. A series of digital technologies such as the Internet, Internet of Things, cloud computing, artificial intelligence and blockchain constitute the digital economy, or digital business.

Digital technology has three characteristics. The first is that it spans time and space, because data naturally has the ability to penetrate. For example, cross-border and cross-organization data flow cannot be blocked by national borders, so it crosses time and space. At the same time, data is penetrable. It can penetrate the market vertically, eliminating all intermediaries and hierarchies in the middle, and then Let transactions become peer-to-peer, and buyers and sellers no longer need intermediaries. It can penetrate the market vertically and shorten the industrial chain horizontally. Peer-to-peer, there is no middleman to guarantee the transaction settlement.

The core of digital finance is point-to-point payment settlement and non-guaranteed transaction settlement. Nowadays, using bank cards to buy things in shopping malls is not a point-to-point transaction. It takes time for the merchant to receive the money, and the bank guarantees that the transaction can be settled completely. But if these intermediaries disappear, how can transactions be cleared and settled in real time? At present, blockchain and digital currency are the best technical solutions to solve these problems, and no other better solution has been found yet.

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 areWhen 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. 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, 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.

Why is digital currency so important?

First, the issuance of digital currency broadens the scope of original monetary policy options. If all physical currencies can be converted into digital currencies, this will make it possible for the central bank to break through the zero lower bound of interest rates and reduce nominal interest rates to negative.

In addition, digital currency also provides a new quantitative easing tool. The central bank issues an equal amount of digital currency to every citizen in the form of free payment, which can directly bypass the inefficiency during the crisis. Financial markets, improve citizens’ ability to consume and repay debt, making it easier to achieve the central bank’s monetary policy goal of calming volatility.

Second, digital currency can make monetary policy more transparent. Economic theory generally believes that the implementation of monetary policy should be systematic and transparent, which can enhance the effectiveness of the monetary transmission mechanism, reduce internal noise, and strengthen the stability of the system.

Although, central banks in various countries have made significant progress in this regard by controlling inflation targets. The implementation of central bank digital currencies provides an opportunity to increase the transparency of central bank monetary policy frameworks. By adopting a central bank digital currency, like inflation targeting, the central bank can establish a fixed, specific price index toA stated price level target, thus providing a durable, credible and transparent nominal anchor to the economic system.

Third, the issuance of digital currency can solve the problem of reduced physical cash and bring some seigniorage to the central bank. With the rise of mobile payment methods and mobile payment applications, the importance of cash in society is gradually decreasing.

With the demise of paper money, the only form of money circulating in the economy will be residents' bank deposits, and central banks may lose the power to issue banknotes to the public. Additionally, under the current system, seigniorage can only be obtained through the issuance of physical cash. Therefore, when ordinary people are less willing to hold cash, providing a convenient central bank digital currency that can be connected to electronic payment systems can allow the central bank to regain part of the seigniorage.

Fourth, digital currency can increase the stability of the financial system. From a technical perspective, digital currencies allow residents, businesses and non-bank financial institutions to settle directly with central bank digital currencies. This can share part of the settlement functions of commercial banks and reduce the concentration of liquidity and credit risks in the payment system.

Of course, in specific policy practice, due to the need for policy stability, central bank digital currency can also be issued and operated relying on the commercial banking system.

In addition, digital currencies issued by central banks can provide a truly risk-free alternative to bank deposits. The shift of residents from holding bank deposits to holding digital cash reduces part of the need for government guarantees on deposits and weakens a source of moral hazard in the financial system.

⑵ Blockchain Principle

Blockchain is a technology, but it is not a single technology, but the result of the integration of multiple technologies, including cryptography, Mathematics, economics, network science, etc. You can think of it as a distributed shared accounting technology, or as a database, but this database is jointly maintained by all nodes on the chain, and each node has a ledger, because all nodes The ledgers are consistent, different nodes can trust each other, and there is no doubt about the data, so everyone says that the blockchain has technically achieved trust. For detailed professional technology, you can consult some professional technology companies. For example: Jinbo Technology, which focuses on developing blockchain-related products, has a professional R&D team and complete after-sales service. You can call for consultation.

⑶ What exactly is blockchain

On April 8, Wu Xiaoqiu, Vice President of Renmin University of China and Director of the Institute of Finance, spoke at the Boao Forum for Asia 2018 Annual Meeting media meeting He said that technology is penetrating finance at an unprecedented speed, China's financial industry is diversified, and new industries such as technology and finance are developing rapidly.

Supervision should be conducive to financial innovation

Wu Xiaoqiu pointed out that while China’s financial reform is advancing, it has also brought some confusion to financial supervision and requires in-depth think. The first is to move away from the single regulatory agency in the pastrisks, shifting to better management of market risks, thus requiring adjustments and reforms to the financial architecture.

According to the State Council’s institutional reform plan, China’s financial regulatory system has launched a “one bank and two conferences” structure. In this regard, Wu Xiaoqiu said that this is a pragmatic arrangement. The China Banking and Insurance Regulatory Commission will strengthen institutional supervision, and the China Securities Regulatory Commission will strengthen market supervision.

⑷ What is blockchain

From a scientific and technological perspective, blockchain technology involves many scientific and technological issues such as mathematics courses, cryptographic algorithms, big data technology and computer programming. From an application perspective, to put it simply, blockchain is a resource sharing ledger and database of a distributed framework, which has the characteristics of decentralization, inability to forge, traces of the entire process, traceability, collective maintenance, openness and transparency.

Based on this characteristic, blockchain technology establishes a reliable "trust" foundation and creates a reliable "collaboration" system, which has broad value. In recent years, the world's attitude towards Bitcoin has been ups and downs, but blockchain technology, as one of the basic technologies of Bitcoin, has received more and more attention. In the Bitcoin generation process, a block is a storage unit that records all information exchanges of each block node within the corresponding time period. The intermediate links between each block are achieved according to random distribution (also known as hash algorithm), and the subsequent block contains the hash value of the subsequent block. As the exchange of information expanded, 1 block and 1 block continued, and the result became known as blockchain technology.

Blockchain technology, as an auxiliary technology, does not decentralize the entire energy network, but makes the energy network more closely connected. Each network can be "autonomous" while maintaining independence. This independence can While improving the work efficiency of each outlet, it can also reduce the work efficiency of each outlet and avoid the energy loss of "intermediate links".

⑸ Does blockchain have a future in China?

Major companies in the industry: Ping An of China (601318), Donggang Holdings (002117), Information Development (300469), Yuanguang Software (002063) ), Boss Software (300525), Feitian Integrity (300386), Sifang Jingchuang (300468), Industrial and Commercial Bank of China (601398), SF Holding (002352)

Industry overview

1. Definition

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.

Blockchain is not a single technology, but a combination of new technologies. Each of these technologies performs its own role, solves different problems, and is combined to form a blockchain. As the basic structural unit of the blockchain, the block consists of two parts: the block header and the block body containing transaction data.

2. Industry chain analysis: the downstream industry covers a wide range of areas

The upstream of the blockchain industry chain is mainly the underlying technology and infrastructure. The underlying technology includes core basic components, protocols and algorithms. Represented by Bitcoin, Litecoin, and Ethereum, a network environment such as distributed algorithms, digital keys, data storage, P2P network protocols, and consensus mechanisms based on blockchain technology, transaction rules, and incentives for miners to join network nodes have been built. Mechanism, representative companies include Xiaoyi, Quantum Chain, Wanxiang Blockchain, etc.; the infrastructure is mainly mining machines.

The midstream is the platform layer, which mainly provides developers with applications based on blockchain technology. It provides productized services such as smart contracts, information security, and data services based on the underlying technology to improve development It provides convenience and scalability for developers to develop applications at the platform layer.

Downstream is the vertical industry application layer. It manifests itself as core application components, including smart contracts, programmable assets, incentive mechanisms, member management, etc.

Industry development history: We are in the era of blockchain 3.0

From the perspective of the development history of global blockchain, in 2008, an anonymous person signed by "Satoshi Nakamoto" published The paper "Bitcoin: Peer-to-Peer Network Electronic Cash System" originally expected to launch a peer-to-peer electronic cash that could circulate freely. The issuance of Bitcoin represented the beginning of blockchain technology; later, in 2013, the launch of Ethereum directly Pushing the blockchain into the 2.0 era; at the end of 2017, the popularity of stablecoins and the launch of MakerDAO pushed the blockchain into the 3.0 era. By June 2019, Facebook released the Libra white paper, which attracted attention and discussion from all walks of life around the world, and various countries regulated Departments have spoken out one after another, showing the huge potential of blockchain technology in reshaping global financial infrastructure. After entering 2021, NFT-based identification technology has emerged and is the first to be applied in the art field.

Industry policy background: Promote the all-round development of blockchain

In 2016, the State Council issued the "Thirteenth Five-Year Plan for National Informatization", which listed blockchain as a new technology for the first time The scope and cutting-edge layout indicate that my country has begun to promote the development of blockchain technology and applications. Since then, various localities in the country have successively introduced blockchain-related policies, providing a good environment for the development of blockchain.

In February 2019, the "Blockchain Information Service Management Regulations" issued by the State Internet Information Office were officially implemented, standardizing the filing basis for the development of my country's blockchain industry. The purpose of promulgating the "Regulations" is to clarify the information security management responsibilities of blockchain information service providers, standardize and promote the healthy development of blockchain technology and related services, and avoid blockchain information service security risks.Provide an effective legal basis for the provision, use and management of blockchain information services. The introduction of this "management regulations" also means that my country's "supervision era" for blockchain information services has officially arrived.

At the end of October 2019, the Political Bureau of the CPC Central Committee held its 18th collective study session on the development status and trends of blockchain technology. Central leaders clearly emphasized the use of blockchain as an important breakthrough for independent innovation of core technologies. , Accelerate the promotion of blockchain technology and industrial innovation and development. This fully demonstrates that blockchain technology has risen to a national level. Chen Chun, a professor at Zhejiang University and an academician of the Chinese Academy of Engineering, who gave a lecture on the collective study of the Political Bureau of the CPC Central Committee, said at the 2019CCF Blockchain Technology Conference hosted by the Computer Society of China on October 12 that the development of the domestic blockchain industry is ushering in " "Spring Breeze", the research hotspots of China's blockchain technology will focus on two aspects: the key technology of the alliance blockchain and the blockchain supervision technology.

Current development of the industry

1. The market size will grow by more than 90% in 2020

From 2016 to 2018, large IT Internet companies have deployed blockchain. Start-ups have entered a blowout mode, and the industry scale continues to expand. According to IDC data, China's blockchain industry has experienced changes from a market size of US$85 million in 2017 to an industry scale of US$561 million in 2020.

2. The number of related companies is growing rapidly

In terms of the number of companies, in 2020H1, my country provided blockchain professional technical support, products, solutions and other services, and had input or output The number of new blockchain companies reached 303, a year-on-year increase of 274.07% nationwide. As of the end of 2020, the number of blockchain-related companies in my country reached 64,062, a year-on-year increase of 52.88%.

3. Blockchain finance is the largest downstream application market

According to the disclosure of the "China Blockchain Development White Paper (2020)", 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, it actively deploys the Internet, traceability, supply chain & logistics, digital assets, government affairs and public services, intellectual property, and law. , medical and other fields of application. Among them, finance is the most explored field in the application scenarios of blockchain technology, with specific projects implemented in subdivided fields such as supply chain finance, trade finance, payment and settlement, and fund management.

4. The number of blockchain tenders is increasing year by year

From a year perspective, from 2016 to 2020, the number of government tenders for blockchain-related projects has been growing exponentially. , on the one hand, it benefits from the increasingly prominent application value of blockchain technology, and on the other hand, it also reflects the government’s increased demand for and emphasis on blockchain.

Industry competition situation

1. Regional competition: Beijing and Guangdong have the most blockchain technology research and development-related enterprises

In the companyIn terms of distribution, as of the first half of 2021, the distribution of enterprises has become clearly tiered. Among them, Beijing and Guangdong rank in the first echelon with 348 and 341 blockchain development-related companies respectively, and the number of companies in Jiangsu, Shanghai, and Zhejiang reaches 164, 127, and 81 respectively.

As an important carrier for the development of blockchain industrial clusters, local governments are accelerating the construction of blockchain industrial parks. Judging from the location distribution of industrial parks, there are a large number of blockchain industrial parks in cities such as Beijing, Shanghai, Hangzhou, Guangzhou, Chongqing, Qingdao, and Changsha, forming a Bohai Rim agglomeration effect dominated by Beijing and Shandong, with Zhejiang and Shanghai , the agglomeration effect of the Yangtze River Delta dominated by Jiangsu, the agglomeration effect of the Pearl River Delta dominated by Guangdong, and the agglomeration effect of Hunan, Guizhou, and Chongqing dominated by Chongqing and Hunan. Combined with the positioning and development of the industrial park, it is based on the premise of serving enterprises to create a blockchain innovation platform and industrial highland. This positioning also provides the basis for the aggregation effect of enterprises.

2. Enterprise competition: Alibaba’s blockchain is the strongest

In March 2021, at the China Mobile Communications Federation Blockchain Professional Committee and the China Science and Technology System Reform Research Association Under the guidance of the Digital Economy Development Research Group and the Organizing Committee of China’s Top 100 Blockchain Enterprises List, Chain Tower Think Tank screened and evaluated thousands of projects and enterprise lists, and finally released the 2020 China’s Top 100 Blockchain Enterprises List.

In the context of the outbreak of the epidemic in 2020, the 2020 Blockchain Top 100 List has adjusted the dimensions of enterprise inspection to a certain extent to highlight the performance of outstanding blockchain companies in 2020. It is divided into five main dimensions, namely commercial operation weight accounting for 25%, technology research and development weight accounting for 20%, product application weight accounting for 30%, team composition weight accounting for 15% and marketing promotion accounting for 10%.

Industry development prospects and trend predictions

1. It is still in the introduction period

Currently, my country’s blockchain industry is in the introduction period, and the industry is showing Two main characteristics: First, large industry enterprises are actively applying blockchain technology to improve their own businesses, but they are still mainly trying, and the main application scenarios are also non-core businesses in the industry. For example, enterprises such as Ping An of China, China UnionPay, and Ant Financial are limited to non-core businesses in their exploration of blockchain applications; secondly, the business development of enterprises focusing on blockchain technology services is mostly in the initial stage, and their product technology systems and The business model is not mature enough, and the demand side’s understanding of blockchain needs to be improved. Blockchain has already formed some application cases in scenarios such as judicial certificate storage, government affairs management, people's livelihood services, food traceability, supply chain management, etc., but it still needs to be further optimized and improved.

2. The market capacity is expected to exceed US$16 billion in 2026

Blockchain technology is a key direction for China’s new generation of independent innovation breakthroughs in information technology, and it contains huge innovation space. In the fields of chips, big data, cloud computing and other fields, innovation activities are becoming increasingly active, and innovation elements are constantly accumulating. Blockchain technology is increasingly used in various industriesDeepening will give rise to a large number of new technologies, new products, new applications, and new models.

China focuses on accelerating the transformation of its economic development model, pays more attention to the improvement of economic quality and people's living standards, and uses new generation information technology, including blockchain technology, to transform and upgrade traditional industries and enhance the quality of traditional industries. Develop quality and efficiency, and improve the level of smart social management, public services and home life. The huge market demand in the future will bring rare development opportunities and broad development space to blockchain technology. Researchers compiled and analyzed that China’s blockchain market will maintain rapid growth, with a compound annual growth rate of 73% in market size from 2021 to 2026. The market size in 2026 will reach US$16.368 billion, and in the next 20 years, China’s blockchain market will The industry market size is expected to reach the trillion level.

The above data refers to the "China Blockchain Industry Market Foresight and Investment Strategic Planning Analysis Report" by the Qianzhan Industry Research Institute.

⑹ Is blockchain investment true or false?

Legal objectivity:

Article 123 of the "Civil Code of the People's Republic of China" states that civil subjects enjoy intellectual property rights in accordance with the law. Intellectual property rights are the exclusive rights enjoyed by obligees in accordance with the law with respect to the following objects: (1) works; (2) inventions, utility models, and designs; (3) trademarks; (4) geographical indications; (5) trade secrets; 6) Integrated circuit layout design; (7) New plant varieties; (8) Other objects specified by law.

Legal subjectivity:

Blockchain technology itself is not a scam, but it does not rule out that some people use blockchain as a cover to commit scams. Several problems exist in blockchain: 1. The problem of excessive blockchain size. With the development of blockchain, the volume of blockchain data stored by nodes will become larger and larger, and the storage and computing burden will become increasingly large. The heavier. Taking the Bitcoin blockchain as an example, the size of its complete data currently reaches about 71GB. If a user uses the Bitcoin Core client to synchronize data, it may not be possible to complete the synchronization for three days and three nights. Moreover, the data of the blockchain The volume is still increasing, which brings a great threshold to the operation of the Bitcoin Core client. 2. The problem of blockchain data confirmation time. The current blockchain system, especially the financial blockchain system, has the problem of long data confirmation time. Taking the Bitcoin blockchain as an example, the current confirmation time of a Bitcoin transaction takes about 10 minutes. In the case of 6 confirmations, you need to wait for about 1 hour. Of course, for credit card transactions, the confirmation time is 2 to 3 days. Bitcoin has made great progress, but it is still far from the ideal state. 3. Dealing with the problem of transaction frequency The blockchain system faces the problem of too low transaction frequency. Taking the Bitcoin blockchain as an example, the average size of each transaction is about 250 bytes. If the block size is limited to 1MB, the number of transactions that can be accommodated is 4,000. Calculated based on the rate of generating one block every 10 minutes, 144 blocks can be generated every day, which means that Yunzhou can accommodate 576,000 transactions. Divided by the number of seconds per day, 86,400, Bitcoin blocksThe chain can handle up to 6.67 transactions per second. Currently, the actual daily transaction volume on the Bitcoin blockchain is close to the system bottleneck (picture). If the expansion problem is not resolved, it may cause congestion and delays in a large number of transactions. Average number of transactions in Bitcoin blocks (Source: Block Yuan) In comparison, Paypal's overall number of transactions in the third quarter of 2013 was 729 million, with an average of 93.75 transactions per second. Information from the official website of VISA, the world's largest payment card, shows that VisaNet achieved a processing capacity of 47,000 transactions per second in a 2013 test. Compared with several major payment networks such as Alipay, the Bitcoin blockchain is more like a newborn baby in terms of transaction processing frequency. Of course, this was also an early deliberate design by Satoshi Nakamoto. The Bitcoin block size was limited to 1MB to avoid the malicious behavior of rogue miners and have a negative impact on people. Bitcoin blockchain payment The reason why the Internet has grown to be worth billions of dollars today is that it is decentralized. 4. The development of blockchain is restricted by the current system. On the one hand, the decentralized and autonomous characteristics of blockchain dilute the concept of national supervision and have an impact on the current system. For example, digital currencies represented by Bitcoin not only pose a challenge to the country's right to issue currency, but also affect the transmission effect of monetary policy, weakening the central bank's ability to regulate the economy, causing monetary authorities to remain cautious about the development of digital currencies. On the other hand, regulatory authorities also lack full understanding and expectations of this new technology, and the establishment of laws and systems may lag behind, resulting in a lack of necessary institutional norms and legal protection for economic activities related to the use of blockchain, which inadvertently increases reduce the risks of market entities. 5. The integration cost of blockchain technology and existing systems is relatively high. For any innovation, existing institutions must ensure that it can not only create economic benefits, but also comply with regulatory requirements and connect with traditional infrastructure. Especially when deploying a new basic system, the cost of time, manpower, and material resources is very large, and the resistance encountered within existing traditional organizations is also not small. Of course, the existence of problems cannot hinder the development of blockchain. The proposal and in-depth research of technologies such as simple payment verification, side chain, and lightning network protocols have provided ideas for solving the above problems.

⑺ Is the public welfare blockchain a gimmick or is it really useful? What problems can it solve?

Blockchain technology is still developing and improving, and data encryption coins are just blockchain applications. Version 1/0 is professional, although it is relatively mature, but its uses are not diverse enough. Technologies such as blockchain technology belong to blockchain application 2.0 and are currently expanding their main uses. Promoting the improvement of blockchain technology based on the popularization of commercial applications requires a process. After the hustle and bustle of virtual currency subsided, we found that more and more fields, companies and even government agencies are vigorously promoting the application of blockchain in traditional commercial uses. If this process continues for 3-5 years,

The sources and trends of supplies and services are difficult to truly record and track. Public institutionsThe management solution for public welfare data is centrally known. In the case of relatively limited supervision, even with data records, it is difficult to eliminate the insecurity of the masses. In addition, public welfare information data may be forged, which is also an area where blockchain technology database management cannot be improved. Traditional public welfare platforms cannot provide users with the feedback they really want. On the one hand, opaque information makes feedback a mere formality; on the other hand, the existing feedback mechanism cannot create a good user experience.

⑻ What exactly does blockchain refer to and what disciplines or fields does it involve?

What is blockchain? Blockchain applications mainly include Internet technology and information content encryption algorithms, combined with appropriate rules and systems, to form a reliable system software infrastructure. The infrastructure here can be interpreted as the online environment. What does this trust mean? Database encryption methods can be divided into symmetric encryption algorithms and symmetric encryption. Symmetric encryption has higher security but slower response speed. The elliptic curve encryption technology used in blockchain technology is the fastest method among non-asymmetric encryption algorithms. Therefore, the encryption algorithm of blockchain technology is very powerful and it can ensure the uniqueness of the customer's identity. In addition, the information in blockchain technology is also protected by data encryption and is difficult to forge.

The blockchain system avoids the above three problems. The behavior of each node is different from other nodes. The behavior of the node is determined by the program in advance. The regulations are stipulated, and the encryption algorithm ensures that every connection point cannot violate the regulations. This is the connotation of grassroots democracy in the system. Blockchain applications are generally used to build trading software, and it is necessary to ensure that the transaction information content is authentic, valid, traceable and cannot be tampered with. Each transaction information is verified and stored in a zone, and the blockchain information is encrypted through hashing technology to ensure that the information cannot be forged. This blockchain forms a transmission chain in chronological order. Each node has complete blockchain information. If the information content of some nodes is destroyed, the blockchain information will not be affected. This type of archival information method is called a distributed ledger.

In such a distributed ledger of blockchain technology, the actual operation of adding a new record and linking it to all nodes must be carried out according to certain rules, otherwise nothing will be true and effective. . This standard is the consensus mechanism of blockchain technology. In essence, a fair and equitable consensus mechanism should allow all nodes to improve the blockchain. When the contents of the added blockchains are different, they should be negotiated according to certain standards until the contents of a certain blockchain are accepted, and then all nodes will copy this blockchain. Instead of equalizing the amount, not all nodes can be added to the blockchain. Instead, a point eligible to be added to the new server block is selected based on certain criteria and the blockchain information added by the node is copied. Blockchain technology uses the latter, and since the election rules are open and transparent, the competitionThe selection ceremony will become a competition process.

⑼ What is blockchain technology and how does it change business and financial models

Blockchain technology is a distributed ledger technology that allows Multiple participants work together on a decentralized network to maintain a secure, transparent and immutable record. Blockchain technology was originally designed for the digital currency Bitcoin, but is now widely used in many other fields.

The core features of blockchain technology include:

Decentralization: Blockchain has no central control agency, and data is distributed on various nodes in the network, which makes it decentralized. The centralization feature reduces the risk of single points of failure.

Transparency: Transaction records on the blockchain are public to all participants, and anyone can view these records. This helps increase trust and reduce the risk of fraud.

Immutable: Once a transaction is recorded on the blockchain, it cannot be easily modified or deleted. This guarantees data integrity and security.

Smart contracts: Transactions on the blockchain can be automatically executed to implement "smart contracts", which automatically execute corresponding operations when specific conditions are met. This helps simplify complex business processes and reduce costs.

Blockchain technology has had a profound impact on business and financial models, which is mainly reflected in the following aspects:

Reducing costs: Blockchain technology can reduce intermediary links and reduce costs. transaction costs and operating costs. For example, by adopting blockchain for cross-border payments, remittance fees can be significantly reduced.

Improve efficiency: The automation and smart contract features of blockchain technology help improve the efficiency of business processes, reduce manual intervention, and reduce error rates.

Enhance trust: The transparency and non-tamperability of blockchain technology help to establish a reliable trust system, reduce the risk of fraud, and provide better protection for business activities.

Innovative business models: Blockchain technology has spawned many new business models, such as decentralized finance (DeFi), digital asset trading, supply chain finance, etc. These new business models have brought disruptive changes to existing industries.

In short, blockchain technology, as an emerging technical means, is gradually changing the landscape of business and finance. With the continuous development of technology and the in-depth promotion of applications, blockchain is expected to have a more extensive and far-reaching impact in the future
