A. What is blockchain

What is blockchain? What changes will it bring to your future life?

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

Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of cryptographic methods related to each other. Each data block generated contains a batch of Bitcoin network transaction information, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

In fact, the original English version of the Bitcoin white paper does not appear in the word blockchain, but uses chain of blocks. In the earliest Chinese translation of the Bitcoin white paper, chain of blocks was translated into blockchain. This is the earliest time when the Chinese word "blockchain" appeared.

The Cyberspace Administration of China issued the "Blockchain Information Service Management Regulations" on January 10, 2019, which will come into effect on February 15, 2019.

In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-transformable. Fake distributed ledger.

So in conclusion, this is undoubtedly a new technology that changes life. In the future, the production activities of the entire society will be carried out with blockchain as the underlying logic. Many things We all have it at our fingertips, and with the integration of artificial intelligence and big data, we can easily handle things that may seem cumbersome now, such as some securities market transactions and intelligent matching of financial management activities.

To put it simply, blockchain is a network computing center that integrates people, property, machines, and goods, and packages them into a whole; putting it on an infrastructure to run.

B. Blockchain technology and applications: a technological revolution in the future

Blockchain technology originated from "Bitcoin: A Peer-to-Peer Electronic Cash" proposed by Satoshi Nakamoto System", where "block" means that each information block contains a timestamp. Information blocks containing timestamps are connected to each other, and the chain of information blocks formed is a "blockchain".

Blockchain is a technical solution that collectively maintains a reliable database in a decentralized and trustless manner. From a data perspective, blockchain is a distributed database in which a single node or multiple nodes cannot intentionally change data records. Its distribution is reflected in the distributed storage and distributed recording of data. From a technical point of view, blockchain technology is an emerging technological achievement after the integration of multiple technologies. After the development and improvement of multiple technologies, it forms a more efficient data recording, storage andway of expression.

C. What is blockchain? If you understand these 9 questions, you will understand

What is blockchain? If you understand these 9 questions, you will understand
What is blockchain? What can blockchain do? How to make money with blockchain? I believe that many netizens are confused when faced with this new term. So how can we better understand blockchain and make this new technology available to us? The author has collected nine very common questions from the Internet. I hope that after reading this article, you will have a clearer understanding of blockchain.

Nearly omnipotent blockchain technology
Simply put, blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. Its core is distributed data, and the result is "decentralization." Blockchain technology can be applied to many scenarios in our lives. Next, let’s take a look at the analysis of blockchain technology!
1. Technology is a double-edged sword. While you are still using your mobile phone to play games, others are already using their mobile phones to make money every month! I want to try Jiaerwu Wuyi Wuba Lingyi Lacquer to make your mobile phone no longer a toy!
Just like nuclear energy is a physical technology, blockchain is an underlying technology at a technical level.
Nuclear energy can be used for atomic bombs and nuclear power generation. Similarly, blockchain can be used for the management of industries and life elements, which may make society more stable, or it may be used by bad guys as the fastest way to commit crimes. .
2. Talking about technical value apart from the application level is muddying the waters
As the underlying technology, blockchain has its application level and negotiation methods. Currently, some people talk about blockchain in terms of business models, some in terms of hardware, and some people talk about blockchain in terms of power distribution. It is gradually becoming clear in the market that blockchain is used in the design of technology combinations and business models, from hardware to software to business model to financial design and many other aspects. But not every blockchain can issue coins, and not every blockchain should issue coins.
3. Technology is decentralized, but the application is not necessarily
Blockchain technology is decentralized, but it can be decentralized or not in upper-layer applications. If it is applied to things, industries and projects that cannot be decentralized, it is not decentralized; if it is used to things where everyone can participate universally and have equal authority, then it can be decentralized.
Including coins on the blockchain, if a country adopts legal digital currency, the coins on the blockchain can also be centralized. The blockchain that supports the operation of Bitcoin is decentralized, but the alliance chain usually has one or more enterprises as the core control alliance, which becomes centralization.
Technical bookWhat kind of business and what kind of political ecology can be supported by the body and technology are completely different things.
4. What kind of people use what kind of tools
As a powerful tool, blockchain is powerful not only because of technology, but also because many talented people have invested in it. field, causing the energy of this technology to be amplified. As for whether the power of blockchain benefits society or cuts leeks? It is possible to make the world more turbulent or to make society more harmonious and beautiful.
On the positive side, more kind-hearted people will come in and reach more consensus, and there will be more legislation, restrictions and norms at the national level, which will ultimately allow us to use this technology to give more people opportunities; on the negative side, In other words, it is possible that more greedy and unethical people will come in to divide the wealth, and it is even possible that people in some countries and regions will use this new technology to commit crimes and terrorism.
5. Blockchain promotes the globalization of civilians
Under the blockchain, the global connection space is closer. The 6-degree space will become 5 degrees or even 4 degrees in the future. Blockchain can inspire The growth of various communities. The globalization of interest groups will become inevitable, and there will be various international communities and summits in the future.
6. Blockchain facilitates co-creation
For example, in the past, the connection between international singers and ordinary people had to go through several barriers, including record companies, agents, sales channels, etc. In the blockchain era, international singers publish their songs under blockchain technology. Everyone has the possibility to become a partner of an international singer, write songs for the international singer, or purchase Tokens to obtain dividend rights from distribution proceeds, etc., and enjoy records. Proceeds from distribution and downloads.
7. Trust will become convenient and low-cost
The combined effect of artificial intelligence, big data and blockchain can resolve disputes at the factual level. The tamper-proof nature of the blockchain allows hundreds or even tens of thousands of machines to maintain the same data and encrypt it. Basic facts will be trustworthy. On this basis, the corresponding contracted and authorized information cannot be changed. Replace manual systems with machines, breaking the loopholes in manual operations, the possibility of cheating and even corruption, so that everyone's information can be confirmed to be authentic and trustworthy.
On this basis, if the trust level of the business system is good, trust between people will be enhanced in the process of implementing the designed system.
8． Interaction leads to creativity, and creativity generates income
Blockchain is a comprehensive ledger. Some exchanges are just ideas and creativity at the moment, but they may be the starting point of a certain career or even industry in the future. In the previous accounting system, there may not be value. However, under blockchain technology, values ​​that are not yet seen can be recorded. If this leads to products, creative people can benefit. Various human activities may be valuable, creative, and worthy of recording.
Extended from this, a better application of blockchain can record creative related models, introduction of business opportunities, etc., and put valuable things in an ecosystem. BlockchainChains can create new ways of cooperation.
9. There will be more legal supporting facilities in the future
The world of blockchain is not a disorderly world. Technology will be used by people, and people are rational.
Records can resolve various factual disputes, and can also cause more issues such as authorization rights, patent and creative copyright management, and many other issues. In the future, there will be more legal support, which can not only standardize and manage service consumption and life, but also avoid related risks and problems, avoid and combat crime

D. What is blockchain and how was it born? What are the types of blockchain?

If you want to understand blockchain, you must first understand the basic structure of the program. Everything we see on the Internet is constructed through computer language. There are many kinds of computer languages, but the most basic characters that make up the language are codes, and blockchain technology is a way of applying codes, which is different from traditional centralization. The difference between the models is that the blockchain has the characteristics of immutability, privacy, security, and consensus.

There are many application scenarios for blockchain. The most successful case so far is Bitcoin, followed by electronic invoices, cross-border payments, etc. Based on the interoperability of data, it is impossible to With characteristics such as tampering, it can also be used to save some important data. As long as this data uses blockchain technology as the underlying technology, it can never be destroyed and will be saved forever. No person or institution has the ability to modify or delete it. In addition, there are certain intersections between blockchain payment and education, medical care, credit reporting, automobiles, transportation and other fields. It is a technology, not a certain product, so there is only one type of it, but with the application As the scene changes, its role is also different. It can be integrated with existing scenes in almost any field and then derive other applications.

E. What is digital currency blockchain

1. Blockchain is a ledger that records digital currency transactions
Take Bitcoin as an example. It has no physical form. Instead, it exists in a dedicated ledger. All Bitcoin transactions are recorded in the ledger. Through the transaction records, we can calculate the number of Bitcoins owned by each user. If a person owns Bitcoin, it means that transaction records related to him can be found in the ledger.
The ledger mentioned here is a piece of software, which we can download from the official Bitcoin website, and the underlying technology used in this software is the blockchain. To facilitate understanding, we usually say that the blockchain is the ledger.
The reason why blockchain is used as the underlying technology of the ledger is to achieve the decentralization of digital currency. It can be said that the starting point for a series of problems encountered by digital currencies and the solutions provided comes from decentralization.
2. Blockchain is a technology that ensures the safe use of digital currencies. Everyone knows that blockchain technology has two major characteristics: encryption and non-tamperability, which can reduce the probability of errors during the use of digital currencies. reduced to 0. Since digital currencies have higher requirements for encryption, blockchain technology must be used to support them. At present, not onlyMany industries in our country are using blockchain technology, and even many foreign countries are also actively using blockchain technology.
[Extended information]
Blockchain is the underlying technology of digital currency, and Bitcoin is the first successful application of blockchain.. To understand this problem, we must first recognize the facts: not all blockchains require Issuing digital currency, currently our country strongly supports "coinless blockchain". Generally speaking, public blockchain, that is, public chain, needs to issue tokens as "rewards" to motivate users and maintain system operation, while ordinary blockchain , often called a consortium chain, can or cannot be issued. Private blockchains are mostly used for company internal audits and generally do not need to issue coins. The following is a detailed explanation of the differences between the three blockchains:
1. Public block Chain: A blockchain in which anyone in the world can read and send transactions for validity confirmation, and anyone can participate in its consensus process. Bitcoin and Ethereum are typical applications of public blockchains. Public blockchains are a global Distributed blockchain, blockchain data is open, user participation is high, and it is easy to produce network effects, easy to apply and promote. Therefore, this kind of blockchain operation relies heavily on the incentive mechanism, Bitcoin Tokens such as Ethereum and Ethereum are used as "rewards" for incentives, so public chains need to issue tokens to maintain their own development and ecology.
2. Community Blockchain (Alliance Chain): It means that the participation of nodes in the blockchain is selected in advance. There are usually good network connections and other cooperative relationships between nodes. The data on the blockchain can be open It can also be internal. For partial distribution, we can regard it as "partial decentralization". Each alliance in the chain has its own centralized management. For example, R3CEV of more than 40 banks is a typical alliance chain. Chains usually do not require a lot of money, but there are also individual alliance chains that choose to send money to motivate members within the alliance to contribute, so there are no restrictions on the chain.
3. Private blockchain: refers to a node with a limited scope of participation, such as a specific organization’s own users, strict permission management for data access and use.. Write permissions in a completely private blockchain It is only in the hands of the participants, and the read permission can be opened to the outside world or restricted to any extent. It is currently mainly used for internal audit work of the company. Therefore, the private chain does not need to issue currency, and it does not have the characteristics of decentralization. It is a kind of centralization management mechanism.

F. What exactly is the blockchain?

What exactly is the blockchain? In essence, blockchain is a distributed, decentralized network database system that will make the storage, update, maintenance, and operation of data different. Blockchain has four indispensable core technologies, namely: distributed storage, consensus mechanism, cryptography principles, and smart contracts.

Then let’s talk about how blockchain is different from traditional data processing to help everyone understand what blockchain is and give everyone a general understanding of blockchain. recognizeKnow.

1. Data storage in blockchain: block chain data structure

In terms of data storage, blockchain technology utilizes "block chain data structure" To verify and store data.

What does the blockchain structure mean? Everyone has seen an iron chain, with one link within another. In fact, each link can be regarded as a block, and many links are linked together to form a blockchain.

How does this so-called "iron chain" store data? To put it simply, the difference between blockchain and ordinary stored data is that on blockchain, the data in the next block includes the data in the previous block.

Take reading as an example: when we read a book, we finish page 1, then page 2, page 3...
What about in the blockchain? If each block is marked with a page number, then the content on page 2 contains the content on page 1, the content on page 3 contains the content on page 1 and page 2...Page 10 contains The content of the first 9 pages is such a chain nested layer by layer. In this way, the most original data can be traced back. This is the traceability of the blockchain.

The "blockchain data structure" of blockchain makes it traceable, which is naturally suitable for many fields, such as: food traceability, drug traceability, etc. In this way, the probability of tainted milk powder, fake vaccines, and fake and substandard food incidents will be greatly reduced, because once a problem occurs, through traceability, we can clearly know which link caused the problem, and accountability and recovery will be clearer.

2. Data update in the blockchain: distributed node consensus algorithm

In terms of data update, blockchain technology uses the "distributed node consensus algorithm" to Generate and update data.

Every time a new block is generated (that is, when data is updated), an algorithm needs to be used to obtain the approval of more than 51% of the nodes in the entire network to form a new block. To put it bluntly, it is a vote, and it can be generated if more than half of the people agree, which makes the data on the blockchain non-tamperable.

Why do you say that? Let’s make an analogy: we compare the blockchain to a ledger, because it records data. In the traditional world, the bookkeeping power lies with the bookkeeper, and the ledger belongs to the bookkeeper alone. So in the blockchain, everyone owns this account book. If you want to update the account, you must vote. Only if more than half of the people agree can you update the account data.

In this process, we will involve several terms: distributed, node, consensus algorithm. These terms are actually very easy to understand:

Everyone accounting (i.e.Everyone has a ledger, and the ledger is scattered in everyone's hands), which is the so-called "distributed";

The accounting method that everyone discusses, votes for, and unanimously agrees on is the so-called "consensus algorithm" ";

Every person involved in accounting is a so-called "node".

3. Data maintenance in blockchain: cryptography

In the data maintenance stage, the difference of blockchain is that it uses cryptography to Ensure the security of data transmission and access.

The cryptographic principles applied in the blockchain mainly include: hash algorithm, Merkle hash tree, elliptic curve algorithm, and Base58. These principles actually ensure data security on the blockchain through a series of complex operations and conversions.

4. Data operations in the blockchain: smart contracts

A smart contract is a commitment agreement defined and automatically executed by a computer program. To put it bluntly, it is executed with code A set of transaction rules, similar to the current automatic repayment function of credit cards. If you turn this function on, you don't have to worry about anything. The bank will automatically deduct the money you owe when it expires.

The outstanding advantage of smart contracts is that they largely avoid a series of problems caused by trust.
Many of us have encountered the situation of being borrowed money: a friend who is short of money borrows 2,000 yuan from you and promises to pay back the money after the salary is paid next month, but next month he finds other excuses. Also, dragging this matter around would be pointless. We didn't have much money, but we were still friends. Even though you were depressed, let it go.

Then, with the smart contract, he can no longer default on his debt, because in the smart contract, once the terms in the contract are triggered, the code will automatically execute, whether he wants it or not, as long as he sends Once you have earned your salary and have money in your account, he has to pay you back.

To summarize the contents of this section, there are four indispensable core technologies in the blockchain, namely: distributed storage, consensus mechanism, cryptography principles, and smart contracts.

We can understand it this way: distributed storage corresponds to the data storage stage, the consensus mechanism corresponds to the data processing and update stage, cryptography corresponds to data security, and smart contracts correspond to data operational issues.

G. What is blockchain technology? What exactly is blockchain?

In a narrow sense, blockchain is a way to block data in chronological order. A chained data structure composed of sequential connections, and a cryptographically guaranteed 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.A new distributed infrastructure and computing method that ensures the security of data transmission and access and uses smart contracts composed of automated script codes to program and operate data.

[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 addresses this issue Four technological innovations:

1. Distributed ledger means that transaction accounting is completed by multiple nodes distributed in different places, and each node records a complete account, so they all Can participate in supervising the legality of transactions and can also jointly testify for them.

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 "minority of service"From the characteristics of "majority" and "everyone is equal", "the minority obeys the majority" does not entirely refer to the number of nodes, but can also be computing power, the number of shares, or other characteristics that computers can compare. "Everyone is equal" is When the nodes meet 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 trusted The tamper-proof data can automatically execute some predefined rules and terms. Taking insurance as an example, if everyone's information (including medical information and risk occurrence information) is true and trustworthy, it would be very It is 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, their reliance on trusted data is It continues to increase. 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, it is mainly divided into policyholder risk management and insurance company risk supervision.< /p>

Blockchain-Network

H. Blockchain Encyclopedia: The Past and Present of Blockchain - Era 3.0

Blockchain 1.0 The representative of the era is Bitcoin, the representative of the 2.0 era is Ethereum, and the troubled times of various copycats and air coins. Blockchain 3.0 is a consumer-level blockchain that has truly entered commercial applications and physical applications after the troubled times. The typical symbol of this era is the emergence of tokens. Tokens have brought about changes in traditional business models and production relations. Tokens have moved from the digital world to the real economy and have begun to seek practical applications in various industries.

The pass has three elements, one of which is indispensable.

Pass: The pass can be circulated on a large scale in a network and can be verified anytime and anywhere; Certificate: As a proof of digital rights, the pass must It is a certificate of equity that exists in digital form. It must represent a right, an inherent and intrinsic value; value: the token must have economic value.

In this way, the "token" It is not difficult to understand the meaning of "economy". The token economy is a large-scale group collaboration based on tokens. It maximizes the role of tokens and allows every role that creates value to share value fairly and fully mobilize Participate in the driving force and form a self-organizing form.

Major changes in the blockchain 3.0 era

The token economy has laid the theoretical basis and technology for the large-scale application of blockchain Support, the future world will also change on a large scale because of this, including:

1. Fragmented investment, fragmented income, subverting the traditional way of doing business on the Internet. In the traditional Internet era, ordinary people do not It is possible to participate in the investment of a company, and blockchainThe emergence of it allows ordinary people to make fragmented investments in a large asset. Assuming that Alibaba originally adopted blockchain for fragmented investment, then all fragmented shareholders who invested in Alibaba would be able to reap a return on investment that has increased thousands of times today!

2. Break the money-burning model of the Internet and make everyone a winner. The free model of the traditional Internet is essentially to obtain a large number of users through free products to form monopolies and barriers, and then make profits through advertising and value-added services on this basis. In the blockchain 3.0 era, project income is redistributed by issuing tokens to attract more early investors and community users. As the number of users holding tokens increases, the value of the tokens will become higher and higher, and community users, investors, and projects can all benefit from it. In this way, the money-burning model of providing free services in the early days of the traditional Internet can also be improved, and everyone will become a winner.

3. Breaking down the traditional corporate organizational hierarchy, self-organization may become a future trend. In the blockchain 3.0 era, through the establishment of distribution and collaboration mechanisms through smart contracts, it can be more efficient and accurate than enterprises. All token owners will naturally form a community. Everyone has the same goal - "to promote the development of the project and make it a success". They are all members of the community, contribute to the community, promote the value-added of the token, and thus gain benefits together. profit. From a philosophical perspective, this new self-organizing community of freedom, independence, and equality must be the future trend. Gojoy blockchain e-commerce is a blockchain self-organized community. Every consumer is a token owner and a fragmented investor, so he is very happy to co-create and build Gojoy value.

Therefore, we can look forward to the era of great development of the blockchain 3.0 token economy, and the existing ones may be subverted. What we need to be prepared for is to work hard to embrace the blockchain. If you want to seize the trend of blockchain and understand how to transform into blockchain, please leave a message to communicate and we will take you to learn the blockchain professional certification course.

I. What is data blockchain (BlockChain)

Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. Blockchain is an important concept of Bitcoin.

It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of related data using cryptographic methods. Each data block generated contains a batch of Bitcoin network transaction information, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

(9) Extended reading of blockchain technology picture materials

Most public blockchain chains are limited by scalability. The biggest feature of blockchain technology is decentralization, which requires all ledgers in the network to handle the accounting process. Distributed accounting has high security, low misoperation rate, and has politicalgovernance neutrality and correctness.

However, while blockchain technology embraces these characteristics, it sacrifices scalability, cannot meet personalized supervision, and is slightly insufficient in protecting data privacy. Moreover, as the number of ledgers increases, the interaction delay will increase exponentially, which means that the more ledgers in the blockchain network, the higher the latency will be.

J. What should the phenomenon and application of blockchain look like

1. The revolution of blockchain

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

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

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

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

2. Blockchain+

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

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

In 2019, the scale of China’s blockchain industry alone reached RMB 1.2 billion. Data from the research institution Research and Markets shows that blockchain technology plays an important role in the telecommunications field.The value of the domain will surge from US$4.66 million in 2018 to US$993.8 billion in 2023. Against this background, 2020 will usher in multiple policy benefits.

1. Officials have included blockchain into the scope of new infrastructure and new technology infrastructure;

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

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

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

5. Jiangxi launched a blockchain service hall online;

6. Wuhan A special event for the transformation of blockchain technology scientific and technological achievements will be held;

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

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

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

3. Blockchain native applications

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

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

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

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

Therefore, blockchain native applications should be based on community and consensus, giving individuals a path to realize their value, and maximizing individual energy and creativity.The application ecology will eventually break the monopoly and form a decentralized free exchange network of value.

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

Native applications that truly conform to the spirit of blockchain should be grand and comprehensive in application model design, taking into account all online and offline value-creating behaviors of individuals for personalized use by individuals. , each individual’s areas of expertise are different.

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