A. What kind of document is the China Blockchain Technology and Application White Paper?

This is a research report document and does not have any legal effect, it is just a suggestion.
The founding meeting of the China Blockchain Technology and Industry Development Forum and the first developer conference were held on October 18. The meeting released the "China Blockchain Technology and Application Development White Paper".
The "White Paper" summarizes the current status and trends of blockchain development at home and abroad, analyzes the technology applications in multiple application scenarios including finance, supply chain, culture and entertainment, intelligent manufacturing, social welfare, education and employment, and points out the regional The core technology path of blockchain and the direction and process of future blockchain technology standardization. (Reprinted from China Business Network)
The scope of blockchain application is theoretically very wide, but now blockchain is still in an early stage of development. Ethereum is mainly a smart contract platform; DECENT is a distributed content publishing platform.

B. How to identify the authenticity of a blockchain white paper

In the currency circle, there are many stories of getting rich by relying on a white paper and air coins. The digital currency industry based on blockchain technology is very hot. In this industry, the most indispensable thing is leeks and people who want to cut them. The proliferation of air coins has given rise to a new industry - "blockchain white paper ghostwriting".

Currently, there are a large number of "blockchain white paper ghostwriting" businesses on the market. In addition to Taobao, there are more than 100 shops engaged in blockchain white paper writing business on Zhubajie.com. Some stores claim to be able to conduct overseas advertising and even create project information on Wikipedia. The addresses of such stores are basically first-tier cities such as Beijing, Shanghai, Guangzhou and Shenzhen, and most stores support on-site negotiation of transactions. People in the blockchain industry said that many ghostwriting white paper routines are basically the same and are not particularly difficult. “There are standard templates for everything, and a lot of it is ready-made.”

These white paper ghostwriters are targeting a weak point in today’s blockchain market: most entrepreneurs don’t understand the issues surrounding blockchain What content should be included in the formal white paper of chain technology has become the reason to support the entire black production line.

Taobao’s actions obviously only cleaned up a very small part, and these “magic hands” cleverly avoided surveillance. When Gray Production Circle asked a Taobao merchant who had communicated with him before why he could not search for his store, the other party said that he could enter by clicking on the link he sent.

The irony is that these white paper ghostwriters who are waging a "guerrilla war" with Taobao are pure scams. The Gray Industry Circle learned from a ghostwriter that most of the writers behind these "Taobao white papers" are ordinary copywriters. Not only do they not understand blockchain technology, they can't even write code, but they claim that they "There's logic, too."

An insider who wrote a blockchain white paper even directly told the gray industry circle: "If you have an idea, give me an idea. If you don't have an idea, give me an outline. You don't have to give me an outline." I can also go in one direction, weLet me make a logical white paper for you. ”

So, how should we stay vigilant about “white papers”? The projects are unrealistic, the content is obscure and difficult to scrutinize, they are copied to attract popularity, and the team’s strength is infinitely exaggerated.

For ordinary people As far as capital is concerned, blockchain represents the ability to make quick money. The gathering of summits, celebrity platforms, and even the attendance of aunts have pushed the blockchain into wave after wave, but we must believe that under the supervision of multiple parties, , valuable blockchain project white papers can be truly implemented and serve the society.

The Xueshuo Innovation Blockchain Technology Workstation under Lianqiao Education Online is the School Planning, Construction and Development Center of the Ministry of Education of China The "Smart Learning Workshop 2020-Master's Degree Innovation Workstation" launched is the only approved pilot workstation for "Blockchain Technology Major". The professional station provides students with diversified growth paths, promotes the reform of professional degree research, production, learning and research integration training model, and builds application A comprehensive and comprehensive talent training system.

C. What signals does the blockchain 3.0 era give us?

In 2020, blockchain was included in the “new infrastructure” by the country In the category, at least 7 provinces have introduced blockchain support policies. In the same year, blockchain technology is gradually moving from concept to implementation, and application scenarios are blooming. Various industry applications of "blockchain" have become a continuous trend of blockchain. A sign of maturity.

The development status of "blockchain" in 2020

In 2020, the new coronavirus epidemic swept the world, and the uncertainty of world economic development increased significantly. Governments and enterprises of various countries Explore 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.

Currently, 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 good momentum of "shifting from reality to reality".

In order to avoid turning from reality to virtuality, in addition to continuing to crack down hard In addition to speculative behavior, it is also necessary to 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.

< p> 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, ranging from insurance, real estate, and commercial department stores. , security equipment, packaging materials, telecommunications operations and other 39 fields. In the blockchain information service registration list released by the National Internet Information Office, there are 45 blockchain projects of listed companies.

Among them, Finance is the most explored scenario among blockchain technology application scenarios, and there are 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, domestic projects have been filed Among the blockchain information services, the number of projects in the financial (including supply chain finance) field ranks first, accounting for up to 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 clarified the development ideas based on the alliance chain, focusing on serving the real economy and optimizing public services, and the direction of industrial development has become clearer. At this stage, the confidence of the majority of practitioners in blockchain continues to improve, and the long-term strategic value of blockchain is generally recognized.

What is the prospect of “blockchain” in 2021?

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

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

The core value of blockchain for the real economy is to promote efficient collaboration between upstream and downstream industries and improve the efficiency of industry-finance integration. In the early stages of development, the blockchain application model mainly focused on the storage of documents, contracts, etc. At this stage, blockchain industry applications are gradually moving towards automated collaboration and value interconnection such as government data sharing, supply chain 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 underlying technology and platformThere are four parts: 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 have accounted for half of all applications. Others, such as government affairs and people's livelihood, have become the future of manufacturers. Key layout areas are about to experience explosive growth.

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

D. What does the white paper in the blockchain refer to?

What does the white paper in the blockchain refer to? Just like the white paper issued by the state, it is the same principle.

E. How to write a blockchain project white paper

White Paper (English: White Paper) usually refers to an authoritative report or guidance text used to explain, solve or make decisions . The white paper has applications in both government and B2G markets. It can be seen that the white paper is more of an official document and pays attention to seeking truth from facts. When Satoshi Nakamoto wrote the white paper, it was to give Bitcoin seriousness and authority. But there is a difference between a blockchain project’s white paper and an official government document. It is more like a company’s business financing plan. The content that should be included in an enterprise's business financing plan is also introduced in the blockchain project white paper, such as project introduction, team introduction, technology introduction, business model, financing amount, etc.
The white paper of a blockchain project generally contains the following four aspects (of course, the specific expression methods are different):
Abstract, design principles and concepts, specific project implementation plan, and project prospects
>A blockchain projectThe white paper showcases the project and shows the market its business model, technical strength, team capabilities, development vision, etc. This is a very important basis for investors to judge the quality of this project. It is also a comprehensive display of the strength of the blockchain project team. For investors, the white paper of a blockchain project can provide most of the information about the project, thereby helping them make valuable investment decisions. For the project team, writing a blockchain project white paper can also lay a very good foundation for crowdfunding the project.
The essence of the white paper is the entrepreneur’s financing promotion to potential investors, so it needs to be as detailed and detailed as possible.
Corporate vision, core team, market and problems, products and solutions, about Token, fund use statistics and forecasts, and development planning.
Investors are looking for:
Company information, prototype, blockchain application, team strength, strategic gap, competition, planning path, research basis, format.
Considering the level of detail with which investors browse white papers, the content of the white paper should not contain content that may cause investors to worry. Therefore, founders need to be very careful to ensure that they provide as much information as possible, but also that the information is simple, easy to understand, supported by research or statistics, and well presented.
The Xueshuo Innovation Blockchain Technology Workstation under Lianqiao Education Online is the only approved "Blockchain Technology Professional" pilot of the "Smart Learning Workshop 2020- Xueshuo Innovation Workstation" launched by the School Planning, Construction and Development Center of the Ministry of Education of China. workstation. The professional base is based on providing students with diversified growth paths, promoting the reform of the training model integrating professional degree research, production, and research, and building an applied and compound talent training system.

F. How do you think the white paper of the blockchain project is reliable? Or is there a project white paper that I can refer to?

I personally think it is a better white paper example: Penta (called "Panta Network" or "PNT") is the underlying basic chain of the next generation blockchain value Internet. and protocol, aiming to realize three major connections (chain-to-chain connection, chain-to-centralization connection, off-chain and on-chain value connection) based on 5 dimensions (subject, trust, value, circulation and scenario), and provide This has formulated 10 specific core technology routes to make the blockchain world interconnected and inclusive. The main content is divided into four parts: 1. The philosophical basis of the Vatican Network; 2. The connection of the five dimensions; 3. The interaction of worlds; 4. Application fields.

G. What is blockchain and what are its uses? Will it become a new trend?

Three questions about blockchain (economic hot spots)

In recent times, relevant Bitcoin news is very eye-catching, and blockchain has also become popular. In the capital market, the stock prices of various blockchain concept stocks rise and fall like a thrilling roller coaster. It can be seen from the responsive capital market that blockchain is on the forefront and has received great attention from all parties.

"BlockChain technology is essentially a database technology, specifically a ledger technology. The ledger records the asset changes and transactions of one or more accounts. It is actually a database with the simplest structure. The running accounts we usually write down in small notebooks and the statements sent by the bank are all typical ledgers. "Wang Jun, chief researcher of Tencent Financial Technology Think Tank, said that security is a major feature of blockchain technology, which is mainly reflected in two aspects: first, the distributed storage architecture, the more nodes, the higher the security of data storage; second, Its tamper-proof and decentralized ingenious design makes it difficult for anyone to modify data without following the rules.

Take online shopping transactions as an example. The traditional model is for buyers to purchase goods and then transfer the money to a third party. The payment institution is an intermediary platform. After the seller delivers the goods and the buyer confirms receipt, the buyer notifies the payment institution to transfer the money to the seller's account. The transaction model supported by blockchain technology is different. Buyers and sellers can trade directly. There is no need to go through any intermediary platform. After the buyer and seller trade, the system publishes the transaction information in the form of broadcast. All hosts that receive the information record the transaction after confirming that the information is correct, which is equivalent to all hosts having made data for this transaction. Backup. Even if there is a problem with a certain machine in the future, it will not affect the data record, because there are countless machines as backup.

When it comes to blockchain, many people associate it with Bitcoin. At the same time, many people even equate blockchain with Bitcoin. He Fei said that Bitcoin is a representation of blockchain, but blockchain is not the same as Bitcoin. Blockchain is the underlying layer of Bitcoin. Technology and infrastructure, and Bitcoin is a successful application of blockchain, but it does not mean that blockchain can only be applied to Bitcoin.

What is the use of blockchain?

It can solve the pain points and difficulties in many fields such as finance, public welfare, supervision, and anti-counterfeiting, but there are many applicable conditions

Financial services are the first application field of blockchain technology. Using blockchain Technology can solve pain points in many fields such as payment, asset management, and securities.

Take the payment field as an example. The cost of reconciliation, clearing, and settlement between financial institutions, especially cross-border financial institutions, is relatively high. , involving many manual processes, not only results in high costs for the user end and the backend business end of financial institutions, but also makes it difficult to carry out small payment business. The application of blockchain technology can help reduce reconciliation costs and disputes between financial institutions solve the cost and significantly improve the processing efficiency of payment business. In addition, the cost and efficiency advantages brought by blockchain technology to the payment field enable financial institutions to better handle small-amount transactions that were previously considered unrealistic due to high costs. Cross-border payments help achieve inclusive finance.

For example, in order to solve the problem of high reconciliation costs among financial institutions, in August 2016, WeBank and Shanghai Huarui Bank launched Weilidai This is also the first domestic banking alliance chain application scenario running in a production environment. Kaixiang Zhang, chief architect of WeBank’s blockchain, believes that the traditional “batch file reconciliation” model has long been unable to solve the cost high problem, which is exactly where blockchain technology comes in. Subsequently, Luoyang Bank and Changsha Bank also successively connected to the inter-institution reconciliation platform. Through blockchain technology, they optimized the inter-institution reconciliation process in the micro-loan business, achieving quasi-real-time reconciliation, improving operational efficiency, and reducing operating costs. Target. Up to now, the platform has been running stably for more than a year, maintaining zero failures, and the number of real transactions recorded has reached tens of millions.

In the field of public welfare, blockchain technology also has great potential. Ant Financial's first application scenario involving blockchain was public welfare, helping a group of hearing-impaired children obtain a donation, and then using blockchain technology to promote public welfare to be more open and transparent. Hu Danqing, senior product expert at Ant Financial Technology Lab, said: "The blockchain charity platform is like us building a post office on the Internet specifically for mailing funds. Every money donated by users, we will package it into a The package is delivered through the blockchain platform. Every time it passes through a node, we will stamp a postmark and finally deliver it to the recipient. This ensures that every money donated by users is transparent, traceable, and difficult to tamper with. ”

Blockchain technology can play a big role in combating counterfeit goods. Hu Danqing introduced that Ant Financial uses blockchain technology to trace the origin of authentic products. At present, there are some overseas shopping products from Australia and New Zealand, such as milk powder. You can use Alipay to scan the products to know whether they are genuine. "Unlike the previous self-entered product information by merchants, blockchain allows multiple 'bookkeepers' to complete accounting fairly, independently, and non-repudiation."

For financial supervision, blockchain Technology can also play a role. The "Financial Blockchain Underlying Platform FISCO BCOS White Paper" released by the Financial Blockchain Cooperation Alliance (Shenzhen) in 2017 believes that blockchain provides financial regulatory agencies with consistent and easy-to-audit data. Data analysis can supervise financial businesses faster and more accurately than traditional audit processes. For example, in an anti-money laundering scenario, the balance and transaction records of each account are traceable, and no aspect of any transaction will be out of sight of supervision, which will greatly enhance anti-money laundering efforts.

Some people in the industry believe that blockchain 1.0 is mainly aimed at digital currency; blockchain 2.0 is aimed at smart contracts and can be applied in the financial market; blockchain 3.0 will be applicable to more scenarios, and even Create a "blockchain era".

He Fei believes that blockchain can indeed solve the pain points and difficulties in many fields, but blockchain is not a panacea and has many applicable conditions.

For example, the decentralized nature of blockchain technology is suitable for scenarios involving multi-party participation. If it is only unilateral or bilateral participation, it will be of little value. Since each node needs to be checked, blockchain technology is not suitable for high-frequency trading activities.

For another example, blockchain emphasizes openness and transparency and is not suitable for scenarios with particularly high data privacy requirements.

Will blockchain become a new trend?

The technology is not yet mature, so be wary of concept hype.In particular, it is necessary to distinguish between technological innovation and fund-raising innovation. Blockchain cannot be used for the sake of blockchain

The concept of blockchain is so popular, will it become another "Internet +" in the future?

In recent years, the development ecosystem of blockchain has gradually been improved and enriched. Industry insiders believe that with national policy support, widespread attention and financial support, blockchain technology can achieve gradual and stable progress. Although the upside prospects of blockchain technology are broad, we must remain calm about this.

“Although blockchain is very popular right now, we still believe that it is still in a very early stage.” Hu Danqing said that there is currently false enthusiasm in the blockchain concept, and it is not that the technology is used to solve the problem. The real problem is that the focus is on raising funds to make money and hyping valuations. In particular, most of the so-called ICOs (Initial Coin Offerings) that are so popular are innovations in fundraising tools and have nothing to do with technological innovation.

Blockchain technology can indeed create great value, but some risks cannot be ignored.

“Blockchain technology is not yet mature, and its application scenarios are relatively limited. We should be more wary of the concept of capital market speculation.” He Fei said that behind the blockchain boom, there will inevitably be some gimmicks and speculation. Companies that do not really carry out business, but just try to make a profit in the capital market and leave. We must be careful to prevent the occurrence of "bad money driving out good money", causing institutions that really want to do business to withdraw from the market, affecting the development of blockchain technology. application.

Hu Danqing suggested that for the current blockchain craze, regulatory authorities should intervene more proactively, distinguish between technological innovation and fund-raising innovation, and encourage government organizations, credible experts, and industry participants to jointly help the public Identify and comprehensively curb fund-raising innovation in the name of blockchain, so that the actual controller of ICO must bear responsibility for the fund-raising behavior. "The basis for judging whether it is technological innovation or fund-raising innovation is actually very clear, that is, whether it starts with trust and whether it creates actual value by solving the trust problem."

Better promotion and use of blockchain technology in the future , it is necessary to continue to improve infrastructure and strengthen the formulation of relevant laws and policies.

Wang Jun believes that there is still room for optimization and improvement in core blockchain technologies such as consensus algorithms; on the other hand, the processing efficiency of blockchain is still difficult to reach that of some high-frequency application environments in reality. Require. At present, the mainstream blockchain technology platforms all originated from abroad. Domestic blockchain technology service providers must patiently start from the bottom development, achieve independent and controllable technology, and strive to lead the development of global blockchain technology. Enterprises with blockchain application scenarios must actively embrace new things and scientifically evaluate their on-chain needs. They cannot use blockchain for the sake of blockchain.

He Fei believes that the government can introduce relevant policies to guide companies that are interested in participating in the research and development and application of blockchain technology, and at the same time clarify some suitable application scenarios of blockchain and areas encouraged by the state.

The "China Blockchain Technology and Application Development White Paper 2016" recommends that government departments at all levels learn from the advanced practices of developed countries and regions, combine the development of my country's blockchain technology and applications, and promptly introduce blockchainTechnology and industrial development support policies focus on supporting key technology research, major demonstration projects, "mass entrepreneurship and innovation" platform construction, system solution research and development, and public service platform construction. At the same time, it is recommended that key domestic enterprises, scientific research, universities and user units strengthen cooperation to speed up research on core key technologies such as consensus mechanisms, programmable contracts, distributed storage, and digital signatures.

If it can bring money to the enterprise, it will become a hot topic.
