『一』Does the country support blockchain?
As a new technology, blockchain is a new technology. Countries around the world have corresponding policies to support its development, with a wide range of radiation—— Judging from this year, more than half of the provinces and cities across the country have included blockchain in the 2020 government work report. In addition to first-tier cities such as Beijing, Shanghai, Guangzhou and Shenzhen, central and western cities such as Gansu, Ningxia, and Xinjiang have also joined the blockchain technology research and application camp. Developed cities in the east continue to play a leading role in technological research and application innovation; cities in the central and western regions adapt to local conditions and combine new technologies to accelerate digital economic transformation. Strong support - this year the Central Bank, the Ministry of Transport, the State Administration of Foreign Exchange, the State Administration of Radio, Film and Television, the Ministry of Justice, the Ministry of Agriculture and Rural Affairs, etc., have respectively proposed the use of blockchain technology to accelerate the development of applications in various fields. Many other provinces and cities have also continued to introduce new policies, most of which are special support policies for blockchain. It is expected to build more industrial parks and open up more government application scenarios. The direction is clearer - there are clearer details under the general direction of blockchain assisting the transformation and upgrading of traditional industries and empowering the digital economy. Application scenarios such as transportation, agriculture, intellectual property, and certificate storage have become the first batch of experimental directions. In terms of government affairs, it is an important breakthrough and has been implemented. Beijing City’s “innocent approval”, Jiangxi Province explores “blockchain + undocumented handling”, Fujian Province implements the “on-chain government affairs” project, and Gansu Province accelerates the construction of “Digital Gansu”. ”, Shandong and Hainan are all committed to e-government and other fields. It is foreseeable that the future blockchain e-government scenario is worth looking forward to. Legal basis: Article 3 of the "Blockchain Information Service Management Regulations" The Cyberspace Administration of China is responsible for the supervision, management and law enforcement of nationwide blockchain information services in accordance with its duties. The Internet Information Offices of provinces, autonomous regions, and municipalities directly under the Central Government are responsible for the supervision, management and law enforcement of blockchain information services within their respective administrative regions according to their responsibilities. Article 4 encourages blockchain industry organizations to strengthen industry self-discipline, establish and improve industry self-discipline systems and industry standards, guide blockchain information service providers to establish and improve service specifications, promote the construction of industry credit evaluation systems, and supervise blockchain information service providers Provide services in accordance with the law, accept social supervision, improve the professional quality of blockchain information service practitioners, and promote the healthy and orderly development of the industry. Article 5 Blockchain information service providers shall implement information content security management responsibilities and establish and improve management systems for user registration, information review, emergency response, and security protection. Article 6 Blockchain information service providers shall have technical conditions suitable for their services.

It should comply with relevant national standards and specifications. Article 7 Blockchain information service providers should formulate and disclose management rules and platform conventions, sign service agreements with blockchain information service users, clarify the rights and obligations of both parties, and require them to promise to abide by legal regulations and platform conventions.
『二』Application and analysis of blockchain in the field of government affairs
Blockchain has become a hot topic at the two sessions in 2020, in Sichuan, Fujian, Hunan, Hebei,The development of the local blockchain industry was mentioned at the local two conferences held in more than 20 regions including Jilin, Beijing, Chongqing, and Shenzhen. Judging from the content of the government work report, most local governments regard blockchain as a new growth point to assist industrial optimization and upgrading, smart city construction, and the digital economy. In particular, among the blockchain application scenarios mentioned in Beijing, Shenzhen, Shandong and other places, the government affairs field has become a flash point. According to incomplete statistics, as of now, more than 90 blockchain government applications have been completed or are under preparation.
『三』Government’s development of blockchain technology
With the further development of blockchain technology and the government’s elevation of the technology to a national strategic level, it has effectively accelerated and Promoted the comprehensive development and layout of blockchain technology. In the face of this epidemic, blockchain technology, while giving full play to its own advantages, cooperates with artificial intelligence, big data, Internet of Things, cloud computing and other technologies to play a role in government affairs management, supply chain finance, charitable donations, logistics and transportation, etc. It has produced huge effects and effects, which has brought blockchain technology to a higher level of attention. It has not only promoted the exploration and involvement of blockchain technology in various industries, but also enabled governments at all levels and central enterprises to The blockchain field is making full efforts and actively deploying! Next, let’s take a look at the recent related actions and plans of local governments and national functional departments in the field of blockchain! Legal basis: Article 9 of the "Regulations on the Establishment and Establishment Management of Local People's Government Organizations at All Levels". For the establishment, cancellation, merger or change of specifications and names of administrative agencies of local people's governments at all levels, the people's government at the same level shall propose a plan, which shall be approved by the next higher level. After review by the people's government organizational establishment management agency, it shall be reported to the people's government at the next higher level for approval; among them, the establishment, cancellation or merger of administrative agencies of local people's governments at or above the county level shall also be reported to the Standing Committee of the People's Congress at the same level for record in accordance with the law. Article 10 If the administrative agencies of local people's governments at all levels have the same or similar responsibilities, they shall, in principle, be undertaken by one administrative agency. If there are any disagreements between administrative agencies on the division of responsibilities, they should take the initiative to negotiate and resolve them. If consensus is reached through consultation, it shall be reported to the institutional establishment management authority of the people's government at the same level for record; if there is disagreement after consultation, the establishment management authority of the people's government at the same level shall be submitted to provide coordination opinions, and the establishment management authority shall report it to the people's government at the same level for decision. Article 11 The establishment of deliberation and coordination bodies by local people's governments at all levels shall be strictly controlled; if the functions can be delegated to existing agencies or the problems can be solved through coordination by existing agencies, no separate deliberation and coordination agencies shall be established. A discussion and coordination body established to handle a specific task within a certain period of time should clearly stipulate the conditions and time limit for its cancellation. Article 12 The deliberation and coordination agencies of local people's governments at or above the county level do not set up separate offices, and the specific work is undertaken by the relevant administrative agencies. Article 13 The administrative agencies of local people's governments at all levels shall establish necessary internal agencies based on work needs and the principle of leanness. The establishment, cancellation, merger, or change of specifications or names of internal agencies of the administrative agencies of local people's governments at or above the county level shall be submitted to the administrative agency of the people's government at the same level for approval.
『四』 How to define blockchain and what are the application scenarios of blockchain
Many people now think that blockchain is a universal technology that can do anything. Blockchain technology is somewhat regarded as A myth!
Regarding the definition of blockchain technology, American scholar Melanie Swann defined blockchain technology as an open, transparent and decentralized technology in her book "Blockchain: A New Economic Blueprint and Introduction" database.
Definition of Blockchain: Narrow VS Broad
As for the application scenarios of blockchain technology, it is natural to combine the differences between blockchain and other technologies. In terms of system characteristics.
Blockchain technology features include:
Blockchain is a global A database storage system that can be operated collaboratively in various places is different from traditional database operations where read and write permissions are in the hands of a company or a centralized authority (a characteristic of centralization). Blockchain believes that anyone with the ability to set up a server can participate. Nuggets from all over the world have deployed their own servers locally and connected to the blockchain network to become a node in this distributed database storage system; once joined, the node enjoys exactly the same rights as all other nodes and obligations (decentralized, distributed characteristics).
At the same time, those who provide services on the blockchain can perform read and write operations on any node in the system. In the end, all nodes around the world will complete the process again and again according to a certain mechanism. Synchronize in sequence to achieve complete consistency of data in all nodes in the blockchain network.
At the beginning of this year, the term blockchain began to enter everyone’s lives. From national leaders to aunts who dance square dances, everyone knows this term. This term is widely known by Bit Brought by coins.
As we all know, the first few dozen bitcoins could only be exchanged for one pizza. At its peak, it was more than 20,000 US dollars each, which has skyrocketed by more than a thousand times, which has also benefited a large number of wealthy people. Currently, there are blockchain The virtual currency generated by technology is gradually entering into everyone's life, and many people have joined the ranks of currency speculation. I often hear people say that if you buy the right currency a hundred times, a bicycle will become a sports car, and one coin will turn a young model. You can imagine how many of them are involved. Attractive.
Since 2008, various games applying blockchain technology have also become popular, such as development games (Network Letts Dog, 360 Block Cat), mining games (NetEase Planet, Virtual Earth, Gongxinbao), these are attracting everyone to join in the name of blockchain, and of course there are some that are really reliable, which requires everyone to identify them carefully.
Blockchain is a method that connects data blocks in an orderly manner and cryptographically ensures that they cannot be tampered with or forged.Distributed ledger (database) technology. In layman's terms, blockchain technology can achieve openness, transparency, non-tampering, non-forgery, and traceability of all data information in the system without the need for third-party endorsement. As an underlying protocol or technical solution, blockchain can effectively solve the problem of trust and realize the free transfer of value. It has broad prospects in the fields of digital currency, financial asset transaction settlement, digital government affairs, and certificate deposit and anti-counterfeiting data services.
Digital currency
After experiencing physical objects, precious metals, banknotes and other forms, digital currency has become the development direction of the digital economy era. Compared with physical currency, digital currency has the characteristics of easy portability and storage, low circulation cost, convenient use, easy anti-counterfeiting and management, breaking geographical restrictions, and better integration.
Bitcoin technically implements an electronic cash system in which both parties to the transaction can directly transfer funds to each other without the need for third-party transfer or arbitration. In June 2019, the Internet giant Facebook also released a white paper on its cryptocurrency Libra. Whether it is Bitcoin or Libra, the underlying technology they rely on is blockchain technology.
my country began the development of central bank digital currency as early as 2014. my country's digital currency DC/EP adopts a two-tier operating system: the central bank does not directly issue digital currency to the public. Instead, the central bank redeems the digital currency to various commercial banks or other legal operating institutions, and then these institutions exchange it for public supply. its use. In early August 2019, the central bank held a video conference on work for the second half of the year. The meeting called for accelerating the pace of research and development of the national legal digital currency.
Financial asset transaction settlement
Blockchain technology naturally has financial attributes, and it is causing disruptive changes in the financial industry. In terms of payment and settlement, under the blockchain distributed ledger system, multiple market participants jointly maintain and synchronize a "general ledger" in real time. Payment, clearing, and settlement that currently take two or three days can be completed in just a few minutes. tasks, reducing the complexity and cost of cross-bank and cross-border transactions. At the same time, the underlying encryption technology of the blockchain ensures that participants cannot tamper with the ledger, ensuring that transaction records are transparent and safe. Regulators can easily track transactions on the chain and quickly locate high-risk capital flows. In terms of securities issuance transactions, traditional stock issuance processes are long, costly and complex. Blockchain technology can weaken the role of underwriting institutions and help all parties establish a fast and accurate information exchange and sharing channel. Issuers handle issuance on their own through smart contracts, and regulatory authorities With unified review and verification, investors can also bypass intermediaries and conduct direct operations. In terms of digital bills and supply chain finance, blockchain technology can effectively solve the financing difficulties of small and medium-sized enterprises. It is difficult for current supply chain finance to benefit small and medium-sized enterprises in the upper reaches of the industrial chain, because they often do not have direct trade relations with core enterprises, and it is difficult for financial institutions to evaluate their credit qualifications. Based on blockchain technology, we can establish a consortium chain network covering core enterprises, upstream and downstream suppliersCore enterprises issue accounts receivable vouchers to their suppliers. After the notes are digitized on the chain, they can be transferred between suppliers. Each level of supplier can use the digital note certificate to achieve the corresponding amount of financing.
Digital Government Affairs
Blockchain can make data run and greatly streamline the service process. The distributed technology of blockchain can allow government departments to be centralized on one chain, and all service processes are delivered to smart contracts. As long as the service personnel pass the identity authentication and electronic signature in one department, the smart contracts can be automatically processed and transferred, and the subsequent steps can be completed in sequence. All approvals and signatures. Blockchain invoice is the earliest application of domestic blockchain technology. The tax department launched the "Tax Chain" platform for blockchain electronic invoices. The tax department, the issuer, and the payee join the "Tax Chain" network through unique digital identities, truly realizing "instant invoicing for transactions" and "immediate reimbursement of invoices" - in seconds Level invoicing and minute-level reimbursement accounting greatly reduce tax collection and management costs, and effectively solve problems such as data tampering, over-reporting of one ticket, and tax evasion. Poverty alleviation is another practical application of blockchain technology. Utilize the characteristics of openness, transparency, traceability, and non-tampering of blockchain technology to achieve transparent use, precise investment, and efficient management of poverty alleviation funds.
Evidence-based anti-counterfeiting
Blockchain can prove the existence of a file or digital content at a specific time through hash timestamps, and it is open, non-tamperable, and traceable. It provides perfect solutions for judicial forensics, identity certification, property rights protection, anti-counterfeiting and traceability, etc. In the field of intellectual property, the digital signature of blockchain technology and on-chain certificates can confirm the rights of text, pictures, audio and video, etc., and create and execute transactions through smart contracts, allowing creators to regain pricing power and preserve data formation in real time. The evidence chain covers the three major scenarios of rights confirmation, transaction and rights protection. In the field of anti-counterfeiting and traceability, blockchain technology can be widely used in various fields such as food and medicine, agricultural products, alcohol, and luxury goods through supply chain tracking.
Data services
Blockchain technology will greatly optimize existing big data applications and play a huge role in data circulation and sharing. In the future, the Internet, artificial intelligence, and the Internet of Things will generate massive amounts of data. The existing centralized data storage (computing model) will face huge challenges. Edge storage (computing) based on blockchain technology is expected to become a future solution. Furthermore, the non-tampering and traceability mechanism of blockchain ensures the authenticity and high quality of data, which becomes the basis for all data applications such as big data, deep learning, and artificial intelligence. Finally, blockchain can realize multi-party collaborative data calculations while protecting data privacy, and is expected to solve the problems of "data monopoly" and "data islands" and realize the value of data circulation. In response to the current blockchain development stage, in order to meet the blockchain development and application needs of general business users, many traditional cloud service providers have begun to deploy their own BaaS ("Blockchain as a Service") solutions. The combination of blockchain and cloud computing will effectively reduce the cost of enterpriseBlockchain deployment costs promote the implementation of blockchain application scenarios. In the future, blockchain technology will also play an important role in many fields such as charity, insurance, energy, logistics, and the Internet of Things.
The three words "blockchain" were completely ignited during the Spring Festival that just passed. The limelight overshadowed everything. Some people said that this was the arrival of a new era. The past It has become a classic, and some people say that it is all hype and is ultimately a bubble.
In fact, blockchain technology is not a new concept. It has been applied to many industries, such as electronic signatures, as early as the past two years. Recently, the third-party electronic signature platform eShanbao revealed the latest progress of blockchain applications to NewSeed.
Currently, blockchain technology is mainly used in e-signing products for certificate deposit and certificate issuance. The application scenarios include copyright protection and online signing. , web page forensics, phone recording, email storage, etc.
Take the rights protection of online works as an example. Since online rights protection generally adopts the method of collecting evidence after the fact, real-time confirmation of rights is not carried out in the process of evidence generation, so the entire confirmation process is difficult. The copyright process is time-consuming, difficult and costly to obtain evidence, and extremely difficult to prove and trace the source. It cannot meet the characteristics of rapid dissemination and large quantity of online works.
eShanbao's new intellectual property protection solution based on timestamp + blockchain starts from the user's real-name authentication and solidifies the information generated during the real-time solidification process. Electronic data, and through the time source service synchronized with the National Time Service Center, online works are stamped with legally valid timestamps to prove that electronic files have not been tampered with in a certain period of time. Blockchain technology can establish point-to-point trust in the network, ensuring that all blockchain nodes can record complete copyright confirmation and transaction records, and can trace their origins, truly realizing anti-repudiation and anti-tampering, and realizing a kind of distribution. trust infrastructure.
Founder and CEO Jin Hongzhou believes that the application of decentralized blockchain technology has greatly improved the efficiency of data storage and certification, and The credibility of the identity of the parties reduces the cost of trust, but it cannot replace the original centralized public key encryption technology. The two should complement each other. Through the combination of the two, it can provide users with real-time and reliable Confirmation plan.
Next, e-Shanbao will also focus on building a smart contract platform based on blockchain technology. Jin Hongzhou said that data storage, Issuing certificates is only a relatively superficial application based on blockchain technology. It is the first step to implement blockchain technology, and the realization of real smart contracts is the second step. “Smart contracts cannot simply be understood as electronic contracts; they refer toIt is a process, from the conclusion of the contract to the confirmation to the final execution. "Jin Hongzhou explained.
From a technical perspective, blockchain is not a brand-new technology, but an integration of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, smart contract and other computer technologies. New application model. Specifically, blockchain technology is a technical solution that collectively maintains a reliable database in a decentralized, high-trust manner.
Due to the characteristics of "decentralization" and "distribution" With advantages such as "automatic data storage", "traceability", "tamper resistance", and "openness and transparency", blockchain technology can effectively solve the problems of data authenticity, security and openness in the data field. A data management environment to prevent and avoid various data management problems such as data fraud, tampering, and loss, and promote efficient sharing and application of data. In the process of practical exploration, the application scope of blockchain technology continues to expand, especially in the field of public resource transactions. Empower public resource transaction management services.
Promote transaction data sharing and transaction witness
Promote transaction data sharing
Currently, the data of different trading centers are not interoperable, and the subject information of different trading centers needs to be entered repeatedly. During the bid evaluation process, it is difficult to verify the off-site performance provided by the bidders, and the same personnel are duplicated. Problems such as difficulty in troubleshooting as a project manager and low cost of breach of trust by transaction entities. Establishing a cross-regional entity database based on blockchain can well alleviate the above problems.
The distributed ledger features based on blockchain can Effectively guaranteeing the real-time or quasi-real-time sharing of data, it can reduce repeated entry operations of subject information; the use of blockchain information that cannot be tampered with can ensure the authenticity of the data flow process on the chain. The performance of bidders in the regional alliance is directly taken from the data on the chain. This makes it impossible to hide false performance. At the same time, the sharing of bidding behavior data through the blockchain provides a data basis for the development of "joint punishment of dishonest enterprises".

Blockchain-based transaction witness
The document "Guiding Opinions on Deepening the Integration and Sharing of Public Resource Trading Platforms" (State Office Letter [2019] No. 41) points out the need to optimize witness, venue, Information, archives, expert extraction and other services. However, at present, public resource transaction process witnessing is mainly based on manual on-site witnessing, which has limited witnessing strength, high occupation of human resources, and limited witnessing effect. Due to its centralized characteristics, the traditional digital witnessing system is easy to collect data afterwards Be tampered with, and the data is easily damaged or lost during the storage and migration process, which has certain flaws in terms of security and usability.
Utilize the distributed, difficult to tamper, and traceable characteristics of the blockchain to verify each transaction The data generated in the link are solidified and stored as evidence through time stamp technology, summary algorithm, and electronic signature.Technology Accurately record the time, content, and data sources of data generation. According to the technical characteristics of the blockchain, simple structured data can be directly saved on the blockchain. For unstructured layout files, videos, audio and other large files, the summary information and original files can be saved through the blockchain. Save via a distributed file storage service. When there are disputes or problems in a transaction, the blockchain can provide a set of credible transaction process data and clarify the responsibilities of all parties involved in the transaction. Achieve the goals of risk prevention and control in all aspects, traceability of the entire process, and improvement of all-round services.
Promote the rationalization of electronic guarantee rates
Promote financial services and corporate financing for bidding companies
Promote the rationalization of electronic guarantee rates
At present, electronic bidding deposit guarantee letters have certain applications in the field of bidding, solving the problem of bidding deposit funds for bidding companies. Occupancy issues. However, because financial institutions currently do not have reliable historical bidding behavior data of bidders, they are unable to judge the default risks of different bidders. As a result, the guarantee services charged to bidders adopt fixed rates, which makes a small number of bids with high default risks The cost of personal guarantee is allocated to most bidders with low default risk, which increases the guarantee rates for most bidders to a certain extent.
At present, it is up to the bidder to choose whether to use an electronic letter of guarantee, and the rate is the main choice basis for the bidder. If the bidder performance records are shared through the blockchain and the performance risks of different bidders are analyzed, it will be Different bidders provide different guarantee rates, which not only reduces the risks of financial institutions, but also reduces the use costs of most bidders and promotes the use of bid guarantees. To a certain extent, it can also encourage bidders to abide by their promises and maintain the order of the bidding market. .
Promote financial services for bidding companies
The bidding behavior of bidders is scattered in various trading centers, and the data is simply aggregated In a centralized information system, there is a risk of data tampering (untrustworthy), and valuable bidder transaction behavior data cannot be gathered and shared safely and reliably. Through blockchain technology, bidders from multiple trading centers are gathered, and historical bidding, winning bids, defaults, violations and other behavioral records provide data support for financial institutions to evaluate the bidders' credit in the bidding sub-sector.
Solve the financing problems of successful bidders
Traditional corporate loans mainly evaluate the company's solvency: collateral, audit There are requirements for accurate financial statements and sustained profitability, but most small and medium-sized enterprises cannot provide these "proofs" at all. Difficulty and expensive financing have become problems faced by many small and medium-sized enterprises in bidding activities. makeThe methods of the past will no longer work. To solve the financing difficulties of small and medium-sized enterprises, we can only rely on new technologies and new tools. With the help of the non-tamperable characteristics of blockchain, primary business data from multiple trading centers are gathered, and big data analysis technology is combined to build a portrait of a credible bidder. On the one hand, it improves the risk control level of financial institutions and taps high-quality bidding companies. On the other hand, it lowers the loan threshold for bidding companies and optimizes the service experience.
Drawing on the supply chain finance model, the bidder is a core enterprise with good credit in government departments, national enterprises and institutions, and the winning contract obtained by the winning bidder as a supplier is considered by financial institutions to be a high-quality asset. Apply for a loan from a financial institution. Under the traditional paper-based model, there is a risk of order and contract fraud and the process is cumbersome. Centralized information systems require operators to have strong authority. The distributed ledger and difficult-to-tamper characteristics of the blockchain will help solve the above problems. The contract signing between the tenderer and the bidder and the subsequent financial service links will be realized on the blockchain, which not only solves the problem of data credibility but also reduces the risk of corruption. The entire system relies on a centralized authority.
Through further analysis, we found that credit sales are currently prevalent among domestic enterprises, and the upstream suppliers of the winning bidder have a large funding gap. The credit of the bidder can only be passed to the winning bidder (the winning contract cannot be split or transferred), and the upstream suppliers Business owners are unable to obtain high-quality loans from financial institutions. If the winning contract is converted into a "pass" on the chain, the "pass" can be split, and the winning bidder holding the "pass" can pay part or all of the voucher to the upstream supplier, making it possible to discount and finance. The "tokens" on the chain can be split and transferred from first-level suppliers to second-level (and multi-level) suppliers, thereby allowing core enterprise credit to be transferred to multi-level suppliers. The shortage of funds from suppliers due to credit sales has been solved, improving the business environment; value transfer through the blockchain has greatly shortened the financing cycle; reducing supplier loan costs will help reduce the production costs of raw materials or intermediate products, and ultimately Increase bidders' profit margins and indirectly reduce bidders' costs.
Regarding blockchain, we can imagine a decentralized management model and technical processing method.
Let me give you an example. There are five people in your family, and they have never been able to figure out how to arrange work and handle family relationships.
So, you and your family discuss it together and simply use voting to solve the problem.
Then this way of voting to solve problems can be called the most elementary blockchain.
Decentralization solves problems.
What application scenarios can blockchain have?
In fact, many of our families and many organizations use blockchain management forms every day
However, this kind of blockchain application for organizational relationships cannot produce Economic Value.
What are the economic applications of blockchain?
The first type is used for tax deposit certificates, bank transfers, etc.
Make full use of the traceability function of the blockchain so that all records can be retrieved and queried at any time
The second type is applied to enterprise operation and management
Enterprises using blockchain management can better solve the problems of enterprise development and allow enterprises to Able to develop faster and make more money.
Summary: The application scenarios of blockchain include taxation, bank transfers, etc., and can also be applied to business operations.
The characteristics of blockchain are distributed accounting and decentralization, but the ultimate goal is to make people get along more equally. Technology is meaningful only when it serves human values, and technology that meets human value needs will develop. Therefore, blockchain is in line with human pursuit of freedom and equality, so its trend to become mainstream is unstoppable.
Currently, there are many blockchain gimmicks, which are basically used to issue coins. The newly launched ono is a decentralized, free and global social platform. Due to decentralization, your chat communication information is peer-to-peer and cannot be viewed by others. In other words, your every word and deed will no longer be recorded and reviewed at any time like it is now on WeChat, QQ, and Facebook, freeing you from the trouble of surveillance.
In fact, blockchain technology can be used in any field. Information that previously required third-party confirmation can be completed online and confirmed at multiple nodes, making it difficult (almost impossible) to delete.
At present, blockchain is still in its infancy, and the technology is not mature enough, but it is also a better time to enter.
Blockchain is a decentralized technology. Blockchain can be applied to all products currently covered by the Internet.
The most popular application industry at present is the financial industry.
An application that has been implemented is product traceability. Alibaba and JD.com are already using blockchain technology to fully trace the origin of some of the products they sell. Consumers can trace the origin of the purchased products. There are also many blockchain applications in the digital advertising industry. Since digital advertising traffic fraud causes losses of tens of billions of dollars every year, there are already blockchain application projects based on digital advertising, such as DCAD, which is based on blockchain. The digital advertising application of blockchain technology mainly solves the problem of traffic fraud
In the future, as the application of blockchain technology becomes more mature, it will be applied in many industries, creating a new ecosystem based on technological trust. Mode
What is blockchain If you explain blockchain in non-technical terms, blockchain is a place where data is stored. However, the data stored in the blockchain is safe and reliable and does not need to be managed by anyone. So in the Internet, a place where data and information are exploding, if there is such a place, it willIt's like a magical treasure land.
If you ask what the blockchain can do, it is better to say what applications require the use of the blockchain. As mentioned earlier, blockchain is a safe place, so wherever data needs to be protected securely on the Internet, blockchain technology needs to be used. For example:
Because the use of blockchain technology can better protect the data of policyholders, in today’s Internet, data is value and wealth, so value protection and value transmission are the future development directions of the Internet. And blockchain technology can really do just that.
If there are any deficiencies, you are welcome to comment and correct me.
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.
The two parties involved in the transaction do not need to know who the other party is, nor do they need a third party for trust endorsement. They only need to trust a common algorithm to establish mutual trust and conduct direct transactions.
Its characteristics are trustlessness and decentralization. The destruction of each node's ledger has no impact on the entire blockchain. The blockchain runs point-to-point payments without a center that may cheat, and the security is greatly improved. Improved, the entire transaction network has changed from a star structure to a point-to-point P2P structure.
In the future, blockchain will be used in many fields and will have a great impact on human life. . It can be widely used in fields ranging from digital currency to securities and financial contracts, medical care, games, artificial intelligence, smart contracts, Internet of Things, e-commerce, file storage and other fields.
1. Cloud storage
This is the statistics of current cloud storage on the Internet. In terms of volume, Google has the largest volume, which is 8,000PB. So what if we share the idle data on the Internet?
Starlight Cloud builds a blockchain data computing and storage lake through Starlight Chain, with a total storage capacity of 15,000P (approximately 15,728.64 billion G) in the future. This will be more than 10 times that of Alibaba Cloud's 1500PB! It is also more than four times the size of the Taizhou Storage Center, the largest storage lake in the world after expansion.
2. Medical aspects
Using blockchain technology to save personal medical records also retains personal medical historical data, which can be used when seeing a doctor or planning for your own health in the future. Historical data can be called directly. These data are highly private, and the use of blockchain technology also helps protect patient privacy.
『五』What are the policies to promote the development of blockchain?
Legal analysis: On October 25, national leaders presided overThe collective study meeting of the Political Bureau of the CPC Central Committee listed blockchain as an important breakthrough for independent innovation technology.
In the 19 days since then, local governments have issued a total of 44 related policies to encourage the development of blockchain, involving 20 provinces.
Government affairs, medical care, finance and smart cities have become the areas where local governments value blockchain implementation most.
In the process of actively promoting the implementation of blockchain, local governments are also trying to combine their own advantages and local characteristics. For example, in Shanxi, energy has become a key area for blockchain implementation.
Legal basis: "The Fourteenth Five-Year Plan for National Economic and Social Development of the People's Republic of China and the Outline of Long-term Goals for 2035" Article 3 Strategic Orientation: Promote high-quality development during the "14th Five-Year Plan" period , we must base ourselves on the new development stage, implement new development concepts, and build a new development pattern. Grasping the new development stage is the realistic basis for implementing the new development concept and building a new development pattern. Implementing the new development concept provides an action guide for grasping the new development stage and building a new development pattern. Building a new development pattern is to respond to the opportunities and challenges of the new development stage. , strategic choices to implement new development concepts. We must persist in deepening supply-side structural reforms, lead and create new demands with innovation-driven, high-quality supply, and improve the resilience of the supply system and its adaptability to domestic demand. We must establish an effective system to expand domestic demand, accelerate the cultivation of a complete domestic demand system, strengthen demand-side management, and build a strong domestic market. We must unswervingly advance reform, break down institutional obstacles that restrict economic circulation, and promote the circulation of production factors and the organic connection between production, distribution, circulation, and consumption. We must unswervingly expand opening up, continue to deepen openness based on the flow of factors, steadily expand openness based on institutions, and rely on the domestic economic cycle system to form a strong gravitational field for global factor resources. It is necessary to strengthen the leading role of the domestic general cycle, improve the efficiency and level of the domestic general cycle with the international cycle, and realize the mutual promotion and advancement of the domestic and international dual cycles.
『Lu』 What are the applications of blockchain in the industry

Public service field
Blockchain is used in public management, energy, transportation and other fields. It is closely related to people's production and life, but the centralized nature of these fields also brings some problems, which can be transformed with blockchain. The decentralized, fully distributed DNS service provided by the blockchain can realize domain name query and resolution through point-to-point data transmission services between various nodes in the network, and can be used to ensure that the operating system and firmware of an important infrastructure are not been tampered with, canTo monitor the status and integrity of software, detect unwanted tampering, and ensure that data transmitted by systems using IoT technology has not been tampered with.
Digital copyright field
Through blockchain technology, works can be authenticated, proving the existence of text, video, audio and other works, and ensuring the authenticity and uniqueness of ownership. After the rights of the work are confirmed on the blockchain, subsequent transactions will be recorded in real time, realizing full life cycle management of digital copyright, and can also be used as a technical guarantee in judicial evidence collection. For example, Mine Labs, a startup company in New York, USA, has developed a blockchain-based metadata protocol. This system called Mediachain uses the IPFS file system to realize copyright protection of digital works, mainly for copyright protection applications of digital pictures
