① Someone recommended an app called Zhongnong Chain. Does anyone know what this app is for?
The person who engages in pyramid schemes to attract people, and the math coin wallet has been involved in financing. , and the domestic blockchain state regulations stipulate that service entities are not allowed to raise funds, otherwise it will be illegal fundraising, and the currency has also become a pyramid scheme currency. This is different from foreign countries, where foreign blockchains adopt a financing model. But when you are in China, you are thought to be opportunistic in foreign countries. Think about it, even if you bring in foreign investment in direct selling, the procedures must be complete and the brand must be complete, but the model must be in accordance with the relevant laws of the country. This is why direct selling is different abroad and at home. Many direct selling companies have even withdrawn from the Chinese market. Do you understand this comparison?
② What are the policies to accelerate the research and development and industrialization of blockchain technology?
In order to speed up the research and development and industrialization of blockchain technology, the government can adopt a series of policy measures. First, investment in the blockchain industry must be increased to provide enterprises and researchers with sufficient funds to develop new applications. Secondly, corresponding laws and regulations must be implemented to promote industry standardization, regulatory compliance, risk management, and market competition. In addition, it is necessary to publicize, educate and promote Sprocket blockchain technology; and carry out some national strategic talent training such as "learning talents". In short, through the above methods to promote_
③ The CTFU platform application is put into production and see how the blockchain promotes the development of the banking industry
On August 28, the China Banking Association organized the "China Symposium on the construction of "Trade Finance Inter-bank Transaction Blockchain Platform" (referred to as "CTFU Platform"). At the meeting, the China Banking Association, the Industrial and Commercial Bank of China, the Agricultural Bank of China, the Bank of China, the China Construction Bank, and the Bank of Communications jointly signed the "CTFU Platform Service Agreement", officially kicking off the launch of the CTFU platform application.
As a new technology in the financial field, blockchain has continuously expanded its application scenarios and has had a profound impact on the entire banking industry. Various banks have also increased their emphasis on blockchain technology and utilized regional Blockchain technology solves current industry pain points.
What are the pain points in the banking industry?
[if !supportLists]1, [endif] Audit and verification costs are high. Currently, many bank operations require offline operations, and banking business relies on paper documents. A large amount of paper materials are required during the review and verification process, which consumes a lot of manpower and material resources.
[if !supportLists]2, [endif] Risk monitoring is difficult. Bank trade involves a wide range of transactions, with long transaction chains and multiple settlement methods. Sometimes regulatory data is not updated in a timely manner, which will bring potential business risks to banks.
[if !supportLists]3, [endif] Information sharing is difficult. Each department in the transaction chain is relatively independent, and each departmentThey have their own systems, standards and management models, and information transparency is low, making it difficult to share information between departments.
[if !supportLists]4, [endif] Financing costs are high. In order to reduce their own risks, banks require financing deposits and provide mortgages, pledges, guarantees, etc., which further increases the financing costs of enterprises.
How does blockchain solve these pain points?
Taking CTFU as an example, when Tian Guoli, president of the China Banking Association and chairman of China Construction Bank, introduced the CTUF platform, he pointed out that the platform will play four roles:
1. Realize the standardization, electronicization and intelligence of inter-bank trade financial product transaction information and promote the development of supply chain finance.
Use blockchain technology to put transaction information on the chain, unify standards among banks, and then digitize various paper materials to reduce labor and material costs while ensuring transactions The credibility of information promotes the development of supply chain finance.
2. Improve trade financing efficiency, reduce financing costs, and enhance the quality and efficiency of financial services to the real economy.
In the blockchain, information will become more transparent, and communication between various departments within the bank will become more convenient and faster, improving the collaboration efficiency of all parties in the financing process. Processes are optimized and financing costs are reduced.
3. Use the characteristics of blockchain technology such as "distributed storage, transaction traceability, and non-tampering" to effectively prevent and control trade finance business risks.
Utilizing the non-tamperable characteristics of the blockchain, combined with digital signatures and transaction traceability, we can effectively achieve information credibility, effectively solve the bank's trust cost and audit verification cost, and facilitate the bank's trade finance industry Carry out risk management and control.
4. It is conducive to resource sharing and utilization and improves the association's service level to members.
With the help of blockchain technology, banks can share and utilize resources and information through end-to-end data exchange and effective verification.
Currently, trade finance and supply chain finance are the most feasible application scenarios of blockchain in traditional finance. But the possibilities brought by blockchain technology are certainly not limited to this. Banks will increasingly explore blockchain technology. The exploration and application of blockchain technology in the field of trade finance is worth looking forward to.

④ What is the concept of blockchain? Is blockchain a scam? The most complete explanation of blockchain
What is the concept of blockchain?
On October 25, 2019, the country promoted developmentBlockchain. Overnight, the blockchain concept became popular.
However, many people are hearing about blockchain for the first time.
So, what is blockchain?
Let’s take a look at it from an academic perspective:
Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. Blockchain is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each data block contains a batch of Bitcoin network transactions. Information, used to verify the validity of its information (anti-counterfeiting) and generate the next block.
In fact, blockchain is essentially a decentralized database.
Is blockchain the same as Bitcoin? Blockchain is not Bitcoin. The first application of blockchain is Bitcoin.
What are the characteristics of blockchain? Now let’s take a look at several characteristics of the blockchain:
1. Decentralization:
The most important feature of the blockchain is decentralization, and the blockchain system is different Based on a centralized database, it is not controlled by any person or entity. Through distributed storage, data is completely copied and distributed on multiple computers, and each node realizes information self-verification, transmission and management.
2. Non-tamperability:
The blockchain system also has the characteristics of non-tamperability. In the blockchain system, each node is the center and no information can be changed, not even the administrator can modify this information. The consensus mechanism of the blockchain has the characteristics of "the minority obeys the majority" and "everyone is equal". Only when more than 51% of the accounting nodes in the entire network are controlled, it is possible to forge a non-existent record. This situation is basically impossible, thus eliminating the possibility of fraud.
3. Publicity:
In a blockchain system, all nodes in the network can easily access information. The foundation of blockchain technology is open source. In addition to private information being encrypted, blockchain data is open to everyone. Anyone can query blockchain data and develop related applications through public interfaces, so the entire system information is highly transparent. .
4. Independence:
Because the blockchain is decentralized, it can facilitate peer-to-peer transactions, so there is no need for a third party whether in transaction or exchange of funds. of approval.
Based on consensus specifications and protocols, the entire blockchain system does not rely on other third parties. All nodes can automatically and securely verify and exchange data within the system without any human intervention.
First assume oneEnvironment: 6 people live in dormitory 188 of the university
There is a ledger in the dormitory for Xiao Li, who is good at calculation, to keep accounts.
In the beginning, when the dormitory sold paper boxes or bought some public items, Xiao Li would record them in the ledger. If Xiao Li wanted to enrich himself and made false accounts, there would be less money in the account books, but no one would know.
After all, there is already a general ledger room, who would have nothing to do to keep track of the ledgers?
However, one day, because Xiao Li took more, there were obvious errors in the account book. Now, he could no longer hide it, so Xiao Li had to admit his mistake and make up the money.
So, how to solve this problem?
If blockchain is used to solve the problem:
Everyone in the dormitory takes out a ledger, and every time a transaction occurs, everyone records it in their own ledger. , such problems will not arise, because everyone is keeping accounts and can see the transaction records and final results on the ledger.
Xiao Li can’t change, you can’t change, and neither can your lower bunk. No one can change it.
This is because the previous accounting model was a centralized accounting model, and the current accounting model is a decentralized accounting model, where everyone is the center and everyone is the accountant.
If someone wants to change it, it will obviously be ineffective if they only change the data on their own account book, unless they bribe three people.
So, is blockchain a scam?
With the emergence of the great benefits of blockchain, in a short period of time, the prices of blockchain-related assets have soared, and ordinary investors are becoming more and more interested in blockchain. And criminals have also taken aim at this. There are some criminals who wear the gorgeous cloak of "blockchain" and use the blockchain to commit fraud or issue digital currencies without permission, leading many people to think that the blockchain is a scam.
But in fact, it is not. Blockchain is just a technology. If it can be used well, it will benefit the public and promote the development of the industry.
In particular, the application of blockchain is very wide and can be applied to almost everything of value to human beings.
Medical field: For example, when you go to the hospital for medical treatment, you can directly check the previous medical treatment in your own database, which greatly saves medical resources and saves medical expenses for repeated examinations.
Food traceability: Do you know where the food on your table comes from? Which logistics team is transporting it? This information can be tracked using blockchain. It can provide us with a single source of truth.
Supply chain application: For example, when we buy a product on a certain website, this product comes from the factoryIt leaves the factory, goes to the distributor for logistics turnover, goes to the seller's store warehouse, and then reaches the hands of consumers. During these processes, if something goes wrong, only you will know about it, and others, especially consumers, will not.
Well, this is where I introduce you to the relevant knowledge about the concept of blockchain. I hope it can be helpful to you.
⑤ How to define blockchain and what are the application scenarios of blockchain?
Nowadays, many people think that blockchain is a universal technology that can do anything, which is somewhat different. Blockchain technology is 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, people 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 (online Letts Dog, 360 Block Cat), mining games (online games)Easy Planet, Virtual Earth, Gongxinbao), these are attracting everyone to join in the name of blockchain. Of course, there are also some that are really reliable, which requires everyone to identify them carefully.
Blockchain is a distributed ledger (database) that connects data blocks in an orderly manner and cryptographically ensures that it cannot be tampered with or forged. 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 has long procedures, high costs, and complex links. Blockchain technology can weaken the role of underwriting institutions and help all parties establish fast and accurate information exchange and sharing channels. Issuers handle issuance on their own through smart contracts, and regulatory authorities Unified review and verification, investors can also bypass intermediaries for 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 suppliers, financial institutions, etc. The core enterprises issue accounts receivable vouchers to their suppliers. After the bills are digitized and uploaded to the chain, they can be uploaded to the supplier Transfer between them, each level of supplier can realize the corresponding amount of financing with the digital bill certificate.
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 "instant reimbursement after invoicing" - in seconds Level invoicing and minute-level reimbursement accounting significantly 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 implement data privacy protectionMulti-party collaborative data computing 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 enterprise blockchain deployment costs and 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 of evidence, 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 in the process in real time. 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, eSignBao will also focus on building a smart contract platform based on blockchain technology. Jin Hongzhou said that data storage and certification are only superficial aspects based on blockchain technology. Application is the first step to implement blockchain technology, and realizing real smart contracts is the second step. "Smart contracts cannot simply be understood as electronic contracts. They refer to 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 a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, encryption algorithms, and smart contracts. Specifically, blockchain technology is a technical solution that collectively maintains a reliable database in a decentralized, high-trust manner.
Due to its advantages such as "decentralization", "distributed data storage", "traceability", "anti-tampering", and "openness and transparency", blockchain technology can effectively solve data problems. By establishing a trustworthy data management environment, we can prevent and avoid various data management problems such as data fraud, tampering, and loss, and promote the efficient sharing and application of data. In the process of practice and exploration, the application scope of blockchain technology continues to expand, especially in the field of public resource transactions, and continues to empower public resource transaction management services.
Facilitate transaction data sharing and transaction witnessing
Facilitate transaction data Share
Currently, the data of different trading centers are not interoperable, and the subject information of different trading centers needs to be entered repeatedly. It is difficult to verify the off-site performance provided by the bidders during the bid evaluation process. It is difficult to troubleshoot the same person repeatedly serving as project manager. Issues such as low cost of breach of trust. Establishing a cross-regional subject database based on blockchain can well alleviate the above problems.
The distributed ledger feature based on the blockchain can effectively ensure the real-time or quasi-real-time sharing of data, and can reduce the repeated entry of subject information; the use of blockchain information that cannot be tampered with can ensure the data circulation process on the chain. The authenticity of the bidders in the regional alliance is directly obtained from the on-chain data, making it impossible to hide the fake 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
"Guiding Opinions on Deepening the Integration and Sharing of Public Resource Trading Platforms" ( The State Office Letter [2019] No. 41) pointed out the need to optimize services such as witnessing, venues, information, files, and expert extraction. However, at present, public resource transaction process witnessing is mainly based on manual on-site witnessing, which has limited witnessing intensity, high occupation of human resources, and limited witnessing effect. traditionalDue to its centralized characteristics, the digital witness system is prone to data tampering afterwards, and the data is easily damaged or lost during storage and migration, which has certain flaws in terms of security and usability.
Utilize the distributed, difficult to tamper, and traceable characteristics of the blockchain to solidify and store the data generated in each transaction link, and accurately record the data generated through time stamp technology, summary algorithm, and electronic signature technology. Time, content, data source. 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.
Solving the financing problems of bid-winning companies
Traditional corporate loans mainly evaluate the company’s solvency: there are requirements for collateral, audited statements, sustained profitability, etc., but most Most small and medium-sized enterprises simply cannot produce these "certificates", and difficult and expensive financing has become a problem faced by many small and medium-sized enterprises in bidding activities. Using the 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 trustworthiness 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 discountable and financing. 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; through value transfer through the blockchain, the financing cycle has been greatly shortened; the cost of supplier loans has been reduced, which 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 traffic fraud in digital advertising 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.Use it to create a new ecological model based on technological trust
What is blockchain If you explain blockchain in non-professional terms, blockchain is a place to store data, but in the blockchain The stored data is safe and reliable, and no one needs to take care of it. Therefore, in the Internet, a place where data and information are exploding, having such a place will be 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 chained data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-tamperable. 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 15.72864 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 history.Historical data can be directly called when seeing a doctor in the future or making plans for your own health. These data are highly private, and the use of blockchain technology also helps protect patient privacy.
⑥ Direct to Digital Expo丨Blockchain Standardization and Application Innovation Summit released three innovative results
Zhang Ping, Chief Engineer of the Cyberspace Administration of Hebei Provincial Committee Introduction, blockchain is one of the hot spots of this expo. The "Hebei Province Blockchain Special Action Plan (2020-2022)" released by Hebei Province last year clarified the development goals of Hebei Province's blockchain technology and industrial application. ——By the end of 2022, there will be 20 leading enterprises and leading enterprises in blockchain-related fields in Hebei Province, cultivate a number of blockchain application products, and strive to create 1-3 nationally renowned blockchain brands and form 3 regional influence It has a strong blockchain industry cluster park and its blockchain industry competitiveness ranks among the top in the country. To this end, Hebei Province is committed to introducing well-known domestic and foreign enterprises, gathering the most advanced technology, the most cutting-edge innovative concepts, and the most high-end human resources to cultivate innovative forces for the development of Hebei's blockchain industry.
"Hebei Provincial Characteristic Agricultural Products Blockchain Traceability Platform" was jointly developed by the Institute of Applied Mathematics, Hebei Academy of Sciences and Huaye Hebei Co., Ltd. Wang Zhiqiang, deputy director of the Institute of Applied Mathematics of the Hebei Academy of Sciences, introduced that the platform fully integrates blockchain with big data, Internet of Things, artificial intelligence and other technologies to realize the full chain traceability of production, logistics and sales information of specialty agricultural products, making production Operators, the public and regulatory authorities can participate together to build brands, enhance product value, and promote high-quality development of the agricultural economy.
It is reported that the “Hebei Province Specialty Agricultural Products Blockchain Traceability Platform” has three most prominent features:
First, one vote, one code, and object code locking. Intelligent identification and matching of business entity information and sales documents effectively solves problems such as multiple data sources, poor quality, and inconsistency between upstream and downstream.
Then there is the whole-chain evidence storage and accurate traceability. With the traceability code as the carrier and responsibility and flow management as the core requirements, agricultural product circulation data, electronic vouchers and other information are uploaded to the chain to achieve functions such as data non-tamperability and transaction traceability, and improve data throughput through the standardization of data storage and exchange. Key performance indicators such as volume and system response speed.
The third one is multi-source fusion and targeted regulation. On the basis of the blockchain system, for the characteristic agricultural product industry chain, a fusion model of production, circulation and inspection big data has been established to achieve targeted supervision and intelligent decision-making based on big data analysis, and comprehensively enhance the brand of on-chain products. Credibility.

"Wang Zhiqiang introduced that the Hebei Academy of Sciences is also exploring another quality route, cooperating with the Julu County Government to promote the "One Flower Supports Hundreds of Industries" project, using "blockchain empowered agriculture" as the entry point to create an agricultural digital estate, and then Promote the integrated development of primary, secondary and tertiary industries in the county, and ultimately achieve "one flower blooms, all industries prosper".
This blockchain standardization and application innovation summit is hosted by the China International Digital Economy Expo Organizing Committee, China Hosted by the Electronic Technology Standardization Institute, Software Institute of the Chinese Academy of Sciences, and Hebei Academy of Sciences.
⑦ What is blockchain
What is blockchain
District What is the blockchain? Many people are not very clear about what the blockchain is. Some people have even never heard of it. In fact, the blockchain is a common one. I have sorted it out for everyone. Related information about what blockchain is.
What is blockchain 1Speaking of blockchain, we have to mention its twin brother-Bitcoin.
Going back in time Exactly 11 years ago. On November 1, 2008, the world was shrouded in the huge shadow of the financial crisis. On that day, a mysterious geek who called himself "Satoshi Nakamoto" sent a group email.
Attached to the email is a paper titled: "Bitcoin: A Peer-to-Peer Electronic Cash System."
Satoshi Nakamoto said in the email that he is working on a new electronic cash system that The system is completely peer-to-peer and does not require any trusted third party. About half a month later, Satoshi Nakamoto published the source code of the Bitcoin system non-stop.
On January 3, 2009, a Interesting inventions turned out. Satoshi Nakamoto generated the first Bitcoin block on the server, which is the so-called "Bitcoin genesis block". From then on, the Bitcoin system was officially launched.
Having said that, you might as well stop and think about how we conduct cash transactions in real life.
Suppose you borrow 10,000 yuan from a friend and promise to pay back the money after one month. You may choose to use bank card transfer to repay. The bank is responsible for deducting 10,000 yuan from your deposit account and adding 10,000 yuan to your friend's deposit account.
Here, the bank is responsible for An accounting institution. The underlying reason why you choose bank transfer is that you believe it is more reliable and will help you transfer 10,000 yuan to a friend.
However, in the digital world, invent a Currency is another matter.
The unsung hero of the Bitcoin game
First of all, Satoshi Nakamoto hopes to have direct peer-to-peer transactions, bypassing banks as a third party. This problem is easy to solve , then there would be no banks. Users would issue their own currencies through a unique mechanism and trade directly with each other.
But this brings another problem. There is no bank as a reliable intermediary responsible for bookkeeping. ,useSince the customers don’t know each other, how can they ensure that no one cheats on them during the transaction?
For example, in the digital world, electronic files can be easily copied. 10 yuan of digital currency turns into 100 yuan by copying and pasting it with the mouse 10 times. Isn’t it a mess?
To solve this problem, we need to provide a mechanism for everyone to trust each other.
The method adopted by the Bitcoin system is to record all transaction processes openly and transparently in chronological order. These records are permanent and cannot be tampered with. This way you won't be able to do anything sneaky.
With these mechanisms, the Bitcoin system operates successfully.
This system stores data in units of data blocks, which are blocks. Approximately every 10 minutes, new blocks will be added. Each block records the detailed transaction process of Bitcoin and is timestamped. Different blocks are connected in chronological order through a certain algorithm, which is a chain.
Together, they are called "Blockchain".
In this way, the blockchain took root with the birth of Bitcoin. If Bitcoin is the star in front of the spotlight, blockchain is the hero behind the scenes responsible for providing a trust mechanism in the underlying technology.
Brand new changes in accounting methods
Although behind the scenes, the talent of blockchain was quickly discovered.
In technical terms, blockchain is a distributed ledger technology. To understand it, let’s take the simplest example.
Suppose your family keeps accounts like this: you, your father, and your mother each have an account book. You each record your own expenses, and at the end of each month, you tally the total household expenses together.
But dad likes to buy cigarettes, mom likes to stock up on cosmetics, and you like to buy snacks. You may both miss a few entries intentionally or unintentionally, and sometimes make corrections in the ledger. Therefore, when checking the accounts at the end of the month, there is always a discrepancy with the actual expenditure of the family.
In order to change this situation, you bought a new account book. You, your father, and your mother jointly use a new account book to keep accounts, remind and supervise each other, and check every expense together.
At the same time, you also agreed that once the expenses are clearly recorded, no alteration or deletion is allowed. After trying it for a few months, you found that this joint ledger matched the actual expenses of the family much more closely.
Blockchain is the second accounting method. The little story above tells us that it has at least these major features or benefits.
First of all, it is decentralized. The database that was previously maintained by one party has become jointly maintained by multiple parties. Everyone writes data together based on consensus, and no one can control the data alone.
Secondly, it allows everyone to switch from keeping separate accounts to joint accounting, which brings consistency and openness to the data.bright.
In addition, the blockchain only allows data to be written, not deletion or modification, which prevents data from being secretly tampered with.
Mutual trust between strangers
In reality, many scenarios are much more complicated than how to keep accounts at home. Moreover, many aspects of financial transactions and business processing are mostly operated by strangers. How can we make everyone trust each other?
It’s blockchain’s turn to show its talents. Don’t forget, it can provide a mechanism for everyone to trust each other from the underlying technology.
For example, when you usually go to the wet market to buy things, you may worry about whether fish, shrimp, and vegetables are safe. Some companies see business opportunities and move the data of farmers and fish ponds to the blockchain. In this way, you will know which fish pond the fish you buy comes from, and you will feel more confident when eating.
For another example, links to fundraising for seriously ill patients often appear in Moments. When making a donation, you may have some concerns: Is the patient's condition real? Can donations really be delivered to patients?
In order to eliminate these concerns, some Internet charity organizations use blockchain to allow you to clearly view the steps for using your donation. If the review finds that the patient's condition is not true, the blockchain system will automatically return the donation to your account.
In the future, what changes can blockchain bring to our lives?
It is conceivable that when blockchain is widely used in various fields of society, it will become an important infrastructure in the information age and can solve many of the headaches that currently cause us.
For example, blockchain will allow countless islands of information to be "chained" together. When seeing a doctor, there is no need to repeat the examination just because you change hospitals. Entrepreneurs do not have to go to multiple departments to go through a procedure; many transactions no longer need to be done. Third-party guarantees are required, consumers no longer worry about non-refundable deposits, and creators do not have to worry about their works being stolen but getting nothing...
What is blockchain 2From an academic perspective, blockchain is New application models of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms. Blockchain is essentially a decentralized database.
Many people still don’t understand this explanation, so let me make a simple metaphor.
Hypothetical situation: Suppose you have a ledger at home and you are asked to keep accounts. In the past, your parents gave you your salary and asked you to record it in your account book. If you are greedy and want to buy something delicious in the meantime, the record in the ledger may be less than ten yuan.
This is just an example. I believe that when we were children, everyone probably wanted to take some money from their parents’ pockets to spend.
Ways to use blockchain to solve problems:
If you use the whole family mobilization method to keep accounts, the above-mentioned problems will not exist, because you are keeping accounts, and your father They are also keeping accounts, and your mother is also keeping accounts. They can all see the general ledger, and you can’t change it, and neither can your parents.There is nothing you can do about the dad who wants to buy cigarettes and the glutton who wants to eat.
Functional "blockchain"
It can not only record every transaction, but also can be programmed to record almost everything of value to mankind. Things: birth and death certificates, marriage licenses, title deeds, degrees, financial accounts, medical history, insurance claims, ballots, food sources, and anything else that can be represented by a code.
Each block is like a hard disk, which saves all the above information and then encrypts it through cryptography technology. The saved information cannot be tampered with.
Every 10 minutes, the blockchain system will check all data generated during the period (such as transaction records and records of when the block was edited or created, etc.) and store these data in a new area. On the block, this block will be connected with the previous block to form a chain. Each block must contain relevant information from the previous block to be effective.
Characteristics of blockchain
1. Exceptionally safe:
Unlike centralized databases owned by companies or government agencies, blockchain is not controlled by anyone. or entity's control, data is replicated (distributed) in its entirety across multiple computers.
Unlike centralized databases, there is no single entry point for attackers, and data security is more guaranteed.
2. Non-tamperability:
Once entered into the blockchain, no information can be changed, and even the administrator cannot modify this information.
Once something appears, it cannot be changed. This attribute is of great significance to the changeable and ever-changing online world that humans currently live in.
3. Accessible:
All nodes in the network can easily access information.
4. No third party:
Because the blockchain is decentralized, it can facilitate peer-to-peer transactions, so whether you are trading or exchanging funds, there is no need for a third party of approval.
Blockchain itself is a platform.
Blockchain technology refers to a way for all people to participate in accounting. There is a database behind all systems. You can think of the database as a big ledger. Currently, each is keeping its own account.
Since there is no centralized intermediary agency, letting everything run automatically through preset programs can not only greatly reduce costs, but also improve efficiency. And since everyone has the same ledger, it can ensure that the ledger recording process is open and transparent.
Blockchain technology is the underlying technology of Bitcoin. Without the operation and management of any centralized organization, Bitcoin has been running very stably for many years without any problems, so some people have noticed its The underlying technology abstracts out the Bitcoin technology, called blockchain technology, or distributed ledger technology.
According to a report released by Santander, Spain's largest bank, if all banks around the world use blockchain technology internally around 2020, they will save approximately US$20 billion in costs per year. Such data is enough to illustrate the tremendous changes and breakthroughs that "blockchain" has brought to the traditional financial field.
Cloud computing is usually defined as providing dynamic, easily scalable and often virtualized resources through the Internet, but it is often a centralized organization that provides a cloud computing platform. The network composed of blockchain generally does not have a specific organization, so blockchain is closer to the definition of a distributed computing system and is a type of distributed computing.
The future development and application scenarios of blockchain
1. Digital identity
Many people will encounter "prove that my mother is me" when applying for various certificates. "Mom" dilemma, with blockchain, you no longer have to worry about it.
It turns out that our birth certificates, real estate certificates, marriage certificates, etc. need a central node for everyone to recognize them. Once cross-border, contracts and certificates may become invalid because of the lack of a global central node.
The non-tamperable nature of blockchain technology has fundamentally changed this situation. Our birth certificates, real estate certificates, and marriage certificates can all be notarized on the blockchain and become things trusted by the world. , of course, it can also easily prove "my mother is my mother".
2. Health care
Simply put, it is to use the blockchain to establish a universal record repository with timestamps, so that different databases can extract data information.
For example, when you go to see a doctor, you don’t have to change hospitals for repeated examinations, and you don’t have to worry about reimbursement for medical insurance, which can save time and expenses.
3. Travel consumption
For example, we often use apps such as Ctrip and Meituan to find and place orders for hotels and other services, and each platform gets commissions from them.
The application of blockchain is to remove middlemen and create a secure, decentralized way for service providers and customers to connect and trade directly.
4. More convenient transactions
Blockchain can make payments and transactions more efficient and convenient. The blockchain platform allows users to create smart contracts that become active when certain conditions are met, meaning that automatic payments can be released when both parties to a transaction agree that their conditions are met.
5. Strictly control product quality
If you buy an apple, with blockchain technology, you can know the entire process from the production of the fruit farmer to the circulation link. Among them are government regulatory information, professional testing data, enterprise quality inspection data, etc. A smart supply chain will make the food we eat and the products we use every day safer and give us more peace of mind.
6. The art of property rights protection
The creator puts his work on the blockchain, and if someone uses his work, he will know immediately. Corresponding royalties are also automatically paid to the creator.
Blockchain technology not only protects copyright, but also helps creators sell their works to consumers better and more directly, without the need for the assistance of distribution companies.
What is blockchain 3Advantages of blockchain
Decentralized, it does not require the intervention of a third party and enables point-to-point transactions, coordination and collaboration. Because the data is distributed in various nodes through algorithms and has a unique verification mechanism, no one organization or individual can control the global data. Since it is distributed in various nodes, any node stopping work will not affect the entire system. Operation, this decentralized network will greatly improve data security. The data in the system is jointly maintained by various nodes with maintenance functions.
Openness. In addition to the private information of all parties being encrypted, the blockchain data is open to everyone. Anyone can query the blockchain through the public interface. Data and development related applications, so the entire system information is highly transparent.
Where does blockchain come in?
Blockchain is an open, transparent, decentralized and secure technology. This technological revolution is applied to the Internet. For data-sensitive fields such as medical care, public opinion supervision, and ecological testing, it can prevent data from being tampered with and ensure the authenticity of the data.
In short, blockchain is not just a form of virtual currency, its advantages will play an important role in many industries.
⑧ Four during the "14th Five-Year Plan" period Efforts have been made in all aspects to build Chongqing into a blockchain industry highland
Recently, reporters learned from the first meeting of the city’s blockchain development management overall coordination mechanism that during the “14th Five-Year Plan” period, our city will start from the planning In terms of layout, industrial ecology, technological breakthroughs, application integration, etc., we will accelerate the cultivation and innovative application of the blockchain industry.
In recent years, our city’s blockchain industry cultivation and innovative applications have achieved remarkable results. First of all, the development of industrial agglomeration is accelerating. More than 60 well-known companies such as Qulian, Deakin, Jinwowo, and Inspur Cloud Chain have signed contracts to settle in the Chongqing Blockchain Industrial Park, and the industrial agglomeration area has initially taken shape. There are also many highlights in the blockchain application demonstration. The country's first blockchain government service platform was launched in Chongqing, and the first electronic business license based on blockchain technology was issued. The "Spark Network" super node settled in Chongqing, and Yibaoquan's "blockchain + judicial + electronic data storage "Certificate" system won the title of Industrial Internet Pilot Demonstration Project of the Ministry of Industry and Information Technology.
The person in charge of the Cyberspace Affairs Office of the Municipal Party Committee introduced that during the “14th Five-Year Plan”, our city will make efforts in four aspects to vigorously promote the development and management of the blockchain industry to a new level and build an “intelligent manufacturing town” for our city. ""Smart City" injects new momentum.
In terms of industrial ecosystem, our cityIt will focus on major scientific frontier issues of blockchain, plan and promote a number of major technology application and industrial development projects, and build a complete blockchain industry ecosystem. For example, the Municipal Economic and Information Technology Commission will support key blockchain companies to carry out key core technology research. The Municipal Big Data Development Bureau will use high standards to promote the city’s blockchain industry into the fast lane.
In terms of industrial layout, we will rely on Yuzhong District and Liangjiang New District to attract a group of blockchain companies with strong innovation capabilities and great development potential to set up R&D centers and corporate headquarters. Relying on the High-tech Zone and the Western (Chongqing) Science City to build the Chengdu-Chongqing Blockchain Science and Technology Innovation Corridor, and promote the application pilot of "blockchain + professional fields" in various districts and counties.
In terms of independent innovation, efforts will be made to improve the sustainable innovation capabilities of blockchain technology and build an open, inclusive and dynamic blockchain innovation environment. For example, the Municipal Science and Technology Bureau will continue to strengthen scientific and technological support and promote the establishment of blockchain innovation service agencies. Yubei District will strengthen government planning and guide market entities to transform from "Internet thinking" to "blockchain thinking".
In terms of integrated application development, our city will focus on promoting the deep integration of blockchain with the real economy, deep application in the financial field, and wide application in public services and people's livelihood fields. For example, the Municipal Agriculture and Rural Affairs Committee will accelerate the innovative development of blockchain + smart agriculture and promote the high-quality development of digital agriculture in the city. The Chongqing Business Management Department of the People's Bank of China will explore and carry out more pilot application scenarios to serve cross-border settlement and facilitate investment and financing.
⑨ Does the country support blockchain?
As a new technology, countries around the world have corresponding policies to support its development, with a wide range of radiation - from this year's perspective 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 National Internet Information Office is responsible for the nationwide blockchain information services in accordance with its duties.Supervise and manage law enforcement work. 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.
