1. Blockchain development action plans "Blockchain+" have been issued in many places to show off their potential
p>
[Zhongya Finance] Recently, Hebei, Guizhou, Hunan, Beijing, Guangzhou, Ganzhou and other provinces and cities have issued blockchain development action plans to build blockchain platforms and promote the "on-chain" of enterprises. Planning, the domestic blockchain industry is ushering in rare development opportunities. At present, blockchain technology has been implemented in judicial certificate storage, government affairs management, people's livelihood services, food traceability, supply chain management and other scenarios. In the future, it may show its talents in new infrastructure, industrial chain transformation, public services and other fields, providing high-quality services. Quality development is gaining momentum.
During the epidemic prevention period, Mr. Ma, a Beijing citizen, fell in love with online shopping. After he recently received a box of Anhui Dangshan Su pears, he found a QR code with "Blockchain Traceability" written on the package. Scanning it with his mobile phone revealed the name of the e-commerce company selling the pears, the location of the authentic place of origin, and the product. "Identity" information such as features and quality alliances to which it belongs is clear at a glance, and even the number of QR code scans is clearly displayed. Mr. Ma said: "Seeing such detailed and accurate product information makes me more confident in the quality of the product."
The application of blockchain technology in online shopping has been an active innovation technology application scenario in recent years. an epitome of. According to the "2018-2019 China Blockchain Development Annual Report" released by the China Blockchain Ecological Alliance, blockchain technology is most actively used in the financial field, and has formed an important role in cross-border payments, asset management, supply chain finance, etc. A batch of new products that can undertake actual business; phased results have been achieved in the fields of electronic certificate deposits and charity; and exploration has begun in the fields of medical services, government management, transportation and logistics.
Against this background, many domestic provinces and cities have recently issued blockchain development action plans. In the plan, building a blockchain open innovation platform and promoting the "online" of key enterprises have become the next focus of work in various places. For example, the "Beijing Blockchain Innovation and Development Action Plan" issued by Beijing in early July proposed that by 2022, it will take the lead in forming a "Beijing Plan" for blockchain to empower economic and social development; Guizhou Province issued in early May "About Accelerating District "Opinions on Blockchain Technology Application and Industrial Development" proposes that by 2022, 3 to 5 blockchain open innovation platforms and public service platforms will be built, and more than 100 growing blockchain companies will be introduced and cultivated; Hunan Province will The issued "Three-Year Action Plan for the Development of the Blockchain Industry in Hunan Province (2020-2022)" proposes to build more than 10 blockchain public service platforms by 2022 and promote 30,000 companies to get on the chain; Guangzhou, Guangdong, Ganzhou, Jiangxi It is also proposed to cultivate a number of key blockchain enterprises and promote typical application demonstration scenarios.
During the epidemic, "Add...Code" blockchain technology development. Experts said that since this year, the demand for digital social governance innovation and soft and hard infrastructure construction has increased significantly, and the potential of blockchain technology in the technical transformation of industrial chains and government governance has become more prominent. < /p>
“As more and more people realize and enjoy the convenience brought by digital life, they are more determined to carry out digital reform and Determination to actively 'wind up'. "Pan Helin, Executive Dean of the Digital Economy Research Institute of Zhongnan University of Economics and Law, said that during the epidemic prevention period, blockchain technology has obvious advantages in information management, emergency supplies and food safety traceability, and identity authentication management. For the digital economy or blockchain From a technical point of view, the epidemic is a development opportunity. After the epidemic has spawned a large number of digital demands, blockchain will exert greater power in production and supply chain collaboration, public safety warning, and financing of small and medium-sized enterprises.
Use blockchain technology to build a "virtual factory" for Nankang furniture to trace the origin of Gannan navel orange products... In recent years, Ganzhou blockchain companies have continued to emerge, involving digital licenses, digital bills, anti-counterfeiting traceability, filing and notarization, There are also more and more businesses such as copyright protection and digital finance. To this end, the local area has recently established a blockchain service hall to ensure that these businesses are handled centrally.
< /p>
Some experts said that from a nationwide perspective, attempts to innovate blockchain service models and solve the difficulties of integrating blockchain technology with people's livelihood and the real economy are gradually increasing. As an emerging technology in the digital economy era , blockchain technology also faces many difficulties and obstacles in scientific research and implementation, including technical aspects. Blockchain encryption technology faces technical risks such as inference and even traceability; in terms of implementation, there are problems such as limited application fields and low industrial agglomeration effect. ; In addition, there are bottleneck issues such as lack of professional talents.
Action plans issued in many places also target these difficulties and blocking points. For example, the "Beijing Blockchain Innovation Development Action Plan" puts forward 4 key points Mission: Lead by innovation to build a blockchain theory and technology platform; drive by demand, build and implement a number of multi-field application scenarios; focus on development and cultivate an integrated and linked blockchain industry; ensure factor protection and build a leading blockchain talent echelon.
Affected by the epidemic, the accounting period of downstream engineering projects in some industries has become longer, and the pressure on upstream small and medium-sized suppliers has increased accordingly. This once made some small business owners very anxious, and they did not dare to take on big orders.
How to open up business flow, logistics and capital flow, so that the upstream and downstream of the industrial chain can "turn" together? Zhejiang's The approach is to build a blockchain receivables chain platform. This platform puts the accounts receivable accumulated in the supply chain online as "blockchain receivables", solving the risk of fraud that is difficult to prevent in traditional receivables financing. Upstream suppliers Receive the blockchain issued online by the supply chain enterpriseThe receivables can be transferred to the bank for cash on the same day, eliminating the need for cumbersome procedures such as underwriting and signing, witnessing and confirming rights, and the "hardened" funds between the upstream and downstream of the industrial chain are revitalized.
Currently, blockchain applications are still in the early, niche and trial stages. With the implementation of 5G technology, the increase in market data volume and the improvement of technical issues, more application cases are expected to appear in the future.
Experts said that in order to achieve safe and sustainable development of blockchain technology, we must first solve the technical problems, especially the realization of technical security, decentralization, scalability and other issues, which requires all parties to Cooperate fully; secondly, we must promptly pass legislation to protect the legal issues that may be faced during the development of blockchain technology, and at the same time severely crack down on the use of blockchain technology to commit illegal crimes.
2. What are the applications of blockchain in the industry?
Take the tourism industry as an example. Blockchain applications are mainly concentrated in travel, travel community reviews, digital identity management, and credit consumption management. , tracking pilots’ professional certificates and qualifications, hotel and airline loyalty programs, reservation management, and consumption points management are several application areas. In addition, with the development of blockchain, many related top domain names have been registered, which has had a relatively large impact on the domain name industry. In addition, blockchain also has applications in finance, games, entertainment and other fields.
3. 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 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. Finally, all nodes around the world will complete the transaction according to a certain mechanism.Synchronize again and again 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 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 on-chain transactions 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 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 concentrate 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 rights, the rights of text, pictures, audio and video, etc. can be confirmed through digital signatures of blockchain technology and on-chain certificates.Smart contracts create and execute transactions, allowing creators to regain pricing power, preserve data in real time to form an evidence chain, and cover 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 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 during the real-time solidification process. electricitySub-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 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 characteristics of the distributed ledger 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 can ensure the authenticity of the data transfer process on the chain, within the regional alliance The bidder's performance is directly taken from the on-chain data, making it impossible to hide 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. Due to its centralized characteristics, the traditional digital witness system is prone to data tampering, 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 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 enterprises
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 aggregated and shared through the blockchain, the performance of different bidders can be analyzed.It provides different guarantee rates for different bidders, 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 contracts and keep promises, and maintain Bidding market order.
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 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. 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. due to credit salesThe supplier's capital shortage problem 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 cost of raw materials or intermediate products, and ultimately increase the number of bidders profit margins and indirectly reduce the cost of the tenderer.
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 infancyAt this stage, the technology is not mature enough, but it is also the best 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. Therefore, in the Internet, a place where data and information explode, 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. . From digital currency to securities and financial contracts, medical care, games, and artificial intelligence, smart contracts, Internet of Things, e-commerce, file storage and other fields can be widely used.
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.
4. What are the application fields of blockchain technology?
Answer: The application fields of blockchain technology
1. Financial field
Blockchain has potential huge application value in financial fields such as international exchange, letters of credit, equity registration and stock exchanges.
2. Internet of Things and Logistics Fields
Blockchain can also be naturally combined in the Internet of Things and logistics fields.
Through blockchain, logistics costs can be reduced, the production and delivery process of items can be traced, and the efficiency of supply chain management can be improved.
3. Public service fields
Blockchain is closely related to people’s production and life in public management, energy, transportation and other fields, but the centralized nature of these fields also brings Some problems can be solved using blockchain.
4. Digital copyright field
Through blockchain technology, works can be authenticated, prove the existence of text, video, audio and other works, and ensure the authenticity and uniqueness of ownership. sex.
5. Insurance field
In terms of insurance claims, insurance institutions are responsible for fund collection, investment, and claims settlement, and often have high management and operating costs.
6. Public welfare fields
The data stored on the blockchain is highly reliable and cannot be tampered with, so it is naturally suitable for use in social welfare scenarios.
5. What are the current applications of blockchain?
What is blockchain technology? People in each industry have different understandings, and relevant explanations are gradually emerging due to more and more real-life applications. With the popularization of this blockchain technology, the related results are getting bigger and bigger. If we want to understand this technology, we must have an in-depth understanding of reality.
my country’s current economic and social credit environment is still relativelyWeak and high credit costs, blockchain technology proposes a set of lower-cost "trust" solutions to reduce the credit costs of the whole society, which is of great significance to promoting the development of my country's credit economy. Although this technological innovation in the field of Internet finance is not yet mature, many large banks in the world have rushed to invest resources in research and development, which should attract the attention of my country's banking industry and regulatory authorities.
(1) As for commercial banks, they should prepare technology and talent reserves and actively participate in the formulation of international standards.
In order to prevent digital currency risks, my country’s commercial banks are currently unable to conduct digital currency transactions, and the research on technological innovation behind digital currencies is also lagging behind. This is slightly asymmetrical with my country’s private enthusiasm for blockchain research and development. . Nowadays, the development of emerging models of disintermediation such as blockchain technology and P2P is gradually moving from concept to application, driven by the joint innovation of large global financial institutions. my country's major banks should also pay close attention to the latest innovation trends of international peers and join the research as soon as possible. , develop the ranks of blockchain products and promptly adjust development strategies to adapt to the business operation model of Internet finance under the new situation. First, it can establish a research and development laboratory or cooperate with financial technology companies. In addition to developing different blockchain application scenarios, it can also be combined with national conditions and inclusive finance, such as studying how to use blockchain technology to achieve low-cost fund transfer payments in economically underdeveloped areas and improve financial services in these areas. The second is to actively participate in the formulation of international standards and agreements, strive for the right to speak, and avoid being a passive follower.
(2) Regulatory agencies also need to continue to pay attention to the development of the latest Internet technology and be prepared to respond.
First, the "decentralization" brought by blockchain technology does not mean that centralized organizations are not needed in economic operations. Blockchain technology hopes to break privileges and human manipulation and allow computer algorithms to achieve "free credit notarization." But from a practical point of view, theoretical deductions cannot be completely mapped to real life. For example, due to the lack of supervision, digital currency transactions such as Bitcoin face high risks of speculation and money laundering. Therefore, if blockchain technology wants to become a new channel for capital circulation, it needs supervision and implementation standards to protect the interests of all parties in the market. In this regard, regulatory authorities should formulate relevant standards and specifications, especially operating specifications, and use their power to ensure that financial innovative products are used rationally; at the same time, they should also improve the protection of consumer rights and interests, strengthen education on the protection of financial consumer rights and interests, and improve consumer awareness. Risk prevention awareness. In short, even in a "decentralized" business system, centralized departments are needed to provide normative and guarantee support.
Second, regulatory authorities must be prepared to respond to possible changes in regulatory methods. At present, new technologies have a profound impact on the monetary systems of various countries, and the traditional policy framework and means of regulating economic and financial affairs are increasingly unable to keep up with the changes in the situation. Regulatory authorities should keep pace with the times and make full use of the convenience of financial technology to improve supervision methods and improve supervisory means. For example, if securities lending, repurchases, and margin trading can all be traded through transparent and open blockchains in the future, then regulatoryDepartments can consider using the information from this public ledger to monitor systemic risks in the market, which is not only efficient but also reliable.
Third, regulatory agencies can proactively embrace new technologies in Internet finance. Central banks can respond in two ways to a financial landscape transformed by technology: monitor and respond to developments or take a proactive approach. U.S. Securities and Exchange Commission member Kara Stein believes that regulatory agencies need to be in a leading position to take advantage of the advantages of blockchain technology and respond quickly to its potential weaknesses. The Bank of England's research further stated that the central bank may consider issuing blockchain-based digital currencies in the future, which if done properly can increase financial stability.
Blockchain was first launched and recognized by people to support the formation and circulation of Bitcoin. However, unlike the controversial Bitcoin, the introduction of blockchain technology has adapted to the development of the Internet. After entering a new era of mobile Internet, Internet of Everything, and anytime Internet, a large number of online transactions are in urgent need of party identity verification and transaction confirmation. , greatly improve the efficiency of transaction settlement and clearing, and ensure the urgent needs of funds and information security. Therefore, blockchain technology has received increasing attention and attention, and attracted more and more people to explore, innovate and apply. .
By the end of 2015, more than 20 of the world's top financial institutions have begun to explore the application of blockchain technology at the financial level. More and more people believe that blockchain technology uses new encryption authentication technology and decentralized mechanisms to maintain a complete distributed, non-tamperable, continuous ledger database, which allows participants in the blockchain to The security of funds and information is ensured through a unified ledger system without the need for mutual recognition and trust. This is of extremely great significance to financial institutions and financial innovation.
First, blockchain technology can reduce trust risks.
Blockchain technology is open source and transparent, and system participants can know the operating rules of the system. Under blockchain technology, since each data node can verify the authenticity and integrity of the ledger content and ledger construction history, it ensures that the transaction history is reliable and has not been tampered with, which is equivalent to improving the accountability of the system. , reducing the trust risk of the system.
Second, from an enterprise perspective, Bubi blockchain has been used in equity, supply chain, points and other fields, and is conducting trials and application tests with exchanges and banks. Bubi Blockchain focuses on the innovation of blockchain technology and products. It already possesses a number of core technologies and has developed its own blockchain service platform. And many blockchain innovative and entrepreneurial companies are constantly emerging.
Third, blockchain can drive the birth of new business models.
The characteristics of blockchain technology enable it to realize some business models that are difficult to achieve in a centralized model. For example, in the Internet of Things industry, some organizations have proposed using blockchain technology to manage the identity, payment and maintenance tasks of tens of billions of Internet of Things devices. Using blockchain technology, the Internet of ThingsNetwork equipment manufacturers can significantly extend the life cycle of products and reduce the cost of IoT maintenance.
Fourth, blockchain technology has a flexible architecture.
Based on different application scenarios and user needs, blockchain technology can be divided into several types: public chain, private chain and alliance chain, which can be selected according to the actual use of the organization.
Fifth, blockchain technology is a beneficial tool for realizing shared finance.
The essence of shared finance is to achieve the purpose of optimizing the allocation of financial resources by reducing the asymmetry of financial information, and through strict third-party certification and supervision mechanisms to ensure the implementation of the rights and interests of both parties to the transaction and facilitate the completion of the transaction. By using blockchain technology, financial information and financial value can be more strictly protected, enabling more efficient and lower-cost flows, thereby realizing the sharing of value and information.
Sixth, the openness of blockchain technology encourages innovation and collaboration.
Through the openness and collaboration of source code, blockchain technology can promote collaboration among different developers, researchers, and institutions and learn from each other's strengths to achieve more efficient and safer solutions. In recent years, many overseas financial institutions and commercial institutions have tried to use blockchain technology to improve business models. In China, although this technology has not yet been widely recognized and applied, it has begun to attract more and more widespread attention. Attention, its influence is rapidly increasing. Now blockchain technology has been regarded as one of the basic protocols for the next generation of global credit certification and value Internet. The importance of blockchain technology to my country's financial industry and financial system cannot be ignored.
Of course, we must know that the development of blockchain technology is still in its early stages globally, and various technical solutions, application scenarios and business models need to be further explored and improved. Especially in our country, blockchain is a brand-new concept and theory, and people's cognition, research and practice have just begun. If we want to overtake in this field, catch up with the advanced, and lead the world, we still need enough attention. More investment requires the active investment and positive interaction of theoretical researchers, network technicians, financial practitioners, and regulatory authorities, and the courage to explore and innovate.
What is blockchain technology? People will definitely understand more and more about such technology, and it will play an increasingly important role in reality, and will be supported by many institutions, thus bringing the popularization of blockchain into a new application stage in reality.
6. How to apply blockchain How to apply blockchain

3. Public service field:
Blockchain is closely related to people’s production and life in public management, energy, transportation and other fields, but the centralized characteristics of these fields are also It has brought about some problems that can be transformed using 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 Tampered, you can monitor the status and integrity of the software, detect bad tampering, and ensure that the data transmitted by systems using IoT technology has not been tampered with.
4. Digital copyright field:
Through blockchain technology, works can be authenticated, prove the existence of text, video, audio and other works, and ensure the ownership of works. Authenticity and uniqueness. 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, MineLabs, 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.
5. Insurance field:
In terms of insurance claims, insurance institutions are responsible for fund collection, investment, and claims settlement, and often have high management and operating costs. Through the application of smart contracts, there is no need for the policy holder to apply or the insurance company to approve it. As long as the claim settlement conditions are triggered, the insurance policy can automatically settle claims. A typical application case is LenderBot, which was launched in 2016 by blockchain companies Stratumn, Deloitte and payment service provider Lemonway. It allows people to register customized micro-insurance products through the chat function of Facebook Messenger, providing services between individuals. The high-value items exchanged are insured, and the blockchain replaces the third-party role in the loan contract.
6. Public welfare field:
The data stored on the blockchain is highly reliable and cannot be tampered with, so it is naturally suitable for use in social welfare scenarios.
