❶ What are the applications of blockchain education

There are many directions for integrating blockchain into education. my country’s “China Blockchain Technology and Application Development White Paper” and the European Commission The report "Blockchain in the Education Industry" has conducted a preliminary discussion on the application model of blockchain in the field of education.
The application models of blockchain in the field of education mainly include:
Intelligent transactions create an educational Taobao platform based on smart contracts, build communities to achieve true "self-organizing" operation of online learning communities, and non-school educational institutions join Multiple themes in the market jointly participate in the formulation of educational content and establish an accessible individual academic credit database to solve the global problem of academic fraud.
Online education branches are very broad, and the ecological structure applied to each branch is also different. Existing online platforms should seize opportunities for ecological optimization, not only in their own market segments, but also in achieving continuous optimization in the entire online education market.

The Xueshuo Innovation Blockchain Technology Workstation under Lianqiao Education Online is the only “blockchain technology workstation” approved by the “Smart Learning Workshop 2020- Xueshuo Innovation Workstation” carried out by the School Planning and Construction Development Center of the Ministry of Education of China. "Technical Professional" pilot workstation. The professional base is based on providing students with diversified growth paths, promoting the reform of the training model integrating professional degree research, production, and research, and building an applied and compound talent training system.

❷ Why Xing Shuai said that blockchain will reshape online education

As a brand-new technical system and concept, blockchain is being favored by society and capital. As the "coin speculation craze" subsides and blockchain matures, more and more people are paying more attention to the practical application of "blockchain+". Xing Shuai, an investor in Zhidou Education and founder of Xing Shuai Education, recently said that blockchain will reshape online education, and policy support is the biggest reassurance.

It is reported that the transparency of the blockchain system and the non-tamperability of data are fully applicable to student credit management, further education and employment, academics, qualification certification, industry-university cooperation, etc. In terms of aspects; blockchain can also solve many challenges in the education industry, such as digital authentication, multi-step authentication, identification and transfer of credits, and student payment transactions, etc.

“We hope to use blockchain to change online education and make learning a kind of productivity.” JACKY, technical director of Smart Bean Education Chain (SOW), said that Smart Bean not only has many years of rich experience in the online education industry The experienced Zhidou Education Chain team also has cooperation traffic with nearly tens of millions of online education users.

After more than ten years of development, online education has become increasingly mature, but there are still many common problems that have not been effectively solved, such as easy information fraud, weak copyright protection, high operating costs, and difficulty in resource sharing. "Blockchain, which happens to have the characteristics of being open and transparent, and the information on the chain cannot be tampered with, can solve these problems from the source." Xing Shuai said.

In Xing Shuai’s view, the previous online education only changed the way teachers teach and students learn., there is no need to travel across mountains and rivers, and there is no need to go out of the house, but it does not really change the motivation problem of learning. “Now applying blockchain to online education can greatly improve the motivation for learning. It is changing our education model that has not changed for thousands of years. In today’s era of knowledge explosion, it can achieve extremely high learning completion rates. Big improvement."

❸ What are the application examples of blockchain technology

The express logistics industry is very suitable for the application of blockchain Chain technology industry.

In fact, the logistics ecosystem is relatively complex and there are many groups involved in the process.

The industry itself is a complex of segments with the concept of "flow". Starting from the initial "business flow", it gradually gave birth to "logistics", as well as the corresponding support of "capital flow" and "information flow" , complete the service chain.

There is a key issue behind the emergence of various "flows", which is the transfer of commodity ownership.

Coincidentally, many of the types of problems solved by blockchain technology are related to the trust friction generated during the transfer of asset ownership.

The application of blockchain technology can significantly improve the processing speed and efficiency of settlement business in the express logistics industry, effectively solve the problem of traceability and anti-counterfeiting of items, and fully ensure information security and the privacy of senders and recipients.

In the field of promoting application in the express logistics industry, there are domestic blockchain companies doing applications in this area, such as Walton Chain.

Last year, Waltonchain reached a strategic cooperation with Huodou (Xiamen) Technology Co., Ltd., using Waltonchain’s “RFID blockchain” technology solution to help it improve its logistics solutions and move goods to Dou puts data on the chain in all aspects of its logistics turnover, such as entering and exiting the warehouse, receiving goods and other key nodes. After deploying the reading and writing system, when the object passes through any link, the relevant data can be read by the RFID reader and writer, and the relevant data can be read by the RFID reader. The corresponding behavior is converted into data and uploaded to the blockchain. Users can trace the entire logistics process with one click.

Four business scenarios that can be implemented in the real environment are suitable for the application of blockchain technology.

Scenario 1: Insured express delivery

Revolving around the insured scenario, express companies transport goods, insurance companies provide guaranteed goods, merchants provide goods sales, sellers purchase insured services, and the government regulates the industry.

So, what should be recorded on the blockchain? There are several key points. The logistics details of the goods, accounts, identities, claims, other reference data and other information are recorded on the blockchain.

Insured price is the concept of a contract. When the customer signs for the package normally, the account claim is automatically triggered, the contract ends normally, and the premium is automatically cleared. If there is a problem or missing piece, the insurance company's claim process will be triggered.

Scenario 2: Charity express delivery

For charity activities, such as the "One Cent" campaign, one cent from the cost of each charity package is donated to the account of the charity organization .In this scenario, the express delivery company is still responsible for the transportation of goods, the public welfare organization provides the execution of public welfare activities, and the poverty alleviation merchants provide the sales of public welfare and poverty alleviation products.

Then what is recorded in the blockchain is the logistics details of the goods. After the package is signed for, it will be recorded on the blockchain, automatically triggering the transfer from the logistics company's public welfare account to the public welfare organization's account. When the public welfare activities are completed, the entire process is open and transparent, which avoids the public's distrust of social welfare activities.

Scenario 3: Industry blacklist sharing

At present, the blacklist of express delivery employees is still mainly offline. We hope that through blockchain technology, each company can record the blacklist of employees on the blockchain, and other companies can also query it, and the data cannot be modified, and can be traced back to which company this person worked in What kind of inappropriate behavior and other information.

Scenario 4: Supervision of safety incidents in postal delivery channels

Many express companies will install security inspection machines, and the government also wants to know whether each logistics company has any transportation safety hazards. Through the distributed accounting model, each express delivery company can record the effective information of the security incident on the blockchain when a security incident occurs, so that regulatory agencies can monitor it in real time and cannot be tampered with.

❹ What are the application examples of blockchain?

1. Judicial evidence storage

On September 18, 2018, the Hangzhou Internet Court was officially launched on the chain. Became the first court in the world to use blockchain for trial.

It is understood that the complainant can submit electronic evidence such as the contract, rights protection process, service process details, etc. online through the online complaint portal to nodes on the chain such as notary offices, judicial appraisal centers, CA/RA institutions, and courts. Come and witness and endorse together to provide one-stop service for the prosecutor. The Internet Court of Hangzhou, Zhejiang Province made a public judgment on a dispute over infringement of the right to disseminate work information online, and for the first time confirmed the legal validity of electronic data stored using blockchain technology.

2. Logistics field

In early 2018, Cainiao and Tmall International jointly announced that they have used blockchain technology to track, upload, and verify the logistics of cross-border imported goods. Link information.

After all nodes in the logistics chain are connected to the blockchain, the goods will be traceable from the manufacturer to the consumer, forming a complete chain; the more links the goods are missing, the more fake they will be exposed. Product probability is greater.

3. Electronic invoices

On August 10, 2018, Shenzhen Guomao Revolving Restaurant issued the country’s first blockchain electronic invoice. It is understood that this issued block The chain electronic invoice is led by the Shenzhen Municipal Taxation Bureau and Tencent provides underlying technology and capabilities.

Different from traditional electronic invoices and simple electronic invoices uploaded to the chain, this blockchain electronic invoice combines "fund flow and invoice flow" into one, integrating invoice issuance and The combination of online payment simplifies the entire process of invoice application, invoicing, reimbursement, and tax filing.

About the DistrictThere are many practical applications of blockchain, and you can learn more about them.

❺ Can the penetration of blockchain technology promote the transformation of traditional education

The birth and development of blockchain provide some opportunities to solve the problems of traditional education and Internet education. Introducing traffic by matching educational

educational resources, and then using the dividends to form a virtual currency ecosystem for secondary market transactions or consumption in the social circle will be leveraged by the blockchain A way in the field of education.

Before talking about blockchain technology and applications, let us first review a story. Through the

thinking derived from this story, we begin to outline and outline the relationship between blockchain and Those things that combine with the education industry.

The Byzantine Generals Problem is a matter of agreement. The generals of the Byzantine Empire must unanimously decide

whether to attack a certain enemy army. The problem is that these generals are geographically separated and there are

traitors among the generals. Traitors can act at will to achieve the following goals: trick certain generals into taking offensive action; facilitate a decision that not all generals agree with, such as facilitating an offensive when the generals do not wish to attack; or confuse

Confusing certain generals so that they cannot make decisions. If the traitor achieves one of these objectives, the outcome of any attack

operation is doomed to failure, and only a fully unanimous effort can lead to victory.

Mathematicians designed a set of algorithms: after receiving the information from the previous general, the generals add their own signatures

and then transfer the names to others except themselves. In addition to other generals, such information modules form a blockchain.

The purpose of blockchain: to verify the validity of information

The definition of blockchain: decentralized trust mechanism

The following two pictures Comparing the pictures, the picture above shows the existing centralization method, and the picture below shows the decentralization method of blockchain technology

. In layman's terms, the blockchain is a general ledger that contains all historical transactions. Each block contains several

transaction records. If the blockchain is a ledger, then a block is each page of the ledger. The details of the transaction

are recorded in a public ledger that can be seen by anyone on the network.

Xiao Q once analyzed the market

in the article "A Brief Analysis of Opportunities and Problems in the Online Education Industry: We Still Have These Opportunities":

A large number of high-quality educational resources are not informatized, and there is a lack of unified platform management of educational resources, which makes drainage difficult

Difficult, poor promotion, and insufficient application are not conducive to learning and sharing; already Information education resources are relatively scattered

and have not been systemized; especially in third- and fourth-tier cities, demand from both ends of the supply chain is strong, and students in third- and fourth-tier cities

The demand is strong, but excellent local teachers are limited.

It can be seen that there is a core pain point in the education industry:

Excellent resources (education resources) and excellent students (parents) are the two major entry points for education. .

The emerging blockchain technology may be able to alleviate these two major pain points. Let’s take a look:

Help students with good records to obtain more incentives for Employing universities provide real and reliable student resources

. Achieve a seamless connection between student skills and social employment needs, and effectively promote cooperation between schools and enterprises.

Realize face-to-face recruitment with offline recruitment, making the online resource matching process more direct and simple.

The "decentralization" feature of the blockchain can appropriately open up the originally closed resource pool. Strip away some of the benefits that the resource matching platform can derive from

and allow direct "dialogue" between supply and demand. Whether it is an internship before graduation

or employment after graduation, or a junior high school or a junior high school, it is a two-way choice, and we strive to optimize the resources

process.

For example: The cost of cross-border remittances is high. Through blockchain technology, small foreign financial institutions

can be absorbed into the self-built ecosystem and the interest rates of overseas remittances can be adjusted. Cost Control.

Principle: Using the distributed ledger technology of blockchain, eliminating the manual processing steps of intermediaries and bank staff

, inter-bank transfers become bank point-to-point blockchain technology.

Benefits: Blockchain can avoid complicated systems and create a more direct

payment process between payers and payees, whether it is domestic transfers or cross-border transfers. Cross-border transfers are low-cost, fast

and do not require intermediate fees.

Example: Cooperation between schools and enterprises, linking the student status system and the certification system, making students’ 3-4 years of college study results and courses online, and using district Blockchain builds real and reliableCertification System.

Principle: The learning data is completely recorded in the digital classified "ledger". Once the "ledger" is encrypted, it

cannot be modified or modified. This ensures the privacy and security of student information and reduces the risk of false

.

Benefits: Students' grades and credit completion progress can be placed in the certification system and will not be changed permanently.

At the same time, the school’s student status is linked to the recruitment of enterprises and institutions. Through the certification system, students’ entire learning situation and quality in colleges and universities can be understood, and the information should be disclosed and true to increase employment opportunities for employers. .

❻ The value of DSCPL highlights the new model of “education + blockchain” to solve chronic problems in the industry

DSCPL (DISCIPLINA) is the first to create verified profiles based on academic and professional achievements Multifunctional Blockchain is a multifunctional blockchain platform in the fields of education and recruitment. DISCIPLINA will store the entire history of a person's academic achievements in the blockchain, generating their individual scores. This will allow recruiters to streamline candidate searches based on their required expertise and skills. DISCIPLINA blockchain architecture is designed to solve problems in the education and recruitment sectors. DISCIPLINA will store confidential information such as courses, student assignments, grades and test results. Therefore, public blockchain solutions (e.g., Ethereum or Cardano) that store all transactions in open access are unacceptable. At the same time, private blockchain solutions like Hyperledger fail to provide sufficient verifiability of the data stored on them.

In the past two months, the teaching aid industry, whose main business is off-campus training, has ushered in intensive supervision. From the administrative penalties imposed on top educational institutions such as Gaosi, GSX, and Xueersi, to the establishment of the Off-Campus Education and Training Supervision Department by the Ministry of Education, off-campus education and training is at the forefront.

In fact, before the policy was introduced, the development of education eventually turned into vicious competition and involution, allowing many extracurricular institutions to profit from it, thereby losing the original intention of education. Only by staying true to the original intention can we achieve success. All the time, many educational institutions are spreading uncontrollably like weeds, which seem to have affected the essence of education. The increasing learning pressure has made parents of students very worried.

In this chaotic situation of training institutions, the education sector has introduced a series of policies in a timely manner, such as the double reduction policy, which not only requires schools to reduce the learning burden of students, but also imposes restrictions on off-campus training institutions. For rectification, those training institutions without teaching qualifications were suspended for rectification, and all kinds of training institutions were also closed down one after another.

In the future, cram schools and training institutionsYou must also have teaching qualifications, and the relevant procedures must be complete. Although there is no explicit prohibition on opening cram schools, cram schools cannot collect expensive tutoring fees at will like before. Under the influence of various factors, many Parents expressed less willingness to participate in cram schools.

The transformation of off-campus education and training is urgent. From regulatory authorities to off-campus education and training, everyone is looking for breakthrough points. The introduction of blockchain technology in the education industry has become a new attempt for some education companies. Applications such as the certification of educational qualification certificates and academic certificates, knowledge copyright protection, and supervision of off-campus education funds are currently popular application scenarios.

Education + Blockchain Application Scenarios

In view of the current off-campus education and training market, there are relatively prominent false propaganda, inconsistent qualifications, high pricing, difficult refunds, and money-losing. , blind expansion and other pain points, DISCIPLINA relies on core blockchain technology to effectively realize information exchange between government departments, training institutions, banks, insurance, parents, etc. on the nodes on the chain, and monitor the entire process of course purchase transaction information, capital flow, operating status, etc. Data is uploaded, fixed, and certified to ensure that the data is authentic, credible, and traceable. Through data traces, the credit status of education and training institutions is conveyed, a risk prevention mechanism for the whole society to participate is established, a closed-loop management model is formed, the comprehensive supervision capabilities of the education and training industry are improved, and a full ecosystem of integrated education and training is built.

None of the current existing solutions/platforms meet the goals of DISCIPLINA. DISCIPLINA will store confidential information such as courses, student assignments, grades and test results. This data needs to remain confidential but must also be transparent. At the same time, private blockchain solutions such as Hyperledger fail to provide sufficient verifiability of the data stored on them. DISCIPLINA therefore combines private and public parts, verifies the data provided and provides it to recruiters using smart contracts.

There are advantages for both students and job seekers using this platform. The platform helps analyze the skills and experience required for applying for a job, formulate a career development education plan and create a career plan for your ideal company. Storing this data facilitates communication between job seekers and recruiters and reduces the cost of finding employees for recruiters.

❼ What are the application examples of blockchain technology

Application of blockchain technology in voting
Kuaishang is the first country to apply blockchain technology to In the field of voting, it effectively solves the problem of trust in voting data, provides the most authentic and effective data to activists, and protects the rights and interests of real voting users. At the same time, it makes blockchain technology "people-friendly" and allows the general public to quickly perceive and enjoy the area in the field of life services. The convenience brought by blockchain technology.
Application of blockchain technology in digital asset registration

Ant Blockchain has already had multiple production-level applications, applying leading technology to people's livelihood and business. , finance and other fields.

❽ What are the applications and successful examples of blockchain?

Blockchain can be applied to all walks of life. Taking e-commerce as an example, in order to solve the problem of counterfeit goods, Regarding pain points in logistics, integrity, supervision, etc., major companies and platforms are also showing off their skills and tricks. Blockchain is used as one of the more feasible means, so how does it solve these problems?

First, supervise the production process of goods. When visiting online stores, the biggest worry is buying fake products, especially overseas products. In addition, there is also the price problem caused by fake products. How to buy products at reasonable prices while ensuring the authenticity is really a headache. The transparency and irreversibility of blockchain technology allow consumers to check the production place, manufacturer, raw materials, etc. of goods at any time.

Second, trace and track the transportation of goods. A series of operational activities such as supply chain, inventory, and logistics involved in e-commerce will involve multiple intermediaries. The decentralized, non-tamperable, and traceable characteristics of blockchain make the entire process transparent, and any partner can You can check the inventory and payment status, which can effectively solve the "bullwhip effect" problem in the supply chain. (Bullwhip effect: refers to a phenomenon of demand variation amplification in the supply chain. The fundamental reason for its occurrence is the lack of communication and trust mechanisms between upstream and downstream enterprises in the supply chain. Demand information is transmitted upwards along the supply chain. Keep misinterpreting.) At the same time, blockchain’s smart contracts can be used to regulate intermediaries, such as logistics and payment management partners. Simplify the huge management system to improve efficiency.

Third, guarantee product sales and after-sales service. At present, three-quarters of the transactions in China's e-commerce market are completed on the mobile terminal. Payment trust is a major problem that the platform needs to solve, and blockchain is known as a "trust machine." To give you an example, many websites Stores will fake orders or falsify data in order to get good reviews. Once the purchase information is uploaded to the chain, it cannot be tampered with to ensure authenticity. You can check the merchant's real transaction records to ensure whether the merchant is trustworthy.

Fourth, protect user privacy. The private key, public key, and encryption algorithm of the blockchain can solve this problem. Each user has his own independent address, and due to the anonymity of the blockchain, companies cannot publish or store user information and are protected from hackers. s attack.

For specific implementation, we take the two domestic e-commerce giants as examples. Alibaba has begun to introduce blockchain since 2016. First, Ant Financial launched blockchain technology to pay for charity donations, which was the first test of blockchain technology; in 2017, Ant Financial’s technology experiment The Office announced the opening of blockchain technology to support imported food safety and product authenticity traceability; in 2018, Cainiao and Tmall International announced the use of blockchain technology to track and verify the full logistics information of cross-border imported goods. These data include goods The country of origin, country of shipment, loading port, mode of transportation, import port, bonded warehouse inspection and quarantine order number, customs declaration number, etc.

Logistics and product traceability are indeed a good entry point for blockchain to enter the e-commerce field. As one of the domestic e-commerce giants, JD.com is certainly not to be outdone. In 2017, JD.com announced the establishment of " Jingdong Quality Traceability Anti-Counterfeiting Alliance", united government departments at all levels to build a Jingdong blockchain anti-counterfeiting traceability platform through the alliance chain; in December of the same year, it jointly announced the establishment of the China National Engineering Laboratory for E-commerce Transaction Technology with Walmart, IBM, and Tsinghua University The first safe food blockchain traceability alliance.
