① How to apply blockchain How to apply blockchain

1. Financial field:
Blockchain is used in international exchange, letters of credit, equity registration and securities Exchanges and other financial fields have potentially huge application value. The application of blockchain technology in the financial industry can eliminate the need for third-party intermediaries and achieve direct point-to-point connection, thereby greatly reducing costs and quickly completing transaction payments.
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. This field is considered a promising application direction of blockchain.
3. Public service field:
Blockchain is closely related to people’s production and life in public management, energy, transportation and other fields. However, the centralized nature of these fields also brings some problems. Blockchain can be used chain to transform. 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, proving the existence of text, video, audio and other works, and ensuring the authenticity and uniqueness of ownership. After the rights of the work are confirmed on the blockchain, subsequent transactions will be recorded in real time, realizing the full life cycle management of digital copyright and also serving 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, Can Tan Orange does not require the policy holder to apply or the insurance company to approve it. As long as the claim settlement conditions are triggered, the policy will realize automatic claim settlement. A typical application case is LenderBot, which was launched in 2016 by the blockchain company Stratumn, Deloitte and the payment service provider Lemonway. It allows people to register customized micro-insurance products through the chat function of Facebook Messenger to provide insurance 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. Relevant information in the public welfare process, such as donation projects, fundraising details, fund flows, recipient feedback, etc., areIt can be stored on the blockchain and transparently and publicly disclosed conditionally to facilitate social supervision.

② In which fields is blockchain suitable for application?

The first one is the information security industry.
The second one is the bill business field
The third one is the payment and settlement business.
Fourth, identity/account authentication business.
Fifth, each node participating in the maintenance of the equity proof blockchain can obtain a complete data record. Using the characteristics of reliable and collective maintenance of the blockchain, the rights of the owners of equity can be confirmed.
Blockchain technology is really powerful. With the advancement of the times, this technology may change the development direction and trend of the financial industry, and because the blockchain technology itself has large capacity, high-speed computing, security, and convenience And other characteristics have laid a strong foundation for the advancement and popularization of technology.

③ 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, and at its peak, it was worth more than 20,000 US dollars.One has skyrocketed more than a thousand times, which has also benefited a large number of local tycoons. Currently, virtual currencies generated by blockchain technology are increasingly entering everyone's lives. Many people have joined the ranks of currency speculation. I often hear people say that buying the right money One hundred times the coin, a bicycle can be transformed into a sports car, and one coin can turn a young model into a young model. You can imagine how attractive it is.

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 bottom layer of the blockchain addsCryptozoological technology ensures that participants cannot tamper with the ledger, ensuring that transaction records are transparent and secure. Regulators can easily track on-chain transactions 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 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 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 improve data circulation and sharing.play a huge role. 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 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 certificate issuance, as well as the credibility of the identity of the parties. It 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, users can be provided with real-time and reliable confirmation solutions.

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 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" (State Office Letter [2019] 41 No.) document points out the need to optimize services such as witnessing, venues, information, archives, 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 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 bidding corporate financial services

Bidding behavior of biddersScattered in various trading centers, simply aggregating data into a centralized information system involves the risk of data tampering (untrustworthy), and valuable bidder transaction behavior data cannot be safely and reliably aggregated and shared. 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. 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.

The application that has been implemented is product traceability. Alibaba and JD.com are already using blockchain technology to conduct full traceability of some of the products sold., consumers can trace the origin of purchased goods. 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, 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 are exploding, having such a place will be like a magical treasure land.

What can the blockchain do?

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 8000PB. Then if we share the idle information of everyone on the Internet,Woolen cloth?

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 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 service applications that use blockchain technology?

Blockchain technology has a distributed ledger that cannot be tampered with, ensuring the transparency and transparency of information. Sharing, thus significantly reducing the cost of establishing trust and reaching consensus between peers in business activities. This article provides an in-depth interpretation of four typical business scenarios: supply chain finance, commodity traceability, technology and medical care, and industrial Internet.
1. Blockchain adds supply chain finance. Today, the supply chain of most commodities, from the provision of raw materials to the manufacturing of finished products, involves several upstream and downstream small and medium-sized enterprises; and these enterprises are faced with the challenge of unlocking supply chain working capital. pressure. Supply chain finance refers to banks and other financial institutions making systematic financing arrangements for all member companies of the supply chain, thereby forming a win-win situation for core buyer companies and suppliers: the buyer optimizes working capital, and the supplier generates additional operating cash flow, thus Minimize risk throughout the supply chain. There are three pain points in traditional supply chain finance: 1. Information cannot be shared, efficiency is low, and credibility is poor; 2. Bill circulation is inconvenient, contract settlement is slow, and there are often financial risks; 3. Credit cannot be transferred and financing is difficult. The blockchain can realize the following functions: 1. Sharing transaction data, receivables and payables data among core enterprises, multi-level suppliers, and financial institutions while protecting commercial privacy; 2. Transfer of corporate claims and automatic settlement of funds, accelerating corporate recovery. Payment and repayment; 3. The core enterprise's payment commitments flow among multi-level suppliers and financial institutions to convey the core enterprise's credit.
2. Blockchain traceability In the field of commodity traceability, blockchain and Internet of Things technology are combined to trace the entire process of commodity circulation to prevent unscrupulous traders from taking advantage of the information asymmetry in the commodity chain to produce counterfeit and inferior commodities. Shoddy goods. This prevents certain participants from tampering with data or falsely claiming that information is lost when circumstances are detrimental to them, making it difficult to provide evidence and pursue accountability. In addition, blockchain traceability can open up information islands in different links of the supply chain and improve the collaboration efficiency of the supply chain.
3. Blockchain helps medical services Blockchain technology can open up multiple links such as hospital prescription issuance, pharmacist review, drug distribution, drug payment, and process supervision. Through blockchain distributed storage and accurate matching of information on the chain with patients, the one-time dispensing effect of prescriptions is ensured.To prevent prescription modification or abuse, facilitate supervision, etc. In the future, patient information, prescription information, drug circulation information, etc. will be encrypted and desensitized through blockchain technology, which can open up more medical application scenarios.
4. Integration of Blockchain and IoT Industrial Internet At the 5th World Internet Conference, the supET Industrial Internet platform, which integrates Internet of Things and blockchain technology, was selected as the world's leading Internet scientific and technological achievement and became the only The award-winning industrial Internet platform.

In addition, blockchain data sharing, blockchain judicial chain, blockchain charity, trusted digital content copyright services, etc. In industries such as government, finance, industry and logistics, healthcare, retail and the Internet, blocks have a wide range of business application scenarios.

⑤ What are the application examples of blockchain technology

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

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.

Guaranteed price is the concept of a contract. When a customer purchases a package,After the bank signs the receipt normally, the account claim is automatically triggered, the contract ends normally, and the automatic settlement of the premium ends. 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.

⑥ What are the applications of blockchain technology in business

1. Banking industry
A bank is a safe storage warehouse and value exchange center, and blockchain As a new type of digital transaction method, it can prevent financial risks more safely and is even more outstanding in the current financial field. UBS and the British Barclays Bank have successively carried out blockchain research experiments. It is hoped that the cost of settlement middlemen can be reduced through the decentralized ledger characteristics of blockchain technology.
2. Payment and cash transactions
Today’s transaction model has been fixed for hundreds of years. Nowadays, the intervention of blockchain technology is to create a more simplified transaction system, which can create a better future for the existing cash transaction model with the characteristics of decentralization, convenience, borderlessness, ultra-low rates, and instant transaction arrival. "Business Structure".
3. Traceability of academic certificates and training
Using blockchain technology to certify academic certificates will ensure that students’ education and training are traceable. If the future education system can adopt open and transparent academic certificates and results Certificates and diplomas can better solve the problem of academic qualification or certificate fraud, and solve the labor cost and certificate manufacturing cost.
4. Copyright certification
“Traditional copyright protection methods include copyright registration, judicial appraisal and notarization, which are all effective in protecting originality.An effective method, but it is time-consuming and labor-intensive. After traditional media has spent a lot of time and energy producing content, it seems a little helpless when it comes to traditional methods of copyright protection, which consumes as much time and energy as creating content. For example, a single creative product worth several hundred or even dozens of yuan will require hundreds of yuan to be spent on copyright protection, which is unacceptable to many creators.
Through the development of blockchain-based digital rights management (DRM: Digital Rights Management) technology, each authorization license when a work is released or the copyright owner’s copyright of the work is recorded and tracked, allowing the management side to and authors have greater control over their intellectual property. Blockchain technology can help authors, artists, photographers and other art workers register the copyright of their works on the blockchain to prevent infringement.
Blockchain technology provides a simple public database registration, which facilitates creators to register copyright on the blockchain and obtain the corresponding copyright certificate. If someone copies a work without permission, the blockchain will automatically issue a copyright certificate as a warning. It also records all authorized and unauthorized copying and distribution activities, which can be used as management and statistics for the management department and copyright owners, and can also be used as evidence in court for infringement.

5. Public welfare and charity
The characteristics of the blockchain itself are to solve the "trust" problem in charity fundraising. The blockchain is a digital account book that cannot be tampered with. It is based on the block chain. In the transaction model of blockchain technology, there is no central organization or central server. All transactions are recorded in the blockchain distributed database, which means that the donations or benefits raised can be effectively distributed to all parties. The entire process needs to be simpler, safer, more transparent and more authentic in human hands.
Triporg: It is a travel service platform that uses blockchain technology to provide booking services such as air tickets and train tickets.

⑦ What are the applications of blockchain industry?

Taking the tourism industry as an example, blockchain applications are mainly concentrated in travel, travel community reviews, digital identity management, credit consumption management, Tracking pilots' professional certificates and qualifications, hotel and airline loyalty programs, reservation management, and consumer 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.

⑧ 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 shopping online, the biggest worry is buying fake products, especially overseas products, and there are also price issues caused by fakes. 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", unites government departments at all levels to build a Jingdong blockchain anti-counterfeiting traceability platform through the alliance chainTaiwan; in December of the same year, it jointly announced the establishment of China's first safe food blockchain traceability alliance with Walmart, IBM, and the National Engineering Laboratory of E-Commerce Transaction Technology of Tsinghua University.

1. Financial field

Blockchain is used in international exchange, letters of credit, stock rights registration and Financial fields such as stock exchanges have potentially huge application value.

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 centralization of these fields Characteristics also bring some problems, which can be transformed 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. 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.

6. Public Welfare Field

The data stored on the blockchain is highly reliable and cannot be tampered with, so it is naturally suitable for social welfare scenarios.
