⑴ What are the application examples of blockchain technology
The express logistics industry is a very suitable industry 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 the 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 written. 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: Public welfare express delivery
For public welfare activities, such as the "One Cent" campaign, donate one penny from the cost of each public welfare package to the account of the public welfare 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. After the public welfare activity is over, the whole process isBeing open and transparent avoids public distrust in 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.

⑶ What is the popular explanation of blockchain? You must know these five application scenarios of blockchain!
Recently, blockchain has become popular overnight, and everyone around is discussing blockchain.
So, is the blockchain the same as Bitcoin?
In fact, Bitcoin and blockchain are not the same thing.
Blockchain is the underlying technology of Bitcoin, but the firstThe first use case is Bitcoin.
Bitcoin is just a string of data in a computer. Compared with paper currency, it is also called a "virtual currency". To put it simply, you can understand that Bitcoin is just a string of numbers with cash value, similar to Q coins. In other words, Bitcoin has no actual value. Its current value is supported by the faith of currency speculators. If the faith is gone, the value of Bitcoin will collapse.
What is blockchain? What are the characteristics of blockchain technology?
Let’s first take a look, why is blockchain called blockchain?
Data is stored piece by piece, and the data stored piece by piece is called a block. Different blocks are linked to the previous block, which is called a blockchain.
For example:
On a certain day of a certain year, Lao Wang lent Xiao Wang 10,000 yuan. Lao Wang told everyone around him the news , the transfer records were posted on WeChat Moments, and everyone helped them testify to the existence of this transaction.
Lao Wang and Xiao Wang are two nodes. These two nodes generate transaction time, location, person and other information, and they are packaged to form a "block". Lao Wang’s friends are also nodes. These nodes jointly record the transaction status and details (blocks) of the two nodes, Lao Wang and Xiao Wang. These blocks are connected to form a blockchain.
Fundamentally, blockchain is a distributed ledger database.
What does distributed ledger mean?
Let’s take a look at the traditional accounting method.
The traditional accounting method is a centralized accounting method. For example, if Lao Wang lent 10,000 yuan to Xiao Wang, if Lao Wang did not tell the world about this money, then this amount would Only Lao Wang knows about the money transactions, Xiao Wang knows, God knows, and Earth knows. This accounting method is a centralized accounting method. This method has a very fatal shortcoming: what should I do if the other party does not acknowledge the account? In fact, in real life, in spontaneous private lending relationships, there is no evidence when the lending relationship occurs, resulting in many cases where the other party does not acknowledge the debt afterwards.
The accounting method adopted by Lao Wang from the beginning has prevented future troubles. This method is the blockchain distributed ledger, which has the characteristics of decentralization and allows everyone to It is the center and everyone can testify to the existence of this deal.
In addition to the characteristics of decentralization, blockchain also has the characteristics of being immutable. In the blockchain, if the data in any one block changes, even if it only changes a punctuation mark, it will become invalid and needs to be recalculated. Therefore, in the blockchain technology, once a piece of data changes, the cost will be Very big. Unless all nodes in this blockchain account forHas 51% control. Therefore, the blockchain system will be stable and secure.
It’s still Lao Wang and Xiao Wang. If Xiao Wang wants to default on his debt, he can’t tamper with it unless he bribes everyone in the world who knows about the transaction.
Blockchain is also open and transparent.
In blockchain technology, all data is public, which is still the case of Lao Wang and Xiao Wang.
If Xiao Wang does not acknowledge the money, once this news is released, then Xiao Wang’s reputation will be ruined. He can only release new news and wash away the money by paying back the money. Clear your own identity.
Some people say that if the blockchain is so powerful, will my identity information be revealed and there will be no privacy? In fact, the blockchain has the characteristics of anonymity and protects our privacy very well. Unless required by legal regulations, technically speaking, the identity of each block node does not need to be disclosed or verified and can be done anonymously.
What are the applications of blockchain?
The origin of blockchain is to solve the problem of trust, and one of the most successful applications of blockchain is digital currency. Bitcoin is arguably the most successful application of blockchain so far.
In addition to digital currency, the future applications of Bitcoin are still very wide, and blockchain technology has been widely used in different industries. Such as product traceability, copyright protection and transactions, payment and settlement, Internet of Things, digital marketing, medical care, etc., promoting different industries to quickly enter the "blockchain+" era.
1. Payment and clearing
The role of the intermediary bank can be abandoned, point-to-point payment can be realized, intermediary fees can be reduced, and fund utilization can be accelerated.
2. Product traceability
For example, if we buy a piece of clothing on a certain website, we can see the past and present life of this piece of clothing.
3. Securities trading
Traditional securities trading requires the coordination of four major institutions, which is inefficient and costly. Blockchain technology can independently complete one-stop services.
4. Supply chain
Introduce blockchain technology into the supply chain system, synchronize information within the system, control all links, and better complete division of labor and collaboration. , to facilitate accountability afterwards.
5. Intellectual property rights
With copyright on the chain, our photographic works, musical works, literary works, etc. will become our information, and the ownership of the information will be confirmed and become our property.
⑷ In addition to issuing coins, what are the application scenarios of currency-free blockchain?
The actual application scenarios of blockchain now include:
1. Pain points of traditional information sharing
Either the information is published and distributed by a centralized center, or regular batch reconciliation between each other is required (typically once a day). For information sharing that requires timeliness, it is difficult to achieve real-time shared.
The two parties sharing information lack a mutually trusting communication method, and it is difficult to determine whether the information received was sent by the other party.
2. Blockchain information sharing
First of all, the blockchain itself needs to maintain the data consistency of each node, and it can be said to have its own information sharing function; secondly, real-time The problem can be realized through the P2P technology of blockchain; finally, using the immutability and consensus mechanism of blockchain, a safe and reliable information sharing channel can be constructed.
Okay. You may have this question: To solve the above problem, I can build an encrypted channel myself without using blockchain technology! But I want to say that since blockchain technology can solve these problems and it is very convenient to add nodes, why not use blockchain technology before you have built a safe and reliable information sharing system?
3. Application cases
Let’s take Tencent’s own application—Public Welfare Person Searching Chain—to illustrate the value of blockchain in information sharing. Bitcoin solves the problem of trust in currency issuance and accounting. Let’s take a look at how Bitcoin solves the above two problems one by one.
The problem of spam issuance: Bitcoins can only be obtained through mining, and the total number of Bitcoins available is 21 million. The problem of currency spam issuance is solved in the issuance process; The issue of ledger modification: Bitcoin Coin transaction records form a network through chain storage and decentralized global node balances to solve the problem of ledger modification.
Chain storage can be simply understood as: the blocks that store records are connected one to another, forming a chain; the records of all blocks except the first block contain the calibration of the previous block. Verification information, changing the information of any block will cause subsequent block verification errors. Because of this correlation, other blocks cannot be inserted in the middle, so it is difficult to modify existing records.
⑸ What are the practical applications of blockchain technology
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 to prove that text, video, audioThe existence of videos and other works ensures the authenticity and uniqueness of ownership.
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.
⑹ What are the main application areas of blockchain?
The main application areas of blockchain include: digital currency, transaction settlement of financial assets, digital government affairs, supply chain fields, Automobile industry, public service field, information security field, certificate storage and anti-counterfeiting data certification service and other fields. Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. It is an important concept of Bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each data block contains The information of a batch of Bitcoin network transactions is used to verify the validity of its information (anti-counterfeiting) and generate the next block.
⑺ In addition to issuing coins, what are the application scenarios of currency-free blockchain?
The main application scenarios are (foreign media):
1 , Banking industry
Essentially, a bank is a secure storage warehouse and value exchange center, and blockchain can achieve the same effect as a digital, secure and tamper-proof general ledger. .
2. Payment and cash transactions
The World Economic Forum claims that decentralized payment technology, similar to Bitcoin, can change the "business architecture" due to the cash transaction model. The current architecture has already It has been in existence for more than 100 years.
3. The network is complete
Although the blockchain's account books are public, data communication can be verified and transmitted using advanced cryptography technology. This ensures that the data comes from the correct source and that nothing can be intercepted in the process. If blockchain technology is more widely adopted, the probability of hacking will decrease, as blockchain is considered to be more robust and reliable than many traditional systems. It reduces traditional network security risks
4. Academic records and academia
5. Elections
Elections require voter identity authentication , secure record keeping to track votes, and trustworthy counters to determine the winner. Blockchain can serve the voting process, vote tracking and counting votes so that there is no voter fraud, loss of records or unfair practices.
6. Car rental and sales
Last year it was announced that the partnership would use blockchain to build a proof of concept to streamline the car rental process and build it into a “click, sign up, andThe process of "driving to touch the source". A future customer selects the car they want to lease and enters it into the blockchain's public ledger; then, sitting in the driver's seat, the customer signs the rental agreement and insurance policy, and the blockchain is updated simultaneously Information. This is not a fantasy, this type of process may also develop into reality for car sales and car registration.
7. Networks and Internet of Things
IBM and Samsung has been working on a concept it calls ADEPT, which uses blockchain technology to form the backbone of a decentralized network of IoT devices. According to the CoinDesk website, ADEPT, as anonymous, decentralized peer-to-peer remote sensing technology, blockchain can Becoming a kind of public ledger for a large number of devices, they will no longer need to have a centralized route to mediate traffic between them.
8. Forecasting
Entire Research, Analysis, Consulting The prediction industry is set to be rocked by blockchain. Online crowdfunding platform Augur wants to invest in decentralized prediction markets. The company claims it will provide a service that will be like a regular gambling exchange. The whole process It will be decentralized and will provide a place for users to bet not only on sports and stocks, but also on other things such as elections and natural disasters.” The idea would go beyond sports lotteries to create a “prediction market.”
9. Online Music
In order to make online music more equitable sharing, many music artists turn to blockchain technology. According to Biilbord, the three companies are preparing to establish a more direct payment channel for artists to solve payment problems and solve authentication problems through automated smart contracts. The PeerTracks system is still under development and aims to provide a music streaming platform that allows users to listen to music online and use blockchain technology to pay artists directly without an intermediary
10. Ride sharing
Ride-hailing apps like Uber seem to be the opposite of decentralization, with a company acting as a dispatch center and using its algorithms to control the fleet drivers they are responsible for.
11. Stock Trading
For many years, many companies have worked to make the process of buying, selling, and trading stocks easier. Emerging blockchain startups believe that blockchain technology can make this process more secure, automated, and more efficient than any previous solution.
12. Real Estate
Pain points in the process of buying and selling property are: lack of transparency during and after the transaction, reams of paperwork, potential for fraud, errors in public records Wait, and these are only part of it. Blockchain provides a way to achieve the need for paperless and fast transactions.
13. Insurance
Companies such as AirBnB, Tujia, and Wim provide a way for people to temporarily exchange assets—including private homes—to generate value. The problem is that it is almost impossible for people toThese platforms insure their assets. Along with blockchain startup Stratumn, professional services firm Deloitte and payment services provider Lemonway have just recently released a blockchain-based solution dubbed "LenderBot."
14. Healthcare
Medical institutions have always suffered from the inability to securely share data on various platforms. Better data collaboration among data providers means more accurate diagnoses, more effective treatments, and improved health systems’ overall ability to deliver cost-effective care. Blockchain technology allows hospitals, patients and parties in the medical benefit chain to share data in the blockchain network without worrying about the security and integrity of the data.
15. Supply Chain Management
One of the most widely applicable aspects of blockchain technology is that it makes transactions more secure and supervision more transparent. Simply put, the supply chain is a series of transaction nodes that connect the entire process of products from the supply end to the sales end or terminal. From production to sales, products go through multiple links in the supply chain. With blockchain technology, transactions will be recorded permanently and decentrally, which reduces time delays, costs and manual errors.
16. Cloud storage
Currently, most companies that provide cloud storage place customer data in centralized databases, which increases the danger of hackers stealing information. Blockchain cloud storage solutions allow decentralized storage. Stori is testing the beta version of its cloud storage network product, aiming to improve data security and reduce the transaction costs of storing information in the cloud
17. Energy management
Energy management is another An industry that has long been highly centralized. In the US, if you want to trade energy, you have to go through a trusted energy holding company, such as DukeEnergy, or in the UK, National Grid, or trade with a reseller who has already purchased from the big power companies< /p>
18. Sports Management
Investing in athletes has gradually become a focus of sports management agencies and companies, but blockchain has the ability to democratize fans to gain access to current sports stars. Financial shares in the future can decentralize the process of investing in athletes. This concept of using blockchain to invest in athletes and obtain benefits has not been tried on a large scale.
19. Gift cards and membership programs
Blockchain can help retailers that provide gift cards and membership programs make their systems cheaper and more secure. There is almost no need for any middleman to handle sales transactions and gift card issuance. The acquisition and use process of gift cards using blockchain technology will be more efficient and cheaper
20. Government and public welfare
< p>The distribution of welfare assistance is another area where blockchain technology can be applied. Blockchain can help make public management simpler and safer. GovCoinSystemsLimited is a company headquartered inA London-based fintech company that is supporting the UK government’s work in the welfare distribution space.
