『Lu』 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 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 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: 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 and public welfareThe organization provides implementation of public welfare activities, and poverty alleviation merchants provide sales of public welfare and poverty alleviation commodities.

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.

『撒』 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 e-commerce in counterfeiting To solve the pain points in cargo, 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. Currently three-quarters of transactions in China’s e-commerce marketIt is completed on the mobile side. Payment trust is a major problem that the platform needs to solve, and blockchain is called a "trust machine". To give you an example, many online stores will fake orders or falsify data in order to get good reviews. phenomenon, and the purchase information cannot be tampered with after it is uploaded to the chain, ensuring 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.

『8』What are the application cases of blockchain?

Currently, companies in medical, government, transportation, technology, manufacturing, entertainment, games and other fields are already using blockchain technology. . As shown in the figure below, blockchain has proven to be very useful in various fields. Currently, listed companies using blockchain include Facebook, Alibaba Group, Microsoft, Siemens, Ford Motor Company, etc.

『玖』 What are the practical application cases of blockchain in China

The most widely used application of blockchain is still in the field of financial technology, such as Digital asset trading. As an underlying technology, blockchain is the technical implementation method of Bitcoin. The rapid application of blockchain technology also requires virtual currency. In the past, a large-scale economic scenario that required mutual trust and extensive collaboration among many people could only be solved through a centralized approach, which was very inefficient. The emergence of blockchain technology solved this problem and eliminated this center. An important reason why this center can be removed is that virtual currency provides an endogenous economic incentive mechanism for the blockchain, allowingPeople are motivated to participate in economic activities transformed by blockchain. Of course, blockchain will have more extensive and mature applications in more fields in the future. For example, in November last year, the State Grid submitted a patent application titled "About blockchain power transaction control methods and devices." This year, Xi'an The City Wall International Marathon is also the first in the world to use blockchain technology to register athletes' race data, winning links and other information on the blockchain, using its traceable and non-tamperable technical features to open up information channels between events and effectively Guaranteed the reliability of competition results.

『Shi』Examples of other practical applications of blockchain

Starting from November 8, the Walmart Jinhai Road branch in Baoan, Shenzhen will provide users with blockchain electronic invoices For issuance services, the electronic invoices issued will be directly entered into the consumer's WeChat card wallet. This is the first time that electronic invoices have been applied to large chain retailers.

In fact, on August 10 this year, Shenzhen’s Guomao Revolving Restaurant issued the country’s first blockchain electronic invoice. So, what are the characteristics of blockchain electronic invoices that make Shenzhen, a pioneer city in the country, willing to use it as an important "Internet + Taxation" project between the Shenzhen Taxation Bureau and Tencent in the "Smart Tax" Innovation Laboratory this year? What about floor-to-ceiling products?

1. It is more convenient to issue invoices

In the past, when issuing invoices in supermarkets, you had to check out at the cashier and then go to the service desk to queue up and issue invoices based on the shopping receipt. If the user provides wrong information at this time, it will be very troublesome to void the invoice and reopen it. The emergence of blockchain electronic invoices allows enterprises to apply for invoices on the blockchain; users can issue invoices on the chain, and after the transaction is completed, they can apply for invoices by themselves by scanning WeChat on their mobile phones, and invoice collection is electronic. and convenience, achieving "instant invoicing of transactions", making the entire process more convenient and faster.

2. Supervision is more convenient

Since blockchain electronic invoices are issued directly in the system, there are fewer human intervention factors, and for tax regulators and managers, the tax bureau In other words, technological innovation can achieve full-process supervision, realize paperless intelligent tax management, and make the tax process more controllable.

3. Financial information is more authentic and reliable

Due to the addition of the underlying technology of blockchain, the information on electronic invoices cannot be tampered with, which makes internal financial statistics within the enterprise. Various opportunities for fraud are avoided, the financial reimbursement process is optimized, and work efficiency is improved.

It is almost foreseeable that with the participation of global giants such as Wal-Mart, electronic invoices will be used in more fields. In the context of this year's tax reform, technological development will also provide greater support to the tax system of Shenzhen, an international metropolis.
