A. What are the application examples of blockchain?

1. Judicial deposition

On September 18, 2018, the Hangzhou Internet Court officially On the chain, it became the first court in the world to use blockchain for trial.

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

2. Logistics field

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

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

3. Electronic invoices

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

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

There are many practical applications of blockchain, you can learn more about the relevant information.

B. What Alibaba did on the blockchain

Jack Ma: I want to know what Bitcoin can bring to society

At the two sessions, Jack Ma... …Oh, I’m sorry, Comrade Jack Ma, who didn’t want to wear a red hat, did not attend the two sessions.

So, let’s review Jack Ma’s remarks when evaluating Bitcoin:

In November 2017, Alibaba, Ant Financial and Xiongan Signed a strategic cooperation agreement to build the "Digital Xiongan Blockchain Implementation Platform". Currently, Ant Financial has provided blockchain application technology in the rental field in Xiongan. It can be said that Xiongan has become Alibaba’s first experimental field for the overall implementation of blockchain technology.

D. What are the applications and successful examples of blockchain?

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

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

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

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

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

For specific implementation, we take the two domestic e-commerce giants as examples. Alibaba has begun to introduce blockchain since 2016. First, Ant Financial launched blockchain technology to pay for charity donations, which was the first test of blockchain technology; in 2017, Ant Financial’s technology experiment Office announced the opening of blockchain technology to support imported foodProduct 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 the country of origin, country of shipment, and loading of the goods. 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.

E. In what fields has the traceability service of Ant Blockchain been applied?

As far as I know, the application of Ant Chain in traceability started with Tmall International in 2018. On Tmall’s Double 11 this year, Ant blockchain technology traced the origin of 150 million products to ensure authenticity. Now Ant Chain traceability has also played a huge role in epidemic prevention and control. For example, "Zhejiang Cold Chain", a cold chain food traceability system based on Ant Blockchain and Alibaba Cloud, can realize products from the first stop of the supply chain to the consumption link. Closed-loop traceability management of minimal packaging to control the flow of the cold chain food supply chain.

F. Under what circumstances should Tmall International traceability code be posted?

Working error requires Tmall International traceability code
It is recommended to communicate with customer service and ask for the traceability code. If the traceability code cannot be provided, you can return the product and make a complaint.
The "visa" issued by Tmall International for overseas products is actually a traceability code. When overseas merchants purchase goods, they will paste the traceability code on the surface of the goods as required, and enter the purchasing location, purchasing time, purchasing personnel and other information through the back-end system. During the logistics transfer process, the traceability code will also record logistics information throughout the process. After receiving the goods, users can use their mobile phones to scan the traceability code to find the full link information of the goods from abroad to home.
The traceability code is made using a special process. It is destroyed when torn off and cannot be recycled. With the help of blockchain technology, all information recorded by the traceability code will be properly preserved and cannot be modified. The application of dynamic laser technology and dynamic image recognition technology ensures that the traceability code cannot be imitated or copied.
Currently, blockchain traceability technology services have covered Tmall International’s milk powder, health food, nutritional supplements, beauty masks, beauty essences and other product categories that are closely related to consumer health. In the future, it plans to cover 25,000 overseas brands in 5,100 categories from 92 countries and regions around the world.
