Quality traceability helps food and drug safety and precision poverty alleviation
According to incomplete statistics, the market scale affected by counterfeit and shoddy goods worldwide is as high as 300 billion US dollars. Among them, food and drug safety incidents occur frequently, and the resulting trust crisis has been highly concerned by the society and solved by technical means. The focus of government and business concerns.
Based on the decentralization, consensus mechanism, non-tamperable, and information traceability of blockchain technology, Jingdong Blockchain Anti-Counterfeiting Traceability Platform has launched consumer product solutions and pharmaceutical industry solutions. As of February this year, the platform has accumulated more than 700 brands and more than 50,000 SKUs. The brand names include Nestlé, Wyeth, Yanghe, Yili and other well-known enterprises. The platform has more than 2.8 million after-sales users access, with up to 1.3 billion on-line data. The product range includes food, alcohol, milk powder, daily necessities and medical supplies, contributing to a safe and reliable consumer experience and medical services.
For example, Angus, Australia's leading exporter of meat products, has deep cooperation with the Jingdong blockchain anti-counterfeiting platform to enable domestic consumers to understand the birth, growth, quarantine, and cattle from the cattle by scanning the QR code on the package. All the information such as slaughtering, processing and transportation will be automatically recorded in every link during the period. Every link can not be artificially altered, and every link can be publicized to consumers, so that every piece of beef is safe and reliable.
At the same time, the anti-counterfeiting traceability technology of the blockchain in Jingdong District is also applied in the field of precision poverty alleviation. Jingdong’s “running chicken”, “youshui duck” and “flying pigeon” projects in the national poverty-stricken counties passed the footsteps. IoT equipment, combined with video traceability technology, collects poultry sports data, feeding, drinking water, de-worming and other information, and records it in the blockchain network. Consumers can understand the breeding process of purchased agricultural products. Graphic information such as the growing environment, while improving the consumer experience, has also increased income for farmers in poor areas.
Digital deposit certificate and credit network service integrity system construction
In terms of digital deposit certificate, the blockchain digital deposit certificate platform of Jingdong District has realized functions such as trusted deposit, automatic forensics, one-click proof, and infringement warning.

Recently, Jingdong Group and Guangzhou Internet Court jointly signed a cooperation agreement between the Trusted Electronic Evidence Platform and the Judicial Credit Co-ruling Platform. The two parties will use their respective professional experience and technical advantages to ensure that the evidence data process is traceable and recordable. Evidence data storage is secure, verification is convenient, and the principles of safety, justice, neutrality, and openness are followed together to properly maintain evidence data. At the same time, the two sides will also share judicial credit information under the premise of laws and regulations and user authorization, and provide effective support for promoting the construction of cyberspace credit system.
In addition, “Jing Xiao Rent” is the first credit leasing platform in the industry that uses blockchain technology to solve the problem of consumer disputes in the consumer leasing market. When the user rents goods, the Beijing small rent platform obtains the leasing business through automated processes. Lease agreement, order data, rental process and other data and complete the "winding" operation to ensure the open and transparent lease service.
In terms of credit network, the irreparable modification and transparency of blockchain technology can serve the construction of social credit system, solve the pain points of the past credit system, and assist the regulatory agencies to achieve credit evaluation of social subjects.
