This article introduces the relevant knowledge of "what is the business scenario of blockchain application". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

I. supply chain Finance

Today, the supply chain of most goods, from the provision of raw materials to the manufacture of finished products, will involve several upstream and downstream small and medium-sized enterprises, which are under pressure to unlock the working capital of the supply chain. Supply chain finance means that banks and other financial institutions make systematic financing arrangements for all members of the supply chain, thus forming a win-win situation between the core buyer and the supplier: the buyer optimizes the working capital and the supplier generates additional operating cash flow, thus minimizing the risk of the whole supply chain. There are three pain points in traditional supply chain finance:

1. Information can not be shared, low efficiency and poor credibility

two。 Tickets-inconvenient circulation, slow settlement of contracts, often capital risks; 3. Credit cannot be passed on and financing is difficult.

The blockchain can achieve the following functions:

1. Core enterprises, multi-level suppliers, financial institutions share transaction data, data receivable and payable, and protect business privacy

two。 Enterprise creditor's rights transfer, automatic settlement of funds, accelerate enterprise payback and repayment

3. The payment commitment of the core enterprise transfers between multi-level suppliers and financial institutions to transfer the credit of the core enterprise.

II. Tracing the Source of Commodities

In the field of commodity traceability, Aliyun combines blockchain and Internet of things technology to trace the whole process of commodity circulation, so as to prevent illegal traders from making use of the information asymmetry in the commodity chain to produce fake and shoddy commodities. Prevent some participants from tampering with data or falsely claiming the loss of information when there is a situation against them, resulting in difficulties in providing proof and accountability. In addition, block chain traceability can open up the information islands in different links of the supply chain and improve the cooperation efficiency of the supply chain.

III. Medical services

The blockchain medical solution jointly developed by Aliyun and Alipay has been formally applied to the electronic prescription circulation scene of Wuhan Central Hospital. The solution is based on Aliyun Block chain Service (BaaS) and Alipay's ant block chain technology, and can open up many links such as hospital prescription, pharmacist examination, drug distribution, drug payment, process supervision and so on. Through block chain distributed storage and accurate matching of information on the chain with patients, to ensure the effectiveness of one-time prescription dispensing, put an end to prescription modification or abuse, easy to supervise and so on. In the future, patient information, prescription information and drug circulation information can be encrypted and desensitized by block chain technology, which can open up more medical application scenarios.

IV. Industrial Internet

At the Fifth World Internet Congress, the supET industrial Internet platform, which combines the Internet of things and blockchain technology, was selected as the world's leading scientific and technological achievement of the Internet, and became the only award-winning industrial Internet platform. Among them, Aliyun IoT's blockchain scheme provides three types of scenario applications for supET projects: industrial equipment certification, product quality traceability and supply chain management services. In addition to supET, Aliyun has jointly launched corresponding industrial Internet platforms in Guangdong and Chongqing.

In the industrial Internet of things, the terminal IoT equipment collects all kinds of data, combines edge gateway devices to make real-time decisions, and connects with the cloud, and connects the physical world and the digital world credibly through blockchain technology. This kind of complete general industrial PaaS cloud platform can be used in electronic manufacturing, mechanical manufacturing, textile and clothing and other sub-industries to achieve scene-based applications.

Blocks have a wide range of business applications in industries such as government, finance, industry and logistics, health care, retail and the Internet.
