Supply chain is a chain of the block field of application, having a relatively high early development and maturity. In recent years, the block chain as a new application model in different industries has been widely used. Including financial, networking, social welfare, supply chain and other areas, there are many applications to explore and try. Among them, the market supply chain for its large-scale, multi-trust body, and more collaboration to become high-profile block chain technology.
Limitations of the traditional supply chain,
the supply chain can be regarded as suppliers, manufacturers, warehouses, distribution centers and channel partner network. The core supply chain concept is to establish trust and cooperation between the bodies, before the formation of a loose chain enterprise, integrating discrete chain information gathering. With the continuous expansion of the scope of the supply chain, companies to coordinate their own and external resources through effective supply chain management, to meet market demand. In the supply chain, the interaction between capital flows, and the actual information flow stream extremely difficult to reconcile. The traditional owners of single-chain coordination core business model has been unable to meet the diverse needs of the market, rapid development.
In this mode, the core business is to survive as though everyone in the entire chain of supply chain management system, but because of its limited control of the supply chain upstream and downstream, and opaque asymmetric information problems, and even false information the risk of tampering. On the one hand, these problems will make it difficult to core enterprise supply chain management extends to the upstream and downstream. On the other hand, it will be difficult to ensure reasonable integration of core enterprise supply chain logistics, information flow and financial flows, resulting in asymmetric management capacities and needs. With the development of supply chain management technology, it appeared on the market a series of supply chain to help improve the level of collaboration tools, such as vmi vendor managed inventory, jit immediate delivery, supply chain financing 1n model. However, these tools are always dependent on the core business unified planning and coordination, direct communication and cooperation between the upstream and downstream businesses rather than remain difficult to effectively solve the problem.
Block chain technology supply chain
trust provides cooperation mechanisms block chain provides a reliable technical support to address multiple issues such as cooperation in the supply chain. According to the technical characteristics of the supply chain, we analyze the innovation chain to supply chain brings.
1, to prevent the supply chain data storage
More emphasis on supply chain data stored search of depth and can ensure that the required records can be traced back to the last transaction layer. At its core is created for each product according to a source other components. Block chain technique unique data storage method such that information related to raw materials supply chain, assembly production information, supply chain information for each data in each transport of goods and finished permanently stored in the form of blocks. According to all types of recorded information between enterprises on the supply chain, easily traced back to the source of the data, but also help solve the problem of fake and shoddy products. Meet each of the supply chain by this participant data storage block chain framework needs to: enter and track sources of raw materials; recorded telemetry data production means; track down the source of shipping goods.
2, to prevent tampering with the data in the traditional supply chain
data mostly from the core business or participate in a business way scattered and isolated centrally stored. When the information on the books against themselves, there is the risk of account information has been tampered with or deleted by privately. Unfalsification nature and the time stamp data packet train technique to ensure that all data, including the production of finished products, storage, transportation, sale and tracking, is not tampered with. Data is not tampered with, the information asymmetry is greatly reduced, reducing the cost of Credit Reporting and communication between enterprises. This application will help companies quickly build trust, while sharing risks borne by the core business. Block chain technique ensures lossless data flow between the upstream and downstream supply chain, and to avoid distortion and distortion information.
Domestic and international supply chain application status
of supply chain applications in the field block chain technology enables manufacturers and distributors to more effectively monitor the flow of goods, and fully mobilize the resources on the supply chain. For consumers, they have a more intuitive, more reliable understanding of the ins and outs of commodities.
Can effectively solve the transport stream based on the field of logistics platform block chain line art data and information opaque dispersion problems. Users can monitor the target object through Internet-connected devices, and in a transparent manner to track the source of the transaction process and intermediate goods. On the block chain, you can not only view the static property information products, it can also monitor the process of product from manufacturers to distributors to end consumers transit transport, tracking the entire product lifecycle, and improve the overall efficiency of the industry. In recent years, many domestic and foreign enterprises to actively explore the application of the block chain in the areas of traceability, logistics, supply chain, finance and the like.
Block chain technology is gradually penetrate into the traditional supply chain services. For example, Maersk joint insurance agencies, block chains and other parties jointly established the world's first marine insurance block chain platform, cross-industry alliance formed a chain; Wal-Mart, the world's largest retailer, has been completed in China block chain technology to track the use of pork production and sale of the whole trial process, greatly reducing the track time.
