It will open up the traditional centralized information island, realize the business and data sharing under the premise of information security and confidentiality, and avoid the serious economic loss caused by the non-sharing and non-trust of data. It makes use of the trading information of blockchain ledger to realize the tracing industry chain of pharmaceuticals. During the circulation process of medical drugs supply chain, in the m+plus project system, the important information of each link of the supply chain will be confirmed by signature and recorded in the chain after the identification of the third-party information. It includes the procedures of drug production, component manufacturing, pharmaceutical principles, warehousing acceptance, storage, drug maintenance, stock picking, drug review and batch number adjustment. It is the nuts and bolts of medicine circulation in the market. All data are safe and reliable and cannot be tampered with.
