Logistics data sharing method and system based on block chain

The invention discloses a logistics data sharing method and system based on a block chain, and belongs to the technical field of logistics data sharing. According to the invention, logistics waybill data among different logistics platforms are communicated, information intercommunication between upstream and downstream enterprises of logistics is facilitated, data right confirmation is realized through access control, each time of utilization of data is guaranteed to have a record which can be found through behavior records, and the logistics platforms maintain a list library capable of providing services together. When financial institutions, superior departments and the like have query service requests, original data are called through the block chain according to waybills needing to be queried, after the original data are calculated at the edges of all logistics platform systems, results are input into the sandbox safety bin to be calculated again, and finally query results are fed back, so that data leaka
