Logistics document archiving method and system based on block chain and interstellar file system

Abstract

The invention discloses a logistics document archiving method and system based on a block chain and an interstellar file system, and relates to the technical field of block chains. The method comprises the steps of recording a logistics document circulation process and a logistics document state through a logistics platform management system; constructing an interstellar file system IPFS for storing logistics documents; determining an interface standard of an IPFS and a logistics platform management system; signing a logistics receipt through an API interface and archiving the logistics receipt to an IPFS after a logistics document is finally confirmed through the logistics platform management system; andrandomly storingthe interstellar file system IPFS the plurality of small file blocks in an IPFS node and correspondingly generating a unique hash table. Through encryption and timestamp characteristics based on a block chain technology, tamper resistance and credibility of logistics document transmission and final archiving can be ensured; the IPFS interstellar file system is based on hash encryption, P2P protocols and other technologies, can guarantee the permanence of logistics document archiving, guarantees low storage cost, and is more effective in retrieval.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a logistics document archiving method and system based on block chains and an interstellar file system. Background technique [0002] When a logistics company has a business relationship with a cargo owner, a logistics order will be generated, and the life cycle of a logistics order is extremely long; logistics orders can be divided into pre-order, order generation, pending order, received order, and execution (picked up, in transit, in transit) according to status. Abnormal, arrival and signing), receipt (the receipt certificate is returned to the owner), and order receipt is archived and stored. It is very important to update the status of logistics orders in real time and ensure that they are archived in a trusted location, which is related to the service quality of logistics companies and whether the clearing and settlement can be carried out smoothly; existi...

Problems solved by technology

[0004] (1) Circulation and storage of paper logistics documents: According to a single logistics company, there are about 500 documents per day, 360 days a year, and there are 180,000 documents a year, and they must be kept for at least three years. The cost of certificate circulation management and logistics storage space is huge;

[0005] (2) Logistics documents in the SAAS system: According to a document of 100KB, a logistics company has 500 documents per day, 360 days a year, then 100*500 / 1000*500*360=18000M=18G documents ;A logistics platform has about 1,000 customers, and there are 18T a year; this is a huge investment in information systems and hardware; at the same time, the simplification of storage software (logistics platform, a certain logistics company, and a certain cargo owner) also brings The issue of the credibility of evidence deposits, when a dispute occurs, the credibility and efficiency of evidence collection is not high;

[0006] (3) At the same time, it is difficult to retrieve such paper and electronic logistics documents, which will also waste a lot of manpower and financial resources

[0007] (4) The risk of physical loss and loss of documents is high: when natural disasters such as fire, flood, and mudslides occur, or the information system storing logistics documents collapses, and the website and database are closed, the logistics documents will also be lost. The logistics company and the owner of the goods that guarantee the preservation of the demand will bring losses;

[0008] In short, logistics documents rely on the information system of the logistics company or the logistics platform, and there are many problems in the transmission process, such as long time, no real-time witness, low reliability, high storage cost, loss of document data, etc.
