Problems solved by technology
However, at present, the donation process of public welfare relief items on the public welfare relief item donation platform is not transparent enough, and there are often many problems. The process cannot be tracked; and the recipient "cheats" or discards the donated materials at will, cannot make full use of the donated items, and wastes the love of the donor, etc.
It can be seen that the opacity of the public welfare donation platform has greatly affected the credibility of the public welfare platform, which in turn has also affected the public's public welfare awareness and social public welfare atmosphere

Abstract
The invention discloses a public welfare donation article tracking method and device based on a block chain and the Internet of Things, and aims at carrying out public transparent management on publicwelfare donation articles so as to reduce fraud problems and improve the authenticity and social public trust of public welfare donation. The method comprises the following steps: firstly, receivinga public welfare donation article information uplink request sent by a bank public welfare rescue platform; writing the public welfare donation article information into a block chain; then, receivinga first sensor information uplink request and a first logistics information uplink request sent by an article manufacturer, then, receiving a second logistics information uplink request sent by the logistics company, and receiving a second sensor information uplink request sent by the sensor, and tracking the public welfare donation article according to the first sensor information uplink request,the first logistics information uplink request, the second logistics information uplink request and the second sensor information uplink request to obtain a tracking result.
Description
technical field [0001] This application relates to the technical field of blockchain, in particular to a method and device for tracking public welfare donations based on blockchain and the Internet of Things. Background technique [0002] Blockchain is essentially a distributed, multi-centralized chained data storage system, which has the characteristics of decentralization, programmable time series data, and security and credibility. With the help of the powerful computing power formed by the consensus algorithm such as the workload proof of each node in the distributed system, it can resist external attacks, ensure that the blockchain data cannot be tampered with, and ensure that the data is safe and reliable. [0003] The core concept of the Internet of Things is to convert the implicit data of the physical world into explicit data through sensing devices such as sensors, and then obtain the operating laws and related knowledge of the objective world from the explicit dat...
