[0056] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of the present application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit the present application; the terms "including" and "having" and any variations thereof in the specification and claims of the present application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of the present application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0057] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0058] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] See also Figure 1 ,like Figure 1 As shown, Figure 1 is a schematic diagram of an application environment of an environmental quality data management system / method in an embodiment of the present invention. The environmental quality data management system / method provided by the present application can be applied in Figure 1In the application environment, the blockchain is composed of several nodes that can communicate with each other. Each node can be regarded as a block storage. Each block storage is used to save data. Each data node contains all data. The block storage data has a complete historical record and can be quickly restored and expanded. The regional chain is divided into public chain, private chain and alliance chain. The public chain is open to any node. Every organization / node can participate in the blockchain calculation, and any organization / node can download and obtain complete blockchain data. The private chain is that some blockchains do not want anyone to participate in this system. It is not open to the public and is suitable for internal data management and auditing or open testing of specific institutions. The alliance chain is that the permissions of each node participating are completely equal. Everyone can achieve trusted data exchange without full mutual trust. Each node of the alliance chain usually has a corresponding entity organization. Only after authorization can they join and exit the network. In the process of using the entire blockchain backup system, digital signatures are required. Digital signatures design a hash function, the sender's public key, and the sender's private key. The blockchain has complete distributed storage characteristics. In fact, it is a larger network data storage and uses a data structure in the form of a "hash algorithm" to save basic data.
