Embodiment 1

[0051] This implementation proposes a blockchain-based data storage method for the Internet of Things, including: the Internet of Things includes at least two master nodes that are communicatively connected to each other, and each of the master nodes manages a plurality of nodes that are communicatively connected to it equipment.

[0052] It should be noted that the master node can be set as a background server. As a master node, the background server can store and monitor the device status of each node device, and can also send instructions to each node device, and each node device completes a specific Moreover, the information interaction between each node device also depends on the background server for data transmission. The node device may be various Internet of Things devices, and multiple Internet of Things devices and background servers form an Internet of Things system. Specifically, the IoT device may be a smart home device. It can be understood that the Internet o...

Embodiment 2

[0079] This embodiment is based on the first embodiment, please refer to image 3 , a block chain-based Internet of Things data storage method of this embodiment includes:

[0080] S210. Any one of the master nodes collects data of multiple node devices managed by it;

[0081] S220. The master node classifies the data of multiple node devices according to the preset data volume threshold to obtain the first type of data with a large data volume and the second type of data with a small data volume, and classifies the first type of data compressing the first type of data so that the data volume of the first type of data is less than or equal to the preset data volume threshold;

[0082]Due to the existence of massive heterogeneous data (that is, data of different data structures) in the Internet of Things, the aforementioned multimedia data includes image data, audio data, video data, and the like. The data size of these different IoT data is often very different. In order to ...

Abstract

The invention discloses an Interne-of-Things data storage method based on a blockchain and an Interne-of-Things system. The Internet of Things at least comprises two main nodes in communication connection with each other, and each main node manages a plurality of sets of node equipment in communication connection with the main nodes. The Interne-of-Things data storage method based on the blockchain comprises the steps of: collecting data, by means of an arbitrary main node, of the plurality of sets of node equipment managed by the main node; performing unified data expression operation on thedata of the plurality of sets of node equipment to obtain a plurality of pieces of to-be-stored data; and based on a preset consensus algorithm, synchronizing the plurality of pieces of to-be-stored data to each main node and node equipment. According to the Internet-of-Things data storage method based on the blockchain and the Internet-of-Things system of the invention, the blockchain is adoptedto realize sharing and synchronization of the Interne-of-Things equipment data. Due to the fact that the blockchain has tamper resistance, the Interne-of-Things data written into the blockchain cannotbe maliciously forged or modified, and distributed storage, tamper resistance or loss of the Interne-of-Things data are achieved.

Description

technical field [0001] The present application relates to the technical field of the Internet of Things, and in particular to a blockchain-based data storage method for the Internet of Things and an Internet of Things system. Background technique [0002] In recent years, the popularization and rapid development of IoT technology have made IoT applications ubiquitous in daily life and play an important role in various fields. However, due to its openness, the existing Internet of Things system has always had the problem of data being illegally tampered with or easily lost due to interaction, which affects the practicability of the Internet of Things. Contents of the invention [0003] The embodiment of the present application aims to solve the problem that the source data in the data storage in the Internet of Things system is easily tampered with or lost by providing a blockchain-based IoT data storage method and an IoT system. [0004] This application proposes a blockc...
