Embodiment 1
[0043] Example 1. A storage method of an IoT data storage system based on blockchain, such as image 3 with 5 shown, including the following steps:
[0044] (1) The IoT data collection platform packages the log files and data of the platform; the middleware server cluster provides message services to realize the interaction between the IoT data collection platform and the middleware server cluster;
[0045] (2) The middleware server cluster communicates with the IoT data collection platform through the MQ server, processes the business in the IoT data collection platform, generates a data storage service message, and transmits the data storage service message to the block after passing the message on the chain A corresponding block chain server in the chain server cluster; and store log files and data in the file system server and database server respectively;
[0046] (3) The blockchain server in step (2) receives the data from the IoT data collection platform in step (1) ac...

The invention discloses a storage method and system of an IoT data storage system based on a block chain. The system comprises an IoT data acquisition platform which packages log files and data of the platform; a middleware server cluster provides a message service to realize interaction between the IoT data acquisition platform and the middleware server cluster; a block chain server is used for receiving the data of the IoT data acquisition platform according to the received data storage service message sent from the middleware server cluster and carrying out encryption, timestamp generation and data writing operations on the data to form block chain data; block chain data query: checking the identity of the sender to be legal according to the signature, enabling the block chain server to send a data storage request through a distributed peer-to-peer network (P2P network), requesting other block chain servers in the block chain server cluster to carry out data storage accounting, storing block chain data in a block chain account book, and writing successful information into whole network broadcast data.
Description
technical field [0001] The invention relates to the field of food safety monitoring data storage, in particular to a storage method and system of a blockchain-based IoT data storage system. Background technique [0002] Food quality and safety monitoring is carried out based on various food safety-related data, and the integrity, accuracy, and safety of data all affect food quality and safety monitoring. With the maturity of big data technology, the application of big data in food quality and safety is gradually increasing; networked devices, more and more personalized APPs for users, and the growing demand for data sharing all put forward higher requirements for data storage. The increase of data related to food quality and safety has also brought many negative effects, such as increased data operation and maintenance costs, increased processing costs, and reduced data security, affecting food safety monitoring. Contents of the invention [0003] The object of the presen...
