The invention provides an edge computing node data transmission method, a system, a device and a storage medium. The method comprises the following steps of caching data to be sent to a block chain ina hardware cache by an edge computing node; reading the data from the hardware cache by the edge computing node; generating a data message to be sent to the blockchain endorsement node for identification; sending the data message to each blockchain endorsement node to execute an intelligent contract specified by the corresponding data message; receiving the message reply of each block chain endorsement node and storing the signature of each block chain node to the data message into a hardware cache by the edge computing node; and generating a data message packet according to the signature ofeach node to the data message and the data message, and sending the data message packet to a blockchain entry service for entry. According to the method, the data connection from the Internet-of-thingsInternet-of-things edge computing node to the blockchain is supported, the efficiency of executing blockchain communication can be ensured, and the identity information of the edge computing node canbe ensured to be safely stored on the node.
Description
technical field [0001] The present invention relates to the field of data transmission, in particular, to a method, system, device and storage medium for edge computing node data transmission. Background technique [0002] At present, there are a large number of nodes with edge computing capabilities in the Internet of Things. The data generated by existing edge computing nodes has the risk of easy tampering and data leakage, which creates a huge demand for IoT data to be connected to the blockchain. Moreover, the hardware of most current edge computing nodes cannot meet the huge encryption and decryption overhead introduced by directly communicating with the blockchain. At the same time, running the blockchain client software on the edge computing node hardware consumes a lot of computing resources and cannot be applied to most low-energy computing edge nodes. Contents of the invention [0003] In view of the problems in the prior art, the purpose of the present inventi...
