However, since the data uploaded in the blockchain cannot be changed, when the original monitoring data is uploaded, the integrity of the original monitoring data needs to be checked to generate a check result. It should be noted that, when receiving the original monitoring data, the receiving device may malfunction, for example: if the original monitoring data is not received at a certain moment or the receiving device sends a short fault, which causes that the data of the original monitoring data is too large or too small, the intelligent contract can judge the integrity of the original monitoring data by judging whether the original monitoring data to be uploaded has blank or is in a value conforming to the theorem, and the original monitoring data conforming to the integrity is uplink in a blockchain.

Wherein the response event may be executed by the recipient device or an additional processing device may be provided in communication with the smart contract, the processing device being configured to execute the response event.
It should be noted that the preset threshold value is also configured in the smart contract, and may correspond to different types of raw monitoring data. Such as: the original monitoring data is air monitoring data, and then the preset threshold value can be a sound decibel value; for another example: the original monitoring data is soil monitoring data, and then the preset threshold value can be a PH value.
In an alternative embodiment, in case the original monitoring data does not meet a preset threshold value, the method further comprises:
