Household appliance data storage method and device based on block chain

The embodiment of the invention provides a household appliance data storage method and device based on a block chain. The method comprises the steps that a storage node receives a service data storagerequest from user equipment, wherein the service data storage request comprises to-be-stored household appliance data; the storage node stores the household electrical appliance data to be stored, and sends a storage certificate to the user equipment after the storage is completed; the storage node sends the storage proof to the block output node; and the block output node records the storage proof in a block chain, so that the user equipment confirms the authenticity of storage of the to-be-stored household appliance data through the block chain after a preset time. Therefore, the real-timestorage of the service data is realized, the storage delay of the data is reduced, and the user experience is improved. 本发明实施例提供了一种基于区块链的家用电器数据存储方法及装置。该方法包括：存储节点接收来自用户设备的业务数据存储请求，所述业务数据存储请求包括待存储的家用电器数据；存储节点对所述待存储的家用电器数据进行存储，并在
