US Patent 10922757 Blockchain-based commodity claim method and apparatus, and electronic device

Appearance data associated with a target commodity is collected by a blockchain node device, where original appearance data associated with the target commodity is registered with a distributed database associated with a blockchain in advance. Whether a damage event occurs on the target commodity is determined by the blockchain node device based on the appearance data and the original appearance data. In response to a determination that the damage event occurs on the target commodity, a smart contract corresponding to the target commodity is invoked by the blockchain node device. Commodity damage claim logic stated in the smart contract is executed by the blockchain node device to complete a commodity damage claim for the target commodity.
