description The embodiment of the invention relates to the field of big data processing, in particular to a block chain-based mobile phone residual value evaluation method, which comprises the following steps of: periodically and autonomously acquiring component information of each component in a mobile phone by a block chain access client which is built in the mobile phone and is not perceived by a user, and performing hash calculation on the component information to generate a hash value of each component; after the block chain access client generates the hash value of each component each time, the currently generated hash value of each component and the identification code uniquely identifying the mobile phone are associated and stored in the block chain; and in response to an information query operation on the mobile phone, the block chain access client queries the block chain, acquires the hash values of all components stored in association with the identification code of the mobile phone from the block chain, and d
