Methods, systems, and apparatus, including computer programs encoded on computer storage media, for tracing capital chain information are provided. One of the methods, implemented by a computing device, includes: receiving a query request for querying capital chain information of a target account; parsing the query request to obtain an account identifier of the target account and a query condition; retrieving, based on the account identifier from a blockchain system, a plurality of pieces of capital change information of the target account meeting the query condition, wherein the plurality of pieces of capital change information of the target account are pre-recorded in the blockchain system based on a consensus mechanism; and obtaining the capital chain information by linking the plurality of pieces of capital change information based on information associated with a timeline or a plurality of participants associated with the pieces of capital change information.
