## Abstract

The present specification discloses a method for generating a target contract and a terminal device. The method includes: generating, based on an operation instruction of a first user, a contract signing request to sign a contract with a second user cluster; sending the contract signing request to a second terminal device cluster corresponding to the second user cluster, for M second terminal devices in the second terminal device cluster to each generate and return, based on the joint contract signing request, a piece of first acknowledgment information that acknowledges jointly signing a contract; determining, based on M pieces of first acknowledgment information, chat information from group chat records in a same chat group as the second user cluster; generating a pending contract based on the chat information, and sending the pending contract to the second terminal device cluster, for P second terminal devices in the second terminal device cluster to each generate a piece of second acknowledgment information that acknowledges the pending contract; and determining the pending contract as a target contract based on P pieces of second acknowledgment information, and uploading the target contract to a blockchain.
