## Abstract

This disclosure relates to blockchain-based copyright distribution. In one aspect, a method includes receiving, by a node device of a blockchain network, a target transaction including design data of a target work and an identity of a target copyright user corresponding to the target work. Design similarity comparison logic and copyright distribution logic are executed. The design data of the target work is compared with the design data of the existing work stored in the first smart contract to obtain a target similarity between the target work and the existing work. A copyright for the target work is distributed between the target copyright user and a copyright user corresponding to the existing work based on the target similarity. Copyright distribution data that specifies distribution of the copyright between the target copyright user and the copyright user corresponding to the existing work is stored in the first smart contract.
