Abstract: A resource distribution method and apparatus. The method is applied to a first server side, including: in response to a resource acquisition request initiated by a first consumer terminal for a target resource, obtaining, from a blockchain network, pre-acquisition information corresponding to the resource acquisition request; when the obtained pre-acquisition information indicates that there is a resource pre-acquisition transaction corresponding to the first consumer terminal and the target resource stored in a blockchain ledger of the blockchain network, returning the target resource to the first consumer terminal. This method can achieve reliable certification of resource distribution records by executing transactions. Based on transactions stored in the blockchain, the distribution process of target resources can be traced, thereby improving the control of target resources and reducing the security risks and infringement hazards of the resource distribution process to a certain extent.
