Methods, systems, and devices, including computer programs encoded on computer storage media, for payment are provided. One of the methods includes: sending a consensus proposal for at least one pending-consensus transaction in a transaction pool of the consensus master node to a target consensus backup node of the blockchain, wherein the consensus proposal comprises a transaction hash list, and the transaction hash list comprises a transaction hash of the at least one pending-consensus transaction; matching the transaction hash in the consensus proposal with transactions in a transaction pool of the target consensus backup node; in response to the transaction hash being matched, obtaining, from the transaction pool of the target consensus backup node, transaction information of the matched at least one pending-consensus transaction; and executing a process of the consensus proposal based on the transaction information. |
