    摘要： A consensus method and a data verification method, apparatus, and system of a consortium blockchain are provided in embodiments of the present specification. The consensus method includes: when a target consensus node of a consortium blockchain performs a consensus operation on a target consensus proposal, sending a verification signature to another consensus node of the consortium blockchain, wherein the verification signature is used to represent at least one consensus verification item set by the consensus node sending the verification signature itself for the target consensus proposal. The target consensus node receives a verification signature sent by another consensus node for the target consensus proposal. After the target consensus node reaches a consensus on proposal data of the target consensus, a block recording a collected verification signature corresponding to the target consensus and the proposal data is generated. The data verification method includes: extracting, from a target block of a target consensus node of the consortium blockchain, recorded proposal data and a verification signature from at least one consensus node. Based on a quantity of extracted verification signatures, the validity of the proposal data recorded in the target block is verified.

    摘要： Embodiments of this specification disclose an offline transaction processing method, apparatus, and device. The method is applied to a first terminal of a transaction initiator. The method includes the following: Information about a current network connection status of the first terminal is obtained for a target transaction; if the current network connection status of the first terminal is connected, and it is determined that a network connection status of a second terminal of a transaction target party of the target transaction is unconnected, or the current network connection status of the first terminal is unconnected, it is determined whether the first terminal can output a transaction identification code used to trigger offline transaction processing on the target transaction; and an offline transaction policy corresponding to a determining result is selected based on the determining result indicating whether the first terminal can output the transaction identification code, and offline transaction processing is performed on the target transaction between the second terminal based on the selected offline transaction policy.
