Abstract: A second blockchain system receives a first consensus message from a first blockchain system, the first blockchain system includes first nodes that provide services to at least a first account, and the second blockchain system includes second nodes that provide services to at least a second account. The first consensus message indicates a first plurality of the first nodes reaches a consensus for transferring a resource from the first account to the second account. The second blockchain system transfers the resource in the task to the second account. The transferring includes that a node in the second nodes adds the resource to the second account and generates a fourth block that records a completion of a transfer event. A second consensus message is transmitted from the second blockchain system to the first blockchain system in response to a second plurality of the second nodes completing the transfer event.

Abstract: The present disclosure discloses a client device having a digital signature. The client device includes processing circuitry configured to send a message to be stored in nodes after the nodes reach a consensus on the message. The message includes the digital signature of the client device. The processing circuitry obtains results from a subset of the nodes that receive the message. The results have respective digital signatures of the subset of the nodes. The nodes are in a first consensus mode for reaching the consensus on the message. After verifying the digital signatures, the processing circuitry determines whether one or more of the nodes has malfunctioned based on the results. Based on a determination that the one or more of the nodes has malfunctioned, the processing circuitry triggers the nodes to switch from the first consensus mode to a second consensus mode for reaching the consensus on the message.

Abstract: The present disclosure discloses a distributed system and a message processing method. The distributed system includes a client and a plurality of nodes. The client includes processing circuitry that is configured to send a message including a digital signature of the client. The distributed system is in a first consensus mode for reaching a consensus on the message. The processing circuitry obtains results from a subset of the nodes that receive the message. The results have respective digital signatures of the subset of the nodes. After verifying the digital signatures of the subset of the nodes, the processing circuitry of the client determines, based on the results, whether one or more of the nodes in the distributed system is malfunctioned.

Abstract: This application relates to a shared data recovery method performed at a first node of a data sharing system. The first node obtains a first eigenvalue of a first node after receiving a recovery request carrying a first block height; broadcasts the first eigenvalue to at least one second node and recovery indication information to the at least one second node. After determining, based on the first eigenvalue and a plurality of second eigenvalues, that data in shared data stored by all nodes of the data sharing system is consistent, the first node recovers data within a range of the first block height in the shared data after receiving a preset quantity of a plurality of pieces of recovery indication information, thereby ensuring consistency and security of data included in a block, and reducing pressure on a node of the data sharing system to store the shared data.
