Abstract: A computer device obtains a block proposal message and obtains a first block from the block proposal message. In accordance with a determination that a current consensus node of the computer device has a second block in a locked state and a block height of the first block is the same as a block height of the second block, the computer device deletes the block proposal message and obtains block voting information of the second block in a first consensus stage. The locked state is a state of a block that has passed the first consensus stage and has not passed a second consensus stage. The computer device obtains block submission voting information of the second block in the second consensus stage according to the block voting information, and determines a consensus result corresponding to the second block according to the block submission voting information.

Abstract: A blockchain-based data processing method, apparatus, device, and readable storage medium may avoid repeated transmission or storage of the transaction data, which avoids a waste of storage resources. Target transaction data is obtained from a transaction pool, and a to-be-checked hash value of the target transaction data is generated. A block list of historical blocks that have been uploaded to a blockchain is obtained, and an upload status of the target transaction data is determined according to the block list and the to-be-checked hash value. Based on this determination, the target transaction data may be deleted when the upload status of the target transaction data is in an uploaded state, or a target block is generated and uploaded according to the target transaction data when the upload status of the target transaction data is in an un-uploaded state.

Abstract: A computing device transmits, to a second node, first consensus voting information for a target block. The device receives, from the second node, second consensus voting information for the target block. The device determines a consensus result for the target block according to the first and second consensus voting information. In accordance with a determination that the consensus result is a consensus success result, the device activates an accounting duration window. The device performs accounting processing on the target block in the predetermined time duration of the accounting duration window. The device receives, from the second node, a first accounting completion message for the target block transmitted by the second node in the accounting duration window. In accordance with a determination that accounting processing on the target block is completed in the accounting duration window, the device transmits a second accounting completion message to the second node.

Abstract: Embodiments of this application provide a data synchronization method and apparatus in a distributed system, a computer-readable medium, and an electronic device. The method includes: obtaining historical data synchronization information of adjacent nodes connected to a target node and determining selection weight values of the adjacent nodes according to the historical data synchronization information. The selection weight values are used for measuring efficiency of the adjacent nodes synchronizing data to the target node to select, according to the selection weight values of the adjacent nodes, a target adjacent node for synchronizing data to the target node. Target data is synchronized from the selected target adjacent node with the target node.
