Problems solved by technology
[0003] Consortium chain event monitoring means that the software development kit (Software Development Kit, SDK) client monitors the consortium chain events sent by the consortium chain network in a long-connected manner, and when the business system monitors the event, it uses this to perform business logic Due to the reasons of the network or the SDK client itself, the block event will be lost. In the existing technology, regular polling is used to query the block data from the alliance chain network, and then process the business logic and record it to The database method has low real-time performance and low performance

The present application provides a method, device, device and storage medium for determining a lost block of a consortium chain, including: obtaining the prehash value of the current block to be written in the consortium chain event being monitored; querying the target in the block storage database the hash value of the block, and detect whether the prehash value of the current block is the same as the hash value of the target block; if the prehash value of the current block is not the same as the hash value of the target block, then Select the block of the alliance chain event sequentially from the current block forward, and match the prehash value corresponding to the currently selected block with the hash value of the target block until the prehash value of the currently selected block matches the Until the hash value of the target block is the same, the currently selected block whose prehash value is the same as the hash value of the target block is determined as a matching block; The block is determined to be a lost block. This application has strong real-time performance and high performance, and improves the speed and accuracy of lost block recovery.
Description
technical field [0001] The present application relates to the field of communication technologies, and in particular to a method, device, computer equipment and storage medium for determining lost blocks of a consortium chain. Background technique [0002] The alliance chain is only for members of a certain group and a limited number of third parties. Multiple pre-selected nodes are internally designated as bookkeepers. The generation of each block is jointly determined by all pre-selected nodes, and other access nodes can participate in transactions. However, without asking about the accounting process, other third parties can make limited queries through the Application Programming Interface (API) opened by the alliance chain. In order to obtain better performance, the consortium chain has certain requirements for the configuration and network environment of consensus or verification nodes. With the access mechanism, it is easier to improve transaction performance and avo...
