In the embodiment of the application, the block account book in the block generation node is generated according to all intelligent contracts in the packaging consensus time, namely, the block production node packages all intelligent contracts in the consensus time to generate the block account book, and then the block account book is sent to the block synchronization center node, so that the block synchronization center node selectively synchronizes the block account book to other block nodes.
In the process of packaging the intelligent contracts, the block generating node needs to determine corresponding block abstract information and block importance level information according to the content of the packaged intelligent contracts, then count the storage space size required by the packaged intelligent contracts, and package the block abstract information, the space size data required by the blocks and the block importance level information as block headers together with the intelligent contracts in the consensus time to obtain the block ledger.
S20, determining block nodes corresponding to the data types according to the block abstract information.
Each block node correspondingly stores a block account book with a data type, wherein the data type can be specifically set according to actual conditions, for example, the data type can be specifically a bank data type, an insurance data type, a shopping data type, a catering data type and the like, and the embodiment of the application is not specifically limited. In the embodiment of the application, the block nodes of the corresponding data types can be determined according to the block abstract information of the block ledger, and the block nodes of the corresponding data types of the block ledger are determined specifically through a keyword recognition technology, for example, keyword recognition is performed on the block abstract information to obtain a keyword 'insurance', namely, the corresponding data types can be determined to be insurance data types through the keyword, so that the block nodes of the insurance data types corresponding to the block ledger are obtained.
As shown in fig. 2, in one embodiment provided by the present application, step S20: the determining the block node corresponding to the data type according to the block summary information comprises the following steps:
