In particular, when there is a block in the blockchain that is identical to the application program interface information, the node identification information is associated with the existing application program interface information of the block. This has the advantage that nodes using the same application program interface can share the same piece of information, so that an application program can call the application program interface and its implementation method through any node having the same application program interface.

As described above, the method for issuing transactions of intelligent contracts first searches for whether there is a block corresponding to the node application program interface information in the blockchain according to the received node identification information and application program interface information, and stores the node identification information and application program interface information in the blockchain when there is no block. In particular, when there is a block in the blockchain that is identical to the application program interface information, the node identification information is associated with the existing application program interface information of the block. It should be understood that nodes using the same application program interface may share the same piece of information so that an application program can call the application program interface and its implementation method through any node having the same application program interface.
