the second registration module is used for judging whether the received second signature data is legal or not, if so, a certificate storage structure is constructed according to the second signature data and the timestamp and is stored in a list to which the intellectual property rights belong in the local memory pool, and registration success information is returned to the client side, otherwise, an error is reported;
the broadcasting module is used for broadcasting a process of a data block containing a certificate storing structure body, and specifically comprises:
the first judging unit is used for judging whether the node is an offered node or not, if so, the detecting and judging unit is triggered, and if not, the processing unit is triggered;
the detection judging unit is used for judging whether data exist in the local memory pool or not when the data block needing to be broadcasted is detected, if so, triggering the first broadcast generation unit, otherwise, broadcasting an empty data block, and triggering the first judging unit;
the first generating and broadcasting unit is used for broadcasting the proposal containing the data block according to the generating data block in the local memory pool and triggering the second generating and broadcasting unit; the data in the local memory pool comprises a storage certificate structure body;
the second generation broadcasting unit is used for generating a pre-voting block according to the data block and broadcasting the pre-voting block, generating a pre-submission block according to the data block and broadcasting the pre-submission block when the received pre-voting result meets a preset requirement, submitting the data block when the received pre-submission block meets the preset requirement, increasing the height of the data block in the area, and triggering the first judgment unit;
the processing unit is used for storing the data block in the proposal if the proposal is received, triggering the first judging unit, verifying the pre-voting block if the pre-voting block is received, broadcasting a pre-voting result if the verification is successful, triggering the first judging unit, and broadcasting a pre-submitting block result if the pre-submitting block is received, triggering the first judging unit.
