Step S104: and triggering a saving operation through the intelligent contract to save the node information in response to receiving the request for saving the node information.
Wherein triggering a node information saving operation by an intelligent contract for saving the node information comprises verifying the node information by the intelligent contract. And if the node information passes the verification of the intelligent contract, saving the node information. And if the node information is not verified by the intelligent contract, not saving the node information.
Step S105: sending the node information to a data point in the blockchain.
Wherein the data point may be any one of a plurality of departments in the block chain, wherein the departments include at least an endorsement node, a validation node, and a ranking node.
The department also comprises a CA node, wherein the CA node is used for carrying out authority management on the department.

And S203, sending a request for saving node information, wherein the node information comprises the model form.
Step S204: and triggering a saving operation through the intelligent contract to save the node information in response to receiving the request for saving the node information.
Step S205: sending the node information to a data point in the blockchain.
Step S206: a request to view node information is sent.
Step S207: and in response to receiving the request for viewing the node information, executing a query operation through the intelligent contract to return corresponding node information.
Step S208: comparing the hash values over the blockchain to the hash values under the blockchain to determine whether to display the model form.

It will also be noted that each block of the block diagrams or flowchart illustration, and combinations of blocks in the block diagrams or flowchart illustration, can be implemented by special purpose hardware-based systems which perform the specified functions or acts, or combinations of special purpose hardware and computer instructions.
The modules described in the embodiments of the present invention may be implemented by software or hardware. The described modules may also be provided in a processor, which may be described as: a processor comprises a node form filling module, a hash coding module, a request sending module, an intelligent contract module, a node information distribution module, a hash verification module and a display module. The names of these modules do not form a limitation to the module itself in some cases, for example, the node form filling module may also be described as a "module for filling a node form".
As another aspect, the present invention also provides a computer-readable medium that may be contained in the apparatus described in the above embodiments; or may be separate and not incorporated into the device. The computer readable medium carries one or more programs which, when executed by a device, cause the device to comprise: filling a model form for each of a plurality of nodes of a model to convert the filled model form into a JSON data format; encoding the JSON data format by using a hash algorithm to obtain a hash value of the JSON data format; sending a request for saving node information, wherein the node information comprises the model form; in response to receiving the request for saving the node information, triggering a saving operation through an intelligent contract to save the node information; and sending the node information to a data point in the block chain.
According to the technical scheme of the embodiment of the invention, the off-center management and storage are realized based on the block chain technology and the intelligent contract technology, the risk of tampering the model is effectively reduced, and the asset loss caused by single-point failure is avoided.
The above-described embodiments should not be construed as limiting the scope of the invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions can occur, depending on design requirements and other factors. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
