the scoring node is respectively connected with the recording node and the corresponding registration device and is used for receiving and verifying the validity of a first block sent by the recording node, receiving the scoring result of the scorer and receiving and verifying the validity of a first digital signature sent by the registration device, after the validity of the first digital signature sent by the registration device is verified, digitally signing the scoring result through a pre-stored second private key to obtain a second digital signature, recording the scoring result, the second digital signature and the received random identity information into the block head of the received first block, updating the first block into a second block, and sending the second block to the corresponding recording node;
the recording node is further configured to receive and verify validity of the second block sent by each relevant scoring node, to count a sum of scoring scores of each scoring node corresponding to each third block validated, to record the counted sum of scoring scores into a block header of the received second block, to store the currently updated second block, and to send the currently updated second block to other recording nodes.
6. The public scoring system based on a blockchain network according to claim 5, wherein the number of the recording nodes is at least 2, and when any one recording node sends the first block to the scoring node, other recording nodes do not have the right to send the first block.
7. The system according to claim 5, wherein the recording node comprises:
the first sending module is used for sending the first block to each scoring node;
the first receiving module is used for receiving the second blocks sent by all the scoring nodes;
the first verification module is used for verifying the validity of each second block received by the first receiving module;
and the processing module is used for counting the sum of the scoring scores of the scoring nodes corresponding to the second blocks which are verified to be valid by the first verification module, recording the counted sum of the scoring scores into the block head of the received second block, storing the currently updated second block, and sending the currently updated second block to other recording nodes.
8. The public scoring system based on a blockchain network according to claim 5, wherein the scoring node comprises:
the second receiving module is used for receiving the first block sent by the recording node;
the second receiving module is used for receiving the random identity information and the first digital signature sent by the registration device;
the scoring result acquisition module is used for acquiring scoring results submitted by a grader;
the second verification module is used for verifying the validity of the first block received by the second receiving module;
the third verification module is used for verifying the validity of the first digital signature received by the second receiving module;
the second processing module is used for carrying out digital signature on the scoring result acquired by the scoring result acquisition module through a prestored second private key to obtain a second digital signature after the second verification module verifies that the validity of the first block passes, and is used for recording the scoring result, the second digital signature and the random identity information received by the second receiving module into the block head of the first block received by the second receiving module to update the first block into a second block;
and the second sending module is used for sending the updated second block in the second processing module to the corresponding recording node.
9. The public scoring system based on a blockchain network according to any one of claims 5 to 8, wherein the registering means is a registering device or a server.
