s101: the blockchain system determines the data tag based on the received transaction request information.
After receiving the transaction request information sent by the user, the blockchain system can be stored in a transaction cache queue first, and the transaction request information is obtained from the head of the queue each time.
S102: the blockchain system selects a plurality of intelligent contracts from the intelligent contract set corresponding to the data tag, and sends transaction request information and an intelligent contract registration form of each intelligent contract to a contract container corresponding to the intelligent contract.
Wherein the intelligent contracts selected by the blockchain system comprise a system intelligent contract and a plurality of user intelligent contracts;
when the contract type is at a system level, the blockchain system generates a system intelligent contract;
when the contract type is user-level, the blockchain system generates a user-intelligent contract.
When there is no data tag in the transaction request information, the blockchain system may select a plurality of intelligent contracts from the data domain. The user can set the proportion between the system intelligent contracts and the user intelligent contracts in the transaction request information, and when the proportion exceeds the maximum number of the user intelligent contracts corresponding to the data field, all the user intelligent contracts corresponding to the data field are selected.
S103: each contract container generates an execution result according to the intelligent contract registry and the transaction request information, and sends the execution result to the blockchain system.
S104: the blockchain system merges the execution results corresponding to the same transaction ID into a test result, and writes the test result into the newly generated block.
In the implementation, a transaction ID corresponds to a block, and a user can obtain a test result by querying the block corresponding to the transaction ID.
The execution subject of the blockchain-based assessment method shown in fig. 1 may be a blockchain system including a plurality of nodes and a plurality of contract containers. As can be seen from the flow shown in fig. 1, the blockchain system in the blockchain-based evaluation method according to the embodiment of the present invention determines a data tag according to the received transaction request information, and selects a plurality of intelligent contracts from the intelligent contract set corresponding to the data tag, and sends the transaction request information and the intelligent contract registration form of each intelligent contract to the contract container corresponding to the intelligent contract; the contract container generates an execution result according to the intelligent contract registration form and the transaction request information, and sends the execution result to the blockchain system; the blockchain system combines the execution results corresponding to the same transaction ID into a test result, and writes the test result into the newly generated block, so that the true reliability of the experimental result can be verified.
In one embodiment, all data (e.g., smart contract deployment requests, transaction request information, etc.) uploaded to the blockchain by the user needs to be encrypted, and the system can decrypt the encrypted data before further processing. The encryption and decryption flow is as follows:
1. the user invokes the blockchain system encryption interface and the blockchain system transmits its own public key PubS to the user.
2. After the user takes the public key PubS, the user encrypts the data by using the public key PubS to obtain the ciphertext. The user signs the ciphertext by using the private key PrIC, prevents the ciphertext from being tampered in the transmission process, and sends the public key PubC to the blockchain system for signature verification.
3. After the block chain system receives the encrypted data sent by the user, firstly, the public key PubC is used for verifying the ciphertext, and if the ciphertext is tampered in the middle, the verification is not passed. After the verification passes, the block chain system uses the private key PrIS of the system to decrypt the ciphertext.

Aiming at the problem of checking the authenticity of the current industrial scientific research achievements, the invention provides an operation platform and encourages users to share the encrypted technical source code by integrating the test data set disclosed in each field and the private test data set of the users, links the intelligent contract with the test data set by utilizing the characteristics of the contract container, and simultaneously executes the technical model program in the contract container to finally obtain the test result. The whole data transmission process has confidential operation, and the isolation of the contract container can not enable the outside to directly acquire the internal data, so that the purposes of sharing data and source codes and protecting privacy and intellectual property are achieved, and the true reliability of experimental results can be verified.
In summary, the blockchain-based evaluation method of the embodiment of the invention has the following beneficial effects:
(1) The smart contract is combined with the test dataset: through the contract container, the test data set is stored in the contract container, while the source code of the technical model program must also run in the contract container. Because of the isolation of the contract container, the test data set and the source code are isolated from the outside in the whole execution process, and cannot be tampered. Besides, the disclosed test set is transparent to the user disclosure, the test data set issued by the user is blocked for other users, the user cannot view the test data set issued by other users, the user test data set is shared, the user privacy data is ensured, and the user can use the test data set of other users through the blockchain system but cannot occupy the existing state.
(2) Intelligent contract execution technology model program: the user uploads the encrypted technical model program and runs in the contract container, which provides a good environment in which the user can use other user test data and run his own code, as other users cannot acquire the code executed in the contract container. According to the execution results of the technical model program on different data test sets, a user can optimize and improve the technical model program, and the adaptability of the program is improved.
(3) Multi-intelligent contract, multi-test set verification: most of the public test data sets actually have better data quality than the personal data sets of users, but the technical models with better performance on the public data test sets in the past usually cannot achieve the effect of the public test when used in the actual application scene. The invention uses a plurality of intelligent contracts to test a plurality of test data sets, can avoid single test on the open test data sets, and more comprehensively verifies the technical model program, so that the test result is more convincing and credible.
Based on the same inventive concept, the embodiment of the invention also provides a block chain-based evaluation system, and because the principle of solving the problem of the system is similar to that of the block chain-based evaluation method, the implementation of the system can refer to the implementation of the method, and the repetition is omitted.
