Abstract: Provided are a transaction request construction method and apparatus, a transaction request processing method and apparatus, a device and a storage medium, which relate to the field of blockchain technology and can be used for cloud computing and cloud services. A specific implementation includes: generating a standard transaction request according to a standard key of a service application party, to-be-processed request data, a target blockchain architecture to be accessed and a target blockchain identifier; and calling a transaction conversion service and converting the standard transaction request into a target transaction request under the target blockchain architecture according to the standard key, the target blockchain architecture and the target blockchain identifier; where the target transaction request is used for processing the to-be-processed request data. Transaction request construction and processing efficiency can be improved.

Abstract: Provided are a method for training a model based on homomorphic encryption, a device, and a storage medium. The specific implementation is: acquiring homomorphic encrypted data in a model training process; determining a hyperparameter of a model approximation function according to state data present in the model training process, where the model approximation function is used for replacing a model original function involved in the model training process; and inputting the homomorphic encrypted data to the model approximation function for calculation, and performing model training according to a calculation result. Therefore, the application flexibility of functions is improved while achieving the protection of data privacy in the model training process.

Abstract: Provided are a blockchain-based data verification method and apparatus, a device, and a storage medium, relating to the field of computer technology, for example, a blockchain technology, and applicable to cloud computing and cloud services. The solution includes acquiring a data verification transaction request initiated by a data owner; generating a response signature value in the current verification round according to the data verification transaction request; and sending the response signature value to a blockchain network. The response signature value is configured to instruct the blockchain network to verify whether the to-be-verified data block is stored in a data storer.
