A method, apparatus, and computer-readable storage medium for transaction processing in a blockchain network. The method includes receiving a first transaction from a client via a target processing node, and extracting information of a target type that is not needed during consensus processing or post-consensus execution. A local contract deployed in the target processing node processes this extracted information to obtain a processing result. A transition transaction is generated based on the processing result and remaining information from the first transaction, and transmitted to the client. The transition transaction is signed cooperatively using private key fragments stored in both the client and processing node to obtain a transaction signature. A second transaction is then generated based on this signature and the transition transaction, and transmitted to the consensus network for consensus processing.

Embodiments are directed to the tracking of data in a generative adversarial network (GAN) model using a distributed ledger system, such as a blockchain. A learning platform implementing a classification model receives, from a third party, a set of data examples generated by a generator model. The set of data examples are processed by the classification model, which outputs a prediction for each data example indicating whether each data example is true or false. The distributed ledger keeps a record of data examples submitted to the learning platform, as well as of predictions determined by the classification model on the learning platform. The learning platform analyzes the records of the distributed ledger, and pairs the records corresponding to the submitted data examples and the generated predictions determined by the classification model, and determines if the predictions were correct. The classification model may then be updated based upon the prediction results.

A method for digital currency intra-chain and cross-chain off-chain payments based on trusted hardware. By creating and transferring a public-private key pair saved and managed by a trusted hardware system to replace the on-chain payment, the trusted hardware ensures the security of the transaction, avoids complicated on-chain transaction steps, reduces the long on-chain transaction time and high on-chain transaction cost, and neglects the differences among blockchain systems to support cross-chain transactions, thus greatly improving the intra-chain and cross-chain off-chain payment efficiency in digital currency and greatly reducing the payment cost in digital currency. In addition, on the basis of the above payment method, the corresponding rescue object generation process of different digital currency types and the process of using the rescue object to retrieve digital currency are further proposed, which avoids the problem of asset loss caused by the damage or loss of trusted hardware.
