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.
