Blockchain-based data processing method, device, and readable storage medium

A computer device, comprising a memory and one or more processors, the memory storing computer-readable instructions that, when being executed, cause the one or more processors to perform:

• obtaining a transaction on-chain request carrying a business transaction transmitted by a business device, determining a transaction execution result corresponding to the business transaction based on the transaction on-chain request, and performing on-chain processing on the transaction execution result and the business transaction;
• generating business transaction digest information corresponding to the business transaction based on a transaction sequence number, a business type identifier, and the transaction execution result in response to the transaction execution result and the business transaction being successfully stored in a side blockchain in a consortium blockchain, the transaction sequence number being used for representing a sequence number of the business transaction in the side blockchain, and the business type identifier being used for representing a business type of a business processed by the side blockchain;
• and
• transmitting the business transaction digest information to a main blockchain to store the business transaction digest information.

A non-transitory computer readable storage medium containing computer-readable instructions that, when being executed, cause one or more processors to perform:

• obtaining a transaction on-chain request carrying a business transaction transmitted by a business device, determining a transaction execution result corresponding to the business transaction based on the transaction on-chain request, and performing on-chain processing on the transaction execution result and the business transaction;
• generating business transaction digest information corresponding to the business transaction based on a transaction sequence number, a business type identifier, and the transaction execution result in response to the transaction execution result and the business transaction being successfully stored in a side blockchain in a consortium blockchain, the transaction sequence number being used for representing a sequence number of the business transaction in the side blockchain, and the business type identifier being used for representing a business type of a business processed by the side blockchain;
• and
• transmitting the business transaction digest information to a main blockchain to store the business transaction digest information.
