The embodiment of the invention discloses a transaction processing method and device and a block chain system. An accounting node in a sub-block chain division corresponding to a transfer-out party account number receives a transaction request initiated by a client, and obtains relevant information of each sub-block chain division from the main block chain division; a sub-block chain partition corresponding to the account number of the transfer-in party is determined according to the relevant information; if the sub-block chain partition corresponding to the transfer-in side account number isdifferent from the sub-block chain partition corresponding to the transfer-out side account number, after the transfer-out side processes the transaction request, the transaction request is forwardedto the bookkeeping node in the sub-block chain partition corresponding to the transfer-in side account number, so that the transfer-in side processes the transaction request. On the basis of block chain partition, cross-partition transactions are realized. Each sub-block chain partition only needs to process transactions related to its corresponding account number, and multiple sub-block chain partitions can process transactions related to multiple account numbers in parallel, so transaction processing efficiency is improved.

The invention provides a concurrent transaction data processing method and device. The method comprises the steps of receiving concurrent transaction data (pre-purchased commodity identifiers and the number of pre-purchased commodities) submitted by multiple clients; deducting the residual number of the pre-purchased commodities from a limit table (the commodity identifiers and the corresponding residual number of the commodities) according to the commodity identifiers and the number of pre-purchased commodities submitted by one client; generating a transaction according to the transaction data when the residual number of the pre-purchased commodities is deducted successfully; carrying out a response that the client transacts successfully when the transaction is generated successfully; and carrying out the response that the client transacts unsuccessfully when the residual number of the pre-purchased commodities is deducted unsuccessfully or the transaction is generated unsuccessfully. Compared with the traditional mode that the same transaction is used for controlling deduction of the residual number of the pre-purchased commodities and generation of the transaction, the method and the device have the advantage that the control of two independent transactions is employed. According to the scheme, the time of responding to multiple client requests is reduced, and the transaction processing efficiency is improved.
