Block chain transaction parallel processing method and system

Abstract

The invention discloses a block chain transaction parallel processing method and system, and the method comprises the steps: S1, dividing the transactions in a block into a plurality of groups, pressing the ordered locks of all accounts involved in the transactions in each group into the scheduling information of the respective thread, and enabling the ordered locks to be provided with a plurality of thread identifiers, wherein the thread identifier is used for identifying threads which need to execute transactions on the account and priorities of processing among the threads; S2, according to the priority of the thread identifier in the ordered lock of each account, each thread executing transaction of each group in parallel, the thread corresponding to the thread identifier with the highest priority in the ordered lock of each account preferentially executing transaction related to the account, and after the transaction is completed, the priority of the thread identifier in the ordered lock being updated, and the priority of the thread identifier in the ordered lock being updated. This is repeated until each group of transactions is performed. According to the method and the device, the sequence problem of multi-thread parallel processing of multiple transactions related to multiple accounts is solved, and the orderliness of parallel processing is guaranteed, so that the efficiency of parallel processing is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of blockchain, and in particular relates to a method and system for parallel processing of blockchain transactions. Background technique [0002] Based on its characteristics of unforgeability, traceability, traceability, openness and transparency, and collective maintenance, blockchain technology has realized a variety of functions in real life, not only guaranteed safety and reliability, but also greatly facilitated every aspect of real life. At the same time, it is precisely because of the unique characteristics of the blockchain that the simple transaction processing in reality has become very complicated in the blockchain, especially for the parallel processing of transactions, the existing transaction processing technology is not yet orderly, Safe and accurate parallel processing.

At the same time, it is precisely because of the unique characteristics of the blockchain that the simple transaction processing in reality has become very complicated in the blockchain, especially for the parallel processing of transactions, the existing transaction processing technology is not yet orderly, Safe and accurate parallel processing

[0003] Among them, when the existing technology generally processes multiple transactions in parallel, each account can only transfer or receive one transaction in one block, which is not only too restrictive for users, but also leads to low efficiency of transaction processing. This requires locking the account. When multiple threads process transactions involving the same account, each thread can lock the account through the account lock of the account when executing the transaction processing, so as to avoid other threads in parallel processing. Simultaneous processing of the account, causing confusion in transaction processing

[0004] However, there are still problems. When multiple transactions involved in an account require multiple threads to be executed in an orderly manner, the above method obviously cannot be executed in an orderly manner. At the same time, when multiple transactions in one thread involve the same account, After the thread executes one of the transactions, it is time to execute the remaining transactions involving the account in the current thread, and there will be parallel processing problems due to the transaction processing of other threads.
