Embodiment Construction

[0025] All features disclosed in all embodiments in this specification, or steps in all implicitly disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined and / or extended and replaced in any way.

[0026] Such as figure 1 , as shown in 2, a blockchain transaction parallel execution acceleration method, the specific implementation process is as follows:

[0027] Phase 1: Put the block to be submitted into the cache pool

[0028] In order to control the number of concurrency, the present invention creates a limited-capacity buffer pool for storing block queues that will be used to generate DAG. Assuming that the size of the DAG cache pool is 10, the present invention sequentially takes out 10 consecutive blocks from Block1 to Block10 and puts them into the DAG cache pool.

[0029] Phase 2: Generate DAG using blocks in the cache pool

[0030] The invention analyzes each block in the DAG cache pool to obtain the read-write set of eac...

Abstract

The invention discloses a block chain transaction parallel execution acceleration method. The method comprises the following steps: S1, putting a to-be-submitted block into a cache pool; S2, generating a directed acyclic graph (DAG) by using the blocks in the cache pool; S3, generating a submission queue according to a directed acyclic graph (DAG); S4, writing the blocks into files in parallel. According to the method and the device, the problems of low performance and relatively long transaction confirmation time of an existing block chain system are solved, parallel submission of the blocks is realized under the condition of ensuring that final transaction results are consistent, and a plurality of different blocks are concurrently written into different files.

Description

technical field [0001] The present invention relates to the technical field of block chains, and more specifically, to a method for accelerating parallel execution of block chain transactions. Background technique [0002] The existing blockchain system has the following problems: [0003] (1) Low performance. Since each decision-making node of the block system has to maintain a series of transaction status data, and the transactions executed in the block chain system often have a dependency relationship, the execution sequence of transactions with dependencies must be guaranteed to avoid different decisions. The transaction status data between nodes is inconsistent, so the block submission process of the existing blockchain system is often serial, resulting in low system throughput and unable to take advantage of multi-core computers. [0004] (2) The transaction confirmation time is longer. Since the block submission process in the existing blockchain system adopts a se...
