Abstract

The invention provides a hierarchical DAG block chain generation method and device, a medium and a program product, and the method comprises the steps: packaging a plurality of to-be-executed blocks which can be executed in parallel from a transaction pool when a block chain node is determined to be a packaging node corresponding to a new parallel block layer; then combining a plurality of blocks to be executed into a new parallel block layer; and the new parallel block layer is broadcasted in the block chain network, so that all nodes in the block chain network independently start a corresponding execution process, a consensus process and a disk falling process for each to-be-executed block. According to the method, the technical problem that the processing efficiency is reduced due to repeated block packaging and repeated block execution of each block chain node in the prior art is solved in a manner of circularly and alternately packaging the blocks which can be executed in parallel by each block chain node. The technical effects that the block chain nodes are prevented from packaging the blocks in parallel, so that the blocks do not meet the requirements of the DAG directed acyclic graph, and repeated packaging and repeated execution of the blocks are avoided are achieved.

Description

technical field [0001] The present application relates to the field of financial technology (Fintech), in particular to a method, device, medium and program product for generating a hierarchical DAG block chain. Background technique [0002] With the development of computer technology, more and more technologies are applied in the financial field, and the traditional financial industry is gradually transforming into financial technology (Fintech). Blockchain technology has also been widely used in the field of financial technology. [0003] At present, the blockchain generally uses a chain structure to store the blocks corresponding to each exchange. However, with the continuous improvement of the processing efficiency requirements of the blockchain system, the chain structure can no longer meet the efficiency requirements, and DAG appears. (Directed Acyclic Graph) blockchain, which improves the processing efficiency of the blockchain system by executing multiple blocks in ...
