Abstract

The embodiment of the invention discloses a data summarization method and device based on a tree block chain network, equipment and a medium. The method comprises: when it is detected that a pre-deployed summary contract is triggered, the node attribute of a tree node corresponding to a target block chain network where the tree node is located in a tree hierarchical structure is acquired; processing the data in the target block chain according to a data summarization strategy matched with the node attribute to form target summarized data; and if it is determined that the node attribute is a non-root node, sending the target summarized data to a parent block chain network of the target block chain network through a cross-chain protocol. According to the technical scheme provided by the embodiment of the invention, based on cross-chain interaction between parent and child block chain networks and a tree layering technology, the performance and storage bottleneck of a traditional single-chain structure are broken through, the problem of information islands incompatible with each other between different block chain networks is solved, and extensible application scenarios such as multi-service chains and polymorphic chains can be supported.

Description

technical field [0001] Embodiments of the present invention relate to blockchain technology, and in particular to a data collection method, device, device and medium based on a tree-shaped blockchain network. Background technique [0002] Blockchain technology is being recognized and paid attention to by more and more people. Because of the integration of technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm, it can effectively solve the fraudulent behavior of data in the system in the traditional transaction mode, and can reduce costs, simplify processes, and reduce unnecessary transaction costs and institutional costs. However, the current blockchain technology is still in its early stages. Whether it is technological innovation or commercial application, there are still many unresolved problems, which hinder the large-scale application of this technology. [0003] Today's blockchains, such as Bitcoin or...
