Problems solved by technology

[0003] The current defect of data query through the Merkle tree is that querying the data of a transaction requires multiple read operations. For example, for a 20-layer Merkle tree, querying the data of a leaf node requires 20 read operations. Each read operation is completed, so the efficiency of data query is only 1 / 20 of the query efficiency of ordinary databases. For a system that can complete 100,000 read operations per second, only 5,000 transaction data can be read per second, which greatly limits read performance of the system

Embodiment Construction

[0038] The application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain related inventions, rather than to limit the invention. It should also be noted that, for ease of description, only parts related to the invention are shown in the drawings.

[0039] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0040] In this embodiment, each node of the blockchain network stores the Merkle tree of each block, and the global index table corresponding to the Merkle tree of each block, the above-mentioned Merkle tree and the global The index table takes the block height H as the version number.

Abstract

The invention provides a data inquiry method and system, consensus method and system, apparatus and storage medium. Each node of a block chain network respectively stores a Merkel tree of each block,and a global index table corresponding to the Merkel tree of each block. The version number of the version is a block height, wherein the query instruction includes the queried first block height; a target data is look up in that global index table according to the height of the first block. By configuring the corresponding Merkel tree, The global index table with the block height as the version number, and searching the target data in the global index table through the queried block height, can complete the query of the sub-node data of Merkel tree leaf in the block chain through one read operation, thus greatly improving the data reading performance of the system.

Description

technical field [0001] This application relates to the technical field of blockchain, and specifically relates to a data query method and system, a consensus method and system, equipment, and storage media. Background technique [0002] In the current data reading and writing solutions of the blockchain system, the structure of the Merkle tree is usually used. Kerr prefix tree (Merkle Patricia Tree, referred to as MPT) for data reading and writing, and so on. [0003] The current defect of data query through the Merkle tree is that querying the data of a transaction needs to be completed through multiple read operations. For example, for a 20-layer Merkle tree, querying the data of a leaf node requires 20 Each read operation is completed, so the efficiency of data query is only 1 / 20 of the query efficiency of ordinary databases. For a system that can complete 100,000 read operations per second, only 5,000 transaction data can be read per second, which greatly limits system...
