Problems solved by technology

[0004] The problem with the above technical solution is that the query function is a highly concurrent function, that is, when many users send many query requests at the same time, the process of running the blockchain needs to call multiple virtual machines concurrently and continue to execute transactions , leading to a decrease in the performance of executing transactions, thereby reducing the tps of the entire blockchain system

Abstract

The invention provides a data query method, computer equipment and a storage medium. The method comprises the following steps: receiving a first user query request; generating a first index query request according to the first jvm contract name and each first query parameter, and sending the first index query request to a first jvm query server, so that the first jvm query server loads a first jvm contract in the jvm according to the first jvm contract name, generates a first index according to each first query parameter, and returns the first index; receiving a first index, and querying a first query result in the blockchain database according to the first index; sending the first query result to a first jvm query server, so that the first jvm query server performs deserialization processing on the first query result in a jvm loading the first jvm contract to generate a second query result, and returning the second query result; and receiving a second query result, and returning the second query result to the first user side. The transaction execution performance is not influenced by high-concurrency calling of the virtual machine, and the tps of the blockchain system is improved.

Description

technical field [0001] The present application relates to the technical field of the Internet, in particular to a data query method, computer equipment and storage media. Background technique [0002] In the existing blockchain system, the smart contract of the blockchain needs to be executed in a virtual machine (eg, EVM, JVM, etc.). [0003] Taking the blockchain system that loads and executes smart contracts through the JVM as an example, when a blockchain node processes a query request, it needs to load the smart contract corresponding to the query request in the JVM. [0004] The problem with the above technical solution is that the query function is a highly concurrent function, that is, when many users send many query requests at the same time, the process of running the blockchain needs to call multiple virtual machines concurrently and continue to execute transactions , leading to a reduction in the performance of its transaction execution, thereby reducing the tps...
