The Query Layer refers to a system or interface that allows users to interact with a blockchain by querying data without influencing the underlying transactions. It acts as a bridge between users and the blockchain, enabling them to retrieve information such as transaction details, wallet balances, or smart contract states.This layer facilitates data access through various methods, including APIs, which help developers build applications that can efficiently access blockchain data. It greatly enhances user experience by providing searchable capabilities and filtering options to locate specific information.By separating data retrieval from transaction execution, the Query Layer improves overall performance and scalability, reducing the load on the main blockchain network. This separation also allows for real-time data access, making it easier for users and applications to obtain timely information.
