# Overview

Here we'll explain about how to create off-data verification applications with **NexaID SDKs**. Note all applications using NexaID SDKs are interacted with NexaID, a.k.a., decentralized attestors, where the attestations are generated in a decentralized process with a high hardware security level.

With the vision of creating a decentralized data verification and computation network, NexaID provides developer tools to help applications leverage zkTLS capability from the network attestors.

* For web-based applications, we recommend to use the **Network-JS-SDK** (see the [DApp Integration Guide](/nexaid/build-on-nexaid/dapp-integration/example.md) ). This is the most straightforward tool that allows end users to create zkTLS attestations through this SDK. Note the end user is required to install [NexaID extension](/nexaid/build-on-nexaid/extension/prerequisites.md) to perform the zkTLS session with the network attestor.
