# Overview

## Introduction

Lightstreams is a data-sharing network designed specifically for web3 applications, featuring permissioned access control. It builds upon the [IPFS protocol](https://ipfs.tech/), which has been enhanced to include file access controls, adapting it for enhanced security and privacy needs. 

## Components

The technology stack of Lightstreams comprises several key components:

* [Smart Vault](/products/smart-vault.md) - This is a decentralized datastore that includes robust privacy controls, ensuring secure storage and controlled access to data.
* [Lightstreams SDK](/products/smart-vault/sdk.md) - A comprehensive Software Development Kit that facilitates interaction with a Lightstreams node, simplifying the development process for developers.
