Let's start with the basics

and explore how iExec can help you build Privacy-preserving applications and securely manage sensitive data.

👨‍💻 Building Privacy-preserving iApp with iExec

Imagine you're building a decentralized application (iApp) that needs to handle sensitive user data, for example:

🤖An AI model training on sensitive data

💰A financial app handling financial data

🔬A research platform working with private datasets

🏥A healthcare app processing confidential patient records

You'll need a way to:

🔒Keep the data confidential

🎮Control who can access it

⚡Process it securely

💎Potentially monetize it

This is where iExec comes in! We provide tools to easily add privacy and monetization features into your iApp.

👷 How do we Solve it?

Unlike traditional tools, iExec protects your data throughout its entire lifecycle - during storage, transfer, and even while being processed by applications.

This is made possible thanks to Trusted Execution Environment (TEE) and Confidential Computing technologies.

Our technology allows users to control the ownership, confidentiality, and monetization of their data and digital assets within the Web3 ecosystem.

🔒 The Three Key Elements?

iExec combines three fundamental elements that work together seamlessly:

1. Protect Data with our DevTool DataProtector

• Encrypt your sensitive data and store it securely on Arweave or IPFS
• Only you control who can access it and when
• Perfect for private information like research data, business analytics, or personal records

2. Compute Data with iExec Apps (iApp) Running in Secure Environment

• Special applications that can work with protected data
• Run in secure environments (called TEEs) that keep your data private
• Process data without exposing sensitive information

3. Set the Rules with the Blockchain Layer

• Enables tokenization of data
• Regain ownership of your data
• Provides transparent governance rules for data access

By merging blockchain technology with confidential computing, we've pioneered DeCC (Decentralized Confidential Computing) to take privacy and security to the next level in Web3 ecosystems.

🧸 DeCC Explained Like You're 5

Imagine a secure room, like a private bank vault for data, where everything inside stays safe and private.

With a tool called DataProtector, your data becomes protected and can only be read and processed inside this secure room.

Special applications called iApp (applications built to run in secure environments) can enter the room to work with your data. You stay in control by setting access rules that only you can modify about who can access it and when.

🔍 Building your First Privacy-preserving iApp

Let's meet Bob and Alice to understand how iExec enables Privacy-preserving applications:

1. Meet Bob: the iApp Developer 👨‍💻

Bob is building a decentralized application that uses iExec's technology. His platform consists of:

• A user-friendly interface for users.
• A DataProtector SDK that's easy to integrate into any application.
• Thanks to DataProtector, end users can protect their data, manage access, and process it seamlessly.

2. Meet Alice: the iApp User 👩‍💼

When using Bob's platform, Alice can:

• Protect her data using the Bob's platform's DataProtector feature
• Maintain full control over who can access her protected data
• Authorize specific iExec Apps and persons like Bob to use her data in a secure environment

Depending on the iApp's use case, Alice could:

• Apply algorithms to her data and get results confidentially
• Share her data with other users privately (and get paid for it)
• Ask questions to AI models about her data and get answers confidentially

And many other use cases...

🎯 Key Takeaways
