- **Blockchain Security** – Smart contracts ensure fair and transparent transactions while eliminating intermediaries.  
- **Flexible Computing Solutions** – Supports scientific research, machine learning, IoT, and enterprise computing applications.  
- **Confidential Computing** – Uses secure enclaves (Trusted Execution Environments) to protect sensitive data and private computations.

Question 3

Who Created iExec?

Accepted Answer

iExec was founded in **October 2016 in France** by **Dr. Gilles Fedak, Dr. Oleg Lodygensky, and Dr. Haiwu He**, alongside a team of blockchain and cloud computing experts based in Lyon.

The founders have **strong academic and industry backgrounds** in **distributed computing and blockchain security**, leading to the development of iExec as a **pioneering decentralized cloud platform**. Their vision was to create an ecosystem where **computing resources are democratized** and **accessible to users worldwide** through blockchain technology.

Question 4

How Does iExec Work?

Accepted Answer

iExec operates as a **decentralized cloud computing marketplace**, where users and providers interact through **smart contracts and blockchain-based transactions**.

- **Users (Requesters)** – Individuals or businesses that need computing power **submit tasks and pay providers** using **RLC tokens**.  
- **Providers (Workers)** – Resource owners list their computing power (CPU/GPU) on the marketplace and execute tasks **in exchange for RLC rewards**.  
- **Blockchain Integration** – Transactions are recorded on **Ethereum’s blockchain**, ensuring **transparency, automation, and security**.

Question 5

What is the Role of the Proof-of-Contribution (PoCo) Consensus Protocol?

Accepted Answer

The **Proof-of-Contribution (PoCo)** protocol is iExec’s **consensus mechanism** designed to **verify and validate off-chain computations** in a decentralized manner.

- **Task Validation** – PoCo ensures that computational tasks are executed **correctly and fairly** by requiring providers to submit **proof of their work** on-chain.  
- **Reputation and Rewards** – Providers are assigned a **reputation score** based on their performance. Honest participants receive **staking rewards**, while malicious actors risk **penalties or exclusion**.  
- **Trustless Execution** – Smart contracts automatically **release payments** to providers only after their work is **verified as valid**.

Question 6

What Are iExec’s Privacy-Preserving Features?

Accepted Answer

iExec prioritizes **data privacy and security** by integrating **confidential computing technologies** such as **Trusted Execution Environments (TEEs)**.

- **Secure Enclaves (Intel® SGX)** – Computations are executed inside **isolated, tamper-proof environments**, preventing even the node operator from accessing sensitive data.  
- **Confidential AI & Data Processing** – Users can run machine learning models or analytics **without exposing raw data** to third parties.  
- **Decentralized Confidential Computing** – Ensures that **private computations remain encrypted**, addressing security concerns in cloud computing.

Question 7

In Addition to Providing Computing Power, What Else Does iExec Offer?

Accepted Answer

Beyond cloud computing, iExec expands its **marketplace ecosystem** to include additional **digital assets and AI tools**.

- **AI Model & Data Marketplace** – Users can **buy, sell, and rent** **pre-trained machine learning models and datasets** for AI-driven applications.  
- **Decentralized Data Monetization** – Organizations can **sell proprietary data sets securely**, allowing trusted access **without full ownership transfer**.  
- **Blockchain for Enterprise & Web3** – iExec supports **decentralized applications (dApps)** with computing infrastructure, enabling **Web3 scalability**.
