In this blog, we will talk about how to build a decentralized cloud marketplace like iExec, highlighting essential features, core architecture, and the technologies needed to create a scalable and secure compute-sharing ecosystem. As we have helped businesses build and launch decentralized platforms across AI and blockchain domains, IdeaUsher has the expertise to guide you through creating a robust compute-sharing marketplace tailored to your use case.

What is Decentralized Cloud Marketplace iExec?

iExec is a blockchain-based decentralized cloud marketplace, sometimes called a “Meta Cloud.” It lets app developers, data providers, and infrastructure operators buy and sell computing resources, algorithms, and datasets peer-to-peer without central control. Powered by Ethereum and its RLC token, assignments match with providers through pay‑per‑task pricing. Off-chain computation is verified via Proof‑of‑Contribution (PoCo), ensuring result integrity and transparency.

Business Model

iExec runs a decentralized cloud marketplace with token incentives. Compute providers, or iExec Workers, supply spare CPU, GPU, or TEE resources, earning RLC tokens after task validation via proof-of-contribution (PoCo), ensuring trust. Application and data providers monetize AI models, algorithms, or datasets through pay-per-task or data rental in privacy-preserving environments. The Enterprise Edition supports private infrastructure, KYC/KYB compliance, and consulting for integrating decentralized compute into enterprise workflows.

Revenue Model

iExec sustains its ecosystem through multiple monetization streams that align incentives and encourage usage:

• Pay‑per‑task Fees: Users pay in RLC tokens for compute jobs. Providers and schedulers are rewarded only after work validation via PoCo. This makes processing power a peer-traded commodity.
• Data & AI Model Renting (Data Wallet): Dataset and AI model owners set usage fees for access. All execution happens in confidential environments (TEE), protecting intellectual property while generating royalties.
• Enterprise Licensing & Support: Customized deployments, consulting, and enterprise-grade services for corporate use cases, like private cloud on consortium chains.
• Developer Voucher & Ecosystem Rewards Program: A circular revenue-sharing model where voucher sales fund ecosystem activity, grants, and RLC incentives tied to usage growth and platform adoption.

How does iExec work?

iExec is a decentralized cloud marketplace linking users to idle resources and datasets via a secure, token-based system. It integrates off-chain efficiency with on-chain trust for real-time exchange and privacy-preserving execution.

1. Marketplace & Matchmaking

In iExec, users submit computation requests like machine learning tasks or analytics using the native RLC token. The platform uses decentralized schedulers to match requests with available iExec Workers offering CPU, GPU, or TEE nodes. This on-demand system forms the core of the decentralized cloud marketplace’s dynamic task allocation.

2. Off‑Chain Execution with TEE

Task execution on iExec occurs off-chain through XtremWeb‑HEP, a grid computing framework. Each job runs in a secure Trusted Execution Environment (like Intel SGX), preventing node operators from accessing sensitive data. This maintains enterprise-grade privacy in the decentralized cloud marketplace without sacrificing performance.

3. Proof-of-Contribution (PoCo)

After a task finishes, iExec uses a cryptographic protocol known as Proof-of-Contribution (PoCo) to validate that the work was performed correctly. Only when the system verifies legitimate results do providers receive RLC tokens. This not only ensures fair rewards but also discourages bad actors in the network.

4. Reputation & Incentives

Both workers and schedulers are ranked through an on-chain reputation system. Those who consistently complete accurate computations or assign tasks effectively earn stronger trust scores. This reputation layer reinforces the reliability of the decentralized cloud marketplace while guiding future task allocation.

5. Secure Data & App Monetization

iExec allows developers and data providers to earn RLC by renting their apps or datasets to others. The platform’s DataProtector tool encrypts assets before any off-chain execution and enforces access rules directly inside the secure enclaves. This allows safe monetization of intellectual property in a decentralized cloud marketplace environment.

6. Enterprise & Utility Extensions

The iExec Enterprise Edition brings added features for institutional use cases. It supports GPU compute via Genesis Cloud, multi-cloud deployment flexibility, zero gas fees through a dedicated sidechain, and compliance support. These extensions make the marketplace viable for both Web3 startups and established enterprises.
