Our verdict
iExec offers confidential off chain compute through its PoCo Protocol with hardware enforced enclaves and onchain proof for every run. It suits developers and data owners who want to share protected datasets and run code without exposing underlying sensitive information for AI and custom logic workflows.
Pros and cons
Pros
- Encrypts datasets once for revocable access by app and user
- Runs code inside hardware enforced enclaves workers cannot read
- Records code, data and machine attestation onchain for every run
- Supports private AI inference, fine tuning and agents on hidden data
Cons
- Datasets need encryption and onchain registration before any sharing
- Execution relies on independent workers and consensus confirmation
- Access control is managed app by app and user by user
Who it suits
- Data owners sharing protected datasets with revocable access
- Developers building confidential AI and custom logic workflows
- Teams needing proof of code, data and execution machine
Who should look elsewhere
- People wanting fully public onchain logic and state
The company behind it
iExec has worked in confidential computing since 2017 and reports nine years of expertise in the field. The business centers on off chain execution where sensitive information stays hidden from compute providers. It maintains the PoCo Protocol which orders applications, executes them on protected data and settles activity with an onchain record. The approach addresses clear data exposure, missing execution attestation and public smart contract state. Development emphasizes hardware enforced confidentiality and verifiable outputs for data owners and builders.
Core features
Core operation starts when a dataset is encrypted once and registered onchain for app by app and user by user access that can be revoked at any time. Any code ships as an iExec app and executes inside a hardware enforced enclave on an independent worker without reading the raw data. Workers stake to contribute while consensus confirms results and settlement follows onchain. Each run returns only the output plus proof covering code, data and machine. DataProtector supports dataset rental with onchain permissions. AI coverage includes inference, fine tuning and agents where model and data stay hidden.
How iExec compares
Frequently asked questions
What is the PoCo Protocol?+
The PoCo Protocol orders applications, executes them on data they never see and settles the activity onchain. It uses hardware enforced confidentiality plus consensus confirmation from workers. Every run produces an output with an onchain proof of how it was created.
What does DataProtector do?+
DataProtector protects a dataset once and then rents access app by app and user by user. Permissions live onchain and can be revoked at any time. The raw data stays hidden while approved apps compute with it.
How does iExec keep data private during compute?+
Code ships as an iExec app and runs inside a hardware enforced enclave on an independent worker. The app can compute with the data without reading it, and the worker cannot extract it. Only the output leaves the enclave.
How is each run verified?+
Each run is confirmed by consensus among staking workers and recorded onchain. The record covers the code, the data and the machine that executed it. Users receive the output together with proof of how it was produced.
