+
+# Deal
+
+A **deal** is the core coordination mechanism in the iExec network. It brings
+together all the necessary components—requesters, applications, data, and
+computational resources to execute secure computations in TEE environments.
+
+## What is a Deal?
+
+When you want to run a computation on iExec, you don't directly interact with
+workers or applications. Instead, the **PoCo (Proof of Contribution)**
+decentralized smart contract automatically creates a deal that:
+
+- Matches your request with compatible resources
+- Coordinates all network actors (requester, app provider, data provider,
+  workerpool)
+- Ensures secure execution in TEE environments
+- Handles result delivery
+- Manages payment distribution
+
+## Deal Execution Flow
+
+When a deal is triggered, the following sequence occurs:
+
+1. **Request Creation**: Requester submits a computation request with parameters
+2. **Resource Matching**: PoCo system matches the request with available
+   applications, data, and computational resources
+3. **Deal Creation**: When the system finds compatible resources, it creates a
+   deal containing multiple tasks
+4. **Task Distribution**: Selected workerpool manager distributes tasks to their
+   workers
+5. **Secure Execution**: Workers download the iApp and execute it in TEE
+   environments
+6. **Data Processing**: iApp processes protected data without accessing raw
+   content
+7. **Result Generation**: Computation results are generated
+8. **Result Delivery**: Results are returned to the requester through the
+   network
+9. **Payment Settlement**: RLC tokens are distributed to all participants
+
+## Network Architecture
+
+The diagram below illustrates how different actors interact in the iExec
+network:
+
+![iExec Network Actors](/assets/use-iapp/iexec-actors-diagram.svg)
+
+## Detailed Interaction Flow
+
+1. **Request Submission**: Requester creates a request specifying the iApp,
+   Protected Data, and other parameters
+2. **PoCo Processing**: PoCo system validates the request and matches available
+   resources
+3. **Deal Creation**: When resources are matched, PoCo creates a deal containing
+   tasks
+4. **Secure Environment Setup**: Workers initialize TEE environments and
+   download the iApp
+5. **Data Access**: iApp requests access to protected data through secure
+   channels
+6. **Computation**: iApp processes data within the TEE, maintaining privacy
+7. **Payment Distribution**: RLC tokens are distributed to all participants
+   based on completed tasks
+
+This decentralized architecture ensures that no single entity has control over
+the entire process, while the use of TEEs guarantees that sensitive data remains
+protected throughout the computation.
