# Node Roles

Cortensor's decentralized AI ecosystem relies on a network of interconnected nodes, each with specific roles to ensure seamless operation and efficiency. This overview details the key roles within the Cortensor network:

### Router Nodes

**Primary Function**: Bridge users and miner nodes, managing task allocation and communication.

**Key Responsibilities**:

* Allocate AI inference tasks to appropriate miner nodes based on their capabilities.
* Ensure secure, encrypted communication between users and miners.
* Manage user sessions, including payment verification and resource allocation.
* Provide interfaces compatible with both Web2 (REST API) and Web3 (SDK).

**Critical Tasks**:

* Optimize task distribution for maximum efficiency.
* Manage session lifecycles and user interactions.
* Maintain data security and privacy through encryption.

### Miner Nodes

**Primary Function**: Execute AI inference tasks and participate in network validation.

**Key Responsibilities**:

* Perform AI inference using various models on diverse hardware (from low-end devices to high-end GPUs).
* Collaborate in task execution and result validation.
* Participate in proof of inference processes.
* Stake tokens and earn rewards based on contributions and performance.

**Critical Tasks**:

* Execute AI inference tasks efficiently.
* Validate results and ensure network accuracy.
* Build and maintain performance-based reputation.

### Clients/Users

**Primary Function**: Initiate and manage AI inference requests.

**Key Responsibilities**:

* Create and manage sessions by depositing tokens (calculated in LLM tokens).
* Submit AI inference requests via smart contracts or REST API.
* Retrieve inference results through secure channels.
* Configure validation requirements for tasks.

**Critical Tasks**:

* Manage AI inference sessions.
* Submit tasks and securely receive results.
* Balance cost and accuracy through validation configuration.

### Oracle/Master Guard Nodes

**Primary Function**: Maintain network timing and oversee block production.

**Key Responsibilities**:

* Track time and manage virtual block production.
* Ensure consistency in network operations and task execution.
* Potentially incorporate high-stakes mining responsibilities.

**Current Status and Future Plans**:

* Initially hosted by the Cortensor team.
* Plans to transition to a permissionless model or integrate with high-stake miner nodes.
* Final implementation details are still to be determined.

**Critical Tasks**:

* Maintain network synchronization.
* Oversee block timing and production.
* Contribute to network stability and reliability.

**Note**: The exact implementation of oracle/master guard nodes is subject to change as the Cortensor network evolves. The team is exploring options to further decentralize this role, potentially by integrating it with existing miner nodes or creating a new class of high-stake nodes with additional responsibilities.
