# 2. The RouterLink Ecosystem: Demand · Supply · Routing

RouterLink decomposes the AI ecosystem into three explicit roles that interact through protocol rules rather than organizational trust.

## Demand — Users and Developers

Users interact through a **single unified gateway**, abstracting away provider-specific APIs, authentication schemes, and billing systems. Users can express preferences such as:

* Cost sensitivity versus latency requirements
* Fallback behavior during outages
* Geographic or regulatory constraints

Users pay for usage in $WAI while retaining transparency into how requests are routed.

## Supply — Service Providers

Service providers register AI capabilities with the protocol and publish pricing weights. Revenue is earned based on **actual demand**, measured through PoTU receipts, rather than fixed contracts.

This includes:

* Model providers (OpenAI, Anthropic, Google, etc.)
* Cloud infrastructure operators
* Specialized inference services
* Capacity holders with idle compute

## Routing — Node Operators (Router + Validator)

Node operators are responsible for:

* Forwarding AI requests to appropriate services
* Observing execution outcomes
* Participating in performance validation through PoLP

**Crucially, RouterLink couples routing and validation into a single role.** Nodes that influence traffic are also accountable for observing and validating results.

## Economic Alignment

|      Role      |     Contribution     |         Reward Mechanism         |
| :------------: | :------------------: | :------------------------------: |
|    **Users**   | Pay for AI inference | Access to multi-provider routing |
|  **Providers** |  Supply AI capacity  |    Revenue from verified usage   |
|    **Nodes**   |   Route & validate   |    Fees + performance bonuses    |
| **Delegators** |     Stake capital    |       Share of node rewards      |

All rewards are derived from protocol-generated proofs (PoTU/PoLP), not discretionary allocation.
