6. Proof-Based Routing: PoTU and PoLP
RouterLink is built on a proof-based routing system that connects execution, performance evaluation, and economic settlement into a single verifiable flow.
PoTU and PoLP Mechanism
Request Lifecycle
Proof of Token Usage (PoTU)
PoTU measures AI usage at the protocol level. Each routed request generates a signed usage receipt recording:
Request and routing path
Service endpoint involved
Usage metrics relevant to billing
PoTU ensures: Usage cannot be fabricated, settlement is verifiable, disputes resolved against signed receipts.
Proof of LLM Performance (PoLP)
PoLP measures how well services perform through cross-node observation, not unilateral reporting. Metrics include latency, availability, stability, and error patterns.No single node defines performance. Aggregated observations determine routing priority and reward weighting.
