2.2 Scheduler (Consensus dispatcher)

• Service name: px-scheduler

• Tech stack: FastAPI, Async HTTPX

• Port: 7080

• Docker image: ghcr.io/privacyx-org/px-scheduler

Responsibilities

• Receives jobs from the Gateway.

• Dispatches them across a pool of miners using round-robin scheduling.

• Performs retry & health checks.

• Gathers responses and forwards them to the Validator for consensus evaluation.

Consensus workflow

1. For each incoming request (image/video), the scheduler selects 3 miners.

2. Collects probabilistic outputs from each miner.

3. Sends the results to /assess on the Validator for outlier filtering and consensus averaging.

Health management

Each miner is periodically checked via /health. Unhealthy miners are temporarily excluded from dispatch rotation.
