Cluster Verification Test

The Cluster Verification Job is a daily test conducted to determine whether a worker (CPU or GPU) meets the necessary criteria to be part of the actual cluster. This process ensures that all participating workers maintain stability and performance standards.

1️⃣ CPU Workers

For CPU workers, the verification job primarily evaluates device stability based on the following criteria:

• The worker must remain active in the cluster for a continuous 60-minute duration without interruptions.
• If the worker disconnects or becomes unresponsive during this period, the test is marked as failed.

This ensures that only reliable CPU workers contribute to the network.

2️⃣ GPU Workers

For GPU workers, the verification job involves two critical tests:

1. VRAM Stability Test
   • This test allocates VRAM memory and applies a workload to determine the GPU's ability to handle operations under stress.
2. Cluster Uptime Test
   • The worker must stay active in the cluster for 60 minutes without any interruptions.

If a GPU worker fails either of these tests, the verification job is deemed failed.

3️⃣ Failure Consequences

Repeated failures in the verification job can result in temporary ineligibility for Block Rewards:

• If a worker fails more than 3 times within a calendar month, it becomes temporarily ineligible for Block Rewards for a period of 12 hours.
• The worker will remain ineligible unless another failure occurs, which resets the cooldown period.

This rule ensures that only stable and reliable workers continue to participate in the cluster.
