Subnet Creation and Incentive Mechanisms

A subnet is a specialized market within Bittensor where miners produce a targeted digital commodity and validators evaluate that work. Subnet creators define the incentive mechanism—the explicit rules and evaluation setup that guide validators when scoring miners.

What subnet creators do

• Specify the work to be produced (e.g., model inference, retrieval, storage, compute).
• Define the evaluation process and metrics that validators should apply.
• Provide datasets, prompts, or protocols for validators to use when testing miners.
• Publish transparent rules so miners can optimize and validators can reproduce evaluations.

Validators and miners within the subnet

• Validators: Run the mechanism, evaluate miners, and submit weights that represent relative performance.
• Miners: Register to the subnet, produce outputs, and compete to maximize validator scores.

From mechanism to rewards

• Validator-submitted weights are aggregated (e.g., via Yuma Consensus) to derive final allocations.
• Emissions of TAO are distributed to miners and validators per the aggregated outcome.
• Stakers delegating to validators share in validator dividends.

Designing good mechanisms

• Measurable: Metrics are objective or reproducible.
• Robust: Hard to game; resilient to adversarial behavior.
• Transparent: Rules and datasets are disclosed to enable fair participation.
• Timely: Evaluations can be run regularly so incentives stay current.

Lifecycle (high level)

1. Draft mechanism and publish specification (tasks, metrics, scoring).
2. Stand up validator reference implementations and datasets.
3. Launch the subnet; miners register and start competing.
4. Iterate on the mechanism as needed to improve signal quality and anti-gaming.
