Subnet Owner
An individual or team that creates and manages a specialized task group (called "subnet") within Bittensor, defining the incentive mechanism and earning 18% of the subnet's ALPHA emissions.
Subnet owners are the creators and operators of subnets. They design what specific task their subnet solves (language translation, image generation, data indexing, or any other computational task). They define the rules for how miners and validators work together, including the incentive mechanism that determines how miners get scored and rewarded.
Think of subnet owners as project leads. They are responsible for making their subnet attractive to participants by clearly defining the work, maintaining the scoring system, and providing documentation so miners and validators understand the subnet's goals and requirements.
To create a subnet, the owner must pay with TAO tokens as a non-reversible cost. This cost is dynamic, and it increases when subnets are being created frequently and decreases over time when creation slows down, with a minimum cost of 1 TAO. The minimum cost in TAO gets injected into the subnet's pool, providing initial liquidity.
SUBNET COST DECAY
The subnet cost decreases over a reduction interval of approximately 16 days (115,200 blocks). If no new subnets are created, the cost gradually falls back toward the minimum.
Subnet owners receive 18% of their subnet's ALPHA emissions each block . This cut is deducted from the ALPHA emissions before the remaining 82% is distributed to validators (as dividends) and miners (as incentives).
The owner cut is received as staked ALPHA on the subnet, not as TAO. This aligns the owner's financial interest with the subnet's long-term health, because if the subnet performs well and attracts more TAO, the ALPHA becomes worth more.
