Tao Emission

Basics on how tao is emitted and distributed in Bittensor.

Every block, 0.5 tao is emitted by the chain (the first Halving was in December 2025). Where do these tokens go?


The tao is divided amongst the subnets based on emission. And, then, depending on the alpha price, some is injected into the liquidity pool, and some is used as a chain buy to purchase alpha (that is then recycled).


How emission is determined

Net tao flow is used to determine emission. This is a new parameter being introduced in May 2026 (tao flow was introduced in early 2026). It now has its own page Tao Flow

The tao flow is normalized, and the tao emitted to each subnet subnet is based on the normalized net flow flow.

Emitted tao has 2 destinations:

  • tao injected
  • chain buy

Tao injected

This is the primary feature of tao emission. Tao from the chain is injected into the subnet's liquidity pool. An equal amount of alpha is minted and created at the same time (in order to keep the liquidity pool and the price balanced.
