The Evolution of Bittensor: From Legacy to dTAO

Bittensor’s decentralized network incentivizes the creation of machine intelligence through a dynamic subnet ecosystem. Historically, TAO holders delegated tokens to validators, who directed emissions to subnets in exchange for commissions. Subnet rewards were distributed among owners, miners, and validators, with TAO emissions tied to staking dynamics.
The dTAO upgrade reimagines this model. Each subnet now operates with its own liquidity pool and alpha tokens. Network-wide, 1 TAO is emitted per block, while subnets generate 2 alpha tokens per block. These alpha tokens split into two streams:
- alpha_in (0–1 alpha per block), which flows into the subnet’s liquidity pool, scaling with the pool’s TAO reserves.
- alpha_out (1 alpha per block), distributed as rewards (18% to subnet owners, 41% each to miners and validators).
Subnet success now hinges on retaining TAO in a subnet's liquidity pool. Yet subnet owners face a dilemma: monetizing alpha_out requires selling these tokens for TAO, which depletes the pool and stifles future rewards.
