Tokenomics & Utility

What SN120 represents

SN120 is Subnet 120’s alpha token. It serves three roles:

1. Stake unit: Users “stake” to the subnet by swapping TAO into SN120 via the subnet’s built‑in AMM pool. This signals support and helps the subnet win a larger share of network emissions.
2. Reward flow: Newly created alpha is distributed to miners, validators (and their stakers), and the subnet owner, aligning participants around measurable progress.
3. Weight and participation: Validators’ influence and staking returns depend on both root TAO and subnet alpha holdings, with protocol parameters gradually increasing the importance of alpha over time. (docs.bittensor.com)

Emission mechanics in plain language

• Injection: Each block, the network adds TAO and alpha into the subnet’s reserves, sized in proportion to the subnet’s price vs. others. Alpha injected into the pool is calibrated so that adding liquidity doesn’t change the token’s price.
• Extraction: At regular intervals, accumulated alpha is paid out to miners, validators/stakers, and the subnet owner per the 41/41/18 split. Because more alpha than TAO enters circulation over time, alpha increasingly matters for validator weight and rewards. (docs.bittensor.com)

Unlike some tokens with a hard-coded maximum supply, Bittensor subnets emit alpha dynamically. The protocol can create up to two alpha tokens per block per subnet—one stream for the pool and one for participants—scaled by formulas that keep the economy balanced. This is why supply is best understood through the emission schedule and reserve ratios rather than a fixed cap. (learnbittensor.org)

What you can do with SN120

• Hold and stake SN120 to a validator to earn a share of subnet rewards.
• Provide economic support to the RL ecosystem that affine coordinates.
• Use SN120 positions as a signal or weighting mechanism inside the broader Bittensor economy (for example, validator strategies that combine root TAO with subnet alphas). (docs.bittensor.com)
