Walkthrough of August Incentive Reforms on Bittensor

Bittensor is running two major protocol changes back to back, and the pair fundamentally rewrites how emissions flow across the network.

Trend Setter Capital walked through both, unpacking the Emission Gate and Root Reborn alongside the specific math that decides which subnets earn what.

The changes touch every $TAO holder, whether they are staked directly into subnets or parked comfortably in root.

Strongest Points From the Explainer

The video worked through the root problem first, then broke down the four-step math behind the new emission gate.

1. Half the $TAO supply sits in root today: Roughly 50% of circulating $TAO is parked in root, which means half the network has no opinion on which subnets matter. That is exactly what dynamic $TAO was designed to move past.

2. Root’s 7% APY is funded by automatic subnet sell pressure: Validators staked across all 128 subnets automatically sell part of their alpha rewards to pay root stakers. Non-opinionated capital effectively forces the subnets doing real work to fund root’s yield.

3. Root Reborn turns validators into portfolio managers: Instead of paying root automatically, validators now curate weighted subnet baskets. Real research replaces default staking. Weak picks get punished across the validator’s whole book.

4. Root stakers now hold their validator’s basket rather than root itself: If a validator picks SN50, SN60, SN70, and SN80 at equal weights, root stakers hold that composition. Yield requires a manual claim, and returns depend on how the picks perform against $TAO.

5. The Emission Gate replaces gameable EMA-price emissions with a four-step allocation: The old rule paid subnets proportional to their exponential moving average price, which made emissions vulnerable to hype-driven pumps. The new gate layers in smoothing, penalties, and a demand threshold that cannot be spoofed cheaply.

6. Step one (demand share): Each subnet’s EMA price is divided by the sum of all EMA prices. Chutes (SN64) currently sits at 6.43%.

7. Step two (miner burn penalty): Subnets burning miner emissions get their demand share proportionally cut. Around 35% of subnets currently burn 100% of miner emissions. That leaves roughly 30% of the $TAO pot to redistribute across non-burning subnets, which lifts Chutes from 6.43% to 9.2%.

8. Step three (the bar): The chain ranks subnets by descending demand share and walks down until cumulative demand hits Q, currently set to 75%. Whoever sits at the bar keeps only half. Enigma (SN63) currently occupies that seat with 0.91% demand share, keeping 52%.

9. Step four (keep score): Every subnet gets a smoothed keep score based on ranking. Chutes lands at 99.9%, and Ditto at rank 24 keeps 68%. Tail-end subnets keep only 1-5%, meaning the chain effectively dilutes them regardless of what their EMA price implies.

10. A final 1.37x multiplier boosts the survivors: The chain still has to emit all 3,600 $TAO per day, so whatever share got lost in the tail gets redistributed proportionally across surviving subnets. Chutes ends at 12.66% final emission share, translating to roughly 460 $TAO and 460 $SN64 per day flowing into its liquidity pool.

Bittensor Is Itself a Subnet

Bittensor can be viewed as a subnet itself, with the Opentensor Foundation acting as its subnet owner, making Root Reborn and the Emission Gate two parts of the same incentive redesign.

The core team’s challenge is to algorithmically determine which subnet owners deserve a share of the fixed 21 million $TAO supply without relying on centralized decision-making.

Root Reborn stops passive Root staking from funding sell pressure, while the Emission Gate prevents subnet owners from collecting emissions without delivering meaningful value.

Together, these changes reinforce a single principle: reward subnets that create genuine demand and utility while starving those that exist only to farm emissions, making a deep understanding of both upgrades essential for serious TAO holders.
