Bittensor’s v440 emission gate

Runtime 440 routes the TAO-side emission pool through a demand gate. Subnets above the live bar keep most of their weight; the network compresses weaker demand and reallocates the difference.

How the Bittensor emission gate works

Runtime 440 routes the TAO-side emission pool through a demand gate. Subnets above the live bar keep most of their weight; the network compresses weaker demand and reallocates the difference.

This snapshot uses Finney block 8728105, runtime spec 440, captured July 29, 2026. The live q was 75%, h was 3, and theta was 0.916%.

Measure smoothed demand: Start with each eligible subnet's moving price. This is an EMA, so a single trade cannot rewrite the full allocation at once.
Account for miner burn: Multiply the moving-price weight by one minus the subnet's miner-burn fraction, then normalize the demand shares again.
Compare each share with the bar: The live bar is a demand-share threshold, not a fixed subnet number. At this snapshot it was 0.916% of adjusted demand.
Gate and redistribute: Shares far above the bar retain most of their weight. The gate compresses shares below it, then the network redistributes the full pool across emission-enabled subnets.

SN44 versus SN32 under the old and new rules

SN44: Score

Adjusted demand rank 6, with 4.11% of demand and 98.91% of its weight passing through the gate.

Same-block pool share: 4.57% under the old linear rule and 5.80% under runtime 440.

Daily equivalent at this block: 39.77 injected TAO, 168.92 TAO for chain buys, and 208.69 TAO in total emission. These figures multiply the block snapshot by 7,200 blocks; they are not rolling 24-hour totals.

SN32: ItsAI

Adjusted demand rank 54, with 0.39% of demand and 6.94% of its weight passing through the gate.

Same-block pool share: 0.43% under the old linear rule and 0.04% under runtime 440.

Daily equivalent at this block: 1.37 injected TAO, 0.00 TAO for chain buys, and 1.37 TAO in total emission. These figures multiply the block snapshot by 7,200 blocks; they are not rolling 24-hour totals.
