Tao Emission

Basics on how tao is emiitted and distributed in Bittensor.

Every block, 1 tao is emitted by the chain (until 10.5M blocks are emitted and the first halving occurs). Where do these blocks go?

The tao is divided amongst the subnets and the fraction of tao awarded to each subnet is placed into the tao_in of the Subnet Pools.


Determining the emission into each Subnet pool.

In the past, Subnet emissions were set by validators, and Yuma Consensus would aggregate the results based on validator stake and consensus. This is no longer the case.

Tao emission (also known as tao_in) on a subnet is calculated by finding the subnet price, and dividing by the total of all subnet prices.

This ensures that 1 tao is emitted every block, and distributed amongst the subnets.

Tao_in example:

If the Sum of all prices is 1.8, and the proce for a Subnet is 0.2.

tao_in will be 0.2/1.8 = .111 per block.
