What dTAO changed on Bittensor
Under dTAO a stake is a position in one subnet's pool, bought with τ and priced in it — not a share of the whole network.

Staking became buying
dTAO — dynamic TAO — is the network's move to one token per subnet. Staking to a subnet now means putting τ into that subnet's pool and taking its α out; unstaking is the reverse trade. The stake and unstake calls are the trades themselves; there is no exchange in between.
So a stake is a position with a price. Its value in τ moves with the pool, and two people who staked the same τ on different subnets hold different things.
One pool per subnet
Each subnet holds a constant-product pool of τ and α. The α price is the ratio of the two reserves; every buy, sell and block of emission moves it. Beside that spot price the chain keeps its own moving average for its decisions about the subnet.
Because the pool is the market, its depth decides how far an order moves the price. There is no order book, only reserves.
What stayed outside the markets
Root (SN0) is the exception: staking τ there is one-to-one at any size, with no pool and no price. Root stakers are paid a share of each subnet's validator emission instead of holding its α.
Some figures from before dTAO are still stored on chain but no longer maintained by the runtime. Taosis does not publish those; its validators directory computes an APR from the dividends the chain actually paid instead.
Where this shows on Taosis
The screener lists every subnet's α price, pool depth and emission share side by side — the figures that differ between subnets under dTAO. A subnet page shows the pool's reserves and the α staked out of it.
The swap form signs the chain's own stake and unstake calls with a price limit, and a wallet's account page lists its α by subnet rather than one stake total.

What a subnet is
A subnet is an independent market for one kind of work, with its own token, its own miners and its own price.
How the α price works
It is a ratio between two chain values, not an order book — which is why the price can move with no trade at all.
Root (SN0)
Root is where τ is staked without buying anything: one-to-one, no pool, no price — and a cut of every subnet's validator emission.
