Dynamic TAO
Dynamic TAO is a planned evolution of the integrated tokenomic and governance model that underlies the Bittensor network. It represents a significant step in Bittensor's trajectory toward more thorough decentralization.
See: Conceptual guide to Dynamic TAO
Dynamic TAO is now live on Bittensor testnet!
Testnet tokens do not have any value.
What to expect with Dynamic TAO
Most operations will remain unchanged, including the main workflows for miners (e.g., registering on subnets) and validators (e.g., setting weights on miners).
Simply update the Bittensor SDK and/or btcli, and you will be prepared to work with the Dynamic TAO-enabled Bittensor test network.
The migration to Dynamic TAO includes breaking changes. Older versions of the SDK and btcli are not compatible with Dynamic TAO. If a participant on your subnet does not upgrade their tooling, they will fall out of consensus.
The changes to btcli and the Bittensor SDK are not backwards compatible.
Using Dynamic TAO
To update to the Dynamic TAO-enabled versions of the tooling, run:
# update the SDK to the most recent dTao enabled release candidate
pip install bittensor==8.5.1rc6
# update BTCLI to the most recent dTao enabled release candidate
pip install bittensor-cli==8.2.0rc10
The changes to btcli and the Bittensor SDK are not backwards compatible.
The migration to Dynamic TAO includes breaking changes. Older versions of the SDK and btcli are not compatible with Dynamic TAO. If a participant on your subnet does not upgrade their tooling, they will fall out of consensus.

Subnet tokens/liquidity pools
After upgrading, the most visible difference is the addition of one new token per subnet in the bittensor network.
Run btcli subnet list to view information about the subnets and their currency reserves:
For example:

Gradual impact on consensus dynamics
The rollout of Dynamic TAO is calculated to have a gradual impact. When Dynamic TAO is first released, the weight of all validators (in terms of stake) will remain unchanged, because a biasing variable known as TAO weight, which controls the relative weight of TAO and alpha currencies, will heavily favor TAO—which currently has 100% weight since alpha currencies don't exist. Over time (an estimated 100 days), this TAO Weight will shift to favor alpha currencies over TAO.
