Bittensor has just reached a historic milestone. For the first time since the network was launched, the protocol has undergone its very first halving, a major event that profoundly changes the dynamics of its TAO cryptocurrency issuance. From now on, daily emissions will drop from 7,200 to 3,600 TAO, marking an important transition for the entire ecosystem. Here’s a breakdown of this key event for the ecosystem.
Half the issuance
Like Bitcoin, TAO has a maximum supply capped at 21 million units. However, unlike Bitcoin, Bittensor’s halving is not triggered by a number of blocks reached, but by the total number of TAO issued. In concrete terms, as long as the total supply does not reach certain predefined thresholds, the network continues to issue TAO at a fixed rate. Before this first halving, each block, produced every 12 seconds, generated 1 TAO, or approximately 7,200 TAO per day. Since the halving, 0.5 TAO are now generated every 12 seconds.
Another key mechanism is recycling. Some of the TAOs used to register miners and subnets are returned to the “unissued” supply. In practical terms, this process artificially reduces actual circulation and can delay the arrival of a halving.
Unissued supply
This corresponds to the portion of TAOs included in the 21 million cap but not yet created. These tokens will be issued gradually over time through block emissions.
Since February 2025, Bittensor has also introduced the concept of Dynamic TAO. Each subnet now has its own Alpha token, which can be exchanged for TAO on decentralized markets. These Alpha tokens follow the same capping and halving logic as TAO, but with one important difference: only the portion of Alpha tokens injected into liquidity pools is affected by the reduction in issuance.
What does this mean for the Bittensor ecosystem?
This first halving marks a turning point for Bittensor. The reduction in emissions has a direct effect on the liquidity available in the subnet pools. Fewer TAO issued also means less TAO and Alpha injected daily. However, not all players are affected in the same way. Alpha distributions to miners, validators, and subnet owners remain unchanged. For TAO, as with BTC, the decline in inflation is a strong signal. Fewer tokens are being created, while demand for artificial intelligence-related services continues to grow.
This new configuration favors the oldest subnets. Launched before the halving, they benefited from several months, even years, of higher liquidity injections. Conversely, new subnets will have to cope with more limited flows, making competition more demanding.
However, this change is not without risks. Scarcer liquidity may widen the gap between the best-performing subnets and less robust projects. Design flaws, lack of real-world use, or poor capital allocation will become harder to hide. The network is gradually entering a phase of efficiency rather than rapid expansion.
In addition, a reduction in TAO rewards could discourage small miners and validators, leading to a centralization of these activities by larger players.
Key takeaways
Bittensor’s first halving is not a short-term event. It is neither an immediate market signal nor a promise of an instant increase in the price of TAO. By reducing inflation while maintaining incentives, Bittensor is beginning a transition to a more mature ecosystem, where value is based more on actual usage and subnet performance. As with Bitcoin in its early days, the effects of this halving will be measured over time.
