Токеномика Bittensor (TAO)

Bittensor (TAO) utilizes a decentralized economic model designed to incentivize the production and distribution of machine intelligence. Its tokenomics are heavily inspired by Bitcoin, featuring a capped supply, a fair launch, and a programmatic halving schedule.

Issuance Mechanism

The issuance of TAO tokens follows a predictable, decreasing rate to manage inflation and ensure long-term scarcity.

• Maximum Supply: The total supply of TAO is capped at 21,000,000 tokens.
• Block Emissions: One TAO token is issued every block, which occurs approximately every 12 seconds. This results in the creation of 7,200 TAO per day.
• Halving Cycle: Similar to Bitcoin, Bittensor employs a halving mechanism. However, instead of occurring at fixed block numbers, halving events are triggered by total token issuance. A halving occurs once 50% of the remaining supply has been issued (approximately every four years).
• Token Recycling: Bittensor features a unique "recycling" mechanism where tokens paid for registration fees (miners and validators) and transaction fees are burned back into the unissued supply. This process effectively postpones the halving date by reducing the net circulating supply.

Allocation Mechanism

The distribution of daily emissions is managed through a layered architecture involving the "Root Network" and individual "Subnets."

Root Network (Subnet 0)

The Root Network acts as the governance hub for emissions. The top 64 validators by stake vote to determine what percentage of the daily 7,200 TAO emissions is allocated to each of the active subnets.

Subnet Allocation

Once emissions are directed to a specific subnet, they are typically distributed according to the following fixed proportions:

Usage and Incentive Mechanism

The TAO token serves as the primary incentive for all participants within the ecosystem, facilitating a "work token" model.

• Miners: Earn TAO by performing computational tasks (e.g., generating text, images, or processing data) defined by the specific subnet's protocol. Their rewards are determined by their performance ranking relative to other miners.
• Validators: Earn TAO by evaluating the work produced by miners. They use the Yuma Consensus (YC) mechanism to reach an agreement on miner rankings. Validators with higher "Vtrust" (trust scores) receive increased rewards.
• Subnet Owners: Receive a fixed 18% of emissions for designing the incentive mechanisms and maintaining the subnet infrastructure.
• Delegators: TAO holders can delegate their tokens to validators to earn a share of the validator's rewards. Validators typically charge a "take rate" or commission (often between 9% and 18%) on these earnings.

Locking and Unlocking Mechanism

Bittensor does not have traditional venture capital vesting schedules because it was launched as a "fair launch" project with no pre-mine or ICO.

• Staking (Locking): To participate as a validator or to access the network's intelligence, users must stake TAO. Staking effectively locks the tokens to secure the network and determine voting power in the Yuma Consensus. As of late 2024, approximately 80.95% of the total circulating supply was staked.
• Unlocking Time: While the protocol allows for unstaking, the "unlocking" of the total 21 million supply is governed by the daily emission schedule. The final tokens are projected to be issued by approximately 2075, at which point the network is expected to transition to a model supported by direct payments for services rather than inflationary rewards.

Future Developments: Dynamic TAO

A significant proposal known as Dynamic TAO (BIT001) aims to move away from manual emission voting. Under this proposed system, each subnet would have its own token paired with TAO in a Uniswap V2-style liquidity pool. Emissions would then be automatically allocated to subnets based on the market price of their respective subnet tokens, allowing market demand to dictate capital allocation.
