Токеномика Bittensor (TAO)

Bittensor (TAO) is a decentralized machine intelligence protocol that utilizes a unique economic model to incentivize the production of digital commodities, such as machine learning models, storage, and compute power. The network's native token, TAO, serves as the core utility and incentive mechanism for all participants.

Issuance Mechanism

Bittensor’s issuance model is heavily inspired by Bitcoin, featuring a fair launch with no pre-mined tokens or Initial Coin Offerings (ICOs).

• Maximum Supply: The total supply is capped at 21,000,000 TAO.
• Daily Emission: Currently, the network issues 7,200 TAO per day.
• Block Reward: One TAO is issued every block, with a block time of approximately 12 seconds.
• Halving Cycle: Bittensor employs a halving mechanism where the issuance rate is reduced by 50% once half of the remaining supply has been issued. This occurs approximately every four years.
• Recycling Feature: A unique aspect of Bittensor is the "recycling" of tokens. TAO paid for registration fees or transaction costs is removed from the circulating supply and returned to the unissued supply. This process effectively postpones halving events, as the halving is triggered by total issuance rather than block height.

Allocation Mechanism

The distribution of newly issued TAO is determined by the Root Network (Subnet 0) and the Yuma Consensus (YC) mechanism.

Within the validator's 41% share, a further breakdown occurs due to delegation:

• Delegators: Receive approximately 82% of the validator's share (the dividends).
• Validators: Retain approximately 18% as a "take rate" or commission for their operational services.

Usage and Incentive Mechanism

TAO is a utility token that powers the internal economy of the Bittensor ecosystem through several key functions:

• Incentivizing Intelligence: Miners are rewarded for contributing high-quality machine learning models or other digital commodities. The Yuma Consensus mechanism ensures that rewards are distributed based on the subjective evaluation of validators.
• Access to Resources: To access the intelligence produced by the network, users or developers must hold or stake TAO. Validators with larger stakes receive priority when querying miners for responses.
• Governance: TAO holders can participate in the network's trajectory by delegating their tokens to validators. These validators (specifically the top 64 by stake) vote on the proportion of network emissions directed to each subnet.
• Payment of Fees: TAO is used to pay for network operations, including:
  • Subnet Creation: A minimum fee of 100 TAO (which can increase based on demand).
  • Registration: Miners and validators must pay a variable registration fee to join a subnet.
  • Transactions: A standard fee of 0.000000145 TAO (145 RAO) per transaction.

Locking Mechanism and Unlocking Time

The primary locking mechanism in Bittensor is Staking and Delegation.

• Staking: Validators must stake TAO to participate in consensus and earn rewards. As of late 2024, approximately 80.95% of the total circulating supply was staked across all validators.
• Delegation: Token holders can "lock" their tokens by delegating them to a validator's hotkey. This allows holders to earn a portion of the validator's rewards (dividends) without running their own hardware.
• Locking for Registration: Miners and validators effectively "lock" or "recycle" TAO when paying registration fees to secure a slot in a competitive subnet.
• Unlocking Time: While the provided data does not specify a mandatory "unbonding period" or a fixed number of days for unlocking staked TAO, it notes that rewards are paid "instantly or near-instantly" based on rank. The "Dynamic TAO" proposal (BIT001) suggests future mechanisms where staking in subnet-specific pools (similar to AMMs) would influence token liquidity and pricing.
