Bittensor（TAO）代币经济学

Bittensor’s token economics are designed to incentivize decentralized AI and digital commodity markets through a unique, Bitcoin-inspired issuance and allocation model, with additional mechanisms for usage, incentives, and governance. Below is a comprehensive breakdown of the TAO token’s economics, including issuance, allocation, usage, incentives, locking, and unlocking mechanisms.

Issuance Mechanism

• Fair Launch: No pre-mine, ICO, or team allocation. All TAO tokens are mined by network participants (miners and validators).
• Fixed Supply & Halvening: The maximum supply is capped at 21 million TAO. New tokens are issued at a fixed rate of 1 TAO per block (every 12 seconds), equating to 7,200 TAO per day.
• Halvening Schedule: The issuance rate halves each time 50% of the remaining supply is mined, not at fixed block intervals. This is similar to Bitcoin but is triggered by supply milestones, not block numbers. The halving schedule is as follows:

• Recycling Mechanism: TAO tokens used for transaction fees, miner/validator registration, and subnet creation are “recycled” (burned and returned to the unissued supply), which can delay halving events and reduce effective inflation.

Allocation Mechanism

• All tokens are distributed to network participants (miners and validators) via block rewards. There is no team, foundation, or investor allocation.
• Subnet Emission Distribution: After emissions are allocated to subnets by the root network (SN 0), each subnet distributes its share as follows:

• Validator Delegation: Of the validator share (41%), 82% is distributed to delegators (those who stake TAO with validators), and 18% remains with the validators themselves.

Usage and Incentive Mechanism

• Work Token Model: TAO must be staked by validators to access network intelligence and develop applications. The more TAO staked, the more work a validator can perform and the more rewards they can earn.
• Incentive Feedback Loop: Subnet owners define incentive mechanisms for miners, who compete to maximize rewards. Validators rank miners, and the Yuma Consensus mechanism determines reward distribution based on performance and stake.
• Token Utility:
  • Payment for subnet creation (minimum 100 TAO, variable by demand)
  • Transaction fees (recycled)
  • Staking for validator and miner registration
  • Delegation to validators for reward sharing
  • Access to AI services and APIs built on Bittensor
• Dynamic Emission Proposal: A proposed (but not yet implemented) “Dynamic TAO” mechanism would allow TAO holders to vote on emission allocations to subnets based on their perceived value to the ecosystem.

Locking and Unlocking Mechanism

• No explicit vesting or lockup for team or investors: All tokens are unlocked through mining/validation.
• Staking: Validators and delegators must lock TAO to participate in consensus and earn rewards. The amount staked determines influence and reward share.
• Unlocking Schedule: All TAO is unlocked linearly through daily block rewards, with halvening events reducing the daily issuance over time. The final TAO will be unlocked by 2075, after which no new tokens will be issued.

Additional Notes

• Governance: Proposals are made by a Triumvirate of Opentensor Foundation employees, with a bicameral system intended to transition to greater community control over time.
• No Claims or Rights: TAO does not confer legal rights, profit sharing, or claims on the foundation.
• Network Security: Subtensor, the underlying blockchain, uses Proof-of-Authority nodes managed by the foundation, but anyone can run public nodes for synchronization.

Implications and Nuances

• Decentralized AI Incentives: The model is designed to continuously reward the best-performing AI models and digital commodities, driving innovation and competition.
• No Pre-mine/Team Allocation: Ensures a fair launch and ongoing decentralization, but also means network security and development rely on community and foundation incentives.
• Dynamic Emissions: The proposed dynamic allocation could further optimize resource distribution as the network matures.
• Scalability and Governance: Manual emission allocation by top validators may become a bottleneck as the number of subnets grows, highlighting the need for more automated or community-driven governance.

Bittensor’s token economics are a sophisticated blend of Bitcoin-inspired issuance, delegated proof-of-stake, and dynamic, performance-based incentives, all tailored to foster a decentralized, scalable, and competitive AI ecosystem.
