Aptos（APT）代幣經濟學

The Aptos (APT) token economics are designed to support a high-performance Layer 1 blockchain through a combination of inflationary rewards, transaction fee burns, and a structured multi-year distribution schedule. As of early 2024, the total supply of APT has grown to approximately 1.08 billion tokens from its initial launch state.

Issuance Mechanism

Aptos utilizes an inflationary issuance model to incentivize network security and participation. The primary source of new token issuance is through staking rewards.

• Initial Inflation Rate: The network launched with a maximum annual reward rate of 7.00%.
• Disinflationary Schedule: This rate is designed to decline by 1.50% annually until it reaches a lower bound of 3.25%.
• Reward Distribution: Rewards are calculated per epoch based on the validator's staked amount and performance (specifically the ratio of successful proposals made).
• Deflationary Pressure: To counteract inflation, all transaction fees on the Aptos network are currently burned, though this mechanism can be modified through future governance proposals.

Allocation Mechanism

The initial distribution of APT was divided among four primary stakeholder groups to ensure long-term ecosystem growth and decentralization.

Usage and Incentive Mechanism

The APT token serves as the native utility and governance asset for the Aptos protocol.

• Transaction Fees: APT is required to pay for "gas" when executing transactions or smart contracts. Users specify a "Max Gas Amount" and "Gas Unit Price" to prioritize their transactions.
• Staking (Stake-for-Access): Validators must stake a minimum of 1.00 million APT to participate in consensus and earn rewards. A maximum stake of 50.00 million APT is enforced to prevent over-centralization of voting power.
• Delegation: Tokenholders with smaller balances can delegate as little as 10 APT to existing validators to earn a proportional share of block rewards, minus a commission set by the validator.
• Governance: APT stakers and delegators (with at least 10 APT) can submit and vote on Aptos Improvement Proposals (AIPs). These proposals can alter blockchain parameters, core code, or framework modules.

Locking and Unlocking Mechanism

Aptos employs a rigorous vesting and locking schedule to align the interests of early backers and contributors with the long-term health of the network.

Validator Locking

Once a validator joins the active set, their stake is locked for 30 days. This lockup period renews automatically. While a validator can request to unlock at any time, the tokens only become accessible once the current 30-day cycle expires.

Stakeholder Vesting Schedules

The major allocations for the team and investors were subject to a one-year cliff followed by a multi-year monthly release.

• Core Contributors & Investors: These groups were subject to a 12-month lockup starting from the mainnet launch in October 2022.
  • Months 13–18: 3/48 of the allocation (~11.9M APT for contributors; ~8.4M APT for investors) unlocks each month.
  • Months 19–48: 1/48 of the allocation (~4.0M APT for contributors; ~2.8M APT for investors) unlocks each month until the 4-year mark.
• Aptos Foundation: 5.00 million APT were unlocked at the Token Generation Event (TGE). The remaining balance unlocks linearly at a rate of 1/120 per month over a ten-year period.
• Community/Ecosystem: These tokens are generally liquid but are held by the Foundation and Labs to be distributed via grants and incentives over time.

Projected Unlock Events

Significant unlocking events have been noted in recent quarters, often impacting market sentiment:

• Q1 2024: Approximately $574 million worth of APT was scheduled for unlock.
• Q2 2024: Approximately $562 million worth of APT unlocked.
• Q3 2025: A projected $99.4 million worth of APT is designated for Aptos Labs and private investors.
• Long-term: The final community and foundation unlocks are projected to continue through October 2032, with monthly releases of approximately 4.54 million APT for various incentive groups.
