TIA（TIA）代币经济学

Celestia’s native token, TIA, is the core utility and incentive mechanism for its modular data availability (DA) network. Launched on October 31, 2023, with the Mainnet Beta, TIA facilitates network security, transaction processing, and decentralized governance.

Issuance Mechanism

Celestia employs an inflationary issuance model with no maximum supply. The initial total supply at genesis was 1,000,000,000 TIA.

• Inflation Schedule: TIA inflation started at 8.00% annually for the first year. This rate decreases by 10.00% each year until it reaches a long-term floor of 1.50%, projected to occur around October 31, 2039.
• Reward Distribution: Approximately 98.00% of inflationary emissions are distributed to reward validators and their delegators. The remaining 2.00% is directed to the Community Pool to fund ecosystem initiatives.
• Calculation Method: Annual provisions are calculated based on the total supply at the start of each year. To ensure accuracy despite variable block times, Celestia uses block timestamps rather than block height to determine issuance per block.

Allocation Mechanism

The initial 1 billion TIA supply was distributed across five primary stakeholder categories to balance early contributor rewards with long-term ecosystem growth.

Usage and Incentive Mechanism

TIA serves several critical functions within the modular ecosystem:

• Data Availability Fees: To use Celestia for data availability, rollups must submit "PayForBlobs" transactions. These fees are paid exclusively in TIA and consist of a flat fee plus a variable fee based on the size of the data blob.
• Staking and Security: Celestia uses a Delegated Proof-of-Stake (DPoS) mechanism. Users secure the network by staking TIA to validators. The active validator set is limited to the top 100 nodes by total stake (self-staked plus delegated).
• Gas Token for Rollups: Developers can choose to use TIA as a gas token for their own rollups, allowing them to launch without immediately issuing a new token.
• Governance: TIA holders can vote on Celestia Improvement Proposals (CIPs) to modify network parameters, such as the percentage of inflation directed to the Community Pool.
• Burn Mechanism: While there is no buyback program, TIA can be burned through governance. For example, if a proposal is rejected with a "No_with_Veto" majority, the TIA deposit associated with that proposal is burned.

Locking and Unlocking Mechanism

Celestia utilizes a combination of "cliff" unlocks and linear vesting to manage the introduction of new supply into the market.

Locking Mechanism

All tokens, whether locked or unlocked, can be staked to secure the network. However, while the principal may be locked, the staking rewards are typically unlocked upon receipt and can be moved freely, contributing to the circulating supply.

Unlocking Schedule

The unlocking process began significantly one year after the mainnet launch.

• Public Allocation: The Genesis Drop portion (7.4%) was fully liquid at launch.
• R&D & Ecosystem: 25% was unlocked at launch, with the remaining 75% unlocking continuously from Year 1 to Year 4.
• Insiders (Core Contributors & Backers): These groups generally followed a schedule where 33% unlocked at the one-year milestone (October 31, 2024). The remaining 67% unlocks linearly over subsequent periods (typically 1 to 2 additional years depending on the specific category).

Current and Future Unlocks

As of April 2026, the network continues to experience steady linear unlocks. Data indicates a consistent daily release of approximately 345,096 TIA into the circulating supply. This daily issuance represents a marginal impact of roughly 0.04% on the circulating supply per day.
