Tokenomics de TIA (TIA)

Celestia (TIA) is the native utility token of the Celestia network, a modular data availability (DA) layer. The tokenomics are designed to facilitate network security through proof-of-stake, govern the protocol, and provide a medium of exchange for data availability services.

Issuance Mechanism

TIA was launched on October 31, 2023, with an initial total supply of 1,000,000,000 tokens. The network employs an inflationary issuance model to reward participants and fund ecosystem growth.

• Initial Inflation Rate: The supply began inflating at an annual rate of 8.00%.
• Disinflationary Schedule: Starting October 31, 2024, the inflation rate decreases by 10.00% each year.
• Terminal Inflation: This reduction continues until the inflation rate reaches a floor of 1.50% annually, which is projected to occur around October 31, 2039.
• Supply Cap: There is no maximum supply for TIA. As of late 2024, the total supply had grown to approximately 1,090,000,000 TIA.

Allocation Mechanism

The initial 1 billion TIA supply at genesis was distributed across five primary categories, with a significant portion reserved for early backers and core contributors.

Usage and Incentive Mechanism

The TIA token serves several critical functions within the modular ecosystem:

Network Transaction Fees (Blobspace)

The primary utility of TIA is paying for "blobspace." Rollups and other modular networks must submit "PayForBlobs" transactions to store data on Celestia. 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) consensus mechanism.

• Validators: Users can operate one of the 100 active validator slots. While there is no hard minimum stake, only the top 100 by total stake (self-staked plus delegated) earn rewards.
• Delegators: Tokenholders can delegate TIA to a validator to secure the network and earn a pro-rata share of block rewards, minus the validator's commission.
• Reward Distribution: 98.00% of inflationary emissions go to reward validators and delegators, while 2.00% is directed to the Community Pool.

Governance

TIA holders can participate in decentralized governance by voting on Celestia Improvement Proposals (CIPs). Governance can impact network parameters, such as the percentage of inflation sent to the Community Pool or how those funds are spent. Voting power is proportional to the amount of TIA staked.

Medium of Exchange and Gas

Developers can use TIA as a gas token for their own rollups, similar to how ETH is used on Ethereum L2s. This allows new chains to launch without immediately issuing their own native token.

Locking and Unlocking Mechanism

Celestia utilizes a combination of cliff unlocks and linear vesting schedules to manage the entry of new tokens into the circulating supply.

Locking Mechanism

Tokens allocated to insiders (investors and core contributors) were subject to a one-year lock-up period following the October 31, 2023 launch. While these tokens are "locked" from transfer, they can still be staked to earn rewards. Staking rewards themselves are liquid upon receipt.

Unlocking Schedule

The first major "cliff unlock" occurred on October 31, 2024, releasing 33.00% of the tokens held by core contributors and early backers.

Current and Future Unlocks

Following the initial cliff, the network has transitioned to a steady monthly release of approximately 30,000,000 TIA. As of March 2026, the network continues to see daily linear unlocks of approximately 345,096 TIA, representing a daily impact of roughly 0.04% on the circulating supply.
