Staking, governance, & supply ​

Proof-of-stake on Celestia ​

Celestia is a proof-of-stake blockchain based on CometBFT and the Cosmos SDK. Celestia supports in-protocol delegation and will start with an initial validator set of 100.

Staking TIA as a validator or delegator enables you to earn staking rewards from the network. Validators charge a fee to delegators which gives them a percentage of staking rewards.

Inflation ​

TIA inflation starts at 8% annually and decreases by 10% every year until it reaches the long term issuance rate of 1.5%. Exact annual inflation rates can be found in the diagram below.

The annual provisions for inflation are calculated based on the total supply of TIA at the beginning of each year. To calculate how many TIA to issue per block, Celestia uses the block timestamp rather than the block height since the time between blocks can vary and cause actual issuance to be higher than the target.

Decentralised governance ​

Network parameters ​

TIA holders (not just stakers) can propose and vote on governance proposals to change a subset of network parameters. To learn more, see a complete list of both the changeable and non-changeable parameters and their values. Additionally, learn how to submit and vote on governance proposals.

Community pool ​

Starting at genesis, Celestia’s community pool receives 2% of all Celestia block rewards. TIA stakers may vote to fund ecosystem initiatives as in many other Cosmos SDK chains.

Learn how to submit a governance proposal to spend community pool funds.

TIA allocation at genesis ​

Celestia will have a total supply of 1,000,000,000 TIA at genesis, split across five categories described in the chart and table below.

Unlocks ​

Celestia’s 1 billion TIA supply at genesis will be subject to several different unlock schedules. All tokens, locked or unlocked, may be staked, but staking rewards are unlocked upon receipt and will add to the circulating supply.

Circulating supply is defined as the amount of TIA tokens in general circulation without onchain transfer restrictions.

Available supply is defined as the amount of TIA tokens that are either part of the circulating supply or are unlocked but subject to some form of governance to determine when the tokens are allocated. This includes the unlocked portion of the R&D & Ecosystem tokens and the tokens set aside for future initiatives.

The definitions for circulating and available supply were adapted from Optimism’s definitions.

Unlock schedule by category is described in the table below.
