Key takeaways

Celestia launched its mainnet and TIA in October 2023.
TIA pays data fees, secures the network, and carries governance votes.
Light nodes sample random data chunks to detect withholding.
Slashing can cut staked TIA for validators and delegators.

Short answer

The main risks of using Celestia are data withholding, slashing penalties against validators and delegators, sampling assumptions, and unsettled US rules for TIA, staking rewards, and airdrops.

Celestia is a modular data availability network. It lets rollups and other chains publish transaction data for others to check. TIA is the network's token, used for data fees, staking, and governance.

What are the main risks?

Celestia combines data availability with staking and a token. That mix creates risks for rollups and TIA holders.

Celestia risks at a glance
Risk	What can go wrong
Data withholding	Rollups cannot reconstruct data and may stall.
Slashing	Validators lose staked TIA; delegators can lose part of their stake.
Sampling assumptions	Light nodes may miss withheld data if assumptions fail.
Regulatory uncertainty	US rules for TIA, staking rewards, and airdrops are not settled.

How does data withholding work?

Data withholding happens when a block producer publishes a header but not all the transaction data. Celestia's light nodes use random data availability sampling to detect this. Each node asks for small random pieces of a block. If enough samples return, the node accepts the data as available.

The check is probabilistic. It works only if enough light nodes sample and the network's assumptions hold.

Who created Celestia and when?

Celestia Labs created Celestia, and the network's mainnet launched in October 2023. The project grew from research on modular blockchains, where consensus, data availability, and execution are separate layers. Celestia handles consensus and data availability.

What is TIA used for and how does it differ?

TIA is the native token of Celestia. It is not a gas-only token that just pays for computation. It pays for data fees, secures the network through staking, and gives holders governance votes.

Data fees: rollups pay TIA to publish data to Celestia.
Staking: validators and delegators lock TIA to help secure consensus.
Governance: holders vote on protocol changes such as upgrades and parameters.

Frequently asked questions

They can stall. A rollup needs the transaction data to rebuild its state and process withdrawals, so withheld data can leave users unable to sync or exit until the data appears or a fallback is used.

Celestia is a layer 1 network for consensus and data availability. It is not a layer 2 rollup; rollups can use it as a base layer for data.

No, the core Celestia protocol does not execute general smart contracts. Execution happens on rollups or other chains that post their data to Celestia.
