Celestia is an innovative modular blockchain network that aims to separate the "data availability" and "consensus" layers from traditional blockchains, making it easier to build other blockchains, especially roll-ups or layer-2 scaling chains.
Celestia's native token is TIA, used to pay network fees (specifically for submitting data availability blobs), participate in staking, and govern.
Celestia's mainnet officially launched on October 30, 2023, along with the TIA token generation event (TGE).
Technically, Celestia's modular blockchain architecture uses data availability and consensus as the foundational layers, while other execution layers (such as application logic and transaction execution) can be built independently. This improves scalability and reduces node operating costs compared to traditional monolithic blockchains.
TIA's initial inflation rate is approximately 8%, decreasing by approximately 10% annually until the long-term inflation rate reaches approximately 1.5%.
From a token functionality perspective, TIA primarily serves three purposes:
1. Payment for data availability services (when a roll-up submits its data to the Celestia network, TIA is required as a fee).
2. Staking for network consensus and security.
3. Governance, allowing holders to participate in protocol upgrades, parameter adjustments, etc.
The launch of Celestia provides a "data availability infrastructure" role for the emerging blockchain scaling field (especially roll-ups and Layer 2 solutions). As more chains choose external data availability layers, its ecosystem is expected to grow further.
Celestia (TIA) is a noteworthy infrastructure project and one of the more prominent attempts in the era of modular blockchains.
