Celestia (TIA) is a modular blockchain network that separates consensus and data availability from transaction execution. Instead of processing transactions itself, Celestia acts as a base layer that ensures data is available and verifiable for other blockchains. This approach allows developers to launch their own chains or rollups without building full infrastructure from scratch, while still inheriting security from Celestia’s validator network.
At the core of Celestia’s design is data availability sampling, a technology that lets nodes verify large amounts of data without downloading the entire dataset. This reduces hardware requirements and allows the network to scale efficiently without compromising decentralization. Unlike traditional monolithic blockchains, Celestia does not impose execution rules, giving developers full control over how their applications operate.
The TIA token is used for staking, securing the network, paying for data availability, and participating in governance. Celestia is not designed as a payment network but as infrastructure for rollups and Layer 2 solutions, making it a key component in scaling blockchain ecosystems and enabling new types of decentralized applications.
