What is Celestia (TIA) ?
Celestia is a decentralized, scalable, and interoperable blockchain platform that aims to provide a secure and efficient foundation for the next generation of Web3 applications. Celestia leverages a novel consensus protocol called LazyLedger, which separates the consensus layer from the execution layer, allowing for independent and parallel development of both layers. Celestia also enables cross-chain communication and interoperability through the use of light clients and bridges. Celestia’s native token is TIA, which is used for various purposes such as staking, governance, fees, and incentives. TIA holders can participate in the network’s security and governance by delegating their tokens to validators or running their own validator nodes. TIA also serves as a medium of exchange and a store of value within the Celestia ecosystem.How Does Celestia Work?
Celestia consists of two main components: the consensus layer and the execution layer. The consensus layer is responsible for ordering and validating transactions, while the execution layer is responsible for executing and storing transactions. The consensus layer uses a proof-of-stake (PoS) mechanism, where validators stake TIA tokens to secure the network and earn rewards. The execution layer uses a data availability sampling (DAS) mechanism, where nodes store and verify data availability proofs to ensure that all transactions are accessible and retrievable. The consensus layer and the execution layer communicate through a common interface called the Celestia Block. The Celestia Block is composed of two parts: the header and the data. The header contains the metadata and the cryptographic commitments of the data, while the data contains the actual transactions and messages. The header is validated by the consensus layer, while the data is validated by the execution layer. The data can be organized into different namespaces, which represent different types of applications and protocols running on Celestia. For example, one namespace could be dedicated to a smart contract platform, while another namespace could be dedicated to a decentralized storage network. The separation of the consensus layer and the execution layer allows for several benefits, such as:Scalability
Celestia can process a large amount of data without compromising on security or decentralization, as the consensus layer only needs to validate the headers, while the execution layer can parallelize the validation of the data.Interoperability
Celestia can support any kind of application or protocol that can be encoded into data, as the execution layer can interpret and execute the data according to the rules of the corresponding namespace. Celestia can also communicate with other blockchains through the use of light clients and bridges, which can verify the headers and the data of the Celestia Block.Flexibility
Celestia can accommodate different kinds of applications and protocols without requiring hard forks or coordination, as the execution layer can evolve and innovate independently from the consensus layer. Celestia can also support multiple execution layers, each with its own logic and state, as long as they adhere to the common interface of the Celestia Block.What is TIA ?
TIA is the native token of the Celestia network, which serves various functions such as:Staking
TIA holders can stake their tokens to become validators or delegate their tokens to existing validators, who are responsible for producing and validating blocks on the consensus layer. Staking TIA tokens helps secure the network and earn rewards in the form of inflationary and transaction fees.Governance
TIA holders can participate in the governance of the network by voting on proposals and parameters that affect the consensus layer and the execution layer. Governance decisions are made through a decentralized and transparent process, where proposals are submitted, discussed, and voted on by the community.Fees
TIA is used to pay for the fees associated with the data storage and retrieval on the execution layer. Fees are determined by the supply and demand of the data, as well as the bandwidth and storage capacity of the network. Fees are paid to the validators and the data availability samplers, who provide the data availability service to the network.Incentives
TIA is used to incentivize various actors and behaviors that contribute to the growth and development of the network. For example, TIA can be used to reward developers, validators, data availability samplers, bridge operators, and other participants who provide useful services and applications to the network.
