Celestia RPC
セレスティアの概要
Celestia is a modular blockchain network that separates data availability and consensus from execution. This design allows developers to launch their own blockchains without needing to bootstrap a validator set or compromise on scalability.
The network consists of two main components:
-
Data Availability Layer: Celestia's core function is ensuring that transaction data is accessible and verifiable by anyone. It uses Data Availability Sampling (DAS), which allows light nodes to verify data without downloading entire blocks.
-
Consensus Layer: Built on the Cosmos SDK with a modified Tendermint consensus mechanism, Celestia orders and publishes transactions while leaving execution to rollups and other chains built on top.
Celestia uses TIA as its native token for paying data availability fees, staking, and governance. The network operates on a Proof-of-Stake consensus mechanism.
Interacting with Celestia APIs
Celestia provides a JSON-RPC API through its celestia-node client. This API allows direct interaction with Celestia's Data Availability layer for operations like submitting blobs, querying headers, and managing shares.
Celestia also exposes Cosmos REST APIs and Tendermint RPC methods for querying blockchain state and consensus information. The modular design means that execution happens on rollups and other chains that use Celestia for data availability, while Celestia itself focuses on consensus and data availability functions.
The Quicknode Celestia documentation is continuously evolving as the chain undergoes upgrades and changes, so we highly recommend cross-referencing with the official Celestia documentation for the latest updates and API details.
Make Celestia API Calls
The quickest way to start building with Celestia is to create a Quicknode endpoint and send your first JSON-RPC request.
Quicknode provides managed Celestia endpoints, giving you immediate access to Celestia Mainnet and Testnet without the overhead of running infrastructure. These endpoints offer:
- 高い信頼性– ダウンタイムを最小限に抑えるよう設計された、世界中に分散したインフラストラクチャ
- Enhanced performance – optimized latency and request handling for production applications
- 統合エコシステム– Quicknode Marketplace上の専用API（アドオン）やStreamsなどの製品を通じて、追加機能を提供
