A modular data-availability network that other blockchains plug into rather than a single monolithic chain — Celestia handles ordering and guaranteeing data availability for transactions, while execution happens on separate rollup or app-specific chains built using Celestia's tooling. Current self-positioning (per celestia.org) emphasizes launching custom, high-throughput chains via the Celestia stack, the same "framework other chains are built with" shape as Cosmos SDK, rather than a single implementable spec. Maintained by Celestia Labs (development) under the umbrella of the Celestia Foundation.
Origins Modular blockchain design — separating data availability (Celestia's job) from execution (handled by rollups/app-chains built on top), rather than one monolithic chain doing both.
Database Chain-specific data-availability layer; not a queryable database in the conventional sense.
Query Language JSON-RPC/gRPC node query endpoints.
Data Formats Protobuf (inherited from its Cosmos SDK/CometBFT base).
Collaborative Live Editing N/A
Rich Text Editing N/A
Mobile Support N/A directly (infrastructure-layer; chains built on top provide end-user-facing apps)
Web Support N/A directly (infrastructure-layer; chains built on top provide end-user-facing apps)
Native Apps N/A (a framework/network, not an end-user app)
Terms Free, open-source; rollups/app-chains pay data-availability fees to Celestia validators.
Funds Celestia Foundation's treasury not independently sized this pass.
Based OnBuilt on Cosmos SDK + CometBFT (this story's own separate Cosmos SDK entry) , extended with data-availability sampling (DAS) — a novel technique enabling light nodes to verify data availability without downloading full blocks.
P2P Architecture Validator gossip network (CometBFT-based) plus a light-node network that performs data-availability sampling independently.
Development Tools SDK/tooling for launching rollups and app-chains against the Celestia DA layer (positioned as the core product per current homepage framing).
Deployment Options Self-hosted validator/light-node deployment; rollups/app-chains built on top deploy independently.
Authentication & Identity Cosmos SDK-style accounts (inherited from its base stack).
Storage Model On-chain data-availability layer — data is published and its availability is guaranteed/verifiable, not stored as general-purpose application state.
Interoperability IBC-compatible (inherits from its Cosmos SDK base), plus its core purpose is serving as a shared DA layer other chains depend on.
