The Arbitrum Foundation, along with the Celestia Foundation, today announced that Celestia is the first modular data availability (DA) network to integrate into Arbitrum Orbit and the full Nitro stack. The integration offers developers the option to publish data to Abritrum One, Abritrum Nova, and now, Celestia. Arbitrum Orbit lets developers create their own dedicated Orbit chain that settles to one of Arbitrum’s Layer 2 (L2) chains: Arbitrum One, Arbitrum Nova, Arbitrum Goerli, or Arbitrum Sepolia, creating the most advanced scaling blockchain solution on the market.
Celestia is a modular consensus and data network that securely scales with the number of users. Celestia is on track to be the first modular DA solution for Ethereum developers that scales based on Data Availability Sampling (DAS), optimized to provide the data throughput needed for millions of rollups without compromising on security for end users. Ethereum and Arbitrum developers can tap into Celestia via Blobstream, currently relaying data to Ethereum Sepolia testnet for integration with leading rollup frameworks. Blobstream can be deployed on Arbitrum L2s for integration with Arbitrum Orbit and the Nitro tech stack.
“We are excited to welcome Celestia to the Arbitrum ecosystem and making their technology available for Orbit chains,” said Elias Abi Daoud, Community Lead at Arbitrum Foundation. “With the permissionless nature of the Orbit tech stack, we’re excited to see the broadening range of supported data availability options beyond Ethereum, and we look forward to growing the diverse network of developers taking advantage of this technology.”
“Our mission is to make deploying a blockchain as easy as deploying a smart contract,” said Mustafa Al-Bassam, Director of the Celestia Foundation and co-Founder of Celestia. “This integration brings Celestia’s modular DA layer to Arbitrum’s vibrant ecosystem, enabling developers to launch high-throughput, customizable chains using Orbit and Stylus.”
Integration of Celestia is the first external contribution to the Arbitrum Orbit protocol layer, thus providing an additional option for developers selecting a data availability layer alongside Arbitrum AnyTrust. Celestia is in the final stages of its Mainnet Beta launch sequence. In the coming weeks, Orbit developers will be able to integrate with Celestia with full Nitro integration.
About The Arbitrum Foundation
The Arbitrum Foundation, founded in March 2023, supports and grows the Arbitrum network and its community with secure scaling solutions for Ethereum. Arbitrum One—a leading Ethereum Layer-2 scaling solution initially developed by Offchain Labs—offers ultra-fast, low-cost transactions with security derived from Ethereum through Optimistic Rollup technology. Launched in August 2021, the Arbitrum One mainnet beta is EVM-compatible to the bytecode level and has 54%+ TVL in the L2 segment. 2000+ DeFi and NFT projects are live in the ecosystem to date. In August 2022, Arbitrum One upgraded to Nitro tech stack, enabling fraud proofs over the core engine of Geth compiled to WASM.
