Celestia Unveils Blobstream Data Proof Bridge on Base Mainnet
In Brief
The Blobstream data attestation bridge introduced by Celestia is now operational on the Ethereum Layer 2 network known as Base.

Modular blockchain network Celestia Celestia has announced that its Blobstream attestation bridge is now live, starting on the Ethereum Layer 2 platform. Base This information was shared through a recent update posted on the social media platform X.
Developers are now presented with a fantastic opportunity to merge the latest Ethereum rollup framework with Blobstream, thereby enhancing the growth of different ecosystems.
Created by Succinct Labs Blobstream functions as a single-directional data attestation bridge, enabling the use of Celestia for modular data verification on Ethereum Layer 2 and beyond. Layer 3 networks It utilizes both data availability proofs and Merkle roots sourced from aggregated Celestia block data, ensuring that rollup data on the Celestia platform can be verified.
Structured on Celestia, which is powered by a CometBFT-based proof-of-stake (PoS) consensus, Blobstream conforms to the security principles foundational to the Celestia platform. However, it’s worth noting that the data attestation bridge is currently considered experimental software, so users should proceed with care and be aware of the potential risks involved in its use.
Base Layer 3 solutions empower developers to build high-capacity blockspaces effortlessly, with Celestia serving as the foundational infrastructure.
Before Celestia was launched, developers who sought to create complex on-chain applications often hit walls due to limited throughput. This scenario frequently pushed them to consider alternative Layer 1 solutions or rely on trusted but cumbersome data availability solutions to build their blockchain networks.
With Blobstream, developers can keep innovating within the existing framework while setting up tailored, high-capacity blockspaces without needing to form a committee or depend on a centralized server for data availability.
The Integration of Blobstream by Celestia Significantly Boosts Scalability for Ethereum's Layer 2 and Layer 3 Solutions.
Data availability remains a critical hurdle for scaling the Ethereum ecosystem, especially as the usage of Layer 2 solutions grows and new types of applications emerge on the blockchain.
Blobstream provides a seamless connection for Ethereum’s Layer 2 developers to integrate with Celestia, which is set to be a leading data availability layer employing data availability sampling (DAS). Acting as a modular data availability layer, Celestia offers designated blob spaces with pricing separated from gas fees and distinct from execution processes, thus enhancing data throughput. Ethereum Recently, Celestia utilized its Blobstream tool to connect its modular data availability layer to Ethereum and EthStorage. This was achieved through its proprietary proof-of-data availability algorithm, which samples data over time, making it work as a lasting storage solution for data availability BLOBs. This integration seeks to establish a comprehensive long-term data availability framework tailored specifically for Ethereum's Layer 2 and Layer 3 platforms.
