Starknet developers plan to use “Blobstream,” a key component of the Celestia ecosystem. Blobstream acts as a data availability (DA) layer, safely storing large amounts of data off-chain while providing verifiable evidence of its existence.
This collaboration will enable the use of Celestia in Starknet’s off-chain scaling solution to minimize transaction costs. This includes Starknet developers porting Celestia Blobstream to Cairo, the native programming language of Starknet, to support Layer 3 appchain development. This layer 3 of Starknet is currently in the development phase.
“Using Celestia as a modular DA to anchor a high-throughput appchain on Starknet is a game-changing combination,” said Starknet.
Data availability from Celestia
Celestia is the first project to implement “data availability sampling”, allowing validators in the extended network to sample a significant portion of the data for availability verification, improving efficiency and throughput compared to full data verification.
Layer 2 projects such as Manta Pacific, Aevo, and ZKFair have already used Celestia DA to develop Validium, a scaling solution that combines zero-knowledge proofs and data availability. Polygon and Arbitrum have also integrated Celestia into their layer 2 development kits.
Now, Starknet aims to use Celestia to build a layer 3 chain within the Starknet ecosystem rather than layer 2.
Previously, Starknet was in discussions with Celestia’s competitor Avail about integrating a data availability solution for the Starknet app chain using Madara, a custom sequencer.
