On June 11th, the modular blockchain network Celestia announced on the X platform that Blobstream has been launched on the Ethereum mainnet. Developed by Succinct Labs, Blobstream streams the promise of Celestia data roots to the Ethereum light client side of the chain, providing permissionless high-throughput data availability (DA) for Ethereum Layer 2 (L2), and ensuring security with crypto-economic guarantees rather than reputation or hidden trust assumptions. Blobstream can also be used on celenium.io, allowing anyone to track the on-chain promise of Celestia data roots.
