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