On June 11th, Celestia, a modular blockchain network, announced on X platform that Blobstream has been launched on the Ethereum mainnet. Developed by Succinct Labs, Blobstream streams the commitment of Celestia data root to the Ethereum light client on-chain, 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 commitment of Celestia data root.
