Celestia Activates Lemongrass Hard Fork to Expand Modular Data Availability Bandwidth

Celestia, the pioneer of modular data availability, has successfully executed its Lemongrass mainnet hard fork, representing the first major consensus upgrade in the network's production lifecycle. Backed by $55M+ from Bain Capital and Polychain, Celestia continues to establish the global benchmark for scalable rollup data availability.\n\nThe Lemongrass upgrade implements crucial Inter-Blockchain Communication (IBC) v3 routing, enabling rollups settling on Celestia to execute seamless cross-chain account abstractions without custom bridging infrastructure. Furthermore, enhanced packet forwarding and streamlined blob gas markets significantly reduce the cost for Layer 2 rollups to publish transaction data onto Celestia's data availability layer.\n\nAs dozens of modular appchains on OP Stack, Arbitrum Orbit, and Dymension RollApps rely on Celestia for high-bandwidth data posting, the Lemongrass upgrade reinforces TIA staking security while laying the groundwork for the foundation's 1-gigabyte block throughput roadmap.
