Odaily Planet Daily News Celestia is developing its roadmap to expand its scale to 1GB blocks, aiming to significantly increase data throughput and reduce rollup transaction fees. Celestia's first upgrade, called Lemongrass, is currently under development. The roadmap to 1GB blocks will involve multiple technical upgrades, including content-addressed memory pools, node sharding, and enhanced availability sampling protocols. In addition to expansion, Celestia also aims to ensure that its block space can be verified by anyone on any device, through light nodes that can be run in a web browser.
