Celestia releases roadmap to scale to 1 GB blocks on modular network

Celestia released a new roadmap to increase its block sizes to 1 gigabyte to improve data throughput and reduce rollup transaction fees. This initiative is part of Celestia’s broader strategy as a modular data availability blockchain that allows rollups to select their preferred execution layers.

Celestia is a modular blockchain network focused on data availability. It’s designed to simplify the launch of individual blockchains and is particularly useful for launching rollups and Layer 2 blockchains.

The latest roadmap features several upcoming technical upgrades, beginning with the Lemongrass upgrade, currently under development. Future enhancements include the introduction of a content-addressable mempool, node sharding, and further improvements to the data availability protocol, which aim to enhance the platform’s capacity for handling larger blocks.

Celestia’s current block size is 2 megabytes. As the network has announced plans to scale its block size to 1 GB, it can help significantly increase its data throughput and capacity to handle data from rollups.

Following the launch of its mainnet beta last year, Celestia has supported the deployment of 20 rollups, with Celestia blobs comprising 40% of the total data published. The development community has contributed to 24 Celestia Improvement Proposals (CIPs) across various core development teams.

Unlike traditional blockchain models, which focus on optimizing a single Layer 1 structure, Celestia’s architecture eliminates constraints related to execution layer overhead and state bloat. This allows developers more freedom in choosing virtual machines and smart contract programming languages.

Celestia separates the consensus layer — which ensures agreement on the network's state — from the execution layer, which processes transactions. By focusing on data availability, Celestia can handle many transactions for Layer 2 rollups without compromising security.
