- Celestia plans to increase its block size to 1 gigabyte to enhance data throughput.
- Since last year’s launch, Celestia has deployed 20 rollups and its blobs make up 40% of published data.
- The new roadmap includes technical upgrades like content-addressable mempools and compact blocks to support high-throughput applications.
Celestia, a layer-1 data availability network, has revealed an ambitious technical roadmap to scale its block size to 1 gigabyte. According to a recent blog post, the Celestia Mainnet Beta launched last year after years of development, laying the foundation for an early ecosystem. Since then, developers have deployed the first 20 rollups, and Celestia blobs now account for 40% of the total data published.
As this ecosystem grows, the network’s core developers have been actively planning the next phase of the protocol, engaging in 16 public developer calls and forming a ZK working group with input from various teams.
The developer community has also drafted or proposed 24 Celestia Improvement Proposals (CIPs), contributed by six core dev entities. The team is preparing for major upgrades, starting with “Lemongrass,” alongside a newly unveiled technical roadmap featuring contributions from multiple teams.
A key focus of the roadmap is the relentless scaling of its block size to 1 gigabyte. This represents a substantial increase in data throughput, particularly benefiting the network’s rollup ecosystem. Unlike traditional permissionless blockchains, which face limitations in optimizing consensus and execution layers, Celestia’s unique architecture bypasses these constraints. It allows developers to work with any virtual machine (VM) or rollup framework, providing greater flexibility for high-throughput applications.
The roadmap outlines a series of technical innovations that will enable this scaling, including content-addressable mempools, compact blocks, internal node sharding, and data availability sampling improvements.
These advancements aim to achieve a data throughput that exceeds current monolithic blockchain structures. The network’s design could potentially handle many Visa-scale networks in parallel, unlocking the possibility for entirely on-chain applications that were once considered impractical.
Celestia Ensures Verifiability Across All Devices
In addition to scaling block size, Celestia is committed to ensuring that its blockspace is verifiable by anyone on any device. The community is working on a light node that can run directly in web browsers, ensuring that applications deployed on Celestia remain transparent and accessible to all. An early version of this light node, developed by Eiger at Lumina.rs, is already available for testing.
This roadmap reflects the network’s vision of abundant, verifiable, and frictionless blockspace, with the aim of making high-throughput decentralized applications accessible to developers and end users alike. The community continues to drive these updates through an open governance process, encouraging participation from anyone interested in shaping the network’s future.
