Today we are proud to announce that Celestia Labs is acquiring Sovereign Labs. This acquisition establishes Celestia Labs as a full-stack custom blockchain development partner for companies building onchain, marking a new chapter for Celestia’s go-to-market strategy and ambitions. Why Sovereign L

Every blockchain claims to allow more transactions per second (TPS) than its competitors. Chains advertise figures from tens of thousands TPS (live today) up to several million for yet-to-be-released systems. At Celestia, we're pretty much never able to reproduce chains’ headline numbers against rea

This case study presents a novel use case of data availability and the team that is pioneering its first implementation: Midnight Network uses Celestia as the peer-to-peer layer for its Zswap offers, so counterparties can discover them and match. DA 4️⃣ P2P When we announced Fibre Blockspace in J

This case study explores Relay, an onchain interoperability product that scaled to broad adoption (100M+ transactions, and $20B+ in volume across 85+ chains) and why it built its own chain to settle it all. What is Relay Relay is a multichain payments network that allows users to spend any digita

Celestia’s next upgrade, Hibiscus (V7), is scheduled for mid-March. Hibiscus moves Celestia closer to resolving the tradeoff between sovereignty and interoperability, making networks built on Celestia feel more unified. It introduces two new features that enable better interoperability between netw

For years, the blockchain technology industry operated under the assumption that Layer 2s were subordinate extensions of a single parent Layer 1 like Ethereum. As the roadmap for Ethereum continues to shift, the relationship between base layers and the networks built upon them is being fundamentally

Celestia’s Vision 2.0 outlined three bandwidth regimes in blockchain history. The first era at 10KB/s enabled AMMs. The second at 1-10MB/s made onchain orderbooks viable for crypto trading. But the third era, targeting 1 Tb/s with the Fibre upgrade, is designed to put every

The highest-stakes onchain markets, including perp exchanges, orderbooks, and institutional rails, rely on data that cannot be public. Positions, balances, liquidations, and routing logic are inherently sensitive, yet hiding this data pushes risk back onto users and undermines the core promise of be

0. Tl;dr Mission: Build blockspace products that let high-volume markets come onchain. Vision: Every market in the world trades on open infrastructure, with permissionless read and write access to every orderbook. Principle: Social consensus is the final layer. Celestia provides infrastructure fo

Today, we’re closing the chapter on throughput. Celestia is introducing Fibre Blockspace, a new data availability protocol capable of sustaining 1Tb/s of blockspace across 500 nodes. That’s 1500x the throughput goal we set in our original roadmap over a year ago. Introducing Fibre The last decad

Celestia’s v6 upgrade, Matcha, is now live on Arabica testnet and on its way to Mainnet, marking the biggest upgrade yet. Matcha enables Celestia to scale up to 128MB blocks with a new high-throughput block propagation mechanism. This represents a big step towards the Celestia roadmap’s core

Introducing the first demo of Lazybridging, showcasing TIA transferred back and forth between Celestia and a ZK EVM rollup. This demo marks the first step towards Lazybridging on mainnet, where apps let users access any asset securely within 1 second. Lazybridging demo The Lazybridging demo shows

Celestia’s v4 mainnet upgrade, Lotus, is on the horizon. Lotus integrates Hyperlane as a Cosmos SDK module. Hyperlane enables direct TIA interop for new Celestia rollups and non-Celestia chains with Hyperlane deployments, such as Ethereum Mainnet, Base, Arbitrum One, and more. Lotus also makes sev

Today we're introducing mamo-1, a public testnet that pushes Celestia to new extremes. Built for applications at the frontier, mamo-1 delivers 128MB blocks and 21.33MB/s of permissionless throughput—offering the infrastructure needed to test real-world, high-throughput applications and prepare for t

gmamo, ETHDenver is around the corner, and of course, there’s a bunch of Celestia events on the schedule. Let's get into it. Mammoth hunt A small QR code will be hidden around the start of ETHDenver. The QR code will contain a prize for the first person to

Earlier this year, the Celestia roadmap was published. An important part of the roadmap is adding ZK verification natively to the Celestia base layer, so that rollups can directly bridge assets via Celestia. In this post, we explore how adding ZK to the base layer unlocks Lazybridging - the Celestia

The Lemongrass upgrade, deployed to Mainnet Beta in September, was Celestia’s first consensus upgrade. The upcoming Ginger upgrade, i.e. celestia-app v3, is the second. Ginger brings The Doubling, an immediate 2x increase to Celestia’s data availability throughput! In v3, this is achieved by decrea

The Celestia core developer community recently unveiled a roadmap to massively scale data throughput towards our next major destination: 1GB blocks. Today Celestia Labs is unveiling results from the proof-of-concept Mammoth Mini testnet that implements 88 MB blocks with an average of 27 MB/s of per

Celestia Mainnet Beta recently completed its first upgrade, introducing the first new set of features to the consensus network. The data availability (DA) network is scheduled to receive its first upgrade with Shwap - now activated on Arabica and Mocha testnets with v0.18.2 of celestia-node. Shwap

With Celestia underneath, developers can deploy high-throughput, unstoppable applications with full-stack customizability.

After several years of development, Celestia Mainnet Beta went live last year. Since then, an early ecosystem has taken form, with developers deploying the first 20 rollups and Celestia blobs represent 40% of total data published. Alongside growth of the early ecosystem, Celestia’s core developer c

A significant milestone is coming up for Celestia, in coordination with its community: The Lemongrass upgrade. This milestone contains many consensus layer changes, such as Interchain Accounts, Packet Forward Middleware, and CIP-10, a mechanism which simplifies future upgrades. The release of v2.0.
