Today, we introduce the Celestia Foundation, a non-profit organization based in Liechtenstein. The Foundation’s purpose is to guide the Celestia ecosystem and uphold its values. A core belief of the Celestia community is that users should be first-class citizens of networks. Users become first-clas

The journey began in 2019 with the ambitious goal of creating a modular blockchain ecosystem with data availability layers and “execution engines” that seamlessly integrate. This vision has evolved into a thriving and collaborative ecosystem. Now, after years of development, the Celestia network is

Today Celestia Labs introduces Blobstream, which streams Celestia’s modular data availability layer to Ethereum. Formerly known as the Quantum Gravity Bridge (QGB), Blobstream relays commitments of Celestia’s data root using an onchain light client, enabling Ethereum developers to create high-throu

The Celestia Foundation is pleased to announce the Celestia Improvement Proposal (CIP) Process. The CIP process aims to coordinate technical proposals in the Celestia community to help improve the network across the modular stack, including core protocol upgrades. A vital aspect of the trust-minimi

Celestia’s genesis block, expected later this year, will start the first modular data availability network. With it will arrive TIA, the native asset of Celestia. Like in other permissionless protocols, TIA enables participation in network consensus and decentralised governance of network parameter

Not long ago, images of light nodes started popping up all over Twitter. Some were photoshopped onto DJ decks, and others showcased light nodes running next to waterfalls. During it all, we announced the light node challenge to spur the community’s creativity. Now that the light node challenge has

Concluding the Blockspace Race

The Celestia community has spent months stress-testing the Celestia network during the Blockspace Race. And now Oolong is being unveiled. Named after the Chinese tea, Oolong is the most recent upgrade to Arabica Devnet and Mocha Testnet. This upgrade serves as a release candidate for mainnet. If eve

Introduction OP Stack has gained significant traction among rollup developers since its announcement last year. It is embraced by both developers creating new rollups and modular infrastructure providers like Caldera and Conduit, that enable developers to quickly launch their own rollups. Modulari

Gm modularists, Members from the Celestia Labs team are heading to Prague for the Gateway conference and ETH prague! We plan on giving talks, participating on panels, and hosting events throughout the week. Be sure to find any of our team during these events if you want to get in

This week marks the 4th anniversary of the LazyLedger whitepaper. To commemorate, we’re announcing the Light Node Challenge, a contest to find the most creative, daring, and entertaining ways that people can run a Celestia light node. The challenge starts today and ends June 30, 2023. There will be

Naïve bugs and common issues in production networks are problems that threaten the resiliency of decentralized blockchains. This is an especially important problem given the number of users and applications that are dependent on these blockchains. We want to highlight a topic that is under-discussed

Scarcity negatively impacts monolithic blockchains users two ways. First, scarce blockspace makes blockchains expensive for users. Second, scarcity of choice limits the options developers, restricting innovation. Modular blockchains decouple consensus from execution, enabling blockchains to be purp

We are excited to introduce the Blockspace Race, Celestia’s incentivized testnet program! The Blockspace Race is the largest ever testnet to support data availability sampling, with 700+  sampling light nodes. Throughout 2022, we shipped multiple testnets including Mamaki, the first to support data

Neutral and independent from Celestia, Rollkit serves as a community-led public good that empowers developers with the freedom to deploy throughout the modular stack and accelerate innovation

Gm modularists, Celestia Labs is heading to ETHDenver! We look forward to meeting many teams and builders during our time there. Be sure to find any of our team during events to reach out and discuss all things Celestia and modular blockchains. ETHDenver For the main event, ETHDenver, we will

Modular testnets bring a faster erasure coding library that speeds up the encoder by 30x

You’ve probably heard it before. Celestia is the first modular blockchain network. But what is a modular blockchain, and how does Celestia fit into this? That’s what this post is all about - the brief version anyway. TLDR * The first approach to building blockchains was a monolithic design where

Celestia is building a modular consensus and data network so that anyone can easily deploy their own blockchain with minimal overhead. Celestia’s new modular blockchain architecture is made to supercharge the scale and rate of Web3 innovation in the next decade.

28 individuals and teams were selected for the inaugural cohort of Modular Fellows. Spanning execution layers, rollup infrastructure, DeFi apps, and more, Cohort One is a promising seed in the fast-emerging Celestia ecosystem.

¡Hola! The Celestia team has a packed agenda in Colombia with two main events happening in the two biggest cities in the country; Cosmoverse in Medellin and Devcon in Bogota. The team will first travel to Cosmoverse in Medellin, which takes place from September 26-28. Celestia is proud to

The Celestia team is traveling to Berlin for Berlin Blockchain Week to attend a variety of different crypto events. First up, the team will be attending Dappcon. Be sure to find any of our team over there with the Celestia T-Shirt on to talk all things Celestia and Modularity.

The Celestia team will be travelling to San Francisco to attend the Science of Blockchain Conference 2022 at Stanford. At the conference, a paper co-authored by all three Celestia founders: Mustafa Al-Bassam, Ismail Khoffi, and John Adler will be presented on Wednesday, Aug. 31, 2022 at 3:30

A program designed to empower modular builders with the right resources to build the future of scalable and sovereign blockchain networks.

It’s been a short while since we deployed Mamaki, the Celestia testnet. With a successful launch, we rolled out our alpha data availability API and introduced data availability sampling - a key ingredient in Celestia’s scalable architecture. In the meantime, we introduced sovereign rollups to the w

Greetings, Seoul! We are very excited about the Celestia Labs team’s attendance in Seoul for HackAtom, BuidlAsia and Korea Blockchain Week. With back-to-back events spanning over two weeks, this will provide an amazing opportunity to connect with the team to chat about building modular.   First up

Bonjour! The Celestia Labs team is heading to Paris for ETHCC week to share the vision of modularity. We couldn’t be more excited to talk about what motivates us to build modular at the various events. At ETHCC, two Celestia Labs team members will give talks: * John Adler (CRO)

Most applications using Celestia as their consensus and data availability layer will be hosted on rollups. As a new layer 2 solution first proposed to increase transaction throughput, rollups may be the future home of almost all blockchain applications whether they use Celestia, Ethereum or another

It's been a whirlwind the past few months, first and foremost with the successful launch of the Mamaki testnet. The data availability nodes on Mamaki have been working as intended while pending upgrades, such as bad encoding fraud proofs, were fully rolled out. We conducted various other internal t
