At 14:00 UTC today, Celestia was successfully deployed to Mainnet Beta, codenamed Lemon Mint, marking the arrival of the first modular data availability network. Today marks a massive milestone for the Celestia community. What was once considered a wild moonshot is now a reality four years after the LazyLedger

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-class citizens when they can directly

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 ready to launch. Exploring the unexploredInitially,

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-throughput L2s as easily as they develop smart contracts.

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-minimisation that Celestia strives for is that

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 everything goes smoothly,

IntroductionOP 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. Modularity is a fundamental aspect of the OP Stack vision,

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 and more importantly, underutilized as

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 purpose-built for a specialty. This lets modular blockchains deliver abundant blockspace for cheap access

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 availability sampling. While these testnets proved

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. ETHDenverFor the main event, ETHDenver, we will give

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