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 world -

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, our CEO Mustafa

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 platform for consensus and

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 tests for

Today, we are excited to announce the launch of the new Celestia “Mamaki” testnet! This marks the next step in our road towards Celestia mainnet - a modular blockchain network that decouples consensus from execution. We are one step closer to enabling anyone to easily deploy their own blockchain, without

Blockchains need to guarantee data availability (DA), especially in the case of rollup and layer 2 (L2) chains. The blockchain data availability problem goes like this: participants of blockchain networks can get locked out from interpreting the state or further updating it when block producers advance the state of the

tl;dr: This post introduces the Quantum Gravity Bridge project, a Celestia to Ethereum data availability (DA) bridge. From the onset of DeFi Summer in 2020, through the eruption of NFTs in 2021, and now an escalation of DAOs, the demand for blockspace on Ethereum has exploded. The deadly combo

We are excited to announce that we have successfully launched Celestia devnet! On a cold November day in Berlin, our engineers were huddled in a conference room clad in Celestia hoodies. Suddenly, they erupted into cheers of elation. On their computer terminal windows were the following messages: Terminal output from

We live in a multi-chain world. The idea that decentralized apps will all use the same shared smart contract blockchain is dead in practice. Ethereum is pivoting to a roadmap where apps have their own rollup chains, multi-chain ecosystems such as Cosmos and Polkadot are rising in popularity, as well

Today we’re thrilled to announce that we’ve shipped our minimum viable product (MVP)—a data availability sampling light client. This marks the first major milestone in our roadmap to build a universal consensus network allowing anyone to deploy their own custom blockchain in minutes. TL;DRData availability sampling

We’re excited to announce that we are henceforth rebranding LazyLedger as Celestia! Names are important. A good name communicates vision and inspires a community to rally behind it. Although LazyLedger is catchy and succinctly captures the minimal nature of our protocol, we wanted a name with more mass appeal.
