Modular data availability for the OP Stack

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,

Celestia light node challenge

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

Intro to testing modular blockchain software

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

How modular blockchains create a world of abundance

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

The Blockspace Race

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
