Celestia

Celestia, formerly known as LazyLedger, is the world's first modular blockchain network.

It provides a pluggable consensus and data availability layer that lets anyone deploy a decentralized blockchain quickly without bootstrapping a new consensus network.

By modularizing the blockchain technology stack and decoupling the consensus from the application execution layer, Celestia opens up new possibilities for building decentralized applications.

Designed to simplify deployment and experimentation, Celestia supports diverse chains and developer workloads while keeping the core lightweight and extensible.
