Lodestar is a Typescript ecosystem for Ethereum consensus, developed by ChainSafe Systems. Our flagship products are our production-capable beacon chain and validator client. In addition, we maintain public repositories of useful tools for public use. Some of these libraries include BLS, SSZ, Discv5, Gossipsub, and Noise.

Work was completed to support the Ethereum ecosystem by most recently enabling EIP-4844 blobs to benefit L2s, reducing tx costs of L2 fees and increasing client diversity at the L1 protocol level.

Lodestar’s niche is in its implementation language, TypeScript. Our software and tooling is uniquely situated as the go-to for researchers and developers for rapid prototyping such as our Prover, a verified web3 provider using light clients to increase decentralization and security of the JSON-RPC. Millions of developers around the world are familiar with Typescript, and Lodestar’s high-quality codebases are excellent introductions to the Ethereum world. With the goal of increasing client diversity and attracting new talent from one of the largest groups of developers in the world.

We fully support other teams in Protocol and projects which indirectly fund client team implementors such as Protocol Guild.
