ethlambda: devnet 5 and beyond

We already introduced ethlambda, our Lean Consensus client. We also wrote a blog post about devnet 4, which introduced recursive aggregation. Now that devnet 5 is implemented and in interop testing, it's a good time to recap the devnets so far and look at the candidates for the

Finality in leanConsensus: How ethlambda Implements 3SF-mini

Finality in leanConsensus: How ethlambda Implements 3SF-mini

In our previous post, we covered how ethlambda uses LMD-GHOST and ended with an open question: how does the protocol decide when a block is permanent and the chain tip can no longer be reorged? This post covers the other half of consensus: 3-Slot Finality, minimal version.

Fork Choice in leanConsensus: How ethlambda Implements LMD-GHOST

Fork Choice in leanConsensus: How ethlambda Implements LMD-GHOST

This is a follow-up to our posts on ethlambda's architecture. Here we explain the two core consensus mechanisms that ethlambda implements: LMD-GHOST for fork choice and 3SF-mini for finality.

Building a Minimalist Post-Quantum Ethereum Client: ethlambda's Architecture

Building a Minimalist Post-Quantum Ethereum Client: ethlambda's Architecture

This is a follow-up to our post on building a post-quantum Ethereum client. Here we detail ethlambda's minimalist architecture.

Ethlambda: Building a post-quantum Ethereum client with the help of shared tooling

Ethlambda: Building a post-quantum Ethereum client with the help of shared tooling

This is a follow-up to our introduction of ethlambda, in which we cover what a Lean Consensus client consists of and what tooling facilitates its development.
