This repository hosts the implementation of the sequencer, the component of the Linea stack responsible for ordering transactions and building blocks, as well as executing them. It provides a set of Hyperledger Besu:Linea plugins.
It serves developers by making the Linea tech stack open source under the Apache 2.0 license.
Linea is a developer-ready layer 2 network scaling Ethereum. It's secured with a zero-knowledge rollup, built on lattice-based cryptography, and powered by Consensys.
If you already have an understanding of the tech stack, use our Quickstart guide.
Discover existing plugins and understand the plugin release process.
Linea's stack is made up of multiple repositories, these include:
- This repo, linea-sequencer: A set of Linea-Besu plugins for the sequencer and RPC nodes
- linea-monorepo: The main repository for the Linea stack & network
- linea-besu: Fork of Besu to implement the Linea-Besu client
- linea-tracer: Linea-Besu plugin which produces the traces that the constraint system applies and that serve as inputs to the prover
- linea-constraints: Implementation of the constraint system from the specification
- linea-specification: Specification of the constraint system defining Linea's zkEVM
Linea abstracts away the complexity of this technical architecture to allow developers to:
... and more.
