This repository hosts a Linea tracing implementation for Hyperledger Besu based on an implementation in Go.
Tracing refers to the process of extracting data from the execution of an EVM client in order to construct large matrices known as execution traces. Execution traces are subject to the constraint system specified in the linea-specification repo and implemented in the linea-constraints repo.
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 Get Started guide.
Discover existing plugins and understand the plugin release process.
Linea's stack is made up of multiple repositories, these include:
- This repo, linea-tracer: Linea-Besu plugin which produces the traces that the constraint system applies and that serve as inputs to the prover
This repository contains the elements of the Linea stack responsible for this process.
- linea-monorepo: The main repository for the Linea stack & network
- linea-besu: Fork of Besu to implement the Linea-Besu client
- linea-sequencer: A set of Linea-Besu plugins for the sequencer and RPC nodes
- 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.
