Pallas Logo

Rust-native building blocks for the Cardano blockchain ecosystem

GitHub Crates.io GitHub Workflow Status

Introduction

Pallas is an expanding collection of modules that re-implements common Ouroboros / Cardano logic in native Rust. This crate doesn't provide any particular application, it is meant to be used as a base layer to facilitate the development of higher-level use-cases, such as explorers, wallets, etc (who knows, maybe even a full node in a far away future).

Unboxing

The repository is organized as a Cargo workspace. Each Pallas "building block" lives in its own crate. The root pallas crate serves as an all-in-one dependency that re-exports all of the other modules in an hierarchically organized fashion, using Cargo features to tailor the setup for each use-case.
