# Pallas
|
|
|
|
Rust-native building blocks for the Cardano blockchain ecosystem.
|
|
|
|
## Introduction
|
|
|
|
Pallas is an expanding collection of modules that re-implements common
|
|
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 the 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.
|
|
|
|
As already explained, _Pallas_ aims at being an expanding set of components. The following tables describe the currently available crates, as well as the planned ones.
