README
Rust-native building blocks for the Cardano blockchain ecosystem
## 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.
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.
### Ouroboros Network
| Crates | Description |
| --------------------------------------------- | ----------------------------------------------------------------------- |
| [pallas-network](/pallas-network) | Network stack providing a multiplexer and mini-protocol implementations |
### Ouroboros Consensus
| Crates | Description |
| ----------------- | --------------------------------------------------------- |
| pallas-leadership | Implementation of the slot leadership selection algorithm |
| pallas-selection | Implementation of the consensus chain-selection algorithm |
### Cardano Ledger
| Crates | Description |
| --------------------------------------- | ----------------------------------------------------------------------- |
| [pallas-primitives](/pallas-primitives) | Ledger primitives and cbor codec for the different Cardano eras |
| [pallas-traverse](/pallas-traverse) | Utilities to traverse over multi-era block data |
| [pallas-addresses](/pallas-addresses) | Encode / decode Cardano addresses of any type |
| pallas-ticking | Time passage implementation for consensus algorithm |
| pallas-applying | Logic for validating and applying new blocks and txs to the chain state |
| pallas-forecasting | Ledger forecasting algorithm to be used by the consensus layer |
### Shared
| Crates | Description |
| ------------------------------- | -------------------------------------------------- |
| [pallas-crypto](/pallas-crypto) | Shared Cryptographic primitives |
| [pallas-codec](/pallas-codec) | Shared CBOR encoding / decoding using minicbor lib |
| [pallas-math](/pallas-math) | Shared mathematics functions |
