# Karyon
An infrastructure for peer-to-peer, decentralized, and collaborative software

> In molecular biology, a Karyon is essentially "a part of the cell
> containing DNA and RNA and responsible for growth and reproduction"
## Overview
Many developers around the world aspire to build peer-to-peer, decentralized
apps that are resilient, secure, and free from central control.
However, there are still not many libraries and tools available to build these
kinds of apps. This forces many developers to either abandon their ideas or
develop a new p2p network stack and tools from scratch. Such efforts are not
only time-consuming but also prone to errors and security vulnerabilities, as
each new implementation reintroduces potential weaknesses.
Karyon provides developers with the components and tools needed to create p2p
and decentralized apps and simplifies the complexities associated with building
them. Its primary goal is to make decentralization more accessible and
efficient for developers everywhere.
## Crates
- **[karyon core](./core)**: Essential utilities and core functionality.
- **[karyon net](./net)**: Provides a network interface for TCP, UDP, TLS, WebSocket, and Unix,
along with common network functionality.
- **[karyon p2p](./p2p)**: A lightweight, extensible, and customizable
peer-to-peer (p2p) network stack.
- **[karyon jsonrpc](./jsonrpc)**: A fast and lightweight async
[JSONRPC2.0](https://www.jsonrpc.org/specification) implementation.
- **karyon crdt**: A [CRDT](https://en.wikipedia.org/wiki/Conflict-free_replicated_data_type)
implementation for building collaborative software.
- **karyon base**: A lightweight, extensible database that operates with `karyon crdt`.
## Choosing the async runtime
All the crates support both **smol(async-std)** and **tokio** async runtimes.
The default is **smol**, but if you want to use **tokio**, you need to disable
the default features and then select the `tokio` feature.
## Docs
Online documentation for the main crates:
- [karyon_p2p](https://karyontech.github.io/karyon/karyon_p2p),
- [karyon_jsonrpc](https://karyontech.github.io/karyon/karyon_jsonrpc)
For the internal crates:
- [karyon_core](https://karyontech.github.io/karyon/karyon_core),
- [karyon_net](https://karyontech.github.io/karyon/karyon_net)
## Status
This project is a work in progress. The current focus is on shipping `karyon
crdt` and `karyon base`, along with major changes to the network stack. You can
check the [issues](https://github.com/karyontech/karyon/issues) for updates on
ongoing tasks.
