Cardano Rust Ouroboros Network

This crate implements the networking layer for the Ouroboros blockchain protocol. This networking crate is undergoing active refactoring to use Tokio (see Project); meanwhile it may be reasonable to use pallas, specifically pallas-miniprotocols and pallas-multiplexer which use MSPC channels which currenlty provide more stability.

Ouroboros Network Protocol Documenation

There are two documents which describe various levels of the networking layer of the Cardano Node Shelley implementation:

This document explains the technical requirements and key constraints for the networking layer of the Cardano Shelley implementation of Ouroboros Praos. This is a design document.

This document is a technical specification of the networking protocol. It includes serialisation formats, necessary details of multiplexer and technical specifications of mini-protocols used by either node-to-node and node-to-client flavors of the protocol.

Emurgo CDDL CodeGen

Codegen serialization logic for CBOR automatically from a CDDL specification.

Instead of hand-writing CBOR code and writing tests to make sure it matches your CDDL spec, it's much faster to just generate the code from the spec! It will save time and make it easier to keep all your code in sync with any changes to your specification.

You can learn more about CDDL here.
