Cardano Project Catalyst

We regularly apply for funding from individual funds of Cardano Project Catalyst, below you can see our history of applications for funding:

Closed Funding Rounds

• [ ] [Fund 6 - Ouroboros Rust Networking Crate](https://cardano.ideascale.com/a/dtd/Rust-Cardano-Networking-Crate/367442-48088), project not funded
  • 14 000 USD requested, but was over budget for Fund 6
• [ ] [Fund 3 - Ouroboros Rust Networking Crate](https://cardano.ideascale.com/a/dtd/Ouroboros-Networking-Rust-Crate/333161-48088), project not funded
  • 7 000 USD requested, but was over budget for Fund 3

Ouroboros Network Protocol Documenation

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

• Introduction to the design of Data Diffusion and Networking of Cardano Shelley

  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.

• The Shelley Networking Protocol

  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.

Wireshark Plug-in

• Wireshark Dissector for Ouroboros-Network in Lua

Emurgo CDDL CodeGen

• 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.
