Please describe your proposed solution

We propose a comprehensive upgrade of PyCardano to align it with the latest specifications introduced by the Chang hardfork. This upgrade will not only restore compatibility with existing functionalities but also introduce support for new features, such as Decentralized Representative (DRep) voting.

Approach Rationale

Our approach focuses on a thorough update rather than a quick fix for several reasons:

1. Future-proofing: By aligning closely with the new specifications, we reduce the likelihood of future incompatibilities.
2. Feature expansion: This upgrade allows us to incorporate new Cardano features, e.g. DRep , enhancing PyCardano's utility.
3. Community support: A comprehensive update demonstrates our commitment to the Cardano ecosystem, encouraging continued use and development of Python-based Cardano projects.

Engagement

This project will directly engage:

1. Cardano developers using Python
2. Project managers and teams building on Cardano
3. The broader Cardano community interested in ecosystem growth

Impact Demonstration

We will demonstrate the impact of our solution through:

1. Comprehensive testing to ensure full compatibility with post-Chang hardfork Cardano network
2. Documentation and examples of new feature implementations, such as DRep voting
3. Monitoring of PyCardano adoption rates and usage statistics post-upgrade
4. Gathering feedback from the developer community on the upgraded library's performance and utility

Importance to Cardano

This upgrade is crucial for Cardano because:

1. It maintains Python as a viable language for Cardano development, broadening the ecosystem's developer base
2. It ensures that existing Python-based projects can continue to function and evolve
3. It demonstrates Cardano's commitment to supporting diverse development tools and languages
4. It facilitates the adoption of new Cardano features like DRep voting in Python-based applications

By implementing this solution, we aim to reinforce PyCardano's position as a cornerstone library in the Cardano ecosystem, fostering continued growth, innovation, and diversity in Cardano-based development.

Please define the positive impact your project will have on the wider Cardano community

How does the cost of the project represent value for money for the Cardano ecosystem?

Value for Money in the Cardano Ecosystem:

1. Widespread Impact: PyCardano is a cornerstone library in the Cardano ecosystem, with over 100 open-source projects depending on it. This wide adoption means that the proposed upgrade will have a far-reaching positive impact, benefiting not just direct users of PyCardano, but also the users and stakeholders of all dependent projects.
2. Enabling Critical Infrastructure: Many influential projects in the Cardano ecosystem are built on PyCardano, including Charli3 Dendrite and OpShin. By upgrading PyCardano, we're not just improving a single library, but enhancing the foundation upon which a significant portion of the Cardano Python ecosystem is built.
3. Cost-Effective Ecosystem-Wide Upgrade: The total project cost of 200,000 ADA represents a highly efficient investment when considering the alternative - if each of the 100+ projects depending on PyCardano had to individually adapt to the Chang hardfork, the cumulative cost and effort would be substantially higher.
4. Maintaining Ecosystem Diversity: By ensuring PyCardano remains compatible with the latest Cardano protocols, we're preserving Python as a viable language for Cardano development. This language diversity is crucial for attracting and retaining a broad developer base, which in turn drives innovation and growth in the Cardano ecosystem.
5. Future-Proofing Investment: The upgrade doesn't just address current compatibility issues; it also sets up PyCardano to more easily incorporate future Cardano updates. This forward-looking approach provides long-term value, reducing the need for major overhauls in the future.
6. Skilled Expertise: The project will be led by Jerry, the original creator of PyCardano. His deep familiarity with both the library and the Cardano ecosystem ensures efficient use of resources, minimizing wasted effort and maximizing the value delivered per ADA spent.
7. Open-Source Benefits: As an open-source project, the improvements made to PyCardano will be freely available to the entire Cardano community. This magnifies the value of the investment, as it can be leveraged by any developer or project without additional cost.
