[SOLUTION] Please describe your proposed solution

What is Midnight?

Midnight is a data-protection blockchain designed to safeguard user data while focusing on security, compliance, and developer experience. Input Output Global (IOG) is developing Midnight and Midnight will be the first partner chain of Cardano. 

Problem

Given that Midnight is still in testnet, there's currently no smart contract library to help developers accelerate their work on this platform. Our goal is to address this gap so that when Midnight's mainnet launches, developers can build on it securely and efficiently. 

Solution

Our proposed solution is to develop and maintain an open-source library of smart contracts specifically designed for the Midnight blockchain. This library will initially include three essential smart contracts:

1. Escrow Contract: Facilitates secure transactions between parties by holding funds until predetermined conditions are met.
2. Dispute Resolution Contract: Provides a framework for resolving conflicts between parties in a decentralized manner.
3. Crowdfunding Contract: Enables decentralized fundraising campaigns with built-in accountability and transparency.

We perceive the problem as a lack of standardized, secure, and efficient smart contract templates for the Midnight blockchain. By providing these foundational contracts, we aim to accelerate development, enhance security, and foster innovation within the Midnight ecosystem.

Our approach is rooted in the principles of open-source development, community collaboration, and security-first design. We believe that by creating a shared resource, we can collectively build a more robust and trustworthy blockchain ecosystem.

This project will engage developers, entrepreneurs, and businesses looking to build on the Midnight blockchain. By providing them with well-tested, secure smart contract templates, we lower the barrier to entry and reduce the risk of vulnerabilities in new projects.

To demonstrate our impact, we will track metrics such as:

• Number of projects utilizing our smart contract library
• Community contributions and improvements to the contracts
• Reduction in smart contract vulnerabilities in projects using our library
• Time saved in development and auditing processes

What makes our solution unique is its focus on the specific needs and features of the Midnight blockchain, combined with a commitment to open-source principles. This project will benefit the entire Midnight ecosystem, from individual developers to large-scale applications.

This initiative is important to Cardano as it supports the growth and adoption of Midnight, a key project in the Cardano ecosystem. This library will simplify the onboarding process for developers unfamiliar with the Cardano ecosystem, making it easier for them to start building on Cardano and Midnight. As a result, it will contribute to the growth of the Cardano ecosystem. By providing essential tools and resources, we contribute to Cardano's vision of creating a more inclusive and accessible blockchain ecosystem.

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

Our project, the Open-Source Smart Contract Library for Midnight, will have a significant positive impact on the wider Cardano community in several ways:

• Accelerating development on Midnight: By providing ready-to-use, secure smart contract templates, we'll enable faster and more efficient development of applications on the Midnight blockchain.
• Enhancing security: Our well-audited contracts will serve as a benchmark for security best practices, potentially reducing vulnerabilities in the Midnight ecosystem.
• Fostering innovation: With lower barriers to entry, more developers and entrepreneurs can bring their ideas to life on Midnight, driving innovation within the Cardano ecosystem.
• Building community: Our open-source approach will encourage collaboration and knowledge sharing among Cardano and Midnight developers.

To measure the impact of our project, we will track and analyze the following metrics:

• Adoption rate: Number of projects utilizing our smart contract library
• Community engagement: Quantity and quality of contributions to the library from the community
• Development efficiency: Average time saved in development and auditing processes for projects using our library
• Ecosystem growth: Increase in the number of new projects launched on Midnight

We plan to share the outputs and opportunities resulting from our project through various channels:

• GitHub repository: All our code, documentation, and development progress will be publicly available on GitHub.
• Regular blog posts: We'll publish updates, case studies, and best practices on our project website and Medium.
• Community forums: We'll actively participate in Cardano and Midnight community forums, sharing insights and gathering feedback.
• Workshops and webinars: We'll organize educational events to help developers understand and utilize our library effectively.

By openly sharing our progress, findings, and resources, we aim to maximize the positive impact of our project on the entire Cardano community and contribute to the growth and success of the Midnight blockchain.

[VALUE FOR MONEY] How does the cost of the project represent value for money for the Cardano ecosystem?

The cost of this project represents excellent value for money for the Cardano ecosystem for several reasons:

• High-quality, open-source resources: The project will deliver a comprehensive, professionally developed smart contract library that will be freely available to all Midnight developers, accelerating ecosystem growth.
• Expertise and experience: Our team comprises highly skilled professionals with extensive experience in blockchain development, particularly within the Cardano ecosystem. This expertise ensures efficient development and high-quality outputs.
• Cost-effective rates: Our hourly rate of $40 is competitive for blockchain development, especially considering the specialized skills required for Midnight. This rate is below average for similar expertise in major tech hubs, offering good value. The average salaries of product designers ($72 per hour), developers ($68 per hour), and product managers ($65 per hour) are quite high. (See here for more details.) This shows our conscious effort to manage costs effectively while still delivering quality results. The transparency in our budget breakdown, based on previous project experiences, further supports the notion of cost-effectiveness.
• Long-term ecosystem benefits: By providing a robust foundation for smart contract development on Midnight, this project will foster innovation, improve security, and reduce development costs across the ecosystem.
• Educational resources: The included documentation and tutorials will have a multiplier effect, enabling more developers to effectively build on Midnight.

Furthermore, our budget is carefully allocated to maximize impact. We've prioritized core development tasks while also ensuring comprehensive testing, documentation, and community engagement. This balanced approach ensures that the project delivers immediate value while also supporting long-term ecosystem growth.

Lastly, as a team deeply committed to the Cardano ecosystem, we're investing significant additional resources beyond what's covered in this budget. This includes ongoing community support, maintenance, and future enhancements to the library, further increasing the long-term value proposition of this project.
