[SOLUTION] Please describe your proposed solution.

Our proposal is focused on significantly enhancing the debugging experience for developers working with UPLC and Aiken on the Cardano blockchain. We plan to develop a time-traveling debugger for UPLC. This tool will allow developers to execute their compiled UPLC code step-by-step, inspect the state at each step, and even navigate backwards in time. Additionally, if the code was compiled from Aiken, it will expose the Aiken code that produced the resulting UPLC. The goal is to make the debugging process more intuitive and efficient, helping developers quickly identify and resolve issues in their smart contracts.

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

This debugger will significantly overhaul the experience for Cardano smart contract developers, enabling more efficient and effective debugging. We will measure our impact through developer adoption rates and feedback, as well as observed improvements in debugging speed and ease. We will dog-food the tool for our own development, open source the code, and share the tool and accompanying resources widely within the Cardano community.

[CAPABILITY & FEASIBILITY] What is your capability to deliver your project with high levels of trust and accountability? How do you intend to validate if your approach is feasible?

Our team, comprising experienced blockchain developers and software engineers, has a proven track record in delivering high-quality development tools. We will validate our approach through continuous testing and community feedback, ensuring our solution meets the real-world needs of Aiken developers.
