The program was intentionally structured to support builders at varying skill levels, guiding them from early-stage ideation through to deployable Minimum Viable Products (MVPs). Through strategic alignment with the Scroll ecosystem, the hackathon contributed directly to Layer-2 developer adoption while supporting the growth of an emerging community of African blockchain builders focused on real-world consumer applications. ## **Overview &Objectives** The Online Vibe Coding Hackathon was designed with clear technical, ecosystem, and market-oriented objectives to ensure measurable outcomes. - **Developer Enablement** Equip African developers with the technical, architectural, and product-thinking skills required to build scalable, mobile-first blockchain applications. Emphasis was placed on hands-on learning, applied frameworks, and practical implementation rather than purely theoretical instruction. - **Ecosystem Growth** Introduce participants to Scroll’s zkEVM-based Layer-2 infrastructure, ensuring familiarity with its architecture, tooling, and deployment processes. The objective was to encourage sustained participation in the Scroll ecosystem beyond the duration of the hackathon. - **AI-Augmented Development** Demonstrate how AI tools can be responsibly integrated into modern development workflows. This included prompt engineering, code verification, refactoring strategies, and evaluation of AI-generated outputs to ensure security and maintainability. - **Market-Relevant Innovation** Encourage the development of consumer-focused blockchain solutions that reflect African market realities, including mobile-first usage, low bandwidth environments, mobile money integration, and trust-sensitive user experiences. Organized by **[KayabaLabs](https://kayabalabs.com/home)**, the hackathon was delivered as an intensive two-week online program targeting developers, students, entrepreneurs, and early-stage founders across Africa. The virtual format enabled broad participation while maintaining structured coordination and accountability. Participants followed a guided curriculum that blended: - Theory-driven instruction to establish shared technical foundations - Applied workshops focused on real-world use cases - A supervised MVP build phase emphasizing delivery and execution Throughout the program, participants were encouraged to think beyond proof-of-concept development and instead focus on building **deployable, user-facing products**. ## **Highlights** Key components of the program included: - **Hackathon-Style Builder Workshops:** Practical technical sessions focused on real-world application development. - **Intensive MVP Nursery:** A guided environment where teams transformed early concepts into market-ready prototypes. - **Vibe Coding Hackathon:** Hands-on development of crypto consumer applications using AI-assisted workflows. - **Scroll Architecture Deep Dives:** Technical sessions covering Scroll’s zkEVM architecture and Ethereum scaling via zero-knowledge proofs. ## **Learning Outcomes** By the end of the program, participants demonstrated measurable growth across technical, product, and collaboration dimensions. - **Product Scoping and Design** Teams applied structured scoping methodologies and produced draft Product Requirement Documents (PRDs) that defined clear MVP boundaries, features, and user journeys. - **Accelerated Development Cycles** Participants adopted AI-assisted workflows and standardized development frameworks to reduce iteration time while maintaining code quality. - **Scalable Application Design** Applications were designed with future growth in mind, accounting for mobile-first usage, consumer scale, and integration with blockchain infrastructure. - **Code Evaluation and Improvement** Through peer reviews and live demonstrations, participants learned to critically assess both human-written and AI-generated code, reinforcing best practices in verification and refactoring. ## **Program Timeline** ### **Week 1: Education & Technical Foundations** Week 1 focused on establishing shared foundations in product thinking, design, blockchain architecture, and AI-assisted development. **Workshop 1** **Date:** December 8th | **Time:** 4:30 PM GMT **Topic:** Vibe Coding Framework & Product Scoping **Host:** Hussein Suhuyini **Workshop Notes/Slides :** [Scoping and PRD Workshop Notes - Google Docs](https://docs.google.com/document/d/1wAUlJMK-eEVHtMCXw6reRKJfn9WjHDCEZibQi0K4LlY/edit?usp=sharing) **Workshop** **Recording :** [https://youtu.be/lgjaX4k5vL4](https://youtu.be/lgjaX4k5vL4) Focus Areas: - MVP scoping and Product Requirement Document development - Standardized user stories instances for secure, maintainable code - Refactoring protocols for developing technical and design features components **Workshop 2** **Date:** December 9th | **Time:** 4:30 PM GMT **Topic:** UI/UX Mobile Design Principles **Host:** Kenneth Ocran **Workshop Notes/Slides :** [https://drive.google.com/file/d/1ozj5PcnDw9TlF6v\_LQ3JOrA9Qn86PUoA/view?usp=sharing](https://drive.google.com/file/d/1ozj5PcnDw9TlF6v_LQ3JOrA9Qn86PUoA/view?usp=sharing) **Workshop Recording :** [https://youtu.be/lvH73FcBacI](https://youtu.be/lvH73FcBacI) Focus Areas: - Designing for low-end devices and high data costs - UX patterns for mobile money–to–crypto workflows (e.g., M-Pesa, MTN MoMo) - Instant confirmation and trust-building interface patterns - Cultural UX approaches combining Western design systems with African local context **Workshop 3Date:** December 10th | **Time:** 4:30 PM GMT **Topic:** Zero-Knowledge Proofs on Scroll (Technical Deep Dive) **Host:** John Okyere **Workshop Notes/Slides :** [Scoping and PRD Workshop Notes - Google Docs](https://docs.google.com/document/d/1wAUlJMK-eEVHtMCXw6reRKJfn9WjHDCEZibQi0K4LlY/edit?usp=sharing) **Workshop** **Recording :** [https://youtu.be/Mf4FVLSs0Pw](https://youtu.be/Mf4FVLSs0Pw) Focus Areas: - Core concepts and cryptographic primitives behind zero-knowledge proofs - The role of Scroll’s zkEVM architecture in Ethereum scaling - Deployment of applications on the Scroll Testnet and Mainnet **Workshop 4Date:** December 15th | **Time:** 8:30 PM GMT **Topic:** A prompt engineering framework for vibe-coding **Host:** Hussein Suhuyini **Workshop Recording :** [https://x.com/i/spaces/1BdxYZOQBABKX?s=20](https://x.com/i/spaces/1BdxYZOQBABKX?s=20) Focus Areas: - Standardized prompt engineering techniques for secure, maintainable code - Verification protocols for understanding AI-generated components - Refactoring methodologies tailored for AI-assisted codebases ### **Week 2: Build & Submission Phase** The second week transitioned participants from learning to execution. - Teams commenced full MVP development following the completion of all educational workshops. - Development was conducted asynchronously, supported by shared communication channels and regular sprint-style check-ins. - Teams aligned their work with the standards and frameworks introduced during Week 1.
