ClashVerse: A Real-Time 1v1 Coding Battle System and Secure Code Execution

Abstract: Programming practice platforms are widely used to improve problem-solving skills among students and developers. However, most existing platforms focus primarily on individual coding practice and lack real-time interaction between users. This limitation reduces engagement and restricts opportunities for competitive and collaborative learning.

To address this gap, this paper presents ClashVerse, a real-time 1v1 coding battle platform designed to make programming practice more interactive and engaging. The system uses an AI-based matchmaking algorithm to pair users based on their skill level. Participants solve the same programming problem simultaneously using an online code editor, creating a competitive environment.

The submitted solutions are executed securely using the Judge0 API, and performance is evaluated based on correctness and execution efficiency. The platform also updates leaderboards dynamically to reflect user performance. By integrating real-time interaction, gamification, and secure code execution, ClashVerse aims to provide an engaging and competitive platform for coding practice.
