Abstract
This paper presents SkillSwap, a modular peer-to- peer digital learning ecosystem designed to enable structured skill exchange through a credit-governed participation model. Unlike traditional Learning Management Systems (LMS) that rely on centralized, one-directional instructional delivery, SkillSwap introduces a decentralized reciprocal framework where users dynamically alternate between instructor and learner roles.
The system is implemented using a full- stack architecture comprising a REST- driven backend (Node.js, Express.js), a document- oriented database (MongoDB Atlas), secure token-based authentication (JWT), encrypted credential storage (bcrypt), and a WebRTC-enabled live lecture integration layer utilizing the Jitsi Meet API. The architecture ensures secure route-level access control, atomic credit transaction validation, and optimized indexed database queries.
Performance benchmarking demonstrates stable REST API latency under concurrent usage conditions and reliable live session handling within browser- native environments. SkillSwap establishes a calable, secure, and institution-ready framework for decentralized academic collaboration and structured knowledge governance.
Keywords: Peer-to-Peer Learning, REST Architecture, WebRTC Integration, JWT Authentication, MongoDB, Credit-Based Governance, Digital Learning Ecosystem.
