CommitFit: A Blockchain-Based Fitness Platform with Financial Incentives and Decentralized Activity Verification for Enhanced User Engagement

Abstract

This paper presents CommitFit, a blockchain-based fitness platform designed to enhance user engagement and data security through financial incentives and decentralized attestation protocols. The architecture integrates modular layers comprising a secure frontend, AI-driven backend verification, and Ethereum smart contracts for automated staking and non-fungible token (NFT) rewards. Empirical evaluation demonstrates significant improvements in user retention and goal completion rates compared to traditional systems, with notable accuracy in AI-based activity verification. The platform addresses critical challenges such as privacy, scalability, and integration with wearable devices. Comparative analysis with existing fitness solutions highlights CommitFit's advancements and future potential for broader applications in secure, decentralized health data management.
