True-Trail: A Blockchain-based Decentralized Skill Verification and Employer Insight System

This paper presents True-Trail, a blockchain- based decentralized skill verification and employer insight system designed to address the challenges of unverifiable skill claims, fraudulent certifications, and hiring bias in modern recruitment. The system integrates generative AI and blockchain smart contracts to ensure transparency and tamper- proof verification of candidate skills. Users submit claims supported by evidence such as code repositories, certificates, or videos, which are evaluated through AI-driven contextual assessments. Once verified, each claim is immutably recorded on the blockchain and linked to the candidates decentralized profile. Employers access a Talent Explorer Dashboard that provides verified skill records, reputation metrics, growth analytics, and candidate comparison tools, enabling data-driven hiring decisions. By combining blockchain security with AI- driven contextual evaluation, True-Trail enhances trust in recruitment, reduces fraudulent claims, and introduces a scalable framework for decentralized professional reputation management. Future enhancements include integration with decentralized identity (DID) solutions and deployment at scale within enterprise recruitment systems.
