Inspiration Campus hackathons often suffer from unfair project selection, lack of team diversity, and voting manipulation. We wanted to empower students to transparently share ideas, vote fairly, and collaborate efficiently, using the trust and security of blockchain. Thus, VoteLink was born—a decentralized hub to improve student innovation.
