Blockchain is often hyped as the future of everything from finance to voting, but I've yet to see a real-world use case where it clearly beats a traditional centralized database. I've spent the last three years working on supply chain tracking, and every pilot project we evaluated ran into scalability and cost issues that made the old system look better. The only domain where blockchain seems genuinely superior is cryptocurrency, and even there, the environmental and regulatory costs are hard to ignore. So, is blockchain actually solving a problem that couldn't be solved more simply, or are we just enamored with the technology?
