A product recall today is basically a notice. It lives on a webpage, or a PDF, or an email that somebody is supposed to read. Say the problem out loud and it gets uncomfortable fast. A recalled crib can be listed and sold to another family, and nobody in that sale ever sees the recall. Reselling recalled goods is actually illegal, and recalled infant products have killed kids.
I spent this hackathon building something to close that gap. I called it SafeState, and the idea is small: make the recall do something. When a second-hand item is listed or sold, the marketplace checks SafeState first, and recalled units get blocked right at checkout. It is precise down to the serial number, so safe units still sell.
It runs on the stack this hackathon is about. A Next.js front end on Vercel, with Amazon Aurora DSQL behind it.
Why DSQL is the whole point here
