Cryptographer Matthew Green builds ring-signature Tor drop box to verify homework in the AI-agent era
matthew_d_green · x · 2026-09-06
Cryptographer Matthew Green (Johns Hopkins) describes the system he built to handle students submitting AI-agent-written homework: a cryptographic protocol using linkable ring signatures plus a Tor hidden service acting as a drop box, so submissions can be authenticated and students can prove they submitted without revealing their identity. He's unsure if it will work — he'd rather students just learn to code — but doesn't mind agents being used and wants to see if real learning is still possible.
