Being able to 100% reliably authenticate the identities of any user on the internet sounds like a dream come true, right? Imagine a world where no accounts get “hacked” and impersonation doesn’t exist. But wait! Allowing companies to obtain your full identity means enabling them to trace and track your every move is about as appealing as finding a mosquito in your bedroom at 2 AM. In this talk, we’ll dive into the paradox of linkability for electronic identities. We’ll explore current solutions trying to save the day—and the shortcomings that make them more like mild inconveniences. Then, we’ll unveil future advanced strategies using Zero Knowledge Proofs (ZKPs) that could lead to untraceable digital identities worthy of a spy movie. Plus, we’ll share some tales of the hurdles faced when blending modern cryptography with the complex bureaucratic dance of EU regulations.
