How zero-knowledge proofs can make AI fairer

Opinion by: Rob Viglione, co-founder and CEO of Horizen Labs

Can you trust your AI to be unbiased? A recent research paper suggests it’s a little more complicated. Unfortunately, bias isn’t just a bug — it’s a persistent feature without proper cryptographic guardrails.

A September 2024 study from Imperial College London shows how zero-knowledge proofs (ZKPs) can help companies verify that their machine learning (ML) models treat all demographic groups equally while still keeping model details and user data private.
