Jens Groth is a cryptographer known for his work on pairing-based cryptography and zero-knowledge proofs. He received a PhD in computer science from Aarhus University, and was a professor at University College London. He later left the university to become the Chief Scientist at Neuxs.
Research
Groth's 2016 paper, On the size of pairing-based non-interactive arguments, described a succinct, noninteractive zero-knowledge proof scheme based on pairings, commonly referred to as "Groth16".[1] It is quite compact, with proofs consisting of just three group elements. The construction is used in several cryptocurrency protocols, such as Zcash and Tornado Cash.[2] A subsequent work by Helger Lipmaa showed that even smaller proofs are possible, reducing proof sizes from 1792 bits to 1408 bits for practical parameters.[3]
