Luxembourg Zero Knowledge Days

26 - 27 June 2019

ZKP (Zero Knowledge Proofs) is a method to prove the knowledge of some fact, without revealing that fact. It is already used in several blockchains and is expected to have a major impact on applications that involve transactions, identity systems, and proprietary information in general.

The ZKLux#1 conference is now over, slides and videos are available below.
Thank you to all our speakers, sponsors and everyone who attended.



ZKLux#1 is barely over, but we are already looking ahead to the next edition. If you are interested to speak at a future ZKLux#2 conference, or to participate as a sponsor or partner, please get in touch with us!

About Sikoba Research

Sikoba Research Sàrl ( is a Luxembourg company incorporated in October 2018 with the purpose to conduct fundamental and applied research in the areas of cryptography, blockchain and distributed systems. It is a sister company of Sikoba Ltd ( which is developing an IOU platform on blockchain.


Sikoba Research is developing Isekai, a verifiable computation framework that will
allow to work with several programming languages and verifiable computation
systems while using a single code-to-circuit module.
Our goal is to make the use of ZK proofs and verifiable computing as easy as possible, especially for non-specialists.
