Zero Knowledge

Where we talk about zero knowledge research and the decentralised web

About the show

Zero Knowledge is a podcast which goes deep into the tech that will power the emerging decentralised web and the community building this. The podcast is made for fellow developers and people looking to educate themselves on the inner workings of the space.

We are non-speculative and focus on the tech.

    In this episode, we catch up with Vishwanath Raman, Privacy Architect at Oasis Labs. Oasis is a privacy-enabled blockchain platform for responsible data use. Using a combination of secure computing and privacy technologies, the Oasis Network enables data owners to take control of their data and treat their data as a digital asset via data tokenization. They provide privacy as a service and use secure enclaves and differential privacy in order build a platform for a responsible data economy.

The project enables private applications with both data privacy and functional privacy - where the nature of the program running and all activity remains private. It is based on the ZEXE protocol and Proof-of-Succinct-Work.
