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.
