In this fireside chat at Pragma Prague 2025, Kartik Talwar sits down with Friederike Ernst, co-founder of Gnosis, to explore Circles - a revolutionary approach to personal currencies. They discuss how Circles reimagines money creation using modern cryptography, eliminating banks as intermediaries while maintaining a web-of-trust model.
