## Description

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.

The conversation covers practical implementation, group currencies, liquidity challenges, and real-world adoption strategies for this alternative monetary system that puts currency issuance directly in users' hands.
