Diego, a longtime Monero contributor and founder of Cypherstack, discusses Stack Wallet—an open-source, multi-platform wallet for privacy coins—and stresses the importance of user-friendly design in privacy tech. The conversation dives into FCMPs, which will expand Monero’s anonymity set from around 16 to potentially every transaction ever made, with only a logarithmic increase in size. Luke, a mathematician and cryptographer, details the recent hurdles involving 'divisors'—key components that improve FCMP efficiency—and how they overcame complex security challenges to develop a secure version now under review by the Monero Research Lab. Diego ranks privacy levels across cryptocurrencies, placing current Monero at a 1, Firo’s Lelantus Spark at 4, and Zcash’s Halo 2 Orchard at 10. With FCMPs, he believes Monero could reach 9 or 10—on par with Zcash. The discussion also covers post-quantum cryptography as the next big frontier, with Cypherstack already exploring solutions. Despite earlier setbacks, FCMP development is back on schedule, targeting a Q1 2026 deployment pending code compatibility checks led by MRL’s Justin Ehrenhofer.

Om Podcasten

Monero Talk broadcasts weekly conversations on YouTube (https://www.youtube.com/c/monerotalk) with topical guests to understand what the Monero cryptocurrency is today and what it hopes to become. We strive to give birth to new Monero users by simply reporting on the facts in our search to answer the question--Is Monero the truest cryptocurrency of them all? In staying true to the Monero ethos, we aim to always be skeptical. While we are Monero Talk by name, and Monero devotees at heart, the intention of the show is to ultimately discover and support the one blockchain that is most aligned with the original cypherpunk and crypto-anarchist ideals that cryptocurrency was born from. And the one that is most likely to succeed at becoming true digital cash. So far, we believe Monero is the one. Guests include: The developers and researchers working on the open source core protocol and the cryptography behind it; The people building the projects and infrastructure supporting the protocol; Privacy advocates and people building privacy enhancing technologies; Analysts and investors speculating on Monero's growth; Journalists and pundits weighing in on Monero's place in the crypto-sphere; and Respected (sometimes controversial) contributors and community members. If you enjoyed the show & would like to support us, a donation of any size would be greatly appreciated and would mean so much!
