TODAY'S SHOW: This episode of Monero Talk features the CypherStack team — CEO Diego Salazar and mathematicians Brandon “Surae” Goodell and Luke — for a deep dive into Monero’s Full Chain Membership Proofs (FCMPs) and how they compare to Zcash.

CypherStack is a privacy-focused research and development company behind Stack Wallet. Diego handles strategy while Brandon and Luke lead the mathematical research for Monero. They discussed their contributions to FCMPs, a major upgrade aimed at improving Monero’s privacy and scalability. While critics from the Zcash community call FCMPs “unproven,” the team explained that it uses well-established mathematics, not untested theory.

They also compared Monero’s community-driven model with Zcash’s corporate structure, noting strengths and trade-offs in both approaches. Despite praising Zcash’s Halo 2 privacy tech, they argue Monero’s privacy-by-default design gives it a real-world edge.On timelines, Diego said FCMPs are “three steps from the finish line” but still tackling technical challenges. The episode ends with a candid look at funding struggles in open-source development and a call for continued community support.

TODAY'S SHOW: In this episode of Monero Talk, Douglas Tuman chats with Diego Salazar (Rarar) and Luke Szramowski from Cypherstack about Full Chain Membership Proofs (FCMPs), a breakthrough that will dramatically boost Monero’s privacy. 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.
