Bitcoin, Fiat & Rock'n'Roll

How SAP's Digital Currency Hub brings stablecoins into everyday enterprise software In this episode of Bitcoin, Fiat & Rock’n’Roll, we explore how SAP’s Digital Currency Hub (DCH) is bridging the gap between enterprise software and stablecoins. Michael Blaschke, Bernhard Schweizer (SAP), and Rebecca Carvatt (EY) explain how enterprises handle stablecoin payments without leaving their familiar ERP environment. We explore the technical architecture that allows for 24/7, instant, global payments at low fees, supporting major stablecoins like USDC and PYUSD across multiple blockchain networks. The conversation includes a detailed look at PayPal’s historic first business payment using PYUSD to pay EY in fall 2024, marking a significant milestone in enterprise stablecoin adoption. Our guests break down the practical aspects of implementation, from wallet management and currency conversion to compliance considerations and accounting standards. They share insights on why major corporations are embracing this technology now, particularly for cross-border payments and high-inflation corridors. The episode offers valuable guidance for corporate treasurers and finance leaders preparing for the future of payments, including specific action items for getting started with stablecoin payments in an enterprise context. The discussion concludes with a forward-looking perspective on the evolution of enterprise payments, including programmable finance, machine-to-machine transactions, and the growing ecosystem of companies adopting digital currency solutions for business payments. Listeners will come away with a clear understanding of how traditional finance is being transformed by the merger of enterprise software and digital currencies.

We discuss the potential drawbacks of Bitcoin Reserves with European Central Bank advisor Jürgen Schaaf Strategic Bitcoin Reserves remain one of the most intensely debated topics in the digital currency landscape. Just a few days back, US President Trump has signed an Executive Order that states the establishment of both a Bitcoin Reserve and a broader Digital Asset Stockpile in the US. In this new episode of the Bitcoin, Fiat & Rock’n’Roll (BFRR) podcast, host Jonas Gross explores the topic of Bitcoin Reserves with Dr. Jürgen Schaaf, advisor to the Senior Management at the European Central Bank (ECB). Following a previous episode that examined the pro-Bitcoin Reserve perspective, this conversation dives deep into the counterarguments. Dr. Schaaf points to Bitcoin's fundamental limitations. He argues that Bitcoin mainly failed to deliver on its original promise as a payment system, points to its extreme volatility as a barrier to mainstream adoption and questions its utility. The discussion distinguishes between three distinct reserve models that are often conflated in public discourse: strategic reserves, foreign exchange reserves, and sovereign wealth funds. Dr. Schaaf provides an analysis of whether from his perspective any of these three frameworks presents a legitimate economic case for institutions holding Bitcoin —with conclusions that may surprise listeners. After two comprehensive episodes on Bitcoin reserves—examining both the supportive and critical viewpoints—stay tuned for an upcoming episode where the BFRR team will thoughtfully reflect on these discussions and share their own perspective on this both controversial and timely topic.

Let’s dive into the most important news in February In this episode all four co-hosts, Alexander, Michael, Jonas and Manuel discuss the most relevant news of February: The negative crypto market sentiment, market cap and ETF AuM contractions and the reasons for that – among others the Bybit Hack Presidential Meme-Coins. On Feb 21, one of the largest Crypto-Exchanges was hacked and a north-korean hacking group stole 1,4 bln USD worth of cryptocurrencies. The co-authors explain what happened and discuss how the attack and the biggest hack in history could have been prevented. The Episode goes on to analyze and discuss the players and the mechanisms behind the issuance and price collapse of the Libra token that was supported by the Argentinian president Javier Milei and the interlinkage to the Melania Token. After the bearish news, the record 2024 earnings of Tether and Coinbase are analyzed which reflect the positive crypto sentiment and market activity of last year – in particular in Q4. The last section is devoted to European developments with an update on European MiCAR licenses for Stablecoins and crypto asset service providers as well as recent developments in the European projects on central bank digital currencies (CBDC). The ECB sees threats from USD denominated Stablecoins and wants to accelerate the digital Euro project as a respondes and on the other side wants to provide a solution in 2025 to connect Target services – existing settlement infrastructure – to newly emerging blockchain networks.

Will Quantum Computers Break Bitcoin? A Deep Dive into Crypto’s Biggest Security Challenge Quantum computing is no longer a distant prospect; it’s a reality. In this episode, co-host Michael Blaschke explores two significant developments that are impacting the relationship between quantum computing and blockchain: Google’s 105-qubit Willow chip and Ethereum’s proactive initiative for quantum resistance, known as "The Splurge." Based on insights from his recent study at the FERI Cognitive Finance Institute, titled "Quantenzeitalter: Quantencomputing als Gamechanger für Finanz- und Realwirtschaft," Michael discusses the implications of quantum computing for both traditional finance and the cryptocurrency sector. The episode simplifies complex quantum concepts, highlighting how quantum computing poses both challenges and opportunities for traditional finance and crypto. Key topics include: Understanding Google’s Willow chip and its breakthrough capabilities The fundamental differences between quantum and classical computing How quantum computers could theoretically break current cryptographic systems Bitcoin’s existing defense mechanisms against quantum threats The crypto community’s response and preparation strategies Vitalik Buterin’s vision for a quantum-resistant Ethereum Practical implications for investors, institutions, and developers Bitcoin, Fiat & Rock'n'Roll Website Bitcoin, Fiat & Rock'n'Roll Telegram Channel FERI press release “Quantum computing: game changer for a new information age” Michael’s analysis “Quantenzeitalter: Quantencomputing als Gamechanger für Finanz- und Realwirtschaft” published by FERI as a Cognitive Comment in German Recent post by Vitalik Buterin: “Possible futures of the Ethereum protocol, part 6: The Splurge" Google press release “Meet Willow, our state-of-the-art quantum chip” Research paper “Quantum Attacks on Bitcoin, and How to Protect Against Them” Relai*: Buy Bitcoin with Relai – you can do a one-time purchase or savings plan: Click here.

We explore why the FDP has included the Bitcoin reserve initiative in their election program The concept of a "strategic Bitcoin reserve" is gaining increasing international significance. What Donald Trump brought up in the US election campaign is now being seriously considered by a growing number of nations - including Brazil, Japan, Russia, and China alongside the US. The Czech Central Bank recently marked a milestone by becoming the first of its kind to officially announce plans to evaluate Bitcoin investments. Against this backdrop, the new episode of Bitcoin, Fiat & Rock'n'Roll focuses on whether and how nations and central banks should use Bitcoin as a strategic reserve - a topic now also taken up by the FDP in the current German federal election campaign. Co-hosts Jonas Gross and Michael Blaschke discuss this with FDP member of parliament Frank Schäffler, who champions Bitcoin, crypto, and digital asset topics in the Bundestag like few others. How does the FDP envision a Bitcoin reserve? The specific proposal suggests that the German Bundesbank and the European Central Bank (ECB) should diversify their currency reserves through Bitcoin. The Bundesbank's current gold reserves of 140 billion euros serve as a reference point. Schäffler emphasizes that this is a political appeal, as central banks remain independent in their investment decisions. Implementation would occur through active, systematic new acquisitions. Should the German state also buy Bitcoin according to the FDP's vision? You'll find out in the episode. What are the challenges? Schäffler sees the biggest challenges in convincing the "establishment" and central banks. While ECB President Lagarde currently rejects Bitcoin investments, Schäffler considers it progress that the topic is being discussed at this level at all. He points to the positive developments of recent years: from the first tax recognition in 2013 to today's broad social acceptance of Bitcoin. What other challenges exist? You'll find out in the episode. Enjoy the Episode!

An Introduction to zero-knowledge proofs: their potential, applications, and challenges In this episode of 'Bitcoin, Fiat & Rock'n'Roll' (BFRR), we explore zero-knowledge proofs (ZKPs), a technological innovation helping to protect privacy in our increasingly digital world. Co-host Jonas Gross discusses with Johannes Sedlmeir, postdoctoral researcher at the University of Luxembourg, how ZKPs work, their relevance, applications, and potential. They address key terminology and clarify common misconceptions. Johannes illustrates ZKPs through a simple cave analogy: Imagine being trapped in a cave with two exits and a door in the middle. As the prover, you want to demonstrate to a verifier that you can open the door by exiting on either side - without revealing how. The verifier requests you exit on different sides repeatedly. After multiple successful attempts, the verifier becomes convinced you possess the secret without ever seeing it. Johannes extends this explanation with practical examples for different audiences – e.g., adults and engineers. ZKPs have applications across numerous privacy-critical domains, including payments and identity, e.g., identification, authorization, and authentication. Recent technological advances have made many use cases practical today, while others face ongoing challenges. Which applications show the most promise and could reach billion-dollar market potential? The episode concludes with Jonas and Johannes discussing when ZKPs might become mainstream technology, operating quietly behind most digital processes. Tune in to hear their insights.
