Explore why sound money preserves purchasing power and why hard money resists debasement. Compare government paper currency as unsound money to gold as historically sound money.
Explain how gold's salability improved through layer two innovations, coins and IOUs, reducing transmission costs and enabling scalable, time- and space-efficient money transfers via goldsmiths.
Learn how gold-backed IOUs improve money by enabling transferability without increasing the money supply, using a 100% gold reserve to preserve a 10% claim on productive capacity.
Explore how proto banks facilitated lending between individuals, with goldsmiths as mediators, earning fees while lenders bear risk and the money supply remains unchanged.
Explore how central banks regulate banks, issue a unified currency, and act as lender of last resort to stabilize monetary systems, shaping base and broad money.
Analyze how the Federal Reserve and central banks funded World War I through debasement, broke the gold standard, and fueled inflation, leading to the Great Depression and stock market crash.
Examine executive order 6102 during the Great Depression, forcing gold surrender to the Federal Reserve and the Gold Reserve Act that devalued the dollar, underscoring private property and natural rights.
Explore why governments seek control over money via Keynesian economics to smooth booms and busts, using deficits, surpluses, and money creation to gain political power.
Bretton Woods established a fixed exchange rate system with dollars backed by gold and reserves, creating the IMF and World Bank to support global cooperation, reconstruction, and development loans.

Bitcoin's hardness comes from needing to convince everyone across diverse communities to adopt changes, making updates slow, controversial, and driven by activation blocks and forks.
We currently live in an era of economic paradoxes that have left an indelible impact on our daily lives.
Interest rates have soared more than tenfold within 18 months, yet the stock market continues its relentless ascent, while inflation refuses to abate. The younger generations find themselves in a particularly precarious situation today. Despite both adults in a home often holding highly qualified jobs, the dream of a comfortable life with a house and children seems increasingly elusive to an ever larger number. This reveals a widening wealth gap in today’s economy despite the advent of technology that has exponentially increased productivity.
Behind these contradictory observations lies a new monetary context. Between 2021 and 2024, the US deficit ballooned from $27 trillion to $34.4 trillion, marking an almost 25% increase in less than four years. This unprecedented surge in the deficit clearly reveals an acceleration of a tendency that had slowly started in the seventies and that has significantly accelerated after 2009.
At the heart of all of this lies a fundamental tool and technology we all use and interact with every day: money. Our money, the currency we use every day, was also transformed in 1971, a date that marks the beginning of an increasing deficit trend. Interestingly, amidst the turmoil of the 2008 financial crisis, which was the largest of its kind, a mysterious and anonymous individual introduced a new type of money to the world, Bitcoin. A money that was designed and introduced as a way to address the weaknesses and limitations of the new type of money we started using in 1971, FIAT, and the unusual economic paradigm we find ourselves in today. As we navigate these uncertain times, it will be fascinating to see the role Bitcoin, the original and dominant cryptocurrency, will play in shaping our economic future, but in order to understand our current economic context, it is necessary to understand the relationship between money, inflation, the deficit, and Bitcoin.
This course is divided into two parts, examining the history and evolution of money from ancient times to the modern day. The first part will delve into what constitutes money, its failures throughout history, sound principles for a stable currency system, and how paper-based fiat currencies emerged as a replacement for gold-backed standards.
In the second half, we'll turn our attention to exploring a solution, Bitcoin, to the current problems plaguing fiat systems, including inflation, debt, housing bubbles, stock market volatility, and more. This is the First Cryptocurrency, and that relied on - among other technologies - blockchain that was created and is also the largest Crypto by Market Cap. We will explore Bitcoin's design principles, governance model in its decentralized network, and how it can function as a medium of exchange, unit of account, and store of value. Additionally, we'll examine the unique relationship between Bitcoin and energy grids, assess its potential as an investment opportunity, discuss security concerns related to hacking and regulation, and address common criticisms (FUD) surrounding Bitcoin's adoption.
