I found Koveh Development Studio. I create applications, APIs, websites, and telegram bots. I create projects for myself, teammates, and clients. I work at KPMG, and I am not allowed to get money by selling software to someone, therefore all my projects are currently either free of charge or with a not-for-profit subscription.

Why is it interesting

Every project is published at koveh.com, with the process shown, and the pitfalls described. It is helpful people, who want to know more about programming: the difficulties, the process itself, and most importantly: how much time and money should you spend on a project.

What to read #7: Money

Money: An Unofficial Biography of Money by Felix Martin

Restored by restorephotos.io

When I was 15, I received a¬†gift from my best friend, Max‚ÄĒa¬†book that would shape my understanding of¬†money. From that day on, my friends knew that books were the¬†way to¬†my heart.

Yap Island’s Unique Currency: Giant Stones and a Trust-Based Economy

In the remote Yap Island, found a hundred years ago, an extraordinary monetary system thrived. The inhabitants used enormous coin-like stones with holes in the center, known as Rai stones, as a form of currency. These stones were immovable, some as large as cars, and were quarried from distant islands and transported with great effort.

What made this system work was an intricate web of trust and communal understanding. Ownership of the stones could change without them physically moving. If someone wished to buy something, like 10 kilograms of fish, they would simply declare the transfer of ownership to the fisherman. Everyone in the community would acknowledge the new ownership and the transaction was complete.

The stones didn’t even need to be seen to hold value. In one legendary tale, a Rai stone was lost at sea during transport, but the community continued to recognize its value, and it remained part of the island’s currency system.

This unique approach to money, rooted in social trust and shared belief, challenges conventional economic thinking and provides a fascinating glimpse into how value can be ascribed and exchanged in diverse cultures.

The Birth of Forwards and Futures: Lyon, 1535

In the bustling market town of Lyon, France, in 1535, an extraordinary transformation was taking place. Amidst the cacophony of sellers peddling meats, fruits, and tools, one man stood out. He had no physical products, just a fountain pen, paper, and an idea that would revolutionize trading.

This man began selling the future by signing contracts to buy wheat at predefined prices and reselling them at higher rates. This practice, known as Forwards or Futures, was a radical departure from traditional commerce. It attracted attention, skepticism, and eventually imitation. Other traders started following suit, and soon, Lyon’s market was flooded with these future contracts.

The city’s reputation grew, attracting merchants and financiers from far and wide. Banks and financial institutions took notice, and Lyon became a hub for innovation in finance. By the end of the century, it was not only France’s financial center but also the heart of Europe’s burgeoning capital market. The man with the fountain pen had set in motion a wave that would eventually shape modern stock markets.

Eric’s Adventure: Risk, Profit, and the Birth of Joint-Stock Companies

Across the sea, in the small but ambitious trading nation of the Netherlands, a Dutch trader named Eric had a vision. He dreamed of building ships to explore and trade with distant lands, but his ambition was larger than his credit. Banks and friends lent what they could, but it was never enough.

Undeterred, Eric took a novel approach. Instead of seeking credit, he asked investors to buy a share of his profits. This was a new concept, and it attracted adventurous and like-minded individuals who saw the potential in overseas trade.

Eric’s first voyage was a resounding success, bringing in profits that exceeded all expectations. Word spread quickly, and more people clamored to invest in Eric’s next expedition. His fleet grew, and so did his reputation.

However, managing the growing number of investors became a Herculean task. There were disputes over ownership, profits, and investment terms. The government, too, struggled to track who owned what and how much tax was due.

The¬†solution was as¬†innovative as¬†Eric‚Äôs trading model‚ÄĒa¬†centralized exchange where shares in¬†his ventures, and¬†those of¬†his competitors, could be bought and¬†sold. This was the¬†genesis of¬†the¬†joint-stock company and¬†the¬†stock market, concepts that would define global commerce for¬†centuries to¬†come.

With each new voyage, risks and rewards were shared among an ever-growing pool of investors. The idea spread across Europe, laying the groundwork for modern corporations and investment structures. Eric’s vision had not only opened new trade routes but also charted a course for the future of business and finance.

John Law: The Gambler Who Shaped France’s Monetary System

John Law, a charismatic Scotsman, was a gambler, banker, and economist whose ideas would leave an indelible mark on France’s monetary system. Sentenced to death in Britain for killing a man in a duel, Law escaped to Europe, where his financial acumen caught the attention of France’s regent.

France was in financial ruin after years of war, and Law proposed a radical solution: replace gold and silver with paper money backed by land. He believed this would stimulate the economy and reduce the national debt.

In 1716, Law founded the Banque Générale, issuing paper money that could be exchanged for coins. His ideas were initially successful, and Law’s influence grew. He took over the Mississippi Company, controlling French trade with the Americas, and his paper money fueled a speculative bubble.

However, Law’s success was short-lived. Doubts about the real value of the paper money led to a loss of confidence, and the bubble burst. Law was forced to flee France in disgrace, his innovations leading to financial chaos.

Yet, despite the catastrophic end, Law’s ideas were ahead of their time. He foresaw the potential of a centralized banking system, fiat currency, and the complex interplay of economics and psychology. His story is a cautionary tale about innovation, ambition, and the fragile nature of economic systems, but also a testament to the power of ideas to shape history.

These expanded sections provide a more comprehensive view of the unique currency system of Yap Island and the complex story of John Law. By delving into the details, the narrative paints a vivid picture of these historical phenomena, offering readers a deeper understanding of the diverse and often surprising world of money.

Beyond the Stories: A Rich Exploration of Money

‚ÄúMoney: An¬†Unofficial Biography of¬†Money‚ÄĚ by¬†Felix Martin goes beyond the¬†fascinating stories of¬†Yap Island, Lyon, Eric‚Äôs adventures, and¬†John Law. It dives into the¬†complexities of¬†debt, the¬†art of¬†printing money (seigniorage), the¬†ideologies of¬†capitalism and¬†communism, the¬†evolution from the¬†gold standard to¬†fiat currency, and¬†the¬†prominence of¬†the¬†U.S. dollar.

This article was edited by¬†ChatGPT, which assisted me in¬†crafting the¬†storytelling, paraphrasing sentences, and¬†verifying facts from both the¬†book ‚ÄúMoney: An¬†Unofficial Biography of¬†Money‚ÄĚ by¬†Felix Martin and¬†my own memory. The¬†collaboration has helped shape a¬†more engaging and¬†accurate representation of¬†the¬†book‚Äôs rich exploration of¬†money and¬†its multifaceted history.
