Plato's Cave - The Orlando Philosophy Meetup Group

Warm Greetings to All,

Join Plato's Cave philosophers and Orlando Stoics on Zoom this Sunday morning, May 24 at 9:00. (Informal chat at 9:00, forum at 9:15)

Plato's Cave members can reserve a place, receive zoom login information on this site and receive e-mail confirmation.

Every Sunday, a new forum. Our meeting starts at 9:00 AM with friendly wakeup chat; then our select topic panel briefly introduces the subject at 9:15, followed by member discussion and Q&A.
Volunteer introduction panelists will meet following each forum to develop the next program;.

This Sunday:
Exchange Without a Master

Last week we looked at three figures who found ways to lend money to people the banks had ignored. This week, we will explore what happens when people try to build money itself outside the reach of any government, bank, or trusted authority. The question is no longer who gets to borrow. It is who gets to make money in the first place. For most of history, the answer has been governments and the banks they license. The two figures we will discuss, along with one novel that shaped their world, asked a different question. What if money could rest on math instead of trust in people? And what would such a world actually look like?

David Chaum and Satoshi Nakamoto each saw money as something that could be redesigned from scratch. Each tried to remove the people in the middle and replace them with code. The promise was familiar: privacy, freedom, wider access, lower cost. So were the problems. Speculation, fraud, heavy energy use, and a new kind of wealth concentration followed.
We begin with David Chaum, the American cryptographer who imagined digital money long before it was possible to build. In the early 1980s at Berkeley, Chaum invented something called the blind signature. It let a bank approve a payment without knowing who was making it. In 1989 he founded DigiCash and built eCash, the first working system of digital cash that used cryptography to protect users. The first online payment was made in 1994. The technology worked, but the business did not. Banks were cautious, the public was not ready, and DigiCash went bankrupt in 1998. Yet nearly every important idea behind Bitcoin came from Chaum first. He insisted that money on the internet had to be private by default, or it would become a tool of surveillance. The question then becomes what kind of freedom is possible in a world where every payment can be watched?

Between Chaum and Satoshi, the dream of digital money lived less in code and more in fiction. Neal Stephenson's 1999 novel Cryptonomicon imagined a near future in which cryptography, gold-backed digital currency, and offshore data havens would together let people move money beyond the reach of governments. The novel grew out of the cypherpunk culture around Chaum's work and was read closely by many of the people who later built Bitcoin. It is worth considering that the desire for privacy and a wall between money and the state did not start with Bitcoin. It had been growing for decades in cryptography labs, online mailing lists, and novels.

We then come to Satoshi Nakamoto, the unknown person or group who published the Bitcoin white paper in 2008. Satoshi solved a problem that had defeated everyone before, including Chaum. A digital currency without a central authority needed a way to stop the same coin from being spent twice, but without trusting anyone in particular to keep the records. The answer combined cryptography, economic incentives, and a public ledger maintained by anyone who wanted to help run the network. Bitcoin launched in January 2009. By 2011 Satoshi had walked away and has not been heard from since. The disappearance is not an accident. By refusing to be a person, Satoshi made sure the system would not depend on any one authority. Can trust really be replaced by math? Is a financial system with no one at the center more honest, or just more fragile?

Each individual tried to design a financial system that rested on code instead of people. Each believed that money had become too tied up with power, surveillance, and central control. Each saw his work caught up, in time, with speculation and new forms of concentration. Stephenson, writing fiction, helped shape the imagination in which they both worked. The questions for us are old ones in new clothes. Can math carry the moral weight we have always asked human institutions to carry? What do we gain, and what do we lose, when we try to replace the authority of people with the authority of code?
