Day 1 — Why does crypto exist?

In the autumn of 2008, the global financial system was about two weeks from collapse. Lehman Brothers had filed for bankruptcy. The U.S. government had nationalized AIG, the largest insurer in the world, with an $85 billion emergency loan. The commercial paper market, the plumbing that lets Fortune 500 companies make payroll, froze. Money market funds, which most Americans had been told were "as safe as cash," broke the buck for the first time in fourteen years.

In Washington, Treasury Secretary Hank Paulson was, by his own admission, on his knees asking Nancy Pelosi for a bailout.

On October 31 of that year, while all of this was still unfolding, an anonymous person posting under the name Satoshi Nakamoto published a nine-page paper to a cryptography mailing list. The paper described a peer-to-peer electronic cash system. Embedded in the very first block of the network, which went live in January 2009, was a single line of text:

"The Times 03/Jan/2009 Chancellor on brink of second bailout for banks."

That is the origin. Bitcoin wasn't designed because someone thought programmable money sounded cool. It was designed because someone watched the entire global financial system require trillions of dollars in taxpayer bailouts to avoid imploding, and concluded that the problem wasn't really the bankers.

The problem was the system itself.

Any system that depends on trust in centralized intermediaries will eventually fail. And the failure will be expensive for everyone who isn't a banker.

The technical innovation in Satoshi's paper was real, and we'll spend most of the next month unpacking it. But the more important thing was the framing. Money, the thing we use to coordinate value across our entire lives, had been almost entirely a question of who do you trust. You trusted your bank not to lose your deposits. You trusted the government to back your dollars. You trusted Visa to settle your card transactions. You trusted SWIFT to wire your money. You trusted Western Union not to fleece you when you sent money to family abroad.

What Satoshi proposed was that none of that trust should be necessary. With cryptography, with a clever incentive mechanism called proof-of-work, and with a public ledger anyone could verify, you could have money that didn't depend on any of those institutions. The line everyone quotes from the paper is "without going through a financial institution." If you wanted to send value to anyone in the world, you could.

That was the original problem, and it had nothing to do with how crypto would later get sold. It wasn't framed as an investment opportunity, marketed as speculation, or pitched as an alternative asset class. The problem was that the global financial system requires trust in intermediaries that have repeatedly proven not to deserve it. And the question was whether we could build money that doesn't.

Seventeen years later, this is where the conversation should still start. Because everything else flows from this.

Stablecoins exist because billions of people don't have reliable access to dollars. DeFi exists because credit markets are gatekept in ways that benefit the gatekeepers. Tokenized real-world assets exist because property records, ownership, and reporting are still mostly trapped in nineteenth-century paper systems. Even NFTs, in their less ridiculous form, exist because no one had figured out a clean way to prove digital ownership at all.

You can disagree with whether crypto has actually solved any of these problems. Plenty of thoughtful people do, and we're going to look at the strongest version of those arguments later in this course. But to evaluate the question fairly, you first have to understand what it was trying to solve.

That is where we start. The next 29 days are going to give you the tools to make your own call on all of it: whether crypto has delivered on the original promise, whether the next decade of capital allocation runs on the rails being built right now, and whether you are going to be early enough to position yourself for what comes next.

You showed up here for a reason. Let's go figure out what it is.


Glossary

Inline tooltips on bold terms above. Quick-scan table below. Master glossary at impctinstitute.com/glossary.

TermDefinition
BitcoinThe first cryptocurrency, launched in January 2009 by an anonymous developer or group using the name Satoshi Nakamoto. Designed as peer-to-peer electronic cash that doesn't require a financial intermediary.
CryptocurrencyA form of digital money that uses cryptography to secure transactions and is recorded on a blockchain rather than in the books of a central institution.
BlockchainA shared, append-only ledger maintained by a distributed network of computers rather than by a single authority.
CryptographyThe mathematical techniques used to secure information. In crypto, primarily public-key cryptography (which lets users prove ownership without revealing secrets) and hashing (which fingerprints data).
DecentralizationThe property of a system in which no single party can unilaterally change the rules or block participation.
Double-spend problemThe challenge of preventing someone from spending the same unit of digital money twice. Solved by Bitcoin without needing a central authority.
Proof-of-workThe mechanism Bitcoin uses to decide whose transactions get added to the ledger. It requires real computational effort, which makes attacks expensive.

Reality check (not a quiz)

Hold this in your head. If you can answer it, you got what today was for. If you can't, that is useful information. Go back to the section that covers it.

Before crypto existed, who was responsible for making sure the dollar in your bank account was actually still there? And what could go wrong if that responsibility wasn't met?

If your first answer was "the bank," go deeper. If your answer included something like "the bank, but the bank only holds a fraction of what it owes me, and the government insures up to $250K, and the whole system works as long as everyone doesn't try to withdraw at once," you're tracking.

The point of this is not to get it right on the first try. The point is to notice where your understanding is sharp and where it's still fuzzy. The fuzziness is the data. That is where the learning happens.

1. Bitcoin: A Peer-to-Peer Electronic Cash System by Satoshi Nakamoto (2008)

The original whitepaper. Nine pages. The seed of everything.

Read on IMPCT (curated commentary) | Read original (bitcoin.org)

Deven's take. You can spend your whole life talking about crypto without ever reading this. Most people do. Don't be most people. The abstract and section one are enough to understand the original framing, and the math doesn't matter for what we're doing here. The clarity of intent does. Notice how every design decision in the paper flows from the same conviction: trust no intermediary. That is the seed of everything you are going to see over the next 29 days. Pay attention to the tone too. It is direct, technical, unembellished. The most consequential financial document of the last fifty years was written like a homework assignment.

2. The Crypto Story by Matt Levine (Bloomberg, 2022)

40,000 words. The best long-read on what crypto is and what has been built on it.

Deven's take. If you read one supplemental piece during this entire course, make it this one. Levine is one of the few financial writers who is fair to crypto without being a fanboy. He gets the technology right and is brutal about the parts that don't work. He took about a year to write it. You can probably knock it out over a long weekend. It will make every news headline you read for the next two years make more sense, and it will save you from the two failure modes most people in this space have. The first is dismissing crypto entirely because they got burned in 2022. The second is believing every coin is the next Bitcoin. Levine helps you avoid both.

3. Why was Bitcoin created? by The Block (2024)

A condensed origin recap with more on the cypherpunk movement that preceded Satoshi.

Read on IMPCT (curated commentary) | Read original (theblock.co)

Deven's take. If the whitepaper feels too dense, start here. It gives you the political and philosophical lineage Bitcoin came out of. Worth knowing: the people who built the foundation of crypto were not finance bros. They were cryptographers, privacy advocates, and academics who had been arguing for decades that strong cryptography was going to change the relationship between individuals and institutions. They were right. The fact that Wall Street showed up later is a feature of the technology, not a contradiction of its origin.

4. The Crypto Anarchist Manifesto (Tim May, 1988) and A Cypherpunk's Manifesto (Eric Hughes, 1993)

The philosophical precursors. Both short. Both ahead of their time by decades.

Read on IMPCT (curated commentary) | Read originals (activism.net)

Deven's take. These two essays were written before most of the people now buying Bitcoin ETFs were even born. They argued, decades ahead of the technology, that the rules were going to change. Read them not because they predict Bitcoin specifically. Read them because they show you what it looks like when someone sees the future before the future sees itself. That is the muscle you are building in this course. We are not training you to be early to a trade. We are training you to recognize the shape of the next system while most people are still arguing about the current one.

5. The Sovereign Individual by James Dale Davidson and William Rees-Mogg (1997)

A book recommendation. Three decades old. Predicted most of what is happening right now.

Deven's take. Park this one for later. Not for this week. It is a longer commitment and it is also genuinely uncomfortable to read in 2026 because the authors got too much of it right. They wrote in 1997 that strong cryptography plus the internet would rearrange the relationship between citizens, governments, and capital in ways that would benefit the technically literate and disadvantage everyone who refused to adapt. Twenty-nine years later that is a fair description of what is unfolding. Read it when you are ready to think about your own positioning, not just the technology.


Tomorrow

We go one level deeper on the mechanism. What is a blockchain, really? You have probably heard the analogy that a blockchain is a shared spreadsheet that nobody owns and nobody can secretly edit. Tomorrow we figure out why that is mostly right, where it breaks down, and why this particular trick was unsolvable for forty years before Satoshi solved it.

See you in the morning.
