I think the first question that comes up that's very obvious

So this word was kind of invented 10 years ago when--

I don't know how many of you know the origin story of where

bitcoin came from, but basically a pseudonym on the internet

dropped a paper and some open source code

in a forum on an email list, and said, hey,

I have this idea for this thing called bitcoin.

and here is some code if you want to run it and become part

This person has basically virtually disappeared

But it's created something that has captured

so many people's imaginations and has sort of, depending

and billions of dollars of economic value

and inspired a lot of people to think about how

to use this technology to solve a myriad of different problems,

So cryptocurrencies and the technology behind them

are inspiring people to think about how to bank the unbanked,

add more auditability and traceability to our world,

get rid of trusted intermediaries and institutions

in certain situations, and basically solve

every problem, if you read about what blockchains

Now that's not exactly what this class is about.

This class is not going to be about applications.

This class is going to be about technology and infrastructure.

You're going to learn how to create a cryptocurrency, what

goes inside a cryptocurrency, what's important,

And what application you choose to apply that to down the line,

But we're not going to be doing digital identity or health care

We're going to be talking about the technology.

So a big question is how are cryptocurrencies

And another thing that I want to make really clear

is that the terms in this space are still being defined.

all sorts of terms-- cryptocurrency, blockchain,

And these words kind of have floating, evolving meanings

Part of that is because bitcoin, the first cryptocurrency,

didn't come from academia, as far as we know.

It came from a community of enthusiasts on the internet.

And so it doesn't necessarily have the same basis and rigor

that we might expect from most of our academic fields

And academia is really embracing this topic.

So if any of you are graduate students who

are looking for an area in which to do research,

published on cryptocurrencies and blockchain technology

in respected academic venues is doubling every year.

So cryptocurrencies are not regular currencies.

Bitcoin was sort of created out of nowhere.

And what does it mean to create a cryptocurrency?

Who says you can create a cryptocurrency?

Well, first, before we answer that question,

If you are interested in ICO'ing, just go.

That's not what this class is going to be about.

We are not going to offer any trading advice.

We have zero opinions on whether you should buy bitcoin

to be about permissioned blockchains either.
