Lecture 4.4 – Online Wallets and Exchanges [Bitcoin and Cryptocurrencies]
 
19:28
In segment 4.4, we'll move on to talk about Online Wallets and Exchanges. Thus far, we've talked about ways in which you could store and manage your bitcoins yourself. Now we'll talk about ways in which you can use other people's services to help you do that. So the first thing you could do is to use an online wallet. An online wallet is kind of like a local wallet that you might manage yourself, except that the information is stored in the cloud and so you have some kind of say web based interface like this. This is from one called Block Chain, but there are plenty of other online wallet services.

Lecture 2.4 – Incentives and Proof of Work [Bitcoin and Cryptocurrencies]
 
19:48
So, in the previous section, we got a basic look at BitCoin's consensus algorithm and a good intuition for why we believe that it's secure. But recall that at the beginning of the lecture I told you that BitCoin's decentralization is partly a technical mechanism and partly clever incentive engineering. So far, we've mostly looked at the technical mechanism. Now let's talk about the incentive engineering that happens in BitCoin.

Lecture 2.1 – Centralization vs. Decentralization [Bitcoin and Cryptocurrencies]
 
04:48
Hello, and welcome to the second lecture, which is going to be all about decentralization in Bitcoin. Now, in the first lecture you saw a lot of the crypto basics that underlie Bitcoin and we ended with a simple currency that we called Scrooge coin. That seems to achieve a lot of what we want in a ledger based crypto currency, except for one big glaring problem, which is that it relies upon the centralized authority called Scrooge. And we end it with the question of, how do we de-scroogify this currency? How do we go to a decentralized version of this? That's what we're gonna see today. What I find cool about this is that the way in which Bitcoin achieves decentralization is not purely technical but it's a combination of technical and clever incentive engineering. And, at the end of this lecture, you should have a really good appreciation for how this happens asnd a lot of the magic or mystery of Bitcoin should become clear to you and how it works and why it's secure, and what makes it tick.

Lecture 6.5 – Zerocoin and Zerocash [Bitcoin and Cryptocurrencies]

Now let's turn to Zerocoin and Zerocash, which are a completely different approach to Bitcoin anonymity. The approach is to bake it in at the protocol level. And these are cryptographic heavyweights.

Why do bad passwords work in counterwallet?
 
02:47
Why is that when you type the 'wrong' password into counter wallet, you nonetheless proceed pass a login screen? Is this a bug in counterwallet, or is this the way it's supposed to work? In this video, shot in the Wynwood district of Miami, I discuss the basics of counterwallet, and how 'authentication' isn't quite what it seems.

How long do we have to fix the one megabyte block size?
 
04:26
Given all the drama around the block sizes increase in the Bitcoin community, it makes sense to ask the question of "What's the Rush?". Or better still, is there even a rush to begin with? @Pumpkinfeet posed this question on reddit the other day, and I felt it was a great question to kick off my coverage of the Miami Bitcoin Hackathon. In this video, I discuss Bitcoin, block sizes, and all things counterparty!

How will Counterparty be used for gaming?
 
04:06
With all the hype around finance, contracts, and "liberty", the video game industry is often overlooked. Nonetheless, the potential for efficiency in this industry is enormous, and probably one of the major venues that Counterparty should be targetting. In this video, shot from North Miami Beach, I discuss video games, Counterparty, and all things Bitcoin.
