I strongly endorse and recommend this course. Ignore the coding assignments :) Click here and take the course! https://www.coursera.org/learn/cryptocurrency/supplement/M3c6U/course-information ------------- ABout the Course from Coursera ------------------------- Welcome to Bitcoin and Cryptocurrency Technologies! https://www.coursera.org/learn/cryptocurrency/supplement/M3c6U/course-information You’re joining over 150,000 other learners currently enrolled in the course. I'm excited to have you in the class and look forward to exploring Bitcoin, cryptocurrencies, and blockchains with you. This course includes three programming assignments, in addition to lectures and quizzes. Doing these assignments will enhance your understanding of the material, but you can get a lot out of the course even if you don’t have a programming background. The course site treats assignments as mandatory, but you should consider them as optional. Either way, the course doesn’t offer a certificate for passing, per Princeton University policy. We encourage you to use the textbook, Bitcoin and Cryptocurrency Technologies, as a complement to this course. The textbook chapters closely follow the lectures but feature additional detail and/or alternative explanations of many tricky concepts. A free draft is available also, but the published version is more polished, professionally edited, and peer-reviewed. I recommend taking a few minutes to explore the course site and reviewing the material we’ll cover each week. Click Discussions to see forums where you can discuss the course material with fellow students taking the class. Feel free to introduce yourself to everyone in the Meet and Greet forum.

Blockchain technology is hot right now! I've devised a 2 month study plan to help you learn how blockchains and cryptocurrency works. This is the kind of curriculum I'd create for myself to learn, but I'm open sourcing it for you guys since I love you. We'll start with cryptography, move on to Bitcoin, then Ethereum, other cryptos, and finally Decentralized Applications.

Lecture 6.5 – Zerocoin and Zerocash [Bitcoin and Cryptocurrencies]
 
19:48
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.

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 1.5 – A Simple Cryptocurrency [Bitcoin and Cryptocurrencies]
 
14:05
In segment 1.5, we're going to move from talking about Cryptography and we're going to move on to Cryptocurrencies. Now, I know that many of you showed up here for the Cryptocurrency stuff. And, trust me, there will be a lot more Cryptocurrency material in future lecture. Unfortunately we needed to eat some of our cryptographic vegetables in order to have the background to talk about Cryptocurrencies. And now you'll see when I start talking about Cryptocurrencies how these pieces fit together and why the cryptographic operations like hash functions and digital signatures are actually useful. All right, so in this section I want to talk about some simplified Cryptocurrencies that give us ideas about how systems like BitCoin work. Of course, it's going to require about ten more lectures in order to really spell out all of the implications of how BitCoin works and what that means. But let me talk about some very simple Cryptocurrencies to get the discussion started.

Welcome to the third lecture in our series on Bitcoin. This lecture is going to be all about the mechanics of Bitcoin at a fairly low level. So whereas in the first two lectures, we've talk in a relatively high level, in this lecture, we're going to be trying to give it to you as real as possible. So we'll look at real data structures, real scripts. Try to learn the details and language of Bitcoin in a precise way to set up everything that we wanna talk about for the remainder of the course. So in some ways, this will be the most challenging lecture because a lot of details are going to be flying at you.

Lecture 2.5 – Putting It All Together [Bitcoin and Cryptocurrencies]
 
18:06
Let's now look at mining economics, because we've said that it's quite expensive for miners to be in operation, because finding a single block takes computing about 10 to the 20 hashes. At the same time, we've also seen that the block reward is about 25 Bitcoins, which is quite a lot of money. So it really boils down to an economics question of whether or not it's profitable for a miner to mine.

Lecture 2.2 – Distributed Consensus [Bitcoin and Cryptocurrencies]
 
13:08
So we've talked in a generic manner about centralization and decentralization. Let's now talk, at a bit more technical level, about Bitcoin and decentralization. And a key word that's gonna come up again and again here is consensus, specifically distributed consensus. So what am I talking about here? At a technical level, the key challenge that you have to solve to build a distributed e-cash system is called distributed consensus. And this is a class of protocols that's been studied for decades in the computer science literature. So, but intuitively, you can think of it as our goal being to decentralize ScroogeCoin, which is the hypothetical currency that we saw in the first lecture.

Lecture 6.1 – Anonymity Basics [Bitcoin and Cryptocurrencies]
 
26:43
Hello and welcome the sixth lecture. By now you've seen a lot of the basics of Bitcoin, how the system works, how mining works, and how to use Bitcoin as a currency. Now let's get to what has been one of the most controversial aspects of Bitcoin which is the Anonymity properties of Bitcoin. And in fact there's a lot about Bitcoin and anonymity that you'll hear different opinions on. It's Bitcoin anonymous first of all? Are anonymous cryptocurrency is even a good thing? Is it good for people who have a stake in Bitcoin? Is it good for society? And what are the various proposals that have been made to improve Bitcoin's anonymity?

Lecture 3.3 – Applications of Bitcoin Scripts [Bitcoin and Cryptocurrencies]
 
14:50
So we've just invested the effort to understand Bitcoin scripts a little bit, but I haven't really shown you what's so cool about Bitcoin scripts yet. It turns out, you can do quite a lot of neat things that will justify the complexity of having the scripting language instead of just specifying public keys.

The miners are interested in finding a nonce which will create a hash with certain characteristics. Lastly, they have to find a random value that they included in the header, which makes the computed hash over that header a value below a particular target. In other words, they do not have to agree to change the protocol. Though there are a few gold diggers attempting to fill their pockets and certain projects that aren`t viable and shouldn`t be encouraged in any way. For users running a complete node, it is a fairly painless procedure to upgrade the software to the newest version. The process of locating a new block to extend the blockchain is known as mining. Proof-of-Work systems utilize cryptographic hashing algorithms to create the action of mining a block a complicated computation. Our software is totally incompatible with altcoins. Changes and modifications to how that it works need to be approved by consensus and every CPU gets a vote. To start with, it`s essential to realize that hardware wallet users control entirely their private keys. Whether you`re bullish or bearish on Bitcoin Gold, you ought not lose your coins as a result of careless mistakes! On the 1 hand, it may result in making a coin that solves all the pending issues.

If you have some concerns about the worth of Bitcoin after all forks, you need to be ready for a drop. The distinction is that not all of these suffer the chain split. The primary problem is Bitcoin imposes a hard limit on the magnitude of a block, the location where transaction information becomes stored. The end result is many straightforward wallets, called SPV wallets and very commonly found on your phone, will be quite confused about which chain is Bitcoin. In Bitcoin, the most important reason is known as the network effect.
