To really understand what is special about Bitcoin, we need to understand how it works at a technical level. How does Bitcoin work? What makes Bitcoin different? How secure are your Bitcoins? How anonymous are Bitcoin users? What determines the price of Bitcoins? Can cryptocurrencies be regulated? What might the future hold? It does not offer a certificate upon completion. It is one of the eight universities of the Ivy League, and one of the nine Colonial Colleges founded before the American Revolution.
Learn about cryptographic building blocks "primitives" and reason about their security. Work through how these primitives can be used to construct simple cryptocurrencies. Learn Bitcoin's consensus mechanism and reason about its security. Appreciate how security comes from a combination of technical methods and clever incentive engineering. Learn how the individual components of the Bitcoin protocol make the whole system tick: transactions, script, blocks, and the peer-to-peer network.
This week we'll explore how using Bitcoins works in practice: different ways of storing Bitcoin keys, security measures, and various types of services that allow you to trade and transact with bitcoins.
We already know that Bitcoin relies crucially on mining. But who are the miners? How did they get into this? How do they operate? What's the business model like for miners? What impact do they have on the environment?
Is Bitcoin anonymous? What does that statement even mean—can we define it rigorously? We'll learn about the various ways to improve Bitcoin's anonymity and privacy and learn about Bitcoin's role in Silk Road and other hidden marketplaces. We'll look at all the ways that the world of Bitcoin and cryptocurrency technology touches the world of people. We'll discuss the community, politics within Bitcoin and the way that Bitcoin interacts with politics, and law enforcement and regulation issues.
Not everyone is happy about how Bitcoin mining works: its energy consumption and the fact that it requires specialized hardware are major sticking points.
This week we'll look at how mining can be re-designed in alternative cryptocurrencies. One of the most exciting things about Bitcoin technology is its potential to support applications other than currency. We'll study several of these and study the properties of Bitcoin that makes this possible. Hundreds of altcoins, or alternative cryptocurrencies, have been started, either to fix Bitcoin's perceived flaws or to pursue different goals and properties.
We'll look at everything that goes into an altcoin and how they interact with Bitcoin. The use of Bitcoin technology for decentralizing property, markets, and so on has been hailed as a recipe for economic and political disruption. We'll look at the technological underpinnings of these proposals and the potential impact on society. I've gained a strong knowledge of Bitcoin's architecture but wish this course was updated to include the developments of the last two years.
A few lectures on alt-coins would have been useful as well. Great course, a very broad and in-depth overview of concepts surrounding cryptocurrencies and Bitcoin in particular.
Would be great to have an update of course; perhaps once the ICO craze is over? I find this course prepared very well. There are many perspectives and this course does not concentrate on the technology only. I find this course very helpful.
The level is more then just beginner. I enjoyed the lecture series. As many have stated previously, I do think that the assignments assume a sizeable amount of technological knowledge that is not necessarily cohesive with the lectures. Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free.
To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:. More questions? Visit the Learner Help Center. Computer Science. Computer Security and Networks.

Crypto scams are on the rise: 5 ways to avoid them
Company Filings. Companies and individuals are increasingly considering initial coin offerings ICOs as a way to raise capital or participate in investment opportunities. While these digital assets and the technology behind them may present a new and efficient means for carrying out financial transactions, they also bring increased risk of fraud and manipulation because the markets for these assets are less regulated than traditional capital markets. ICOs that are securities most likely need to be registered with the SEC or fall under an exemption to registration. While some ICOs may be attempts at honest investment opportunities, many may be frauds, separating you from your hard-earned money with promises of guaranteed returns and future fortunes. They may also present substantial risks for loss or manipulation, including through hacking, with little recourse for victims after-the-fact. So, what do you need to know about ICOs before investing? Start with some basic research on Investor. Recognize that these products are often sold on markets that span national borders and that significant trading may occur on systems and platforms outside the United States. Your invested funds may quickly travel overseas without your knowledge.

Proof of work is a requirement to define an expensive computer calculation, also called mining, that needs to be performed in order to create a new group of trustless transactions the so-called block on a distributed ledger called blockchain.
