To really understand what is special about Bitcoin, we need to understand how it works at a technical level. We’ll address the important questions about Bitcoin, such as: 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? After this course, you’ll know everything you need to be able to separate fact from fiction when reading claims about Bitcoin and other cryptocurrencies. You’ll have the conceptual foundations you need to engineer secure software that interacts with the Bitcoin network. And you’ll be able to integrate ideas from Bitcoin in your own projects. Course Lecturers: Arvind Narayanan, Princeton University All the features of this course are available for free. It does not offer a certificate upon completion.

Syllabus

  • Introduction to Crypto and Cryptocurrencies
    • Learn about cryptographic building blocks ("primitives") and reason about their security. Work through how these primitives can be used to construct simple cryptocurrencies.
  • How Bitcoin Achieves Decentralization
    • Learn Bitcoin's consensus mechanism and reason about its security. Appreciate how security comes from a combination of technical methods and clever incentive engineering.
  • Mechanics of Bitcoin
    • Learn how the individual components of the Bitcoin protocol make the whole system tick: transactions, script, blocks, and the peer-to-peer network.
  • How to Store and Use Bitcoins
    • 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.
  • Bitcoin Mining
    • 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?
  • Bitcoin and Anonymity
    • 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.
  • Community, Politics, and Regulation
    • 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.
  • Alternative Mining Puzzles
    • 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.
  • Bitcoin as a Platform
    • 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.
  • Altcoins and the Cryptocurrency Ecosystem
    • 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 Future of 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 sent $130,000 to trade crypto assets on the website coinbitjzsc.top but when I tried to withdraw funds, I was told my account had been frozen because of “suspicious activity”. I provided proof of identification and proof that my funds had been transferred from their crypto asset account. The site then told me the account was marked with a “danger signal”, and that I needed to pay a “risk deposit” of nearly $40,000. I was not able to withdraw any of the money from their account until I read about Recoverycoingroup At Gmail Dot Com, after I contacted them and did all I was asked to do, in less than 72hours I received my money back into my wallet. I strongly recommend Recovery Coin Group for anyone in similar situations.

    I began using what I believed was a crypto asset exchange called BEX-EX, utilizing the web domains bex-ex.xx and BEX.ts. I transferred $67,500 in funds to the account on the exchange but was unable to withdraw any funds after making over $208,094 in total. I was frustrated and had to search blogs, I read so much about "hackwest at writeme dot com" and decided to contact them immediately, long story short, my money was recovered and I am excited to let the world know about them.

    I tried everything I could to get my money back after I lost it to an online scammer last month using Bitcoin transactions. Eventually, I came across a crypto recovery expert agency that was assisting many other people in getting their money back. I contacted them and sent them a complaint via their company email, RECOVERYEXPERT AT RESCUETEAM dot COM, and provided them with all the information they required for the recovery.
    I verified the payment in my wallet account in less than 48 hours. To effortlessly retrieve all of your lost money without having to pay anything up front, please get in touch with them right once if you have fallen victim to an online scam.

    You can not tell anyone how to spend their earnings or money, but I'll use this opportunity to create a witness on how I was being swindled of my hard earned savings to a so called Profitable Bitcoin Investment, This bogus company took over $80,000 from me, thanks to the review recommending about the BACKEND RECOVER TEAM I was directed to reach out to them. It was within the 73rd hour of interacting with them that I got 90% of my bitcoin and other crypto assets back into my portfolio wallets, I was amazed and had to praise them whenever I can, for the job well done. BACKEND RECOVER AT RESCUE TEAM DOT COM is their mail to reach out to them.

    In recent times, technology has proven to be more sophisticated and just like any other currency that can be stolen or lost, crypto and other digital assets has proven to be more difficult to recover but not impossible, and just like searching for any other monetary currency, you need a trustworthy and honest agency or personnel who can track and recover the value lost or stolen, in my case I hired [email protected] they followed the blockchain and was able to recover over 247k of my stolen funds within a couple of weeks. The fees for the services I received was fair and communication was excellent
  • Very interesting course explaining cryptocurrencies in different aspects. Highly recommended to anyone interested in bitcoins, cryptocurrencies or just normal currencies as well.
    As mentioned in other comments, please, note you will not have any types of homework and will not get any statement of accomplishment.

    Finally, there is a reliable and effective service we all can rely on! I can only imagine how many people are having problems with crypto-related issues and are likely also unsure of their ability to find practical solutions. Easyreclaim is rightfully the best provider of recovery service and their ability to recover funds very fast. They helped me to recover 850,000USD that I lost due to online cryptocurrency theft Get in touch with them on: easyreclaimer@gmailcom They are simply the best recovery company.
