Linux Academy Blockchain Essentials Download

Greetings! Welcome to this Linux Academy’s Blockchain Essentials course. Blockchain has become a buzzword throughout the decade and has enticed many computer, math, and business enthusiasts, as well as the general public. Most people have heard about it because of the cryptocurrency Bitcoin. Blockchain is a revolutionary technology that has offered the world a new way of performing transactions of assets (not just money) of various kinds. It has also given us a new perspective on how to resolve certain issues related to these transactions, and how to implement different principles. If you wish to learn, in depth, the mechanics behind blockchain, to understand the protocols it uses, and to explore its many applications, then this is a course for you. You will be given a thorough introduction to what blockchain really is, and what is important to know in order to grasp it. You will learn what mathematics are behind it and what kind of algorithms and protocols can be used to implement a blockchain of some kind. And there are a lot of them!

If we retrace some of the events that lead to the creation of blockchain, we can go all the way back to 1962 when Paul Baran wrote a paper about distributed communications networks. In 1982 an interesting thought problem was posed called the Byzantine Generals Problem. It looked for a practical way of achieving communication and consensus between entities, despite the existence of attackers or faulty entities. A solution was given in 1999 with the formulation of the Practical Byzantine Fault Tolerance (PBFT) algorithm. Then in 2009 the first ever implementation of the algorithm was given, in the form of the Bitcoin blockchain.
