Blockchain: Technical Explanation by Andreas M. Antonopoulos
Full technical explanation of Blockchain technology behind bitcoin. How does self-healing network really works? What is “Nakamoto consensus” and how to overcome scaling problems in Bitcoin?
Fear not, brave Steemians, Andreas Antonopoulos knows how to explain complex programming concepts with simple language understandable to a layman persons. And the one who endure through whole lecture, will have much better understanding of Bitcoin protocol, proof of work, forking, and the rest of serious questions that divide serious eCoins from scams.
