About the book

Blockchain Unchained 

Blockchain is indeed a revolutionary capability that put a new spin on how applications could be built going forward. This is why it is impossible to browse the Internet, pick up a newspaper or magazine and not see a headline referencing Blockchain.

One day, Blockchain will be so mainstream that its skeleton will disappear in the same way that electrical wires are part of every wall, but no one notices anymore. But, before then, you should learn what Blockchain is and how it works. Paul Tatro’s groundbreaking new book, Blockchain Unchained: The Illustrated Guide to Understanding Blockchain, will help you do exactly that.

Gene Byrd

Gene Byrd has been prolific in his writing for students. Starting with one of the original authors of Discovering Astronomy he published a self-paced course used for years at the University of Texas and on-line at the University of Alabama. He is co-author of two senior/graduate level texts Cosmology: Foundations and Frontiers and Paths to Dark Energy: Theory and Observations along with a popular book, The Evolving Universe and the Origin of Life.  He has been honored as a University of Alabama College of Arts and Sciences Distinguished Teaching Fellow. His research interests are the dynamics of galaxies, where he discovered “an inconvenient galaxy” NGC4622, which has inner and outer spiral arms winding in opposite directions, and the effects of dark energy in our local universe. Dr. Byrd served as Secretary and Chair of the American Astronomical Society’s Division on Dynamical Astronomy. He has helped organize several international conferences, the last one in St Petersburg, Russia published as Order and Chaos in Stellar and Dynamical Systems. He received a B.S. in physics from Texas A&M University in 1968 and a PhD in astronomy from the University of Texas at Austin. He became a faculty member at the University of Alabama at Tuscaloosa in 1974, retiring in 2009.

Emeritus Professor, Department of Physics and Astronomy at the University of Alabama
