Ethereum: Blockchains, Digital Assets, Smart Contracts, Decentralized Autonomous Organizations

Well written. I finished with a fair idea of what Ethereum is, where it is heading, and some of the problems still to be solved.

Yes there are typos in this book, which can be frustrating - but if you are looking for a book to help your understanding of blockchain technology then this book is a very good read. It is Ethereum focused, but still very useful for overall blockchain understanding.

The book is very badly written, purchase something else.Firstly, the book is 300+ pages long, but each page contains a rather smaller amount of text than what I would expect from a 300+ page book - when you open the book, you immediately feel something's gonna be off.Secondly, the language of the book is wannabe-sexy, but in reality completely fails to bring across the real principles behind blockchain. The reader might leave each chapter with a feeling they understand, but real understanding cannot be attained from this book. The explanations are shallow. The author should write some academic papers in order to realize how to write text that at flows and is easy to follow.Prior to this book, I read Mastering bitcoin and that was a riveting read. In 200+ pages I learned exactly how blockChain works. Here in 300+ pages, I gained exactly zero deep knowledge. Stopped reading the book on p. 140, reading on would be a bad ROI on my time.

A comprehensive look at the state of the art in the blockchain space and Ethereum in particular.The writing style might not be to everyone's taste, but I found it very much worth reading and have recommended it to friends that want a solid introduction to the concepts, pros and cons, and wider issues surrounding blockchain technology and cryptocurrencies.Don't be put off by the 'Preview' status of the book - I get the feeling it will always be a work in progress, updated as developments transpire. (mine is 'Preview 3'.)

This, for now, is the only book on etherium. Unfortunately it is written in Denglisch rather than English. Usages, metaphors and grammatical tropes are all translated word for word from German to English, presumably in the author's head. It doesn't set out to be a technical guide, so unfortunately it comes over as a set of marketing material written by a junior copywriter who failed English in his Abitur, but, because he is convinced he is cool, thinks he can wing it.

Non metto in dubbio la completezza di questo testo, ma non mi piace il modo in cui l'autore discute l'argomento, discostandosi spesso, a mio avviso, dal tema centrale. Anche l'estetica dell'impaginazione non è di mio gradimento.N.B probabilmente ad influire molto sulla lettura è stato l'inglese abbastanza tecnico usato dall'autore.

This book is great!! I have been investing in the crypto market for over a year. I want to make a career as a consultant in the near future. I thought I was pretty savvy as to what it all meant. BUT I was wrong.. Ethereum is so important but This book covers everything and is so well written that even a newbie will be able to make an educated decision if they want to invest or not. Even more important, any investor needs to understand what is happening when prices fall, or what ICO events mean, block chain.etc etc.. This book is so detailed and easy to follow that I just bought another for a friend. There are times when you can tell the author is struggling to explain in simple terms and I need to read until I get where he is coming from but over all this will be my bible as I progress in the learning curve. Plus he provides his email address, welcomes any suggestions as to make the book better. He has redone it a few times since the original printing...Thank you Henning

Das Problem bei Ethereum ist, dass es zwar hochspannend und relevant ist, aber sich gleichzeitig noch heftig in Entwicklung und Veränderung begriffen findet. Das heißt, dass die aktuellsten Informationen oft völlig unstrukturiert sind und alles was perfekt aufbereitet wurde, veraltet ist. Dieses Buch hier stellt (mit Stand Mitte 2017) einen guten Kompromiss dar. Es geht auch deutlich darauf ein, was sich bei Ethereum derzeit noch in der Entwicklung befindet, wenngleich viele topaktuelle Informationen bereits wieder fehlen. Deutsche Werke auf ähnlichem Stand sind praktisch garnicht zu haben. Im Gegensatz zu allgemeinen Büchern über "Blockchains", wird hier sehr konkret auf die besondere Innovation von Ethereum eingegangen.Das Buch liest sich gut, vermeidet es sich in technischen Details zu verlieren, sondern nennt diese als Begriffe und Referenzen und erklärt lieber die Zusammenhänge, Gründe und Konsequenzen. Im Anfangsbereich ist es für meine Begriffe etwas redundant und allgemein gehalten. Ich vermute es richtet sich hier eher an technisch nicht begabte "Entscheider". Nach 1/3 wird es deutlich konkreter und erklärt, gut strukturiert, die wesentlichen Begriffe, typischen Fragen und gibt einem eine gute Orientierung in diesem neuen dynamischen Feld. Es macht die wesentlichen Botschaften und Ideen deutlich und lässt einen erkennen, was dem Konzept von Ethereum so bahnbrechend neu und überaus wichtig ist.

High level overview and historical info. Much information that is up-to-date and good preview of potential future developments.

Si vous souhaitez en savoir plus sur Ethereum (et sur les blockchains en général), non pour programmer mais pour comprendre la nature et les enjeux de cette technologie, ce livre est pour vous (il faut juste parler anglais). Le découpage en sections très courtes couvrant de façon concise et lumineuse une multitude d'aspects différents le rend très facile à lire. Au fil du livre, une compréhension d'ensemble se dégage et s'impose, une gageure pour un sujet aussi complexe.
