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

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

Unlike Bitcoin, which is strictly a currency, Ethereum is a decentralized platform for just about anything. Ethereum is the basis for basic applications (apps), smart contracts, as well as for currency and even decentralized currency creation. Ether is the currency driving Ethereum. Henning Diedrich does a great job at explaining things in a basic form, while also touching on more technical stuff. It is a great read about the history of cryptos, the developers, function, and where things are going into the future. The current financial system, as well as application systems, depend on servers and are outdated and not nearly as secure as what the blockchain technology has to offer. When it comes to the business and corporate realm, these guaranteed systems can execute contracts and run on their own, absent of wasting time with lawyers and courts. There is so much information in this one book about blockchains and the technology behind it. Definitely a great read and perfect for anyone into technology, finance, or coding in general. It reminds me of a mini blockchain bible. The world as we know it is about to change.

This book badly needs an editor. Often, it is just a stream of conscious prose. But, despite all of these flaws, I would rate this highly. There are fantastic and deep insights all over the book. It is difficult to read this book and not learn new things. The author is without doubt very knowledgeable and you can see it in several places in this book. This book will help you in getting (a) a big picture view of blockchains in general and ethereum in particular. (b) a feel for the trade-offs and real issues associated with Ethereum (c) a decent idea of what blockchain is all about.

The only reason this book isn't getting five stars is because it's clearly not been edited. Otherwise it's going to be one of the best books in the market. The author is deeply knowledgeable and enthusiastic on the topic, which keeps the reader engaged. He's fun to read, which is really saying something when it comes to a technical book. But: it's unedited, and the grammatical errors will detract from the perceived seriousness of the message for those who are prone to pedantry (management, engineering management, etc). Just tell them that this is an early release, and to look past that stuff. It's a good book.

I’m sure the book is great, but receiving a used copy was pretty sweet when I paid for a new one.

Interesting read, but I am not sure that it increased my knowledge greatly.

The book covers lot of concepts at a high level. It does not go in to the details. For example book does not take you through how ethash works and in step by step technically how transactions are validated and smart contracts are executed. Lot of internal technical details are missing and I had to surf the web to get things more clarified. But still I think this is the best book out there to learn ethereum in one place. If you can wait till Feb 2018 - then possibly the book Mastering Ethereum: Building Smart Contracts and Dapps by Andreas M. Antonopoulos and Gavin Wood would be a better one.

I can't remember the time when I was irritated and upset that much by TRYING to read this "book". This is a worthless piece of nothing. No practical use, nothing. Just a collection of slogans. Brr.. If you want to keep your mind intact don't buy this pos. Go to ethereum.org - they have a much better wiki.

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.

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.

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.
