Summary
Blockchain technology is powering our future。 As the technology behind cryptocurrencies like bitcoin， open software platforms like Ethereum， and disruptive companies like Ripple， it's too important to ignore。
In this revelatory book， Don Tapscott， the bestselling author of Wikinomics， and his son， blockchain expert Alex Tapscott， bring us a brilliantly researched， highly readable， and essential book about the technology driving the future of the economy。
Blockchain is the ingeniously simple， revolution-ary protocol that allows transactions to be simultaneously anonymous and secure by maintaining a tamperproof public ledger of value。 Though it's best known as the technology that drives bitcoin and other digital cur-rencies， it also has the potential to go far beyond currency， to record virtually everything of value to humankind， from birth and death certifi-cates to insurance claims， land titles， and even votes。
Blockchain is also essential to understand if you're an artist who wants to make a living off your art， a consumer who wants to know where that hamburger meat really came from， an immigrant who's tired of paying big fees to send money home to your loved ones， or an entrepreneur looking for a new platform to build a business。 And those examples are barely the tip of the iceberg。
As with major paradigm shifts that preceded it， blockchain technology will create winners and losers。 This book shines a light on where it can lead us in the next decade and beyond。

I am one of the Victims。 At first， The software seemed to be really professional and authentic。 I found many favorable reviews about its performance and delivered results。 So， I decided to invest in it and try to achieve success in the online trading sphere。 Soon， I realized that the software was swallowing all my investments。 IQ option is nothing more than a dangerous and fraudulent platform。 I invested over $40，000 and couldn't withdraw my money， months passed and still nothing。 So， I reached I am one of the Victims。 At first， The software seemed to be really professional and authentic。 I found many favorable reviews about its performance and delivered results。 So， I decided to invest in it and try to achieve success in the online trading sphere。 Soon， I realized that the software was swallowing all my investments。 IQ option is nothing more than a dangerous and fraudulent platform。 I invested over $40，000 and couldn't withdraw my money， months passed and still nothing。 So， I reached out to a certified recovery agency to help me recover my funds， Good News！ I have been able to recover 80% of my loss in just a few days。 I really can't tell how happy I am。 Want the same help？ Contact : JimFundsRecovery at Consultant dot Com。 。。。more

Really expanded my understanding of blockchain technology which is precisely what I was looking for in a book。 A lot of the book， however， goes into really interesting ideas about what can be done in the future and it isn't clear to me why Bitcoin is necessary for that。 Really expanded my understanding of blockchain technology which is precisely what I was looking for in a book。 A lot of the book， however， goes into really interesting ideas about what can be done in the future and it isn't clear to me why Bitcoin is necessary for that。 。。。more

It was a pretty deep dive into the world of blockchain， something I wanted to read for a while now。 However， like with every nascent technology in recent years， it seems that once you have a blockchain hammer， everything looks like a nail to you。 A lot of problems that blockchain companies are trying to solve that are mentioned in this book， could probably use some more general， tried and tested technology。

The book will be useful for those who need a cursory knowledge about the Blockchain Technology。 Earlier chapters can excite the readers with the potentials of such a ground breaking technology。 But later ，contents start becoming repetitive and lacking details。 Also， the book adopted fullscale praise for the new technology rather than critical analysis。

A bit of a disappointment。 It was like a book of collected articles and thinkpieces， sorely lacking cohesion。 It described all the things blockchain implementations could disrupt， but very thin on the details of how， or who would be doing the disrupting。 Technological detail gave way to corporate america waxing lyrical。

The book doesn't cover much how blockchain works， and technical details。 It is about how blockchain is changing and further going to change different aspects of our lives and how the world works。 There are some examples of some current experiments。 Chapters in the book are short and fast to read， but I didn't find most of them engaging and for some I didn't find clear point what are they about， it felt like random talking。 The book doesn't cover much how blockchain works， and technical details。 It is about how blockchain is changing and further going to change different aspects of our lives and how the world works。 There are some examples of some current experiments。 Chapters in the book are short and fast to read， but I didn't find most of them engaging and for some I didn't find clear point what are they about， it felt like random talking。 。。。more

Page after page of word salad doused in expired dressing。 Just glowing praises of block chain technology written by an author that doesn’t understand the subject。 What you wanna bet he wanted payment in American dollars any not Dogecoin

Consider this an effigy to blockchain。 There’s nothing about “how” it’s actually going to change anything。 Instead， the authors jump right to the conclusion and spend the entire book regurgitating what blockchain supporters in academics have told them。 Even a simple chapter explaining what blockchain is and how it works and how that relates to their speculation would have given me the confidence that they had thought through their claims。

Too much time （read: pages） was dedicated to Bitcoin。 However， speaking of Finance 3。0 world and technologies staying behind it - you should pay more attention to such Networks like Ethereum， etc。 Bitcoin is just a GOLD。 It just ensures your value is safe。 However， Ethereum is the lifestyle！ Is what you use in your daily life！

This book gives an overall picture of how blockchain technology might change the way we do business and transact。 It gave a clear picture about both the pros and cons and the idea behind the technology。 However， some aspects of the book were too technical for a layman like me to grasp and wished for a easier explanation to these concepts。

It might have been because of my lack of background on the topic， but I found the content remarkably wordy and the terminology often when right over my head。 The book focused on some interesting applications of cryptographic technology。 While I learned some interesting background on blockchain， I would only recommend this book to readers with more background in this area。

This is by far the best book I've read so far on how the blockchain works。 I'm brand new to investing and even newer to crypto， and this book lays it all out perfectly。 Prior to this book， I read four or five books that gave a brief overview of crypto， and one was way too in-depth about the history of currency。 I bought this book because from my research， I knew that the blockchain must be more than just an investment opportunity， and it absolutely is。 The book starts by explaining the blockchai This is by far the best book I've read so far on how the blockchain works。 I'm brand new to investing and even newer to crypto， and this book lays it all out perfectly。 Prior to this book， I read four or five books that gave a brief overview of crypto， and one was way too in-depth about the history of currency。 I bought this book because from my research， I knew that the blockchain must be more than just an investment opportunity， and it absolutely is。 The book starts by explaining the blockchain， why it's decentralized， and how it came to be after the crash of 2008。 Like many people， I lost faith in Big Banks in 2008， and crypto is the solution。 The authors did an incredible job explaining all of the ways the blockchain can be used to help with wealth equality and a better system for everyone。 They also discuss the potential of the blockchain in all aspects of the world and how it can help make the world a better place。 While the book is very pro-blockchain， I could see how some people would argue that the technology can be used for bad intentions by billionaires and big companies， but we'll deal with that as we continue this journey。 My primary takeaway from this book is that we've barely scratched the surface with cryptocurrencies and the blockchain。 So， if you're like me and thought you were too late， you're definitely not。 This book helped me realize that I can invest in companies who have values that I believe in while also making a little bit in return to support myself and my family。 。。。more

I got to know about this book from a course available on Coursera。The authors of this book have built the course in collaboration with INSEAD。 The book is very informative and thought provoking。 But throughout this lengthy text， the authors tend to advocate the use of this technology rather than being more objective about it。 The last few chapters and the Afterword （in the 2nd edition） are perhaps more balanced。 Many Blockchain startups referred in the book and also in the course have failed。 （A I got to know about this book from a course available on Coursera。The authors of this book have built the course in collaboration with INSEAD。 The book is very informative and thought provoking。 But throughout this lengthy text， the authors tend to advocate the use of this technology rather than being more objective about it。 The last few chapters and the Afterword （in the 2nd edition） are perhaps more balanced。 Many Blockchain startups referred in the book and also in the course have failed。 （Although that is a typical phenomenon among startups across any industry。） Hence， one should not get carried away by a quite rosy picture of the possibilities of Blockchain revolution that is painted in the book。 That revolution might still happen though， at least in certain sectors such as Finance， Supply Chain， and so on。 The book however is certainly worth reading， since it contains nice expositions on nature of economy and society with good anecdotes。PS: This book does not describe the blockchain technology from an engineer's standpoint。 For technical details refer other online sources。 "Mastering Bitcoin" by Andreas M。 Antonopoulos is highly recommended for a deep technical understanding of the first and foremost of all blockchains。 。。。more

blockchain！Is the author biased？ YES， the author is the epitome of bias。 He is so biased that he refuses to entertain the though that Blockchain might not be the silver bullet。Is this book absolutely useless？ NOUnfortunately， despite the author's lack of editorial abilities， despite the bad editing， lack of common sense about how long a book about blockchain can be （before the readers lose interest） and the completely biased view， The book still packs a punch。 How？ You might ask？ To get an answer to this question， you must first understand what this book is！It is better to get at it if we understand what this book is NOT。1。 This is not a book that is written to explain how Block Chain works - NO。 This is not a technical book。2。 This book is not written to explain the pros and cons of Block Chain3。 This book is also not written to provide you a 360 degree view of Blockchains， the author cannot fathom blockchains failing anywhere。 WHAT IS THIS BOOK ABOUT？ THIS BOOK IS A COLLECTION OF ALL THE BUSINESS MODELS， NGO MODELS， CIVIL SERVICES MODELS OR ANY OTHER TYPES OF MODELS/USECASES WHERE BLOCK CHAIN "CAN" BE USED。One must understand that the author simply talked about all possible use cases where BLOCK CHAIN can be used。 From Medicine， Relief Funds， WHO， Education， sports， music， hollywood， HR recruitment， corporations， stock markets， futures trades， FOREX trades， remittances， smart contracts， this books has all the possible use cases where blockchain can be used。 The list is pretty huge， and extremely comprehensive。 The author has not left anything out。 He left no stone unturned， he also coupled these use cases with real life companies trying to solve these problems sprinkled all along the book。 But， the author does not and cannot guarantee that these startups will be around in a few years。 Most of them might simply disappear due to lack of a profitable self-sustaining business model。WHO SHOULD READ THIS BOOK？This book must not be read by anyone for casual reasons， unless they are managers fishing to find a use case that they can pursue as new initiative in their corporations。 This book is for entrepreneurs who are on a look-out for avenues where they can exploit the blockchain technology。Even for such a niche audience this book does a very bad job， thus it deserves less than 3 rating for the excruciating pain it puts readers through。 Because is more of a reference book than a book you can learn from。 For all that we know a simple search in the PDF version of the book will reveal the exact pages where your topic of interest lies， in my case I read this book to understand where blockchain can be applied with respect to Human Resources i。e。 Recruitment and I did find an answer。 I would strongly advice people who don't have this motive at the back of mind from reading this book。 More over this a REFERENCE BOOK， a book you are not meant to read from end to end， but a book you must read selectively， pick and choose the exact section you must read。But I refrained from giving a single star for this book， because there is great value in this book， at very specific locations。The book is not a simple collection of all the block chain applications。 The book has builds upon the work of nobel laurates to establish firmly why blockchains would work in the first place。Thanks to this book I learned answers to very important questions。1。 Why do firms exist in the marketplace， why can't people simply work alone in their own office and collaborate？The answer to this question is provided by a Nobel prize winner Ronald Coase， for his paper， NATURE OF FIRM2。 Why can't an entire country be one single firm？ What happens when such an effort is attempted？Or simply put， why did USSR and India go bankrupt chasing Socialism？We all know the answer to this question， columbia， venezuela， ussr， india， all went bankrupt， due to central planning commission and five year plans， i。e。 when the entire country tried to become one company。The answer to this question is also provided by another nobel laurate， Oliver E Williamson， for his work on Transaction Cost Theory。Thus the book is logically correct， i。e。 it is well researched and has the work of noble laurates at its code。 It is not just wishful thinking of the author。THE FIRST FEW CHAPTERS ARE MASTERPIECES。The author starts from the GOD PARTICLE and GOD as MIDDLEMAN and then explores all possible combinations。Somewhere along the way the author include a small paragraph about "BIT TORRENT" and DApps， in fact they can be used to get almost everything that a Blockchain does with some clever tweaking。 Not sure why the author deliberately sidelines the previous p2p revolution which bought us many great technologies like dc++， shareaza， netaza， and infact skype works on p2p tech。The author deliberately downplays this great tech to promote his Blockchain ambitions。I really wanted to slap some sense into the author at this point， because he seriously refuses to acknowledge any other tech， other than blockchain that could solve the world's problems。Whether blockchain stands the test of time or not can't be predicted by anybody accurately。 But bitcoin is here to stay much like the internet， once you see something it is impossible to unsee！ Similarly this tech will be used all over the place from tracking pets to marry your spouse over a smart contract on blockchain， but what sticks and what does not will only be decided by the free market。Until that point， this book is simply SCIENCE FICTION， and not science， or Business Fiction and not Business。 Another very interesting aspect that the author talks about in the book is THE LEARNING CURVE OF DICTATORSThe story about Sergeyevich Termen and his inventions of etherphone/thermin and how his inventions were usurped by Lenin and Stalin。Termen stumbled upon a means of making music out of thin air。 Whenever he put his hands near the metal terminals， the pitch of the signal changed。 He learned that he could manipulate the pitch by the precise position and motion of his hands。 He called his device the “etherphone，” known today as the theremin， an anglicized version of his name。 The other app was a larger-scale version of this apparatus， one that was sensitive to movement within a radius of several meters。 It was the first motion detector—sentry of the ether。 He demonstrated both of theseinstruments at the Kremlin， playing his etherphone with abandon for Comrade Lenin。 While Lenin delighted in the etherphone， he put the motion detector immediately to work in watching over the Soviet stashes of gold。 If anyone crossed the electromagnetic line around the gold， they’d set off a silent alarm。 Big Brother suddenly had electric eyes。The moral of the story is simple: Termen’s devices brought both lightand darkness to the world。 In a poignant talk， “Our Comrade the Electron，” Maciej Ceglowski pointed out these two themes in all of Termen’s inventions: as soon as they gave shape to airy nothing， they were usurped by dark forces。 Lenin even co-opted electricity in his propaganda， equating communism with Soviet power plus the electrification of the country。But， it was Stalin who rounded up Termen and his peers， threw them into the Kolyma gulag， and forced them to invent instruments of tyranny。This cautionary tale highlights what happens when rational tools created by scientists and great inventors fall into the hands of despots and irrational institutions like religious cults。Thanks to the author I also discovered about the Wassenaar Arrangementencryption technologies are either not legal for individual use or not readily available in those countries whose citizens need them most。 The Wassenaar Arrangement， a multilateral export control regime that technologically advanced nations agreed to， governs the export of “dual use” products， that is， those that could be deployed for both good and evil。 Wassenaar’s original goal was to keep high-tech products out of the hands of dictators in North Korea， Libya， Iran， and Iraq。 Anonymity and encryption technologies such as public key infrastructure were considered dual use。Today， in countries such as Russia and China， both individuals andcorporations—including foreign firms—must seek authorization to usethem。 In countries where their use is discretionary， governments—even theObama administration—have asked tech firms to include “backdooraccess，” that is， a secret means of bypassing the normal authenticationprocess （e。g。， logging on with a password or other security code） andgaining remote access to a computer and its data without authorization ordetection。 It is far more insidious than Big Brother， because at least everybody knew that Big Borther was watching。The book becomes a bit interesting towards the end！ The book is mostly repetitive， as the author goes on from one application to the other and how blockchain will revolutionize the use case like magic。The author does not care to talk about unique challenges that each of these diverse fields might pose to blockchain and how it must be morphed。 Instead he packs all the objections towards the end of the book。 While the author was running from one application to the next， it reminded me of the Sherlock Holmes story templates。 Every story has the exact same pattern of detection that Sherlock Holmes uses and the exact same cookie cutter template to create huge drama and reveal it before an audience。This book is a collection of business models - It reminds me of this book - The Business Model
