\"BLOCKCHAIN<\/a><\/p>\n

How the Technology Behind Bitcoin and Other Cryptocurrencies Is Changing the World<\/span><\/strong><\/p>\n<\/blockquote>\n

Proposed in 2008 and launched the following year, bitcoin \u2013 a \u201cpeer-to-peer electronic cash system\u201d \u2013 was initially viewed by many as the preserve of geeks and criminals. Yet it has subsequently taken giant strides towards the mainstream. There have been various high-profile attempts to unmask the \u201creal\u201d Satoshi Nakamoto, the pseudonym used by bitcoin’s inventor(s). And in the immediate aftermath of the Brexit vote, some hailed bitcoin surging, as the pound plummeted, as \u201cdigital gold\u201d.<\/p>\n

It is now recognised that the still-mysterious Nakamoto did more than invent a currency. He also solved a longstanding problem in computing, to do with date and networks. His solution was complex, but it involved the use of an infrastructure comprising \u201cblocks\u201d of confirmed transactions that form a chronologically linked \u201cchain\u201d. As other digital currencies, and other blockchains, have emerged, banks and some governments have begun to pay attention, and investment is rocketing. The World Economic Forum (WEF) predicts that, within a decade, 10 percent of global GDP could be stored on blockchains.<\/p>\n

To comprehend the scale of this innovation, it is necessary to understand the extent to which data has until now been held in silos, available to only one authority. The blockchain allows any individual to verify that a transaction existed in a particular form at a certain time.<\/p>\n

Both the potential and the risk are only gradually becoming evident, as is illustrated by the recent case of the Decentralised Autonomous Organisation known simply as the DAO. The idea, in a nutshell, is a company in which funders initially invested in return for voting rights, but which would then operate simply through \u201csmart contracts\u201d running on a blockchain and implemented via software. The DAO was recently launched to considerable excitement, having raised more than $150m in a digital currency known as \u2018ether\u2019, but it was almost immediately hacked, with approximately a third of the ether taken. It is a cautionary tale. Yet in the scale of its ambition, it also helps to explain why some see blockchain technology as almost on the scale of the world wide web.<\/p>\n

Don and Alex Tapscott got in early on this \u201crevolution\u201d. The father-and-son duo is well positioned: Don Tapscott’s 15 books include The Digital Economy (1994) and Wikinomics (2006); Alex Tapscott is the CEO and founder of an advisory firm building blockchain companies. Their book features interviews with leading figures in tech, business and academia, presented in a highly accessible form.<\/p>\n

Blockchain Revolution aims to provide a broad overview of changes the technology could bring about. Since the Tapscotts have a penchant for numbered lists, here are four of their examples.<\/p>\n

First, they suggest, blockchain technology could transform remittances, the largest flow of funds into the developing world; transfers could take place in an hour rather than a week, and with greatly reduced commission. Second, the technology could provide immutable land title registration for the estimated 5 billion people in the world who have only a tenuous right to their land. Third, it could overhaul online identity, allowing not only greater privacy but also the ability to gain value from those aspects of data we are prepared to share. Finally, blockchain technology could help artists and musicians claim ownership of their work and receive a fair share of its value \u2013 no mean feat in the digital era.<\/p>\n

Overall, the shift the Tapscotts envisage \u2013 from hierarchies to networks, and towards a new era of \u201cdistributed capitalism\u201d \u2013 sounds appealing. But each of the four examples mentioned above, like the numerous others in the book, raises the same two questions: Is this blockchain revolution likely? And, is it actually desirable? In answer to the first question, the Tapscotts acknowledge barriers to adoption, particularly in the chapter on \u201cshowstoppers\u201d. As regards the second, they allude to the possibly dystopian consequences as well as the utopian \u2014 at one point, they suggest that blockchain technology could, if we get it wrong, allow institutions to entrench their wealth, provide a platform for a new kind of surveillance society, and even, together with related technological advances, get out of control and turn against humans. The DAO attack, which took place after the Tapscotts finished their book, was not an example of this \u2013 there was a human hacker or hackers behind it \u2013 but is, perhaps, an early warning of the dangers of placing too much faith in code.<\/p>\n

There are other books on the subject but Blockchain Revolution is a highly readable introduction to a bamboozling but increasingly important field. Whether or not the revolution comes about, and if it does, whether or not the effects are entirely pretty, there is huge potential in the distributed ledger invented by Satoshi Nakamoto \u2013 whoever lies behind the name.<\/p>\n

EXCERPTS<\/span><\/h3>\n

\u201cThe financial services industry has already rebranded and privatized blockchain technology, referring to it as distributed ledger technology, in an attempt to reconcile the best of bitcoin\u2014security, speed, and cost\u2014with\u201d<\/p>\n

\u201cCompanies such as Unilever or Prudential are coming to us and saying, ‘We’re very interested in building better data relationships. Can we leverage your platform? We’re very interested in reducing our data liability.’ They’re seeing that data is increasingly a toxic asset inside of corporations.\u201d<\/p>\n

\u201cWho is going to invest in a company that shows you what’s going on quarterly, compared to one that shows you what’s going on all the time?\u201d<\/p>\n

\u201cWe believe that blockchain technology could be an important tool for protecting and preserving humanity and the rights of every human being, a means of communicating the truth, distributing prosperity, and\u2014as the network rejects the fraudulent transactions\u2014of rejecting those early cancerous cells from a society that can grow into the unthinkable.\u201d<\/p>\n

\u201cBitcoin or other digital currency isn’t saved in a file somewhere; it’s represented by transactions recorded in a blockchain\u2014kind of like a global spreadsheet or ledger, which leverages the resources of a large peer-to-peer bitcoin network to verify and approve each bitcoin transaction.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
