How blockchains could change the world

What impact could the technology behind Bitcoin have? According to Tapscott Group CEO Don Tapscott, blockchains, the technology underpinning the cryptocurrency, could revolutionize the world economy. In this interview with McKinsey’s Rik Kirkland, Tapscott explains how blockchains—an open-source distributed database using state-of-the-art cryptography—may facilitate collaboration and tracking of all kinds of transactions and interactions. Tapscott, coauthor of the new book Blockchain Revolution: How the Technology Behind Bitcoin is Changing Money, Business, and the World, also believes the technology could offer genuine privacy protection and “a platform for truth and trust.” An edited and extended transcript of Tapscott’s comments follows.

How the blockchain works

The blockchain is basically a distributed database. Think of a giant, global spreadsheet that runs on millions and millions of computers. It’s distributed. It’s open source, so anyone can change the underlying code, and they can see what’s going on. It’s truly peer to peer; it doesn’t require powerful intermediaries to authenticate or to settle transactions.It uses state-of-the-art cryptography, so if we have a global, distributed database that can record the fact that we’ve done this transaction, what else could it record? Well, it could record any structured information, not just who paid whom but also who married whom or who owns what land or what light bought power from what power source. In the case of the Internet of Things, we’re going to need a blockchain-settlement system underneath. Banks won’t be able to settle trillions of real-time transactions between things.

How disruption can occur

The financial-services industry is up for serious disruption—or transformation, depending on how it approaches this issue. For the research for Blockchain Revolution, we went through and identified eight different things that the industry does: it moves money, it stores money, it lends money, it trades money, it attests to money, it accounts for money, and so on.Every one of those can be challenged.You pick any industry, and this technology holds huge potential to disrupt it, creating a more prosperous world where people get to participate in the value that they create. The music industry, for example, is a disaster, at least from the point of view of the musicians. They used to have most of the value taken by the big labels. Then, along came the technology companies, which took a whole bunch of value, and the songwriters and musicians are left with crumbs at the end. What if the new music industry was a distributed app on the blockchain, where I, as a songwriter, could post my song onto the blockchain with a smart contract specifying how it is to be used?Maybe as a recording artist posting my music on a blockchain music platform, I’ll say, “You listen to the music, it’s free. You want to put it in your movie? It’s going to cost you this much, and here’s how that works. You put it in the movie, the smart contract pays me.” Or how about using it for a ring tone? There’s the smart contract for that.This is not a pipe dream. Imogen Heap, who’s a brilliant singer-songwriter in the United Kingdom, a best-selling recording artist, has now been part of creating Mycelia, and they’re working with an amazing company called Consensus Systems, that’s all around the world, blockchain developers, using the Ethereum platform; Ethereum is one blockchain. She has already posted her first song onto the Internet. I fully expect that many big recording artists will be seriously investigating a whole new paradigm whereby the musicians get compensated for the value that they create.

What could go wrong?

I’m not a futurist. I think the future’s not something to be predicted—it’s something to be achieved. What we’re arguing is that this technology is revolutionary and holds vast potential to change society.What could go wrong? We identified ten showstoppers and we went through them in detail in our research and in the book. There are showstoppers such as the energy that’s consumed to do this, which is massive. Another showstopper is that this technology is going to be the platform for a lot of smart agents that are going to displace a lot of humans from jobs. Maybe this whole new platform is the ultimate job-killer.The biggest problems, though, have to do with governance. Any controversy that you read about today is going to revolve around these governance issues. This new community is in its infancy. Unlike the Internet, which has a sophisticated governance ecosystem, the whole world of blockchain and digital currencies is the Wild West.
