Is it perfect? No.
Neither was email when it was invented in 1972. Bitcoin is not the best money on every margin. It is not yet accepted everywhere, it is not used often to quote prices and it is not always a stable store of value. But it is working and the mere fact that it works without trusted intermediaries is amazing.
It’s a computer science breakthrough and it will be as significant for freedom, prosperity and human flourishing as the birth of the Internet. And Bitcoin is just the beginning. If we can replace private payments infrastructure then we can replace other private choke points to human interaction as well.
Now, why should we want to build more public infrastructure? Why should we embrace blockchains over corporate intermediaries? Why should we tolerate their inefficiencies and work to make them better? Why should we want the pioneers of this technology here in the United States and not fleeing overseas?
A simple reason. Because the corporate intermediaries providing today’s critical but privately owned infrastructure are becoming fewer, larger and more powerful. And their failures are increasingly grave.
So roughly half of all Americans, 143 million people, had their social security numbers exposed to hackers because of a breach at Equifax.
The SWIFT network has relayed hundreds of millions of dollars in fraudulent transactions because of hacked member banks in Bangladesh, Vietnam, Ecuador and Russia. The FBI suspects now that the largest of these hacks was perpetrated by North Korea.
Corrupt lower-level employees at an Indian bank, Punjab National, were able to fraudulently certify Swift messages, stealing 1.8 billion dollars. It is the largest electronic bank robbery in history. In fact, it is the largest bank robbery in history.
In October 2016 an estimated 1.2 million internet-connected devices were hacked and turned into a botnet that for several hours made prominent websites unavailable across Europe and North America, including CNN and Fox News, the New York Times and the Wall Street Journal.
Increasingly, physical machines are being connected to the internet to augment their capabilities. They are wired through servers that are owned and maintained by private and trusted intermediates, the so-called Internet of Things (IoT). Pacemakers from St. Jude’s hospital have been hacked. Baby monitors from TRENDnet have been hacked. And Jeeps from Jeep have been hacked to the point where they can be remotely commandeered and driven off the road.
Now, those vulnerabilities are inescapable in systems that have single points of failure. It doesn’t matter if the point of failure is a corporation or if it’s a government. There should not be a single point of failure.
Similar choke points existed before the Internet. If you wanted to deliver a message you have to go through one of three television broadcasters or a handful of newspapers. Private corporations are essential but no critical infrastructure should rely on one or two.
The internet removed single points of failure in communications infrastructure and ushered in a wave of competition among new media corporations building on top of its public rails.
Blockchains can similarly disintermediate critical payments and IoT infrastructure. The technology is not yet ready to answer all of those questions today but it is our best hope.
And as with the internet in the 1990s we need a light touch pro-innovation policy to ensure that these innovations flourish in America for the benefit and security of all Americans.
