DAVE BIRCH: The future of money the great sweep of historical change, would tend to indicate that we havent seen the revolution yet.
WHAT HAPPENS NEXT: FUTURE OF MONEY
TEXT ON SCREEN: A COLLABORATION BY QUARTZ AND RETRO REPORT
NARRATION: People on the tiny Pacific island of Yap have preserved an ancient culture amid centuries of change. On a recent afternoon, Cyprian Mugunbey took his son to see a time-worn piece of the family fortune.
CY MUGUNBEY: This piece of stone money was given by someone to your grandfather, my dad. He built a house for some people.
NARRATION: There are thousands of these stones all over the place here. Theyre actually an ancient form of currency. And crazy as it sounds, understanding how they work offers a window into the future of money.
THEODORE RUTUN (SPEAKER, YAP STATE LEGISLATURE): My name is Theodore Rutun. Currently, I am the Speaker of the Yap State Legislature. My family has some stone money.
NARRATION: Yap has no precious metals and little in the way of stone. So centuries ago, voyagers began traveling to a neighboring island, about 300 miles away, in search of something rare. What they brought back became a form of wealth that has fascinated scholars because it works without bills or banks or just about anything else you think of when you think of money.
ROSALIND ANDERSON (ANTHROPOLOGIST, UNIVERSITY OF HUDDERSFIELD): They would cut it out of the stone, hack it out, smooth it. They would roll it down to their canoe, and put it on the canoe or on a raft.
THEODORE RUTUN: Normally, it would take a year or half a year. The value of stone money, if you want to put it in a nutshell, comes from the work that goes into that particular piece of stone money.
DAVE BIRCH (CO-FOUNDER, CONSULT HYPERION): And then you sail it back to the island and then it goes outside the chiefs house. But the twist on the story, which makes it interesting to people like me is that sometimes when they would bring in the rocks back from the other island, thered be a storm and theyd have to throw the rocks over the side of the raft.
NARRATION: With money this heavy and hard to lift, it often changed owners without actually changing hands. A stone outside your house can become your neighbors simply by both of you saying so in public. And the oral tradition was so strong that, by an early account, even money tossed overboard could remain part of the system of exchange.
DAVE BIRCH: I mean, what difference does it make whether the stones outside my house or at the bottom of the Pacific?Its not going anywhere. And so you have this idea that who the money belongs to is what everybody remembers the money belongs to.
NATHANIEL POPPER (AUTHOR, DIGITAL GOLD): Money is a communal story about who owns what. Its always been just a matter of who we trusted to tell that story.
NARRATION: Yaps ancient system and the digital dollars in your bank work because what you have is connected to who you are. But theres a big difference, one that could make Yaps money a model for the future. Yap islanders remembered who owned these stones without needing any intermediary like a bank or government or company to keep track of things.
ROSALIND ANDERSON:When you live in a small village people all know the story. Where did the stone come from?How many times its been exchanged.
THEODORE RUTUN:The more people who know, the more secure it is.
NARRATION: And in essence, this is the idea underpinning some of the newest forms of digital money were seeing emerge now, like Bitcoin.
NATHANIEL POPPER: In some sense, Bitcoin is a return to this earlier concept of communal recordkeeping, of communal memory.
NARRATION: Bitcoin appeared shortly after a monster crisis shook the worlds faith in our current banking system. In 2009, an anonymous programmer or a group of them launched what appeared to be an alternative system, founded on principles an anarchist would love. Without any government or banking intermediaries, the system issues its own money and verifies transactions using a powerful network of computers.
VINAY GUPTA (FOUNDER, HEXAYURT CAPITAL): They basically took a core function of government and they automated it. Instead of the bank and the banking system, instead of the dollars which are issued by the government, you have a piece of software that gives you a thing that looks like a bank account.
NARRATION: Just like with physical cash, you dont need a photo ID or physical address to use Bitcoin. And just like cash, once you spend a Bitcoin, youre moneys as gone as if youd slipped a dollar bill into a vending machine.
DAVE BIRCH: So having things in the virtual world that you cant copy that actually makes the virtual world more like the mundane world, right?
NARRATION: And people who believe in the technology have been buying a lot of Bitcoin. Eight years after it launched, the network was worth more than $25 billion. The security of that wealth is guaranteed in part by putting the entire list of who has what onto a network of computers instead of in one central place. And these computers simultaneously track and update every Bitcoin transaction around the world.
LAURA SHIN (SENIOR EDITOR, FORBES): They group together transactions that happen around the same time into what they call blocks. And then those blocks are linked, which is why you often hear that the technology behind Bitcoin is called blockchain.
NARRATION: You can think of a blockchain as a global, digital, automated version of the oral tradition that tracked ownership of the stones on Yap. In essence, a blockchain is just a high tech, universal record book.
AMANDA GUTTERMAN (CHIEF MARKETING OFFICER, CONSENSYS):Imagine that you have a piece of paper and that any infinite amount of people are also holding a piece of paper.What blockchain technology does is it makes what you wrote on your piece of paper show up nearly at the same time on everyone elses piece of paper exactly how you wrote it.
LAURA SHIN: Theres literally a ledger of every single Bitcoin transaction in history.
NARRATION: And because the network creates and cross checks this ledger, no central authority is necessary. But this also means its hard to find anyone to appeal if a transaction goes wrong.
DAVE BIRCH: If I want to operate in a community where the money is completely anonymous and I might get cheated and its my problem to take care, fine.Right? But sooner or later, your grandma is going to press the wrong button on an e-mail and all of her money is going to be transferred to somewhere in Eastern Europe.
NARRATION: So what does this mean for the future of money? Bitcoins more anarchist features like the near anonymity, the lack of central control suggest its probably a long shot to replace your checking account.
But people who study the technology that powers Bitcoin say blockchains will likely change how the world does business.
JOSEPH LUBIN (FOUNDER, CONSENSYS):2027, itll be everywhere. Theyre going to permeate everything we do.
NARRATION: Many of the programmers working here with Joe Lubin are betting on a future where blockchains will make it so that complicated, paper intensive stuff like opening an account or renting property or getting a loan stuff that normally takes days or weeks could be done instantly.
JOSEPH LUBIN: If youre trading a piece of land for money, perhaps, theres no reason why it cant clear and settle in the moment of the transaction.
NARRATION: In places where the financial system already works fine, this means banking could get a little simpler, cheaper, harder to hack. But for nearly 2 billion people in the world who right now cant get bank accounts at all, the stakes are a lot higher. Just look at what simpler cell-phone based banking has done in places like East Africa.
DAVE BIRCH: If you previously had to spend four hours on a bus journey and standing in line to go and pay your water bill and now you can pay it in a couple of seconds on your phone, your lifes completely changed.
NARRATION: Technologists say blockchains are likely to transform far more than money. If youve got something valuable a birth certificate or passport, stock or property deed you may soon be using a blockchain to find it, check it, or sell it to someone else.
LAURA SHIN:You can think of a blockchain, or a distributed ledger as a golden record of the truth. These technologies are about to disrupt every industry that has been based on trust.
NARRATION: Predictions like this have touched off something like a digital gold rush. Investors in 2016 poured more than $1 billion into new cryptocurrency and blockchain projects on the belief that the technology could simplify trust-based transactions that so many of us need to do. But that future comes with some risks. Digital assets that arent backed by gold or governments only have value if people keep believing they do and only if the computers creating them remain secure. And one of the most far-reaching risks goes back to a dilemma that comes built into Bitcoin.
NATHANIEL POPPER: It is in some ways the most private financial system and in some ways the least private financial system.You can just be a series of letters and numbers, and nobody will know that was you sending the money.But once somebody does tie you to that serial number, they know everything that youve done.
NARRATION: Putting still more aspects of our lives onto blockchains like property records and debts, identity documents and medical or criminal histories this could vastly cut down on the red tape in our lives. But it could also vastly simplify efforts to track our every move.
AMANDA GUTTERMAN: With access to great amounts of data comes the responsibility to use it ethically.
VINAY GUPTA:So, if we wind up in a society where there is a single computer record for every single thing in the society and those records are kept in perfect order, that might work quite well in a modern liberal society like Switzerland. The problem is if something goes wrong.welcome to your authoritarian superstate. The virtues that we want to preserve are virtues that were going to have to consciously fight for because the technologies themselves dont bring those values with them.If you want those technologies to have those values, you have to bring them yourself.
NARRATION: This suggests that the future of money may well be multiple. Different systems that embody different values about privacy, convenience or community that different groups want to preserve.
The rituals ofYapsheritage persist because they represent values the community here wants to maintain. Islanders may use dollars at the grocery store, but stone money still has its place in ceremonies and exchanges that reinforce social ties. And thats why it will likely endure, no matter how central blockchains become to the financial system.
DAVE BIRCH: If we are moving into this era where the money itself is much cleverer and the money is much more closely linked to communities, that makes money work in very different ways.But the way of thinking about that is much more where we came from.
