Just imagine if central banks adopted blockchain technology.
Over the past few weeks, investors have been flocking to bitcoin, the digital currency whose value has soared by about 2,000 percent in the past year alone. And while many economists are cautioning against excitement about bitcoin — which is caught up in what may be one of the biggest speculative bubbles in history — it’s important to note just how revolutionary the technology may be.
Indeed, the technology underlying bitcoin could fundamentally change the way we think of money.
It is only a matter of time before paper money is phased out. Sweden, where about 2 percent of value of transactions are done in cash, may eliminate physical money within five years. Most central banks are working on technologies to power a future digital currency.
