Bitcoin, Ethereum and cryptocurrency dominated headlines in 2017, before an epic crash wiped out billions of dollars in wealth. And after the bubble burst, both bitcoin and the technology powering it — blockchain — fell out of public view a bit. The cryptocurrency crash of 2018 really set the movement back in the eyes of many. But in the background, some of the biggest companies on earth started investing… heavily: Names like Wal-Mart, Anheuser-Busch, Comcast, JP Morgan, Amazon, IBM, Deloitte, EY… you name it, they started experimenting with the technology. All the while, the crypto-prophets kept the decentralized faith. So is blockchain destined to crash like Bitcoin, or will it truly change the world as its proponents claim?

In Think Again episode 3, NBC’s Andrew Stern takes us on a journey from Brooklyn to North Carolina to Texas and back again, all to figure out whether blockchain is really a breakthrough… or bogus. You’ll learn the basics of blockchain, what the real-world applications could be, and why companies are so bullish on the technology. You’ll also hear from perhaps the most infamous blockchain skeptic in the cryptocurrency world.
