offers secure and verifiable transaction. Considered a breakthrough, the blockchain model can reshape business across the digital economy landscape.

If you haven’t been paying attention to because you don’t understand how a digital currency might be relevant to your business, you might want to reconsider.

It’s unlikely that Bitcoin will replace the dollar, pound, Euro, or yen anytime soon (or ever). However, you’re still going to be hearing a lot more about it. That’s not because people are willing to consider it money. What’s most interesting about Bitcoin actually has very little to do with money — and everything to do with its underlying technology, known as the blockchain, which could challenge our assumptions about what makes commerce secure and trustworthy.

In a blog post last year, Nobel-winning economist Paul Krugman dismissed Bitcoin as a fever dream for anti-government partisans. Still, he agreed that “[I]t does indeed solve an interesting information problem — although it’s not at all clear whether solving that problem has any economic value.”

However, leading names in finance say the blockchain is the economic value. They say that blockchain technology could very well transform the world in the next decade. What’s more, they make the provocative claim that anyone who fails to pay attention today risks being caught as flat-footed as those who failed to see the potential of the Internet.

Behind the blockchain

The details are complex and large amounts of computing power and cryptography are required, but The Economist’s simplified explanation covers the basics. Think of the blockchain as a sequential spreadsheet of transactions, constantly updated on a global network of computers, which serves as a distributed ledger. The ledger is encrypted as it’s being written so the transactions it contains can be safely verified by legions of other computers across the network.

Essentially, the blockchain is the long sought-after solution a logic puzzle known as the “Byzantine Generals Problem”. A general in the Byzantine army sends orders via messenger to other generals about whether to attack an enemy. However, every general knows that one or more of them is a traitor. How can any general be sure that, after receiving an order to attack, the same order was sent to the others and he’s not being ordered to attack on his own? Or that the other generals will faithfully give the correct order to their troops, and not try to undermine the plan? Until now, there’s been no solution that didn’t require introducing a trusted third party who can guarantee to everyone’s satisfaction that an order is authentic.

Similarly, this is why third-party institutions like must exist in today’s economy. Banks provide the high levels of trust required to verify financial transactions. They guarantee that parties legitimately have the money they claim to possess, that they follow through on commitments to transfer ownership, and that these transactions cannot be reversed or otherwise subverted.

Why is the blockchain disruptive?

The blockchain removes the need for a trusted third party to guarantee a transaction. By combining distributed architecture with powerful encryption, the blockchain itself coordinates agreement among all the parties in a transaction — and does so in a way that’s highly resistant to interference.
