 Blockchain. You've probably been hearing that word quite a bit, but there's still a lot of questions like, how does it work? Who uses it? What's the potential? To get some of the answers, we went straight to the source code. First of all, thanks for your time. It's my pleasure. I was just in between Bitcoin trades. I've got to ask, what exactly are you? I'm a digital ledger that connects blocks of data, which can be shared by any number of stakeholders. For example, with me, a bank can better monitor transactions or a transportation company can keep track of shipments. How do you work? When a certain number of people agree on the information in a block, something is added to the ledger. Everybody gets a copy of the same information and nothing can be removed. Who's using you right now? Big brands, publishers, startups. IBM just won two patents for their work, also Apple and Facebook. J.P. Morgan developed its own open-sourced version of me called Quorum. Microsoft, Alphabet, Walmart, the list goes on. Are you safe to use? Define safe. Some people might worry that your technology isn't secure. But that's the whole point of why I was created, to make the transfer of information through peer-to-peer networks solid, safe and secure. Because my data is not held in one point, like in a centralized system, I'm far less vulnerable to being hacked or exploited. How are you making things better? Well, it's hoped I'll create a more democratic and decentralized model for sharing data. My technology has the potential to improve transparency between companies, countries and individuals. For marketers, that means knowing how each digital dollar breaks down across the supply chain. So, you're going to be around for a while? Oh, yeah. You'll see me around for a very long time. Companies are just starting to invest in me with big plans for the future. I may not always look like this, but you get the idea now of what I can do. Thanks for your time. No problem. I'm just around the block.
