What’s a blockchain? And why do I need to put money in there?

Trying to figure out what the blockchain is or how it works is like the olden days of the internet when college students were asking: what’s a modem? What’s this Mosaic thing? And why do I need it to do my homework?

Trying to explain the future possibilities of the internet in the early 90s is like explaining the future possibilities of blockchain today. A recent IBM commercial about how food safety is improved when food can be tracked on the blockchain does little to educate anyone on what that technology is, or does, or why something similar doesn’t exist already. But it does show blue-chip companies developing blockchain for future business.
