Demystifying Blockchain Not Bitcoin

This is a pretty clickbait-y title. Bitcoin is the original use case for the blockchain, the most important use case, and possibly the only use case.

Most of what we hear hyped as blockchain products aren't public; they're just inefficient versions of private databases which defeat the whole purpose of having a blockchain.

Blockchains existed before bitcoin. Bitcoin came about because a safe digital currency is something humanity actually needs. Is there another blockchain product that we really need?

The most popular distributed app is Cryptokitties. I rest my case.
