You’ll soon be able to buy and sell health data with tokens, similar to how you’re issued drink tickets at a comedy club. The first step in understanding why tokens will be important to the future of health is differentiating an IPO (initial public offering) from an ICO (initial coin offering), which we’ll discuss here.
The definition of what a token is has changed. Traditionally, tokens were visible representations of value. Arcade tokens were physical coins that you bought with quarters. The words “Arcade Only” were stamped on these coins. The machines in the arcade network didn’t accept quarters — only tokens. Arcade tokens were valid only at a single arcade location. In the future, tokens — thanks to blockchain — will be durable and transferable.
