''One clarification that often gets left out of this debate is that a better version of PayPal can be built on top of Bitcoin (ie.via Lightning) in a situation where the base layer is used for the digital gold use case.

There are reasons why nothing typically hits a secure database layer directly, including providing greater scalability.
