Two new features are coming to Bitcoin Cash soon, hopefully in the May 2019 upgrade. I'd like to take the time to explain why I'm so excited about them. In short, we will be able to do:
- Payment channels hidden as ordinary payments.
- Atomic swaps hidden as ordinary payments.
- Lightning-style payment channel networks too, if we want.
- Secure chains of unconfirmed transactions involving multiple parties (layer 2).
That all may sound incredible, and I'm going to explain in this document how it is so.
