Great post. Brilliant news that Amethyst now implements this. On-chain payments was always going to be phase 1. A bit of trial-and-error ahead, but it opens countless doors. Next learn about tweaking keys. Add one to your privkey and then add one point to the pubkey and you have a whole new set of keys.
