I spent the past few days thinking of names. Mako came to mind because I had recently been playing through the original FF7 (maybe the first time in ~10 years). It's short, memorable, looks cool. It checked all the boxes. On top of that, pretty much every name involving the words "btc", "coin", etc. is already taken when it comes to bitcoin projects.
That said, apparently there is a wayland notifier also named "mako", so I may have to think up a different name here. =/
Edit: Hmmm.
"Mako (Japanese: 魔晄, Makō; literally meaning "magic light") is a liquid substance featured throughout Final Fantasy VII. It is the condensed form of lifestream and the primary source of energy used by human beings throughout the world. It is comparable to nuclear energy. Lifestream can condense into Mako via both natural and artificial processes. The terms "Mako" and "Lifestream" are often used interchangeably because one is a derivative of the other."
From here: https://finalfantasywiki.com/wiki/Mako
The thing that catches my eye there is that they say lifestream can condense into mako through natural processes as well as artificial ones.
