it only sounds complicated because you're not a developer (I assume, and I apologize if you are) and you're reading technical specs; technically a lightning zap is actually just as complicated.

I'm a programmer in banking for years - and still don't think nip 61 is easy 😀
It's basically the same process as a lightning zap just slightly different
No, I'm not a developer. But I don't mean technically complicated, I mean complicated from user perspective. Actually, I don't see exactly the problem Ecash is solving, or what new stuff is it bringing to table. Besides voucher stuff, I don't get the purpose yet.
