After months of work, I've discovered a way to build Chaumian Ecash mints on Lightning that don't hold the users' funds. It's not clear to me yet whether this can actually be made useful or it's only theoretically possible but the sheer possibility makes me incredibly excited.

Oh I should mention that there were around 69 failed attempts before I found a solution that might work. Gotta enjoy the process or lose your mind on the way.

What is the risk of double spend? I am not technical enough to understand all of this, but it seems the further removed from on chain, the greater the risk of double spend. Maybe I'm just dumb and there's no risk of this?

Is it based on the idea that you can provably encrypt the token to a pubkey, and atomically providing the corresponding decrypting privkey as a scalar to a PTLC?

I dont think it is about double spends. It's about someone holding your actual Bitcoin and being able to do whatever they want with it.
