I was just proving the math worked. Didn’t get as far as working on privacy implications. Could easily be addressed by a wallet by breaking an amount into the sum of two random components, etc. Anyway, very keen to see this idea is still alive.

No, the issue is that once you have individual keys for every amount everything becomes easily trackable.
Understand. That’s why I stuck with the power of 2 amounts. A bit of a pain to manage for arbitrary amounts, but I got that all working in my wallet implementation, so no longer an issue. I am intrigued on the new approach, though, and keen to learn more!
