And (perhaps more importantly) Ed25519 does not require a new random number on each subsequent signature, thus is deemed to less vulnerable to a faulty random number generator (or injection of virus thereof in the operating system).

Is this advantage of Ed25519 over Secp256k1 negated assuming perfect compliance in avoiding BTC address reuse (since if a faulty RNG was used the balance of the at risk address would already be 0 after every transaction)?

That perfect compliance is impossible isn't it, because how do you delete your public key from forums and other places it has been copied out-of-your-control. Don't tell me that the Bitcoin Wiki and the core devs never acknowledged this Roll Eyes

There is a way though to get perfect compliance which I am using in my design because I use one-time Lamport/Winternitz signatures (although I could use Merkel trees for multiple signatures at the cost of a just marginally longer signature) for the 20 times faster verification speed (at the cost of an exponential blowup in bandwidth at higher bit security), but this way is not encoded in Bitcoin so can't be used there.

See the following I wrote comparing Ed25519 and hash-based signatures (some info on the performance of Ed25519 also):

P.S. if you see any improvement in my work, it will be because of improving health. I have some signs that my high dose herbal treatments (curcumim, moringa, bitter melon, mangosteen) might be working. I believe possibly (unfortunately self-diagnosis no blood work nor doctor visit since the 2012 doctor screwed me up) my health issue is a messed up pancreas or gall bladder possibly partially blocking my bile duct which would explain why I got so ill every time after I eat.

You all have no idea what it is like to have this sort of illness. Even bending down to scratch your foot becomes chore. Lifting your fingers to type on the keyboard takes a few deep breaths to gain the energy. Thinking about code becomes a chore and not a pleasant challenge. You really don't understand until you walk in another person's shoes. Any person who knows what they were capable of throughout their life and are unable to do because of some painful and chronic disability, is going to exhibit psychological stress and will attempt to cope either by going into depression or fighting back, both being a form of abnormality and dysfunction. I hope that is enough said.

Forcing perfect compliance through cryptography sounds great. Unfortunately I cannot pretend to understand the math and cryptography behind everything you say except on a conceptual basis.

It doesn't gain anything from an anonymity perspective (and is arguably retrogressive), if that is what you were thinking. We pay to a name instead of an address. The address can change and the name remains the same. For security it helps, and my greater motivation is eliminating lost payments (payments to addresses for which no one knows the private key) and overhead for microtransactions (and potentially IoT).

Edit: it is a usability feature for targeting the masses, and I think ShadowCoin has a similar feature but maybe not for the same motivations.
