@bascule @matthew_d_green @JacksDismay Not so. That curve is birationally equivalent to Curve25519. It's the same curve in disguise.
@tqbf @pbarreto @hyperelliptic @matthew_d_green @JacksDismay frustrating for us all, indeed

@bascule "obsoletes Curve25519" but Montg doesn't work for sign, thus need to fix terminology@tqbf@pbarreto@matthew_d_green@JacksDismay -
@hyperelliptic@tqbf@pbarreto@matthew_d_green@JacksDismay the Montgomery form loses 1-bit of info and doesn't support addition right? -
@bascule@hyperelliptic@tqbf@pbarreto@matthew_d_green@JacksDismay x-only coordinates do; Montgomery curves themselves don't. -
@sevenps@hyperelliptic@tqbf@pbarreto@matthew_d_green@JacksDismay specifically talking about the Montgomery form of Curve(/Ed)25519 here
