Hi Andrew,
We do not currently have any JubJub implementation in C# or Java.
The class you mention is unknown to us, so is presumably a third-party
addition in some fork.

Apparently JubJub is "a complete twisted Edwards elliptic curve".
I even found (from Bing Chat) a reference to this class:
|org.bouncycastle.math.ec.custom.ed.TwistedEdwardsCurve|
But it was for the Java version of Bouncy Castle, and I couldn't found
its source anyway.
Is there such an implementation in C#? I wouldn't mind porting it from
Java if someone can direct me to the source.
Thanks.
