[Question] Eliptic curve implementation question

[amirghayes]

Can someone tell me the reason of why we have like million classes and million methods to do Elliptic Curve Mathematics here and on the original bitcoin implementation using the c library, while in the same time I see a Ruby example with less than 200 lines of code that produces same result (public from private) ?

Link to the code I'm referring to

This library isn't a math library, so we hide the math aspect, here how you do with NBitcoin.

var key = new Key();
var pubkey = key.PubKey;
