implementation of ECDSA algorithm used in Bitcoin
This implementation is solely for educational purposes. I've used the book Programming Bitcoin: Learn How to Program Bitcoin from Scratch by Jimmy Song as a learning resource.
FE stands for finite element and implements the math for finite fields. Moreover elliptic curves are represented by a simple Point structure.
Bitcoin's elliptic curve (y^2 = x^3 + 7) is implemented as SECP256k1 struct. The library enables signing and verfification operations. See main.go for an example.
go run main.go
