secp256k1

secp256k1 is an elliptic curve. It has the formula y^2 = x^3 + 7, meaning that any point (X, Y) on the curve needs to satisfy this.

Notably, the secp256k1 curve is used for Bitcoin.

Curve parameters

• P = 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEFFFFFC2F
• N = 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEBAAEDCE6AF48A03BBFD25E8CD0364141
• A = 0
• B = 7

The generator point is as follows

• Gx = 0x79BE667EF9DCBBAC55A06295CE870B07029BFCDB2DCE28D959F2815B16F81798.
• Gy = 0x483ADA7726A3C4655DA4FBFC0E1108A8FD17B448A68554199C47D08FFB10D4B8.
