PubkeyAdd
Adds two public keys together using elliptic curve point addition.
Adds two public keys together using elliptic curve point addition (not simple arithmetic).
What it does
- •Treats each public key as a point on the secp256k1 curve.
- •Computes P + Q geometrically, per the curve's group law.
- •Returns the resulting public key in compressed form.
Use cases
- •Combine keys for constructions like key tweaking or additive sharing schemes.
- •Explore elliptic curve point addition hands-on.
- •Verify a manual EC computation against a reference implementation.
