EC-Schnorr
Cryptography
Overview EC-Schnorr, as the name suggests, is a Schnorr-type digital signature scheme over elliptic curve, it's ECDSA's little sister and Schnorr's big brother implemented in the upcoming MuSig in Bitcoin.

ECDSA
Cryptography
Elliptic curve cryptography (ECC) and digital signature algorithm (ECDSA) are more complex than RSA or ElGamal but I will try my best to hide the hairy math and the implementation details.
