BigO complexity with graphs
Math
Overview Big-O notation or Big Omicron (e.g. Ο(n)) also called "asymptotic growth" notation is used to represent the worst-case scenario (the upper bound) for a given algorithm.

Zero-knowledge proofs
Cryptography
Zero-knowledge is a method to prove that you know a secret ``x`` (e.g. a password, private key, piece of knowledge, etc) without revealing that secret.

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.

Schnorr
Cryptography
Schnorr is another digital signature scheme known for its simplicity, no division, no inversion, just plain old multiplication.

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.
