I have a written a blog post on how Monero uses Cryptography (ECDH, Pedersen Commitments, Schnorr Signatures, Ring Signatures etc) to add privacy & anonymity on the blockchain

https://risencrypto.github.io/Monero/

I have covered most of the cryptography used except for RangeProofs (Bulletproofs) which I plan to cover later in a separate post.

Do let me know if you find any mistakes or if something isn't clear.
