I want to learn about Monero in good detail. Unfortunately I am not able to find any good and complete resource which described how this cryptocurrency works.

Most of the papers I found are analyzing the anonymity of Monero. On the homepage of Monero I found this resource. However this is not explaining how Monero works, it is explaining Group signatures which are used by Monero. Still its not explaining how everything works together.

Since Monero is based on the CryptoNote protocol, you should take a look at this resource and the standards here

The most detailed instruction about RingCT I had saw.

https://cryptoservices.github.io/cryptography/2017/07/21/Sigs.html

This describes ring signature, Pedersen commitment and range proof together and clearly.

A self-contained and comprehensive description of the crypto of RCT transactions can be found under https://github.com/kurtmagnus/Monero-RCT-report/blob/master/main.pdf

  • Thank you very much, I found this pdf document very useful as it is comprehensive and complete. For me its really hard to understand how which parts of the original CryptoNote paper and the document you posted are being used and how they are working together. E.g. How relevant is section 4.4. one-time ring signatures in the Cryptonote paper? Thanks :) – Marm Mar 07 '18 at 21:41

I've also noticed a certain lack of comprehensive papers / documentation. I believe that monero's git repo has recently outpaced some of the whitepapers, and now is a good time to start analyzing the code, and building documentation / wikis.

This paper is mentioned many times in the source. Regarding RingCT, there's also this helpful QA.

  • The problem with this paper is that it contains some errors. Also, there are divergences with the code, in that multi-input transactions use a different scheme. Check https://github.com/kurtmagnus/Monero-RCT-report/blob/master/main.pdf It describes signature schemes and links them to the actual implementation – Kurt Mar 03 '18 at 09:04
