How do I manually decode outputs?
I'm currently coding a small Monero tool just to better understand how it all works. I already implemented address-generation from scratch (thanks to luigis address test page) and the next step is to scan the whole Blockchain for transactions that…

What cryptography primitives/concepts, other than the basic ones, does Monero use?
The following are the "basic" cryptography primitives/concepts, taught in all beginner textbooks on cryptography:
symmetric encryption (stream and block ciphers. AES, etc.)
asymmetric public-key encryption (RSA, elliptic curves, discrete…

(Non-ring) Wallet signatures
I am reading about ECDSA and EdDSA. I was wondering what the Monero void crypto_ops::generate_signature signature is based upon. From the code, I see that the math to generate one is
k = rand()
t3 = kB
buf = H(data) || pk || t3
c = Hs(buf)
r = k -…

Scratchpad Initialisation : What is the input to Keccak?
So this is probably a question I should be able to find the answer to easily but I am stumped. In the documentation for cryptonight the part on scratchpad initialization says:
First, the input is hashed using Keccak [KECCAK] with parameters b =

Reasons for the way the mask/amount is calculated?
I am reading some monero docs and it says that the mask and amount are generated like this;
mask = x + H(K); //where x is the blinding scalar
amount = b + H(H(K)); //where b is the amount
`K` is the per-output Diffie-Hellman derived shared secret…

Leveraging FHE transpiler in Monero
Google released recently FOSS source code for a "Fully Homomorphic Encryption Transpiler". Here is the associated paper.
How can this be leveraged for Monero ?
For example, can this be used to make the daemon fully ignorant of wallet's data ?
