I have made an experimental fork which was forked from the Monero v0.13 release. The forks main focus is to test post-quantum signature keys for Monero. Although it's working, it still has a lot of ...

Good day, I am trying to integrate a post quantum signature scheme into the Monero codebase, first I had so many issues with key sizes and key derivations, but right now it seems to be partially ...

I have a pretty ambitious experiment in mind, and more of it is like testing how would a crypto currency behave if it would have some post quantum keys, like 2KB of key sizes and signatures. So I ...

I know most cryptography Monero uses relies mostly on EC crypto which would be easily broken by a quantum computer powerful enough. What options does Monero have in the future to protect itself?

So I was wondering, if say a quantum computer is ever made could it be used to break the privacy of past transactions? Would that mean at that someone could just work though the blockchain and De-...

Here is a list of the most relevant facts and assumptions regarding my concern: Monero is a POW (proof-of-work) cryptocurrency. A risk of POW cryptos is the 51% attack, which is possible when a bad ...

Elliptic curve cryptography, which is used in Monero, is vulnerable to QC. Would Monero be more vulnerable than Bitcoin, because the addresses contain public keys, not hashes of public keys? What ...
