Can someone suggest a better way to test transfers for development testing?

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 ...

Post quantum signature scheme integration in Monero

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 ...

How would the privacy of monero be affected by a quantum computer?

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-...

Is there a formal plan in place for the transition to Quantum Computing? If so, what is it? [closed]

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 ...

How vulnerable is Monero to Quantum Computing?

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 ...
