Let's say I have quantum computer - How do I mine BTC?
For the sake of argument assume I have 10.000 qubit quantum computer, not via extensive hardware, but with math & algo on a classcial computer. I have reversible engine with both Clifford and Non Clifford gates. Now, how do I mine BTC and win in proof of work? Don't tell …

SHA256 collision: The Kaoru Method
I don't think I know enough to comment on this, hence posting here [The Kaoru Method: Linearizing SHA-256 via Universal Fractional Space Mapping and Carry Reconstruction](https://osf.io/jd392/overview) More: - [Unexpected 186-bit SHA-256 quasi-collision: Is this mathematically possible with consumer hardware or is there a flaw in my verification script?](https://crypto.stackexchange.com/questions/119199/unexpected-186-bit-sha-256-quasi-collision-is-this-mathematically-possible-with) - [Is …
Scholar Labs for Crypto?
Has anyone tried out Scholar Labs for crypto research? Is it any good?
Prime Sieve as Bits
In ancient of days (circa 1987-ish), I had coded a modified Sieve of Eratosthenes where single bits (rather than bytes) served as primality flags. Further, the mapping was such as to contain no bit addresses for multiples of 2, 3, and 5. It ran slow, but had the advantage of …
Concept for random numbers...
Just this morning a means occurred to me for how I might generate a most extremely unpredictable pseudo-random number for encryption purposes. 1. Get the Nth pseudo-random from a fixed seed. 2. Permute it into a 64-element Knapsack key. 3. Obtain the next-in-sequence pseudo-random. 4. Encrypt that with the key …

SHA-3 hardware acceleration
Does anyone know if proper SHA-3 acceleration is on the horizon for server and consumer hardware? Right now AFAIK only z/Arch has SHA-3 fully implemented in hardware, other architectures only have specific instructions for speeding up particular operations used within SHA-3. With Sphincs+'s performance being so heavily tied to the …
A new secure random number generator
Hi everyone, I'd like to share an secure crypto random number generator I created. I'll keep this post short and sweet so here are the links... PDF about the algorithm: [https://www.gsjournal.net/Science-Journals/Research%20Papers/View/10393](https://www.gsjournal.net/Science-Journals/Research%20Papers/View/10393) Source code in Java on GitHub: [https://github.com/wgilreath/CHARIBDIS](https://github.com/wgilreath/CHARIBDIS) I had posted before, but did not see it in the posts …
