RandomX VS RandomxAudits

This is not true for all crypto coins. A small proportion of mining hash functions are deliberately designed to thwart ASICs, e.g. https://github.com/tevador/RandomX. It's a cat-and-mouse game, though: CryptoNight was designed to fulfill the same role, but ultimately failed: https://monerodocs.org/proof-of-work/cryptonight/.

Can we reference this specs doc from the Randomx repo https://github.com/tevador/RandomX/blob/master/doc/specs.md . I am going to be using the variables K and H as described in the doc.

Monero uses randomx, an ASIC-resistant and CPU-friendly POW algorithm created by Monero community members, designed to make the use of mining-specific hardware unfeasible. Monero previously used CryptoNight and variations of this algorithm. More info in the GitHub repo.

Here's the randomx github. Or at least I think its the same randomx that xmr uses? https://github.com/tevador/RandomX. There's some stuff in there under the documentation section.

Monero does not have ASICs since RandomX was implemented in 2019. CPU is the best way to mine it. See https://github.com/tevador/RandomX.

Tor recently released a DoS mitigation feature for Onion Services using a Proof-of-Work (PoW) scheme. The PoW algorithm used is Equi-X which was created by tevador, who you may know from Monero's RandomX.

It would seem though that you can have PoW without ASICs. RandomX has been successfully resisting ASIC, FPGA, and GPU mining for about 3.5 years now.

The term for describing is memory hard functions. RandomX[0] is one such example where GPU parallelism does not net them a large advantage over CPUs.

I don't know of any existing C# implementations, but for RandomX you can get the spec from RandomX's Github page.
