Questions relating to the RandomX proof-of-work (PoW) algorithm used by Monero.

RandomX is a proof-of-work (PoW) algorithm that is optimized for general-purpose CPUs. RandomX uses random code execution (hence the name) together with several memory-hard techniques to minimize the efficiency advantage of specialized hardware.

What is so different about RandomX from other attempted ASIC-resistant mining algorithms?

I read that the original Cryptonight hashing algorithm was optimized for the L3 cache of a modern CPU, giving CPUs as large of an edge as possible. I've also heard that RandomX effectively turns a modern day CPU into the most effective mining tool -…

Mining questions

I am trying to write a miner for myself. I understand I get the block template and then hash the block hashing blob. That gets me a hash. Do I then append it to block hashing blob or something else in order to submit? Take this example:…

What pool miners exist that can mine RandomX?

In a couple weeks from now, Monero will start using the RandomX PoW algorithm, replacing the current Cryptonight-R. What are the current pool miner software that may be used to mine with this particular algorithm, so that a current miner may use to…

Optimizing xmrig

I am mining Monero with xmrig 5.11.1. I am using an AMD Ryzen 1950 cpu on Ubuntu Linux 20.04. I am trying to optimize my mining. This is the output of the “h”. It shows an “anomaly” in threads 12, 13, 14, and 15. Their hash rate is much higher, 380…

What's the easiest way to create a unique job for every worker of monero mining pool?

There are several mining pool servers. Each server polls monerod for a new job. I want to generate a unique job on each server for all the workers of my distributed pool. It is very important to note that I want to generate unique among all my…

How can I create a simple private pool for tracking hashes for me and my friends trying to mine a block by ourselves?

For context, me and my friends have assembled a little mining group for fun and we currently mine whatever is most profitable on cpu and gpu to the same address on the same pools. I programmed a little discord bot that runs on my home server to use…
