Monero (XMR) will be hardforking tomorrow, November 30th, at block number 1978433. The fork will change the current CryptoNight R algorithm for mining to the new Random X PoW algorithm, essentially moving the mining of the coin to CPU. There are already a few RandomX miners out there that you can use, links below, and although some f them also support AMD or Nvidia GPUs, you would probably want to stick to CPU mining with RandomX as the algorithm is optimized for processors and GPU mining performance is far to low currently to be considered. Also as already noted AMD’s Ryzen 3000 series of processors is doing great for Random X and performance wise it is much better than recent Intel alternatives.

Another important thing to note regarding the upcoming for is if you are mining directly to an exchange using a paymentID. Since after the fork support for PaymentIDs will be discontinued, in order to continue successfully mining after the network update you need to also update your mining address. Alternatively you can just update to the latest v0.15.0.1 wallet and use a local wallet address for mining after the fork. For an up to date pools for mining XMR you can check the list at MiningPoolStats, they should all be ready for the fork by now.

Mining software with RandomX support:
XMRig 5.0.0
SRBMiner-MULTI 0.1.7
XMR-STAK-RX 1.0.0

The DERO project is one more crypto coin that plans to move from CryptoNight to the new RandomX algorithm most likely before the end of the year. The reason that is cided is to introduce more decentralization and participation to their platform with the move to the RandomX proof-of-work algorithm. Currently DERO can be mined using CryptoNight ASIC miners and this is something the developers of the project are trying to move away from and attract new users with the mining algorithm switch. The new RandomX algorithm should go live on the DERO testnet on October 31, 2019 and soon after that if everything works as expected we could see the main network forking to the RandomX PoW as well. Currently DERO is ranked around 500th place according to CoinMarketCap data with a market capitalization a bit below 4 million USD and has a daily trading volume of about 1/4 of the total capitalization.

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. More information about the RandomX algorithm from the official GitHub repository including a benchmark to test performance on CPU mining. Do note that RandomX dos manage to perform better on processors with higher number of cores and threads available and apparently is doing best so far on the latest AMD Ryzen series of CPUs. GPU miners are also available, however performance wise they are similar to what hashrate a lower-end dual core processor can provide, so they are not the best choice for the new RandomX algorithm for the moment.

Monero (XMR) will be once more changing its PoW algorithm for mining in an effort to attract regular miners CPU/GPU miners and drive away FPGA/ASIC miners. Testing on the private RandomX testnet has concluded successfully and RandomX PoW mining will move to public testing on the XMR testnet later today. There is quite some time left before the fork happens though, it is scheduled for block 1978433 that should hit sometime on November 30th, so there is time for you to get familiar with the new RandomX algorithm by then. If you are interested in checking out the performance of your CPUs, then you might want to check the official RandomX Benchmark app (link for download below). There is also a not so optimized OpenCL miner available that works on both AMD and Nvidia GPUs available as well, though performance might be disappointing compared to that of higher-end CPUs at this point.

It is interesting to note that the RandomX algorithm apparently favors CPU mining due to its design even GPUs might not do so well initially with it, though we are probably going to see better optimized GPUs miners soon enough. All in all this might make CPU mining attractive to miners around the fork date, though there are other factors to take into account as well, so we will have to wait and see. AMD’s Ryzen CPUs are doing particularly good in the initial benchmarks of the RandomX algorithm as it is already being used by the new project Epic Cash (EPIC). You can see that the AMD Ryzen 9 3900X is doing particularly good in terms of performance with its big number of cores and low power consumption, though it is also an expensive and still hard to find product.
