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.

Luxcore (LUX) project also known as LUXCoin previously has announced their plans for an upcoming fork that will replace the currently used PHI2 algorithm to a new one called RX2 (essentially a variation of the lately popular RandomX algo). RX2 is Luxcore’s version of RandomX that has some small modifications to the RandomX parameters in order to suit some specific requirements (details are not yet revealed). The exact date for the introduction of the new algorithm has not been revealed yet, so it is sill “in the coming weeks”. This marks yet another crypto project that is going towards the RandomX algorithm in order to fight with FPGA and ASIC miners.

Since the RX2 algorithm is based on the RandomX it will also be more CPU-friendly for mining (will require a separate miner support apparently) as it will not work with any of the miners that currently support RandomX. It seems that so far the RandomX algo favors AMD’s latest multi-core Ryzen 3 CPUs in terms of performance over Intel’s products that are much more widely spread and used mostly by miners in the last years. This could help AMD’s sales of new processors if mining for RandomX picks up and offers decent profitability which is still not the case for the moment. If more projects move towards RandomX or variations of the algorithm, like LUX is apparently doing, the interest and prfoitability might as well skyrocket and spark a new wave of CPU mining oriented rigs to be built.

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.
