One Day Left Until Monero (XMR) Hardfork to RandomX

29, Nov 2019

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

ArQmA (ARQ) Has Forked to a New RandomARQ and Results Are Interesting

11, Nov 2019

We have already mentioned the plans of ArQmA (ARQ) to fork to a new RandomX-based algorithm called RandomARQ and that has happened a few days ago and we have tried CPU mining the new algorithm. Since it is based on RandomX we expected to see significant advantage for the latest AMD’s Ryzen CPUs like we’ve seen with RandomX and some other variants of the algorithm used by other projects. To our surprise however Intel’s multi-core processors are actually not that far behind in terms of performance (a few times slower like on RandomX). Of course Intel is still slower, but the actual difference is not as much as we’ve seen so far and that is definitely good news for miners that have some spare Intel CPUs that might be interested in mining something based on RandomX.

We have tested performance using the latest XMRig miner and SRBMiner-MULTI miner with the seond one still performing slower as we have seen with other RandomX algorithms compared to XMRig. With an AMD Ryzen 3600 using XMRig we are getting around 22.8 KH/s while on Intel Core i7 6850K CPU we get about 17 KH/s, both being 6 core – 12 thread processors though the AMD one is much newer product. With SRBMiner-Multi the results were 13.4 KH/s with the AMD and 7.8 KH/s for the Intel CPU, so you better stick to XMRig for mining ARQ for now and you might want to also test your Intel processor(s) as well for the RandomARQ algo. The not so good news however is that profit for a single CPU mining ArQmA (ARQ) is well nonexistent, unless you do not pay for electricity… 20 USD cents per day for the Intel and 30 for the AMD processors. These dayly earnings could probably just cover your electricity costs if you have cheap electricity at 10 USD cents per kilowatt.

ArQmA (ARQ) to Fork to a New RandomX-based Algorithm in November

10, Oct 2019

ArQmA (ARQ) is another crypto project that has revealed plans to fork to a new RandomX-based algorithm called RandomARQ. This project has been started in 2018, but is still wit pretty low market capitalization and low trading volume according to data from CoinMarketCap, so there is much room for growth. The ArQmA (ARQ) fork to the new RandomARQ algorithm is currently planned for 8th of November at 23:50:00 at block 303666, though this might not be the final date. The latest XMRig v4.3.0-beta had just added support for the new RandomARQ algorithm with “rx/arq”, so you should be good to go by the time the fork happens should you decide to check out the project. Currently ArQmA (ARQ) uses the CryptoNight Turtle algorithm, so it is still mineable with GPUs. Since RandomARQ is based off RandomX it will be CPU friendly algorithm, so mining after the fork will be done mostly with CPUs due to the fact that the algorithm has been designed to be processor friendly and not GPU, ASIC or FPGA friendly. Some good crypto exchanges to trade ArQmA (ARQ) coins include Citex and Crex.
