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

The latest GMiner 1.80 miner adds support for the Cortex algorithm used by the Cortex (CTXC) AI on Blockchain crypto project as well as support more Ethash coins along the recently introduced support for Ethereum: Pirl (PIRL), Callisto (CLO), Metaverse (ETP) and Expanse (EXP). Do note that the DevFee on the Cortex algorithm is currently set at 5%, which is higher compared to the regular 2% for the other supported algorithms, though this is to be expected since the official Cortex liner is only for Linux and GMiner seems to be the first with Windows support. When mining Cortex if you get a weird “Write timed out” error you might need to lower the intensity from the default 100 value, use the -i option with a value for each GPU separated by space (single value will be just for the first video card). It also seems that the power usage for the GPU when mining Cortex is lower than the max TDP value at the moment (further optimizations possible?), so the mining video cards are using less power and run cooler.
The GMiner miner software was originally only an Nvidia GPU miner, although some algorithms are already supported on AMD GPUs as well. Do note that GMiner is a closed source miner for Nvidia and AMD GPUs with binaries available for both Windows and Linux, there is a 2% developer fee built-in the software.

A new website (registered just yesterday) has appeared for a company called ZXMiner claiming to be selling the first Nervos (CKB) ASIC miner for the Eaglesong algorithm. The website is in Chinese and the price for the ZX1 ASIC miner supposedly delivering 820 GH/s with 1100 Watts of power usage is 18000 CNY (Chinese Yuan) which is roughly $2560 USD (payments taken only in Bitcoin). According to the website the estimated shipping date is January 2020, meaning that they should have developed the hardware before the mainnet launch of Nervos that happened recently. We would advice to be extra careful with this as it may be a scam, even though it is apparently not targeted at non Chinese crypto users as the website does not have an English version.
Soon after the mainnet launch there have been news of FPGAs supporting the Eaglesong algorithm that the project uses and now there is information about a possible ASIC miner incoming, though you should treat that with extra caution. The ZXMiner ZX1 photo on the website is actually an edited photo of the MicroBT Whatsminer M3 ASIC miner with zxminer logo put on top of the device and doing that is never a good sign and definitely not a way to earn trust. We also don’t like this line of text “No refund or return after payment, regardless of whether it is shipped or not” as translated by Google Translate, so don’t be in a hurry with this ASIC miner!
