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.

Kadena (KDA) is a few years old startup company with serious financial backing that has just recently launched their public blockchain and it promises some interesting things including support for tens of thousand transactions per second with multiple blockchains. Kadena is supposedly offering a blockchain that is faster, more secure, and more scalable than other crypto projects and on top of that it is being done with Proof of Work, so mining is possible for anyone that might be interested. Kadena also supports smart contracts and comes with its Pact smart contract language described as the first truly human readable smart contract programming language that should be easy to be used by more users and not just advanced programmers.

For the moment Kadena can be mined only using CPU, no GPUs, FPGAs or ASIC miners, so good news for anyone with some CPU resources that can be utilized for mining. The not so good news is that for the moment the chainweb-node and miner used by Kadena is still only available for Linux and Mac OS users only, so no Windows binaries are available. This means that you cannot yet run a full node or mine if your mining rigs are running Windows OS or even if you are running on most of the specific Linux-based OSes for mining, unless you add the required support yourself. Here you can read more on mining for the Kadena Public Blockchain if you are interested. Mining is either done by running a local full node or with a remote node supporting mining and just the miner software that is packaged inside the chainweb-node.

The Gulden (NLG) crypto project, an older one available for a few years already originally based on Scrypt Proof of Work algorithm, has switched the mining algorithm. Their new PoW algorithm targeted at CPU mining is called SIGMA and is designed to be ASIC/GPU resistant. The goal of the algorithm switch is to also attract new miners and users for the project as there hasn’t been much development for Scrypt mining for quite some time and mining hasn’t been largely become unattractive for a lot of users not having ASICs and cheap electricity.

SIGMA or Semi Iterated Global Memory Argon is a new and unique algorithm developed for NLG. The algorithm is designed to require more memory, making it impractical for implementation by ASICs rising the price, but not entirely impossible. It is also complicated to make fast hashing parallel on GPUs to achieve much faster performance than on CPU, so CPU mining for now is the only option for mining Gulden coins. It seems that CPU mining is getting a lot more attention lately with RandomX as well and other algorithms like SIGMA.

Moving back to CPU mining means that everyone with a low, or mid to high-end CPU will be able to mine new NLG coins, for the moment there is no pool mining for SIGMA and NLG. Mining is SOLO and done through the official local wallet, so for mining you need to download the latest version and you need to update it anyway if you had some Gulden coins stored in a wallet prior the fork. So make sure you update to the latest available version as there have been some fixes in the last few days after the fork happened on October 16th that fix issues.
