The Scala (XLA) project, formerly know as Torque (XTC), and Stellite (XTL) prior to that, may have some controversy surrounding it along the way, but we are not going to be talking about that. The project has just released their Scala Mobile Miner v1.0.0 intended for Android smartphone owners to mine XLA on their devices and we just wanted to give it a go and see how it works, but more of that in a moment. Scala (XLA) uses the s called DefyX algorithm for mining. DefyX is a customized hybrid algorithm combining RandomX, Kangaroo12 and Yescrypt with the memory requirements optimized to fit more energy-efficient CPU and ARM architectures according to the developers. Apart from Android smartphones that can just now be used to mine Scala (XLA) coins, you could use a normal computer processor to mine with significantly higher hashrate for quite some time already.

Let us take a look at the Scala Mobile Miner software that you need to download directly as an APK for the moment and manually install as it is not yet available on the Google Play store. We like the fact that the apps starts with a warning message noting the important things regarding the battery and CPU having a high load on your smartphone. Then at the Settings screen there are the options for how many of the CPU cores to use and what temperatures to maintain as safe for both the processor and the battery. Then all you have to do is choose a mining pool and set your worker or wallet for the pool in order to start mining.

Now as far as mining is concerned you should not expect too much from a smartphone, even if it is top of the line Android smartphone. We have tested with Huawei Mate 30 Pro and got around 50 H/s as hashrate with 4 out of the 8 CPU cores active. If running with full 8 cores the CPU thermal threshold of 65 degrees Celsius is reached immediately, not to mention that you still would want to be able to use your phone while the miner is running on the background. With 4/8 CPU cores for mining it is possible, not draining that much battery and keeping reasonable operating temperatures for both the processor and battery.

So in short we like the Scala Mobile Miner, it is well made and works fine maintaining the safety and usability of your device. As far as performance is concerned, well there is more to be desired, especially if you compare the hashrate of just around 50 H/s to a high-end desktop CPU such as Intel Core i7 6850K or AMD Ryzen 3900X like we did and you can see the results below:

Intel Core i7 6850K (6C/12T):
– XLArig 5.0.1 – 2100 H/s
– SRBMiner-Multi 0.4.0 – 4650 H/s

AMD Ryzen 3900X (12C/24T):
– SRBMiner-Multi 0.4.0 – 11970 H/s

The latest official XLArig 5.0.1, based on XMRig, is not the best performing miner at the moment with support for the DefyX algorithm used by Scala (XLA). You should opt out for the latest SRBMiner-Multi 0.4.0 significantly better hashrate for mining Scala (XLA) using the DefyX proof of work algorithm. Do note that the DefyX algorithm has been used for a while already by the Scala project and prior to that XLA coins were mined using CryptoNight algorithm, so it is both not a new project and not a new algorithm.

The latest SRBMiner-MULTI CPU and AMD GPU Miner version 0.2.0 has added support for another RandomX variant, namely the RandomV algorithm (MoneroV) as well as some additional tweaks, you can find the full changelog below. The previous release has also added support for the RandomSFX algorithm (SafexCash), so you can say that there is revival for CPU mining lately centered around RandomX, unfortunately that also has some negative side effects such as botnets mining. We’ll see how things go and for how long RandomX will remain in the CPU mining domain only with the growing interest around it and with many different variations becoming available as well.

SRBMiner-MULTI CPU & AMD GPU Miner 0.2.0 beta changelog:
– Added RandomV algorithm (MoneroV)
– Added –randomx-use-tweaks, to select the MSR tweak/s to apply
– Added RandomX tweak support for Intel Core2 processors

The latest SRBMiner-MULTI CPU and AMD GPU Miner version 0.1.8 brings support for a number of additional new algorithms (yespower variants) as well as pool mining for the Kadena algorithm (check the icemining pool) along ith some fixes. We have noticed that on Intel CPUs RandomX mining with all available threads does seem to make the system a bit unresponsive and lagging, something that was not the case with the previous version and that can cause some issues when trying to remote control the mining system for instance. Other than that the addition of new algorithms is always welcome, the full changelog of the latest release is available below.

SRBMiner-MULTI CPU & AMD GPU Miner 0.1.8 beta changelog:
– Added Kadena algorithm (pool mining only)
– Added yespoweric algorithm (IsotopeC)
– Added yespoweriots algorithm (IOTScoin)
– Added yespower2b AVX support
– Fixed nicehash protocol compatibility with rpc2
– Miner now won’t quit if not enough free RAM for an algorithm, it will just warn the user
