The BiblePay (BBP) project has announced they are going to be switching to the RandomX algorithm on March 24th, 2020, at block 184675. What is interesting here however is not only the switch to RandomX for PoW CPU mining, but the fact that the coin will support Dual Mining along with Monero (XMR), it is called BBP Dual Hash Mining and is in fact closer to merged mining. In theory, you will receive approximately 190% revenue for mining (more specifically, 90% in XMR rewards, and 100% of your hashpower in BBP rewards). Each RandomX hash has a full 100% chance of solving a BBP block (or a pool share), while each RandomX hash still has an equal chance of solving an XMR share.

There is a custom miner XMRig-BBP, based on XMRig, that you need to use in order to be able to take advantage of the BBP Dual Hash Mining feature and there is a new RandomX pool that will come on-line approximately 1 day before the fork goes live, the address will be: It definitely sounds interesting, though until the new pool reaches significant total hashrate it will be hard hitting Monero blocks often and that can really bring lower initial results. Still a novel idea and something different than just another hardfork to switch to RandomX as a mining algorithm.

Fore more details about the upcoming BiblePay (BBP) hardfork to RadomX…

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 DERO project is another crypto that last year had announced their plans to switch the mining algorithm to a RandomX variant and they are finally doing it. Tomorrow, March 7th at block 4550555, marks the time that DERO will be switching to the new CPU mining POW called AstroBWT. So if you are into CPU mining you might want to give it a try after the fork and see what DERO will do with the new algorithm. The project itself has been available for quite some time and has been in constant development, relying on the CryptoNight algorithm prior the upcoming fork to their new AstroBWT algorithm

AstroBWT is a CPU mining only algorithm and apart from the official miner for the algorithm, there is also the latest XMRig 5.8.x major release that added support for the algorithm a few days ago and the minor releases since then have improved it by fixing issues and significantly increasing mining performance. So make sure you try XMRig on your CPU mining hardware it time for the fork in order to be ready when the hardfork happens, that is if you do plan to try mining DERO with the new AstroBWT algorithm.
