BiblePay (BBP) Will Adopt the RandomX Algorithm on March 24th

18, Mar 2020

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: rx.biblepay.org. 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. BiblePay (BBP) coins can be traded on the TOKOK crypto exchange.

Checking Out the Scala (XLA) Project’s Mobile Phone Miner

13, Mar 2020

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. If you are looking for crypto exchanges where to trade the mined XLA coins, you can go to Trade Ogre, Crex.

Monero (XMR) Has Successfully Switched to RandomX CPU Mining

1, Dec 2019

The expected hard fork of Monero (XMR) happened without issues and now the mining part is being done with CPUs (mostly) using the RandomX mining algorithm as opposed to CryptoNight R that was mostly GPU mined prior the fork. Currently the hashrate of the Monero network is around 500 MH/s with XMR drawing a lot of CPU mining resources from other crypto projects that were already unprofitable to mine anyway, so as a direct consequence some of these might become interesting for mining again with the focus on Monero. The big question at the moment is where all the GPU mining power that was focused on Monero will go now as these were mostly AMD mining GPUs, so most likely other CryptoNight-based projects will have to deal with the extra computing power. After checking a few of the more popular CryptoNight-based projects we don’t yet see big jumps in terms of hashrate after the fork of Monero, and that could easily mean that XMR already had a lot of “free” CPU mining going on even on the old CryptoNight R algorithm.

With the current network hashrate of about 500 MH/s the estimated daily coins you can mine with a single AMD Ryzen 5 3600 CPU that has about 6 KH/s of hashrate on stock settings is around 0.019 XMR at the moment or a bit over $1 USD if you exchange it for fiat at the current rate. This is better than we could get with the same CPU mining other RandomX coins yesterday. It is about double than mining LOKI yesterday, which was the most profitable one using the RandomXL algorithm, today however things also look different for LOKI as the mined equivalent is actually more profitable than Monero at $1.28 USD with the current difficulty after the outflow of hashrate to XMR. ArQmA (ARQ) is also up almost double in terms of mined equivalent in USD, and WoWnero doesn’t seem to be much affected in any way, remaining the least attractive of the RandomX crypto pack.
