Are You Ready for the Ravencoin (RVN) Fork to KAWPOW Algo

5, May 2020

With just 1 day left until the hard fork of Ravencoin (RVN) to the new KAWPOW algorithm everyone that is planning to mine the cryptocurrency once more should be well prepared. There are already a number of miners supporting the new algorithm available, as well as some test pools where you can test and setup your GPU mining rigs for optimal performance. The Mining Rig Rentals service for leasing and renting mining rigs has just added support for KAWPOW rigs, but NiceHash has not yet added support for the new algorithm, so no massive hash going on and off on the RVN network after the fork. The KAWPOW algorithm is a variation of ProgPow and the available miners are offering very close performance, so the deciding factor in choosing should be what you are more familiar with and what works better for you (has less fee, or no dev fee at all, is open source or not etc.). Users with Nvidia GTX 1080 Ti might benefit the most from the new algorithm to be used by RVN, AMD owners with one of the most popular Radeon RX 480/580 GPUs might not be too happy whit the hashrate they will be getting (about half of the GTX 1080 Ti). KAWPOW is more GPU intensive and not affected by the video memory that much, so the more powerful the GPU, the higher the hashrate.

AMD Radeon users are significantly limited in their choice of mining software for the KAWPOW algorithm at the moment as there is essentially just one option available – the closed source NBMiner with 2% dev fee for KAWPOW that also supports Nvidia GPUs. The only opensource miner with no dev fee is the official kawpowminer that only works with Nvidia GPUs for the moment, though AMD support will hopefully be also added. The other KAWPOW miners are all closed source and work only on Nvidia GPUs for the moment, these are GMiner with 2% dev fee, T-Rex with 1% dev fee and TT-Miner with 1% dev fee. Our preferred choice out of these miners at the moment is T-Rex for Nvidia GPUs, though we are still waiting to also see an updated release of the z-enemy miner, so our preference may change in the future. We are also hopefully soon going to start seeing some additional optimizations to help differentiate performance from different miners at least a bit more…

Verus Coin (VRSC) VerusHash 2.1 Algorithm Mining With CPU

3, May 2020

Verus Coin (VRSC) is an interesting crypto project available for a while already that offers a hybrid PoW/PoS mode of operation, so you can mine and stake VRSC coins. The idea of the project and its custom VerusHash algorithm is to be mined with CPU and even though GPU miners do exist for the algo, they do not offer a performance advantage over a powerful processor. Near the end of last year Hashaltcoin FPGA mining support was made available publicly for the VerusHash algorithm with much better efficiency compared to existing CPU/GPU miners and that quickly drove away regular miners. This required a revision of the mining algorithm and the latest VerusHash 2.1 made FPGA miners unable to be used and brought back CPUs as the main choice for mining.

The preferred choice for mining Verus Coin (VRSC) is with CPU and the miner you need is called hellminer, or alternatively you can try with nheqminer. Hellminer is the faster, but closed source even though there is no developer fee it is limited to a single pool only – LuckPool, available for Linux and Windows, so you might want to go for it first. The Nheqminer miner fork (about 10-20% slower compared to hellminer) for VRSC is a bit slower in terms of performance, but is open source and available for Linux, Windows and MacOS and can work with all of the available mining pools.

As already mentioned there are miners for GPUs as well, but they do not offer performance advantage over CPU mining, in fact a multi-GPU mining rig might offer similar or slower performance to a higher-end processor, but with a much higher power usage. So while it is not very reasonable to mine VRSC with GPUs, you can at least try to see what your hardware is capable of and how it relates to CPU performance. There is a ccminer Verushash fork available for Nvidia GPUs as well as AMD Verushash miner available for AMD GPUs.

As far as performance is concerned, AMD’s latest generation Ryzen CPUs do seem to have some advantage over Intel processors, but in general the more cores you have, the better hashrate you can expect to get. Ryzen 3900X (12C-24T) does about 30 MH/s, while an Intel 6850K (6C-12T) does manage to get you just about 11 MH/s hashrate. As a comparison a GPU mining a GTX 1080 Ti does manage to get you just about 6 MH/s per GPU, so as we’ve explained it might not be very wise to mine VRSC with anything other than a higher-end processor, although it is possible to also use GPUs from AMD and Nvidia.

If you need a mining pool where you can try mining Verus Coin (VRSC), then you probably want to head on to Luckpool where most of the hashrate is currently located, alternatively you can try Lepool or Zergpool. The largest pool LuckPool has some nice features to miners such as awarding the block finder with a fixed reward as well as a hybrid solo mining mode where you still get rewarded even when not finding a block yourself. VRSC is currently traded on multiple smaller crypto exchanges such as SafeTrade, STEX, Graviex, AAcoin, Kuang Exchange.

Mining ZANO Using the ProgPoWZ Proof of Work Algorithm

22, Apr 2020

The Zano (ZANO) crypto project is relatively new, launched last year, as a hybrid PoW/PoS coin aimed at e-commerce related applications according to the developers with 1 ZANO block reward. The project executed a 1:1 Boolberry (BRR) coin swap, but what seems to be most interesting about it is the fact that it is the first coin to use a ProgPoWZ as a mining algorithm (based on ProgPoW) and as far as we know it is still the only one to use it. Even though it is one of the early ProgPoW-based projects out there it still does not seem to have attracted that much interest from users or have a very large user base. What attracted our attention is the fact that ZANO has just been added to Whattomine and you can track mining profitability easily there, though currently not in the first few in terms of profit.

ZANO can be CPU mined (pointless at the moment) or mined using AMD OpenCL or Nvidia CUDA GPUs and it is also available on MiningRigRentals where you can rent mining rigs offering ZANO hashrate or lease your own hashrate for others to mining ZANO. There is a Progminer fork (source) with support for ProgPowZ as well as official precompiled binaries for CPU, AMD GPUs and Nvidia GPUs and ProgPoWZ has also been supported for a while now by TT-Miner – a closed source miner for Nvidia GPUs with 1% developer fee. Performance wise TT-Miner does seem a bit faster compared to the Nvidia CUDA progminer, 23 MHS (TT-Miner) vs 21.5 MHS (progminer) on GTX 1080 Ti.

ZANO currently hovers a bit below the 500th place according to CoinMarketCap and is being traded on a few smaller exchanges with 4.4 Million USD market cap and almost 1% of that as daily volume at the moment. ZANO is available for mining on two mining pools with almost 95% of the hashrate focused on Lukypool and the remaining hashrate on Fairpool. If you are familiar with ProgPoW mining then mining ZANO should not be much different with its ProgPoWZ algorithm, and even though the two algorithms are not entirely the same you can expecte to get pretty much the same performance as hashrate on both algorithms with your mining GPUs. Just like with ProgPoW here there is also a fairer performance balance between AMD and Nvidia GPUs based on the level of the GPU you have available – lower-end video cards will be slower for both the red and the green camp, while higher-end will be faster – no unfair advantage due to different video memory specifics as the algorithm is actually more GPU intensive compared to Ethash for instance. The following to crypto exchanges offer support for ZANO trading at the moment: Stex, qTrade and Trade Ogre.
