Grin is a new crypto project for creating a the private and lightweight mimblewimble blockchain that would provide electronic transactions for everyone without censorship or restrictions. The algorithm that Grin uses is Cuckoo Cycle with 1 minute block time, 60 GRIN block reward and no limit on coin supply or reward halving. There is not going to be any ICO, founders reward, pre-mine or masternodes available for this project, so people that do not like any of these should be Ok with this project. Miners for Grin are still currently being developed, although there are some already announced or available, though initially it could be a bit of a challenge to make things work with the right miner and pool. For instance the official MWGrinPool is currently not taking new registrations, though new pools should be available as alternatives. There are already a couple of options for pools on the Testnet where you can test the mining before the Mainnet launch like Spark Pool.

The official open-source Grin Miner software is currently only available for Linux and Mac OS X and it supports both CUDA and OpenCL mining. For miners looking for Windows miners there is the Grin Gold Miner (with 1% fee for the Grin Development Fund and 1% fee for further miner development), although it also works with Linux) that supports all AMD and NVIDIA 8GB cards (requires a GPU with 8GB VRAM!). Do note however that Nvdia RTX 8GB cards need Linux or Windows 7 due to memory addressing issues. RTX 2080 and RTX 2080 Ti are fastest in terms of performance if you manage to make them work, OpenCL code for AMD cards is currently still being optimized. Cheaper slower Celeron CPUs are not recommended for many cards on the system (similar to Merit and BITC that also use the same algorithm for mining). Another alternative for Windows miners should be the GrinPro Miner that is not yet available for download and that will have 2% developer fee. This miner should work on AMD and Nvidia GPUs with 8GB VRAM, although it promises upcoming support for 6GB VRAM cards as well, so that could be interesting for some users.

Unfortunately zjazz, who was pretty active in miner development for Cuckoo Cycle support for Merit and BITC hasn’t updated his miner for a while and will probably not be supporting Grin mining at least for the moment. The latest version of Bminer that was just made available however also comes with experimental support for mining Grin, so you might want to check it out as well. Do note that it is a closed source miner with 2% developer fee, so have that in mind as well when checking out different miners for Grin.

ProgPoW or Programmatic Proof-of-Work can be seen as the successor of the Ethash algorithm with enhanced ASIC resistance and while it has been available for a while there hasn’t been that much going around the new algorithm up until recently. The fact that Ethereum (ETH) is considering the switch from Ethash to ProgPoW in the near future has sparkled interest in the algorithm and we may soon start seeing more coins and miners talking about the use of that particular algo. Some of you might remember that Bitcoin Interest (BCI) was the first crypto coin to switch to the ProgPoW a couple of months ago. And while BCI hasn’t been doing that well actually, before or even after the fork to ProgPoW, it is still interesting to note that it was the first to use it and it also provided pre-compiled binaries of the initial miner for ProgPow.

Meanwhile there hasn’t been that much alternative miners up until recently that had support for ProgPow, probably due to the fact that further significant optimizations in terms of performance might not be possible for the available mining hardware. One of the more recent and not very popular yet miners available with ProgPoW support is TT-Miner, a closed source miner with 1% developer fee available only for Windows and working only on more recent Nvidia GPUs. TT-Miner (TradeTec Miner) also supports Ethash, UBQhash and MTP aside from ProgPoW and in our limited experience it has performed pretty good on a variety of Nvidia GPUs.

Another really fresh ProgPow miner that was just made available and that apparently needs more work is Progminer. It is forked from Ethminer and the source is available along with compiled binaries for Windows and Linux, do note that there are separate pre-compiled binaries available for AMD and for Nvidia GPUs, so make sure you download the correct one. This is probably the best miner to go for at the moment for ProgPoW specs wise, unless you have some trouble making it work on your particular hardware as we have encountered some issues already… Feel free to report your issues (if you have) and what performance running any of these ProgPoW miners in the comments below.

We have beeing playing for a couple of days with one of the new reference design Nvidia RTX 2060 video cards and tried how well it performs for crypto mining using various miners and mining algorithms and as expected with new GPU releases there is more to be desired, but more on that in a moment. We like the design and implementation of the whole cooling solution from Nvidia on their GeForce RTX 2060 Founders Edition cards, though there will be a lot of custom partner designs as well. The later should be available in a couple of days as well and start hitting the market pretty soon by the time Nvidia starts delivering FE cards in a couple of days. One thing that we don’t like very much with the latest RTX 20×0 series is the fact that the Founders Edition cards are only being sold directly by Nvidia and only available in a limited number of countries worldwide and the same goes for the RTX 2060 FE.

The Nvidia GeForce RTX 2060 Founders Edition is equipped with a single 8-pin PCI-E power connector (up to 150W power) plus the maximum power provided by the PCI-E slot (max 75W) which should offer enough headroom for additional overclocking over the stock 160 W TDP (100%). You can go up to 118% TDP or about 189 Watts with a tool like MSI Afterburner on the FE. We are yet to play a bit more with the overclocking capabilities of the video card’s GPU as well as the onboard GDDR6 memory, even though the memory bus on the RTX 2060 is just 192-bit the fast 14 Gbps GDDR6 video memory still manages to provide pretty high memory bandwidth. The cooling solution and the fans are doing good job at keeping the video card at below 60 degrees Celsius operating temperature even under 100% load with 160W TDP with 30 degrees ambient temperature. The cooler is well built with high-quality and durable fans, so this should ensure long lasting and problem free operation as we are used to with FE cards unless there is some factory issue or a design flaw, something that unfortunately can always happen.

In the table above you can see some of our initial tests with various miners and using some of the different algorithms they support. As expected with the GPU releases the miners are not yet optimized or may even not support the new GPU at all like in the case of Bminer that spits out an error regardless of the algorithm. Other miners tend to crash on certain of the supported algorithms when ran on the RTX 2060 with the default settings. Since it is a new GPU after a bit of time we can see additional performance boost when the new video cards hit the market and miner developers get access to them and start playing around. For now the new RTX 2060 does not seem very attractive for crypto mining, but hopefully soon it will be better supported and offer even better hashrates. Until we also see some more positive move and the crypto market starting to recover however the demand for the new RTX 20×0 series and not only for the RTX 2060 probably won’t be big for sure.

Nvidia has announced their new mid-range GPUs, namely the GeForce RTX 2060 as the fourth GPU in their new RTX range following the release for RTX 2080 Ti, RTX 2080 and RTX 2070 that are already available on the market. Specifications wise the new RTX 2060 is something in between the GTX 1060 and GTX 1070 from the previous generation, along with the new Tensor and RT cores on top of the CUDA cores. As far as crypto mining goes however there is not much use of the new gaming technology built into the RTX graphics cards, but the new architecture does bring some extra performance as we have already seen with he earlier RTX models… especially with miners already getting optimizations for the 2000 series.

It will be interesting to see what kind of performance you can currently get from an RTX 2060 GPU and we are soon going to have some results to show, so stay tuned for more information. Meanwhile the new GeForce RTX 2060 should be available from January 15th with prices starting at $349 USD. It is pricier than what the GTX 1060 was released at its launch, but then again you are also getting more with the GeForce RTX 2060, will the extra features be worth the price for mining though, that is entirely different question. With the current low profit for GPU mining that has been going on for quite some time already it is hard to justify the purchase of new mining hardware…

Ledger has announced their new crypto hardware wallet named Ledger Nano X and have started taking pre-orders for the new device. The new Ledger Nano X is a Bluetooth-enabled hardware wallet with built-in battery that will be able to also connect to your smartphone and not only to your computer as was with the previous generation Ledger Nano S. According to Ledger the new wallet promises better security, even with the wireless connectivity option, as well as an improved user experience and design. Ledger also launched the Ledger Live Mobile app, which allows Ledger Nano X users to manage secure transactions, install and uninstall apps, and check their real-time balances on the go. It will also enable Ledger Nano S users to check their balance in read-only mode. Ledger Live Mobile will be made available in the App Store and Google Play on January 28th.

The new Ledger Nano X has a Bluetooth feature that easily and reliably connects through the Ledger Live Mobile app, which allows users to connect the device to their smartphone, providing increased mobility without sacrificing security, though we are still a bit concerned about the wirelesses connectivity option. The new Ledger Nano X can store up to 100 crypto assets from more than 1100+ supported, which is six times more capacity than the Ledger Nano S, and includes an improved interface with a larger screen to make things easier for the user. The Ledger Nano X costs $119 USD to pre-order now and shipping is expected to start in March.

The latest T-Rex Nvidia GPU miner version 0.9.1 adds support for two new algorithms – X16RT (Veil) and SHA256Q (Pyrite) and comes with some minor performance improvements for x16r, bcd, x22i and other x16-like algorithms. There are also multiple web monitoring page improvements introduced, along with a Linux watchdog as a windows one has been available for a while already. Everyone currently mining Veil that uses the new X16RT algorithm might be interested in switching to T-Rex 0.9.1 as it seems to be even faster compared to the recently released CryptoDredge 0.16.0 miner that also added support for X16RT.

Do note that the T-Rex is a closed source miner with 1% development fee built-in. Also make sure you have a recent video driver installed (the latest for CUDA 10 support) as the binaries for both Linux and Windows are compiled for CUDA 9.1/9.2/10.0.

For more information and to download and try the latest version of the T-Rex miner…

The latest CryptoDredge Nvidia GPU miner version 0.16.0 comes with added support for the new X16RT algorithm being used by the recently launched Veil project that introduced the new algo. There is also support for the new Lyra2zz algorithm that is being used by the LAPO project, if you are interested in checking it out as well. The latest version also stabilizes the MTP algorithm hat is being used by the Zcoin project. If you are mining XZC or Veil with other miner at the moment you might want to try the latest CryptoDredge release as it is well performing and stable, working better than other alternates, not to mention it is the fastest one for the X16RT algorithm at the moment.

Do note that the CryptoDredge miner supports only Nvidia GPUs and is a closed source software that comes with 1% built-in developer fee for all supported algorithms, however the dev fee is 2% currently only for MTP mining (Zcoin), there are binaries available for both Windows and Linux (CUDA 9.1/9.2/10.0).

After a bit of a delay the official launch of the Veil Project happened earlier today and you can already mine VEIL coins if you are looking for something new and interesting to move your GPU mining rigs on to. Veil is the first Zerocoin-based cryptocurrency with always-on privacy thanks to combining Zerocoin and RingCT technologies to provide full-time privacy without compromise. Veil’s blockchain is secured via Proof-of-Work and Proof-of-Stake, though initially only 50% of the coins (50 VEIL) are going to mining/staking and the rest is distributed among the founder, Veil Labs for ongoing research and development and Veil operations budget, funding operations activities such as core network and wallet development, project management, online user support, bounties, marketing and partnerships. You can check the official Veil Project website for full details and additional information about the project.

The Proof-of- Work algorithm is X16RT, based on the X16R algorithm introduced by Ravencoin, but with modifications so it requires a new specific miner and such are already available for both AMD and Nvidia GPUs. Miners with Nvidia-based mining rigs can download and use the latest supminer 2.0 that supports X16RT algorithm and AMD miners can go for the latest WildRig Multi 0.15.0.8 mtp x16rt that has also added support for the X16RT algorithm with more miners probably going to follow soon enough with support for the new X16RT algorithm. If you are looking for a mining pool, you can currently go to the https://veil.suprnova.cc/ as the first pool to support VEIL with others probably following soon as well.
