Grin Mainnet Launching Today, Are You Ready for Mining

15, Jan 2019

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. Some good places to trade GRIN include CoinEgg, Gateio, HitBTC and Bittrex.

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. The latest version of the closed source miner NBMiner has also just added support for the Cuckaroo algorithm used by Grin (both Windows and Linux), so you can give it a try as well (Nvidia only).

New T-Rex 0.7.2 Nvidia Miner With X22i Algorithm (SUQA) Support

28, Oct 2018

The latest version 0.7.2 for the T-Rex Nvidia GPU miner brings support for the new X22i mining algorithm used by the SUQA project. The even better news, besides the fact that another miner supports this new algorithm is that T-Rex 0.7.2 provides up to about 40% faster performance for X22i compared to the latest zjazz Nvidia miner that was previously the fastest in terms of hashrate. The SUQA coin has just reached its first planned block reward halving, so gaining some extra performance boost might be just what you need to keep things profitable on the longer term.

If you are mining SUQA on Nvidia GPUs, then it would be a wise idea to update from zjazz to the latest T-rex and continue mining it with significantly higher hashrate. If you are having stability issues with X22i mining you might try to decrease your overclock or play with the power limiter until you have the mining rig stable. 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.

SUQA an Interesting New Crypto Project With a New X22i Algorithm

11, Oct 2018

We love to see new crypro projects that also come with a new mining algorithms that are not dominated by ASICs or hashpower renting services. SUQA (now renamed to SIN) is one such new crypto project that comes with its own new proof of work mining algorithm called X22i that of course requires a new miner. The coins is a proof of work one, meaning that it can be mined with GPUs, although initially there was only an Nvidia CUDA miner available, there is now also an AMD OpenCL miner also available. SUQA has a block reward that goes down pretty fast initially, so it is apparently a good idea to join the mining early on with a higher block reward. There are also Time-Locked deposits with 5% regular APR, though for the first three months it is raised to 25% to drive early adoption. The most interesting thing about the X22i algorithm is the so called quantum resistant part in the algo chain called SWIFFTX and the promise that the project will remain FPGA and ASIC resistant.

Currently there is an official open source ccminer fork for Nvidia GPUs, though it is significantly slower than the third-party option available. The zjazz experimental CUDA miner with SUQA support is up to about twice faster compared to the official one. It is however still an experimental release, a closed source miner and comes with a 2% developer fee built in. A couple of hours ago zjazz has also released an experimental version for AMD GPUs, so now you can use it to mine SUQA on AMD-based mining rigs as well. There are already a big number of pools supporting SUQA mining, so you have a lot of options to choose from. There is a mining calculator, though you can use it only for checking how much coins you can mine. The coin is already listed on two small exchanges with no trading volume in general, so you might want to wait for a more serious listing later on before starting to trade it.

Although the project is still new and being actively developed it has generated a lot of attention already, so you might want to check it out in more details if you are looking for something new and interesting to mine. Some good places to trade the SIN coins (formerly SUQA) include Citex, Stex, Crex and TXbit.
