GPU Mining Cortex (CTXC) the AI on Blockchain Project

4, Dec 2019

The Cortex (CTXC) AI on Blockchain crypto project caught our attention recently with the Cortex algorithm getting added in the GMiner 1.80 miner and the recent Binance listing of CTXC. One of the more interesting goals of the project includes implementing AI DApps (Artificial Intelligence Decentralized Applications) on the blockchain, so thinking along the lines of Ethereum with AI and machine learning. The project does seem to have some solid backing, but apparently initially mostly focused on the Asian market and thus not getting a lot of attention outside the continent up until recently. Have in mind that Cortex is just starting to develop and needs more work, even though it has been launched more than a year ago apparently…

As we have mentioned if you are interested in mining Cortex (CTXC), you would probably go for the latest GMiner software, though mind you the developer fee for the Cortex algorithm is pretty high at 5%, unlike the regular 2% for other supported algorithms. There are still just a few mining pools available wit support for CTXC and no wonder the largest one is Russian called Frostypool, though you should easily figure out how to use it. Alternatively you could go for CortexMint or CortexPool. The network is not that big, so apparently not that many users mining currently, though it seems that already half of the total supply of coins is in circulation and there is a lot of trading going on on some of the large Asian exchanges such as OKEx, Bithumb, Huobi etc. where most of the trading volume is.

It is interesting to note that the hashrate reported by the GMiner in G/s is not the same as the hashrate that you see poolside in H/s, so this is creating some confusion among users and is making it harder to actually calculate how much you can earn mining CTXC. It is best to see your poolside hashrate and then do the math and not rely on G/s data from the miner, but here is an estimate on what you can expect to earn from 6x GTX 1080 Ti at the moment – around 50000 BTC satoshi equivalent or about $3.6 USD equivalent per day. Some good crypto exchanges to trade CTXC coins include Bittrex and Binance.

New lolMiner 0.9.2 OpenCL GPU Miner With More Cuckatoo 31 Improvements

3, Dec 2019

The latest update of the AMD OpenCL GPU miner lolMiner 0.9.2 brings some extra performance boost for the GRIN-AT31 (Cuckatoo 31 algorithm) on 8GB and 16GB video cards of up to +5% on AMD Polaris and AMD Vega GPUs and up to +10 on AMD Navi GPUs. The latest version also adds experimental support for GRIN-AT31 and Polaris, Vega and VII using AMD ROCm drivers under Linux. The lolMiner 0.9.2 has added range checks to GRIN-AT31 code for improved stability as well as added function to call external watchdog scripts in case a GPU fails during mining (if the miner detects no action of a GPU for at least a minute it will call the included reboot scripts).

Grin C31 lolMiner 0.9.2 expected hashrates:
– AMD Radeon VII (stock): 1.79 G/s
– AMD Radeon VII (1340/1000/0.825v, 130W): 1.37 G/s
– AMD Vega FE (stock): ~1.3 G/s
– AMD Vega 56 (1220/900/0.825v, 130W): 1.0 G/s
– AMD RX 5700 (Red Dragon, stock): 0.91 G/s
– AMD RX 580 8GB: 0.56 G/s

We remind you that lolMiner is a closed source OpenCL GPU miner available for Windows and Linux as pre-compiled binaries only and that there is a 1% developer fee for using the software for all supported algorithms. The miner should work on Nvidia GPUs with OpenCL, however stability and performance could be far from optimal, so it is best for use with AMD GPUs. For Nvidia GPU miner with support for Cuckatoo 31 you can check out the latest GMiner, NMBiner or some of the other option like BMiner etc.

New lolMiner 0.9 OpenCL GPU Miner With Cuckatoo 31 Performance Boost

20, Nov 2019

The latest update of the AMD OpenCL GPU miner lolMiner 0.9 brings significant performance boost for the Cuckatoo 31 algorithm used by Grin on 8GB AMD cards (+22% on Polaris and up to 30% on Radeon VII) and reduced Grin stale shares. The new version also has the 16GB solver for GRIN-AT31 disabled as it seems that the 8GB solver is faster at the moment in terms of hashrate. Do note that currently AMD Navi support is disabled for the new algorithms and Cuckatoo-31 on ROCm drivers falls back to 4GB kernel.

Expected performance on Cuckatoo-31 (stock settings):
– Sapphire RX 580 Pulse 0.55 g/s
– Radeon Vega 64: 1.2 g/s
– Power Color Radeon VII 1.53 g/s
