The latest TT-Miner 3.2.0 Beta 8 comes with added support for the Kadena (Blake2S) algorithms algorithm used by the Kadena (KDA) project that was recently launched and started with CPU and solo mining initially. Now there is a pool available for mining KDA – IceMining and you can use the latest TT-Miner Beta release to GPU mine Kadena on Nvidia GPUs, there is a miner available for the AMD GPU owners as well – SRBMiner-MULTI 0.1.8. Have in mind that since KDA uses Blake2S is is apparently also already available for FPGA miners such as BittWare CVP-13 that is powered by Xilinx VU13P FPGA, also available for Xilinx VU9P (BCU1525 and BTU9P) FPGAs with slower hashrate and others may be coming out with support soon as well, so GPU mining might not be viable for long.

Do note that if you get a missing DLL error when trying to run the miner on Windows you may need to download the latest Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019.

TT-Miner supports ProgPOW, Ethash, UBQhash, MTP, Lyra2REv3, Epic, EagleSong and Kadena (Blake2S) algorithms on Nvidia GPUs and is available for Windows and Linux as pre-compiled binaries, a closed source miner with 1% developer fee for all of the supported algorithms.

A new website (registered just yesterday) has appeared for a company called ZXMiner claiming to be selling the first Nervos (CKB) ASIC miner for the Eaglesong algorithm. The website is in Chinese and the price for the ZX1 ASIC miner supposedly delivering 820 GH/s with 1100 Watts of power usage is 18000 CNY (Chinese Yuan) which is roughly $2560 USD (payments taken only in Bitcoin). According to the website the estimated shipping date is January 2020, meaning that they should have developed the hardware before the mainnet launch of Nervos that happened recently. We would advice to be extra careful with this as it may be a scam, even though it is apparently not targeted at non Chinese crypto users as the website does not have an English version.

Soon after the mainnet launch there have been news of FPGAs supporting the Eaglesong algorithm that the project uses and now there is information about a possible ASIC miner incoming, though you should treat that with extra caution. The ZXMiner ZX1 photo on the website is actually an edited photo of the MicroBT Whatsminer M3 ASIC miner with zxminer logo put on top of the device and doing that is never a good sign and definitely not a way to earn trust. We also don’t like this line of text “No refund or return after payment, regardless of whether it is shipped or not” as translated by Google Translate, so don’t be in a hurry with this ASIC miner!

Just a few days after the official launch of the Nervos (CKB) mainnet and GPU mining the Eaglesong algorithm may alterady become pointless with FPGAs apparently getting support for the algorithm. First was the information about FPGA support available for the EagleSong algorithm with bitstreams and miners available for Alveo U200 and Xilinx VCU1525 FPGAs. Now Hash Altcon has also announced support for Nervos CKB mining on their Blackminer F1 series of FPGAs with the CKB bitstream to be released soon. They state Eaglesong hashrate of 22 GH/S with power usage of 1020 Watts (1.1 GH/S for single GTX 1080 Ti with 200W of power usage), so definitely more efficient than GPUs. This is signaling the end of GPU mining for Nervos (CKB) and a move onto FPGA mining for sure. There was a pick in mining hashrate yesterday when first new of FPGA support broke out, though today it is lower, with Blackminers F1 joining the game in the next few days there will most likely be another spike in hashrate… depending on profitability of course. With the slow difficulty adjustment that Nervos (CKB) currently uses there may still be some more time left for GPU mining, though even at the moment profitability does not seem attractive at all.
