The latest TT-Miner 3.1.0 Beta 3 comes with added support for the Eaglesong algorithm used by the Nervos (CKB) making this yet another option for a GPU miner for Eaglesong. This update also removes support for the Myriad-Groestl and the Teo version of Ethash (TEO), brings some improvements for the MTP algorithm on RTX GPUs and some small improvements for all ProgPoW variants (ProgPoW, ProgPoWZ and ProgPoW092). 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.
As far as performance for EagleSong is concerned, we are seeing slightly slower performance with TT-Miner compared to the latest NBMiner and GMiner (100+ MH/s slower on GTX 1080 Ti), so definetly needs some more optimizations to ctch up to the fastest Nvidia GPU miners. Is it worth the effort however is entirely different thing as there is information about FPGA support available for the EagleSong algorithm the bitstreams and miners available for Alveo U200 and Xilinx VCU1525 FPGAs, though with the current performance GPU mining on high-end GPUs might still be viable for a while.
TT-Miner supports ProgPOW, Ethash, UBQhash, MTP, Lyra2REv3, Epic and EagleSong 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.
