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 curse. 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.
