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.

The Nervos project is nearing its CKB v1.0 Mainnet launch called Lina planned for November 16th or in a week from today, though even in the last days of the testnet you are still able to mine CKB coins thanks to the testnet mining competitions being ran. If you take part in any of these mining competitions the testnet tokens mined will be moved to the mainnet when it launches, though there are some specifics things that you may want to read carefully. The Eaglesong algorithm is more GPU intensive and thus works better on more powerful Nvidia GPUs than on what most widely used AMD cards can deliver, though mining is possible on both AMD and Nvidia hardware.

There are a number of miners available with support for the Eaglesong algorithm available, though probably the most interesting for Nvidia miners will be NBMiner 26.0 (AMD is also supported) for the moment as it supports dual mining of ETH and CKB. If using dual mining on GDDR5X GPUs make sure you also have the OhGodAnETHlargementPill running as it will help you maximize both the Ethash and Eaglesong hashrates. For instance on GTX 1080 Ti you may be getting 400 MHS on Eaglesong and 33 MHS for Ethash without the pill, and when you run it the performance should go to something like 500 / 42. Mining only CKB should get you around 1100 MHS as hashrate on the same hardware. The latest GMiner 1.73 has also added support for CKB mining for both AMD and Nvidia and it delivers pretty much the same hashrate on 1080 Ti as the NBMiner, though no dual mining in this release (ETH + CKB dual mining should most likely come in next GMiner release). AMD GPU miners have another option for a miner and it is SRBMiner-MULTI that also supports Eaglesong mining. If you are interested in a pool where you can mine CKB, then you might want to start with f2pool, hashpool or spark pool for a start.
