New Improved HashAltcoin Blackminer F1-Ultra FPGA Miner

7, Dec 2019

There are a lot of FPGA mining solutions out there, but arguably the most user-friendly one seems to be the Blackminer F1 series by Hash Altcoin. The company has just announced it is going to retire their retirement of the Blackminer F1 and F1+ devices as they have been sold out and there are no plans to manufacture them in the near future, but there will be a new device to take their place. The new Blackminer F1-Ultra FPGA miner is up for pre-order at a regular price of $2100 USD ($2100 USD if you use your invite code + $200 USD coupons), or $2000 USD if you want to support us and use our invitation code ZLOZLA. The shipping of the new HashAltcoin Blackminer F1-Ultra FPGA miners should start on 25th December and the same goes for the availability of hosted miners.

The new Blackminer F1-Ultra should contain 2 hashboards with improved hardware design and product structure over Blackminer’s previous product series. The upgraded core chips should improve the performance by more than 20% according to the manufacturer and the supported algorithms should also be optimized, and the optimization rate of different algorithms can reach 5% to 15%.

HashAltcoin Blackminer F1-Ultra Expected Hashrate:
– Veriblock (VBK) – 15.5 GH/s – 700 W
– VerusHash (VRSC ) – 372 MH/s – 494 W
– Nervos (CKB) – 26.5 GH/s – 1137 W
– DigiByte (Odocrypt) – 5.75 GH/s – 1157 W

It is interesting to note that the numbers above listed by the manufacturer are a bit weird and kind of contradict to what Hash Altcoin claims in terms of performance improvements compared to the specs listed on their website for the F1+ miners. The F1-Ultra hashrates for VBK are lower with similar power usage and for VRSC the hashrate is also lower with higher power usage compared to F1+ for CKB and DGB the hashrates are higher, but with higher power usage as well… maybe these are not the final specs and further improvements could be achieved as we are currently not impressed. Also the fact that the number of supported algorithm at this point is very limited, though the ones quoted by the manufacturer are among the most profitable to mine at the moment, lacking support for some others may lead to missed opportunities at times… compared to the much wider number of supported algos by the F1+.

Mining Nervos (CKB) is Quickly Moving Away From GPUs to FPGA Miners

19, Nov 2019

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.
