The Tellor (TRB) crypto project has officially entered into the FPGA domain with HashAltcoin just announcing the release of support for their Blackminer F1 FPGA line of miners. Prior to that you could mine Tellor with your GPUs using a miner like the latest NBMiner, though with a GTX 1080 Ti GPU doing just about 750 MH/s now it is becoming rather pointless with a single Blackminer F1+ FPGA doing about 10 times that.

HashAltcoin Blackminer F1 FPGAs Expected TRB Hashrate:
– Blackminer F1 Hashrate: 4.7 GH/s
– Blackminer F1+ Hashrate: 7.05 GH/s
– Blackminer F1u Hashrate: 9.4 GH/s

According to Hash Altcoin’s profitability calculator the newly released Tellor (TRB) mining support is not that profitable at the moment and certainly not the most profitable to mine unless you have a Blackminer F1 Ultra miner. For the other two older products it is in the top 3, so if you you have any of these FPGAs miners physically or hosted you should keep an eye on the new Tellor (TRB) support and its profitability as it may grow or not with FPGAs replacing the GPU miners.

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+.
