Obelisk has started with SIA and Decred ASIC miners with a bit of controversy back in 2017, and now they are apparently planning to extend their offers with new GRIN ASIC miners for later this year as it seems this is the new hot thing for ASIC miners – the GRIN’s Cuckatoo31 algorithm. The company has announced the start of a pre-sale for their new GRN1 miner that comes in three form factors: a traditional form factor (GRN1), compact form factor (GRN1 Mini), and an immersion form factor (GRN1 Immersion). The Obelisk GRN1 miners are designed for Grin’s Cuckatoo31+ hashing algorithm and they will NOT Work on the existing Cuckaroo29+ or future Cuckatoo32+ algorithm implementations.

Obelisk will be manufacturing a maximum of 2,500 GRN1 units (60,000 chips), available in first-come, first-serve fashion. GRN1 Mini units count as 1/6th, and GRN1 Immersion units count as 2. Only 2,000 GRN1 units are available in this sale. The remaining 500 will be sold by Obelisk at market-price when production is completed in October. This sale will close on May 3, 2019. Obelisk expects to ship orders in October 2019. Below you can find the estimated specifications and prices for the upcoming ASIC miners… as you can see the prices are pretty steep, though the hashrate they deliver currently is quite profitable, but who knows what will happen by the time you get the hardware in your hands. As usual with any pre-orders and specifications announced prior to actual products in existence you should be extra careful as very often the final specs are not the same as initially announced, meaning that you could easily get lower hashrate and/or higher power consumption. Though there are cases that the final specs may be better then initially announced as well, you should still proceed with caution and also check other alternatives such as the upcoming GRIN ASIC miner from Innosilicon.

Blackminer F1 Mini is a new single-chip FPGA miner from Hashaltcoin that supports the same large number of crypto algorithms as their larger multi-chip Blackmienr F1 and Blackminer F1+ FPGA mining devices. The new Blackminer F1 Mini FPGA miner is a great entry level device that comes with a price of $179 USD and is available for pre-order with delivery time set for May 5, 2019. The the first batch of the F1 mini is only 300 units and it comes with no power supply or heatsink in order to reduce the shipping cost, these you need to provide yourself. You need an ATX power supply (6-pin PCI-E), DC 12V 6A or 12V 8A power supply (50W typical power usage) as well as a pretty standard cooler for Intel LGA115X CPU that should be compatible with the design. We have not tested any hardware from Hashaltcoin yet, though the F1 mini does sound like a nice and affordable FPGA miner to try and experiment with before going for any of their larger products…

You can use our invitation code ZLOZLA when ordering a miner from HashAltcoin, should you decide to, in order to get a $100 USD coupon code for your next order (can be used for electricity costs should you decide to get your miner hosted). The invitation code will work for orders of other Blackminer devices as well, regardless if you choose to have the device shipped to you or to have it hosted by HashAltcoin.

Canaan Creative has announced heir second generation 7nm AvalonMiner ASIC – the A10 that should be capable of delivering 31 THS SHA256 hashrate with 1736W of power usage (56 W/THS energy efficiency). The 30 THS efficiency with 1700 Watts of power usage was supposed to be delivered last year with the announcement of the first 7nm ASIC miner – the Canaan Avalon A9, however the first generation 7nm hardware was not able to deliver what was promised. Not to mention it came at a bad time for the mining and crypto in general – a declining profit and the whole crypto market going down, so the demand for the new devices was really low. Instead of 30 THS, the AvalonMiner A921 was only capable of delivering 20 THS at 1700W of power usage, so the new 2nd gen A10 devices should finally be able to deliver that level of power efficiency. No word yet on pricing and exact availability dates, the official website still does not list the new devices and Canaan is talking about March availability and they just made the announcement at the end of the month, so we should wait a bit more for additional details…
