The demand for Bitcoin mining hardware seems to causing some strange decisions among the ASIC manufacturers and one such is apparently the announcement of the Bitmain Antminer V9. A small 4 THS SHA256 ASIC miner that uses 1 KW of power, so not very efficient, but it comes cheap at just $345 USD. There are already some speculations that this could as well be old hardware renamed and refurbished as a new product to clear up some old mining hardware used by Bitmain in their mining farms in China instead of having to relocate it to a new place. This batch has a MOQ (minimum order quantity) of 5 units and all ordered quantities can only be multiples of 5 (10, 15, 20 units and so on) with the maximum number of units in a single order up to 300. The shipping for all confirmed orders will start after March 1st and payment accepted is only in Bitcoin Cash (BCH) and USD wire transfer.

All in all not a very exciting new announcement of a new ASIC miner from Bitmain, efficiency wise the “new” hardware is disappointing for the performance it offers at the rated power usage. So it seems to be targeted at users looking for cheap hardware that have really cheap or even “free” power, otherwise it just does not seem economically reasonable to buy these miners at the moment.

This came as a bit of unexpected surprise, but it seems that BitMain already has a working ASIC miner for the Blake (2b) mining algorithm (and maybe even for other variants of Blake) and they have announced their plans to start shipping the Antminer A3. The Blake 2b crypto algorithm is currently being used by SiaCoin (SC) and last year there was a pre-order for an official SiaCoin ASIC miner the Obelisk SC1. BitMain’s ASIC miner however seems to be arriving much earlier with similar specifications and price, so anyone that has pre-ordered an Obelisk SC1 might not be that happy. On the other hand people that are interested in getting into mining SiaCoin and missed their chance with the pre-order might order now from BitMain and get the device shipped in 10 days after payment according to the company.

Some of you might remember that back in June Sia has announced their plans to develop a dedicated SiaCoin (SC) ASIC miner called the Obelisk SC1 capable of 300+ GH/S at 500W or less power consumption according to the latest information. Well, it seems that Sia has figured out that since Decred (DCR) uses a very similar algorithm to what SiaCoin (SC) uses (both being variations of Blake) they can also develop the first ASIC miner for Decred as well. The Obelisk DCR1 should be capable of at least 475 GH/s with less than 500W of power usage and both ASIC miners should be available at pretty much the same time.

So now the pre-sale of the first batch of 4000 Obelisk DCR1 ASIC miners for Decred (DCR) is up for pre-sale on the Obelist’s website along the Obelist SC1 ASIC miner pre-sale for SiaCoin (SC). Both pre-sales will run up until November 24th and they are expected to ship on or before June 30th, 2018. Both Obelisk ASIC miners are available for pre-order at a price of $2499 USD and come with a 6 week exclusive mining period and a $250 per-unit coupon for future Obelisk purchases as a bonus. Now, since this is a pre-order for a product that is currently in development we advice you to be extra careful as we’ve seen a fair share of fails in that area and a lot of empty promises. We are not saying anything for the Obelisk, it seems to have a solid team working on the project according to the information available, we are just warning you to be careful as it is a pre-order for a product that is not yet developed and the final device (if/when available) may as well be different in terms of specifications as we’ve seen that happening as well.

If by the second half of next year Sia manages to deliver on their promise with the Obelisk ASIC miners for SiaCoin (SC) and Decred (DCR) they will significantly change the landscape for these two crypto coins. Now it is yet unclear how this will affect things regarding the use of the Sia file hosting services since it is more than just a crypto coin while Decred is more of a traditional crypto coin. The promise of securing the network better with ASICs is not new, the more important question here however is what if a limited number of people hold most of the ASIC’s power in a network… and then it becomes pointless to mine if you do not have access to an ASIC miner and/or cannot afford one.
