BitMain has released their first X11 ASIC miner for DASH and the initial batch was sold out in no time. It is no wonder as the specifications of the device claim 15 GHS X11 hashrate for 1200W of power usage, essentially killing all other competition currently on the market offering X11 ASIC miners. The price of the BitMain Antminer D3 ASIC is $2699 USD (1.12020985 BTC or 59.30564711 LTC) at the moment, so pretty attractive for the performance you get even with no power supply included in the price. Shipping is supposed to start around 15-25 September according to the latest update from Bitmain. There is not much information or details available as the launch of the new ASIC miner from BitMain was pretty surprising. They were so in a hurry that even the photo of the new miner on the official website is actually that of an L3+…

Specifications of the Antminer D3:
– Hash rate: 15 GH/s X11 (Variation of ±5% is expected)
– Power consumption: 1200W (at the wall, with Bitmain’s APW3 PSU, 93% efficiency, 25°C ambient temp).
– Dimensions of the miner: 320x130x190 mm

After the recent controversy surrounding BitMain and the alleged use of AsicBoost here comes another scandal for the popular ASIC manufacturer. It seems that the company has introduced a backdoor into the firmware of their Bitcoin mining hardware Antminer that allows it to stop miners remotely. Not that they are doing it or will do it at some point, but the ability to do so and control a very large portion of the global mining hashrate is not something that users want. The backdoor is now publicly called and it seems that all recent S9 hardware is affected, and L3, T9 and R4 series hardware are likely to be affected as well.

What is the Antbleed Backdoor:
The firmware checks-in with a central service randomly every 1 to 11 minutes. Each check-in transmits the Antminer serial number, MAC address and IP address. Bitmain can use this check-in data to cross check against customer sales and delivery records making it personally identifiable. The remote service can then return “false” which will stop the miner from mining.

The crypto ASIC miner manufacturer BitMain has just announced a new product, this time not a high-powered new miner, but a low power WiFi router with a built-in Scrypt mining functionality. The new AntRouter R1-LTC is very similar to the already available Bitcoin oriented product AntRouter R1, but instead of an ASIC chip capable of mining BTC it contains one that is designed for mining Litecoin instead. The mining functionality is powered by the company’s BM1485 ASIC chip allowing you to mine any Scrypt-based crypto coin and not only just LTC. Of course the single Scrypt ASIC chip inside the router is not going to make you rich overnight as it mines with a hashrate of just 1.29 MHS, but still it is a nice and interesting idea for a multiple functionalities built inside a single portable device. There is no price announced yet, but the sales of the device should start tomorrow 28th of April and we are going to see the price then, though you should expect that it will be very similar to the one of the R1 BTC model that is being sold for $39 USD. Unlike the BTC WiFi router that is only for solo mining BTC, the LTC version should be able to be used for mining with just about any Scrypt pool according to BitMain, so it will be a bit more flexible and usable solution.
