New BitMain Antminer A3 Blake (2b) ASIC Miner Announced

17, Jan 2018

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.

BitMain Antminer A3 Specifications:
– Product model: A3
– Hash ASIC type: BM1720
– Hashing algorithm: Blake(2b)
– Total quantity of hash chips: 180 chips
– Total quantity of hash boards: 3 boards per miner
– Total hash rate: 815 GHS ±5%
– DC voltage input: 11.60~13.00 V
– DC current input @12V DC: 98.8 A +7%
– DC Power @12V DC input: 1186 W +7%
– 220VAC Power @25℃, 93% conversion efficiency of APW3: 1275 W + 7%
– 220VAC Power efficiency @25℃,93% conversion efficiency of APW3: 1.56 mJ/MH + 7%
– Weight (without package): 4.2 kg
– Operation temperature: 0-40 ℃
– Storage temperature: -40-85 ℃
– Operation humidity: 5%RH – 95%RH, prevent condensation
– Noise: 76 dB
– Networking connection mode: Ethernet Cable
– Power connection mode: All three PCI-E ports are required to power the board. You can use one PSU to power multiple boards, but do not attempt to power one board with two PSUs. We suggest to prevent the control board to be powered up before hash boards be powered up.
– Size (Length*Width*Height, without package): 321mm*125mm*208mm

New 16 THS DragonMint 16T Bitcoin ASIC Miner Coming in 2018

23, Nov 2017

If you think that BitMain has too much control over the Bitcion ASICs out there being one of the main manufacturers on that particular market, then you might be happy to learn that there is a new alternative coming next year. There are of course the Canaan Avalon miners and the Ebit E9 miners already available, though they are also hard to get, just like the Antminers from Bitmain lately. The just announced DragonMint 16T Bitcoin ASIC miner from a new company called Halong Mining is looking very promising. What makes this announcement even more interesting is the fact that one of the Bitcoin Core developers – BtcDrak seems to be directly involved in the development of the miner and with Halong Mining who developed it. According to the initial information the project has been started quite a while ago with a lot of people contributing and with a serious investment in order to be able to bring the much needed competition and innovation to the Bitcoin mining arena. The only possible problem here is that it might still be hard to acquire for some small miners and users willing to get just a single ASIC miner to play around with once it becomes available, especially if demand from large scale mining operations is as high as it is with Bitmain’s products.

The DragonMint 16T is supposedly the world’s most efficient Bitcoin miner, running faster and cooler than any competing miners currently available. It is based on the DM8575 ASIC chips that run at 85 GHS per chip with power efficiency of around 0.075 J/GHS according to the developers. If you are wondering what is the catch here, well the new miner is not yet available for sale, it is expected to start shipping in March 2018 or in about 4 months from now. You can however already pre-order the device with a minimum order quantity and a regular price tag of $1595 USD (with first day promo at $1350 USD per device). That price does not include a power supply, just the miner, but you can also add a 1600W PSU for $125 USD ($115 USD on promo), though again this is a pre-order. As with all other pre-orders and promises for a new product that is to start shipping in the future it is advice to proceed with caution, especially in cases such as this one where it is from a newcomer in the crypto space (new company)!

DragonMint 16T Specifications:
– ASIC Type: SHA256
– Hash power: 16 THS
– Network: Ethernet port
– Miner power consumption: 1205 W ±6%
– Chip efficiency: 0.075 J/GHS ±6%
– Fans: dual fan variable 6000rpm (100W)
– Power Supply: Not included (1600W recommended)

Only BCC Payment Method Accepted for the Latest Batch of Antminer S9

1, Oct 2017

Something interesting and not so nice regarding Bitmain and their latest batch of Antminer S9 ASIC miners, it seems that although the company is listing prices in USD, BTC, BCC and LTC on their website it will only accept payment in BCC (Bitcoin Cash) for the batch of miners shipping November 21-30. As a maker and seller of these devices Bitmain of course has the right to sell them any way they want and accept the payment in the form they choose, but this way of essentially “forcing miners” to buy BCC to pay for the hardware (in case they do not have it) is probably not very “politically correct”. It is understandable that they want to support BCC, but is this the right way to do it or it will fire back with users going to alternative options for ASIC miners (not that there are many available unfortunately)…

The questionable text about BCC payment for the batch is under Payment and is quoted below:

Only BCC payment method is accepted in this batch, please use the exact amount mentioned in your order and complete the payment within one hour. After one hour, the order will expire and your payment may not be detected by the system automatically. If the payment is submitted but the receipt is delayed, we will make your payment “Valid” manually.
