Description
Another Bitcoin Miner from Canaan manufacturer is the Canaan
AvalonMiner 821. Bitcoin is the top coin, and thus, the miner uses
the SHA-256 algorithm. It comes with a maximum hash rate of 11.5
Th/s and power consumption of 1200W.
The miner is also known as the Avalon A8 and packs a punch when it
comes to performance. Released in February 2018, this is one of
Canaan’s improved Bitcoin miners. Miners can mine a total of 41
coins with this unit.
Details, Factors, and Spotlight of the Canaan AvalonMiner 821
DigiByte and Zpool are the most profitable coins, followed closely
by Mining Rig rentals and Zergpool. Unfortunately, the miner is not
ASIC supported, which means no one can manage the unit elsewhere.
The disadvantage of this is that you can’t continue with your other
chores when mining. ASIC supported miners give miners the ability
to monitor the performance while away.
Other highly profitable coins to mine with this unit include Acoin,
Joulecoin, Peercoin, and more. There are reliable mining pools that
are associated with this unit. These pools include AntPool,
NiceHash, SlushPool, and others.
If you are interested in buying the miner, check with the
manufacturer. You can also order it from selected stores and
vendors.
Algorithm of the Avalon A8
The SHA-256 algorithm is the algorithm behind Bitcoin mining.
Thanks to having no vulnerabilities, the algorithm is secure. There
have been no break-ins, unlike other hashing algorithms.
Since SHA-256 is not an encryption function, no one can decrypt it.
With this algorithm, you get 4 chipboards under the miner. It uses
a chip count of 104, and the chip’s name is A3210.
The chip’s size is larger than most coming in at 16nm.
A single AUC3 may connect up to five Avalon minors.
First, you’ll need to make sure your Avalon controller is set up
with the correct firmware and is configured to mind to the correct
pool. Then plug in your micro USB power adaptor and ethernet cable.
Once completed, connect your AUC3 to your minor using the AUC3
cable and then to the controller using the micro USB to USB cable.
In order to run more than one minor on a single AUC3, you’ll need
an additional AUC3 cable to connect the main minor to the
additional minor, then another AUC3 cable from that linked minor to
the next and so on and so forth. The AUC3 will blink one in four
colors, each with its own meaning. Now connect eight of the six pin
plugs from your power supply unit to your minor. Remember, your
power supply unit must have a max wattage output, meeting or
exceeding the minor’s power consumption wattage in order for the
minor to run. The power supply unit typically does not come with a
power cord. Once the power supply unit is plugged in, the startup
procedure begins. This may take five to 10 minutes, depending on
the minor and setup.
Here you can see what the 93% efficient power supply at 117.9
volts. It is consuming 1,238 watts.
The hashing rate can be monitored here on the Avalon controller’s
dashboard, which, with this set up is hashing at a steady rate of
11.44 terahashes per second, which is almost half a terahash higher
than the advertised rate.
