The firmware is stolen from Bitmain and slightly modified to have Blackminer name and images... highly suspect

Does it have to be an Antminer? There are other choices that will give you better return and be less loud.

It's not an ASIC, it's FPGA.

They're going for around $11k now, and they're more than twice as efficient. Given expensive power, the SP is a better choice. If your power is cheap or free, D5 is a better choice. Regardless of either, I don't consider mining X11 to be a good idea AT ALL. DASH is indeed pumped by Bitmain and has little real backing.


You are wrong. Bitmain did not even ship their G2 miner (GPU based) until December 2017, and it only did 220MH/s at 5.5 J/MH. The E3 shipped in July 2018, and it only does 190 MH/s at 4 J/MH, a tiny improvement. Considering the DRAM requirements and shortage of available parts during the late 2017 - early 2018 timeframe, I don't suspect that other manufactuers (e.g. Innosilicon) had working parts during this time either.

Anyway, if there were any groups doing secret mining, they haven't released their miners. Inno and Bitmain are the only groups that have released their parts publicly, and only Innosilicon's are a marked improvement over GPUs (1.8 J/MH, 485 MH/s).

I don't have any Z9 minis or interest in this firmware, but I appreciate reading the back and forth here, wish more developers in this sphere had your good attitudes

The BM chips are connected via internal serial links, so you should be able to install any new variant of OpenWRT and re-use the original cgminer binaries from the stock firmware.

Wrong. ASICs can be built to be partially generic or support multiple algorithms. This was proven very early, SFARDS had a BTC/LTC chip in 2013. Every single ASIC Baikal has released is multiple algorithm, even if it is just variants like CN and CN-lite on the Giant N.


Again, wrong. Zig (aka PinIdea) uses a FPGA controller on the board to manage each hash card, but the actual hashing chips are ASIC. There is a low power Altera Cyclone FPGA used as a controller, not strong enough to do hashing.


You are manufacturing 28nm chips however, the costs involved are definitely lower than what is happening at Bitmain. If your statement is true, there is a major disconnect from your public products and the truth.


I have been making this statement repeatedly already - THIS IS ALREADY WHAT IS HAPPENING. PinIdea was previously a manufacturer of X11 miners and released a Cryptonight classic miner in late March. Shortly after the drama about the Cryptonight algorithm switch, PinIdea's website vanished and all mention of their products dropped off the net. ZigMiner is clearly a rebranding of the PinIdea company despite their denials:

• The units are physically identical to PinIdea. The PinIdea's Raspberry Pi was custom fabbed and had a golden PinIdea logo on it, I would be interested to see if that is still present on the ZigMiner controller board.
• The specifications for the ZigMiner R1 is identical to the PinIdea RR-200/210, and not similar to any other Cryptonight miner on the market.
• The specifications for the ZigMiner D1 is identical to the power draw per-chip for the PinIdea DR 100 Pro.
• The firmware on the ZigMiner Z1/Z1+ has a few files that explicitly mention PinIdea, and the general structure of the firmware is identical to the firmware on the RR-200/210. The RR-210 used the same FPGA_download.sh file in /root to upload the bitstreams to the FPGA controller.

Send a test unit to @philipma1957  at no cost, for testing. He is a trusted user of this forum and reviews many miners.

https://www.zigminer.com/ is the official website.

This is normal, and is not the responsibility of the manufacturer to resolve. You purchased this device with the understanding that it was not exclusive to you and that network hashrate increasing means profit decreasing. If you were not aware of this, then that is your own fault. The situation is the same and always has been the same, since the earliest days of mining - additional miners will share the profits, they do not create extra profits out of thin air.

You would need to load the firmware onto the card in full, it is larger than 60 MB but Windows won't show the partitions on the card. Baikal has instructions for upgrading the firmware on their site which you can reference.

You have like a dozen miners, what amount could you possibly be asking for ?

Literally how every miner ever has worked. Are you new here?

5.4 mBTC/day per miner is pretty good, considering the state of the market.

Vosk, what are the symptoms of the crash - does the miner lock up entirely, or does it just stop hashing (either on one board or all) ?

Profits are already tanking with only Obelisks on the network.

Guy,

are the algorithms on-chip implemented in a way where they can be decoupled or reordered? This would be similar to how Baikal implemented their X11 chips and is what allows them to also support algorithms such as Quark, Qubit, Myr-Groestl, plain Groestl etc. If the SPx36 is capable of doing this, it would be a complete game-changer for many, many different coins currently at the mercy of Baikal alone. I understand if you don't want to answer this question publicly, of course - this massive leap in hashrate would destroy many of these small coins.

I would just mine Qubit with it, consistently the best option.

Disabling SSH will not prevent vendors from doing this... they can just modify the firmware on the USB key. There is no effective method to prevent this, really...
