That's fine. I do not own or intend to own a Z9, so it doesn't bother me. I was just curious.

People always want something for nothing. May I ask how you accomplished enforcing one image per z9? did you add a remote service for disabling the miner if an image is used on more than one mac?

Efudd - Do you know if the Z9 has the same micro on the hash board as the z9 mini? Does it use the same 4(6) phase VRM? Would you be willing to give up some of that data So I don't have to go through the same disassembly process (I was about to do this then I saw your post)?
( the 2/3 batch z9 minis are current-limiting the hash boards)

It happens because a new idiot is born every minute of every day.

The block reward is 12.5, and 10 goes to miners. This stuff isn't new.

More specifically, 10% of the coin supply is paid out to the zcash electric coin company as a bounty for ongoing development. it is not a premine like many. each block 20% of the mining reward goes to hard-coded addresses that they control. This continues for the first 4 years of mining.  It's been in the code forever, it's been on their blogs since launch. If you didn't know and you were mining it, it's sorta your own fault.

Interestingly... the zencash/horizen team have re-introduced the same thing back into their code. Some of the block rewards go to miners, some to secure/super nodes, and some to their dev fund. People seem to not complain about that one. They keep making their share bigger too.

Just ssh into it and change the miner config

Part of buying a chinese asic is the wait, worry, and dealing with international shipping/customs. It's useful conversation

I was charged $42 like the other user. And that was just custom fees and service fees, no tariff.

My DHL tracking states:

Further Detail:
Shipment has been given a release by Customs.

Next Step:
Unless there is an adhoc exam or a stop by another regulatory authority the shipment will proceed to delivery

No mention of customs fee due yet. This was customs at CVG international airport. ERLANGER, KY - CINCINNATI - USA

It's still a fake until he proves it is submitting solutions from the machine. Did you not actually watch the video?

Guys it's pretty fast to just test it. If you won't, I will when I get home.
Some fan designs work better this way.

24hours is a short period for a pool with less that 5% of nethash

Guys. Stop dealing with those unreliable pools. Just run on luckpool.net or luckpool.org. Solid, zero problems pool. I've used them for a year now on zen.

If I were you (in texas) I'd set them to all turn down to 50% usage for the 8 peak heat hours, or 0% for the peak 4 hours. Electronics do not want to run that hot. Cap life is inverse to operating temp. Silicon transistor MMTF is log inverse to operating temp

If I were launching a new coin and I wanted instant hashpower, I'd choose the current equihash params and do something like komodo with cross chain proving to bitcoin. Easy to get people interested in mining your coin if they cant mine anything else lol

The Z9 and A9 only represented a 10x-20x improvement in power efficiency. That's less damaging than 100x.

I think the lesson here is don't make generalizations.

Capacitors of some types are very vulnerable to damage from surge currents ie solid tantalum and aluminum electrolytics. Power on events can, in poorly designed systems, result in large surge currents.

I'd imagine it is twice the hash chips, same board design mirrored, and run at 50% higher clock.

FYI, all of the variation you see is due to how equihash solutions are generated. The number of rounds of equihash per second is the same and only depends on the clock rate of this device. The statistical average is two solutions per round of equihash, but its can be more and less.
