Principal Fired For Using School's Computer Room To Mine Cryptocurrency (bbc.com)

"A Chinese headmaster has been fired after a secret stack of crypto-currency mining machines was found connected to his school's electricity supply," writes the BBC. An anonymous reader quotes their report: Teachers at the school in Hunan became suspicious of a whirring noise that continued day and night, local media report. This led to the discovery of the machines, which were mining the crypto-currency Ethereum. They racked up an electricity bill of 14,700 yuan [£1,600, or about $2,100]...

The headmaster had originally spent 10,000 yuan on a single machine for use at home, but allegedly decided to move it to the school after he saw how much electricity it consumed... A total of eight mining machines were installed in the Hunan school's computer room between summer 2017 and summer 2018... The deputy headmaster also became involved in the scheme and allegedly acquired a ninth machine for himself in January, which was also installed at the school. The computer network in the building became overloaded as a result of the mining activity, according to reports, and this "interfered" with teaching.

All the money earned through the mining operation has now been claimed by the local official responsible for "discipline inspection."

      No it can't. Its a mathematical nonsense to suggest it can be.

      Any useage of power is always a fairly simple equasion of X: work + Y: entropy. You can try and reclaim as much of y was possible and thats fine, but its the x thats the problem here. When your cryptomining the y part doesn't distinguish between "A: Did I find the code" and " B: Didn't find the code" for a more accurate A + B + Y, and the whole key to cryptocurrencies being secure and fair is on B being as high as possibly so the best you could hope for as a SYSTEM is a low A , a low Y and a high B. But for the purpose of energy conservation B is as bad as Y, because ultimately its competing with a system that has no B at all.

      And heres the crunch: Nobody seems to have a use-case for bitcoin that makes having that "B" factor in there at all make sense. Its a gigantic amount of wasted energy for no gain that simply doesn't have to exist. We're a decade or so into cryptocurrency and we're still looking for its use-case (Its not anonymous, its hopelessly vunerable to fraud, it behaves in a manner that is economically absurd for a currency, its expensive as a unit of trade and its unstable as a speculative investment).

      Its a mathematically inescapable waste of energy in an era where wasting energy is the worst thing we could be doing as a species. Lets shelf this idea until we've unleashed Fusion , or big space-mirror power or something that means "B" doesn't matter anymore

      No it can't. Its a mathematical nonsense to suggest it can be.

      It's not mathematical nonsense.... All the energy consumed by a Cryptominer is dissipated as heat.

      That said, miners take more energy to produce the silicon and are more expensive than a simple coil.

      Also, in many places... other sources of fuel for heat such as heating oil or natural gas are more cost efficient, so there's that....

      But its not very unethical to call a miner a "networked space heater" --- if its been programmed to work as one; because thats essentially what it is;
      on the other hand concealing the nature of its network usage might be unethical, particularly if it utilizes significant bandwidth.

      Otherwise you could just distribute black box units to your co-workers to run as space heaters throughout the winter ---- Make an iPhone/Android app required to be used to turn on the heater and adjust its settings (network connectivity required to enable), and Alexa or Google Home integration for reading the current temperature, and i'm sure they'd appreciate that.

      The energy consumed by logic circuits is erasing state, and ALL that energy is released as simple waste heat.
      The ability to "reclaim" the energy is not necessary, because the whole purpose of a space heater is ALL the heat is waste heat and
      to release waste heat in order to heat the room. .... There is no fuel or energy loss in a chemical process such as in fuel combustion heaters. That is why radiant electric space heaters are said to be 100% efficient -- miners are in just the same category.

      The only thing better is a heat pump which can be 300% efficient by bringing in 10kBTU of heat from a source using 1kW of electricity;
      although the efficiency decreases as the heat source gets colder.

    Cryptocurrency != wasting electricity. That's a problem with -some- current coins, specifically Bitcoin.

    I'd be happy to switch cash payments to some electronic equivalent, provided it comes with the same attributes as cash. Afaik such an e-coin doesn't exist yet (Bitcoin in its current form isn't it, that's for sure!). But I suspect that's only a matter of time. And when such an e-coin gains traction, traditional banks (and perhaps even governments) will be in trouble for sure.

    The current crypto-currency craziness is kind of a Wild West shootout, where it's being figured out what works & what doesn't. Once that's fleshed out, the railroads will come, new towns will be built & bank robbery will be a rare occurrence. Figurative speaking, of course...
