Ethereum Plans To Cut Its Absurd Energy Consumption By 99 Percent (ieee.org) 136

An anonymous reader quotes a report from IEEE Spectrum: Ethereum mining consumes a quarter to half of what Bitcoin mining does, but that still means that for most of 2018 it was using roughly as much electricity as Iceland. Indeed, the typical Ethereum transaction gobbles more power than an average U.S. household uses in a day. "That's just a huge waste of resources, even if you don't believe that pollution and carbon dioxide are an issue. There are real consumers -- real people -- whose need for electricity is being displaced by this stuff," says Vitalik Buterin, the 24-year-old Russian-Canadian computer scientist who invented Ethereum when he was just 18.

Buterin plans to finally start undoing his brainchild's energy waste in 2019. This year Buterin, the Ethereum Foundation he cofounded, and the broader open-source movement advancing the cryptocurrency all plan to field-test a long-promised overhaul of Ethereum's code. If these developers are right, by the end of 2019 Ethereum's new code could complete transactions using just 1 percent of the energy consumed today.

Ethereum Plans To Cut Its Absurd Energy Consumption By 99 Percent

  • Is this going to make it easier to mine, or is it only going to help with transactions? I though that the majority of energy was in the process of trying to mine the next coin, not verifying transactions. Would this be akin to saying we are going to cut energy consumption by using lower-resistance power lines?

      You 'mine' a coin by processing a transaction. The person who processes the transaction gets free coins as a reward for doing the mining. For bitcoin, the reward gets smaller and smaller over time, until eventually there will be no new coins mined, and the transaction fees will increase to cover the cost of processing the transaction.
      • by Vanyle ( 5553318 )

        So if there are no transactions available the processors cannot make new coins?

        • That's a good question, I'd have to look at the source code to be sure. You might be able to just do an "empty" transaction (that is, a block with no transactions in it).

          In practice, if that ever happened, a processor could just send some money to themselves to make a transaction.

    Ban all cryptocurrency mining and transactions. Seriously. It is beyond insane that we, the human race, allow this idiocy to continue.

        Less than if all of it would be managed through bitcoin. Several orders of magnitude.

        I'm guessing you didn't click through to this article with graphs related to that very question [digiconomist.net].
        If one believes those graphs, and i see no reason not to,
        here are the number of US Households which could be powered by the current energy consumption of various transaction networks:

        bitcoin: 4.2 million
        ethereum: 1 million
        visa: 0.017 million

        so visa is 1/200th as energy-consumptive than bitcoin. that's two orders of magnitude plus a factor of two.

        that same page reports that a single bitcoin transaction, just one, consumes enough energy to power a US household for 15 days.

        yeah, i think banning should be considered.

        • so visa is 1/200th as energy-consumptive than bitcoin. that's two orders of magnitude plus a factor of two.

          By what metric? In total usage yes, but that ignores utility. Bitcoin processes 1/600th of the transactions every day compared to Visa with their current 1/200th energy consumption.

          Therefore Visa is actually as 1/120000th as energy-consumptive for achieving the same goal, moving money from point A to B.

          It is clear the world will not achieve net zero carbon emissions for energy generation, so reducing consumption should be a great part of the focus. I agree with your sentiment that banning should be consider

    • nonsense. you have a huge misconception.

      the energy taken by cryptocurrency is miniscule. Civilization uses 132,000 TW hours per year, yet Etherium is only using 10 TW hours per year. It doesn't matter. Neither does bitcoin, you believed the nonsense article run here that misunderstood an IEEE article, saying that someday Bitcoin would consume as much as Denmark at (then) rate of growth...even while also saying its energy consumption was like a large city at the time.

        I didn't misconceive a damn thing. Bitcoin uses more energy than Hong Kong, which has over 7 million people. Beyond that, the network is mostly fueled by coal-fired power plants in China so the carbon footprint is massive. Combine that with all the other silly cryptocurrencies and we've got a real problem.

        A quick Google search found many scientific articles about how crypto mining is contributing to climate change at alarming rates, so it looks the person who needs to "get it through your skull" is you.

        Sorry you're butthurt that your crappy investment in crypto isn't paying off, hypocrite.

  • People should learn how much electrical power the world uses before thinking Etherium consumption is anything at all. Hint, it's not, it doesn't matter.

    Or to be exact, it is 0.00007575757 of the global total. Yeah math and relative magnitude are hard, around here.

    99% reduction in energy demand? Doesn't that mean 99% reduction in required workload and thus either a 99% reduction in the core value of the coin or more likely a 10000% factor increase in the number of people who now have an interest in your new super cheap to mine coin?

    • They are switching to proof-of-stake instead of proof-of-work. Instead of using all the compute resources required to calculate a hard problem on every participating machine all the time, your computer gets to sit idle for most of the time. When you and your friends get your turn to process transactions (which is based on how rich you are), you get a portion of the transaction fees.

      This allows Ethereum to be only a couple thousand times more expensive per transaction than Visa, and with a fraction of the fe

      Not really. They are planning on switching from a Proof Of Work algorithm that requires "mining" coins with brute force mathematical computations to a Proof Of Stake algorithm where the largest crypto holders who help with processing network transactions get a cut of the transaction fees.

      The algorithm seems to be much more energy efficient, but tends to favor giving more coins to the few people who already have the most of it. In a way, it tends to work more like fiat currency than gold mining... the rich tend to get richer off the interest, and the rest of us just tend of stagnate where we are.

        you will be able to participate in a proof of stake even with very little ethereum. The goal is to create staking pools, like you have mining pools for POW. If you participate in a pool that behaves correctly you get a reward per validated transaction proportional to your share in the stake pool. Seems fair. OTOH if you participate in a stake pool that misbehaves you lose your stake. This builds a network of trust between stake pools.

          So then shady stake pools pop up that abscond with the entire pot after some period of complacency, just like many dozens of mining pools...

      • Proof Of Stake ... tends to work more like fiat currency than gold mining... the rich tend to get richer off the interest, and the rest of us just tend of stagnate where we are.

        IMHO, a fixed percentage interest is fair. The rich don't get proportionally any richer because everyone's balance increases by the same factor. This is also how Proof of Stake in cryptocurrencies has worked since it was introduced in Peercoin around 2012.

        The problem with Ethereum is that you need a minimum balance in order to gain any interest. The rich will get proportionally richer, for no good reason. This idea is similar to masternodes [iki.fi] used in several coins. Thus cryptocurrencies that were supposed

    • by AmiMoJo ( 196126 )

      Etherium doesn't really rely too much on mining. 70% of the available currency was mined before it even went public. The energy consumption is mostly transaction processing, which is rewarded. The currency part is really just a way to encourage people to dedicate resources to running the distributed scripts that operate on the platform.

      At least that's my understanding of it.

    • The paradox [wikipedia.org] was observed in the coal era. It suggests that when a resource gets to be used more efficiently, that increases demand for it and therefore increases consumption.

      So while Ethereum might produce more efficient code to reduce the per transaction waste, the overall effect of making each transaction so much cheaper could simply be to make transactions more attractive by a greater amount.

  • First the alcoholic needs to sober up, and only then can he or she look for an actual job. Cutting outrageous over-consumption by 99% is a starting point, not a finish line.

    Person 1: You're useless and unreliable.

    Person 2: Oh yeah? Well, I used to be shitfaced all day long.

    Person 1: My bad. I misjudged you. Next drink's on me.

  • I believed that heavy crypto was a requirement to make transaction difficult to forge. Am I wrong? Or do they lower security? Or did they set the bar much too high in the first place so that they can slash 99% without consequence?
    • The "heaviness" of a Proof-of-Work alt-coin like Bitcoin or Etherium (before this change) has nothing to do with the complexity of the cryptography and everything to do with there being enormous competition between miners because of the perceived value of the currency mined.

      In fact, one can characterize modern cryptography as the art of making a complex enough (to be secure) calculation as efficient as possible. And it is, typically, very, very efficient --- or it wouldn't be used.

    The average transaction fee for an ETH transaction is pennies or less. If that transaction is consuming as much electricity as an average household does in a day, then why aren't we powering houses with all this insanely cheap energy the Ethereum users seem so able to find?
