Arguing that a coin with a very low energy usage or "efficient", cannot exist

[joehal__]

The post is quite long so this is the tldr:

Despite news media crying that bitcoin is using too much energy, it's impossible to create a new crypto-coin which uses the same mining principles (so no private companies like Ripple or Visa) but at the same time will use 1% of bitcoin power usage. 1% forever, and not just in the beginning when only 50 people are mining.
Because that would mean that magic coin would cost let's say 1 dollar to mine a day but you would be able to sell it with $100, and that's just not possible. From an economic standpoint.


-------------------

I'm surprised that people like Elon Musk and even big bitcoin proponents do not talk about that. Or at least I have not read about anything like this from them, or in the media which constantly compares bitcoin's energy usage with different countries, and how this and that coin uses much less energy.

I also have smart educated friends who argue about the same thing, that there should be a more energy friendly coin, it should use much less power. They are not able to explain to me how that could be, because they are not technical and I should ask people who are technical. I tell them that this is a logic and human nature problem and not a technical one.

I'll not pretend that I know the inner subtle details of bitcoin programing, but I don't have to, since as I said, this is an economical or logical dilemma.

And logic tells us that btc is not inefficient. Of course this and that coin uses less energy, since they also have a much smaller market cap. When people and news articles talk about how bitcoin uses x kilowatt-hour and that other coin uses less, that's meaningless. This term should be always used as a ratio, you can't just throw that term around.
It's like I would say I have two vehicles and one uses 3 liters and the other uses 20 liters. Without mentioning any metric or ratio like using 3 liters of gas per this much distance. And without mentioning that one is a small car and the other is a truck.

What if a new coin would appear and it would cost only 1 dollar per day to mine 100 coins. Great, it uses so little power. So efficient wow great joy, much green.
But the miner will be able to sell those coins somehow with 100 dollars. Everyday.
Success right ? What the news people and maybe Elon Musk is talking about, has been achieved.
Of course this is impossible, because in the next moments everyone and their doge will struggle to buy all the machines they could find to put them to work to mine that magical coin. And the economies of scale and logic tells us that price will soon equalize and lead to a similar ratio as bitcoin or ethereum has today. It will fluctuate - that energy/selling price coin, as it also fluctuate for bitcoin, but it would still be around that same ratio. Maybe a similar ratio with a lot of other assets in the world which are mined or built.
So no longer that "green". Unless this new coin is using power from renewables. Or excess energy which we know sometimes can't be stored and is wasted in the air. Or instead of being wasted, it is captured and used for mining.
 But that has nothing to do with this debate. Any coin can use energy produced from any kind of source.

There's always gonna be this relation between mining cost and profitability. If there's no profit, no one's gonna mine the coin. If there's a lot of profit, many more people will mine until a balance will be reached. A fine balance, sometimes right on the line between profitability and bankruptcy.

-----------------------------------------------
And just to put a crazy or outrageous idea out there… there could be a way for a crypto currency to be environmentally friendly and also maintain the same necessary difficulty of mining, difficulty and balance which is necessary for the whole thing to work.
But it would be probably difficult to build and design. And I'm not sure how tamper proof a system like that would be. Or if it will not be abused or leave room for corruption. It would have to be done in a completely automatic way, without any human hand, just like bitcoin works today.

 Instead of doing increasingly difficult mathematical calculations which serves only to secure btc or make it tamper-proof and as a barrier of entry, and uses a certain amount of energy which also gives value to btc - this system would use the same GH/s of computation, except a variable percent of this "brain" power could be lend somewhat or donated automatically for no profit or certain medical research institutions or institutions doing general purpose research the kind which benefits everyone, as opposed to only a particular group or certain countries. The whole system would have to be built in a way that for those external institutions - they will only see a certain amount of available "CPU" power, while internally for a software and hardware miner that would equal mathematical usage which would serve as the same purpose of securing the bitcoin network with heavy processor usage and calculations.

Another way, perhaps even more difficult or unfeasible would be for this percent of lend power to be used by absolutely anyone, except it would be allocated randomly maybe away across half the world to this and that person/group/or even company. Randomly so a certain miner would not be able to re-use that computational power for his own purpose and generating coins for free.
What would be the benefit of this scenario ? The benefit would be that in this way, it would be maintained the necessary ratio between power usage/ and profit. So you would not be able to generate profits from thin air, as that would never work. But at the same time that energy would not be wasted with meaningless calculations, but used instead for general computing which will be translated or virtualized and used like the old models of mainframes and terminals.

So again, in this scenario miners would still use a lot of energy to mine, the same as before, like spending this x percent of energy to make an extra 5% of profit.
But that energy used for calculation would not be released into the air in the form of heat, but will be sent somewhere else to be used.

--------------------------
Does anyone know how there can be a crypto-coin with the same utility as bitcoin or ethereum, but is designed to be many more times more efficient ?

[BlackHatCoiner]

It doesn't have to do with Bitcoin directly. Yes, Bitcoin is the first mover and thus, most of the miners and these huge mining rigs work on extending its chain. You shouldn't be faulting Bitcoin, but the whole block chain concept. Truth be told, the blockchain technology is inefficient. A distributed ledger that is kept on every node of the network can't be characterized as something efficient, that's the cost of decentralization after all.

I believe that as long as mining with renewable energy sources becomes more widespread (and more profitable), these folks will change their mind, or if they don't, they'll stop pointing out this excuse.

Mining is structured in a way to always be more damaging, if the coin's value increases, until governments put their hand on. For example, if China illegalizes the use of ASICs, it will be environmental friendlier AND network attackers will still be outpaced.

[ranochigo]

Proof of Stake. Ethereum has plans to shift from PoW to PoS but the security of that is actually quite debatable, IMO.

The complexity of PoW attacks lies with your ability to amass sufficient resources to attack the network in the first place. As the current mining climate is dominated by ASICs, there is no use for them after an attack and thus making pretty much all of the ASICs useless as the price is bound to tank after any successful attack. It really doesn't make sense for people to be able to mine by not incurring any real costs and would definitely be weaker than PoW.

Bitcoin having a huge electrical consumption by its nature is not incorrect. However, there are far more activities that incurs more carbon footprint than Bitcoin and provides far less utility as well. If we were to replace all of the financial systems with Bitcoin, the energy consumption could be far lower while providing numerous benefits. Any more efficient algorithms will probably not replace Bitcoin's PoW as it is pretty much impossible for the community to gain consensus on this issue. It is important to note that you're not wasting electricity by mining, you're being compensated and the benefits that arises from mining is the security of billions of dollars of transaction volume each day. The argument weakens as Bitcoin gets more adopted and its utility increases.

Does anyone know how there can be a crypto-coin with the same utility as bitcoin or ethereum, but is designed to be many more times more efficient ?

All Proof of Stake coins created since 2013 have Greater Utility than Bitcoin in ONCHAIN transaction capacity and energy efficiency , as they can be run as an side app on a running PC.

The top contender at the moment is Cardano, which will be smart contract capable in it's next update.
Cardano is #4 on CoinMarketCap and growing as a very fast rate.

But some of the original PoS Only coins were MintCoin, Blackcoin, Elite ,  Zeitcoin, Inflationcoin, BeanCash, & Sprouts.
All of which are still running & working blockchains.

Problem is PoW is inherently flawed to eventually compete in energy consumption with all of mankind,
because the energy consumption of PoW grows geometrically not linearly, so the energy manufacturer never have time to catch up in energy supply production.
While many here like to make comparisons of energy use between PoW  and other industries ,
the fact is all of those other industries grow linearly, so their energy consumption is more sustainable, as their growth rate is much slower, and their drain is more easily spread across multiple power grids. Where as PoW requires geometric growth that outpaces the energy sector ability to meet demand, causing price increases for everyone, and requires massive areas where they draw too much power for a given power grid.
Which is why you see some communities starting to ban PoW mining.

Problem is Bitcoiners see any energy waste issue pointed out to them as a flaw in Bitcoin, and that they refuse to accept.
The energy waste issue is not an attack on bitcoin, because at  any time since 2013, they could have begun the transition to Proof of Stake, and have refused due to some cultist belief that is totally inaccurate.

Advantages to switching Bitcoin to PoS are the following,
increases decentralization , as anyone owning bitcoin will stake and run Full Nodes
in fact, this is the reason bitcoin core dev have limited BTC onchain transaction capacity.
allows for the increase in onchain transaction capacity
Lowers the cost of transaction fees for everyone, since insanly high input costs are no longer required.
Puts the mining/minting back into the hands of the majority not just the rich elite.
Removes the energy waste argument from the Public arena.
Can go to a carbon zero footprint on PoS, something that will never be possible with PoW.

So will bitcoiners eventually see the truth, as have the founders of Ethereum who are already beginning a transition to Proof of Stake.
Or
Will they hold on to the false belief that a flawed PoW system is Bitcoin?

Time will tell.

I'd be curious to know how much pollution and energy consumption all financial institutions and the worldwide money printing machines create. I'm quite sure they're much, much higher than the one that comes from BTC mining, but we cannot pretend that there aren't other systems that are more energy-efficient than Bitcoin's.. although at the expense of other stuff such as security, which is perhaps more important than energy consumption is! Proof-of-Stake is an option but it's in more of a testing ground right now. Bitcoin is more solid than ever before and it's been 13 years since its inception. If PoS works well enough, Bitcoin will move to it. It's not like we want to pollute the air and use as much energy as possible. It's just that we want security as well, not just an eco-friendly environment..

Maybe my post was too long, but I feel like no one replied to or addressed the title:
a crypto-coin with a very low energy usage or "efficient", cannot exist

Not even with proof of stake, unless that proof of stake would make bitcoin or a new coin just slightly more energy efficient.
But I was talking about something like 100 times more energy efficient, or a coin using just 1% of how much bitcoin uses, while having the same market cap. I feel like only that percent would shut media and critics up.

[fiulpro]

I do feel like Bitcoins can itself become energy efficient because it all depends upon how the person is actually doing the Mining. I do think that the person can actually use green resources more, they could have their own energy farm, self sufficient and at the same time it could pay the person much more per week..it would definitely need some prior investment but at the end of the day for the long term it would be much better.

I do think a coin can indeed exist, the energy can be actually changed in the way so as where it's coming from. Plus there are actually countries where it would be more efficient. The solar energy would be much more common.

[20kevin20]

I feel like only that percent would shut media and critics up.

It might, but they'll find something else to complain about. Like mining fees.

The average Joe has no idea about all this stuff mainstream media talks about, so they take their words for granted. The media has this strong advantage that they can manipulate easily, especially these days.

Dude, you really don't understand how energy efficient Proof of Stake is.

Any Proof of Stake coin is Millions of times more energy efficient than Bitcoin PoW.

Charles Hoskinson: Cardano Is 1.6 Million Times More Energy Efficient Than Bitcoin

FYI:
A PoS network could actually use a few solar panels connected to a battery and run a Laptop 24x7 with a zero carbon footprint.

FYI:

But this energy efficiency of converting let's say bitcoin from POW to POS - refers to only transactions ? Or to the mining of coins ?
Because even though transactions would be better (debatable), the mining of coins would cost as much as before, right ? And the power usage would still be similar to before. The btc energy global consumption would not change that much, no ?

And I was mostly arguing and asking if it would be possible to mine a coin with a low price (that's what media seems to want) and sell that coin with 50 000 dollars. Even though you paid a fraction to mine that coin.

All of the waste is in the PoW Mining, which is what includes the transactions.

Their is no mining in Proof of Stake, it is called minting.

Minting produces new coins and includes new transactions, with only the nodes and coins they hold.

So if bitcoin converted to PoS, all ASIC Warehouses would be unnecessary, as they are what is wasting all of the energy.

Converting from PoW to PoS does not affect the # of new coins created unless you change the code.
So the 21 million bitcoin limit would stay untouched and therefore it's value verse fiat would stay at market price.

Media and general populace don't want their local energy prices increased or environment damaged just because of bitcoin refusal to evolve.
That will cause the majority to begin dumping or banning btc as many have dumped/banned other products they consider damaging to the environment. Banned bitcoins won't be worth anything.

FYI:
No one expects bitcoin to convert to PoS overnight, however since ASICS lose value at an insane rate, 1-2 years, before they are paperweights.
BTC could easily modify the code to transition from PoW to a Hybrid PoW/PoS for 2 years, and then transition to Only PoS by the 3rd year.
By the 3rd year energy and carbon footprint issue solved forever.

I understand what you wrote, thank you for the explanations, and I understand how big usage of energy could be perceived as bad, although it could be argued like someone here said, why do Christmas lights and water fountains and many many others get a pass even though they might consume equally as much ?

But that was not my dilemma. As far as I understood from your post, conversion to a POS system would not affect anything, bitcoin would still remain the same, with the benefit that it would be environmentally friendly and media would no longer hate us. Great.
But miners would still "mint" 6.25 bitcoins per block.
How could a miner sell a bitcoin for 50 000 dollars, if he did not pay for a lot of energy to mine that coin ? Since minting the coins would no longer require insane and wasteful amount of energy.
But at the same time there can't be for the miner such a huge return of interest. From almost zero energy cost to selling a coin for let's 50 000.
While with POW, a miner would have to spend maybe 25 000 dollars (with approximation) to get "in his hands" a bitcoin which he could sell for 50k.

IF you believe the miners are what is holding the price up, how do you reconcile with the price swings of just $15k lower in just 2 weeks.

The actual argument for bitcoin price is due to it being scarce of only 21 million coins, conversion to another algorithm does not have to change that.

If you look at the billions spend on warehouses / ASICS / Energy, all of that could be used to buy bitcoin for miniting, and could potentially make bitcoin more expensive verses fiat, as bitcoin itself would replace the energy wasting ASICS, and could cause more to Hodl since holding would earn more bitcoins. In the eyes of many moving to PoS would make bitcoin more valuable not less.

FYI:
The reason Christmas lights are not an energy problem , is because of distribution and efficiently evolution.
If we took all of the old incandescent Christmas lights in the world and placed them all in a few warehouse,
Additional Cooling would now be required, Coal Plants would have to make up the additional energy required and
they would also overload the energy grid of that region driving up the energy cost$ for everyone in that region.
Christmas lights used to be incandescent and have evolved to super energy efficient LEDs.
So Christmas Lights have evolved to be more energy efficient ,
why does anyone think bitcoin gets a pass on evolving to be more energy efficient.

There's another way you could mint or mine coins without investing money in energy. Being Ripple, or a private company generating 1 billion coins in a night. You bought 500 dollars worth of energy and sold those billion coins with much much more, but that's private company and you can say you pay for that brand, or they are scamy, or who knows what special sauce hides there. Plus they are a company, and it's not like every individual on earth can replicate that easily.

But with bitcoin everyone can start minting or mining coins, and if the cost would be very cheap, everyone would enter and become millionaires. And when everyone is a millionaire, no one is, to quote The Incredibles

But you are saying, with POS you don't pay for energy, so the planet is saved, but you pay instead in holding coins, or a stake.
So it's still a kind of investment required from the miners/minters, just not an investment in ASICS and power.

Do you know if the ratio between investing and profit is similar for a miner involved in a POS operation ? I mean similar to the POW coins.

I don't have any numbers on that , but IMO, market forces and number of coins will cause a variance between coins price verses fiat.
Cardano was only like .10 cents last November, and now is over $2 bucks per coin, so profit is there.
It is sitting at #4 on CMK, so the era of Proof of Stake only coins is beginning.

One main advantage, is where as PoW miners do go bankrupt, no one will go bankrupt from just running a PC.
Input costs of buying new coins can be more variable, than the monthly energy costs required by the electric utilities.

[stompix]

What if a new coin would appear and it would cost only 1 dollar per day to mine 100 coins. Great, it uses so little power. So efficient wow great joy, much green.

Of course this is impossible, because in the next moments everyone and their doge will struggle to buy all the machines they could find to put them to work to mine that magical coin

All PoW coins "suffer" from this, dogecoin consumes less energy just because the reward is smaller, not because it has after blocks or bigger blocks, it's a simple thing of how much miners earn. No PoW coin will ever be able to achieve higher security without an increase in reward and in power consumption.
Just look at the attack on BSV, so yeah, there is no point in arguing one PoW coin is less power-hungry than the other.

There's always gonna be this relation between mining cost and profitability. If there's no profit, no one's gonna mine the coin. If there's a lot of profit, many more people will mine until a balance will be reached. A fine balance, sometimes right on the line between profitability and bankruptcy.
-----------------------------------------------
And just to put a crazy or outrageous idea out there… there could be a way for a crypto currency to be environmentally friendly and also maintain the same necessary difficulty of mining, difficulty and balance which is necessary for the whole thing to work.

I think that the environmentally friendly thing is just as stupid as treating pigs well before your slaughter them and thinking you're a good person, a way of lying to yourself you're making things better by not actually doing anything and not changing your lifestyle at all. Let's be honest on this, I doubt more than 5% of the people who are thinking of buying an electric car with efficient light bulbs are doing so because they want to save the planet and not because of government subsidies, the fear of not being allowed to drive their car in city centers or taxes.

As for the design of a coin, there could actually be a solution. Not bulletproof but still might be a way to solve the consumption a bit.

A miner has two things to worry about, running costs which are mainly energy consumed by the miner, and cooling and getting his investment back.
So the only way of determining a miner to consume less energy would be to make him get his investment back far slower limiting the amount of gear that can be thrown at a coin. How could you do this? Finding an algorithm that is fitting a normal computer as much as possible, making it impossible for an ASIC miner to be cheaper and highly more efficient than a normal desktop. Of course, it will not work completely killing ASICs but it will prevent a bit of the mining rush we're seeing now.
It will also help decentralization as home miners might be able to compete with their computer running a miner in the background and basically not experiencing extra costs while mining farms would still have to think of ROI and power usage.

Of course, you would still have to deal with botnets, huge data centers that might use their spare capacity to mine it, and so on, that's why we don't have such an algorithm yet.
The other way around would be to go the Monero way and update it when the dev teams want to, but that things are a no-go from my point of view because of security, you might end with a drop so huge in hashrate and one flaw might allow a single miner who has spotted it to execute a 51% attack.

There was a time when I used to think that PoS was superior to PoW. But the more I studied about these algorithms, I came to know that PoS is a less secure system, where decentralization can be under threat. And you are right in saying that if PoS was actually superior, then some of these coins might have already overtaken Bitcoin in terms of usage and market cap. PoW may be more energy consuming, but it makes sure that Bitcoin can't be controlled by some organization or individual.

[DannyHamilton]

energy wasting ASICS,

If the energy use serves a purpose, it is not "wasting".

In the eyes of many moving to PoS would make bitcoin more valuable not less.

Many? Perhaps.  An overwhelming majority?  No.

It's not going to happen. Get over it.  If you prefer POS, go find a shitcoin.

So Christmas Lights have evolved to be more energy efficient ,
why does anyone think bitcoin gets a pass on evolving to be more energy efficient.  

They don't.  GPU was FAR more energy efficient than CPU.  ASIC were FAR more efficient than GPU.  Today's ASIC are FAR more efficient than the ASIC of the past.  Bitcoin equipment is CONSTANTLY getting more efficient, that's WHY old equipment is useless.

Does Bitcoin use more total energy now than in the past?  Sure.  But that's not because it's less efficient.  That's because it's more secure, and because it's securing more value.  Securing the same amount of value with the same level of security with CPUs would use millions of times more electricity.  Bitcoin has only gotten to the value and security it has today BECAUSE it has gotten more efficient.

Efficiency is NOT a measure of how much energy something uses.  It's a measure of how much energy something uses PER UNIT OF WHATEVER THAT ENERGY IS ACCOMPLISHING.  As an example, which vehicle is more efficient, the one that burns 10 gallons of gasoline, or the one that burns 50 gallons?  That's not an answerable question.  If they both drove 1000 miles on that that gasoline, then sure, the 10 gallon vehicle is more efficient.  However, if the 50 gallon vehicle drove 1000 miles on that 50 gallons, while the 10 gallon vehicle only drove 100 miles on it's 10 gallons, then the 50 gallon vehicle is much more efficient.

[TheGreatPython]

Despite news media crying that bitcoin is using too much energy, it's impossible to create a new crypto-coin which uses the same mining principles (so no private companies like Ripple or Visa) but at the same time will use 1% of bitcoin power usage. 1% forever, and not just in the beginning when only 50 people are mining.
Because that would mean that magic coin would cost let's say 1 dollar to mine a day but you would be able to sell it with $100, and that's just not possible. From an economic standpoint.

People never stop talking about this wasting energy thing. Well I do understand the reason why they are always complaining about it. Maybe by the time that renewable energy sources are everywhere, things are going to change and people are going to see it in a totally different way. Although another thing I do think is that everything has their disadvantages. It's just like the other day I was discussing all these different sources of energy with my friends and they were all pointing out the disadvantages of each source.

I believe that solar energy is the right source of clean energy and wouldn't do no harm to mother nature, though one of them did make a statement that solar energy is associated with pollution and indirectly affects our environment. But I think it's far less than what others can cause.
