I'm not an expert, but if 51% of the existing hashpower doesn't want a change, it sounds less a 51% attack and more like miners voting against something that isn't in their interest. The whole point of blockchains is that the incentives are supposed to be aligned between miners and users. If that isn't the case here, it sounds like a problem.
- georgyo 6y agoCrypto miners and and crypto users are aligned in the same way banks and customers are aligned.
- chizhik-pyzhik 6y agoIt is a problem. That's a big reason for moving from proof-of-work to proof-of-stake- to more directly make the _holders_ of Ethereum in charge of the chain. It's a difficult thing to do, though. Hashpower based mining is easier to get going. Proof of stake has issues like the nothing-at-stake problem, where theoretically you could stake-mine on multiple chains: https://ethereum.stackexchange.com/questions/2402/what-exactly-is-the-nothing-at-stake-problem https://ethereum.stackexchange.com/questions/2402/what-exact...

If the asset holders controlled things, why wouldn’t they just demand everyone else hand over their cash? https://www.cbsnews.com/news/richest-1-percent-control-more-than-half-of-all-wealth/ https://www.cbsnews.com/news/richest-1-percent-control-more-...
- drcode 6y ago(1) even a 51% attack can't generate fake transactions to transfer that money (2) social power with blockchains (i.e. having people's ears on the social networks) is far more important than $$ power: If nobody wants to install and use your blockchain, no amount of $$ can fix that.
- akimball 6y agoRe (1): True, in that the committed transactions would not be fake. But calling eth “money” is...not accurate. It has value but lacks moneyness.
- belltaco 6y agoBecause the 1% isn't homogenous and a lot of them will want to keep the system working instead of killing the goose that lays the golden egg. The 1% is about 1.5 million people. Good luck getting most of them organized for a certain cause that will result in destruction of wealth mid term at the latest.
- carlob 6y agoThe 1% Is 1.5 millions iff the 100% is 150 millions, which is what population exactly?
- kubanczyk 6y agoBangladesh? (160 mln actually) I think they could mean a total number of crypto users, recently estimated to be over 100 mln.

I picked that because I didn't think if babies and non-earners were included when calculating the top 1% of highest earners.
- jerf 6y agoThat's a good question. Imagine what would happen if one person held literally all the money. It may be easier to imagine a 100-person community rather than the whole world. One thing that would have to happen is everyone else would develop their own money/currency, which would turn mean that the one person with all the money is no longer the one person with all the money. A thing quite likely to happen is that everyone would decide that whatever the money is that the one person has, everybody would decide it is not money. It isn't entirely dissimilar from me claiming I have all the Jerfoleans on the world, and what the world is really doing about that currency right now. They're worth a zero so zero-y that even an infinite number of them is still worth a flat zero. Someone who has "all the money" might find themselves in a similar boat.
- d0mine 6y agoMore likely the one person would hire some people to convince the rest that it in their best interests that all money belong to the one person or even more likely to provide to the people some distraction, destroy the notion of the facts, so they wouldn't even know to ask inconvenient questions.

- Dolores12 6y agoMoney used to represent the value backed up by gold in bank storage. Nowadays its just a paper, so indeed its easy to create new money.
- jwolfe 6y agoNot that gold has a massive magical intrinsic value. That was also arbitrary.
- gorgoiler 6y agoIt is hard to mine and hard to find. If you make a fresh piece of gold and show it to the world, you are proving that you have done some known — or at least bounded — amount of work. In gold’s case, that work is gas, electricity, and human labor. If someone shows up with gold that cost less to produce, the price goes down.
- ZephyrBlu 6y agoHere's a couple of reasons why it probably wouldn't go this way: 1) Ethereum already has a market cap of $73B [0]. That's a lot of money. 2) Controlling 51% of Ethereum would probably cause the value of it to drop [1]. So you'd spend a lot of money to control Ethereum and then end up with something that's far less valuable than it was before you took control. Not really sure what you'd get out of doing that.

- gruez 6y ago>2) Controlling 51% of Ethereum would probably cause the value of it to drop [1]. I think you're misinterpreting the paragraph. It's not that controlling 51% will cause the value to drop (it won't, see bitcoin miner control), it's that controlling 51% and trying to pull off an attack will cause it to drop.
- ZephyrBlu 6y ago> To do so, you'd need to control 51% of the staked ETH. Not only is this a lot of money but it would probably cause ETH's value to drop To me "it" is pretty clearly referring to controlling 51% of staked ETH. I don't know about the economics behind whether that would cause the value of ETH to decrease, but Bitcoin seems like a different situation altogether since miners don't control the the cryptocurrency itself.
- gruez 6y agoAnd how does the ethereum network differentiate two people with different wallets and one person with two wallets? Short of attaching some sort of real world identity to ethereum wallets it's impossible to tell whether someone controls 51% of staked ETH because it's trivial to split that up.
- bluecalm 6y agoThe article is about wealth, not money supply. Those are completely different concept. There could theoretically be a lot of wealth and very little money (if no one wants to trade there isn't much needed) or not so much wealth and a lot of money (a lot of people need loans to trade and build wealth). It's convenient to measure wealth in dollars in a "how much you could get if you still it" way and it's possible because dollars are very stable but there is very little reason for the amount of dollars circulating to represent existing wealth.
- gonational 6y agoYeah. That's what they do. That's what inflation is. We work hard and save up $100,000, they (the 1%) turn that into $25,000 in 25 years.
- incrudible 6y agoNobody forces you to hold cash for 25 years. In fact, you are given many incentives to invest it, inflation being just one.
- gonational 6y agoThis is true.
- capableweb 6y ago> why wouldn’t they just demand everyone else hand over their cash? Because it's not in their best interest. If the 1% pulled something like that off, the price would drop a lot and therefore their ETH would be worth less. It's one of the core pillars of any blockchain, that the incentives are aligned in a way so the best outcome for people is the one where the gain the most, so it forces them to go for that way.
- discardable_dan 6y agoImagine if you owned a billion dollars, and that allowed you to say if someone spent 10 dollars at the gas station.
- DennisP 6y agoNothing-at-stake is a solved problem in Ethereum's PoS. The basic idea is that stakers' deposits act as security bonds. If a staker commits to two conflicting chains, any other staker can see that they did so, and get rewarded for publishing a proof of that. Then the cheating staker gets their stake destroyed on both chains.
- jkhdigital 6y agoThere is a deeper problem with PoS, which is about where the value of the staked token comes from in the first place. PoW ties this to the burning of real-world value, specifically electricity which is about as close to distilled economic value as you can get. Ethereum is trying to bootstrap value with PoW and then switch, but I have strong doubts that this is a sustainable solution.
- DennisP 6y agoCoin value is not based on electricity usage in PoW. Due to difficulty adjustment, electricity usage is an effect of coin value, not a cause. If coin value goes up, mining becomes more profitable, more miners jump in, and electricity usage goes up. If coin value drops, the opposite happens.
- jkhdigital 6y agoCoin value is a social phenomenon anyway, so it’s kind of meaningless to assign cause and effect. My point was that electricity usage in PoW provides an external metric for assigning exchange value to the coin which is not self-referential, unlike in PoS.
- mratsim 6y agoIt's the same when currencies around the world stopped using the gold standard and became floating across each other. I'd say the value of currencies is that you have to pay your taxes in one that is legal tender. In that case, the value of Eth is that you have to pay transaction fees in Eth. You decided how valuable those transactions are.
- tom_mellior 6y ago> it sounds less a 51% attack and more like miners voting against something that isn't in their interest We also used to call this situation a potential "fork" (as in, the thing with two prongs) before the word "fork" was somehow redefined to mean "protocol update everyone agrees on, with a linear history without any prongs".
- crazypython 6y agoEthereum developers are hard forking Ethereum, but 51% of the hashpower disagrees and doesn't want to go with the hard fork.
- hanniabu 6y agoYup, it's a combination of new people not understanding it and media slander dirtying the word that has caused it to be avoided because it's gained a bad connotation.
- viraptor 6y agoIt's still a fork in both cases. One path is taken by almost noone, but it's still an open possibility to keep it alive.
- JAM1971 6y agoYup. See: ETH Classic.
- jki275 6y agoPrecisely. Vitalik wants to fork ETH (as he's done before when they rolled back the DAO hack) to make a new version of ETH that is proof of stake. The miners, as I've predicted here before, disagree, because this fork obliterates their entire business model. Shocking.
- JohnJamesRambo 6y agoAs an ETH user and holder (and former miner), I want Ethereum 2.0. Describing it as a fork is ridiculous. Proof of stake is the future and miners have known that for years. Proof of work is a dead end that ends with a Dyson sphere harvesting all power from the sun to process a few transactions. If miners want to make another Ethereum Classic dead chain let them do so. The innovation, the users, and all the developers will be on Ethereum 2.0.
- panarky 6y ago> ends with a Dyson sphere ... Just because too much of a thing is bad doesn't mean the thing is bad in lower quantities. Drinking ten liters of water in an hour is bad. That doesn't mean you shouldn't drink any water.
- viraptor 6y agoIt will be interesting to see how the situation develops if they really do attempt to fork and if normal users want to use ETH2. Miners could potentially want to keep the blockchain going and the value could be artificially high, but with transactions falling down and holders migrating, they couldn't keep it up forever... <insert "dis gon' be good" gif>
- arbol 6y agoThere will almost certainly be a split chain that continues to run on pow. Eventually it will die off, like Eth classic
- maxerickson 6y agoThe whole point of blockchains is that the incentives are supposed to be aligned between miners and users. If this were obviously true, there wouldn't be a problem. I think a better formulation talks about distributed ledgers working better when the interests of users and miners are aligned. And of course they never quite are (miners want profit, users want minimal transaction costs with high security).
- Taek 6y agoYou should think of miners as bodyguards. They aren't intended to be active participants on the network, they are intended to provide the service of securing the network and serving the interests of the users of the network. If a group of bodyguards at a concert vote democratically and 51% of them decide the singer shouldn't be allowed to go on stage and sing (because of a grudge or whatever), is that a problem? Yes absolutely that's a problem, and probably all of them are going to get fired. Same sort of idea here. If the miners aren't serving the best interests of the network, the network has no obligation to continue paying the miners tens of millions of dollars per day (no joke, that's how much miners on Ethereum make in revenue right now) to continue sticking around.
- discardable_dan 6y agoThe difference is that a single bodyguard at a concert can quit or not, and likely won't (to pay rent). The Ethereum miners have unionized, however, so now you are negotiating with the miner unions to pay what they think is their "fair share." These people are spending millions of dollars in electricity keeping things ticking away. If they stop, Ethereum's vested interest drops significantly. Since it is a fiat currency, less participants make it, unfortunately, less valuable. Telling 60% of holders their currency (or income toward driving that currency) is not how you keep them on your side, just like old mining town scrip is only worthwhile if the mine works. The second the mine shuts down on a union strike, the scrip becomes paper. On a personal note, I hope the miners get their due, because it was the initial philosophy of Ethereum. If they don't, I am curious to see how Ethereum moves w/r/t proof of stake vs proof of work guarantees. PoS seems at odds with the initial platform, and possibly long-term problematic for their "contracts-first" architecture.
- CryptoPunk 6y ago>>The Ethereum miners have unionized, however, so now you are negotiating with the miner unions to pay what they think is their "fair share." Unlike with employers and real world unions, the Ethereum network is not bound by labor laws to negotiate exclusively with unionized miners, or refrain from replacing them with non-unionized miners. Without those laws, unions are pretty powerless, which is why the late 19th century had such low unionization rates. >>I hope the miners get their due, because it was the initial philosophy of Ethereum. The initial plan of Ethereum was to launch with Proof of Work, and very quickly afterwards switch to Proof of Stake. Miners have already gotten much more time to earn from ETH issuance than was originally planned.
