No one is ever concerned with how much energy is used to feed ads to the entire population of earth 24/7.
Please propose a law or regulation structure for significantly reducing or eliminating advertisements. I’m serious. I fucking hate ads. I just don’t have a reasonable or effective way to get rid of them.
Edit: Hey actually I just thought of one! If the consumer is paying for the product, it can’t come with ads, including things like product placement or ad reads!
ads don’t go unless capitalism goes
Serve ads inside the ads. It’s more power efficient—kill two birds with one stone?
Make sending unrequested data like ads and trackers to web clients a crime akin to gaining unrestricted access to computers. No need for a new law, just a new interpretation on an older one.
Most jurisdictions prohibit unauthorized access to computer systems. What if we just say, “running Javascript code that implements functionality not specifically requested by the user is unauthorized tampering”.

I went and did some mafs.
This thing says the world consumes 180k TWh of energy per year.
Apparently, 48% of consumer web traffic is ads.. That is dystopian in itself, that means around half the content floating around the internet is stuff the client does not request but is pushed to them.
That would put the ad industry at 4500 TWh per year. However, this is back of the envelope.
Going off of this, a high estimate for crypto mining is 230 TWh.
That means the ad industry costs us around 20 times the cost of crypto in terms of power. Feel free to check me because I don’t know shit about most of these things.
That said, this does not account for the entire ad industry, just the cost of sending internet ads around the world. Ads are made, ads are displayed in various media other than websites, and most importantly, ads have the sole purpose of driving further consumption, which all contributes to the societal costs of the ad industry.
Damn, I knew the numbers would be crazy, but that’s absolutely bonkers.
Lets do an advertising tax 10% of all add revenue.
Unironically this.
That’s such a great point wtf
Exactly! Blockchain and PoW are terrible but id really like to know how much time and electricity is consumed to serve ads, cool servers, train and educate people to effectively become ad engineers.
How much does facebook, the banking system Google search need and does it even make sense to compare this against a small country?
That is why I only block ads when I’m on a plane 👍
Or that tumble dryers in the USA alone use more energy than Bitcoin.
Instead of actually talking about it you’re lazily using it to deflect criticism of unsustainable cryptocurrencies. Your input was worthless.
Yea the rally against block chain tech is stupid as fuck. It consumes nothing in the grand scale…do people not realize a lot of large enterprises have ~200k nodes give or take? Bigger companies can have in the million range. 200k machines is a joke.
Edit: I can see a lot of people just hate block chain tech without understanding anything tech wise lol
The nodes aren’t the issue. It’s the fact that those nodes have to expend at least the same amount of energy every single time a record is added and the larger the ledger, the more energy is needed. Blockchain is somewhat unique in that regard.
You do understand what a DB is right? Like there’s millions of them…hell right now typing out this comment has one marking it. And then you’re downloading it to read it… that’s a transaction. Except there are millions of people reading comments constantly on all social media platforms.
My comment here has more bits in it than a single transaction.
With the electricity used to validate a single crypto transaction you could do thousands or even millions of DB queries.
Yes, everything uses electricity. That’s like saying that it’s fine if you kill one cow per day to eat its ear and throw the rest because hundreds of them are killed every day in farms.
Wasting so much electricity in such a non efficient manner so a decentralization cult member can have his wet dream of using non-government money makes no sense.
DBs are not the same as a blockchain. A DB doesn’t have to hash all previous data before it every time the DB is written to. You can read and write to a specific spot in a DB without ever knowing anything else about the DB. With blockchain, inserts have to be successive and they have to reference every previous insert to validate that the entry series is unbroken. On top of that, for things like Bitcoin, every other client also has to validate it since the ledger is shared.
There’s a reason blockchain is significant. Otherwise, why didn’t stuff like Bitcoin exist prior to it? Databases, in some for or another, have existed for decades. Blockchains are immutable, that’s why. The order of entries matters and validation is a requirement.
DBs still update their tables every time someone writes to it. And there are millions of DBs being written to every second. It’s absolutely comparable.
We’re not comparing millions of DBs to a single blockchain. We’re comparing 1 DB to 1 blockchain instance. If you had millions of blockchains, you would use exponentially more energy for the same data vs. a normal database. Updating tables is not the same thing as hashing and validating every prior entry in the table.
There aren’t millions of block chains…lol your argument is bullshit.
You don’t even understand blockchain so I’m not sure what your edit is all about. You’re comparing blockchain to a database in your replies as if they’re comparable.
When it comes to power…it absolutely is comparable…but most of you have no clue how much compute we use daily in terms of power. Acting like the block chain sucks down anywhere near the amount of power we use on even in the corporate world is hilarious…you know a lot of colos have their own sub stations right?
The only person here who doesn’t know what they’re talking about is you. If you took a standard DB (MySQL or Postgres, for example) and took that same information and stored it on a blockchain instead, you’d use far more energy on the blockchain and the issue would only get exponentially worse as the chain got bigger. Normal DBs don’t need to hash new entries or validate them against previous entries that are also hashed.
Yes because there are millions and millions of block chains…lol don’t fool yourself into knowing what your talking about.
And yes DBs are only one DB no one ever has HA stacks or redundancy built in…lol
Are you dense, man? No one said that. They’re saying that one blockchain would take several hundred DBs to equal its energy use. You’re wrong and doubling down for some reason and it’s just making you look silly.
I said that genius…go check my posts…the fuck you arguing about? I literally said that the amount of DBs we have make the miniscule amount of large block chains out there look like nothing. Then you show up and say one DB isn’t comparable to one large fucking blockchain…no shit.
Yeah, people tend hate what they don’t understand. Especially when most people think think every blockchain performs exactly like bitcoin (which is proof of work). Bitcoin is slow and power hungry and would never actually be usable by the masses for everyday transactions. But it was the first and will likely be a “digital gold” for a long time
But it’s not the only one and in time everyone will be using blockchain technology. It’s so much more convenient and useful than most realize. The Solana blockchain has secured a big partnership with Visa that can be read up on if anyone is interested.
The real charlatans were the “the technology has promise” people. No, the technology was dumb.
This is revolutionary
This is de-evolutionary!
…and, hear me out, that will be perfect for keeping messages untraceable by the government. Every single of those 200,000 computers will have full copies of all the messages ever transmitted, unencrypted, but they’ll never be able to tell who wrote them and who they were for.
privacy or secrecy from the government isn’t a goal of Bitcoin - the protocol doesn’t even use encryption.
the goal is protection from (government or other) control
No one who understands bitcoin ever thought it was untraceable.
In the early days it was really common to place messages in the chain.
There are literal marriage proposals among these message.
I’m still 90% convinced it was either invented by the CIA or the NSA for “reasons”. The US military invented the dark web and they even claim to have invented it, so it’s not a far stretch that another US gov. agency invented Bitcoin.
Probably invented as a way to more discreetly fund black sites…

Sure, but what real-world problem does a trustless solve? I thought this was all very interesting years ago but now that we’ve had blockchain for years it seems it’s only good for illegal or morally questionable transactions.

See I think more nuanced takes like this are good. I’m not familiar with the Chinese banking issue that you are describing, but it sounds like deposit insurance (like the FDIC) might be a better solution than cryptocurrency, and it’s definitely better understood. Since the real world value of cryptocurrencies are so volatile they are a questionable store of value, and taking a risk on a poorly regulated bank might be better than taking a risk on storing your money in a volatile and unregulated security like cryptocurrency. Honestly it’s hard to know which is the better risk. So it could be better or it could be worse.
I agree with your point about transferring money internationally, and even within the US transferring money used to be a real pain. So I’m still interested to see if cryptocurrency can be a better medium of exchange or medium of transfer than traditional ways, or at least give traditional systems incentive to improve. But again the volatility is a concern so for most people the best move is probably to get in and out of the crypto market as quickly as possible or else risk getting a vastly different amount of money out of it than you put in. Admittedly it could appreciate, but when I’m transferring money to someone I don’t want that to simultaneously be an investment. The few times I have used Bitcoin to purchase something the whole process has taken hours, and there’s no guarantee there won’t be price swings — a lot could happen in those hours.
I appreciate the brutal honesty about cryptocurrency not being for the average Joe. It’s not that long since many cryptocurrency boosters were hoping it would replace fiat currency, but now that I think about it I haven’t heard as much about that recently. In its current state it is really not for the average Joe.
Legal money transfers are not a use case. Crypto is simply much more expensive to maintain. All these mining rigs and all that electricity must be paid for.
If it seemed cheaper, then either:
the banks were charging inflated fees. That can be fixed only once. (And it should have been fixed by government).ETA: Doesn’t work, after all. It can only be the other 2.- It was masked by price fluctuations. Eventually, someone else must pick up the tab. Can’t work long-term.
- Costly regulations/taxes were dodged.
Under the spoiler is something I wrote recently to explain how crypto is not like stocks.
spoiler
Let’s look at how stocks get their value.
A company sells shares to get funding. Say, you want to make microwave dinners. You need to hire people, an industrial kitchen, packaging and packaging machines, ingredients, and probably a whole lot more. The company takes in revenue from selling the dinners, which pay for the running costs. Anything above that may be reinvested or turns into profit. The profit is paid to the stock-owners to pay them for their investment.
Now the question is: What is the value of a stock?
Imagine you take out a loan. That gives you money right now, in the present. You pay back the loan with the money that you get from your stocks; your share in the profit. Now imagine that the company goes out of business (and the value of the stock becomes $0) right as you are done paying back the loan + interest. Then that loan was the present value of the stock.
In theory, the value of a share is the present value of the future money that you get paid. Of course, one cannot know how much that is, so this is useless for actual investing. Still, the market price of a share should be the best guess of people with money. If the stock is trading higher than someone’s guess, they sell. If it’s lower, they buy. So the market cap should reflect the future profits.
But what’s the value of a crypto-coin like bitcoin?
Let’s start by thinking only about a coin being used to transfer money. And to make it easier, let’s say that coins are only exchanged for money once a day.
Say people want to transfer 10 million USD each day. The senders buy coins for 10 million USD. They don’t care how many coins that gets them, only that the coins represent 10 million USD. If there are 2 million coins being sold on the market, then each coin must transport 5 USD and that will be the market value.
New coins are constantly being “mined” to pay for the upkeep of the system. Let’s say that’s 100,000 coins per day.
The intended receivers of the 10 million USD sell their coins to get the money. The miners also sell their coins to pay their bills. So the next day you have 2 million + 100,000 coins on the market. The senders again want to transport 10 million USD, so they buy the 2,100,000 coins on the market. The market value of a coin is now ~4.76 USD. Adding more coins lowered the value of the coins. That is inflation. The “missing” money goes to the miners to keep the system running. That’s not a problem for senders and receivers. Transferring money costs money, however you do it. (That crypto is an extremely expensive way to do this, is one underlying reason why it has no adoption as a payment system in the normal economy.)
So far, you wouldn’t expect anyone to store or “hodl” coins. The value is just going down. But obviously, this is only true as long as the amount of USD to be transferred stays constant. If the system is more widely adopted and more money is transferred (outpacing the inflationary effect of the newly mined coins), then each coin has to transport more USD and the “value” goes up.
Now, if you believe that adoption continues to grow, it becomes a reasonable strategy to stash some coins to sell them later at a higher “value”. Maybe the problem is already obvious, but let’s continue to take it slow.
So, let’s say, it’s a bit later. There are 15 million coins and they are to transfer 100 million USD. The market price of a coin is now $6.67. (Let’s also say that there are no more coins being mined and the upkeep is paid some other way.) Now we bring in some venture capitalists. One day, they buy coins for an additional $50 million. Now the coins trade at $10 per coin. 15 million coins bought for $100 million + $50 million, right?
The VCs now have 5 million coins. But note where the money went. It went to the transfer receivers when they sold the 15 million coins for $10 each. They got a windfall profit. That’s how it goes in crypto. All the money that people “invested” by buying coins is gone. It was either used to pay miners/for the system upkeep, or early adopters took it and ran. It’s all gone. That’s the big difference to shares.
If the VCs sell their coins again, they lose. Because when there is only 100 million USD in the market for 15 million coins, they would only get 6.67 USD per coin. The money that they spent is gone. If they want to make a profit, new money has to come from somewhere. There are only 2 ways to achieve this.
One is continuing adoption. If more money were to be transferred, with the same number of coins, the price goes up. They can siphon off some of that money by selling into that market. But that lowers the price again, so that only yields a profit if adoption increases enough.
The other is that someone else also removes coins from the market. If there are fewer coins for the same (or a decreasing!) amount of money being transferred, then the market price will also go up. (In this scenario, too, they would be siphoning off money that other people are trying to transfer. The cost of transferring money would be increased for no very good reason; not a great feature in a payment system.) But note that this, too, lowers the price again. That only yields a profit, if “hodlers” sequester the coins sold by the VCs for a higher price than the VCs paid.
I’m not saying this is a Ponzi scheme because everyone has heard that already.
So that’s it. If you want to know the effect of 50k bitcoin on price, you need to look at the trading volume (minus wash trades): How many bitcoin are actually “in use”? You also need to know how many of these coins will be promptly removed from the market by “hodlers”.
Legal money transfers are not a use case. Crypto is simply much more expensive to maintain. All these mining rigs and all that electricity must be paid for.
Various currencies are moving away from the proof-of-work model, FWIW. Ethereum was mentioned in this comment chain as one of them.
Which doesn’t solve the economic problem. (Good for the environment, though)
Ethereum has proof of stake. That means someone has to deposit Ethereum, tying it up. It could be exchanged for money and invested in stocks or bonds, yielding a return. This is only economically feasible if the stake yields the same return as a comparable investment. This profit has to come from the users.
A competing payment system, based on sensible, modern technology also needs computers and the internet but not a stake. It must be cheaper.
The stake is supposed to keep people honest, because it can be taken if fraud is detected. Normally, fraud is dealt with by putting the perpetrators in jail. Being known by name is proof of stake.
Users have to pay extra just so that some kingpins in the back can remain anonymous. Do you want to for that?
It also doesn’t solve the other deal-breaker (in the spoiler). Whenever you transfer money through crypto, you risk that some “investor” siphons off some of it.
How would using blockchain fix the liquidity of a bank?
There’s a case to be made for a currency that facilitates illegal transactions, or transactions that corporations object to. Just because something is legal in your country doesn’t mean it might not be unjustly restricted. Or could just be unjustly illegal in your country or another country. The problem of course is that distributed currency also facilitates things that should be illegal.
But WikiLeaks is a good example - their legacy is a little mixed now, but when they first came on the scene they were doing work which was a valuable service to the public. If you wanted to donate money to support wikileaks you couldn’t because the credit card processors shut them off. Blockchain lets you get around that.
Likewise it’s the combination of distance and direct - I can give $5 in cash to my local leaking consortium, but I can’t give $5 to the leaking consortium on the other side of the world without relying on the knowledge and consent of third parties.
I agree there’s something to be said for this — If you have a above-board business that credit card companies don’t want to service because they think it makes them look bad, that should not shut you out of electronic payments yet that’s basically where we are at least in the US.
This is a little hard to balance with the fact that the same things that let you circumvent gatekeepers like credit card companies also make it attractive for genuinely immoral things, but that’s a trade-off. Every currency can be used for immoral things and just because cryptocurrency might make it a little easier doesn’t mean it’s inherently immoral.
You totally can give cash anywhere in the world. You post it as a letter
This was common before electronic transfer
Mailing someone cash means you need to know their address, you have to wait however long for the mail to arrive, you can’t prove they received the cash, it’s possible the cash was stolen en route and anyone who might wish you harm like an adversary government can observe the transaction.

On account of it being so in yours?
Australia Post says they reject any liability if you do
The UK says you should use their premium service to do so
India says you can’t. It at least quora says you can’t in India
Quora says you can in Canada
I wonder why the UK and Australian searches landed on the national postal carriers and the others landed on fora
I was hoping it would help me save on international transfer fees when I was an overseas postdoc, but it would have actually cost more between the exchange fees and my time setting up all the exchanges in various countries, meanwhile also introducing risk in me being robbed of said money and screwing something up and introducing myself to some sort of tax liability. Needless to say, I continued to just pay for the bank transfers
That’s really the thing, isn’t it? In my experience cryptocurrency fees are quite high. I bet there’s a way to find a lower fee but then I’d have to do a ton of research and hope it’s accurate. I’d rather just pay a bank that requires me to do no research.
It cannot be cheaper, other than by avoiding taxes and regulation.
Consider sending money from US Dollar to Euro:
Sane way: An intermediary (IE a bank) handles this. You give them USD and they give the receiver Euros. This involves some service costs and 2 bank transfers.
Because people exchange money in both ways, the banks need not run out of either Euro or USD. In the background there is the currency market, on which the proper exchange rate is haggled out, which takes care of imbalances in cash flow.
Crypto way: You give a crypto exchange (an intermediary) USD and they give you crypto. This already involves 2 transfers and service costs. One of those 2 transfers is a crypto transfer, which is much more expensive (IE uses more resources) than a bank transfer.
This is already more expensive and then you have to do the same thing again to cash out.
And then we are still not done. Say there is an imbalance in that more people transfer money from USD to Euro than vice versa. That means that crypto becomes more expensive in USD and cheaper in Euro. There’s more demand in terms of USD and more supply for Euro, right?.
That creates an arbitrage opportunity. You can exchange USD for Euro, and then buy crypto for Euro to sell for USD. This closes the circle and puts everything back to the initial state. But to do that, we still have to exchange the real currencies. So now the markets bake the cost of exchanging currency into the crypto prices. At a guess, for some currencies (probably not so much Euro/USD), that would have a significant effect. I’m thinking smaller, poorer countries that send many migrant workers, who send money back home. These workers would not only end up paying the insane overhead of the crypto system, but also, still, most of the normal, direct exchange costs (if they relied on crypto).

it’s only good for illegal or morally questionable transactions.
Good thing laws are always just and everyone agrees that following every law is the most important thing a human being can aspire to do in their lifetime.
^^/s
Seriously though, I’m someone that uses credit for 90% of my purchases, but I also enjoy consuming cannabis and I’m well aware how horrible it would be if it wasn’t possible to make “illegal or morally questionable transactions.”
Also, the unbanked.
Also, privacy and anonymity (to an extent).
Also, complete predictability in the system (its at least domain constrained).
There’s no privacy, it’s an open ledger, only anonymity
It’s a bad way of hiding money if you’re about to be investigated for crime
Monero seems to be holding up in terms of privacy.
Thanks for your input, dingdong.
Bingo. Capitalism has thus far rejected the blockchain, which is generally evidence that it doesn’t solve an important problem either efficiently, safely or cheaply.
To be fair, there are plenty of other reasons capitalism might have rejected blockchain: market failure, interference by government, etc.
I’m not saying that to defend cryptocurrency, by the way, but rather to point out that capitalism isn’t perfect at allocating resources in every situation.
Isn’t one of its goals to be free from government influence? That’s not a valid excuse.
Blockchain is just a technology. It doesn’t have “goals.”
deleted by creator
They put money in Bitcoin, but not the tech behind it. To them it’s just stocks to be manipulated in order to get a profit.
I don’t know why this is surprising. Capitalism is an economic system where the goal is profit. So, why would capital do anything other than seek profit? Nearly all technological advances have occurred through government or institutional investments, then capital flocks to it when someone finds a way to profit from it.
Thinking block chain is a solution to anything is naive. It does nothing to change the underlying system, or the incentives that drive our economy. Like any system, the interconnections between the things that make up the system, and the goal of the system must change otherwise everything will just settle back to the status quo.
For example: media streaming is becoming cable tv again. Nothing fundamentally changed about the system of delivering media, or the goal of the system which is to drive profit. Thus, we are moving quickly back to the same model of paying for media (renting it really) and watching ads to increase the revenue of the provider
Bitcoin had its official ETF approved and started the other week and Ethereum is soon to follow. so I would say capitalism is very much not rejecting blockchain technology. Didn’t blackrock and other giants put a ton in?
Right?
Also, look at its price. It dipped, and came right back.
If anything, the financial consensus around this is exactly the opposite of what was being presented.
With all the information available at your fingertips being ignorant is a choice.
“this parallel financial system can also serve a tangible social good, offering an onramp to the financial system for people who would otherwise be left out. In countries where the vast majority of the population is unbanked, national currencies are no longer a safe store of value, remittances comprise a hefty portion of GDP, and international sanctions complicate connections to the global economy, a virtual currency that doesn’t require an intermediary to approve transactions can be a vital lifeline for survival”
Bitcoin is poised to blow up Africa’s $86 billion banking system
This isn’t Reddit, you don’t have to turn every discussion into a fight. I’m genuinely interested in cryptocurrency for reasons such as the article you linked: there are areas where traditional finance genuinely has failed to meet people’s needs. Providing a medium of exchange for the unbanked is a great example of something it could possibly help with, and I think that’s a good thing if it happens. But we should also be able to talk about the problems with cryptocurrencies and the cases where it doesn’t work as well as traditional finance. And if this prediction doesn’t pan out and cryptocurrency doesn’t become a major way of banking the unbanked, we should be able to consider what could accomplish that goal. It might be a different cryptocurrency, or a new thing inspired by cryptocurrency, or something that has nothing to do with cryptocurrency. After all, cryptocurrency is not a goal in itself.
I’ve never been in Reddit so I can’t talk about it but I wouldn’t have been so harsh if you hadn’t already stated that it seems only useful for illegal and immoral activities when it’s so easy to find, if you are “genuinely interested”, that it’s not the case.
Crypto =/= blockchain.
If you can’t see the utility of blockchain with regards to things like actual, verifiable digital ownership, then I don’t know what to tell you.
I want to see what you mean in practical terms, because the only other example that I know besides questionable crypto currencies is NFTs and that was an epic lesson on what not to do. 😅
No, NFTs do have good uses, but things like image NFTs are just a misappropriation, like SPAM is to email.
One use case, is clear, independently verifiable ownership of non-tangible things, like Intellectual Property rights. Movie rights for a book adaptation for instance moving between companies in IP sales and mergers/acquisitions.
IP rights is not a problem that needs solving. In fact, the existing legal system has ways of punishing copyright violations whereas the Blockchain does not.
Supply chain validation is also an example of the block chain “in action”. But the people that are entering the data on the Blockchain are the same people that were typing it in an email yesterday.
I used to be a fan of the technology as well but so far it hasn’t show itself to be useful. A solution in search of a problem.
No, NFTs do have good uses
I hear that now since 12 Years. Its not going to happen.
And it’s ALWAYS the same problem. You can have all the lists you want. A central authority has to recognize and enforce that list. At which point, the structure of your list is completely irrelevant. It could be ANY list. What matters is that it’s chosen to be enforced. And currently, most power structures are happy with plain old databases. Or pen and paper.
I don’t know the value in a decentralized IP rights system. If the key holder gets phished, you can lose your rights to a TV series you’ve been working on. (Like Seth Greene)
He wouldn’t have lost it and had to pay back the ransom in a traditional contract. Having a contract centralized and enforced by the legal system has many perks and I can’t ever see how a decentralized rights platform can enforce itself.
"Intellectual Property[sic]" is dishonest loaded language, but yes, I agree with you that blockchain could be a good way for a copyright holder to prove their monopoly. 'Course, that’s also what registering your copyright with the Library of Congress is for, so…
There are other uses. Like making a system that is interconnected and resistant to hacking. For example an interconnected traffic light system that can prioritize transit/emergency vehicles could be managed by a block chain to ensure the system stays in sync with itself for traffic flow/prioirty while being resistant to hacking or malicious activity.
How does adding more computers, more points of failure, make infrastructure less prone to exploitation?
Because it’s a trustless system. In order to override the system you have to take over 50% of the nodes, and in large enough systems it’s infeasible to get that much compute power. This means that no one person or organization can actually control the destiny of the system, only the consensus can.
I can’t believe that here, in the fediverse of all places, we need to have a discussion about the benefits of having a system that corporations can’t control.
Who controls the streetlight blockchain in your idea? You think the government is going to responsibly manage a system that is large enough to be impractical to alter? My local government is barely responsibly enough to manage basic utility maintenance, we’ve had 3 water main bursts in a month and it hasn’t even been below freezing that whole time.
I can’t believe a human being living in the world doesn’t see that any implementation of a secure blockchain requires massive funding for infrastructure. That money comes from 1 of 2 places, illegal enterprises that maintain control for security and manipulation, and legal corporations that will maintain control for financial security and manipulation. Modern governments don’t run projects like this anymore, they contract them out to corporations.
Keep in mind that the only practical use of blockchain that anyone has found so far, has been as a currency that requires no ID. The most famous use of these currencies was by John Mccaffee, who used crypto currencies to help him evade authorities for nearly a decade. So I don’t have much faith in a technology that has only shown a benefit to criminals with so much money that cash becomes impractical. Nor do I have to remind you that wealthy private individuals have been able to manipulate crypto markets with hilarious ease, like how Musk pumped and dumped Doge Coin years ago with a single tweet and most likely made millions in private, untraceable money.
Just because something sounds cool on paper, and makes it seem like it skirts governments and corporations, doesn’t mean it works in practice. Large entities inherently have more resources, and are primed to steal new technologies for their own use, especially when implementing that technology requires huge funding for infrastructure.
Yeah I realize now I responded to a thread about traffic lights instead of systems in general. Obviously centralized systems are far superior for that.
This is a classic solution in search of a problem. The problem with stop lights isn’t that corporations control them, the problem with stop lights is that the general population thinks that cars are the only way to get around and demand that city officials optimize street and roads for cars. Adding a bunch of crazy verification steps will not solve this problem.
This is another social problem that technology just can’t solve.
How about first we see a version that isn’t a scam? We’ve seen plenty of scam versions so far.
IMO, blockchain technology is good for one use case: illegal transactions.
I think all else can be achieved more efficiently by using a trusted third party write-only database, such as the ones available on AWS, and you’d also have the benefit of being able to go to court to seek relief. Some blockchain markets are basically reinventing banking systems and preexisting financial law - systems that have been built over centuries and have quite a bit of knowledge baked in.
I do like the shift to proof of stake from proof of work, but this tech is silly to me.
I know of one use case that seems viable, there is a digital housing market service in my country (called Dias). It uses blockchain to verify transactions related to selling and buying houses. That includes proof of sales, ownership, bank transaction status etc. The blockchain is operated by all the major banks. Their incentive is that it increases the security of the transactions thanks to the immutable digital trail, and also the fact that no single entity owns the “database” so no entity can alter it, or skim service fees etc from the others.
But if you have any conflict with it, you have to get a lawyer involved right? It doesn’t seem like it provides value to a real estate transaction, just seems like a use case for block chain
A blockchain is only as secure as the amount of work (= processing power) that goes into it. Anyone with 51% of the processing power invested in a blockchain can attack it and essentially steal from other people. For cryptocurrencies it’s a problem that solves itself, because every person that possesses some of the cryptocurrency is incentivized to mine to keep it secure (and to earn some at the same time). The more your cryptocurrency is valuable, the more people will want to mine it and the more secure it will be.
For anything other than cryptocurrencies, you can’t incentivize a huge number of people to commit computing power to secure your blockchain. So you have to protect it some other way, for example only allowing you and some trusted people to write on it. But then it doesn’t really need to be a blockchain anymore, just a write-only database (which will perform better and occupy less space).
If it requires no work to generate a block at the end of your blockchain, any attacker can generate malicious ones.
Digital ownership on one (1) blockchain. Not really that great when you put it like that. What makes one Blockchain more authoritative than another? Even in a closed system, if you think the admins of these chains don’t keep a kill switch in their back pocket specifically for their advantage in ownership conflicts then you should probably read about Ethereum Classic. Even if they don’t want to hard fork, if a chain is controlled entirely by a company, then they can edit it however they want regardless since it’s not really decentralized. The idea that Blockchains will empower the customer with digital ownership is silly to me.
In a trustless environment…
You’re handing over your valuables at gunpoint, nerd.
I think you meant to reply to a comment and instead replied to the post.
No, I’m just mocking Blockchain idiots in general.
Then some massive org like the NSA creates/captures 51% of the nodes and takes everyone’s money overnight.
The coins can only be stolen for as long as the 51% attack stays live.
Ignoring the fact they definitely have the resources to sustain it, how many people will continue to run a node after losing everything to such an attack? How will anyone reclaim real world value if they exchange the coins for something else?
Coin holders would only lose everything for as long as the attack occurred. The validated chain would still correctly record their claims.
The people receiving the fake coins transfered during the attack are the ones that will be pissed. Any goods or services exchanged during that attack period may not be compensated.
Again, how many ordinary people will continue to run a node for a network where they have nothing for an extended period? Even if they do, will the value of the coins remain even after such an event proves the weakness of the system?
Empirically after a 51% attack, 75% of people stopped mining.
will the value of the coins remain
Eth classic is currently $25.
It doesn’t require that much computing power, that’s just a variable that gets set.
If the difficulty were set lower, one average computer could easily handle it.
Oh sweet. Let’s just set the difficulty lower, then.
But then every jabrony would be able to make money.
So, in other words, it does require that much computing power.
You too can learn this secret of the ages! You just need to be able pay for my one hour Webinar and Goon on camera for at least three!
Setting the difficulty to use mode power level now below 50% the earth is saved
I love how one man created arguably the most complex puzzle in the history of mankind and people shit on it just because it’s literally hard to solve (aka “uses energy”) and the solutions have value.
What value is that?
Wow, I thought I was back on reddit with the tech fear mongering.
A single Ethereum transaction now uses only 0.02 kWh of electrical energy and has a carbon footprint of 0.01 kgCO2, which is much lower than the average values for a debit transaction or PayPal.
For anyone who’s interested, Holochain solves this problem while fulfilling the decentralization promises of Blockchain.
