OK but there are actually great uses for blockchain that are completely disconnected from anything you typically see
For example, banks may begin using blockchain for maintaining their internal ledgers. It will help solve a ton of issues around reconciling the transactions from all over the globe
Blockchain has reasonable uses. Really good ones. Crypto and nft bros just completely ruined the image of it
EDIT: I love all the comments demonstrating how little people understand about blockchain. Bitcoin was not the first blockchain, nor is its design the only type of blockchain. Assuming that all blockchain looks like the crypto/nft paradigm is just showing your ignorance.

Blockchain is only potentially useful if there’s no single entity that can be trusted. If banks can’t even trust themselves to manage their own internal ledgers, they have much bigger problems to deal with.
Trustless systems aren’t a bad thing that has to step in when the good thing fails. Trustless systems are inherently better because you don’t have to trust a bank (or anyone for that matter).
Additionally, ledgers can be gamed/corrupted/falsified. This is significantly more complex (bordering on impossible) on the blockchain.

There are often easier, more reliable, and far cheaper ways to achieve the same things without using a blockchain. Some of the principles are even used in normal web browsing to ensure secure untampered connections.
Blockchain just solves a subproblem that only arises when there’s no appointed central entity.
Blockchains aren't hard, unreliable or expensive
Cryptocurrency Ledgers can be corrupted?
That's the thing, they shouldn't trust a single source of assumed truth. If the single source is tampered with, there's nothing to compare to.
Removing the need to trust a single entity is just a great security feature
You can implement public or semi public ledgers without Blockchain. That's what banks are doing already by sending huge CSV files internally and externally. Blockchain is not a technology of zero trust. It's close to the opposite. You trust a few peers and blindly trust everyone they trust. That way you trust a network that you know nothing about and if the network decides on a common truth that you are convinced is incorrect, there is nothing you can do about it. The consensus always wins and there is no single entity to complain to and get it fixed. This is great for making sure that many actors need to be bad actors in order to have the whole system fail. It's bad if you don't trust anyone and want to make sure that your standards are always observed. From a technology standpoint I love the concept of Blockchain. But use cases that are not forced are few and far apart. Too few for the amount of hype it receives.
If the bank can’t even trust themselves then there’s no point in having the bank at all.
You really don't get it? Trust is a problem. Anyone, or anything, can and will fail or be compromised.
so I put my trust in software instead. And by extension its developers. You're saying of all people, we should trust some programmers above all else. You know, the "move fast and break things" guys.
As a programmer myself, this thought is both terrifying and hilarious.
Blockchains is a tool for moving trust around in a decentralized network, not a tool for removing it.
Yeah let’s use the computing power of an entire country to pay for a small coffee.
Yeah it's called a database....
There aren’t a lot of distributed databases with no single owner and all writes are signed.
Yeah, but not having an owner is actually a fucking terrible thing for a banking system, how do you not grasp this?
you’ve just demonstrated your lack of depth of understanding of blockchains. congratulations, your opinion was correct about 15 years ago. the technology has moved on
and the "solutions" are all objectively worse security wise. And by thinking blockchains need proof of anything, you too misunderstand what a blockchain even is. Proof of whatever is needed by the concensus algorithm, not the blockchain.
You say so but I guess it's hard to convince a lot of people who recognize it's folly to try to fix a social/human problem with a technological solution.
Git is a merkle-tree based system like a blockchain. People have no problem with the tech. They're just tired of the hype train.
How is the blockchain different from a read only ( write only once to be specific) DB that follows ACID?
Blockchains add cryptographic signing and limit actions based on those signatures.
Why would you want the computational power of a bank system have anything to do with whether it's ledger is correct?
Banks/hackers can manipulate data if they want to. Manipulating data on blockchains is way waaaaay harder.
Using a blockchain to maintain their internal ledgers means they have complete control over that blockchain, so they can manipulate it all they want. Blockchains aren't magic.
How do you see memes like this? Because I see them as lame and sad, especially since we have been seeing them for 10+ years now and they are still the same. But apparently you think blockchain has reasonable uses.
i for one would have liked a media licensing system that operates agnostic of any centralized authority
for instance, irrefutable and independently verifiable proof that you own a valid software, music, or visual art license and are therefore immune to prosecution for piracy.
A registry of licenses like this could shield creators from copyright claims on social media applications such as youtube. Could also automate revenue sharing and royalties for artists whose works are used in derivative media so the people who actually perform the work get paid. Would be nice to cut the publisher middleman out. And there is absolutely no reason there has to be anything like a "proof of work" system burning down entire fucking rainforests' worth of energy to verify every single gods damned transaction because this sort of system isn't for trading shit, it's strictly for proving a valid chain of custody between producers and consumers and you don't need megawatt-hours to just fucking LOOK SOMETHING UP.
imagine if, for instance, fucking warner brothers couldn't "takes backsies" content that they SOLD to end users through a distribution network; the license is yours, and anyone can look up the fact that the license was sold to the user id you happen to control.
imagine if, for instance, you buy a video game through a digital distributor like steam but then the store goes out of business and no longer exists to serve you a copy or recognize the sale, but on this massively distributed and decentralized database you can prove that you did indeed compensate the developers of that software and thereby legally acquire entitlement to access it in accordance with the end user license agreement.
imagine if ownership of stuff you bought fair and square can never be taken away from you
THAT'S what we could have had
instead of this fucking bullshit.
I feel like here you get to the NFT problem of having proof of ownership of something doesn't mean much when that thing is being hosted on servers you don't control
so if you have an entry with a licence for a steam game, and steam gets closed, you are out of luck
It's like if losing your wallet automatically burns down your house. Sounds amazing, let's do it!
What you're arguing for is forcing the distributor to distribute in perpetuity, which has nothing to do with how you show ownership of your license.
Right now, I can show steam I've purchased, say Delistopolis, and they will agree I am indeed perfectly allowed to have and play it. But they are not required to provide me with a copy.
A blockchain system will not solve this.
All such copyright licenses are rooted in local jurisdictional law, so your country's copyright office should be the authority because anything else means the courts can tell you that your on-chain transactions are invalid
Well, if those licenses are entries on the blockchain, they could be transferred on the blockchain. You could sell your game used when you’re bored of playing it. You can’t play it after you sell it but someone else can. Publishers hate resale markets though, when people buy used games they don’t make any money. So they’ll probably never go for this.
yeah on top of that, if your computer breaks or something now you lost all of your keys.
say goodbye to whatever you own on the blockchain when the keys are gone. poof!
this is the biggest problem with any scheme tying private keys (digital) to anything in the real world.
Once my mom threw out all the cases for my computer games and put all the disks into a cd binder to save room.
It was devastating.
blockchains do not do jack shit with reconciliating records.
Please go and attempt understanding the thing you are talking about before talking about it.
