is there any legitimate use of blockchains?

Hello,
I have been researching about blockchains and stuff and it all seems like a big scam. It's not sustainable and can be replaced by a simple database.
is there any legitimate use cases of blockchains or it is all just a big scam?
Gods unchained is a digital TCG that is the only good use of NFTs (and thus Blockchain) that I can think of.
The idea of NFTs is you have a specific instance of a thing that you can trade around. NFT art is stupid, because at the end of the day it's a jpg. However, with a digital TCG, each NFT can represent a singular copy of a digital trading card. It brings back the "trading" aspect of a digital TCG, made more convenient than physical cards due to digital transfers.

But them the government can't unilaterally take your property from you for a pittance under eminent domain. Who wants a system like that?
Yes they could? Just append a block with the government stating they now own the land.
I guess you could fork the blockchain and don't accept this change but this would be useless. Even if no one accepted the claim, the government can just do whatever they want with that land.

Git uses blockchains to store pretty much all of the worlds software...

No a blockchain is a chain of blocks. Its an append only datastructure that provides a cryptographically verifiable history. Proof-of-work is what allows for public concensus in crypto currencies like bitcoin, where as git uses signed blocks to identify different chains.

Whereas voting with a piece of paper can be tracked and validated by a severely myopic 6 year old. And you can recount it. You can't "recount" a blockchain if that's your only source.
And if you do both, then why bother with the blockhain?

What are you trying to say here?
If each vote is a block in the chain them it is definitely recountable.
If I get a reciept of my vote's hash in the chain, I can confirm it's being included.
The real issue with using a blockchain is it would anonymize the process.

They already are in most countries. E.g. in Poland land registry is maintained by court system and any changes are made only as a result of court order or a filing made by a notary public, who has a real incentive to check all the documents, because they are on the hook financially for any false filings.
In other words, this is a solved problem without any blockchain nonsense.

That's not what it means. With this system, you can't independently verify what happened. You can only also look at the blockchain and see that some hash has registered some vote.
But you don't know if that is actually true. You can't see if pushing the red button makes the red vote come out. You can manually count if you want, but the original billet doesn't exist, only a processed form of it on the blockchain.

Only THAT it's included. Otherwise you have something linking you to your vote, which is bad

Most techbros trying to sell the Blockchain are just ponzi schemes/scams. It does have a legitimate use. But not for whatever the techbros are yapping about. It is essentially a decentralised database under nobody's control.
Exactly, and such things that require or could be improved by decentralized systems tend to be managed by companies (monopolies, or close to it) that already are acting like enshitifying goblins instead of responsible curators.
The ticky part is that when these decentralized systems are involved, the true costs (power, hardware, network, etc.) are distributed and not easily collected.

Could you elaborate a bit how blockchain enables something unique here? I see that it enables trade between users, but if a single company controls the game and I assume supply of new cards, does the blockchain aspect for trading really matter?
Trading itself is basic and doesn't need a blockchain. I guess with it you have it implemented in a public and tamper proof way, but that second part doesn't seem to matter to me if the source is centralized.
So what exactly is gained from this approach over just your average ingame auction house?

In theory you could use them for ERP systems like SAP to track components in global supply chains

There is debate over whether a git history is a blockchain or a DAG (Directed Acyclical Graph). I'd say it was the latter.

i feel like the only real 'advantage' here would be that the cards couldn't be proxied which sounds like only an 'advantage' to the people on the rent-seeking end of the bargain.

Git doesn’t sign commits, at least not cryptographically. I can download the Linux git repo and add whatever commits I like to it. I can even create my own commits under Torvalds’ name and email if I’d like, or rewrite all his commits under my own name.
It’s highly unlikely I can fool anyone it’s the real deal though. They will just download the kernel from the official repo instead.

Anything that requires a public, immutable database. Land registry would be one example. Notary public for electronic documents would be another.
You can leverage the majority consensus to create a trusted software build system. Each block would be a package build
If you have to have someone enforce the land registry or the documents, what is the benefit of the database being zero trust?

Like most of the tech bro industry, they take something with real value, completely misunderstand it, creates fake value, pumps.
LLMs are awesome, but the current AI industry is terrible and completely misses the actual value of LLMs.
NFTs are actually a great way to digitally prove ownership, basically the future of digital ownership certificates.
Crypto is a way to make money for the people by the people, and not for the rich, by the rich, through the people.
Blockchain is the core idea that makes crypto and NFTs possible. You can think of it as a decentralized DB, it's useful because it means that the majority controls the data and not a centralized authority.
Imagine that the government decided to print a million dollars and give it to some politician, it's small enough to not be noticed by the market, but it still devalues the money. They could only do it because they own the money management system. In Blockchain each transaction is confirmed by external parties (often multiple ones) and it has to align with the already existing db (which everyone has a copy of) so in that scenario if the government tries to "print" money it will be conflicting with the existing db and it will not be accepted, so they will have to either continue with an incompatible db (making it as worthless as monopoly money) or cancel the transactions by realigning with the common db.
Blockchain is not meant to be a database like the ones in web servers, it is meant to be a database for a consensus of users.
because it means that the majority controls the data and not a centralized authority.
Only until it doesn't. A centralized authority could overwhelm and become the majority. Or more concretely, the US government has the resources to more than double the contribution to Bitcoin, thus giving it complete control.

also you can only guarantee the records have not been tampered with if you maintain a full copy of the records to compare. Even if you do have that full copy you will have a problem proving your copy is the correct one. A full crypto-verified ledger solves that.
If you empower e.g. every change filer (court, notary public) to run a node fudging records becomes effectively impossible.

Usually, lag like that is due to an ancient codebase, database, and process setup. If you were to solve that, you still wouldn't need blockchain. The software and process engineering does need careful consideration--almost all the stuff like this has had at least one major attempt to replace it over the decades, and it obviously failed--but again, nothing you would be able to solve just because blockchain.

How is this different from MODO?

wrote last edited by [email protected]The money required to double the bitcoin hash rate and maintain double is immense. It's specialized hardware that would need to be manufactured (lead time while network continues to grow, plus who even has the capacity to do that other than TSMC or Samsung) and the network would see it coming and have a chance to do something about it.
It was a risk when it was smaller, but the ability to pull an attack off like that now and maintain the attack isn't practically in the realm of possibilities. (Edit and that's not even getting into where they'd get the power to power the network which is estimated at 173Twh a year and the need to keep expanding that power to maintain the attack in adversarial conditions.)
Attacking the network in other ways via corrupt laws with multi government cooperation would be far easier.
