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?

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.
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.
It’s cheaper and easier to manipulate the stock markets through politics than to build/take over the majority of the distributed ledger.
Nothing is perfect, but once a blockchain network is big enough it becomes near impossible to overtake.
Maybe currently, if the US government really wants to, they could dedicate a few trillion dollars to take over the bitcoin network. But it would make no sense to put that much effort into what would be mostly pointless. And if bitcoin ever reaches a point where it is a full on threat to the dollar then it’s network would probably be too big for any nation to overtake alone.
So you are not wrong in theory, but in practice it is near impossible.
The conventional wisdom is basically that that’s never going to happen, though, and the barrier to becoming the majority is strong enough to stop any actual attacker.
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.
