Yes. Decentralised certificates (NFTs) for the likes of digitally owning something non fungible (think like a concert or plane ticket that isn't tied to Ticketmaster, etc), or more commonly, cryptocurrency. A way of storing wealth digitally without anyone controlling it centrally.

I would argue against this stance, but not completely. The need for decentralized authorities only comes about due to a lack or trust or failure of the custodians of the product.
From your example, you could turn concert tickets into verifiable tokens (I do think this would be a good idea), and it would solve a lot of after market sale and validation issues. The only reason we have these issues in [checks current year] is because monopolies like LiveNation/TicketMaster have so throughly turbo-fucked the system that venues and customers cant do anything about it.
IMO, blockchains are a cool concept, and I love that cryptography is now a common topic of discussion because of it. However, its a solution looking for a problem and the problems up until this point are manufactured by the people selling the product or straight up ponzi schemes.

People will easily list a lot of credible legitimate usecases
that are hypothetical
and have remained hypothetical for 18 years.
Being on Lemmy, I like the idea of decentralized and permissionless stuff, including money. The problem I have with crypto is that they're either clearly scams (Trumpcoin, Melaniacoin etc) or they were not intended as a scam but the market fails to fairly price them because they speculate (e.g. Bitcoin).
Also I don't understand why people keep insisting in buying Bitcoin when the energy to "produce" it is enormous and is responsible for a lot of CO2 emissions when there are greener cryptocurrencies.
@tired_n_bored @Deestan the mining aspect is what makes it secure.,. In theory Proof of Stake is greener, but once someone archive 51% of stake he became the owner of the network, while with proof of work the cost of securing the network is permanent... Saying this, i do agree that bitcoin energy spend is ab issue...

Yes, your honor. My buying of drugs online was only hypothetical, it never happened.
Basically, no. At least, not until everyone has the knowledge and resources to run their own compute, which is never.
Decentralized systems must be accessible and maintainable by the majority. Blockchain is neither of these. It's also why the internet moved to platforms rather than remaining as many niche forums.
Additionally, network effects and economies of scale make decentralized systems difficult. See Lemmy. Even here, World is the biggest because it's simpler and easier to do everything in one place. People don't have to make decisions. People don't have to do their own work.
Basically, human psychology and economics suck
They are a write only database that doesn't rely on a centralised point of authority.
Transactions are a perfect use case and objectively better than the current fiat currency method. Unfortunately the pure intentions based in cryptography and mathematics has been spoiled by grifters trying to make a quick buck.
Monero has stayed true to the ideals of crypto completely decentralised. Truly anonymous. Faster than fiat. Cheaper than fiat. More power efficient than fiat. Real value tied to real goods not just a speculative asset.
Sure, there are a ton of things the blockchain would be great for. Also, it just so happens that nobody uses them for that because the people developing the tech only dream about using it to join the bitcoin billionaires club.

Just a big scam.
The only remotely valid use case I ever head was for a Write Once Read Many (worm) audit log but regular databases are still a better fit.
That's effectively what git does.

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.
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?
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.

No way. There are many ways to introduce artificial scarcity to digital goods, and no it is not a new or good use of the tech.... Artificial scarcity is a huge part of all of the world's problems.
