I’ve read that blockchain itself is a good technology. NFTs are a laughably absurd attempt to exploit that technology for profit.

Xitter op needs to shut up.

It's one of those things where scientists discovered something interesting and novel, and then a bunch of dumb grifters came in to try and make it their new snake oil.

A very, very long time ago, back when Bitcoin was viewed as a currency instead of an "investment" platform, Bitcoin kinda fulfilled the ideal use case for the blockchain. I think now the general public is just too soured on them for that to ever be the case, unless Elon makes Bitcoin the new currency of the U.S...

I seriously think his plan is fuck up the US economy so bad that the dollar hyperinflates.

[–] uis@lemm.ee 1 points 12 hours ago

Don't worry, other countries won't let it happen because their economies are held hostage by US.

Blockchain is a solution in search of a problem. A way to establish trust while not trusting any party is a cool concept, but in the real world it's far easier to establish a source of trust.

[–] stebo02@lemmy.dbzer0.com 24 points 1 day ago

It is a bad solution though, because it revolves around wasting tons of energy in solving made up problems no one actually needs the solution to. I know there's alternative cryptocurrency that use better methods or solve actual problems but 90% of it is bitcoin.

Congratulations, now your trust relies on your subject never becoming important enough that someone bothers to run 50%+1 of the nodes in your network which means only very, very large subjects (or ones where trust wasn't very important in the first place) ever even have a chance of that not happening. What do you say? Your technology doesn't scale to very, very large subjects because of abysmal transaction rates?

Yup. Very well said. People don't realize the extent of wealth inequality (and how ridiculously resource intensive blockchain tech is). If anything important were to be decide by a blockchain, the top 1% would control the network.

More on wealth inequality here.

Today's inequality was created by the Cantillon effect.

I have a friend who works at a major bank and they use Blockchain technology to keep track of something or other internally, though I don't remember exactly what. In this case at keast we can bet that it has found a problem wirth using it to sokve. Banks are nothing if not efficient.

I find it funny that it was touted as an alternative to the current banking system and ended up being absorved into it though

[–] lurklurk@lemmy.world 7 points 1 day ago

I envy your trust in the efficiency of banks

[–] Blue_Morpho@lemmy.world 5 points 1 day ago (1 children)

Banks are nothing if not efficient.

Banks are businesses made up of people. If a manager thought he could get a promotion by supporting a blockchain project at the height of blockchain mania, that's what he would do. Whether if fails or not is of no consequence, the manager is already on another project.

[–] Trainguyrom@reddthat.com 1 points 20 hours ago

My experience working in banking is that they're extremely conservative. They don't take big risks on new technologies or processes and don't modernize their technology too quickly to be certain that everything works as expected and doesn't surprise anyone

[–] sik0fewl@lemmy.ca 5 points 1 day ago

If it's used internally, then I question whether it made sense to use blockchain. At the end of the day, it's probably the trust in the bank that matters and not blockchain.

What problem does blockchain solve?

[–] cRazi_man@lemm.ee 113 points 1 day ago* (last edited 1 day ago) (1 children)

Having too much electricity and not enough CO2.

[–] taladar@sh.itjust.works 19 points 1 day ago

We recently developed AI for that purpose though which does the same thing but is useless in occasionally funny ways.

[–] magnetosphere@fedia.io 26 points 1 day ago (1 children)

Apparently, it can be very secure. If “pieces” of a secure key are stored in multiple places, for example, only changing one link in the “chain” means it won’t match with the others. They ALL have to be changed at the same time, which is virtually impossible to do in secret.

Please note that I am far from an expert on the subject. I’m paraphrasing an article I read months ago.

[–] hddsx@lemmy.ca 21 points 1 day ago (10 children)

Can’t you takeover a blockchain by owning the majority of a block chain, or by having a majority of the processing power to compute hashes?

[–] KazuyaDarklight@lemmy.world 37 points 1 day ago (1 children)

Yes which is part of why the major chains are owned and controlled by companies, but then that makes the whole thing pointless. IMO, a company controlled blockchain may as well just be a DB cluster, it would be faster and more efficient.

[–] hddsx@lemmy.ca 13 points 1 day ago

Are you saying that they “solve” that by never giving up more than 49% stake?

That… seems like a bad solution

Essentially, verifiability (the token exists on the blockchain), de-duplication (each token can only exist once on the blockchain), and proof of ownership (only one account number can be associated with each token on the blockchain). There's nothing wrong with this idea in a technical sense and it could be useful for some things.

But... the transaction process is computationally expensive. For the transaction to be trustworthy, many nodes on the blockchain network must process the same transaction, which creates a whole bunch of issues around network scaling and majority control and real-world resource usage (electricity, computer hardware, network infrastructure, cooling, etc).

And beyond that, the nature of society and economics created a community around this unregulated financial market that was filled with... well, exactly the kind of people you'd expect would be most interested in an unregulated financial market - scammers, speculative investors, thieves, illegal bankers, exploitatitive gambling operators, money launderers, and criminals looking to get paid without the government noticing.

The technology can solve some interesting problems around verifying that a particular digital file is unique/original (which can be useful, because it's extremely easy to make copies of digital information) but it creates a long list of other problems as a side effect.

[–] Tar_alcaran@sh.itjust.works 4 points 1 day ago

Almost every single non-theoretical problem that blockchains solve is something we've already solved. And most of the problems you could solve with a blockchains are severely limited by data-size limitations.

It would be amazing if I could decentrally store, say, a movie or videogame on a blockchain. Then, I could sell access tokens, would the owners could resell as they wanted. That's a GREAT way to use blockchain tech, because people would always have access, and they could use or sell the keys as they wanted. It doens't work though, because in the real world, that movie doesn't fit on the blockchain, it'll just be a link the a secondary source, and the whole thing falls apart.

And that's really the problem. Blockchains have a lot of nifty uses, but it almost always immediately falls apart around the edges, where it touches on non-blockchain tech, or, even worse, physical objects.
