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.
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.
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?
now your trust relies on your subject never becoming important enough that someone bothers to run 50%+1 of the nodes in your network
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.
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
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.
Nah. the commenter above is just wrong. It’s just that anyone who isn’t selling bullshit uses their real name- Merkel trees - which are fundamental to modern software development (git, zfs, nix, nosql).
Is it easier to establish a source of trust? With blockchain trust lies in the protocol and in the node operators who make decisions about how to operate their nodes. Running a node isn’t extremely difficult. Running a financial institution is difficult.
Well, sure, now you have a currency that doesn’t rely on trust
…now what? How are you going to spend that currency if you don’t trust anyone? How will you ensure you get what you bought? How will your property get protected? Hell, how do you get others to agree that your crypto is the one they should use?
It’s trust all the way down. Removing it from one small part of the chain isn’t going to fundamentally change things
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.
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?
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.
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.
What does blockchain solve that existing contracts don’t do? Blockchain has takeover possibility
Yea the idea there is that with it being decentralized, it has an unedited history. So if each block added to the chain is a new transaction, you can see previous agreements. Being decentralized also means that it’s public record and everyone can see the contract/agreement/transaction.
There’s a lot of neat stuff that can be done, but as the other guy stated, it’s a solution looking for a problem.
It’s a solution that allows two parties, who are so paranoid they don’t trust banks, let alone one another, to send funds and maintain a record of transactions with one another.
No, it requires a lot more than two parties, because the resulting “funds” from the transaction still have to be valued by everyone else that provide goods and services. So it becomes a social issue if it is to be a currency, and then you just end up re-discovering all the lessons that lead to how currencies already work.
Blockchain / NFTs do not solve proof of ownership. Just ask all the people who had their NFTs or crypto stolen or lost in scams.
In your example, technically title fraud is more difficult because it needs to be done in two places. In reality it becomes far, far easier because you’ve now opened up a gigantic attack surface that you have no control over, and made both systems of verification worth less. If someone manages to compromise either one, there goes your proof of validity. Which one of them is real and which one is fraudulent?
Don’t we already have systems for that? What about the vulnerabilities of blockchain takeover?
Nah. the other commenters are wrong.
They’re super useful.
Its just that anyone who isn’t selling bullshit uses their real name- Merkel trees - which are fundamental to modern software development (git, zfs, nix, nosql).
Merkel is the previous chancelor of Germany, Merkle is a computer scientist ;)
Hash trees are a part of blockchains, but not the entire thing. This is kinda like saying acupuncture isn’t bullshit because needles are useful in real medicine as well.
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.
the way people use NFTs with art are certainly absurd, but even the core technology of NFTs is actually excellent
We’re quite a few years into “the blockchain will revolutionise the world” now and we still don’t really have anything but bitcoin and scams
blockchain as a core technology isn’t user-friendly… it should be hidden, and you’ll never know when it’s doing interesting things. it was never going to revolutionise the world, but that doesn’t invalidate its usefulness in niche situations
… it shouldn’t be used for 95% of the garbage people have built with it - and for NFTs that’s more like 99%
