How is the blockchain different from a read only ( write only once to be specific) DB that follows ACID?

[–] [email protected] 3 points 9 months ago (1 children)

Blockchains add cryptographic signing and limit actions based on those signatures.

To you maybe. Maybe other lemmings reading this understand them.

[–] [email protected] 2 points 9 months ago (1 children)

They mean nothing in the sense its nothing you cant do with DBs, so like I said, big words that mean nothing

[–] [email protected] -1 points 9 months ago (1 children)

Cryptography - means that only you can make changes. No database administrator. No hacker. No-one but you.

Limited actions - means the changes you make must follow rules that cannot be altered by anyone.

Both impossible to implement on a normal DB, which is why bitcoin was revolutionary.

  1. thats not what cryptography means, and is a huge fucking downside especially for banking which us centrally controlled

  2. It's called triggers, user roles etc, once again you dont want this to be unalterabale for banking because what if regulations change...

Only thing bitcoin revolutionized was the speed with which scammers can dupe people out of their money.

[–] [email protected] -1 points 9 months ago (1 children)

thats not what cryptography means,

You didn't even know what "those big words" meant a second ago.

downside especially for banking which is centrally controlled

Banking doesn't need to be centrally controlled. It only has been for the past few hundred years.

  1. It's called triggers, user roles etc,

Why pay and trust a 3rd party control those?

what if regulations change...

You update the smart contracts

The only thing bitcoin revolutionized was the speed with which scammers can dupe people out of their money.

Almost true. Scams are not the only thing revolutionized.

[–] [email protected] 2 points 9 months ago (1 children)

Dude, my name literally contains "coding" you made the assumption I didn't understand it...

Yeah banking needs to be controlled because what if something goes wrong, you can't be this dense, stolen credit cards, stolen identity wring transaction, what if the validators disagree what is the truth ala bitcoin split?

Blockchain is woefully inadequate to manage finances...

[–] [email protected] 0 points 9 months ago (1 children)

you made the assumption I didn't understand it...

No. You admitted those words mean nothing to you.

what if something goes wrong

You plan for each eventually and ensure all responsibilities are understood.

stolen credit cards, stolen identity wring transaction,

Multisignature, limit controlled wallets

what if the validators disagree what is the truth ala bitcoin split?

Wait for a few blocks before assuming your transaction is confirmed. Don't be dishonest during a fork event.

Blockchain is woefully inadequate to manage finances...

The general public is woefully uneducated and unsupported for blockchain managed finances, but the technology is fine.

[–] [email protected] 2 points 9 months ago* (last edited 9 months ago) (1 children)

I have literally explained to you what I meant, there is nothing to admit, lmao.

This is the issue with cryptobros you just think you are so much smarter than everyone else, and everyone else must be stupid and just not understand how crypto works.

Meanwhile you cant even see the huge flaws with the technology, you think " just wait and don't be dishonest" while there is a disagreement and unrecoverable split in the network is a viable solution... fucking hell that's such a childish take

[–] [email protected] 0 points 9 months ago

When was last time a fork caused an unforseen problem in a popular blockchain?

There are plenty of things about blockchain technology you could have mentioned that are not yet perfect (privacy, scalability, accessibility, governance, regulation, interoperability etc.) but the best attack you have is that cryptography is meaningless.

[–] [email protected] -1 points 9 months ago

They were saying what it meant in this context

Meaning, in a DB, the admin could change roles and modify anything.

Database triggers can have bugs, and we generally don't let third parties log into the database directly because it's a huge attack surface

In blockchain, without a key you're cryptographically locked out. The only way around that is if the network as a whole changes their code to a version that allows something like that

It's just a ledger where every entry is signed by a private key. That's a fantastic structure for certain specific use cases...

[–] [email protected] -1 points 9 months ago

Replication and verifiable timestamps, which you can add to regular databases too BTW

[–] [email protected] -1 points 9 months ago (1 children)

How can you trust that the database is really append only? Blockchain provides a way to verify the state of the database and the ordering of the transactions. Beyond that, not much benefit to be had. However, for certain situations, that is a very big benefit!

Sure! So some students of mine were working on a multiplayer video game that was started by a different group of students the previous semester. The first group of students made a design choice that, to over-simplify, basically tracked achievements and milestones on the client side and then synchronized those achievements to the server. Players could cheat the system by sending malicious packets of achievements to the server. Some achievements could only be completed by a single person in the game, so this was a big problem for the 2nd group of students to overcome. Faced with the choice of rearchitecting the game to be more authoritative on the server and less resilient to frequent disconnections, which affected some aspects of the game, or creating a logical and verifiable sequence of in-game events on the server side. The students went with the latter, and implemented a Lamport clock using a blockchain to verify the authenticity of the events, and prevent a rogue student from updating the game later to give themself a bonus. Basically, along with needing an authoritative sequence of events that is protected from user interference, it also needed to be protected from developer interference.

It was kinda similar to that situation a few years back of the EVE online developers playing the game and giving their guild members certain bonuses and special in-game items. The solution there was to fire the malicious developers, but I can't exactly fire an entire class of students from an educational project.

EDIT: What seems to be the problem here? I was asked to name a situation where a blockchain would be useful and I did? It's a computer data structure, there are pros and cons that are context dependent like any other data structure. It I so weird to me to receive downvotes because of the politics surrounding a data structure.

[–] [email protected] 2 points 9 months ago (1 children)

To your edit; it was a great example, but if you say anything positive about blockchain (or Apple, or capitalism, etc) you’ll likely be heavily downvoted on Lemmy.

[–] [email protected] 4 points 9 months ago (1 children)

Yeah, I think that seems to be the case here. It just feels to weird me to have a politicized data structure.

Ha!

But yeah, like others have said in this post, it had a bad light cast on it due to the jpg and gif NFTs. Folks started to realize: "wait... this token just contains a link to a web server hosting a jpg file??"

Well, yes. But also the rights.

"The heck you mean 'the rights'??"

I mean, your Drunk Monkey in Teal Color Theme artwork is yours to use, you've purchased the license in the form of an NFT.

"But it's just a link that anyone could just copy!"

Well, that would be stealing.

So NFTs in that regard are like any movie or TV show, or video game you rent or purchase. That utility may or may not seem to have any value to any one person, but it is a utility, and a pretty cool one if you ask me. But the usage, its implementation, is what matters. Whatever that usage requirement is for the individual or business, blockchain will do it well. Even if it is used to license junk.
