No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

That's a lot of words to say nothing. Like, you literally aren't saying anything of substance.
All of that is word salad. Blockchain is 100% redundant technology that uses obscene amounts of electricity. Why do I need a network of computers around the globe to make sure a contract and checks get signed? Why does it require a global network of computers constantly refreshing themselves and checking for inconsistencies to implement new business? If the smartest minds on Earth actually can't come up with a use case, then it's trash.
Grifters love it.
Blockchains don't inherently need obscene amount of erlectriciy
Proof of work mechanism does. There's lots of other consensus mechanism that don't.
Forward signed, immutable ledger - a dataset that is written and logged at time of write and validated using cryptographic signatures of the creator of that data and the node of the network responsible for the data. public systems use incentive systems to ensure unbiased writes, private systems work more like your typical app server.
neutral consensus - this is the p2p aspect, this is a bunch of unrelated actors promising to work toward an unrelated goal, in public systems this is done via some form of game theory, in private systems orgs working together have contract law and are more interested in the the controlled writing.
How it can take a lot of forms. Most people are just familiar with what the general public refers to as cryptocurrency. These are ledgers managed on p2p networks with the aforementioned game theory based consensus system. However ledgers are not required to do this, a ledger and even a blockchain can work without fees or even energy wasting miners, in these cases its usually the cryptographic write and channel messaging they want (some of these are a step up from AWS's messaging stack).
Ledgers like this are used in many ways and used in large orgs around the world, what the public is angry at and what the technology is are very different things.
I hope I have "unsaladed things" for you
Blockchains come in many forms, the ones you are thinking of are what are called Proof of Work chains, these uses a kind of cryptographic race to secure thier data and use a TON of waste energy as a result. Def not a fan either.
The growing popularity and interest in chains is around forms of Proof Of Stake, these use other internal protocol mechanisms to secure the network and work to run the cryptographic functions as efficiently as possible. Unsurprisingly the fastest blockchains are proof of stake and power wise are similar to traditional applications in utilization.
You don't need any of these networks if you don't want to use them, fundamentally, they arent even networks, they are cryptographic messaging systems. How the data is sent and processed is incidental, you could work out a bitcoin block on pen and paper if you wanted. This concept has extended to a cryptographic tool called Zero Knowledge Proofs, these will be part of next generation identity verification systems and is a fundamental of the W3C standard around DiD, the whole point is for disconnected attestation.
Maybe this is my “too old for this shit” moment, but this all just sounds like convoluted non-sense that’s never going to go anywhere. We still have SMS and ATMs that run XP.
surprisingly small hardware is needed to sign a message. though I do agree that we are still a bit early for workable end-user use cases. People really dont care what the database or app server is, they just want it to work and raw dogging some public node is just a bit much for people, i dont blame them.
more packaged solutions are under development, these will be more like a proper application with the differences of a chain being abstracted by the provider
things like sms, what if i told you SMS would be fine with this, so would smoke signals
I think the problem I have with it is the online enthusiasm for it is acting like it’s already going to change my life yet it’s been more than a decade and no one has shown tangible and understandable utility, just marketing bs and grifting.
But we're still early lol
Yea I’ve been hearing that for a decade. Aside from missing out on bitcoin at $300, I’m still waiting. 🤷♂️
i think there was a lot of hope among some at the public systems, no clue if it will bear out, the tech however is a viable PKI distro strategy that has been proven to work already in multiple large orgs in different forms. We don't talk about how expensive or difficult it is to control your own PKI. Its one of the key reasons why you have to yield so much data and control to providers.
I could go on a long rant about what the internet was built to be vs what "big tech" has perverted it into, using p2p technologies to do it then saying "i dont see what the point is for people to have versions of this for themselves rather than it being only in the hands of big corps controlled by share holders" but thats about as far as Ill go.
as for private systems, this stuff is already starting to rule your world. distributed PKI systems in enterprise require expensive and technically onerous trust ceremonies for each cross system connection. you also require functioning cert trees from root to tip in order to validate anything in most of these systems (tools like pgp are the exception rather than the rule sadly). These systems are expensive to operate and add another single point of attack to the system. There are already chains doing internal asset management at companies, and its quite likely that any DiD standard that becomes a gov ID will be on a ledger network not that it should matter to end users.
the biggest push with the latest wave of the tech is to stop trying to sell to people, sell to enterprise, the usecases are more solid and don't require strange economic games to function.
You will be using blockchain tech, but if its deployed right. You will never know. Do you know or care what app server or db your provider uses? of course not.
