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. This includes using AI responses and summaries.

I'll give you a couple examples of use cases for Blockchain technology that no other technology solves.

As currency:

  • Payment system without content restrictions. You might say "But MasterCard said they're not blocking it", but they could, they could pressure Valve into removing other games, or something similar. Such a thing is impossible in Blockchain, there's no single owner that can impose limits to what you can/can't buy with it.
  • International transactions without restrictions. We talked about how payment processors can stop transactions, banks and governments can do the same and while they use this power less often it's still generally a pain in the ass to move money from one country to another.

As smart contracts:

  • International car ownership deeds. In most countries car ownership has to be registered into the DMV equivalent, this means that moving a car from one country to another is problematic. A smart contract ledger would be an excellent solution to this, countries could use the ledger to transfer ownership and that transfer would be understood by any country that already uses the same ledger as a source of truth, without any of the countries having to trust in the systems built by the other countries.
  • Something similar for phones could also include known stolen IMEI numbers that can be blocked internationally without any regulatory organization needing to trust one another or rely in a centralized controlling agency.
