A Fediverse community for open-ended, thought provoking questions
Rules: (interactive)
1) Be nice and; have fun
Doxxing, trolling, sealioning, racism, and toxicity are not welcomed in AskLemmy. Remember what your mother said: if you can't say something nice, don't say anything at all. In addition, the site-wide Lemmy.world terms of service also apply here. Please familiarize yourself with them
2) All posts must end with a '?'
This is sort of like Jeopardy. Please phrase all post titles in the form of a proper question ending with ?
3) No spam
Please do not flood the community with nonsense. Actual suspected spammers will be banned on site. No astroturfing.
4) NSFW is okay, within reason
Just remember to tag posts with either a content warning or a [NSFW] tag. Overtly sexual posts are not allowed, please direct them to either !asklemmyafterdark@lemmy.world or !asklemmynsfw@lemmynsfw.com.
NSFW comments should be restricted to posts tagged [NSFW].
5) This is not a support community.
It is not a place for 'how do I?', type questions.
If you have any questions regarding the site itself or would like to report a community, please direct them to Lemmy.world Support or email info@lemmy.world. For other questions check our partnered communities list, or use the search function.
6) No US Politics.
Please don't post about current US Politics. If you need to do this, try !politicaldiscussion@lemmy.world or !askusa@discuss.online
Reminder: The terms of service apply here too.

You're right on everything else, but this is just no. You never need blockchain.
One just need someone who makes it credible that the hash and timestamp were not tampered with. Even posting the hash on Reddit would do it for most people. Reddit isn't going to commit fraud for some random person. And that random person is probably not able to hack the database undetected.
Recomputing lots of hashes isn't difficult. A blockchain doesn't add any trustworthiness on its own.
I suppose not. Blockchain's a convenient system for this, but some other party 'good enough for court' would do, yes.
I was thinking of software 'standard' enough to centralize it, enough to incentivize has uploading being built into cameras and such as a feature.
