  • How do you personally use upvotes/downvotes?

    Jump

  • largely agree with this

    • good faith arguments or just good quality comments or posts get upvoted
    • lazy comments or posts get nothing
    • bad faith or unnecessarily combative or ill intensioned comments get downvoted.

    I almost never downvote a post, I'll either block the instance, community, or person instead - I want a good feed

  • Is it completely impossible to do age verification without compromising privacy?

    Jump

  • Right, I understand that perspective, but there is a way to do this with multi-party computation and some other cryptography where no one would have the actual power/be able to see the data/have control. The main issue is it's expensive to run and no one would be incentivized to run it.

  • Not true, there are ways to do this privately with cryptography

  • If anyone is doing actual work trying to solve this please DM me, I'm interested in helping.

  • Ya you could definitely do this way too. There is a standard that google came up with called private state tokens that would allow you to do this in a pretty clean way, if you were cool with using your governments portal.

    Essentially you would login to the govt portal, they would issue you some limited set of tokens (let's say 5) that would expire after 30 days. You would go to an age restricted website and sign up and that would "burn" a token.

    You could use ZK on top of this to make sure that the same email address or some other "nullifier" piece of information was used, to prevent an 18 yo kid from selling their tokens to 17 yos.

  • Good point

  • Is it completely impossible to do age verification without compromising privacy?

  • You definitely can do this with cryptography, it's a really hard problem, but I worked in this space for a number of years, it's possible.

  • I worked in this field for 3 years, a lot of the core parts are written, but there are a few key pieces missing and no one has taken it to real production.

    You can use a passport in pretty much any country and prove you're over a certain age. Here is a demo: https://github.com/dog-18/dog18

    The parts that are missing are primarily around making secure nullifiers, which prevents someone from reusing identities, but also without revealing any private information. We were pursuing research that allowed nullifier generation in MPC where none of the servers or the users knew the "salt" that their identity was hashed with, so no one could recover the original piece of unique data (like their passport number, even if a govt had a hunch about which passports signed up to a service) but it would also prevent them from signing up with multiple accounts. We got our funding cut pretty bad and management was a mess, so I left and that research I think was shut down. This really is the key part to actually make that viable in the real world though. It's maybe a year worth of research and a year worth of production left to make that practical.

  • From personal experience, I went that route (open source non profit) and it ended up being a shit show, i wouldn't assume it's better. I think going the route of just producing things people want to make their life easier is somewhat reasonable. I've been having a bit of a time sorting this out myself.

  • I am learning that people simply do not care

  • I'm also struggling with this, I feel like I lost a piece of myself and I've been grieving a lot of this year with this realization.

  • Absolutely not, we really need a fresh pool of candidates, the Democratic elites need to be fired, all of them.

  • That's a wild and sensationalized statement. I know that there are enough good people to prevent trump from killing tons of civilians. Most people I know in government right now are keeping their heads down and counting the days until the mid terms. Most of the people in the military, even on the right, roll their eyes at a lot of Trump's rhetoric. The sycophant politicians are the only ones that really grovel, and while they can pass laws, and definitely fuck the government up, they don't give the order to pull the trigger.

    In Nazi Germany they had a tight hold on propoganda, we have the internet, it's really hard to do that now.

    In the 70s there was domestic terrorism and bombings all the time and there wasn't mass civilian casualties.

    Is the insane rhetoric turned up right now? Absolutely, but there are many steps between where we are and mass civilian death by the hands of the govt.

    Also, please don't put me in any camp of trusting Trump, that's rude.

  • insurgency can do a lot, especially if the "developed" nation doesn't want to level the place because it's either their place too or will result in many civilian casualties.

    A large part of the US special forces mission is training locals in insurgent/gorilla tactics. Most of the swiss defense posture is training their general population to just be familiar enough with weapons and tactics to wreck havoc on invaders, their standing army and armaments are really small.

  • Why is blocking so common nowadays?

    Jump

  • Agree with this. I don't shout my opinion and then block, but I definitely block a lot of users who just have really intense views they want to share, and communities I have no interest in, and over the last couple years my curated space is a reasonable mix of memes, news, and not to extreme of views, and it's nice.
