Age checks vs rage checks
Privacy-preserving age and identity verification via anonymous credentials
New ‘secret pass’ to prove age sparks trust war online
TLDR: A new explainer pitches “anonymous credentials” to prove you’re old enough online without showing your ID. Commenters are split: fans love the privacy math, skeptics fear phone gatekeepers and opaque trust, and cynics say lawmakers will just force real IDs anyway—raising the stakes for online anonymity.
A cryptographer’s big idea to stop the web from turning into an ID checkpoint—“anonymous credentials” that prove you’re old enough without showing your name—just dropped, and the comments went full courtroom drama. In the article, the author explains a privacy-friendly way to pass age checks using math tricks called zero-knowledge proofs (think: “I can prove I’m 18+ without telling you who I am”). Sounds heroic… until the crowd weighs in.
One camp is cheering the explainer as a clear, accessible intro to a future where you can browse without handing over your driver’s license. But the skeptics are louder. One user worries the magic lives on phones we “own but don’t control,” i.e., Apple and Google’s walled gardens. Translation: if your proof lives on your phone, do you actually control it—or do the giants? Another commenter cuts to the chase: trust. Fancy protocols are cool, but ordinary people can’t read crypto code; they want a simple, honest “what am I revealing” screen. Meanwhile, a cynic torches the premise entirely, saying age laws are just a cover to stamp IDs onto every post—and if privacy tech works, lawmakers will just rewrite the rules.
There’s also meta-chaos: someone nitpicks the title change, another flags a broken link, and the thread riffs that if they can’t link right, how are they saving our privacy? The memes write themselves: “Prove you’re 18 without proving you exist,” and “We’re all 13 until proven otherwise.” Hero math vs. Big Tech vs. Big Brother—grab your popcorn.
Key Points
- •New laws in 25 U.S. states and at least a dozen countries require online age verification for accessing certain content.
- •Age-verification checks are extending to major platforms (Facebook, BlueSky, X, Discord) and even Wikipedia under U.K. legislation pressures.
- •Routine ID checks risk linking users’ online activity to government IDs, posing significant privacy concerns.
- •Some laws allow data minimization (discarding verification data), but practices are inconsistent and ad-driven sites may retain identity data.
- •Anonymous credentials, introduced by David Chaum, are presented as a privacy-preserving solution to prove attributes (e.g., age) without revealing identity.
