Changefly ID + Anonymized Identity and Age Verification
Hey HN! I’m Lukas Dickie the founder of Changefly and I’m truly excited to share with you our latest release of Changefly ID with Anonymized Identity & Age Verification. By putting privacy first and using a novel approach to account protection, Changefly ID offers a path to a safer, more secure, and less-intrusive internet for everyone: - Changefly ID for anonymous authentication + ANONYMIZED identity & age verification for services that are required to verify minimum age - Zero-knowledge proofs, secure multi-party computation, temporary unique identifiers - Protects against bot attacks, bot…
In plain words
Changefly ID is an authentication system that verifies user identity and age without exposing personal information. It uses zero-knowledge proofs and secure multi-party computation to let users prove they meet age requirements while keeping their details private. The service is designed for websites and platforms that need age verification but want to reduce data collection, phishing risks, and bot attacks. It targets organizations seeking privacy-first account protection.

Hey HN! I’m Lukas Dickie the founder of Changefly and I’m truly excited to share with you our latest release of Changefly ID with Anonymized Identity & Age Verification. By putting privacy first and using a novel approach to account protection, Changefly ID offers a path to a safer, more secure, and less-intrusive internet for everyone: - Changefly ID for anonymous authentication + ANONYMIZED identity & age verification for services that are required to verify minimum age - Zero-knowledge proofs, secure multi-party computation, temporary unique identifiers - Protects against bot attacks, bot scraping, identity theft, phishing, credential stuffing, online tracking, and other evolving threats Changefly ID + Anonymized Identity & Age Verification is like showing a bartender a “Yes, I’m over 21” hologram badge instead of handing them your driver’s license with your name, address, and birthdate. They get what they need—but none of what they shouldn’t have. We’re just getting started and I’d love to hear what you think, what you’d like to see next, and any feedback you have. https://changefly.com

Anonymous age verification with passkey-powered encryption18d ago · loginwithone.com · ▲45This project has been kicking around in my head since I first heard about the webauthn PRF extension in early 2024. I've slowly chipped away at it since, and finally got things to a shareable state over the summer thanks to a very fun parental leave. Headed back to work tomorrow, so I figure there's no time like the present. tldr: A client-held encryption key derived during passkey authentication encrypts all sensitive user data prior to persistence so that only the user is able to decrypt and reuse that data on their device. This allows short-lived, privacy-preserving age proofs to be…

I built the world's most impractical 1000-pixel display and anyone in the world can draw on it. It draws a single pixel at a time and takes 30-60 minutes to complete a single image. Anyone can participate in the project by voting for the next image to be drawn, and submitting images. https://kilopx.com/

Kitten TTS is an open-source series of tiny and expressive text-to-speech models for on-device applications. We are excited to launch a preview of our smallest model, which is less than 25 MB. This model has 15M parameters. This release supports English text-to-speech applications in eight voices: four male and four female. The model is quantized to int8 + fp16, and it uses onnx for runtime. The model is designed to run literally anywhere eg. raspberry pi, low-end smartphones, wearables, browsers etc. No GPU required! We're releasing this to give early users a sense of the latency and voices…

I was wondering how I can arrange objects along a spherical helix path, and read some articles on it. I ended up learning about parametric equations again, and make this visualization to document what I learned: https://visualrambling.space/moving-objects-in-3d/ feel free to visit and let me know what you think!

For HTML Day 2025 [1], I made a web service that displays the current sky at your approximate location as a CSS gradient. Colours are simulated on-demand using atmospheric absorption and scattering coefficients. Updates every minute, without the use of client-side JavaScript.
