There's No Cryptographic Integrity in How We Prove We're Safe
I built a platform that lets users verify their identity and run a background check—and securely share proof of a clean record without exposing personal details like full name, address, or date of birth. This is something we found missing in all other services: they keep the data locked in their systems and share way too much when you want to prove you're safe. We built a privacy-first solution where you control your data. Use case: You’re a high-profile individual or just privacy-conscious, and want to prove you're safe to meet—say on a dating app—without revealing where you live or your…
What it does
In the maker’s words, at launch
I built a platform that lets users verify their identity and run a background check—and securely share proof of a clean record without exposing personal details like full name, address, or date of birth. This is something we found missing in all other services: they keep the data locked in their systems and share way too much when you want to prove you're safe. We built a privacy-first solution where you control your data. Use case: You’re a high-profile individual or just privacy-conscious, and want to prove you're safe to meet—say on a dating app—without revealing where you live or your full legal name. Our platform gives you a verified badge, backed by real checks, that you can share with others. No oversharing, no centralized profile people can stalk. It’s free now and we’re now integrating with dating apps so users can prove safety and trust without giving away the keys to their identity. Would love feedback, questions, or collaborators. Privacy and user-owned data are the future—and we’re pushing to make that real. www.charisma-check.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…

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
