Factflew
Zero-data file certification via local Web Crypto & Polygon
What it does
Factflew is a file certification service on Polygon built around an "Unknow Your Customer" (UYC) architecture — anonymous timestamps, zero identity collection. SHA-256 hashes are computed locally via the Web Crypto API, so files never leave your device. Certificates are issued instantly through a PWA, with no names, emails, or phone numbers; device auth runs entirely on an FF-code system.
Децентрализованная регистрация цифровых следов в блокчейне Polygon. SHA-256 хэш файла записывается навсегда.
Публичный блокчейн открыт для всех. Любой может проверить запись без посредников Сервис фиксирует факты, не удостоверяет личность. Честность — основаfrom factflew.io

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
