IRLid — Proof of Personhood

What it does

IRLid lets two people prove they physically met — no app, no accounts, no biometrics required. Two phones. Two QR scans. One cryptographically signed receipt proving co-location within 12 metres at a specific time. ECDSA P-256 via the Web Crypto API. Entirely browser-based. v4: optional bio-metric confirmation (Face ID/fingerprint committed into the signed payload), privacy mode (GPS replaced with SHA-256 hash), trust history scoring. Open source. Free. One developer, UK, spare time.

  There's No Cryptographic Integrity in How We Prove We're Safe2025 · ▲6

  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…

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
