Ask HN: What Did You Work On? (June 2026)

• lyfeninja 2mo ago
  Just soft launched BlkSeal, a modern content integrity platform. It lets people, apps, and AI agents sign any digital content so anyone can verify it hasn't been modified after it was created. Think provenance and tamper detection, but with a different trust model than traditional digital signatures, including native revocation. The underlying tech is actually very cool. Just put it out there, so now I'm in the fun/scary phase of seeing if anyone besides me actually wants it. Either way, I've learned a ton building it, and it's been one of the most rewarding side projects I've ever turned into a startup. Website: https://lyfe.ninja/ https://lyfe.ninja/
