Show HN: Krowdovi – Video-based indoor navigation on a DePIN creator economy

Crypto paywall for indoor directions? Devs cheer, patients rage

TLDR: Krowdovi launched video-guided indoor navigation that pays creators via a crypto token, burning most tokens and sharing the rest. The community split: some praised the innovation, while critics balked at a paywall for hospital directions and asked basic usability questions, suggesting simple QR videos instead.

Krowdovi showed off a wild idea: first‑person “walk with me” videos to guide you through hospitals, airports, and malls, powered by a creator economy and a crypto token that users burn to unlock navigation. The crowd loved the clever touches—motion‑controlled playback that pauses when you stop, AI‑translated overlays, and a drag‑and‑drop editor—but then the comments lit up like a baggage carousel. One camp shouted “innovation!” with 31337Logic dropping a heart‑emoji level “great work.” Another camp asked the obvious: m00dy wondered, “after I scan a QR code… how does it know where I’m going?” Meanwhile, utopiah pulled the DIY fire alarm: skip the token stuff, just use PeerTube, print a QR, and call it a day. The biggest blowback? Accessibility. usefulposter painted a hospital panic scene: scan a code, get a Cloudflare video… then hit a crypto paywall. That clash—“help people find their way” vs “make creators money”—became the day’s drama. Krowdovi leans on “DePIN” (a fancy way to say crypto for real‑world infrastructure) with burn‑and‑mint tokenomics (75% burned, 25% pays creators), plus reputation tiers for earnings. But the meme energy came from people imagining treadmill‑hacking the motion control and roasting the idea of burning tokens while burning patience in a maze of corridors.

Key Points

  • Krowdovi is a video-based indoor navigation platform using a DePIN model to pay creators for guidance content.
  • Users burn tokens to obtain navigation credits; 75% of tokens are burned and 25% go to a weekly remint pool capped at 500K.
  • A reputation system assigns Bronze–Diamond tiers with multipliers (0.5x–2.5x) based on freshness, completion rate, ratings, accessibility, and no-bounce.
  • The tech stack includes Next.js, React, Express, Prisma, PostgreSQL, Redis, Solana (Anchor, SPL Token), Cloudflare Stream (HLS), hls.js, and wallet/JWT auth.
  • Navigation features include motion-controlled playback via DeviceMotion API, multi-language overlays, NFC/QR/App Clip access, and accessibility options.
