It's a good time to read Life 3.0

Stashu v0.2.0 is live. Main new thing: Verified Peek. The problem was simple. If a file is encrypted, how do you know what you're about to pay for? For text files, sellers can now show a small preview pulled straight from the file. Stashu checks the preview proof before payment, then checks the decrypted file again after unlock. Other formats like PDFs, images, and archives fall back to no preview for now, but still get the post unlock check. Richer previews for those should come later, generated locally. So the buyer gets a simple answer: is what I just unlocked tied to the same file that was shown before I paid? Also in this release: - Blossom server selection + mirroring + download fallback - public seller storefronts - cleaner README and diagrams - a bunch of small UI polish Demo stash:

Been building this for a while, finally ready to share. Sell any file for sats. No account, no platform taking a cut, server never sees your files. Upload a file → set a price in sats → share the link Buyer pays with Lightning or Cashu → file decrypts in their browser. That's it. Built with client-side encryption, Cashu, Lightning, Blossom, and Nostr auth. Would love feedback, reviews, and contributors. Live: stashu.tech Code: github.com/keshav0479/Stashu Try it:
