SlumberBloom is a small garden game that only grows when you leave your phone alone.

Description and use

SlumberBloom is a local‑first garden game that uses SHA‑256 and Merkle proofs to verify that users left their phone for a period, rewarding them without tokens or server trust.

Problem

Users want a game that rewards them for not using their phone, but existing games rely on tokens, wallets, or server trust.

Outcome

The prototype demonstrates a fully local, verifiable game loop that rewards users for not using their phone, with cryptographic proof and no external server trust.

Workflow

• Tap "Tuck In" to start the night
• Leave phone for ≥30 min and ≤10 h
• Wake up and app mints a Night Block (SHA‑256 hash)
• Claim the block as Morning Dew
• Settle it at Dawn to become Bloom
• Use "Light the Lantern" to re‑check any block with a Merkle proof in the browser

Evidence

Turn sleep away‑time into a verifiable garden — SHA‑256 Night Blocks, RFC‑6962 Merkle proofs, Charter‑supply math.

Source

Your hours of patience are verifiable, and a “Light the Lantern” button re‑checks any block with a Merkle proof, right in your browser.

No tokens, no wallets. Just your time, made beautiful.
