Sliver Exchange: Micro-Economy Marketplace App Prototype

Sliver Exchange is a working, clickable app prototype for a new kind of marketplace: households sell spare computing power from idle smart-home electronics and license their personal data models by the query. Use it to pitch the idea, test it with users or start your own build.

Everything runs in a single HTML file. Open it in any browser, on desktop or phone, with no install and no coding needed.

Four interactive screens

• Earn: a live meter that counts earnings down to fractions of a cent, an hourly earnings chart, and six example devices with on/off switches, capacity sliders, allowed hours and A–G efficiency ratings.
• Market: a live compute spot price with a 24-hour chart, an order book, buyer jobs your devices can accept, and buy orders that fill over time.
• Data licenses: offers you can accept, counter or decline, licenses you can revoke, a privacy budget per model, and a form for listing new licenses.
• Ledger: every micro-transaction, with automatic batch payouts.

Made to customise

• Rebrand in minutes: change the name, currency, city, fee and payout settings in one clearly commented config block.
• Light and dark mode, and a layout that works on phones and desktops.
• Realistic pricing per TFLOP·h, electricity costs and privacy settings, with fictional example buyers.
• Simulation speed of 1×, 10× or 60× for live demos.

What you get

• index.html: the complete app
