A living piece of the internet
A 1,000 × 1,000 canvas — one million pixels — where every pixel can be purchased, coloured, and owned by anyone. The catch: the price doubles every time someone outbids you.
How it works
Open the canvas, zoom in, and click any pixel. You'll see its current price, owner, and color.
Pay the listed price via Stripe. Choose any colour. Ownership transfers to you the moment payment clears.
Anyone can overbid your pixel by paying double. You receive the overbid amount. The buyer takes the pixel.
Pricing model
Each pixel starts at €1. Every time it changes hands, the next purchase price doubles. The formula is simple: €1 × 2ⁿ, where n is the number of times it has been sold.
Price progression
| Sale #1 | €1 | |
| Sale #2 | €2 | |
| Sale #3 | €4 | |
| Sale #4 | €8 | |
| Sale #5 | €16 | |
| Sale #6 | €32 | |
| Sale #7 | €64 | |
| Sale #8 | €128 | |
| …and so on | ×2 each time | |
💡 For buyers
You know exactly what you pay before you commit. The price is always displayed on the pixel tooltip and purchase modal. No hidden fees.
💰 For sellers (previous owners)
When someone overbids your pixel, you receive the amount they paid. If you bought at €4 and someone pays €8, you profit €4 automatically.
Ownership
Ownership transfers happen instantly and atomically. The moment a new buyer pays:
Transparency
Every purchase generates a unique transaction hash — a cryptographic fingerprint computed from the buyer, seller, pixel, price, timestamp, and the previous hash. These hashes form a chain: alter one record and every hash after it breaks.

// Each transaction hash is computed as:

FAQ
Can an admin steal my pixel?
No. Admin actions are fully logged publicly and there is no database policy allowing admins to insert transactions on behalf of users. Every pixel transfer requires a real purchase.
What happens to my money when I'm overbid?
You receive the amount the new buyer paid. The payment goes to you automatically as part of the transaction settlement.
Can I buy multiple pixels at once?
Yes — use Selection Mode on the canvas to select multiple pixels and purchase them all in a single atomic transaction.
Is the pixel ownership forever?
The ownership history is permanent on the ledger. As long as no one overbids you, your pixel stays yours indefinitely.
