Dixel

A single NFT canvas where users overwrite the previous edition with price-compounded pixels.

1. There is an universal art canvas with 16x16 pixels that anyone can overwrite
2. Whenever a user overwrites a pixel, the price of the pixel increases by 0.1% (Initial pixel price: 0.001 DIXEL)
3. A new NFT edition with the current canvas state will be minted to the updater (image data is encoded as SVG, 100% on-chain)
4. Total cost that user paid to overwrite pixels goes to:
   • 10% -> all contributors proportional to their contribution count (total pixel count a user has updated so far)
   • 90% -> reserve for refund when the NFT gets burned
5. If a user burn a NFT they own, reserve amount (DIXEL tokens) gets refunded to the user (90% of total minting cost)
