Open Canvas

Open Canvas is collaborative tool for NFT creation. Basically blockchain implementation of Reddit Place.

Opensource implementation of Reddit place: https://github.com/dynastic/place Webpage: https://canvas.place/

The basic elements of this tool is:

Smartcontract:

• The pixels are solidity mapping( Position(X,Y) ) -> Color(R, G, B)
• It may be a good idea to convert X, Y coordinate to one number. Saves some gas: https://stackoverflow.com/questions/4816322/mapping-x-y-to-single-number-value UPD: Objects are not allowed as mapping keys in Solidity. Another reason to use one number as coordinate.

UI

• Canvas display. Read pixels positions and colors in RGB and display.
• Pixels are submitted in batches. Drawing functional is needed.
• Maybe it is a good idea to have option to convert picture to array of pixels and publish it to the defined coordinate on the canvas.

NFT

• After canvas is finished (on timer) the picture is NFTed to ERC-721
