In response to RFP for Developing a decentralized painting canvas on Cartesi Rollups

New proposal

Decentralized Painting Canvas on Cartesi Rollups

A collective painting DApp with option to generate NFTs

Project Description

In response to RFP

For the purpose of the project we would like to propose implementation of Fabric.js, one of the most popular JavaScript libraries for HTML5 Canvas.

How you will use Cartesi, specifically?

The back-end application will be running on the Cartesi Machine. For the specific implementation we are envisioning Node.js server that is executing inputs from the React.js front-end application. Both front-end and back-end will be utilising Fabric.js as a HTML Canvas library. The goal is to demonstrate the ability to have a decentralized use of open software components / libraries like Fabric.js. All states of the collective canvas will be submitted to the blockchain, in addition the back-end application will generate snapshot images (PNG/JPG) of each state of the collective drawing (everyone’s contributions) and save them as NFTs.

Here is a video demonstrating the basic concept of our proposal
.

This is just a demonstration of the front-end and back-end use, without the rollups implementation. In our demo, both front-end and back-end are using the same canvas library. The back-end is receiving input from the front-end on drawing save and store incremental canvas on the server together with a snapshot image that represents the current state.

Great proposal and would like to see it come through!

Only comment is that the CGP is now funded with USDC instead of BUSD due to regulatory complications.

Here is USDC ERC-20 address:
