I propose a new type of token, CFT - Collaborative Fungible Token
It consists of a token that is created between different members of the community, each one will contribute a grain of sand or portion of the token and together a whole will be formed.
There are 2 types of owners:
-
The owner or owners of the CFT, who will have the power to decide what to do with it, for example put it up for sale or exchange it.
-
The monetary owners of the pixels/percentage/shares that will be able to exchange them individually and receive the royalties that correspond to them.
I give you an example based on the mural r/place of Reddit, imagine a mural of 1000 by 1000 pixels, each user or address will have permission to paint one or more pixels in one color, once they are all painted the mural or Token will be complete and it will belong to all the users who participated in its creation, each user will own a percentage that will depend on their involvement, that is, if you painted 2 pixels, you own twice as much as whoever painted 1.
I am currently working on a simple demo version of how to form a CFT, it is deployed on the BSC Testnet.
If you’re interested in me being on other testnets, let me know.
TokenizedPixel
I present to you the draft of a CFT, I have treated the portions of the CFT as pixels, I hope you find it interesting and help me improve it
