I think I will have to make a post to detail it more properly, but I would love to make a co-creation/open innovation coin.
There are many great platforms, like Local Motors, where competitions are hosted to make a new design for an autonomous vehicle capable of performing a certain task, or where companies allow customers to collectively discuss and improve the design or features of a product they deliver.
It would be great to let the submissions of designs, or discussion boards where people share their ideas, use a smeem-like reward system to reward great contributions towards whatever is being co-created. In the case of collective design in a manufacturing / startup competition, that could then translate into company shares. Or in the case of the open innovation of existing products for a company, that company could then accept tokens as payment for their products to reward people who help them improve.
Many opportunities :)
