What are CC0 NFTs, and why are they important?

As the Web3 world has largely promoted transparency and openness with code, NFT creators and teams are also opting for the same with art. However, that is just the beginning of the journey, and these nonfungible token creators and communities must realize that.

CC0 can sometimes be portrayed as a logical conclusion where the NFT creators hand over the process of building on their creation to their community and beyond. Some NFT collections have had several derivative projects promoting the culture of the NFT almost as brand extensions. However, declaring a project as CC0 is just the beginning.

NFT project teams and creators who take the CC0 route must actively promote the use of the brand and onboard other creators and projects to build brand extensions to their NFT collections. 

No open-source software project could have scaled without a strong codebase. Similarly, CC0 NFT projects need a strong creator community to spread the word, get inspired by the original nonfungible token collections and make them household brands. This is only possible through the conscious community-building efforts of the NFT project teams.

Therefore, by going down the CC0 route, NFT creators have almost reduced the burden on its nonfungible tokenholders to promote the brand. Instead, they have a more considerable responsibility with their NFT holders to onboard brand, product and art extensions to their nonfungible tokens.

For instance, if a Nike product line chooses to use a Moonbirds image on their shoes, that increases the awareness of Moonbirds within the retail audience, thereby improving the brand outreach. However, these top-tier brand partnerships must be often forged by the NFT project teams.
