**Littlefish** are the actors of the system. They are individuals who want to enable and enact change in the world. They come together on the Littlefish Platform to form colonies.

Colonies perform real-world activities.

- A digital community collaborating towards social/environmental impact.
- A DAO creating blockchain solutions for a use case.
- A business announcing/developing/producing a new product.
- A charity organizing a new campaign to build houses for those in need.
These activities are documented in whatever way colony members choose - video, image, recordings, tweets, Instagram, … Collected multimedia is then published as NFTs called **Actions**.
Actions are the [[13- The Attributes of Action#Proof of Activity PoA|**Proof of Activity**]] (PoA). They contain information showing that something has been done to impact the world. [[7- Why Purchase Actions|Actions can be sold]] to generate funding.
