# Platforms and Companies

#### [ENS (Ethereum Name Service)](https://ens.domains/)

It is a decentralized naming system built on Ethereum that maps human-readable names (like `vitalik.eth`) to digital identities, wallets, and data. In **Prutopia**, ENS is used as the foundation for *usernames*, enabling portable, user-owned identities that can be resolved across apps and shared as simple, consistent handles.

You can read more about usernames [here](/overview/product.md#usernames).

#### [Frutero](https://www.frutero.club/)

A community of builders that creates founders, where talent is transformed into impact. Frutero will enable its community members to incorporate validated learning experiences into their **Prutopia** professional profiles.
