The Fediverse (ActivityPub Projects)

The Fediverse is a decentralized social networking ecosystem based on the ActivityPub protocol, enabling privacy-conscious communication and community building.

Main Activities:

Decentralized social media, Federated platforms, Platform independence, Censorship resistance, Community-owned infrastructure

The Fediverse refers to a constellation of independent platforms (e.g., Mastodon, PeerTube, Lemmy) that use the ActivityPub protocol to communicate across services. Unlike centralized platforms like Twitter or YouTube, the Fediverse enables users to host their own servers and interact with others freely, with control over moderation and data.

Key Activities:
– Development and maintenance of ActivityPub protocol and compliant platforms

– Empowering users with moderation, hosting, and identity sovereignty
