The European Social Stack
Summary
The European Social Stack advocates open European social platforms and interoperable protocols (Fediverse, Matrix, XMPP) to reduce dependence on monopolistic platforms. It outlines eight common principles (digital autonomy, European tech stack, decentralised networks, European content and infrastructure, wide ownership, diverse business models, strengthening democracy, open source) and three complementary stacks (Private messaging, The Fediverse, The Atmosphere). It also describes joint developments like Eurobridge, distributed identity, content moderation, and multi-protocol integration, aiming for a fully European social ecosystem powered by open standards and open source.
