Grant agreement ID: 825585

Funded under:

H2020-EU.2.1.1. – INDUSTRIAL LEADERSHIP – Leadership in enabling and industrial technologies – Information and Communication Technologies (ICT)


HELIOS will design, implement and validate a state-of-the-art, decentralized p2p social media platform which will:

  • Support the ad-hoc creation and management of social graphs within the context and proximity of the user
  • Provide all necessary means and features to ensure the highest level of trust and control is built into the platform (trust by design) which includes among others novel decentralization, content creation and sharing as well as new ways to control monetisation channels and means
  • Ensure the highest level of privacy in line with all the necessary ethical and legal requirements. The concept will be validated indifferent open and closed environments with citizens across a range of demographics and within different contexts.

The HELIOS Modular Architecture

In order to reach the full potential of our vision, we identify the following interconnected activities as the pillars of our design and implementation strategy:

  • Produce an aging-resilient platform
  • Provide a real-life social experience online
  • Facilitate easy content product and delivery
  • Invest in a developer-friendly architecture: keep the platform fresh and interesting
  • Ensure the platform’s growth and resilience

Impact and outcomes

HELIOS envisions an end-to-end solution towards building an engaging peer-to-peer federated social media network, that:

  • Addresses the dynamic nature of human communications in three dimensions: contextual, spatial and temporal
  • Provides all necessary means to ensure the highest level of trust and privacy
  • Facilitates meaningful interactions within an ever-evolving heterogeneous network architecture
  • Democratizes content production, promotion, and monetization
  • Reduces development cost and deployment complexity
