It offers a versatile framework for real-time messaging, suitable for individual messaging, group chats, and large-scale collaborations. Matrix clients provide a diverse range of options, including web-based applications, desktop clients, and mobile apps, catering to different prefer- ences and needs. These clients support end-to-end encryption and encourage innova- tion through their open-source nature. In this project, Element is chosen as the default client for its robustness and user-friendly interface. It offers seamless messaging and collaboration capabilities with support for end-to-end encryption. Additionally, integrat- ing Matrix with the ELIXIR federated authentication system can benefit life sciences research by creating a secure platform for data exchange and collaboration. Keycloak, an open-source identity and access management solution, can provide the necessary features such as single sign-on, multi-factor authentication, and user management for seamless integration. This integration enhances user experience, simplifies user man- agement, and ensures secure access within the ELIXIR network. Leveraging Key- cloak’s capabilities with Matrix enables a robust and secure communication and collab- oration platform for life sciences research. Keywords: Matrix, Element, Synapse, ELIXIR, Keycloak 1 Matrix Chat Protocol The Matrix chat protocol [1] is an open-source communication protocol that enables secure and decentralized mes- saging across platforms. Users can seamlessly communicate through various chat applications, creating a unified network of channels. Matrix offers a robust framework for real-time messaging, suitable for individual messaging, group chats, and large-scale collaborations. Its decentralized nature ensures privacy and security by avoiding cen- tral server storage. End-to-end encryption allows only intended recipients to decrypt messages. Matrix’s flexibility enables interoperability between different chat applications, allowing communication without platform restrictions. Developers can easily build custom chat applications using Matrix’s open standard and APIs, fostering innovation. The protocol is popular among enterprises, open-source projects, and privacy-conscious individuals. Its versatility, decentralization, and robustness meet modern messaging needs for personal, team, and community communica- tion. Matrix chat protocol offers a cutting-edge and user-centric approach to digital-age communication.
