SentinelNet is a decentralized, end-to-end encrypted communication and data-sharing platform designed for maximum privacy and resilience against censorship and surveillance. It leverages a federated or peer-to-peer network architecture, allowing users to host their own nodes or connect to trusted community nodes, making it resistant to central shutdowns, inspired by the challenges of online safety acts and the idea of becoming your own ISP. Advanced on-device AI models (leveraging large context windows like Claude Sonnet 4) are used for private content summarization, intelligent routing, and user-defined content filtering, ensuring sensitive data never leaves the user’s control and mitigating risks like remote conversation detection. The platform aims to provide a secure digital haven for individuals and organizations concerned about data privacy and communication freedom.
