EFPIX (Encrypted Flood Protocol for Information eXchange) is a zero-trust, encrypted flood-based relay communication protocol designed for privacy, resilience, and metadata protection. It enables end-to-end encryption, plausible deniability, and untraceable messaging, even in hostile or degraded network environments.
- Topology-Agnostic: Works over any network structure and survives infrastructure loss, censorship, and dynamic topology changes.
- End-to-End Encryption: Protects both content and metadata from unauthorized parties.
- Untraceable messages: Receiver or sender cannot be traced.
- Spam Resistance: Proof-of-Work and deduplication limit flooding abuse.
- Optional Enhancements: HMAC-based signatures, verifiable delay functions (VDF), tagged decryption, dummy traffic, sector-based routing, and more.
- Secure whistleblower and journalist communication
- Activism and censorship-resistant messaging
- Disaster recovery and infrastructure-loss scenarios
- Space/research/military communication where central servers are infeasible
- General-purpose privacy-first peer-to-peer communication
EFPIX is not optimized for high-bandwidth or ultra-low-latency applications
It is best suited for asynchronous, privacy-critical communication such as secure email, file drops, offline messaging, and distributed alerts.
“0% performance, 100% security”: EFPIX prioritizes anonymity and resilience over speed. Choose optional features to balance your needs.
