EFPIX

In a world of growing surveillance, censorship and infrastructure failure, we need protocols that ensure unrestricted communication in the most disconnected and totalitarian environments. EFPIX (Encrypted Flood Protocol for Information eXchange) is a topology-agnostic flood-type relay protocol that also achieves end-to-end encryption, plausible deniability for users, untraceability of messages, spam resistance and other optional features.

Why use EFPIX

Modern messaging platforms, even encrypted ones, depend on centralized infrastructure which makes them vulnerable to:

• Government surveillance or takedown
• Infrastructure loss
• Metadata leaks

EFPIX counters this by never requiring a central server but also hiding not only the message content but also sender's and receiver's identities.

Where to use EFPIX

• Disaster zones where network infrastructure was lost
• Authoritarian Regimes for whistleblowing, journalism and activism where communication is surveilled and cersored
• Space, research, military, or other remote networks where the existence and maintenance of a server is not feasible
• General-purpose privacy focused applications
• Broadcasts like emergency rescue calls, disaster warnings, and news distribution

What is it designed for

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.
