Emittio

Anonymous, decentralized email. Powered by DHT & end-to-end encryption.

Why Emittio?

A next-gen email protocol designed for anonymity, resilience, and full user control.

We're building a mail system that is:

• 🕸️ Decentralized — no central servers, no single point of failure.
• 🔐 End-to-end encrypted — only sender and recipient can read the content.
• 👤 Anonymous — no IDs or accounts
• ⚡️ Efficient — fast delivery

Getting started

Requirements

• Rust (stable) — https://rustup.rs

Build

cd core
cargo build --release

Run

cd core
cargo run --release

🏠 Architecture

In other words, how it works.

Component	Role
Inbox	A public key that acts as a mailbox identifier
Session	A secret seed used to derive inbox keys (no accounts are stored on the network)
Envelope	An encrypted message. Metadata (sender, recipient, time) is also encrypted. Each envelope includes a lookup pointer derived from a shared secret with the recipient.
DHT	Allows to store and find encrypted mails in network
Mixnet	Routes onion-like data through 3 hops (prevents IP correlation) and sends a lot of dummy requests (partially prevents timing correlation)
Nodes	Save encrypted content and forward onion-like messages

Optimization components

Component	Role
Tags	Small encrypted metadata used to optimize lookups
Quorums	Temporary node groups that reduce network-wide scanning

🛣️ Roadmap

1. Alice-Bob cryptography system prototype in Rust
2. Client, Node and MockTransport abstractions
3. Tags, their storage and lookup
4. Application-level transport encryption
5. PeerTable service
6. DHT
7. QUIC and/or TCP transports
8. Mixnet (onion-like routing & dummy requests)
9. Quorums
10. UX & UI prototyping
11. Svelte web client
