What is a Reticulum Link?

A link is an abstract encrypted channel between two nodes that provides forward secrecy, initiator anonymity, and reliable delivery, independent of specific IP addresses.

What are the standard link states?

Links transition through five states: PENDING (request sent), HANDSHAKE (keys deriving), ACTIVE (operational), STALE (idle), and CLOSED (terminated).

How does the Reticulum handshake ensure security?

It uses a three-packet exchange involving X25519 ephemeral keys for ECDH shared secret derivation and Ed25519 signatures to prove destination identity.

How does the keep-alive mechanism work?

Links send a ~20-byte keep-alive packet every 360 seconds when idle, moving to a STALE state after 720 seconds before timing out to conserve bandwidth.

Security & Testing

Provides expert knowledge for implementing and managing Reticulum's encrypted, anonymous communication links with forward secrecy.

About

This skill equips Claude with specialized technical knowledge of the Reticulum Network Stack's link system, allowing it to assist in the development and debugging of secure communication channels. It covers the entire lifecycle of a link, including the three-packet handshake, X25519 ECDH key exchange, and state management from initiation to closure. Developers can leverage this skill to implement reliable delivery, calculate MTU/MDU overhead, manage keep-alive intervals, and ensure initiator anonymity within decentralized or low-bandwidth networks.

Key Features

Comprehensive mapping of link state transitions and timeout logic.
Cryptographic implementation details for X25519, Ed25519, and AES-256-CBC.
Deep documentation on the 3-packet handshake protocol (Link Request, Proof, RTT).
Calculations for Maximum Data Unit (MDU) and bandwidth costs.
Guidance on forward secrecy and initiator anonymity implementation.
0 GitHub stars

Use Cases

Optimizing link state management and keep-alive overhead for efficiency.
Troubleshooting network timeouts and RTT measurement issues in low-bandwidth environments.
Implementing secure link establishment in decentralized Reticulum applications.
