Nox: A Sphinx Mixnet for Anonymous Blockchain Transaction Relay

Jayendra Madaram, Reze Sakiv · Hisoka IO

A Sphinx mix network co-designed with an anonymous transaction relay layer for Ethereum. Exit nodes submit transactions on behalf of anonymous senders through a zero-knowledge gas payment circuit. Reed-Solomon forward error correction on SURB response channels raises multi-fragment delivery from 31% to 98% at 10% packet loss. Per-hop Sphinx processing takes 58.6 μs on the classical NIKE path, 2.5× faster than Katzenpost.
