Nexus Marketplace Guide

Technical profile of the Tor-native gateway as a marketplace system — infrastructure parameters only

Last Updated: Uptime 90d 99.98%

Platform profile

Nexus Market operates as a Tor-only escrow gateway. Access is exclusively via v3 onion addresses over Tor circuits. Accounts are pseudonymous, sessions expire on inactivity, and dispute mediation is key-based rather than ticket-based. This guide documents public infrastructure parameters for defensive research.

Escrow and Multi-Sig

Standard settlement uses 2-of-3 Multi-Sig. The buyer, the vendor, and a gateway arbiter each hold one key. Release requires two signatures, refund requires two signatures, and arbitration requires the arbiter plus one counterparty. This removes single-key custody. Background on onion services is available at Tor Project.

Operational guarantees

  • Tor-only — no clearnet credential surface
  • New deposit context per order — strict address hygiene
  • Mediated disputes — majority-signature resolution
  • Redundant gateways — no single point of entry

How to proceed

Verify a gateway under Mirrors, settle per Crypto, and review OPSEC before any session.
