Nexus darknet market core architecture
Zero-Trust Model
No centralized hot wallets → Per-order multisig escrow → PGP-signed dispute resolution → No KYC → No logs → No metadata
- Stateless session architecture
- Ephemeral Tor endpoints
- Distributed onion service keys
Technology Stack
- PHP 8.2+ hardened
- PostgreSQL multisig
- Multi-region CDN Tor
- OpenPGP.js client-side
Scale Architecture
15K+ listings → 99.8% uptime → Multi-region onion mirrors → Horizontal scaling → DDoS-resistant Tor endpoints
Phishing-proof authentication protocol
PGP 2FA Flow
- Username + Password
- Server → PGP nonce challenge
- Client → Sign nonce (private key)
- Server → Verify signature (public key)
- Session → 24h PGP token
Key Specifications
- 4096-bit RSA main key
- 4096-bit subkey (signing)
- 25+ char passphrase mandatory
- Public key → Profile verification
- Subkey rotation → Yearly
Client-Side Crypto
OpenPGP.js → All signing happens in browser → No private key transmission → Server verifies signature only
- Zero-knowledge proof auth
- No passphrase storage
- Ephemeral session keys
Phishing Immunity
Phishers cannot replay PGP signatures → Each nonce unique → Time-bound → Server-side verification → Private key stays client-side
Per-order multisig escrow architecture
2-of-3 Multisig
- Key 1: Buyer deposit
- Key 2: Vendor confirmation
- Key 3: Market arbitration
- Funds locked until 2/3 sign
No Hot Wallet Risk
No single point of failure → Individual order escrows → No centralized treasury → Hack-proof by design
Dispute Resolution
PGP-signed evidence → Market arbiter → 2/3 multisig release → Final and binding → No chargebacks
Distributed onion service infrastructure
v3 Onion Specs
56-character ed25519 onion addresses
- Ed25519 key derivation
- 56-char .onion v3 format
- Introduction points rotation
- HSv3 descriptor signing
Endpoint Rotation
Weekly onion rotation → DDoS mitigation → Denial-of-service protection → Load distribution → Geographic redundancy
- PGP fingerprint constant
- Backend infrastructure identical
- Check live mirrors
Nexus Market development timeline
2023: AlphaBay Void
AlphaBay shutdown → White House Market retirement → Power vacuum → BTC markets compromised → XMR-only gap identified
2024 Q1: Nexus Launch
Zero-trust architecture → PGP 2FA → Wallet-less escrow → Tor v3 endpoints → 5K initial listings → Rapid vendor migration
2025: Scale Phase
15K+ listings → Multi-region mirrors → 99.8% uptime → PGP vendor verification → Multisig escrow maturity
2026: Market Leader
Post-AlphaBay dominant → XMR standard → Zero-trust reference → Phishing clone proliferation → Hub verification essential
