VPN (Virtual Private Network)

Definition

A VPN encrypts internet traffic and routes it through a server, hiding your IP address from destinations. Unlike Tor, VPN providers see your traffic (but destinations don't see your IP). Post-quantum VPNs use quantum-resistant key exchange protocols.

Technical Explanation

VPN protocols: OpenVPN, WireGuard, IKEv2/IPSec. They establish encrypted tunnels using key exchange (usually ECDH—quantum-vulnerable). Post-quantum VPNs use Kyber or other PQC algorithms for key establishment.

Trust model: VPN provider can see unencrypted traffic. Choose no-log providers carefully. VPNs hide from ISP and destinations; Tor hides from everyone including intermediaries. Different threat models.

SynX Relevance

Use a VPN to hide your real IP from SynX network peers. For maximum privacy, combine with post-quantum VPN protocols. SynX's quantum-resistant transactions combined with network privacy provide comprehensive protection.

Frequently Asked Questions

VPN or Tor for crypto?: Tor: stronger anonymity, no trust in intermediary. VPN: faster, simpler. Both hide your IP from peers.
Are VPNs quantum-safe?: Most use classical key exchange—quantum-vulnerable. Post-quantum VPNs emerging. Check provider specifications.
Can I use both VPN and Tor?: Yes—VPN over Tor or Tor over VPN. Adds complexity but increases anonymity in some threat models.
