Sentry nodes

This page is a pointer so operators who land under Nodes still find the full guide.

Primary guide (validators section):
→ Sentry array (oline)

That page covers:

• Why sentries / DoS resistance
• Multi-sentry topology (oline-style arrays)
• private_peer_ids, unconditional_peer_ids, pex = false
• Firewall and checklist
