Changelog - v1.1.4 (2025-08-21)

Fixed

• Peering flood that causes your node to go offline

Code Changes

• Implemented STUN functionality with a workaround for The Great Firewall (fallback to HTTP IP check)
• Above is skippable by manually setting your public facing IP4 via env PUBLIC_UDP_IPV4=
• Implemented ANR (Amadeus Node Records)
• All new peering requests are met with a challenge

📜 Technical Context

This release addresses a DDOS attack where a malicious agent can force a node to interact with non-existent peers, taxing resources from the node that it goes offline.

Thanks

@xdd3384 for help debugging and rp_filter setting which should prevent spoofed UDP src addr
