- Change p2p-max-nodes-per-host from 100 to 2 to prevent connection exhaustion attacks (fixes XPRNetwork#17) - Add get_p2p_nodes.sh script to discover and test P2P peers by latency - Add peers.txt with 16 verified active mainnet P2P peers (Jan 2026) This addresses the security vulnerability where a malicious node could occupy all incoming connections by setting p2p-max-nodes-per-host too high.

With
p2p-max-nodes-per-host = 100andmax-clients = 100, a malicious node could occupy all incoming connections from a single host, preventing legitimate peers from connecting. This change limits connections per host to 2, which is the recommended setting.Files Changed
