Pre-warmed QUIC/TCP Connections — Ethereum Networking Privacy Map

Description

Maintaining persistent, multiplexed connections to eliminate handshake overhead on the critical path of attestation broadcast.

Target	Type	Note
P1	benefits	Eliminates TLS/QUIC handshake latency from propagation path.
P6	benefits	Crucial for meeting the 2-second slot time targets.
P2	hurts	Maintaining many open stateful connections consumes memory.
P7	hurts	Requires careful stream management and peer discovery tuning.
P3	hurts	Proactive connection to subnets leaks validator intent to peers.
A2	enables	Pre-warmed connections are required to meet OHTTP latency targets.
