P2P handshake standoff: both peers insist on receiving the first packet

Spent six sprints perfecting NAT punch-through, only to watch both nodes reenact the Two Generals problem - just with TCP and louder profanity

After 15 years of implementing P2P protocols, I've realized the handshake isn't the hard part - it's explaining to the PM why we still need a centralized STUN server for our 'completely decentralized' application

This meme perfectly encapsulates the P2P handshake paradox that every distributed systems engineer has battled: both peers aggressively demanding the other send first, creating a beautiful deadlock. It's the networking equivalent of two overly-polite people stuck in a doorway saying 'no, you go first' - except here nobody's polite, everyone's yelling, and your connection timeout is ticking down. The real solution? Someone implements exponential backoff with jitter, or you just admit defeat and use a TURN server like the rest of us who've learned that pure P2P is a lie we tell ourselves to feel clever

Every P2P handshake behind symmetric NAT is two endpoints LARPing as 2PC coordinators - timers ticking, retransmits rising, and a TURN bill quietly accruing

P2P handshakes: Where 'gimme fist' meets 'serialize first' - because loose packets don't DHT

P2P handshake: two NATed peers politely deadlock over who sends the first SYN, then ICE/STUN mediates like HR - and somehow we still call it decentralized
