P2P trading is the Byzantine Generals Problem applied to trust between strangers. Two people who have never met need to exchange value. Neither wants to send first. Classic deadlock. Haveno solves it with 2-of-3 multisig escrow: • Buyer locks funds + security deposit • Seller locks security deposit • Neither can steal — two keys needed to release • Arbitrator holds the 3rd key, intervenes only on dispute This is cryptographic trust. You don't need to trust the counterparty — you trust the math. The game theory enforces honest behaviour: defecting costs your deposit, cooperating gets you the trade. 683 trades, 454 trading partners, 100% feedback. I've never needed an arbitrator for a genuine trade. Skin in the game makes people honest. XMR ↔ EUR. Cash by Mail (EU-wide) + Face-to-face (SW Germany).
