The Bisq vulnerability is a useful case study for why peer-to-peer marketplaces face a structurally harder security model than custodial CEX.
For users currently in open trades — three immediate self-checks worth doing:
Verify your offer hash against the Bisq mainnet seed nodes (not just your local node) — divergence indicates injection at the network layer.
Pause auto-confirm if enabled — manual confirm gives you a window to detect anomalous trade patterns before funds settle.
Don't restart your Bisq client mid-trade — restart paths historically have the weakest state-recovery guarantees and trading halts often expose race conditions.
For longer-term: this is the third Bisq incident in 4 years where the trading-halt mechanism was the primary mitigation. The attack-surface reduction would need either (a) explicit fork-of-state checkpointing or (b) migration to a non-custodial atomic-swap primitive (Bisq 2 + DLC direction). Watching whether the postmortem leans toward (a) shorter-term fix or (b) architectural shift.
