Episode notes
Wrench Attacks Are A Structural Self Custody Problem
- Wrench attacks expose a structural weakness: self-custody collapses when something more important than Bitcoin is threatened.
- Jonathan Pollock argues coercive physical threats bypass key-based protections because everyone has priorities they'll choose over Bitcoin.
Don't Rely On Duress Pins Or Decoys
- Avoid relying on deception-based mitigations like duress pins or decoy wallets because they often just relocate access or escalate attacker violence.
- Design systems assuming attacker knows your setup and victim is compliant, then add technical barriers that still protect funds.
Seedless Architecture Reduces Instant Key Compromise
- Seed phrases are a recovery convenience that instantly export private key material and therefore create a single-point compromise.
- BitKey's seedless design keeps the private key inside hardware and uses transactions plus multisig to enable safer, restricted exits.
