Episode notes
Limit Trust In Persistent Devices
- Avoid over-relying on hardware protections alone because many devices can be exploited over time.
- Prefer solutions that reduce persistent trust in a single device when securing large, long-term holdings.
Multisig Turns Theft Into A Treasure Hunt
- Multisig raises the bar for attackers by decentralizing assets across many locations and devices.
- It converts single-point theft risk into a complex treasure hunt for adversaries.
Treat Descriptors As Private, Not Secret
- Store wallet descriptors and public wallet information redundantly and treat them as private-but-not-secret.
- Use encrypted cloud or multiple secure copies for non-secret derivation data as needed.
