Episode notes
Recover Or Rotate Shares Without Seeds
- Frost enables restoring or rotating shares without entering seed words by using other devices to reconstruct a lost share.
- That cryptography can restore a broken device by interacting with remaining devices directly.
Geographic Distribution Replaces PINs
- Frostsnap intentionally omits PINs and secure-element–centric UX because multisig uses geographic distribution as authentication.
- They prioritize inconvenient spending paths for cold storage to reduce quick coercion or theft.
Encrypt Device Shares And Use Phone Auth
- Encrypt each device's secret share and store the decryption key on your phone so a single found device is useless.
- Require the phone unlock to release the decryption key and start signing sessions.
