Episode notes
Beach Wreath Sparked Nick's Bitcoin Journey
- Nick first encountered Bitcoin events at a Beach Wreath where he presented an early SatSale payment button prototype.
- That early awkward talk led him to meet collaborators who shaped his later multisig work.
Script Multisig Leaks Operational Metadata
- Script multisig reveals signer counts and signing patterns, enabling law-enforcement or adversaries to map organizational key holders.
- FROST's single-key appearance prevents that kind of operational deanonymization.
Upgrade Coordinators And Devices For FROST
- Wallet coordinators must implement new FROST message formats and track nonces intelligently to coordinate keygen and signing.
- Ensure hardware rejects reused nonces locally rather than relying solely on the coordinator.
