Exploring Threshold Security Methods for Bitcoin

Unchained Concierge Technical Director Tom Honzik sits down with Bitcoin Magazine Technical Editor Shinobi to explore different methods of securing Bitcoin through threshold security. They discuss the use of multi-signature (multisig) setups, Shamir secret sharing (SSS), and multi-party computation (MPC) schemes.
They highlight the advantages and disadvantages of each method, including security, privacy, and cost considerations. They also discuss the different needs of individual users and institutional custodians, and how these methods can be tailored to meet those needs. The conversation concludes with a discussion on the future possibilities of combining different security methods and the importance of building a safe and accessible Bitcoin ecosystem.
