Using the example of a BTC holder taking a stablecoin loan while keeping Bitcoin as collateral, the conversation explores what “trustless” means in practice and how enforceable guarantees can be designed without introducing custody. We discuss Trustless Bitcoin Vaults, how BTC can be locked into UTXOs under predefined conditions, and how supported-chain outcomes can be used to coordinate lending logic. The episode dives into Bitcoin’s constraints, BitVM and off-chain enforcement mechanisms, and the broader implications of extending Bitcoin’s security model beyond passive holding.
