Vitalis Salis - Making Bitcoin Useful Again with Trustless Lending
Timestamps:
(00:16) Introduction and background
(03:00) Joining Babylon
(05:43) The core idea behind Trustless Bitcoin Vaults
(07:28) What “trustless lending” actually means
(12:01) Deep diving into the protocol
(14:38) BitVM and garbled circuits
(18:48) Resources & recommended reading
(21:30) Roadmap and upcoming milestones
(22:22) What's next for the space
(24:55) Advice for engineers building on Bitcoin
Description:
In the sixth episode of Honest Majority, we speak with Vitalis Salis, Head of Engineering at Babylon, about making Bitcoin useful again through trustless lending. 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.
