Catalyzing BTCFi with Trustless Bitcoin Vault
summary
Babylon Labs describes a concrete system: trustless Bitcoin vaults implemented as Taproot UTXO scripts that use bitvm for optimistic verification, enabling native BTC to be locked without wrapping or bridges. It already secures Babylon Genesis via native staking and reports just under $7 billion of BTC staked, making it the second‑largest native Bitcoin protocol after Bitcoin itself. Design details include on‑chain redemption and scripted liquidation paths for lending (BTC collateral → USDC loans) with slashing enforced by vault logic.
