Bithoven: Formal Safety for Expressive Bitcoin Smart Contracts
Researchers from Korea University published “Bithoven: Formal Safety for Expressive Bitcoin Smart Contracts”, introducing a high-level, type-safe language that compiles to native Bitcoin Script while eliminating common script-level vulnerabilities at compile time. Bithoven targets practical on-chain contracts and complements recent advances like BitVM by improving developer safety and expressiveness.

Bithoven: Formal Safety for Expressive Bitcoin Smart Contracts
The rigorous security model of Bitcoin’s UTXO architecture often comes at the cost of developer usability, forcing a reliance on manual stack manipulation that leads to critical financial vulnerabilities like signature malleability, unspendable states and unconstrained execution paths.
