Bitcoin’s ‘last resort’ quantum-safe solution just got 79% cheaper: StarkWare

StarkWare reported that its quantum-safe Bitcoin recovery mechanism can now be implemented at roughly 79% lower cost, reducing the burden of moving coins from vulnerable address types to post-quantum-secure ones. The approach uses STARK-based proofs and would serve as a potential last-resort defense if quantum computers threaten Bitcoin’s cryptography. The cost reduction improves practical feasibility, but adoption would still require Bitcoin protocol changes, user coordination, and confirmation that the technology is secure and scalable.
