To address legal risks, futa sex doll manufacturers have pioneered blockchain-based age verification. A Japanese brand requires buyers to scan government ID and undergo facial recognition to unlock device functions, a technology now being adopted by the lesbian sex doll industry. The EU is legislating that all adult dolls must be equipped with "age locks," requiring traditional mechanical lesbian sex dolls to be equipped with intelligent modules. In this regulatory revolution, futa sex dolls, once marginalized, have become technological pioneers, forcing the entire industry to upgrade their user review systems.
