But it's also important to be clear that a complex script large enough to have (critical!) security holes was required to do something as simple and as foundational as multi-sig: the basic building block of all distributed or decentralized protocols. How can possibly expect something more complex to be secure? Bitcoin, on the other hand, builds these core crypto competencies into the base layer, so that scripting can exist purely in the application domain.
