"There was no software to support the rigorous engineering of complex systems from the ground up — from the verification and validation of simple systems (subsystems/components) with explicit assumptions, up to more complex, stochastic, dynamically networked systems with emergent properties in line with specified requirements. This full range of capabilities, however, is necessary for proper system engineering, especially when adversarial behavior is commonplace. It became clear that without the right computer-aided design (CAD) tools, professional engineering on blockchain-enabled networks would be practically infeasible." IMO, the launch and development of cadCAD is going to be a great step for legitimatizing token engineering as the professional discipline for the engineering of cryptoeconomic models and will be necessary for all [#dao](/crypto/new/dao) experiments.
