**5. Discussion**

The previous Section 2 introduces the M2X Economy, while Sections 3 and 4 focus on essential building blocks of the M2X Economy, i.e., M2X enactments, governance and smart-token economics. Subsequent sections discuss the arguments in favor and against our smart-contract enabled and blockchain-based M2X proposal as well as alternative approaches. Space constraints force us to focus on the most relevant aspects.
