We refer again to the analogy that was introduced in Chap. 6 , namely of designing the economics of a token-based ecosystem being akin to designing the economics of a new country. The token-based economic design framework followed in this book consists of three main pillars: market design defines the typology of economic agents active in the country and the possible ways for said agents to interact with each other; mechanism design prescribes the rules and incentives/disincentives of economic agent interactions; and token design describes the functioning of the country’s currency and stores of value. In this chapter we will expand on notions of the second pillar: mechanism design.
