We now arrive at the last main pillar of the proposed token-based ecosystem design framework, namely, token design. Without detracting from the role of the other two, market and mechanism designs, token design is the most important one. The reason is that value and transactional calibrations enabled by the digital token are the crucial characteristics differentiating blockchain-based ecosystems from other physical, or indeed digital, ones. The reference token typology discussed near the end of Chap. 4 (Sect. 4.3 ) will be used here as a basis, upon which to explain the objectives, scope, importance, and material factors of token design.
