The study was undertaken in two stages: (i) interviews in 2016 that examine the barriers and drivers of diffusion; followed by (ii) a case study in 2019 of the Italian wine industry's permissioned blockchain. The results show that diffusion is reaching a final stage for permissionless blockchains but is lagging behind for permissioned blockchains due to the different barriers and drivers of diffusion. The implications from this study are that: (i) drivers and barriers for different types of technological innovation may be different and change over time; (ii) initial barriers may be surmounted and become features of the underlying technology; (iii) barriers may become drivers of a technology; (iv) drivers of one type of technology may spill-over to become drivers for another type; (v) diffusion may be measured by both the number of adoptions and the number of participants in that technology; (vi) off-chain processes may become a major barrier for permissioned blockchains; and finally (vii) self-interest may be the key driver of technological innovation.
